Abstract

The purpose. To develop technological method of ranging by alive mass repair young turkeys at their growing. Methods. Level of growing repair young birds was determined in view of alive mass and level of homogeneity in 20- and 30-week age. Presence of traumas at auk, preservation and expenses of feedstuff were determined on the basis of daily count. Yield of conditioned repair young birds was determined according to bonitation of turkeys in 30-week age. Efficiency of the offered method was determined by means of European Productivity Factor Index of production factors. Results. Differentiation by alive mass and feeding growing of repair young turkeys has allowed: to reduce expenses of feedstuffs for 1 bird — for 9,8%, for 1 kg of increase of alive mass — for 9,2 – 20,4%; to raise homogeneity of livestock as to alive mass and yield of conditioned pullets — for 10,2 – 19,6% (P<0,05); to promote increase of egg production of turkeys — for 6,5% (fatherly line) and 3,2% (maternal line), amount of hatchable eggs — for 2,2 and 0,7% accordingly, quantity of the bred turkey poultries — for 5 and 1,2 heads accordingly. Over-all economic benefit of the differentiated by alive mass and feedings growing of parental herd of turkeys has made 98,3 hrn/head. Conclusions. Key parameters of ranging turkeys by alive mass are specified and technological method of their differentiated selection, growing, content and feeding is developed.
