RIULS

Repository of Iasi University of Life Sciences, ROMANIA

Welcome to RIULS!

The mission of the University’s institutional repository is to manage, preserve and disseminate, in open access, the academic and institutional output of the university’s academic community. It also aims to promote values and personalities belonging to Romanian agricultural science, by storing digitized versions of rare books and manuscripts from its collections.

The repository is part of the international movement known as open science, which promotes free access to scientific literature. This translates into maximized impact of the work carried out by researchers, contribution to improving access to knowledge, increased visibility of the institution through the works of its authors and improvement of its search engine ranking.

All documents deposited in the repository receive a unique and persistent identifier called a Handle, thus guaranteeing perpetual access to scientific output through permanent links.

RIULS Repository of Iași University of Life Sciences is indexed in Duraspace, OpenDOAR,CORE,Google Scholar,BASE (Bielefeld Academic Search Engine) and ROAR (Registry of Open Access Repositories), global Directories of Open Access Repositories.

    Incidence of repeat breeding syndrome in holstein friesian cattle
    (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Crivei, Ioana-Cristina; Ruginosu, Elena; Sănduleanu, Cătălina; Borș, S.I.; Bugeac, T.; Dascălu, L.D.; Creangă, Şteofil
    Repeat breeding syndrome could be described as a cow's failure to conceive after three or more than three inseminations in the absence of any clinically relevant abnormality. In order to determine the incidence of repeat breeding, a retrospective study which included data from 682 Holstein Friesian cows within two dairy herds across Belgium were collected during two consecutive years. Thus, the repeat breeding overall incidence in dairy cattle was 18.1% (124 cows). The highest incidence of repeat breeding syndrome was recorded during spring season (5.6%, n=38) the lowest incidence being during winter season (2.9%, n=20). Regarding postpartum disorders, our study revealed that in cows with endometritis, metritis, milk fever and retained fetal membranes, the incidence of repeat breeding was higher than in cows that became pregnant within first three artificial inseminations (were considered to have normal fertility). According to parity number, the highest incidence of repeat breeding syndrome was recorded during 1st (3.9% n = 27) and 5th (4.1%, n = 28) parities, the lowest incidence being recorded during 6th (1.9%, n = 13) and 7th (0.29%, n = 2). Also, in cows with repeat breeding, the reproductive indices were negatively modified, triggering thus a poor reproductive performance. In conclusion, our results show that repeat breeding syndrome involves a various number of factors, such as postpartum disorders as well as extrinsic factors.

    Effect of zinc intake during transition period on zinc and calcium in milk of subclinical hypocalcemia dairy cows
    (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Mayasari, Novi; Nurjanah, Laela Tien; Setyowati, Endang Yuni; Salman, Lia Budimulyati
    In early lactation, high producing cows frequently suffer from negative energy balance and mineral imbalances. Negative energy balance is associated with immune suppression and some diseases like a hypocalcemia. Zinc (Zn) is known as immune stimulator, able to increase immune response to diseases. The objective of this study was to study the effect of supplemental Zn intake in dairy cows at 4 weeks prior to calving (dry period) on Zn and calcium (Ca) content in milk and subclinical hypocalcemia. Twenty-two dairy cows (Holstein Friesian) were randomly allocated to either a dry cow ration with or without Zn supplementation (40 ppm Zn in the diet). The cows received a roughage mixture ad libitum and concentrates were fed individually. Post-partum, cows were milked twice daily and throughout the experiment animal health was monitored daily. Blood and milk samples were taken at week 1 after calving. Data were statistically analyzed with SAS. A cow was considered a case of subclinical hypocalcemia when blood calcium lowered below 8.0 mg/100 ml. The results showed the percentage incidence of clinical and subclinical hypocalcaemia (1.5% vs. 31%). Zn and Ca content in milk were not affected by dietary Zn content in diet. In conclusion, feeding above Zn requirements during 4 weeks before calving does not seem to reduce the incidence of clinical milk fever nor subclinical milk fever. Zn supplementation may improve the immune system but its form and absorption must be considered.

    Association between plasmatic glucose and urea in dairy cows with subclinical hypocalcemia
    (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Mayasari, Novi; Nurjanah, Laela Tien; Setyowati, Endang Yuni; Arfiana, Andri; Sitanggang, Fajar; Salman, Lia Budimulyati
    During transition period, cells epithelial mammary gland differentiates massively in order to support milk production. The major mineral in milk is calcium, excreted in large amounts, while simultaneously maintaining maternal health and physiology (including energy status). The objective of this study is to evaluate the association between plasma glucose and urea in dairy cows with subclinical hypocalcaemia. In total 22 Holstein were used in this study. To analyze the association between glucose and urea, in total 12 Holstein dairy cows with subclinical hypocalcemia (Ca<0.1 mmol/L at d 2) were used in the experiment. Cows were blocked based on calving date and parity. Blood samples were collected approximately on d 7 postpartum for measurement of plasma glucose and urea nitrogen. Disease occurrence was determined based on individual treatment records. Pearson correlations coefficient were used to analyze the correlation between blood metabolites. Subclinical hypocalcemia cows had normal concentration of glucose and urea on d 7. The results shown that the concentration of glucose as indicator for energy status were negatively correlated with plasma urea. No differences were observed between individual of cows in the occurrence of subclinical and clinical hypocalcemia, clinical mastitis, displaced abomasum, dystocia, retained placenta, metritis. These data suggest that early lactation energy status indicated by glucose and urea differs among cows with subclinical hypocalcemia.

    Research on the biochemical particularities of horses blood slaughtered for human consumption
    (“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2019) Boişteanu, Paul-Corneliu; Lazăr, Roxana; Ciobanu, Marius-Mihai; Diaconu, E.C.; Diaconu, Nicoleta
    In order to read and explain the physiological status it is important to know the metabolic integrity of the animals by performing hematological and biochemical examinations. The cellular components of the blood reflect specific changes in an organ or system of the body, or most often an animal's response to certain physiological or pathological conditions. The research was carried out on for groups L1 – young females; L2 – young males; L3 – adult females; L4 – adult males in order to appreciate the biochemical values for evaluating the morphophysiological status before slaughtering horses and improving their welfare factors. The collection of blood samples was performed with the vacuum system. Biochemical parameters were determined by spectophotometry using the ACCENT 200. The biochemical profile analyzed before pre-slaughter demonstrate a good maintenance status, received a proper feeding, which reflects on the final meat quality.
