The effect of probiotic additive Biogumitel 2G on the efficiency of nutrient use in fodder rations
The article presents the results of the probiotic feed additive Biogumitel 2G usage when feeding bulls of Simmental breed under the intensive growing for meat. It has been found that the bulls of experimental groups were superior to their peers in the control group by the consumption of feed units by 1.4-2.3%, metabolizable energy (42.1-154,0 MJ), digestible protein (2.7-5.7%). It has led to greater consumption of all types of nutrients by the bulls of experimental groups. The bulls of the third experimental group receiving the probiotic feed additive 0.10 g per 1 kg of live weight occupied the leading position according to the value of studied indicator. Thus, the advantage of the third experimental group of bulls over the peers of the second experimental group according to the digestibility rate of dry matter was 0.53%, organic matter (1.45%), crude protein (1.59%), crude fat (1.36%), crude fiber (2.21%), NFE (1.17%). Young animals of the control group conceded to the experimental groups by the consumption of dry matter (113,2-186,7 g); organic matter (101,1-167,5 g); crude protein (11.9-19.6 g); crude fat (3.2-5.0 g); crude fiber (23.1-37.8 g); NFE (62.9-105,1 g). The use of probiotic feed additive Biogumitel 2G contributed to a more efficient use of all kinds of nutrient in a fodder ration by the bulls of experimental groups
