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. Key words: Peculiarities, resistance, elasticity, curling, curl, Moldavian Karakul

Study on the dairy cows breeding in farms from the eastern cross-border area of Romania
(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2018) Maciuc, Vasile; Korlyuk, S.; Tarasenko, Ludmila; Nistor, Cătălin-Emilian
The paper was meant to be an analysis of the actual number of bovines, type and size of holdings, technical endowment of the holdings, as well as the welfare norms of the animals in the Romanian cross-border area. The research took place between 2013 and 2015 in the Romanian, Ukrainian and Republic of Moldova cross-border area. The situation of the shelters in the Romanian cross-border area is the following: 5.6% of the holdings have accommodation spaces for one animal; 31.34% of the holdings have accommodation spaces for two animals (adult animal + youth); 3.7 % of the holdings have accommodation spaces for three animals (adults + youth); 1.98% of the holdings have accommodation spaces for four animals; 0.8 % of the holdings have accommodation spaces for five animals; 36.06 % of the holdings have accommodation spaces for adult + youth bovines and for equines; 21.11% of the holdings have accommodation spaces for bovines (adults + youth), ovine and swine. Among the 26 districts of the Odessa region, Ukraine, the number of cattle’s registered a slight increase in only 12 districts, with a decreasing number at the level of the total cross-border area. In the Republic of Moldova, the number of bovines for all categories of farms decreased. If on January 1st 2006 the total number represented 311 thousand pieces, including 217 thousand cows, on January 1st 2013 there were 191 thousand, respectively 134 thousand pieces or 38.5 respectively 38.2 % less. Situation in the agricultural sector in similar. The reduction of the total number of bovines, as well as of the total number of cows represented 50%. Starting with 2008, when referring to farms, we can mention an increasing trend of the complement of bovines, increased by 2.5 times on January 1st 2013 both for the total number, as well as for the number of cows. As regards the population’s farms, which comprise most of the complement, this decreases from year to year, from 291 thousands in 2006 to 180 thousands in 2013 or by 38.2%, including cows, from 209 thousands to 130 thousands or by 37.8%. We hereby ascertain that both in the Romanian cross-border area and in the Ukrainian and Republic of Moldova cross-border area, the assignment of the factors of production in the analyzed farms, of high or family-type complements, is under the actual need, as the current conditions, mainly the financial conditions, only allow the use of certain factors of production (race, fodder). If in Romania European financing contributed to the performance improvement, farmers in Ukraine and the Republic of Moldova face high deficiencies.
