EFFECTS OF ENZYMES, PROBIOTICS AND LIVER TONIC ON LIVE WEIGHT AND HEMATOBIOCHEMICAL PARAMETERS IN BROILER

Abstract

The experiment was conducted on “Cobb 500” broiler chicks to investigate the effects of probiotics, enzymes and liver tonic supplementation on live weight and hematobiochemical parameters (TEC, Hb concentration, PCV, ESR, TLC, AST and ALT). A total of 250 day-old broiler chicks were allowed to take rest for 13 days for the adaptation and supplied with normal diet and water. After day 13 they were randomly divided into four equal groups (N=50) and marked them as group T0, T1, T2 and T3. Broiler chicks of group T0 were kept as control and fed with only the commercial broiler ration and fresh drinking water for 21 days but the group T1, T2 and T3 were treated with probiotics (Protexin ) @ 1gm/L, probiotics (Protexin ® ) @ 1gm/L, enzymes (Alquerzim ® ) @ 1 gm/L plus liver tonic (Livavit ® ) @ 1gm/L plus enzymes (Alquerzim ® ® ) @ 1ml/L drinking water with normal diet for 21 days respectively. Live weight as gm of broiler chicks were measured on the day 14 of age (1 day of experiment) and sequentially at 7 days interval up to the end of the experiment (day 35 of age i.e21 st day of experiment). For the hematobiochemical examinations, blood samples were collected from the randomly selected 10 (i.e. n = 10) birds from each and every group at the end of experiment on day 35 of age (21 st day of experiment). It was observed that live weight were increased significantly (p<0.01) in the treatment groups(T1, T2 and T3) as compared to control group T0. TEC, Hb concentration and PCV were increased significantly (p<0.01) but the ESR and TLC significantly (p<0.01) decreased in all the treatment groups as compared to control group st T0. Serum biochemical parameters like AST and ALT values were also decreased significantly (p<0.05) in the treatment groupsas compared to control group T0. Therefore, it may be concluded that additional probiotics, enzymes and liver tonic supplementation had better performance in terms of live weight gain and hematobiochemical parameters without any detrimental effects in broilers.
