RESEARCHES ON THE USE OF FEED ADDITIVE BABY C4 IN BROILER CHICKEN DIETS

The purpose of this paper was to assess parameters of broiler chicken productivity in terms of using a feed additive based on butyric acid. There were used 3 groups of chicken every group of 75 subjects, it was made a control group (C) and two experimental groups (E1, E2) which was feed with a supplemented diet with feed additive Baby C4 in different proportions: 2 % in the first 21 days at E1 group and 3 % in the first 7 days at E2 group. It was found an increase in body weight of experimental group of chickens around 6% (E2) to 8% (E1) and a reduction in specific consumption by 5% - 8% corresponding of lots E1 and E2 respectively, compared with body weight and specific consumption in the control group of chicken. For an analysis with an exactly results it was calculated European efficiency factor indicating E2 group with an index of 410 in first place followed by the E1 group with 400 and control subjects with 351.
