Mateush V. Technologi perfection of repaired heifers growing using the regional fodder mixtures

The experiments were done on remedial yoang Ukrainian Black-Spotted Dairy breed from heifers birth till first-calving cows (the first three months of lactation). Animals were divided due to the methods of analogies into three groups, twelve heads in each. Firs group was control. Heifers of experimental groups (the second and the third) were fed with special milk mixture instead of skim-milk. Heifeis of more than 6 months, dry cows and cows from control group were fed during stable period with corn silage, and in experimental groups - with combined (corn of waxed ripeness with oil horse radish - 3:1). The coefficient of the digestibility of nutrients and nitrogen balance in animals from the experimental group was higher. The indices of cicatrix, blood and urine were found aut more optimal. The investigations had provided for directed growing of remedial heifers with the help of their rise in feeding from the early age, specially prepared weight by volume pfodder for the their better growth and the development of digestive tract. The preparing of feed were performed thanks to modern machine using: extruder, "John Deere" combine, and "Mono-Feeder" fodder-distributor-crusher. Cows from welldeveloped heifers eal pasture grass and weight by volume fodder during stable period. Keywords: remedial heifers, directed growing, combined silage, digestibility of nutrients, milk mixture.
