METHOD OF INCREASE OF EFFICIENCY OF BULL-CALVES OF DAIRY PERIOD BREEDING Russian patent published in 2008 - IPC A23K1/175 

FIELD: agriculture.

SUBSTANCE: method includes introduction of mineral top dressing from aluminum silicate and organic acid in a diet. As organic acid, use amber acid in a dose of live weight of 20-30 mg/kg. In addition apply ascorbic acid in a dose of live weight of 5-6 mg/kg. As aluminum silicate, use celadon green of the Karijsky deposit of the Chelyabinsk area with the following chemical compound: silicon oxide - 70.6 %, aluminium oxide - 4.6%, ferric oxide - 12.8%, magnesium oxide - 2.2%, manganese oxide - 0.02%, potassium oxide - 3.9 %, phosphorus oxide - 0.04% and the content of minor elements (mg/kg): copper - 5.9, zinc - 37, cobalt - 17.3, manganese - 21, lead - 10,2, nickel - 15.5, cadmium - 0.98, mercury - 0.04, arsenic - 3.8, which are applied in the form of glauconitic concentrate (fraction of 0.01-0.1 mm) in a dose of live weight of 145-155 mg/kg which in the beginning is entered into a diet in 100 ml of a 0.5% water solution of an agar with milk, in the aftermilk period - with mixed fodder, 1 time a day during the growing period.

EFFECT: increase of meat efficiency of bull-calves at intensive technology of breeding in the conditions of industrial complexes.
