There are presented the results of studies of the exterior and economically useful characteristics of first calf heifers of the local generation of the Holstein breed, bred in a herd of Joint-Stock Company “Aydyn”, Komrat, Administrative and Territorial Unit Gagauzia, Republic of Moldova. The bone index in comparison with the standard turned out to be on average 8.3% lower, which is due to the high height at the withers of Holstein cows. Comparative analysis of milk productivity of daughters of various bulls showed that milk yield for 305 days of lactation of daughters of bull Forms 999 is 155 kg more milk than that of daughters of bull Kiperush 79. Realization of the genetic potential of first-calf heifers of local selection was at the level of 91.4-92.1% of the productivity of full-aged cows, with a fat content of 3.82- 3.89%. The relationship between the milk yield and the percentage of fat in the milk of the daughters of the analyzed bulls was in a positive correlation from the weak (+0.034, daughter of Kiperush 79), to moderate (+0.369, daughter of Forms 999).

A comparative analysis on 36 metric, 7 meristic features was performed and 7 morphometric indices were calculated in seven-year-old male and female hybrids (F1 Acipenser baerii x Acipenser gueldenstaedtii) grown under the same conditions on a super-intensive cage farm. The antiventral (P<0.05) and pecto-ventral (P<0.01) distance are bigger in female fish. Their head, compared to males, is wider, higher in the area above the eye and has a relatively larger space behind the eye (P<0.05). Female fish have a relatively larger eye diameter (P<0.01), wider mouth (P<0.001) and snout (P<0.001), higher dorsal (P<0.05) and anal, (P<0.05) and longer pectoral (P<0.001) and abdominal (P<0.05) fin. Male hybrids have a higher body relative to total length (P<0.01), a higher caudal stalk (P<0.05), and a longer anal fin (P<0.01). Their head has more massive and long snout (P<0.001), a bigger distance from the snout end to the mouth (P<0.001) and a greater width of the lower lip brake (P<0.05). The ratio of lower lip brake to the mouth length was higher (P<0.001) in male fish. The values of the high backed index (P<0.01) and the fatness index, including the body girth (P<0.05) in female fish are higher.

The state of genetic balance in one or more loci, no matter if it concerns the loci involved in genetic determinism of quality or quantity traits, describes an ideal state, being influenced by natural selection, non-random mating, gene flow and genetic drift. The Hardy-Weinberg equilibrium trial presents a significant importance because any deviation from it reveals the existence of some disturbing, restrictive factors. Thus, in this direction, there were researched four swine statistical livestock, taking into account the aggregate genotype derived from prealbumins, transferrins and serum amylases. The significant distribution of the individuals which present the genotypical combination PaBPaB/TfBTfB/AmBAmB -(Landrace - 39.5%; Large White - 23.7%; Synthetic Breed P 2000 - 22.7%; Synthetic 345 - 31.9%) was characteristic of the four researched samples. Out of the 27 possible combinations in the three loci, there weren’t identified individuals with the aggregate genotypes in any sample: PaAPaA/TfATfA/AmAAmA; PaAPaA/TfATfA/AmAAmB; PaAPaA/TfATfB/AmAAmA; PaAPaA/TfBTfB/AmAAmA; PaAPaB/TfATfA/AmAAmA; PaAPaB/TfATfB/ AmAAmA. In order to estimate the balance state, it was calculated the determinant of the gamete matrix. The result of the genetic state Hardy Weinberg trial, simultaneously for the three loci (g11 g33 g17 g39 = g31 g13 g37 g19), emphasized the fact that none of the livestock is in genetic balance, as it follows: Landrace (0.0000215 ≠ 0.0000067), Large White (0.000039 ≠ 0.000041), Synthetic Breed P 2000 (0.000055 ≠ 0.000025), Synthetic Breed 345 (0.000004 ≠ 0.000030). This shortage of balance was caused by an indirect selection, with a higher coefficient of some genotypic combinations in comparison with the others.

Current research is a part of a research program aimed to study the relationship between morphology and physiological status of turkey pineal gland in relation to the degree of somatic development. Research is carried out at S.C. Galli Gallo Codlea, which is the only unit in Romania for breeding and slaughter of turkeys. The measurements were performed on an important livestock specie for modern husbandry industry, namely turkey, the expansion of this area being useful for providing knowledge on the relationship between technology growth for modulation of microclimate parameters and growth performance. Were followed hematological and biochemical blood parameters,with the purpose of providing a parallel between turkey (Meleagris gallopavo-gallopavo) and chicken (Gallus gallus).

The knowledge of haematological and urine biomarkers is useful to diagnose various metabolic and pathological disorders, which have a negative impact on the overall performances of dairy species. The aim of this study was to investigate the haematological and urine parameters in lactating dairy cows comparative with lactating buffaloes. The study was carried out on sixty-eight Romanian Black and Spotted cattle and on fifty Romanian buffalo. The obtained values for hemoglobin concentration (HGB), hematocrit percentage (HCT), white blood cells count (WBC), lymphocytes percentage (LY), monocytes percentage (MO), and neutrophil percentage (NE), varied significantly (p<0.01) between cows and buffaloes. For other haematological indices, such as mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC), statistical differences were recorded. Urine examination of cows and buffaloes showed that all the parameters studied were within the normal physiological limits, with minor fluctuations for protein level (30 mg/dl). The obtained results could serve as baseline information for comparison in conditions of nutrient deficiency, physiology and health status of dairy herd’s.

Vegetable oils are a good source of high quality lipids, ω-3 and ω-6 acids, vitamin E and other biologic active components recommended to be included in a healthy diet. Based on the type of oil seeds and processing technology, the composition and physico-chemical proprieties of oils differs. For the research, we used samples of sunflower oil (pressed and refined), soybean oil, olive oils and nuts oil, which were characterized accordingly to standards, based on certain characteristics (phosphatides level, acidity index, peroxide index, saponification index, refraction index, neutralization index). The results have shown the influence of processing on the final characteristics of oils and also helped to draft and understand the recommendation regarding their storage.

Given the performances of the bees of the native breed Apis melifera and those of the Buckfast hybrid, it was desired to find out what are the performances of some products obtained from the crossing of the two populations. The study was conducted between 15.04.2017 and 10.06.2018 at the acacia harvest, where four families of different breeds were selected, respectively 2 families from the native breed Apis melifera carpatica (A1 and A2) and 2 families from the Buckfast hybrid. (B1 and B2). The families taken in the study were chosen from the hive depending on the degree of development. The characters pursued for the obtained products were: the quantity of honey harvested, the gentleness, the instinct of roasting, the building of artificial honeycombs as well as the amount of pollen harvested in the ascending and descending population during 2017 and 2018. Regarding the amount of pollen harvested in 10 days, the B2 family recorded 2.6 kg, for honey production, the harvest is significant in favor of the daughters of the Buckfast hybrid.

The purpose of the research was to determine comparatively the results of slaughter separately by sex, in the case of two populations of quails (meat and mixed), at the age of 6 weeks. The average weight of the eviscerated carcass for meat quails was 205.00 ± 8.82 g/head in females, while in mixed eggs-meat female quails it was 135.20 ± 3.29 g/head (34.05% higher as in females in the mixed population) and 173.80 ± 6.37 g/head in males of the meat population (26.24% higher than in males of the mixed population, 128.20 ± 3.98 g/head). Studied Jumbo meat quails can be used with good results in meat production, chickens being raised for meat production, while quails from the Baloteşti mixed egg population can also be used in the direction of meat production, if desired of smaller carcasses compared to those of meat quails. For both populations, the breeding for meat is conditioned by a high performing breeding lot and without directing the females to egg production.

The purpose of the present paper was to investigate the degree of conformity of the flowers of some honey crops (rape, peas, maize) regarding pesticide residues, for the practice of organic beekeeping. Scientific research was carried out on the content of pesticide residues in flowers taken from industrial lands, suspected of contamination with pesticides. The results of the research demonstrate that, out of the 62 pesticides tested in the rape flower samples, detectable concentrations of residues were recorded in only 5 pesticides, which constitutes 8.1%. It has been found that rapeseed flowers are heavily polluted with the residues of the Glyphosate pesticide, in a concentration of 0.1772 mg/kg, which exceeds the maximum admissible limits, according to EU and MD standards, by 77.2%. In peas flowers, there were detectable concentrations of residues in only 7 pesticides, which constitutes 11.3%. The peas flowers in the researched industrial land were slightly polluted with the residues of the Glyphosate pesticide, in a concentration of 0.1088 mg/kg, which exceeds the maximum admissible limits, according to EU and MD norms, by 8.8%. In the maize flower samples, of the 62 pesticides tested, residues were detected in concentrations detectable only at 9 pesticides, which constitutes 14.5%. It was found that the maize flowers in the industrial land were heavily polluted with the residues of the neonicotinoid insecticide Thiametoxam at a concentration of 0.0178 mg/kg, which exceeds the maximum admissible limits, according to EU and MD standards, by 78.0%. Glyphosate residues in maize flowers were detected at hazardous (at the limit) concentrations of 0.0962 mg/kg, compared to the maximum admissible limits of 0.1 mg/kg. Therefore, the sites researched with rapeseed, peas and maize plantations are not conformity for organic beekeeping, because the flowers of these crops are polluted with residues of dangerous pesticides, banned by the EU, which can affect the health of bees and inoffensiveness bee products.

The paper aimed to present the situation of the mountain area in Romania between 2017 and 2019. This paper is based on statistical data provided by the National Sanitary-Veterinary Authority and for Food Safety and also by the National Institute of Statistics. These were processed within the National Agency of the Mountain Area in the following indicators: number of counties with mountain area, number of Administrative-Territorial Units in the mountain area, number of inhabitants in the mountain area, total area of the mountain area (km2), area of pastures and meadows in the mountain area (ha), the number of animals in the mountain area (cattle, sheep, goats, pigs). Compared with 2017, the number of animals, in 2019, registered significant decreases, which leads to negative effects on maintenance of permanent grassland areas in the mountain area, milk and meat production from animals, milk processing activities, respectively meat and, implicitly, reduced possibilities of developing farms in the mountain area.
