Целью соответствующих исследований являлось выведение скота характеризующегося высокой молочностью и хорошей мясной продуктивностью. Для переменного скрещивания использовали местный черно-пестрый скот, а также гольштино-фризский и шведско-фризский (СЛБ) скот. На первом этапе определяли откормочные и убойные качества потомства с генотипом: 1/4 черно-пестрой, 1/4 гольштино-фризской и 1/2 шведско-фризской...
Исследовали химический состав и питательные качества сушеной твердой фракции жидкого навоза свиней, а также ее влияние как компонента полнорационных смесей на результаты откорма быков. Один килограмм сушеной твердой фракции отвечал 0,638 овсяной единицы и содержал 54 г переваримого белка. Животные были разделены на три группы (по 8 голов в группе), а их откорм продолжался до достижения веса тела с...
Two experiments on lowland black-and-while dairy cows of Holstein-Friesian variety and on F₁ generation from crissing the Polish black-and-white cows with Holstein-Friesian bulls were carried out. The protein level in dry matter of the ration amounted as follows: in the experiment I in the ration A - to 12.7, ration В to 14.2, ration C - 15.4% and in the experiment II - to 13.8-14.0, 15.8-16.0 and...
Thirty six young bulls with the average body weight of 230 kg were fattened for 247 days. The bulls were divided into 3 groups by 12 heads in each group. Bulls of the control group I were fed ration with the following composition (in % of d.m.: maize silage - 68.1, bruised oat grain - 28.8, urea preparation ŁMZ - 2.7, mineral mixture MMB - 1.0.
