“…Пошук резервів підвищення молочної продуктивності та продуктивного довголіття тварин є актуаль-ним питанням для вітчизняного та зарубіжного молочного тваринництва в зв'язку з скороченням термінів їх господарського використання в останні десятиліття (Gіll, 2008;Compton et al, 2016;De Vries, 2017;Milostiviy et al, 2017). Особливої гостроти ця проблема набуває серед стад високопродуктивних корів, фізіологічні процеси яких перебувають на межі біологічних можливостей, часто межують з патологічним станом організму (Chebel et al, 2016).…”

Sklyarenko, Y.I. (2018). Features of milk productivity of cows of Ukrainian brown dairy breed and the influence of genotypical and paratypical factors on its formation. Scientific MessengerThe indicators of milk productivity of cows of Ukrainian brown dairy breed were studied. The research was carried out on the basis of breeding farms of animal breeding of this breed by assessing the data of primary zootechnical accounting. It is established that the level of milk productivity of cows meets the breed standard and is within 4.5 thousand kg of milk. A significant correlation between the indicators of milk productivity and reproductive capacity was found. Milk productivity is negatively correlated with the main indicators of reproductive ability. The influence of genetic and paratypic factors on the formation of milk productivity was studied. It is established that a conditional bloodedness, linear membership and origin in the father significantly affects the level of milk productivity of cows. The impact of genetic factors increases from conditional crow nest of Swiss breed to descent on the father. Animals with the highest proportion of Swiss breed were significantly dominated by other animals by the milk yield per the first lactation. The highest milk yield in the first lactation were obtained from the animal of Vigate 083352 line and the smallest of Payvan 136140 line. By the greater amount of milk fat and protein, the animals of the Vigate 083352 line also prevailed. Animals from different bulls for the first lactation had milk yield in the range of 2780-4464 kg of milk, the amount of milk fat and protein, respectively, 103-176 kg and 89-134 kg. A big impact on the economy of milk production having a term of economic use of animals. Therefore, in our view longevity as a symptom of dairy cows is an important selection basis. The significant influence of genotypic factors on the indicators of the duration of use and lifetime productivity of cows was established. The greatest impact of the paratypical factors had the farm, which contains animals. The conditions of keeping and feeding in the farm had a significant impact on the duration of use and lifetime productivity of cows. The presence of significant influence of genotypic and paratypical factors on the milk productivity of animals makes it possible to improve its breeding and technological activities.

Поиск резервов повышения продуктивного долголетия животных является актуальным вопросом для отечественного и зарубежного молочного животноводства в связи с сокращением сроков их хозяйственного использования в последние десятилетия [4,9,12,13,17,19,26,25]. Особую остроту эта проблема приобретает среди стад высокопродуктивных коров, физиологические отправления которых находятся на пределе биологических возможностей, зачастую граничащих с патологическим состоянием организма [10,16,23,27].…”

Score productive longevity of dairy cattle is an important scientific and practical importance. It is known that among genetic factors, significant effects of linear affiliation of their parents. It is demonstrated that effective breeding subject to strict compliance with the screening system, selection and evaluation of animal breeding values reported by domestic and foreign authors. The purpose of the work was to study the influence of linear membership on productive longevity and lifetime milk productivity of Holstein cattle of European breeding. Studies carried out on cows Holstein breed using data management system dairy cattle breeding "Orsek". Found that targeted breeding work and selection in a herd of imported European cattle breeding Holstein using information systems selection bulls MAR company CRI meets the latest requirements of the ICAR and Subcommittee on the unified international assessment of manufacturers (Interbull) contributed to a change in the number of separate lines among the cows first generation. This has led to an increase in the percentage of manufacturers lines daughters Valiant 1650414.73, Starbuc 352790.79, as well as Cheef 1427381.62. on the basis of the desired economic-useful signs. It is established that the value of productive longevity of cows depending on linear conditioning averaged 3.1 ... 3.9 lactations. By this measure, the daughter of Starbuck's lines were superior animals Holstein breed other lines by the number of lactations: Chevalier – 0.1 or 2.6% (td = 0.25; P ≤ 0.95); Bell – 0.5 or 14.7% (td = 0.95; P ≤ 0.95); Valiant – at 0.8 or 25.8% (td = 1.52; P ≤ 0.95); Eleveyshn – 0.8 or 25.8% (td = 1.91; P ≤ 0.95); Cheef – 0.5 or 14.7% (td = 1.27; P ≤ 0.95). It has been proven that milk productivity and milk quality of the imported Holstein cows and their offspring of domestic generation attributable to linear. The highest lifetime yield of Holstein breed cows had Starbuck lines, which outnumbered their import contemporaries other lines: Chevalier – 2818.7 kg or 8.2% (td = 0.46; P ≤ 0.95); Bell – 3404.5 kg or 10.1% (td = 0.61; P ≤ 0.95); Valiant – 5553.8 kg or 17.5% (td = 1.26; P ≤ 0.95); Eleveyshn – 7368.9 kg or 24.6% (td = 1.78; P ≤ 0.95); Cheef – 5500.5 kg or 17.3% (td = 1.38; P ≤ 0.95). The father's genotype had a significant impact on the quality of the milk. It should be noted that cows Starbuck's line differed relatively high fat content in the milk. By this measure the superiority of animals this line over imported cows other lines: Chevalier – 0.5% (td = 2.38; P ≥ 0.95); Bell – 0.2% (td = 1.38; P ≤ 0.95); Valiant – 0.6% (td = 2.78; P ≥ 0.95); Eleveyshn – 0.4% (td = 3.23; P ≥ 0.99); Cheef - 0.2% (td = 1.44; P ≤ 0.95). However, large protein content in milk cows belonging to different lines of Bella, who on this indicator had superiority over animals other lines: Chevalier – 0.2% (td = 1.03; P ≤ 0.95); Starbuck – 0.1% (td = 0.59; P ≤ 0.95); Valiant – 0.5% (td = 2.31; P ≥ 0.95); Eleveyshn – 0.2% (td = 1.85; P ≤ 0.95); Cheef – 0.1% (td = 1.15; P ≤ 0.95). It should be noted that only the cows first generation Valiant lines and Eleveyshn marked positive relationship between life and the content of cows in milk fat and protein (r = +0.17 ... +0.40), which may indicate the possibility of holding breeding work to improve these symptoms. So in the breeding work it is advisable to use manufacturers of prominent lines that combine high breeding value on productivity of daughters with improving effect on the duration of their use. The results of the research show that the effective use of well-known manufacturers and imported Holstein breed brood in breeding work with dairy cattle of Ukraine. However, shortening the productive use of animals in conditions of industrial technology should serve as a stimulus to study and find ways to solve this problem.
