INDICATORS OF PROTEIN METABOLISM AND THEIR RELATIONSHIP WITH FATTENING AND MEAT QUALITIES IN YOUNG PIGS OF DIFFERENT GENOTYPES
Abstract
The article presents the results of studies of some biochemical parameters of blood serum, as well as fattening and meat qualities of young pigs of large white breed of different genotypes by the gene of the melanocortin receptor MC4R. The research was conducted in «Druzhba-Kaznacheyivka» LLC of Dnipropetrovsk region, «Jazz» meat-packing plant, research center of biosafety and ecological control of agro-industrial resources of Dniprov’sk State Agrarian Economic University, genetics laboratory of the Institute of Pig Breeding and Agroindustrial Production of NAAS and of Animal Husbandry of the State Institution Institute of Grain Crops of NAAS. Evaluation of young pigs of large white breed for fattening and meat qualities was carried out taking into account the following indica-tors: the average daily increase in live weight during the period of control fattening, g; age of live weight 100 kg, days; fat thickness at the level of 6-7 thoracic vertebrae, mm, length of chilled carcass, cm; length of the bacon half of the cooled half-carcass,cm (Berezovsky, Khat’ko, 2005). DNA-typing of animals was performed in the genetics laboratory of the Institute of Pig Breeding and APV NAAS (Kim, Lee, Shin et al., 2006). The content of total protein (g/l) and the level of urea (mmol/l) in the serum of 5-month-old animals were studied according to conventional methods (Vlizlo et al., 2012). Biometric parameters were calculated according to the methods of Lakin (1990). It was found that the biochemical parameters of blood serum of young pigs of experimental groups correspond to the physiological norm of clini-cally healthy animals, and young pigs of genotype MC4RAG significantly outperform peers of genotype MS4RAA at the age of 100 kg, thickness of fathead minnow on average by 4.47 %. The number of significant correlations between biochemical parameters of blood serum, fattening and meat qualities of young pigs of large white breed of genotype MC4RAA is 40.00 %, MC4RAG - 50.00 %. This indicates the possibility of using interior indicators for early prediction of fattening and meat qualities in young pigs of large white breed. The maximum increase in additional products was obtained from young pigs of large white breed of the MC4RAG genotype by the melanocortin receptor gene. It is +2.02 %.
