Pankiv L. Energy estimate of different teсhnology elements, breeds and sheep-raising production systems in Ukrainian Woodsteppe

Various sheep genotype young stock breeds & performance trends, the dams of Precos breed by different lamb times & various maintenance systems were studied. Zootechnical, power economy & economical indices of sheep-breeding production manufacture were investigated. Statistical analysis, laboratory, chronometric & research expedition investigations were carried out. Calculation technique was elaborated. Overall energy content in mutton of young & adult sheep was determined. Aggregate energy content was calculated according to the sex & genotype of sheep of various age. Energy loss rate & its evaluation by wool & mutton manufacture were defined too. Such estimation was assessed by various sheep keeping techniques application & utilization of different maintenance systems. The technological methods of wool & mutton manufacture were elaborated by energy loss wane & labor expenditure sag. Aggregate energy loss methods & manufacture efficiency technique elaborations were presented. The dwindle of primary cost of production unit per 25-30% was achieved. Sheep-breeding.
