Development and research of protein-mineral feed supplement effect on productive qualities and slaughter characteristics of rabbits

Abstract

One of the most topical issues today is the development of environmentally friendly agricultural products characterized by high quantitative and qualitative indices, which, in turn, is a necessary condition for ensuring human health. Trace elements necessary for life perform their functions in living organisms. Therefore, among the measures that should solve this problem, the most urgent is to provide the body of poultry and animals with the optimal amount and ratio of trace elements and proteins. This may be achieved by development of a new generation of feeds using secondary raw materials with protein and mineral value. The research goal is to develop and study the effect of compound feeds with a protein-mineral feed supplement based on connective proteins and precipitated calcium superphosphate on the physiological development of rabbits. This paper discusses the characteristics and properties of the components of the feed supplement being developed and the analysis of the amino acid composition of the protein component. The influence of the developed feed supplement on the absolute and relative growth rates of rabbits and their slaughter indices was studied. The work used generally accepted methods of research and conducting scientific and economic experiment. It was revealed that 12 g of the protein-mineral supplement per 88 g of grain mixture (protein/dicalcium phosphate - 2/1 ratio) was more effective as a feed supplement for young rabbits. The experiment revealed that the efficiency of the average live weight gain in the 3rd trial group increases by 10.61%; the average daily live weight gain - by 31.69%. Due to the supplement used, a high level of meat productivity was ensured; according to the calculated slaughter weight of rabbits, the 3rd trial group exceeded the control group by 12.42%. The data obtained indicate obvious effect of the developed supplement on the slaughter performance of rabbits; these changes are associated with a more productive development of muscle mass in the trial population of rabbits.
