However, the same statistics reveal that the buffalo number has declined tragically to 142.000 heads in 2016 while 1.140.000 buffalos existed in 1961 in Turkey. In this study, a survey, which was conducted in buffalo breeding farmers in the Aydin Province situated in Aegean Region in Turkey, was evaluated with its results in order to determine the general state of buffalo breeding in the region. According to the survey results, it was realized that 75% of the buffalo breeding farmers have been doing this business as family breeding traditionally, 53.85 % of them as the main source of income and the rest as supplementary. The average animal number per farm is 12 heads, and the maximum number is 28 heads. Average daily milk yield of buffalos is 5-6 liters. One kg buffalo cream is produced from 5.5- 6 liters milk. The general target of buffalo breeding is to produce buffalo cream. In producing buffalo cream, traditional methods are used. The average price of a kilo of buffalo cream is about 10.9-12.13 Euros. The numbers of buffalos and buffalo breeding have been decreasing in Aydin Province day by day, as well as in Turkey. At the end of this study, it was determined that the main source of income in the farms doing buffalo breeding for long years had been the buffalo cream. The only markets of this buffalo cream were seen to be the few Turkish pizza restaurants in the environment.listelement.badge.dso-type Item , listelement.badge.access-status Open Access , Amelioration of the karakul sheep race in different areas and countries of the world(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2018) Buzu, I.The purpose of this paper was the comparative appreciation of the historiography of the Karakul race improvement in various areas and countries of the world. It was found that, Karakul sheep are concentrated, harvested and exploited in countries and regions that have vast natural pasture lands, even impoverished (semi-desert and desert from Central Asia, Africa), but expanded with a climate that allows them to be maintained throughout the calendar year to grazing, without costly shelters. In these countries and regions, Karakul sheep are breding not only to meet the urgent needs of the rural population, but also to get income from the sale of skins at international fur auctions. In Germany and Austria, the Karakul sheep were raising both for breeding and crossbreeding with other races, as well as for pure race for breeding material. On the basis of scientific research, was elaborated Karakul sheep origin and the formalistic view of the influence of the environment on the spinning of the fibers and the formation of the loop was combated. Have been identified the most compatible races (Somali) for crossing with Karakul, on the basis of which the idea of creating new Karakul sheep populations in Southwest Africa (Namibia) was created by crosses of transformation of sheep from breeds local. In Namibia, they were created some new entarasias of sheep Karakul with smooth curls, moire and smooth bark with short fibers. The skins of these types have soon conquered the world market of similar fur. In Ukraine, at the Institute for Scientific Research for the Steppe area, between 1935-1970 years was created, by crossing the Karakul with Romanov a new type of prolific Karakul. In Romania, at SCPCO Popauti, Botosani, a new type of Karakul sheep was created by crossing the Turcana sheep with the pure race Karakul rams, creating new lines and new populations with varieties of colors, gray, brown and white. In the former USSR, with the help of researchers from the United States Institute for Scientific Research for Karakulture (Samarkand), through the selection and the increase of sheep pure Karakul sheep were created a large number of sheep intakes such as: Gray of Buhara, Gray of Surhandaria, Gray Karakalpakia, as well as elite, black: Karakum, Mubarek, Nişan, Kenimeh etc; of greyish colour Nurata, Guzar, Cabadian etc; Gray Color: Kazalkum, Navoi, Talimarjan, etc. After the collapse of the USSR, the independent Central Asian countries continued to improve the Karakul sheep race, in which have been created a series of new type of Karakul sheep (15 in number) with specific productivity for skins, including Uzbekistan - 7 types, Kazakhstan - 4 types, Turkmenistan - 2 types, Tajikistan - 1 type, Kalmâkia - 1 type. All new type of Karakul sheep, created in Central Asian countries, South Africa and Europe, have unilateral production - high quality newborn lambs with different types of valuable curls and original colors. Neither one of new types of Karakul sheep produced in these countries (except Romania) has not aproached the issue of improving milk and meat skills as they are not specific to the Karakul race breeding in the home regionslistelement.badge.dso-type Item , listelement.badge.access-status Open Access , Analysis of reproductive parameters in Arabian Shagya mares from Rădăuţi studfarm(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2018) Pânzaru, Claudia; Gîlcă, Ioan; Doliş, Marius; Radu-Rusu, Răzvan-MihailThe study based on 50 Shagya Arabian mares (Mersuch, El-Sbaa, Koheilan, Shagya, Siglavy Bagdady, Dahoman, Hadban and Gazal bloodlines), reared in Rădăuţi studfarm, regarding gestation, foaling-interval and natality, had the purpose to follow the dynamics of these parameters between 2002-2016 years. The extremes of gestation length were found in Dahoman bloodline (300 and 366 days), while the only significant difference (p<0.05) occurred between Shagya and Dahoman bloodlines. The mare gestation lasts between 310-340 days; in the studied population, the average gestation length was found toward the upper limit (339.5 days). Foaling-interval (FI) registered minimal values in Dahoman line (284 days) and maximal ones in El-Sbaa lines (1424 days), whereas no significant differences occurred. FI standard is comprised between 337-338 days, if the mare is mated 8 days post-partum. In the studied population, the average FI was 472.7 days, indicating a intense difference against the species standard, probably due to the reproduction management practices. The natality had the lowest value in Shagya bloodline (54.90%) and the highest one in Mersuch (72.22%). The average natality in mares is 60% while 65.04% was the average calculated for the 50 Shagya Arabian mares. Consequently, we suggest optimizing the horses’ reproductive activity in Rădăuţi studfarm, decreasing thus foaling-interval value and favoring in mating those mares whose gestation duration is closer to the species average value.listelement.badge.dso-type Item , listelement.badge.access-status Open Access , Identification of milk composition and proteins polymorphism correlated with cheese quality, to select the best carpatina goats(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2018) Lazăr, Cristina; Pelmus, Rodica; Ghiţă, Elena; Rotar, M.C.The purpose of this study was to identify the proteins polymorphism in Carpatina goat in order to select the best individuals which exhibit the most increased polymorphism for αs1-caseins. Milk composition was analysed for fat (5.08%) and protein (4.14%). Protein percentage didn’t display high variability and ranged between 4.82% and 3.22%. SDS-PAGE analysis revealed, after electrophoresis, five protein fractions in milk samples: αs1, β, k-CN, and β-LG, and α-LA. Different expressions of the same type of protein fraction were discovered by densitometry analysis for each investigated goat. The casein group, composed by three fractions α s1-, β- and k-casein (17.5%, 48.8%, 10.9%), shows in fact that they are 77.2% of the total milk protein and 22.8% are albumins, similar with other studies for goats. Three levels of expression were recorded for each milk protein in every milk sample: 19.04% of the goats manifested strong expression for α s1-CN and medium and low expression for 57.15% and 23.81% of it. In case of the β-LG, strong expression level was found for 38.09% of the goats and medium and low expression level for 47.62% and 14.09%, respectively. Further investigations will be necessary to confirm the results by PCR-RFLP analysis to identify Carpatina goat caseins polymorphism with the genetic variants for each protein locus. This will allow keeping for reproduction the most suitable animals with strong genetic expression and high content in caseins very well correlated with milk quality and quantity.listelement.badge.dso-type Item , listelement.badge.access-status Open Access , Assessment ofabilities for meat production for half-breeds resulting from the crossing of Awassi and Tigaie sheep(“Ion Ionescu de la Brad” University of Agricultural Sciences and Veterinary Medicine, Iaşi, 2018) Pascal, Constantin; Nechifor, I.; Cristian, C.; Florea, M.The purpose of the research was to carry out a real analysis of the capabilities on which meat production depends on two lots consisting of individuals of the Tigaie breed and respectively of the half-breed individuals resulting from the systematic crossing of the local Tigaie sheep with Awassi rams. The importance of research results from the fact that the half-breed population considered is in the seventh generation and is reproductively closed to fix the characters on which milk production depends. Since, in expressing the efficiency of the management system applied in sheep breeding, milk and meat contribute to about 82% of the achieved results, can also be a mark in the development of an improvement program that includes in its objectives also meat production. The biologic material subjected to fattening and subsequently to planned assessments, was made up of the youth of this year, males and females, and the fattening applied was semi intensive and had a total duration of 140 days with the following technological phases: accommodation (10 days), breeding and fattening (90 days) and finishing (40 days). The statistical data processing revealed that the difference between the two lots was insignificant for the carcass weight, significant for p≤0.05 for live weight and distinctly significant for p≥0.01 for the average yields at slaughter. When assessing the quality of the carcases, it was found that at the group formed from fattened youth belonging to the new sheep population (AWxTi) at a higher proportion were satisfied the requirements for the R class, while 60.66% of the Tigaie lambs expressed the requirements for the same class and only about 20% fulfilled the requirements for the U class. Based on the data obtained, it can be stated that in order to fix the final morphological type of the new sheep population it is necessary to include among the breeding selection objectives the characters on which meat production depends.
