The quality of pork when included in the diet of the drug Permaite

Abstract

It is well known that the growth rate of an animal depends on the level of feeding. However, the diets used in farms do not always meet the body’s needs for biologically active substances. In recent years numerous studies have been conducted to study the eff ect of natural and synthetic complex biologically active drugs on the productivity, metabolism of pigs and the quality of the products obtained. The imbalance or lack of certain nutrients in the diet reduces the productivity of animals, reduces the conversion of feed. The purpose of our research was to study the effect of the drug Permaite included in the diet of pigs on some indicators of the quality and safety of pork. Permaite is a standardized zeolite-containing trepel of the Chuvash Republic. Its chemical composition is (%): silicon oxide – 64,39, iron oxide – 3,25. aluminum oxide – 8,42, titanium oxide – 0,45, calcium oxide – 7,74, calcium carbonate – 14,7, magnesium oxide – 1,71, potassium oxide – 1,81, sodium oxide – 0,03, phosphorus pentoxide – 0,20 and other impurities – 11,9. Experimental studies have been conducted on 2 groups of pigs on rearing and subsequent fattening. Pigs of the experimental group have been received the main diet with the inclusion of the drug Permaite at a dose of 3 % to the dry matter of the main diet in the form of a fraction of 0,1–0,3 mm. The drug has been prescribed once a day in a mixture with compound feed for 60 days. The control group of pigs during this period was on farm diet without the inclusion of the drug. Upon reaching the live weight of 100–110 kg the pigs have been sent for slaughter. The results of the research allow us to conclude that the inclusion of the drug Permaite in the dose of 3 % to the dry matter of the main diet provides the increase in the nutritional, biological, energy value, technological properties and safety of pork.
