Use of deoxidized hydrochloric acid and sulfuric acid casein whey for pigs feeding

Abstract

As a result of research the following key indicators were determined: the content of the metabolizable energy - 0,74 MJ, dry matter - 64,5 g, protein - 7,4 g, fat - 0,2 g, lactose - 49,2 g, ash - 7,8 g, calcium - 1,1 g, phosphorus - 0,8 g, pH of deoxidized casein acid whey is 5,0-5,6. The maximum storage period of deoxidized whey was determined. At a storage temperature of +20 °C the whey pH 5,6-5,0 is retained no more than 3 days, at temperature of +5 °C up to 7 days. In experiments on the deoxidation of the whey it was determined that most efficient deoxidizer is baking soda, and the cheapest one - OPSUK. In the scientific and economic experiments with sulfuric acid casein deoxidized whey which took 10% of the nutrient value of feed mixture for piglets at fattening it was found that the average daily live weight gain in the experimental animals increased by 9,6 %, with deoxidized hydrochloric acid casein whey increase energy of growth was increased by 3,3 %. As a result additional notional profit per one animal amounted to 41,500 rubles when feeding with deoxidized sulfuric acid whey and 20,550 rubles when feeding with deoxidized hydrochloric acid whey.
