A new approach to sustainable pork production through the use of innovations in feeding

Abstract

Abstract The aim of the research was to assess the quality indicators of pork from two or three pedigree pig hybrids imported from Denmark during industrial feeding. 3 groups of piglets were formed, 20 heads each at the age of 2 months. In the course of the research, zootechnical, biochemical, physicochemical and mathematical methods of analysis were used. The resulting digital material was processed by the method of variational statistics, taking into account the Styudent’s confidence criterion, using the software package Mikrosoft Excel. It was found that the two and three breed hybrids were characterized by high gains in growth, and reached 100 kg of live weight earlier than pure breed analogs of the Landrace breed. Their carcasses also contained more muscle tissue by 1.0 and 1.7%, the ratio of muscle tissue to fat tissue was higher by 0.16 and 0.29%, respectively. Pork obtained from two and three breed hybrids contained more tryptophan and oxyproline in comparison with purebred animals which may indicate its greater biological value. Thus, meat raw materials obtained from two- and three-breed hybrids during industrial cultivation are leaner in comparison with purebred animals, which is preferable for food production.
