Abstract:
Probiotic (Addon Poultry Max) effects on growth performance (body weight gain, feed consumption, feed conversion ratio) and carcass characteristics (ready to cook yield, weights of liver, heart, gizzard, abdominal fat, intestine, breast yield, spleen, thymus, and bursa) were studied. Two hundred and forty, day old chicks were allocated randomly into four treatments with three replicates in each treatment (20 birds in each replicate) and were fed standard feed. The trial was conducted for 42 days which comprised of four dietary treatments wherein, T1 served as basal diet. Basal diet+ 250g/ton (AGP), basal diet + probiotic (Addon Poultry Max @250g/ton) and basal diet + Probiotic (Addon Poultry Max 250g/ton) and Enrofloxacin (10ml/100kg BW) levels were designated as T2, T3 and T4 respectively. There was a significant increase in the body weight gain, feed consumption and feed conversion ration in T3 group followed by T4 group when compared to the control (T1) group. All dietary supplements did not have significant (P>0.05) effect on various carcasses parameters except breast yield. The breast yield was significantly (P<0.05) higher in probiotic, at 42 days, while the rest of the treatment groups did not differ from control. Mortality was more in control group and least in combined antibiotic and probiotic supplemented group followed by probiotic added group. Hence, it can be concluded that, supplementation of probiotics (Addon Poultry Max) as alternative to antibiotic can be used for improving performance of broiler chicken.
