Abstract
This research was conducted out at Jerash University farm in Jordan, 2020. The aim was to evaluate the effect of some feed additives, two levels of Omega-3 (5 kg/ton) [T1], (10 kg/ton) [2] and (Probiotics with exogenous enzymes mixture, 1 kg/ton) [T3], and commercial feed [T4] on growth performance and carcass parameters of Hubbard chicks during 16-35 days of age. A hundred forty and four birds at sixteen days old Hubbard chicks were distributed randomly into four treatments. Each treatment included 3 replicates, 12 chicks in each replicate. Data were analyzed by SAS (2012). Live body weight (Wt) at 28-day-old, T1 had a higher than the T4. Weight gain (WG) was significantly differed among treatments, as it exceeded the T1 during the fourth week and the T4 during the fifth week. Feed consumption (FC) significantly differed among treatments; T4 had the least FC during the third and fourth weeks while T3 had the least FC values during the fourth and fifth weeks. The feed conversion ratio (FCR) was significant among the treatments during the fifth week, where the T1 was the highest. WG, FCR, and mortality were significant, while FC was significant between treatments, as T3 was the least during the full rearing period (35-days). The carcass characteristics were not significant except for dressing percentage and spleen weight were lower at T1 and T3, respectively. The research findings indicated that Probiotics with digestive enzymes could decrease FC without affecting final body weight at Hubbard broiler chickens under the conditions of production in Jordan.
