These are the results of studies on the assessment of the exterior of first-calf heifers of Holstein breed under the conditions of the Republic of Moldova. The aim of the presented scientific paper is the study of exterior features and morphological and functional indicators of the udder of Holstein breed in the herd of Holstein cattle of the breed of LLC "DokSanCom", v. Tomay, ATU Gagauzia. Exterior features were studied at 91 of first-calf heifers. As a result of the research, it was established that the first-calf heifers of Holstein breed were well-defined type of dairy cattle, which is confirmed by their proportional body shape, the development of the middle part of the trunk, and strong bone structure. The first-calf heifers in the herd of SLL "DokSanCom" were quite tall – 139.1 cm height at the withers and 146.6 cm – in the sacrum. The slanting length of the trunk is 198 cm on average. The prolixity index was 117.0%, which is by 2.5% less than compared to the standard for breeds of dairy direction of productivity. A compact physique with a consistency index of 122.1% characterizes the estimated the first-calf heifers. Measurements of the udder along the girth, length and width were on the average 137.1; 45.9 and 32.6 cm respectively.

Water is one of the natural resources most widespread on Earth, between living organisms and water being an indispensable link. The aim of this research was to assess the water quality of the Stânca-Costeşti accumulation based on the results obtained from the determination of physical- chemical parameters and toxic pollutants. Stânca-Costeşti accumulation is situated on the border between Romania and Moldova in Botosani County. The elements determined for each sample related to the studied section are represented by: pH, dissolved oxygen, biochemical oxygen demand (B.O.D.), nitrite, nitrate, chlorides, sulphates, cadmium, nickel, lead, zinc, copper and chromium. In order to establish the values of determined elements were applied standardized analytical methods. The average concentrations of analyzed heavy metals were below maximum permissible concentration for Ist class of quality. As a general conclusion based on these results, we can say that water from Stânca-Costeşti accumulation fall within the IInd class of quality in terms of the oxygen and in the Ist class of quality in terms of nutrients and heavy metals.

The aim of this work was to study the total phenolics content and antibacterial activity of bee pollen samples from different sources. Total polyphenols content was quantified according to the Folin-Ciocâlteu spectrophotometric method using GA as standard and the results were expressed in terms of mg GAE/g pollen. Furthermore, the antibacterial activity of bee pollen samples from different sources were collected and investigated against multiple bacterial strains, as follows: five gram-positive Staphylococcus aureus ATCC 6538P, Bacillus cereus ATCC14579, Bacillus laterosporus 6932, Paenibacillus larvae 9820 and Paenibacillus alvei 13253, and four gram-negative Escherichia coli ATCC 10536, Pseudomonas aeruginosa ATCC 27853, Salmonella enteritidis ATCC 13076, Salmonella typhi ATCC 14028 and the yeast Candida albicans ATCC 90028. The samples with predominant pollen in Brassicaceae and Rosaceae possessed high levels of polyphenols content, whereas the samples predominant in Fabaceae showed lower levels of polyphenols. Regarding the antibacterial activity, our results revealed that most of the strains were inhibited by the ½ and ¼ dilutions. The gram-negative bacteria and the yeast Candida albicans proved to be resistant to all bee pollen methanolic extracts. Our results showed that bee pollen samples have strong antibacterial activity against gram-positive bacteria.

Research on various avian species has shown that supplementation of diets with various mineral elements can have favourable effects on production indices, production quality and bird health. In particular, chromium has proven to be an essential mineral, active biologically as a component of glucose tolerance factor, which enhances tissue sensitivity to insulin and glucose utilization. Clinical trials conducted in human patients diagnosed with Type II diabetes along with studies on production animals have led to the conclusion that chromium is beneficial to animals and people undergoing physical or metabolic stress. A brief analysis of chromium supplementation of avian species feed revealed more results of chromium supplementation in broiler nutrition compared to laying hens, which is why the present review was conducted to evaluate the results of using different chromium sources in laying hens. Summarizing the information from the scientific literature on the use of chromium in laying hens nutrition can highlight whether this nutritional strategy is useful or not for laying hens farmers.

The objective of the work is to carry out a bibliographic study on the biological value of milk from different animal species (cow, buffalo, goat, sheep, donkey). The quality of the milk and its composition varies depending on the breed, diet, feeding practices, management system, lactation stage and animal health. Milk and products obtained from it contain most of the nutrients needed by the human body, with a high biological value. Studies have shown that the milk with the highest fat content is sheep’s milk, followed by buffalo milk, cow’s milk, goat’s milk and donkey’s milk. In addition to the genetic variation between animal breeds, feeding fodder with a fat and fiber content can lead to an increase in the fat content of milk.

The features of protein nutrition and protein requirements of honey bees must be taken into account, given that bees are social insects, and should be examined at three levels: bee colony nutrition; adult bee nutrition; larva nutrition, since disturbances in protein nutrition at the previous stages of development affect the subsequent stages and vice versa. The content of free amino acids in the main protein sources - pollen, bee bread royal jelly, as well as the content of amino acids in some bee protein additives and in whey was examined. The quality of the natural bee protein food, must be evaluated, depends on the essential amino acid content, especially leucine, isoleucine and valine. When replacing the natural protein food of bee colonies, with other protein additives and substitutes, it is necessary to consider the protein and essential amino content, and also the lysine/arginine ratio, as an index of the quality of the protein and the protein additive respectively.

Leachate is a liquid that occurs as a result of mixing rainwater runoff with rubbish that has decayed and contains very fine suspended substances and pathogenic microbes. Leachate can cause potential contamination for both surface and groundwater. In this study biodegradation of leachate by microorganisms was carried out to reduce the content of organic and harmful inorganic substances. The purpose of this study was to evaluate the potential biodegradation of bacterial isolates isolated from landfill leachate. The method used in this study is an experimental method with three repetitions. The parameters observed included the levels of Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solid (TSS) and ammonia, for 14 days the biodegradation process. Data from the research results were analyzed using Variety Analysis (ANOVA) followed by Duncan's multiple distance test. The results showed that a consortium of Bacillus subtilis, Bacillus licheniformis, Bacillus pumilus, Pseudomonas putida, Nitrobacter and Nitrosomonas (K3) capable of reducing BOD levels by 68%, reducing COD levels by 89%, TSS by 71%, and Ammonia by 92 %, reducing 90 % of chrome and 90 % of lead.

The biologically active preparation under the symbolic name "Bison" was administered to pregnant cows for a period of 150 days (60 days before calving and 90 days after calving) 20 ml/head/day. As a result of the research it was found that the cows in the experimental group had no complications in calving, the first estrus manifested after 27.3 days, each cow was seeded as a result in the first estrus, spending only 2 doses of frozen semen, while in the cows from the control group, which did not receive the preparation "Bison", the first estrus manifested after 36.2 days, each cow was inoculated 1.75 times, spending on average 3.5 doses of M.S.C. for a gestation of a cow. Fertility was 2 times lower in the control group (50%) than in the experimental group (100%). Thus, the administration of the nominated preparation, cows in the last 2 months of gestation and the first 3 months after calving, in the amount of 20 ml/head/day, led to a decrease in the number of artificial inseminations for a gestation by 0.75 units, to a decrease in semen costs by 1.5 doses/cow, and to an increase in fertility by 50%.

Body Condition Score (B.C.S.) is a good indicator for estimating the reserves, especially of energy, that the dairy cows have to support milk production. In general, the values that this indicator can take vary between 1 and 5 with the evolution of lactation over time, but also from one cow to another. Good dairy cows have difficulties maintaining B.C.S. at an optimal level, especially during the first and second lactation period, since the ingestion capacity of nutrients they have is exceeded by the body's need for milk production. For this reason, the negative energy balance is installed. In order to cope with this period, animals dispose their body fat, thus setting up the negative energy balance, a phenomenon that significantly affects certain zootechnical efficiency parameters such as productive longevity, lactation duration, calving interval, etc. Nutritionists can mitigate this impact by optimizing ratios also taking into consideration this parameter. The present paper aims to determine the correlation between the rank and age of lactation with the value of B.C.S.
