The study was conducted for the first time on rams of the Karakul Moldavian breed. As an antioxidant, two versions of the ZooBior preparation were used, which contains: BioR, spirulina, zinc and selenium. The preparation was given to rams in teenium for 50 days at the rate of 5 g/head/day. Studies have shown that the ZooBior drug increased the volume of ejaculate by 0.4 ml in the second experimental group, the motility by 11%, the concentration of sperm in the sperm by 0.1 billion/ml and the total number of sperm in the ejaculate with rectilinear movements. With 6.5%, the data are reliable compared with the indicators found at the beginning of the experiment. There have also been some fluctuations in sperm kinetics. Semen advancement rate increased in the experimental groups, but the data are not significant.

This research paper consisted in carrying out a study that elucidates how the quality of cow’s milk varies depending on the time of lactation initiation (calendar month in which the cows gives birth and the lactation starts). Thus, there were examined milk samples from two groups of cows that gave birth in different seasons (autumn and spring). The determinations concerned were the following: the percentage of protein, the percentage of lactose and the fat percentage in milk. After analyzing the results, compared to the cows that gave birth in autumn, we observed that the percentage of protein increased in the milk from the cows that gave birth in spring, whereas the percentage of fat decreased. The percentage of lactose varied within the similar limits for both experimental groups.

The present paper aims to analyze the quantitative performances and aptitudes in the direction of milk production achieved by the Bălă ecotype of the Tsurcana breed. The quantitative analysis was performed on a sample of female sheep from the Bălă ecotype, selected from farms in the northwest region of Romania, respectively the Maramureș and Bistrița-Năsăud areas. In order to carry out the analysis, statistical data were extracted from the genealogical register, following indicators such as total milked milk production, lactation period, suckling period duration, milking period duration. The results of this study highlight that the average milk production calculated for the period 2016-2019 and for the selected sheep herd is 82 kg milk, according to the standard of the Tsurcana breed, using the t-statistic test for the selected sample. Thus, the data show a difference of approximately 12 kg of milk between the average milk production of the selected sheep from the Bălă ecotype and the average milk production of the Tsurcana breed, a difference which is statistically insignificant. Finally, we can see that the Bălă ecotype has a good performance in milk production within the breed standard.

The economic efficiency of dairy farms is influenced by many factors and depends on their management. Some research shows that the conventional milking system (CMS) is more cost effective than the automatic milking system (AMS). The data collected for carrying out this research come from the accounting records of the dairy cow farms (from 2018). From the current study it appears that the capital expenditures were significantly higher in the case of farms with AMS than in the case of farms with CMS and the total incomes for the farms with AMS and CMS were 1745.2 RON/t milk and respectively 1785 RON/t milk, and the net productions were 1117.61 RON/t milk for farms with AMS and 1155.14 RON/t milk for farms with CMS. In terms of personnel costs, they are higher in farms with CMS, 512.3 RON/t milk, whereas in AMS farms staff costs do not exceed 484.1 RON/t milk. Following the observations, the two milking systems have similar profitability in the market conditions of the Romanian economy.

Pigeon breeding is an activity with tradition in Romania, because their meat is a very valuable food product. The aim of the current paper is to investigate the effect of a dietary supplement (containing trace elements, vitamins and amino acids) used by pigeon fanciers for growing pigeon chicks. Another goal is to investigate whether the dietary supplement has effects on the erythrogram of pigeon chicks. The obtained results showed that the dietary supplement, due to its components, determined an intensification of the growth rate of pigeon chicks, so it can be used successfully for this purpose. Regarding the erythrogram, there were observed significant increases in the number of erythrocytes and hemoglobin (which demonstrates an intensification of erythropoiesis) and decreases in MCV and MCH (which demonstrates that the intensification of erythropoiesis is accompanied by the installation of microcytosis and hypochromia).

The purpose of this paper is to make an analysis of the evolution of the Aberdeen Angus breed in Romania. This research paper desire to be a first response to the many questions about accommodation, advantages, disadvantages, bio-acclimatization and profitability of the Aberdeen Angus cattle breed at national level, compared with the country of origin Scotland and with the countries with great success in raising this breed. The first embryo transfer was performed in 2000 and at the end of 2008 there took place the first cattle import of 120 heifers Aberdeen Angus breed from Germany. Now in 2019 we have in the Aberdeen Angus Romanian Herdbook 45.000 cattle in all area of Romania. During this research we noticed that the Aberdeen Angus breed is accommodating well in the Romanian pedoclimate conditions.

Research on growth performance, weight, daily average enrichment recorded on hybrids of the native Tzurcana breed with the two paternal breeds of French Vendeen and White of Central Massif were the objective of study and analysis of this paper. The study was conducted from the spring of 2018 on the sheep private farm of the County - Olt on the 180 females sheep, of which 30 were of the Vendeen breed to track the performance of the pure breed in our country. The other 100 females were cross with the two races to obtain F1 hybrids with Vendeen and BMC, and 50 were considered a control group of the pure Tzurcana native breed. All animals were subjected to control of calf weight W0 at 30 days of age W1 at 70 days W2 and W3 at 98 days of age. The results high lighted both the net superiority of the meat and the adaptability of the Vendeen paternal breed to the semi-intensive exploitation system towards Tzurcana; the prolificity was 140% versus 103% and a net average net increase of 72 g/day in females and 94 g/day in males in the first month of 90 g/day in both sexes in the 2nd month of growth respectively 91 g/day in females and 87g/day in males in the third month of growth. It is evident both the superiority of the pure paternal breed and the crossbreed obtained from the breeds with the breeds mentioned, regarding the assimilation-conversion capacity and the different growth rate in stages compared to the native breed, but between the crossbreeds the results are relatively similar to the small difference.

The aim of the research was to evaluate the productive performance of Saanen goats by applying an optimizing modern food rations formula. The experiments were realized between 1.05-2015-2.11.2016 in 2 farms of Constanta County, Romania. Experiments were conducted on two groups of 30 females in full lactation with an average weight of 55 kg, breeding in anintensive system(Group I) and semi-intensive system (Group II). The experiment lasted 130 days; during this period the milk production was recorded and samples were taken monthly for analysis, in particular the concentration of fatty acids and food consumption. Milk samples were processed by gas chromatography.Between the two groups at the same time changes in fatty acids were recorded for significantly increasing concentrations of monounsaturated fatty acids (MUFA-28.94 g FAME / 100 g fat) and polyunsaturated fatty acids (PUFA-4.86 g FAME / 100 g), as well as an improvement of the Ω3: Ω6 ratio to the second group (20.66). In conclusion the breeding system, energetic and protein level of food ratio was influenced the milk production and the fatty acids composition
