Влияние прилития крови на продуктивные качества свиней скороспелой мясной породы

The paper presents results of studies on the effect of cast-in the blood of animals Kemerovo factory type production pigs KM-1 isolates maturing beef breeds of pigs SM-1 (Siberian breeding). The study aimed to enrich the gene pool of the breed of CM-1 (Kemerovo selection) and the improvement of fattening and meat quality of pigs, using the method of induction crossing. The object of research pure-bred animals maturing beef breeds (SM-1) and animals with crossing the blood-type meat factory in Kemerovo pigs (SM-1) krovnosti 1/2SM-1 х1/2 KM-1 and 3/4SM-1x1/4 KM-1. Groups of animals for experimentation formed on the basis of pairs of analogs. All animals were kept under identical conditions of feeding and maintenance provided by technology companies. Hybrid animals exceeded the purebred counterparts in the control group on average daily gain of at 128-78 g (P
