Abstract
The main goal of this paper was to establish and reveal the role played by the BABY C4 (acidifier) feed additive in the chicken broilers rearing. The studied flock included 160 individuals, allocated in 4 groups: a control group -Lc and three experimental groups - E1, E2, E3. A specific percentage of feed additive inclusion has been established for each group, during a certain technological period, as it follows: - Lc = mixed fodder, standard formulated for each technological period; - E1 = +0.3% BABY C4 during starter period (1-7 days) and standard feed during the other periods; - E2 = +0.3% BABY C4during starter period (1-7 days), +0.2% during growing period (8-14 days) and standard feed during the finishing period; - E3 = +0.3% BABY C4 during starter and growing period and standard feed during the finishing period. The achieved results revealed that the chickens in the E1 group achieved better body weight (+35.84g) and a better average daily gain (+1.14g/chick), compared to the hybrid potential and obviously higher than other groups. The best results concerning feed consumption have been also achieved by the chickens in the E1 experimental group (81.65g/chick/day-average intake and 1.490kg feed/kg weight gain feed conversion ratio), compared to the chickens in the E3 experimental group (87.5g/chick/day-average intake and 1.679kg feed/kg gain).
