Abstract

It was observed the data on milk production and cows’ breeding value of different cows’ bloodlines of the Precarpathian inbreed type of Ukrainian red–spotted milk breed in the PSP "Mamaivske» Chernivtsi region. It was found, that in recent decades in the farm were established 43 uterine bloodlines. The ancestor’s milk yield of the better lactation was ranged from 3117 to 9287 kg. The best in terms of milk production were ancestors Shchuka 7331 (9287–3,70–343,6), Vyshnia 2047 (8619–3,60–310,3), Chaika 4476 (8152–3,70–301,6) Krapka 9244 (7200–3,82–275,0) Lada 2717 (7735–3,70–286,2) Holenka 2462 (6718–3,80–255,3) Havrochka 2768 (6227–3,80– 236.6), Slota 2079 (6222–3,83–238,3) and Orbita 8946 (6005–3,80–228,5) and the highest breeding value for milk yield were observed ancestors Shchuka 7331 (1033.8 kg) , Vyshnia 2047 (866.8 kg), Chaika 4476 (750.0 kg), Krapka 9244 (512.0 kg), Holenka in 2462 (391.5 kg). It was established, that the daughters of high productive ancestor not always were mentioned of high milk yields and, conversely, low productive – low milk yields. From ancestors Shchuky 7331, which had milk yield 9287 kg was obtained daughter, milk yield which for the best lactation was only 3300 kg, and ancestors Mylia 3850, Shchekolda 2,458 and Zebra 5987, hopes for the best lactation which were 4358, 3467 and 3987 kg were given daughters yields of 7005, 6406 and 6265 kg respectively. The most numerous were bloodlines Oreli 9660 (26 h.) Alma 6215 (24 h.) Chaiky 4476 (24 h.), Pavy 2720 (23 h.) Azy 2038 (21 h.), Sopilky 4216 (21 h. ) Orbity 8946 (20 h.), Varny 2645 (19 h.) Holenkoi 2462 (19 h.) Havrochky 2668 (19 h.), Mixtures 7007 (18 h.), Osyny 5101 (18 h.) Romashky 3411 (18 h.). The best milk yields were bloodlines Azy 2038, Krymka 2767, Dykoi 3001, 2458 Shchekoldy, Yachts 285, Chaika 4476, Kukhni 3292, Krapky 9244, Dobroi 3442, the average milk yield for the best lactation which was more than 5,500 kg. The highest breeding value for this index were characterized bloodline Chaiky 4476 (104.3 kg), Azy in 2038 (99.0 kg) Krapky 9244 (93.0 kg), Kamy 4 (92.9 kg) and Krymky 2767 (85.9 kg). Among the estimated bloodlines 25.6% were classified to progressive category, 53.5% – to stable and 20.9% – to regressing
