METHOD FOR DETERMINING THE ANNUAL Meat efficiency of beef cows Charolais

摘要

A method of determining and predicting the annual productivity meat cattle meat breed sharole for the entire production period of use is presented as the total live weight of two detachable data steers and heifers first three audio calving, their birth weight and weight after feeding culled cows, reduced; calculated for annual and represented by the formula; R≈0,19 · [F + 1,7 (F + R · T) 0.85 (P + P · T)] where F is the average beef cow meat efficiency sharole ; P- weight culled cows after feeding kg; P- calf weight at birth kg; P- daily gain in suckling calves kg; P- daily gain in suckling heifers kg; T suckling calves during the rearing period, days .; 0.19; 1.7 and 0.85 - corrective breeding and technological factors.
