The paper presents results of assessing black-and-white bulls by the quality of the offspring with application of different methods. The evaluation of bulls was carried out with application of the “daughter-mother” method in the conditions of Volzhsky Research Institute of Hydraulic Engineering and Land Reclamation. The valuation showed that the bulls Aist 7 and Muscat 8 increased milk yield of daughters, in comparison with mothers, by 951 and 486 kg, or by 26.7 and 12.9%. The rest of the servicing bulls reduced milk yield of the offspring by 46 - 1019 kg (1.1 - 24.7%). When assessing the bulls using the “daughterpeer” method, the highest milk productivity was shown by the descendants of Sazan 25 and Aist 7 of Vis Back Ideal line, which surpassed their peers in milk yield by 273 and 419 kg, or by 3.8 and 5.7%, respectively. The producers Snop 57 (his 17 daughters had average milk yield of 4224 kg for the first lactation with milk fat of 3.80%) and Muscat 8 (with an average milk yield of daughters of 4254 kg , milk fat - 3.83%) are also of significant value for the breeding work of this farm. According to the assessment results, the producer Aist 7 was assigned to the breeding category of A1 of milk yield improvers. Bulls Sazan 25 and Muscat 8 are also rated as daughters’ milk yield improvers and are categorized as A2 and A3. All bulls evaluated by comparing daughters to the breed standards are improvers of daughters’ milk yield (+ 454-1860 kg).

Basic Approaches

The relevance of research. Currently the methodological base for assessing the breeding qualities of bulls-producers of dairy and milk-meat breeds by the quality of offspring is carried out in accordance with the Instruction approved by the MA of the Republic of Kazakhstan in 2007. The principle of assessment, set out in the Instruction, is to compare the phenotypic indicators of the offspring with each other according to the principle of “peer daughter”. Although this document was approved already in the XXI century, nevertheless the basic approaches, which were put the basis, were developed in the first half of the last century and currently do not correspond to modern scientific principles. At the same time the world leaders in the field of breeding in dairy cattle breeding have been successfully using the BLUP method in breeding practice to assess the breeding qualities of animals for decades. This principle of assessing the breeding value of bulls is the most theoretically grounded and allows you to obtain results comparable to each other. Therefore the development and optimization of the equations of mixed BLUP models is extremely relevant for the conditions of the Republic of Kazakhstan from both scientific and practical points of view.Material and research methods. The material of the research was the data on the phenotypic indicators of the signs of milk productivity of first-calf cows of the Holstein black-and-white breed obtained from the republican database of the Republic of Kazakhstan for 2016-2017. As a criterion for choosing the best equation the residual variance values of each model under study were used.Results: when improving the method for assessing bulls-sires of the Holstein black-and-white breed according to the quality of offspring, out of the four studied equations of the mixed BLUP model one equation was optimized to assess the breeding qualities of the sires. In principle, to assess the breeding qualities of producers by the quality of offspring it is possible to use any of the models under consideration, since the established differences for all analyzed characteristics of milk productivity are insignificant (no more than 6%)

AbstractHeavy metals can selectively accumulate in certain organs and remain in them for a long time. As a result, the accumulation of metal in one or another organ may cause strongest intoxication of the animal. The purpose of the research is to study the morphological and biochemical composition of the blood of young cattle of different breeds of the dairy and dairy-and-beef direction of productivity fed in the technogenic zone in the RNO-Alania diets with a high content of heavy metals. According to the principle of analogues, taking into account the breed, origin, age, sex and body weight, 4 groups of 10 animals each of different breed were formed: Group I - black and white, Group II - Danish Red, Group III - Swiss, and Group IV - Simmental. The experimental material was statistically processed using the Microsoft Excel software for mathematical analysis. With a tendency of unreliable differences in morphological indices of blood, in diminishing numbers of erythrocytes and hemoglobin, the test breeds should be arranged in the following order: Simmental → Swiss → Red Danish → Black and White. At the same time, as compared to the animals of the black-and-white breed, the young cattle of the Simmental breed showed the best level of intermediate metabolism, which resulted in an increase in total protein and sugar in the blood, which indicates an improvement in their protein and energy metabolism; an increase in the content of albumin in the liquid internal medium and γ-globulins;an increase inconcentration oftotal lipids in serum, respectively, while reducing the level of cholesterol, which indicates an improvement fat metabolism in animals; a significant (P <0.05) decrease in blood saturation with cadmium, lead and zinc, respectively, by 26.8, 48.8 and 30.6%. The highest content of these elements was noted in the wool, then in decreasing order: in bone tissue → liver → muscle tissue → lungs → kidneys. Moreover, between the level of heavy metals in muscles, liver and lungs, on the one hand, and in the wool, bone tissue and kidneys, on the other hand, there was an inversely proportional relationship.

Проведена оценка по качеству потомства быков-производителей перспективных линий черно-пестрой и голштинской пород на маточном поголовье черно-пестрой породы методом «дочери—сверстницы», что позволило определить лучших племенных животных для планового закрепления в стаде. Результаты исследований показывают, что используемых производителей можно условно разделить на 3 группы: с высокой племенной ценностью (ПЦ) по удою (Набат 209, Кадр 1386, принадлежащих линии Аннас Адема 30587) и МДЖ (Фантик 1550, Валун 1771 — л. Аннас Адема 30587; Дорис 1060 — л. Р. Соверинга 198998 и Корнет 251 — л. Вис Бэк Айдиала 1013415); со средней (Фагот 58, Банкир 109, Корнет 251, Миксер 312 и Жест 1401 — л. Вис Бэк Айдиала 1013415; Девик 6200 — л. Р. Соверинга 198998; Дождь 1839, Зенит 5209 — л. Посейдона 239) и с незначительной ПЦ (Банкир 109, Валун 1771 и Каскад 1596 — л. Вис Бэк Айдиала 1013415, Аннас Адема 305874 и Танталуса 203, соответственно). Наиболее значимыми в племенном отношении как по удою, так и по жиру являются быки-производители черно-пестрой породы линий Аннас Адема 30587 и Посейдона 239 с ПЦ 271,56 и 274,16 кг, 0,02 и 0,05%, соответственно. С целью повышения продуктивных качеств крупного рогатого скота черно-пестрой породы желательно максимально использовать быков-производителей с высокой племенной ценностью, обеспечивающих реализацию генетического потенциала, проявившегося в их потомстве, путем целенаправленной селекционно-племенной работы со стадом. The assessment according to the quality of offspring from the seed bulls of the prospective lines belonging to black-and-white and Holstein cattle breeds was carried out on the pedigree stock of the black-and-white breed using the method of daughter-herdmate allowing to determine which breeding animals are the best for planned settlement in the herd. Research results show that the seed bulls used can be conditionally divided into 3 groups: with high breeding value (BV) in terms of milk yield (Nabat 209, Kadr 1386, belonging to Annas Adema 30587 line) and mJ (Fantik 1550, Valun 1771 — Annas Adema 30587 line; Doris 1060 — R. Sovering 198998 line, and Cornet 251 — Vis Back Ideal 1013415 line); with average (Fagot 58, Bankir 109, Cornet 251, Mixer 312, and Jest 1401 — Vis Back Ideal 1013415 line; Devik 6200 — R. Sovering 198998 line; Dozhd 1839, Zenit 5209 — Poseidon 239 line) and insignificant BV (Bankir 109, Valun 1771, and Cascad 1596 - Vis Back Ideal 1013415, Annas Adema 305874, and Tantalus 203 lines, accordingly). The most significant in breeding terms, both in milk yield and fat, are seed bulls of the black-and-white breed belonging to Annas Adema 30587 and Poseidon 239 lines with the BV of 271.56 and 274.16 kg, 0.02 and 0.05%, accordingly. Using seed bulls with high breeding value ensuring realization of genetic potential seen in their offspring by purposeful selection and breeding work with the herd is preferable for increasing the productive qualities of cattle belonging to black-and-white breed.

Effect On Growth

The purpose of the research was to make a comparative study of the use of enzymatic probiotics in the feeding of young cattle Black-and-White breed and to determine their effect on growth, development and metabolic processes. Under the conditions of the Amur region the use of enzymatic probiotics in the feeding of young cattle has been justified in two scientific and economic experiments. In physiological experiments the digestibility of nutrients in rations has been determined; the balance of nitrogen, calcium and phosphorus has been studied. As a result of the first scientific and economic experiment, a comparative study of the feeding of enzymatic probiotics Cellobacterin and Vitacell to calves has been carried out. It has been found that the inclusion of the enzymatic probiotic Vitacell in the rations of calves had a better effect on growth, digestibility and balance of nutrients as well as improved hematological parameters, bringing them to the physiological norms. In the second experiment the effect of the enzymatic probiotics Vitacell and Promilk on the dynamics of the live weight of young cattle, their growth, development and metabolic processes has been studied. It has been found that the enzymatic probiotic Vitacell had a better effect on growth, digestibility and nutrient balance compared to the probiotic Promilk. Thus, physiological, biochemical, zootechnical and economic research methods proved the feasibility of using probiotics in the rations of calves of Black-and-White breed, but the best results were obtained when using the probiotic Vitacell. The data of the production inspection confirmed the results obtained in scientific and economic experiments.
