Experimental substantiation of the efficiency of use of canned wet corn grain when feeding cows in the industrial complexes
Abstract
The results of application of bacterial inoculum “Propicomb” in combination with sodium chloride for preservation of wet corn grain were presented and estimation of productive effect of such grain on dairy cows compared to dry corn grain was conducted. The whole canned corn grain in the volume of 700 tons was highly organoleptically evaluated. Biochemical parameters of its quality were as follows: dry matter – 71.8, pH – 5.88, total acidity – 0.68 %, acetic acid – 0.34 %, and lactic acid – 0.17 %. The average daily milk yield of the base fat (3.4 %) increased by 9.5% compared to control in the cows fed the diets that included 3 kg of grinded canned wet corn grain instead of 2.5 kg of dry corn (control).
