    ("Ion Ionescu de la Brad" Iași University of Life Sciences, 2022) Martinescu, Gabriela-Victoria; Petrescu, Cristian; Andronic, Bianca-Lavinia; Mardare Mîndru, Raluca; Ivănescu, Maria-Larisa; Miron, Liviu-Dan
    In order to evaluate the prevalence of heartworm disease in the South-East of Romania, we collected blood from 40 dogs from a shelter in Galati, which were examined by several methods for the Dirofilaria immitis and Dirofilaria repenes microfilariae identification, and for the detection of Dirofilaria immitis antigen respectively. Eleven dogs were positive for microfilariae (27.5%), of which 3/11 were co-infections and only 1/40 had D. repens microfilariae detected. Following serological test, D. immitis antigen was detected in 30% of the investigated serum samples (12/40). The high prevalence of heartworm disease requires continuous monitoring of symptomatic dogs, but also of the asymptomatic ones from shelters or of those from veterinary clinics in endemic areas. Furthermore, the mosquito populations control in endemic areas is mandatory.

    ("Ion Ionescu de la Brad" Iași University of Life Sciences, 2022) Martinescu, Gabriela-Victoria; Ivănescu, Maria-Larisa; Mardare Mîndru, Raluca; Andronic, Bianca-Lavinia; Miron, Liviu-Dan
    Dogs and cats play an important role in the spread of tick species and in the transmission of pathogens. Dermacentor reticulatus occurs in areas by varied types of climate, vegetation and a high availability of potential hosts, while Ixodes ricinus follows a similar seasonal pattern each year. This study was carried out between 2017 and 2021, where we examined 189 canine patients of different breeds, aged between 2 months and 18 years. We collected 435 ticks which were placed individually according to the animal in eppendorf tubes in ethyl alcohol and numbered, until morphological identification. The collected ticks were predominantly adults with different feeding status, belonging to the species: Ixodes ricinus (41.6%), Dermacentor reticulatus (57.7%) and Rhipicephalus sanguineus complex (0.69%). Dermacentor reticulatus was predominant, with two peaks of activity in spring and autumn. We also found 2 specimens of D. reticulatus males, in January, outside the normal period of activity. The second species identified, Ixodes ricinus, shows three peaks of activity, having the most intense period of activity in the spring months. The second peak is observed in summer, and the third in autumn. The prevalence of the species Rhipicephalus sanguineus complex is low, of only 0.69% of the total ticks collected from dogs.The aim of this study was to determine the prevalence of tick infestations collected from canine patients, in order to assess a possible change in the activity periods of the species.

    Non-destructive methods of milk quality assessment
    ("Ion Ionescu de la Brad" Iași University of Life Sciences, 2022) Ariton, Adina-Mirela; Neculai Văleanu, Andra-Sabina; Sănduleanu, Cătălina; Postolache, Alina-Narcisa; Poroșnicu, Ioana; Mădescu, Bianca-Maria; Crivei, Ioana-Cristina; Ungureanu, Elena; Trincă, Lucia-Carmen
    Monitoring the quality of raw cow milk is essential to maintain food safety and human health. To guarantee the quality and safety of milk, easy-to-use non-destructive analysis methods are available. Non-destructive methods have made progress, being useful for obtaining quantitative and qualitative data, destroying the sample, and offering several advantages, such as high sensitivity, adequate response time, and minimal sample preparation. Conventional methods are laborious, destructive, toxic, and time-consuming, require fully equipped laboratories and skilled personnel, extensive sample preparation, and are not suitable for real-time continuous monitoring of milk quality. The rapid development of non-destructive methods for the evaluation of milk quality consists of applications based on imaging, near-infrared spectroscopy, conductivity, biosensors, and ultrasound. This paper presents different non-destructive methods applied to determine the physicochemical parameters of raw milk (fats, proteins, lactose, casein, dry matter, acidity, density), the number of somatic cells, and the microbiological load.

    Applications of clinoptilolite in veterinary medicine and animal husbandry
    ("Ion Ionescu de la Brad" Iași University of Life Sciences, 2022) Ariton, Adina-Mirela; Neculai Văleanu, Andra-Sabina; Sănduleanu, Cătălina; Crivei, Ioana-Cristina; Postolache, Alina-Narcisa; Poroșnicu, Ioana; Mădescu, Bianca-Maria; Ungureanu, Elena; Trincă, Lucia-Carmen
    Zeolites are compounds of either natural or synthetic origin and have been employed successfully in a number of industries, including veterinary medicine and animal husbandry. Clinoptilolite is the form of naturally occurring zeolite that has undergone the most scientific study out of the 140 various varieties and is also used the most as a component in animal feed. Natural clay minerals and zeolites are administered with encouraging results due to their detoxifying, antioxidant, hemostatic, anti-diarrheal, and immunostimulant properties. In this paper, the characteristics and possible applications of clinoptilolite as an animal feed additive in order to prevent and/or treat particular diseases in dairy cows will be discussed. Natural and manufactured zeolites have been used as feed additives in cow nutrition, primarily to reduce the absorption of mycotoxins through the gastrointestinal tract, improve general health status, and increase overall animal performance. Clinoptilolite is marketed as a feed additive that helps maintain and improve the fertility, well-being, and productivity of cattle.

    A case of pericarditis in Angus cattle
    ("Ion Ionescu de la Brad" Iași University of Life Sciences, 2022) Anton, Alina
    A 10-years-old Angus cow was evaluated on the field for suspected traumatic pericarditis. Physical exam findings included tachycardia, mixed dyspnea, decreased intensity of heart sounds on the left, absence of heart sounds on the right but presence of fluid sounds, bilateral turgidity of the jugular veins, positive venous compression test, brisket and ventral abdominal oedema. The cow exhibited light pain while palpation at brisket region. Hematology revealed significant erythrocytopenia, higher hematocrit, lower hemoglobin concentration, significant leukocytosis with neutrophilia and lymphocytopenia. Serum biochemical findings had reduced glucose, urea nitrogen, albumin, sodium, potassium, chloride, calcium, phosphorus levels and increased levels of AST, ALT, GGT, total protein and globulin. Ultrasonography has shown pericardial effusion and strands of fibrin. The prognosis was poor, and pericardiocentesis or pericardiotomy were inadequate methods of treatment, thus euthanasia was indicated.

    Improving fertility in multiparous cows by inducing ovulation with GnRH agonist - gonadorelin or human chorinic gonadotrophin
    ("Ion Ionescu de la Brad" Iași University of Life Sciences, 2022) Borș, Silviu-Ionuț; Crivei, Ioana-Cristina; Borș, Alina; Crivei, Luciana-Alexandra
    This study was designed to assess the effects of the GnRH agonist gonadorelin and human chorionic gonadotrophin administered at first artificial insemination on the fertility of lactating dairy cows. The lactating dairy cows were divided into three groups: the hCG-group consisting of primiparous and multiparous cows that expressed the specific behavior of estrus with AI 12 hours after the end of estrus along with administration of 1500 IU of human chorionic gonadotropin (hCG); the GnRH-group consisting of primiparous and multiparous cows that showed the specific behavior of estrus with AI 12 hours after the end of estrus along with administration of 2 mL of Gonadorelin; and the control group (C-group) consisting of primiparous and multiparous cows that showed the behavior specific to estrus and that were artificially inseminated (AI) 12 hours after the end of estrus signs without any treatment. According to our results, administering GnRH agonist or hCG products to multiparous cows in order to induce ovulation increases the pregnancy rate during the first artificial insemination (46.6%, 57.1% vs. 22.2%, P ≤ 0.05). Both products don't have any effects on primiparous dairy cows (45%, 42.9% vs. 50%, P > 0.05).

    Inducing ovulation with human chorionic gonadotrophin improves cumulative pregnancy rates of dairy cows during the warm season
    ("Ion Ionescu de la Brad" Iași University of Life Sciences, 2022) Borș, Silviu-Ionuț; Crivei, Ioana-Cristina; Borș, Alina; Crivei, Luciana-Alexandra
    This study was designed to assess the effects of the GnRH agonist gonadorelin and human chorionic gonadotrophin, during a timed artificial insemination program, on the fertility of lactating dairy cows during the warm and cold seasons of the year. Cows were treated intramuscularly with GnRH-agonist (Day 0) and PGF2α (Day 7), followed by either GnRH-agonist (GPG treatment; 38 animals) or hCG (GPH treatment; 26 animals) on Day 9. All cows were fixed-time inseminated (TAI) 16–22 h after the end of treatment. In this study, replacing the Day 9 dose of GnRH with a dose of hCG may result in an increase in the cumulative pregnancy rate (46.6% vs. 25%, P ≤ 0.05) but not the pregnancy rate (26.6% vs. 18.8%, P > 0.05) in heat-stressed cows (THI > 70). However, in cold season, no effects were observed in the pregnancy rates or cumulative pregnancy rates of the examined cows. This finding indicates that hCG therapy in TAI programs may mitigate the negative effects of heat stress on dairy cows reproduction. This tendency can be explained also by some studies that have shown that hCG can significantly reduce the number of small luteal cells while increasing the number of large luteal cells as the corpus luteum gets bigger in diameter, area, and volume.

    Monitoring, prevention and treatment as key pillars in the management of bovine mastitis
    ("Ion Ionescu de la Brad" Iași University of Life Sciences, 2022) Neculai Văleanu, Andra-Sabina; Ariton, Adina-Mirela; Mădescu, Bianca-Maria; Poroșnicu, Ioana; Crivei, Ioana-Cristina; Radu, Ciprian
    The quality of milk is a component based on certain individual indicators that allow the correct assessment of the quality of the dairy product starting from the producing animal, the quality of the feed, the exploitation system, the state of health, milking hygiene, the storing and transportation conditions of milk towards the processing unit. The purpose of this study was to monitor udder health and establish a proper treatment based on a specialized protocol that employs the assessment of physicochemical milk parameters, number of somatic cells, as well as identification of the pathogen agent generating the disease. Milk samples from 69 dairy cows were collected at the beginning and middle of lactation, a total number of 19 cases of clinical and subclinical mastitis cases being observed. The physicochemical parameters of milk, somatic cell count, and pathogen prevalence were assessed. A very small significant negative relationship was observed between somatic cell score and lactose percentage, (r = 0.667, p < .001). The most frequent encountered pathogens were Streptococcus spp. A management approach for mastitis, as well as other diseases, should include the following major components: prevention, monitoring, and diagnosis.

    On-farm milk culturing for bovine mastitis management
    ("Ion Ionescu de la Brad" Iași University of Life Sciences, 2022) Neculai Văleanu, Andra-Sabina; Ariton, Adina-Mirela; Mădescu, Bianca-Maria; Poroșnicu, Ioana; Radu, Ciprian
    Bovine mastitis is the most common reason for antibiotic usage in dairy cows, its costs being estimated at more than $350 per mastitis case. Accurately identifying the bacterial species at the core of a mastitis infection may help narrow down treatment choices and cut down on the overuse of antibiotics. The aim of the present study was to evaluate the prevalence of etiological agents in milk samples from cows with clinical mastitis using commercially available culture plates (ClearMilk, LabMediaServis, Czech Republic). Briefly, milk samples were collected from udder quarters with clinical mastitis and were aerobically cultured using the on-farm culture system. If two prominent mastitis pathogens were identified, the sample was labelled as "mixed growth," and if three or more pathogens were observed, it was labelled as "contaminated". Our results indicate that ClearMilk might be an useful on-farm milk culturing tool for detecting pathogens linked with bovine mastitis.

    ("Ion Ionescu de la Brad" Iași University of Life Sciences, 2022) Bojkovski, Jovan; Kureljušić, Branislav; Prodanov Radulović, Jasna; Aniță, Dragoș-Constantin; Ludu Oșlobanu, Luanda-Elena; Aniță, Adriana-Elena; Angjelovski, Branko; Zdravković, Nemanja; Pavlović, Ivan; Kureljušić, Jasna; Arsić, Sveta; Nedić, Sreten; Đurić, Miloje; Tzika, Eleni; Tsakmakidis, Ioannis A.; Mitrović, Aleksandra; Prodanović, Radiša
    Susceptible categories of pigs for the occurrence of respiratory diseases are categories in postweaning and fattening. The spectrum of clinical symptoms is very wide and includes not only respiratory symptoms, but also many other symptoms that appear as a consequence of systemic disorders, depending on the type of causative agent. Cough can be of different frequency, intensity and productivity, and difficulty breathing can be of different degrees. Respiratory diseases may be accompanied by stunted growth, rough bristles, anorexia, reduced daily gain and lethargy. Disseminated systemic disorders often include symptoms suggestive of central nervous system disorders, swollen joints and lameness, followed by reproductive disorders or sudden death. Pathomorphological changes are also of different character and severity. Nonspecific factors predispose to the occurrence of initial damage or contribute to the further spread of already existing lesions. In this article, we wanted to give an overview of our research on respiratory diseases of viral etiology in pigs from commercial farms.

    Long term monitoring of a cat with idiopathic mediastinal cyst
    ("Ion Ionescu de la Brad" Iași University of Life Sciences, 2022) Turcu, Cătălina-Andreea; Baisan, Radu-Andrei; Condurachi, Eusebiu-Ionuț; Vulpe, Vasile
    Mediastinal cysts are previously described as incidental findings in cats. A nine years old, 2.8 kg, Persian cat was presented to out Veterinary Teaching Hospital (VTH) for mild dyspnea. Chest radiographies, revealed an incapsulated soft tissue opacity in the cranial mediastinum. Thoracic lung ultrasonography (LUS), evinced the presence of a cyst-like structure. Furthermore, the cat was subjected to complete cardiological examination and complete blood analysis. Echoguided drainage followed by cytological examination was carried out in order to reach a definitive diagnostic and to improve the general status of the patient. No other medical treatment has been pursued. Monthly evaluations have been performed during a period of five months, and the drainage was repeated one more time until the complete resolution of the pathology. No signs of relapse have been noticed over a period of two years. Only four cats diagnosed with idiopathic mediastinal cyst have been mentioned in the literature. To the author’s best knowledge, this is the first case report which describes the dynamic evolution of an idiopathic mediastinum cyst in Persian cat presented for mild dyspnoea.

    Applicability of thoracic non-cardiac ultrasonography in the diagnostic protocol of acute dyspnoea in feline patients
    ("Ion Ionescu de la Brad" Iași University of Life Sciences, 2022) Turcu, Cătălina-Andreea; Baisan, Radu-Andrei; Condurachi, Eusebiu-Ionuț; Vulpe, Vasile
    Lung ultrasonography (LUS) is a non-invasive and rapid method used for the diagnostic of respiratory diseases in all mammals. The changes in clinically observed respiratory patterns can be correlated with the modifications observed during transthoracic ultrasonography, thus the clinician can select an appropriate protocol for managing the animals with respiratory distress. The aim of this study is to emphasize the clinical utility of lung ultrasonography when dealing with cats in an emergency setting. Cats presented with respiratory distress were retrospectively reviewed and classified based on the aetiology of the disease. Lung ultrasonography was performed using the thoracic fast protocol (T-FAST). Vet BLUE ultrasonography and chest radiography were performed only when the clinical status of the patient was suitable for these diagnostic methods. Thirty-nine cats met the inclusion criteria. The presence of free fluid, B-lines, shred sign, nodule sign, organ sign and barcode sign have been assessed for each patient. Based on the findings, a differential diagnostic and a management protocol had been proposed. Lung ultrasonography is a non-invasive, stress-free and fast examination with high sensibility and specificity for diagnosing cats with breathing difficulty.

    Monieziais of ruminant in Serbia – preliminary observations
    ("Ion Ionescu de la Brad" Iași University of Life Sciences, 2022) Pavlović, Ivan; Zdravković, Nemanja; Radanović, Oliver; Bojkovski, Jovan; Petrović, Milan P.; Caro Petrović, Violeta; Stojanov, Igor; Minić, Stanko; Csordás, Ferenc; Dobrosavljević, Ivan; Radović, Bisa; Milanović, Valentina; Mladenović, Vladica; Stanojević, Slobodan; Tasić, Aleksandra; Relić, Renata
    Monieziais is a global parasite disease of ruminants. It is caused by Moniezia expans and Moniezia benedini. As all tapeworms, Moniezia spp has an indirect life cycle with ruminants as final hosts, and oribatid mites (also called "moss mites" and "beetle mites") as intermediate hosts. The oribatid mites ingest the eggs, which hatch in their gut and develop to cysticercoids in the body cavity of the mites. They are infective for the final hosts. These thugs inhabit the small intestine of the host and clinical presentation is most common in young animals. There are disorders of profuse diarrhea, intestinal convulsions and obstruction, bloated abdomen, cachexia and death. Research on the prevalence of monieziais in ruminants has not been done in Serbia for more than fifty years. In our work, we presented the results of a preliminary examination of the prevalence of monieziais in certain regions of Serbia in large and small ruminants in the last ten years. Moniezia benedeni is a common tapeworm of cattle in Serbia and depending on the region, the prevalence is 3 to 5%. Moniezia expansa is more frequent in sheep and goats and occured in 11 to 23% of examined animals. Diagnosis is based on fecal examination for the presence of gravid segments (proglottids) or of eggs with a characteristic morphology. In the treatment of the disease, the most commonly used preparations are bezamidazole, niclosamide, and combination of praziquantel and levamisole.

    Epidemiological impact of swine zoonotic digestive viruses – review
    ("Ion Ionescu de la Brad" Iași University of Life Sciences, 2022) Aniță, Adriana-Elena; Aniță, Dragoș-Constantin
    Infectious diarrhea of farm pigs causes some of the most significant financial losses for producers working in the pork industry through the loss of efficiency, as well as the loss of overall profitability of production. Highly virulent diseases, such as porcine epidemic diarrhoea, result in very high piglet mortality, causing producers enormous financial difficulties. Recurrent and less endemic diseases however, have greater long-term overall effects on health and productivity. The prevalence of swine diarrhea can vary from country to country, from one farming system to another and even from one farm to another. The increasing pressure of pig production, the wide network of imports-exports, the constant evolution of pathogens that allow them to develop new adaptation and diversification mechanisms, and climate change, are some of the challenges faced by the global pork industry. Thinking about viruses being transmitted across species implies taking into consideration all issues arising from these pathogens. They not only reveal the vulnerabilities in human societies, whose functioning is disrupted by these outbreaks, but also the fragilities of the environments in which they appear.

    Clinical and paraclinical aspects in the acute diarrheal syndrome in dogs
    ("Ion Ionescu de la Brad" Iași University of Life Sciences, 2022) Boghian, Vasile
    The aim of this paper was to identify the clinical and paraclinical diagnostic elements of acute diarrheal syndrome in dogs, useful in streamling of treatment. The clinical diagnosis in haemorrhagical acute diarrheal was easy to establish given the profoundly altered general condition with cortical inhibition and melena; sometimes it has been clinically evolve as dysentery (frequent bloody defecation). In catarrhal acute diarrheal, it can sometimes be profuse (exhausting), accompanied by alteration of the patient's general condition and drowsiness. The ultrasonographical examination revealed inflammation of the intestinal wall with a hyperechoic appearance and a halo exterior hypoechogenic corresponding to parietal congestion. The haematological examination revealed hypochromic, normocytic anaemia and a systemic inflammatory syndrome (increased WBC=17.2±0.3x10³/mm³, decreased RBC=5.3±0.4x106/mm³, HGB=11.8±0.4 g/dl and CHEM=31.0±0.2 g/dl). The blood biochemical examination showed subclinical liver failure without impairment of renal and exocrine pancreas functions. The sero-haemorrhagical acute diarrhea had clinically manifested by cyclic episodes of diarrhea. The radiological examination revealed inflammation of the intestinal mucosa and the presence of superficial ulcers, and the coproparasitological examination confirmed cryptosporidiosis. On the other hands, the sero-haemorrhagical acute diarrhea was the consequence of traumatic gastroenteritis, confirmed by radiological exam (dense, radiolucent contents in the gastrointestinal mass). In this situation, the haematological examination revealed a systemic inflammatory process (increased WBC=18.0±0.3x10³/mm³) and hypochromic, normocytic anemia (decreased CHEM=31.8±0.3 g/dl). The blood biochemical examination revealed subclinical liver failure (increased ALT=88.2±0.3 IU/L and ALP=120.3±0.4 IU/L, values only).

    The presence of digestive parasites can alter behaviour, fertility, body condition, juvenile development, decreased resistance to other pathogens, or the performance for which animals are bred. The aim of this study was to monitor gastrointestinal parasite infestation in equines in Mehedinți County. The horses, sport and working, various breeds and half-breeds, came from different localities from Mehedinți County. Samples were collected in plastic bags and examined by flotation, sedimentation, and Baermann methods. Horses were divided into several categories: sex, age, breed, and service. Strongylidae and Parascaris spp. represented parasitism in recreational and working horses studied in Mehedinți county, no other parasitic elements were identified. The overall prevalence was 43.5% for Strongylidae and 21.17% for Parascaris spp. The simultaneous presence of at least two parasite species was observed in 17.64% of the horses examined.

    Observations on sensitivity and AMR of E.coli in pigs and humans
    ("Ion Ionescu de la Brad" Iași University of Life Sciences, 2022) Lungu, Bianca-Cornelia; Tudor, Beatrice Ana-Maria; Georgescu, Ovidiu-Ionuț; Spătaru, Ioana-Irina; Torda, Iuliu; Mircu, Călin; Huțu, Ioan
    Antimicrobial resistance of pathogenic E. coli impacts the swine industry due to the limited treatment options and growing public health concerns caused by potential transfer of antimicrobial resistance genes into the food chain. The study was carried out throughout the whole year; the samples were collected from the small intestine following necropsies performed in young pigs. From a laboratory database, 78 samples were positive for E. coli and were sampled and processed in order to describe the AMR following a classical microbiological exam. Each sample was cultured on selective media (Mac Conkey Agar) and antibiograms were performed using MicroScan Walk Away System. The antibiogram examinations were performed for 20 antibiotics and the results were presented in the form of the following categories: resistant, intermediate, susceptible. In 4 of the 20 antibiotics tested, the bacterial agent showed a sensitivity of over 85% and in 6 of the 20 antibiotics, it showed resistance of over 85%. On average, 47.8±37% of E. coli showed sensitivity to the 20 antibiotics tested and 48.5±38% resistance; 3.2±4% were classified as “intermediate”. Similarities were noted in terms of sensitivity and resistance between the antibiograms from animal E.coli versus human E.coli. The same sensitivity was observed in 5 of the 20 antibiotics, and in 3 of the 20 antibiotics we noticed common resistance, but a future molecular biology analysis will be performed in order to identify the genes associated with AMR.

    Corn protein content – a comparison between methods, analysors and farmers’ expectations
    ("Ion Ionescu de la Brad" Iași University of Life Sciences, 2022) Lungu, Bianca-Cornelia; Ionescu, Cătălin; Tudor, Beatrice Ana-Maria; Georgescu, Ovidiu-Ionuț; Mircu, Călin; Huțu, Ioan
    In a process of problem solving and diet formulation the analysis offeed ingredients’ proteins have to be done accurately, rapidly, cheep and if is possible at the farm level. As a general rule the accurate methods last too long and real time methods are not so exactly. The study is doing the comparison between the results of three methods 1. Classical chemistry (Kjeldahlmethod), 2. Near infrared spectroscopy analysis (NIR) and 3. By FT-NIR spectrometer used for analyzing the corn’s protein content. The “reference sample” was considered the result obtained from classical chemistry - Kjeldahl method and the comparison was between classical, NIR and FTNIR methods, for corn's grains and corn’s flour. Each measurement was performed twice and no significant difference was found between repetitions (p<0.00). The average protein content in corn for 39 samples was 7.82±0.16% by Kjeldahl method, by NIR equipment, 7.47±0.17% in corn’s grains and 7.57±0.15% in corn’s flour and by FT-NIR equipment, 8.40±0.29% in corn’s grains and 7.80±0.12% in corn’s flour.Comparing the results of NIR and FT-NIR measurements with Kjeldahl method results significant differences between first measurement (F=3.625 at p =0.007), second measurement (F=3.255 at p =0.013) and average measurements (F=3.486 at p =0.009). The smaller differences between reference results was in case of FT-NIR in corn’s flour (0.02%) but were no significant differences by Turkey test comparison for any of NIR, FT-NIR, grains or flour. In conclusion, irrelevant to the method or equipment used for measurements it appears more feasible to run the samples at farm level.

    Assessment of the technological parameters of butter production and the influence of the storage conditions on its freshness
    ("Ion Ionescu de la Brad" Iași University of Life Sciences, 2022) Petcu, Carmen-Daniela; Tăpăloagă, Dana; Ciobotaru Pîrvu, Emilia; Oprea Mihai, Oana-Diana; Ghimpețeanu, Oana-Mărgărita; Murariu, Otilia-Cristina
    Butter is the dairy product obtained by processing cream. It is a food rich in nutrients and is characterized by a very high digestibility. In the study carried out in a dairy products processing unit, located in the south of Romania, the technological flow of obtaining different types of butter, as well as their physico-chemical characteristics were followed. Laboratory determinations were carried out regarding the freshness of the butter (organoleptic examination, acidity determination, Kreiss reaction etc.). At the same time, a questionnaire was carried out in which 170 people participated, regarding the consumption of butter, a study performed through the Google forms platform. Following the determination of the acidity of the fresh, refrigerated and frozen butter samples, values below the maximum allowed limit were recorded, all samples being considered compliant, and the butter samples stored at temperatures higher than 4oC exceeded the maximum allowed value from the first days of the deviations temperature, being classified as noncompliant products. This aspect highlights the importance of respecting the storage conditions recommended by the manufacturers. Following the opinion poll on butter consumption, 71.2% confirmed the preference to consume butter in the morning. For most participants, the producing company is the determining factor in the choice of butter.
