PRODUCTIVITY OF PIGS AND QUALITY MEAT WHILE FEEDING PREMIX BIOLEKKS AND BENTONITE
O. V. Ivanova, E. A. Ivanov
Abstract: Researches on feeding with Biolekks premix and bentonite clay to pigs for fattening were conducted. It was established that the tested additives have beneficial effect on animals. However the greatest effect was obtained with combined feeding. So the live weight of pigs increased by 5.2% (at P≤0.999), surviving – by 4%, the level of profitability of pork production – by 18.6%,
also revealed was the decrease of concentration of mercury in meat – by 37.5%.
It is obvious that Biolekks premix and bentonite has allowed balancing the diet with minerals, improving digestion of nutritious and biologically active components of feed, normalizing the metabolism, excreting heavy metals such as mercury, which all ensured the growth rate, the surviving of pigs and economic efficiency.
