Abstract: In the post-antibiotics era, probiotic, prebiotic and their combination are proposed as alternatives to antibiotic growth promoters in the modern poultry production. The objective of the present study was to evaluate the effect of in ovo injection of Lactobacillus acidophilus, MOS and their combination on the production performance of commercial broilers. On d 18 of incubation, 720 eggs were randomly divided into 5 experimental groups each with four replicates of 30 eggs each and were injected with different bioactive compounds viz., 0.2 ml of Lactobacillus acidophilus 3x107 cfu (T3); 0.2 ml of 0.5% Mannan-oligosaccharide (T4); 0.2 ml of Lactobacillus acidophilus 3x107 cfu + 0.5% Mannan-oligosaccharide (T5). The in ovo treatment groups were compared with non-injected control (T1); sham control group injected with 0.2 ml of Physiological saline (T2). After hatching, 20 day-old broiler chicks from each replicate was utilized for biological study. All chicks were reared under deep litter system up to five weeks of age under standard and uniform manage mental conditions in an environmentally controlled broiler house throughout the experimental period. Birds were fed with ad libitum pre starter, starter and finisher mash prepared as per as per BIS (2007) from 0-14 d, 15-21 d and 22-35 d of age, respectively. The data on bi-weekly body weight, body weight gain, feed consumption, feed conversion ratio (FCR) and liveability were recorded and statistically analysed. The results of the present study revealed that 5th week cumulative body weight and weight gain were significantly (P<0.01) improved in all in ovo treated broilers irrespective of the bioactive compound when compared to control birds. But, there was no significant difference between in ovo treatment groups. The cumulative feed consumption, FCR and liveability of broilers up to five weeks of age were not influenced by in ovo supplementation of Lactobacillus acidophilus, MOS and Lactobacillus acidophilus + MOS between treatments. But there was marginal improvement in the liveability of broilers. Based on the results, it can be concluded that the in ovo supplementation of Lactobacillus acidophilus and MOS either independently or in combination has beneficial effect on growth and survivability of commercial broilers.
