In the current paper we aimed to establish the quality of integral raw milk gathered from Fleckvieh cows breed, through physical-chemical and biochemical analysis. The obtained results, at the end of determinations, were compared with the values indicated in ASRO Romanian Standard, SR 2418:2008 for integral raw milk and with the ones presented in the Guide for rearing of Fleckvieh cows breed. For establishing the quality we effectuated physical-chemical determinations for fat content the (%), protein titre (%), lactose (%), DM (%), NFDM (%), water content (%), ash (%), density (g/cm3), acidity (°T) and biochemical were made the reductase probe, methylene blue and resasurin method. For fat content the established mean value was 4.24±0.064% with 0.44% higher than the indicated value in the breed rearing guide. Regarding protein titre, standard allows a minimum value of 3.2%, rearing guide 3.29% and the value obtained by us was placed at a level of 3.35±0.008%. For lactose the obtained mean was 4.83±0.011% and regarding the content in NFDM was obtained a mean of 8.84±0.020%. Generally we can say that milk obtained from Fleckvieh cows breed, reared at Rediu Farm, was in according with the nowadays quality standards.

(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2018) Nistor, Andreea-Cătălina; Albu, Aida; Usturoi, Marius-Giorgi
An important and timely topic in the food industry, it is pasteurized liquid egg products, which have great utility in many industry and not only being sought ever more by consumers. The purpose of this paper is to verify nutritional properties and microbiological quality throughout the shelf life recommended by the manufacturer and to highlight their degradation. The physicochemical and microbiological quality assessment was performed on liquid pasteurized white and yolk, packed in a 2 kg bag-in-box in refrigerator (0 ... + 4 °C), and consisted in determining the pH value, nitrogen slightly hydrolyzable and microbiological analyzes were carried out according to the standards in force. The pH value increased during the shelf life from 8.29 (first day) to 8.98 (day 28), similar to pasteurized liquid yolk, the variation limits being between 5.93 and 6.04. Also, the slightly hydrolyzable nitrogen content was increased in the analyzed pasteurized liquid white (from 9.27 mg NH3/100 g on the first day to 14.73 mg NH3/100 g for the last day of storage), as well as in pasteurized liquid yolk to 6.57 mg NH3/100 g in the fresh product to 10.82 mg NH3/100 g in the stored product for 28 days). For the monitored microbiological indicators we also noticed an increase in their values during the storage period in the two types of analyzed egg products. The conclusion of the study is the highlight of existence a positive correlation between physical and microbiological indicators for both pasteurized liquid white and yolk analyzed.

Studies regarding qualtity of powder milk
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2018) Usturoi, Marius-Giorgi; Raţu, Roxana-Nicoleta; Usturoi, Alexandru; Avarvarei, Bogdan-Vlad
Powder milk is more and more utilised in food industry due to the fact that have the same nutritive value like whole milk, but the shelf life time is much longer, is almost free from microbiological point of view and present an easy way for storage/utilization. The aim of the research was to evaluate the quality of two assortments of autochthonous powder milk (whole-26% fat and skimmed-1.5% fat) by analyzing some physical-chemical indicators (acidity, solubility, as well as content in water, dry matter, fats and proteins) and microbiological (total number of germs), in according with the standard methods. Determinations showed that majority of quality indicators were between normal limits, for both categories of powder milk. For example, water content was lower with 0.66% (whole milk) and with 0.16% (skimmed milk) face to product standard, acidity was between the limits imposed by the producer and microbial charge was around 9.5 times lower than the maximum admissible value. The only problems were observed for products’ fat content (higher with 0.14-0.23% than the admissible maximum) and respectively for solubility (lower with 1.73-1.89% than the minimum indicated by standards) due, probably, to some errors during processing. The conclusion of the study was that analysed powder milk had suitable qualitative features, inclusive under microbiological aspect, fact which allows its utilisation, without any restrictions, in human nutrition.

Researches on the growth performance of the vietnamese pigs exploited in Romania
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2018) Hoha, Gabriel; Costăchescu, Elena; Nacu, Gherasim; Nistor, Cătălin-Emilian; Păsărin, Benone
Growth of vietnamese pigs has taken some measure among small breeders in Romania. Information on the breeding performance and qualities of these pigs is contradictory and sometimes exaggerated. The present paper aims to study reproductive and growth performance in 2 of the most widespread Vietnamese pig breeds in Romania: Mong Cai and Co. Reproduction performances were studied on 10 sows, 5 from each breed, for 3 litter. The production performance was performed on 40 pigs, male castrated and females, 20 of each breed, who were followed from weaning until 1 year of age. Results obtained for age of first estrus, litter size, weight of first day, weight of weaned pigs, parturition interval and number of parturition on year were as follows: 4-5 months, 6 – 8 piglets, 0.41 kg, 3-4 kg, 6 -7 months, 1.6 – 1.7 partutition for breed Co and 6-8 months, 7 – 12 piglets, 0.45 kg, 5 - 6 kg, 5 - 6 months, 1.5 - 2 partutition for breed Mong Cai. Similarly, growth results are higher at breed Mong Cai versus breed Co. As a conclusion, this breeds have performance for reproduction and breeding inferior to local breeds and we do not recommend them to grow.

Resistance particularities and curling of the curls at the Moldavian Karakul lambs
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2018) Buzu, I.
The purpose of this scientific paper was to focus on the peculiarities of resistance and rolling of curls at the Moldavian Karakul lambs, and to reveal the relations of these attributes with other qualities and characteristics of the skin for the improvement of the lamb selection procedures of the requested type. The scientific researches were carried out on the lots of Moldavian Karakul lambs from the ewe flock of Experimental House „Tevit” of the National Institute of Animal Husbandry and Veterinary Medicine (INZMV) from Maximovca village, Anenii Noi district and Agricultural Production Cooperative (APC) "Agrosargal" from the Sarata Galbena village, Hânceşti district. The nonparametric properties of the curl have been researched according to the methods elaborated or perfected by us, in accordance with the Karakul ewe Guidelines for Breeding with the amelioration principles in the Republic of Moldova. It was found that with the increase of the length of the curls from the short to the very long category, increases the share of lambs with excellent resistance from 3.9% to 100% or by 96.1% (td = 36.7; P < 0.001) and, at the same time, lowers the low lame weight with low and insufficient curls strengths from 85.7% to 0.0% (td = 6.0; P <0.001). With the increase in the degree of silkiness of the sheathing of lambs from reduced to excellent, the overall weight of individuals with the excellent and suitable curls strength is significantly increased from 46.3% to 91.7% or by 45.4% (td = 9.2; P < 0.001). For lambs with jacket curl type, the mixed (59.5%) and cranial (32.5%) of curls rolling direction is characteristic. For the lambs with the flat and coastal curl type it is characteristic the caudal direction of curls rolling (92.4 and 95.0% of the cases). Lambs with the type of kaukasian curl have, for their part, an indeterminable direction (60.8%) of curls rolling. It is considered that the lower degree of laughter in lamb is more advantageous because it offers the possibility of retaining the lamb for a few days (4-5 days) before slaughter until the degree of ablation reaches 10-11 points. During this time, the surface of the skin and the body mass of the lamb will increase, which leads to the obtaining of the economic benefits. The most desired degree of rolling at birth is considered to be 5-7, while grade 10-11 already indicates the need to slaughter the lamb. Finding that the degree of the curls rolling increases daily by 0.3 points and the lamb can be retained until reaching 10.5 points, we have determined that lambs with jacket curl can be detained up to at slaughter for 1-2 days, those with the type of coastal curl 4-5 days, those with the type of flat curl 6-7 days, and those with the kaukasian curl require urgent slaughter. As a result of the research, the following conclusions were deduced: the strength and elasticity of the curls at the Moldavian Karakul lambs is in a phenotypical correlation positive and evident with the length of the curls, the fibres density and the density of the skin, and, at the same time, negative with the length of the fibres. The best resistance of the curls is found at the lambs with valuable, long and very long curls, with short and med. long fibres, with excellent and suitable silk, with supple and dense skin; The direction of curl abutment is in positive correlation with the type of modelling, with the qualities of the fibres, especially with their silk and gloss. So, the better the qualities of the hairpiece, the more the rolling direction of the curls is more valuable - to the head, tail or mixed (sinusoidal); The rolling degree of the curls is in a genetically negative (but beneficial for selection) relationship with the type of curl and the lamb class at the evaluation. The smallest degrees (but, desired - 6 and 7 points) are recorded in lambs with med. and large curls, with flat, costal, and jacket type of curl. The highest degree of rolling (undesired - 12 points) was recorded at lambs of class II with the type of kaukasian curl; The knowledge of the resistance and elasticity relationships, as well as curling of the curl with a string of other characters of the curls and hair fibres allowed the selection of the most valuable lambs in the breeding lots of the new sheep type Moldavian Karakul.
