Ishkhanyan A. Improving reception productivity assessment pigs with different methods of breeding and the intensity of the formation of their body.

The thesis is devoted to improving methods of evaluation of performance of pigs born purebred or estates, and depending on the characteristics of individual development in the early postnatal period of ontogenesis. Proved that increased number born alive pigs of sows at thoroughbred breeding caused by higher energy growth of replacement chicks at 4 and 6 months of age, method of breeding and live weight of pigs at this age do significant impact on the variability of signs of reproduction, and high value of reproductive traits characteristic of the local sows who had energy growth - > 410 grams and bahatoplidnist for the first litter - >10 heads. However, further development has found provisions: depending live weight of sows and average daily rate, uniformity index growth gilts; predictability models Bridges T. and F. Richards live weight of pigs; type of compensatory growth gilts, especially landed origin group reduced live weight; the formation of a higher level of fattening qualities using cross breeding; the existence of comparable interior design variability between performance and body weight of animals that can be used in selection and breeding work for energy management and growth of replacement feeding calves.
