The results of wholesale on the use of waste of vegetable crops and sunflower when fattening gobies of the black-and-white breed are given. Six groups of uncastrated bulls were formed: control, I experienced, II experienced, III experienced, IV experienced and V experienced (on the principle of analogous groups, taking into account age and body weight and origin). All gobies (control and experimental groups) were given 17.2 kg of silage from cereal perennial grasses and 3.65 kg of mixed feed and 9.5 kg of brewer’s grain, 80g of fodder chalk each. The gobies of the experimental groups were given various wastes of vegetable crops and sunflower (at 30 g / head / day): I experienced — did not feed them, II experienced — pepper stalks, III experimental — sunflower stalks, IV experimental — cucumber stalks, V experimental — stalks tomatoes (in the form of flour). The live weight of bulls when removed from fattening for the control group is 297.0 ± 0.19 kg, the experienced ones - from 304.6 ± 0.12 kg (hay with KKS and without feed additives) to 317.7 ± 0.24 kg (114.7%, tomato stalks). Average daily gains in live weight are from 801 ± 14.6 g (hay with CCR) to 874 ± 16.7 (tomato stalks, P <0.001) versus 762 ± 16.4 g in the gobies of the control group.
