Abstract

The article presents the results of the study of productive and metabolic effect of the use of a protein-vitamin-mineral supplement (PVMS), an improved formulation, as part of the feeding rations of young repair ewes of the Ukrainian mountain-Carpathian breed in the conditions of the natural-climatic zone of the Carpathian foothills, by introducing into their composition local highly nutritious feed components. The research was carried out during a two month period (February – March) in the conditions of the Radvan-Nova farm (Myloshevychi village, Pustomytivskyi district, Lviv region) on young ewes of the above breed in the winter-spring stall period. For this purpose, three groups of 12-month-old young ewes of 10 heads in each group (control and two experimental) were formed by the method of analogues, which were kept separately with the provision of proper care and level of feeding. The feeding ration consisted of meadow grass-herbaceous hay (unlimited), oat-pea straw (unlimited) and compound feed. The calves of the control group received 0.4 kg of standard compound feed according to the recipe of the ITSR named after M. F. Ivanov "Askania-Nova", the young ewes of the first experimental group – the same amount of experimental compound feed, the young ewes of the second experimental group – 0.3 kg of a mixture of whole grains of oats, barley, corn and 0.1 kg of experimental PVMS. The conducted studies established that, in the conditions of the indicated climatic zone, feeding of 12-14-month-old young ewes with the rations of compound feed and PVMS including local feed ingredients in their composition, compared to standard analogues, provides an increase in indicators of weight and linear growth of animals, a decrease in monetary expenditure on increases in live weight, improves biochemical indicators of metabolism in the blood. It is also shown that the use of compound feed and PVMS of an improved recipe compared to standard feed, when growing repair young ewes of the Ukrainian mountain-Carpathian breed aged 12–14 months in the winter-stall period makes it possible to reduce monetary costs for obtaining 1 t of growth gain by 10–13%
