The aim of our research is the evaluation and selection of Dutch cows’ desirable type of body composition, with high milk yield, good reproductive capacity and high economic efficiency of their usage. Experimental animals have been the 50 daughters of Dutch bull-inseminator Cashmere Et 13167177 of line Reflection Sovering 198998. The place of research is “Agro-Soiuz”, Dnipropetrovsk region. It has been discovered that cows of high- and middle-capacity body composition gave greater average increase of primary production per one animal for the second lactation compared to low-capacity body composition peers respectively: 6697,5 and 5054,9 UAH. Among the cows of high-capacity body composition because of the elongated between-calving period, milk loss per animal per second lactation were greater compared to low-capacity peers on 227,0 kg. The best ones, according to the combination of milk yield level and the duration of between-calving period were Dutch cows with middle-capacity body composition among which the milk loss by the reason of elongated between-calving period have not been found.
The average level of production profitability of 1 centner of milk at the enterprise. The mean operating time of of Holstein cows is in the household is 2,3 lactation. It have been spent 22 thousand UAH on rising one cow from birth to first calving. Calculatingly, per lactation, this value is 9565 UAH. According to the data, the cost of production of 1 kg of milk for 2014 is 3,10 UAH. The cost of total volume of milk produced during 305 days of second lactation was higher at more productive animals, in comparison with high- and mid-capacity body composition types. As the result, the common costs for milk production was more from them respectively: 4526 and 3407 UAH, compared to their peers low-capacity body composition, and the price cost of 1 kg of milk, respectively: 3,90; and 3,93 4,01 UAH. This index in 2014 was 29.6 %. According to our economic efficiency calculations, it was found that the best were Dutch cows of high-capacity body composition. Calculations for one Dutch cow of this type per 305 days of the second lactation, the net profit is 15922 UAH when the level of profitability is 34.2 %, respectively against: 12653 UAH and 30.1% of peers with low-capacity body composition. From each cow of mid-capacity body composition, it was received 15313 UAH net profit at the level of profitability 33.7 %, respectively against: 12653 UAH and 30.1% of peers with low-capacity body composition. These indexes testify about the feasibility of conducting the selection of Dutch cows according to the type of body composition by the method developed by us, which will increase the profit of the dairy cattle breeding.

Key words: body composition, economical efficiency, high-capacity cows.

Представлены результаты оценки экономической эффективности использования коров голштинской породы в зависимости от типа конституции, установленного по разработанному методу, который основывается на определении объемно-весового коэффициента (ОВК), с учетом площади поперечного сечения груди за лопатками и на уровне последнего ребра, длины грудного отдела и живой массы. Установлено, что уровень рентабельности производства молока коров крупно- и среднеобьёмного типа выше, чем представительниц малообъёмного типа конституции соответственно на: 4,1 и 3,6 %.

Представлено результати оцінки економічної ефективності використання корів голштинської породи залежно від типу конституції, визначеного за розробленим методом, який ґрунтується на розрахунку об’ємно-вагового коефіцієнту (ОВК), з урахуванням площі поперечного перетину грудей за лопатками і на рівні останнього ребра, довжини грудного відділу та живої маси. Визначено, що рівень рентабельності виробництва молока корів велико- і середньооб’ємного типу вища, ніж представниць малооб’ємного типу конституції відповідно на 4,1 та 3,6%.
