Effect of addition of multienzyme preparation VemoZyme®Plus on productive and slaughter parameters and meat composition of broiler chickens, fed wheat-corn-soybean meal diets

An experiment, lasting 42 days, was made to stady the еffect of addition of Bulgarian multienzyme complex VemoZyme®Plus on productive and slaughter performance and chemical meat composition of broiler chickens, fed wheat-corn-soybean meal based diets. In this trial 120 male one day old chickens of „Ross 308” hybrid, keep in battery cages, divided into 4 groups (distributed equally in three repetitions in each group) were used: 1. Positive control, fed with balanced diet ; 2. Positive control with addition of 0,05 % VemoZyme®Plus. 3. Negative control, fed with diet, contains 5 % less metabolizable energy(ME) and digestible essential amino acids (DEAA)–lisine, methionine+cistine, treonine. 4. Negative control with addition of 0.05% by VemoZyme®Plus. Tested enzyme preparation had no significant effect on the live weight, feed conversion, slaughter indices, protein and fat composition in the white meat of broiler chickens, fed with balanced diets. Addition of VemoZyme ® Plus to the diets of diminished nutritive value, increases (compared to the same, without addition of VemoZyme ® Plus) with 8,0 (P<0.05) and 5.7% (P<0.05) live weight, respectively through the grower and whole 42 days period, improved feed conversion with 11,0 (Р<0,05) and 4,7 % (Р>0,05) respectively through the grower and the whole fattening period, has a positive (Р<0,05) effect on grill weight (with 6,5 %), without significantly affecting percentage of protein and fat in the white meat, compared with the control group.
