Исследовано влияние генетических и паратипических факторов на повышение эффективности молочного скотоводства при внедрении интенсивной технологии производства молока в одном из предприятий Ярославской области. Установлено, что при межпородном скрещивании ярославских коров с голштинскими быками среднегодовой удой увеличился до 9577 кг молока (на 56,2), белковожировой коэффициент на 51,5. С вводом в эксплуатацию животноводческого комплекса на 2000 коров и комплектованием стада чистопородным скотом голштинской породы селекции Нидерландов и Восточной Германии генетический потенциал стада ещё более повысился. Средний удой коров за 305 дней лактации составил 10457 кг, что на 68 больше, чем при межпородном скрещивании выход молочного жира и белка на 63,4 выше. Возросла скороспелость молодняка, возраст первого отёла уменьшился на 112 дней, при укрупнении живой массы. В 7,7 раза увеличилась продажа племмолодняка, в том числе бычков для сети искусственного осеменения. Хозяйство получило статус племзавода по голштинской породе. Реализация генетического потенциала осуществлялась за счёт улучшения кормления коров по американской системе. Содержание коров круглогодовое стойловое, беспривязное, с формированием технологических групп по физиологическому состоянию и удоям. Доение трёхкратное на площадке Карусель, аппаратами фирмы Фемакс. Улучшилось воспроизводство стада: выход телят на 100 коров 83, сервиспериод сократился на 28 дней (до 124 дней). Валовый надой молока увеличился в 6,5 раза до 236048 ц в год, прибыль от реализации молока возросла в 7 раз, рентабельность его производства в 2018 году составила 26,66. От лучших коров получают удои свыше 15 тысяч кг молока за лактацию. По продуктивности стадо вышло на мировой уровень, и имеются перспективы для дальнейшего роста.The influence of genetic and paratypic factors on increasing the efficiency of dairy cattle breeding during the introduction of intensive milk production technology in one of the enterprises of the Yaroslavl region was researched into. It was established that with interbreeding of Yaroslavl cows with Holstein bulls the average annual milk yield increased to 9577 kg of milk (by 56.2), proteinfat ratio by 51.5. With the bringing cattlebreeding complex into operation for 2000 cows and the acquisition of a herd of purebred Holstein breed cattle of the Netherlands and East Germany selection the genetic potential of the herd has further increased. The average milk yield of cows for 305 days of lactation was 10457 kg which is 68 more than with interbreeding the yield of milk fat and protein is 63.4 higher. The earliness of young stock has increased, the age of the first calving has decreased by 112 days with the increase in live weight. The sale of pedigree young stock has increased by 7.7 times including bullcalves for the artificial insemination. The farm received the status of the stud farm on the Holstein breed. Realization of genetic potential was carried out by improving the feeding of cows according to the American system. The cows are yearround stable keeping, yard housing with the formation of technological groups according to the physiological state and milk yield. Threefold milking was at the site Carousel with the devices company Femax. Herd reproduction has improved: calves yield per 100 cows 83, service period reduced by 28 days (to 124 days). Gross milk yield has increased in 6.5 times up to 236048 c per year, the profit from the sale of milk has increased in 7 times, the profitability of its production in 2018 was 26.66. Milk yields over 15000 kg of milk per lactation are obtained from the best cows. By productivity the herd has reached the world level and there are prospects for further growth.

The characteristic of milk productivity of cows of Holstein and Simmental breeds in LLC “Sibirskaya Niva” in the Maslyaninsky district in the Novosibirsk region has been given. It has been revealed that under the natural and climatic environments of the Western Siberia, when creating favorable conditions for feeding and housing for cows of Holstein and Simmental breeds have sufficiently high milk productivity. It has been found that Holstein first-calf heifers surpassed their Simmental herdmates by 959 kg in milk yield for the first 305 days of lactation under the same conditions of housing and feeding, by 3,1 kg in daily milk yield, by 38,2 kg in milk fat yield, and by 28,3 kg in milk protein yield (P < 0,001). There were no statistically significant differences between animals of Holstein and Simmental breeds in terms of fat and protein content in milk, which amounted to 3,94 and 2,96 % in Holstein breed and 3,97 and 2,98 % in Simmental breed, respectively. Both breeds have shown high milk productivity during the first 3 lactations. Thus, the milk yield of Holstein cows for the first 3 lactation was 6475–9290 kg, Simmental cows it was 5516–7680 kg, fat content was 3,93–3,99 and 3,96–3,97 %, respectively. The protein content in the milk of cows of both breeds did not exceed 3,0 %. High variability has been found in milk yield, yield of milk fat and protein, the coefficient of milk content and duration of lactation, the lowest in the content of protein and fat in milk and live weight. The correlation coefficients between the fat and protein content in milk were generally positive, but did not exceed 0,28. Therefore, breeding in the herd of cows in LLC “Sibirskaya Niva” have to be conducted not only by fat content, but also by protein content in milk.

Abstract. Aim. The study of the influence of crossbriding on the growth and development of heifers and subsequent productive and reproductive qualities of cows on the first lactation. Methods. Using statistical methods, correlation analysis and ANOVA for evaluated genetic indicators of economic-valuable traits of dairy cattle. In particular was studied live weight of heifers from birth to 18 months, first insemination age and first fecundation age, live weight at fecundation, frequency of insemination, first calving age, days open, live weight at first lactation, milk yield for 305 days (kg), fat (%, kg) and protein (%, kg) in milk. Results. Relationship between productive indicators and the genotype of the animal is established. When assessing the strength of the influence of the factor «blood on the Holstein breed» it was found that the greatest impact can be traced at the age of 6 and 18 months, and is respectively 12.7 % and 17.1 %.The reproductive qualities of the first-calf cows decreased with the increase percent of blood in the Holstein breed. Evaluation of the impact of crossbreeding on milk production at first lactation has revealed significant strong influence on milk yield for 305 days of first lactation, and related signs the amount of milk fat and protein. According to qualitative indicators, the low influence of the Holstein blood fraction was found, while to a greater extent on the fat content than on the protein content in milk. Evaluation of phenotypic and genotypic correlations of milk yield and quality components of milk revealed average negative phenotypic and low negative genotypic correlation in all groups. The exception was in heifers of Yaroslavl breed with percent of Holstein blood less than 50 %, in which the relationship of yield x protein was positive. The relationship between milk yield and fat and protein content in milk has the opposite moderate character and strength. Practical significance. Studies was established that breeding of animals of Holstein and Yaroslavl breeds in one herd allows to receive an optimum ratio of milk production with optimal percentage fat and protein. For this herd among animals of the improved genotypes of the Yaroslavl breed, the use of genotypes with a percent of blood in the Holstein breed from 75.1 % to 87.6 % is optimal, which should be taken into account when selecting bulls to the breeding program.

A retrospective analysis of the dynamics of traits of milk productivity of Black-and-White cows with increased the part of Holstein breed blood has been carried out. Two groups have been formed from the number of culling animals of two adjacent generations: the 1st group (basic generation) with the part of Holstein breed blood of 3/4 (75 %) and the 2nd group with the part of Holstein breed blood of 7/8 (87,5 %) per 35 heads in each. As a result, it has been found that cows with the part of blood of 7/8 had the best indicators of milk productivity for I, II and III lactation. They significantly exceeded the indicators of cows with part of Holstein blood of 3/4 in terms of milk yield and yield of milk fat. The decrease in average daily milk yields for months of lactation in high-blooded cows was lower by 3 %, and the indicator of full-competed lactation was higher by 17,8 %. High-blooded animals have been culled out of the herd more intensively. By the end of the third lactation, the livability of livestock in the 1st group was 100 %, and in the second group – 23 %. The best parameters of productive longevity were distinguished by animals of the basic generation with the part of Holstein breed blood of 3/4. They signifi cantly surpassed of high-blooded animals in terms of longevity and period of productive longevity, respectively, by 1109 (P < 0,001) and 739 (P < 0,001) days, and in terms of lifetime milk yield – by 14392 kg (P < 0,001). The increase of the part of the blood of cows to 7/8 was carried out using purebred producers of foreign selection, the new generation of high-blooded animals had a relatively high genetic potential. However, 7/8-blooded cows of Holstein breed used it only by 53,4 %, which was by 24,3 % (P < 0,001) lower than the base generation. Thus, in the current environments of CJSC “Konstantinovo” high-blooded animals of Holstein breed do not suffi ciently realize the genetic potential, and the increase in productivity is associated with the loss of milk due to the decrease in the duration of economic use of animals. Based on this, we propose at the present stage to suspend the upgrading crossbreeding and return to the using Holsteinized sires domestic selection with the part of Holstein breed blood of 75 to 85 %.

Белок в молоке у дочерей разных производителей был на одном уровне — от 3,17 до 3,19%. По суммарному выходу молочного белка из-за колебаний в удое, размах признака варьировал от 279 до 344 кг. Племенная ценность (ПЦ) быков по удою составила 91,6—113,3%, 13 из них имели ПЦ ниже 100%, 8 голов — выше 100%. ПЦ по массовой доле жира равнялась 97,7—100,3%, по массовой доле белка — 99,6—100,3%. Суммарная ранговая оценка производителей по сочетаемости признаков их дочерей и женских предков показала, что бык АльтаПилснер 70344827 имеет явное преимущество по ПЦ перед другими производителями, его интегрированный коэффициент связи самый высокий и составляет — 0,78. Производитель Тач 69774799, напротив, занимает последнее место. Дана экономическая оценка использования производителей. Полученные материалы позволяют обеспечить положительную динамику селекционного процесса в молочном скотоводстве. The breeding value and genetic potential of 21 Holstein-stud bulls used in the herd of the stud farm of the Tver region were determined, where they were ranked according to a number of selectional features. The milk yield of the daughters of the evaluated bulls is 8700—10804 kg of milk with a mass fraction of fat from 3.81 to 3.95% and a milk fat yield of 346.4—414.9 kg. The protein in the milk of the daughters of different studs was at the same level-from 3.17 to 3.19%. According to the total yield of milk protein due to fluctuations in milk yield, the range of the trait varied from 279 to 344 kg. The breeding value (BV) of bulls according to the milk yield was 91.6—113.3%, 13 of them had a BV below 100%, 8 heads - above 100%. The BV for the mass fraction of fat was equal 97.7-100.3%, for the mass fraction of protein - 99.6-100.3%. The total ranking of the studs by the combination of the characteristics of their daughters and female ancestors demonstrated that the Altapilsner bull 70344827 has a clear advantage in BV over other studs, its integrated coupling coefficient is the highest and amounts 0.78. Tach 69774799 stud, on the contrary, takes the last place. There is given the economic evaluation of the studs usage. The obtained materials allow to ensure the positive dynamics of the selective process in dairy cattle breeding.

The Impact

Blood inflow of Holstein breed in Mari El cattle breeding, which began in 80s of the last century, had a positive impact on the dairy productivity of Black-and-White cattle. The research explores the impact of Holstein breed bloodline and lineage on the main indicators of cows’ dairy productivity in OAO Ovoshchevod. The productive age increasing, the live weight of cows in the main herd increased as well while the animals were relatively small. The cows of the eighth and ninth calves had the maximum live weight. On average, the cows with the third complete lactation (6791.5 kg) had the highest milk yield. The mass fraction of fat was on average higher than the basic fraction and was equal to 3.71%. The increase of milk fat concentration was observed in cows of the fifth and sixth lactations, with the offsprings of Black-and-White bull lines being the most fatty. There is a direct correlation between milk yield and the degree of blood flow in the Holstein breed. The fattiest milk cows were those with a blood content of 19%, while the cattle with a blood content of 75% had the lowest fat concentration in milk. According to the hospitalization data, most of the cows in the herd (including the first heifer cows) belong to the R. Sawring line. The female offsprings of Adam, Rikus and M. Chiftein bulls differed in the most productive longevity. The most abundant were cows belonging to M. Chiftein line. Female offsprings of Black-and-White bulls were inferior to the Holstein ones in average by 324 kg of milk. This feature was traced from first to fifth lactation. In the lactation section, the most fatty-milk cows of the Rikus and M. Chiftein lines were the fattest. As the share of blood in the Holstein breed increased, the milk yield per cow in the main herd increased as well. Thus, for cows with blood content of 18.75%, the average milk yield for all lactations was 6313 kg of milk. Further blood inflow of Holstein bulls led to this parameter increasing by 4% on average for cows with blood content of 25 and 37.5% for Holstein breed.

The purpose of the article is to evaluate the manifestation of economically useful signs of cow-daughters of Holstein breed different servicing bulls. Methods of the research. In the course of the study, commonly used zoo-technical methods (individual accounting of milk productivity, reproductive capacity), laboratory (determining the qualitative milk composition), retrospective analysis (indicators for the entire period of using animals), variation-statistical method (determining sign parameters) were used. The research results. As a result of using bulls for service of Holstein breed in creating a highly productive herd of dairy cattle it has been established that the level of developing productive, reproductive and adaptive properties of cow-daughters is influenced by the origin of the father-parent.  The correlation has been established between economically useful signs of cows-firstlings of the Holstein breed of German and Ukrainian selection from various bulls. Regardless of the experimental animals’ origin, there is a high-level positive correlation between the milk yield and the amount of milk fat and protein. The common peculiarity for the offspring of the Holstein breed is the presence of a positive correlation of the low, middle and high levels between the milk yield and the duration of the service period. The differences as to the direction and the degree of correlation dependence between productive and reproductive features of cows-firstlings have been determined, which characterize the diversity of bulls’ influence on their daughters. The elements of scientific novelty. The theoretical and practical propositions for raising the productivity of animals and creating highly productive herds of dairy cattle by using the gene pool of Holstein breed have been further developed. Practical significance. The obtained results should be taken into account in the process of improving the selection during the formation of a highly productive herd of the Holstein breed dairy cattle.

Productive Traits

Breeding work with dairy cattle in the Kurgan region is aimed at breeding animals that combine the adaptive properties and valuable traits of cattle of Black-and-White breed with a high proportion of genes of Holstein breed. Such animals are characterized by high productivity and suitability for intensive technology of their housing. The purpose of the research was to determine the indicators of milk productivity of first-calf heifers of different generations of Holstein breed, imported to the pedigree farms of the Kurgan region, as well as to determine the degree of realization of the genetic potential of animals. Scientific research has been carried out in the herd of CJSC “Glinka” (Kurgan), where highly productive cattle of Black-and-White and Holstein breeds are bred. The subject of research was the first-calf heifers of the imported Holstein breed of German selection of different generations, as well as the herdmates of Black-and-White breed. It has been found that the realization of the genetic potential for milk yield in Holstein cows of German breeding was higher and amounted to 76,4 %, in cows of Black-and-White breed 69,9 %. The highest milk yield for 305 days of lactation has been observed in the second generation of Holstein heifers 8905 kg, which exceeded the milk yield of herdmates of the second and third generations by 113 kg or 1,26 % and 174 kg or 1,95 %, respectively. The mass fraction of fat in German Holsteins of different generations ranged from 3,99 to 4,21 % (P < 0,001), while the mass fraction of protein in the milk of first-calf heifers varied slightly in the range from 3,18 to 3,20 %. In terms of live weight, the animals of the third generation slightly exceeded the herdmates of the 1st and 2nd generations by 19 kg or 3,25 % and 20 kg or 3,43 %, respectively. The largest profit has been received from the first-generation first-calf heifers of Holstein breed of German selection, where the level of profitability of milk production was 50,7 %, which was higher than that of the herdmates of the second and third generations by 3,9 and 7,9 %, respectively.

There are indicators data of body weight, body parts measurements, reproductive ability, milk production, morphological and functional properties of udder, the duration of use and economic reasons of disposal of Simmental cows in terms of Lviv oblast. It was established that the experimental cows by live weight during their growth in all ages have been prevailing minimum requirements of breed standard. They are marked by peculiar to combined breed type of body structure with well–defined not only milk but also meat forms, they had strong skeleton and were quite tall (withers height – 131.1 cm). However, the width of the breast in most cows, that is not enough for combined breed (on an average 41.4 cm). Simmentals age at the moment of the 1st insemination was 19.7, while during the 1st calving – 29.0 months, the duration of the service–period, depending on lactation, was within 96.8 – 112.0, of inter–calving period – within 381.6 – 396.9 day. They were characterized by an average fertility and high adaptablity. Simmentals milk yield, depending on lactation, was 3026,4–3810,2 kg, fat content in milk – 3.76 – 3.81% and quantity of milk fat 113.6 – 145.0 kg. Cows after the 4th calving had the highest milk productivity. During the all studied lactations cows milk yield and quantity of milk fat predominated breed standard. They had a well developed udder. 68.2% cows after the first calving had cupped udder, 25.9% – wash–tub and 6.9% – round udder. Their intensity of milk yield was 1.53 kg/min. Simmental cows duration of economic use in the conditions of Lviv oblast was 1.904.1 day or 5.3 lactations, lifetime yield – 18011, lifetime quantity of milk fat – 688 kg. Most reasons for dropped out of the herd was dysfunction of reproduction (35.7%) and low productivity (21.3%).

The origin of an animal determines its productive and breeding traits. It is well known that in dairy cattle breeding a great importance belongs to sires, especially those belonging to the leading lines of Holstein breed. The productive indicators of heifers and fi rst-calf cows the off spring of diff erent lines of Holstein breed and daughters of diff erent sires have been presented in the article. The researches have been carried out under the environments of specialized enterprises for rearing of replacement heifers and milk production. Diff erences have been found in the daughters of diff erent sires in terms of live weight and milk productivity. Accounting for the weight growth of the daughters of sires has shown that the live weight of heifers between the lines Wes Ideal 933122 and Refl ection Sovereign 198998 was not a signifi cant diff erence. Daughters of sire # 511H11283 of the line Refl ection Sovereign 198998 in all age periods had a live weight, absolute and average daily gain, the growth rate of replacement heifers was higher than the daughters of other sires. At one year of age, their live weight was higher than that of heifers-daughters of sires # 11H11596, # 11H11565 and # 511H11422, respectively, by 4,1 % (P<0,001), 3,1 % (P<0,01) and 5,0 % (P<0,001). The daughters of sire # 511H11283 of Refl ection Sovereign line also had a higher yield of calves – 104,8 %. However, the largest number of heifers (75,7 %) has been obtained from the daughters of sire # 11H11565 of Refl ection Sovereign line. In terms of milk yield, signifi cant diff erences have been found between the lines and daughters of diff erent sires. Higher milk yield was obtained from the fi rst-calf cows of line Wes Ideal 933122 (12361±321 kg) and the daughters of the sire Mogul 11H011757 (13587±328 kg). According to the mass fraction of fat and protein in milk, the duration of the period of open days and the number of inseminations, there were no signifi cant diff erences between the studied groups of animals. Thus, the infl uence of specifi c sires on individual productive indicators of daughters has been established.

Studies conducted in farm conditions, the company, OOO PZ «Nasha Rodina» in Sokolovsky village of Gulkevichsky district of Krasnodar region. The aim of the research was to study the use of the PassPro Soy feed product consisting of protected soy protein in the diets of new-bodied highly productive cows. 2 groups of cows of the red-mottled Holstein breed were formed, selected according to the principle of pairs-analogues: by age in calving, calving time, live weight, productivity for the past lactation, fat and protein content in milk. The ration of the first control group was the ration accepted on the farm for newbodied cows. The diet of the second experimental group was the same as in the first control group, only 1.5 kg of compound feed was replaced with 1.5 kg of PassPro Soy, which is a protected soy protein in the form of a 5 mm granule. During the milking period, the daily milk yield of cows in the control group was 30.80±1.07 kg. The daily milk yield of cows of the second group, where 1.5 kg of compound feed was replaced by 1.5 kg of PassPro Soy, significantly increased by 6.6 %. Due to the increase in the gross milk yield, there is a tendency to increase the amount of milk fat in the milk of cows of the second group by 6.9 %, as well as milk protein by 11.3 %. In the experimental group, when replacing 1.5 kg of feed taken on the farm with 1.5 kg of PassPro Soy, milk productivity increased by 2.03 kg. Additional profit from the sale of milk in the experimental group increased by 48.72 rubles. for 1 head per day. The economic efficiency in the second experimental group was 6.30 %.
