Scholarcy highlights

  • In-feed probiotics are becoming attractive alternatives to antibiotics in the poultry industry due to the ever-growing strict prohibitions on antibiotic growth promoters in animal production
  • In this study to evaluate the effect of probiotics on the growth performance of broiler chickens on body weight, body weight gain, feed intake, and feed conversion ratio were recorded
  • Bodyweight of the broilers’ week wise showed that at the first week of treatment the body­ weight of broilers with Probiotic supplemented diet results numerically higher body weight than without pro­ biotic despite the Bodyweight of T2 and T4 treatment groups were found significantly different from T1 and T3 treatment groups
  • The current study shows that the data on total feed intake, total body weight gain, and feed conversion rates in broilers were influenced by probiotic feed treatments
  • The present findings indicated a significantly bet­ ter feed conversion ratio on probiotic supplementa­ tion in the diet of commercial dual-purpose chickens and unlike the result reported by Mohan et al there were no significant differences in the final weight and FCR among the treatment groups with different concentrations of pro­ biotic
  • The finding of the current study has shown that the two screened probiotics, Lactobacillus paracaseis sparacasei and Lactobacillus rhamnosus, were beneficial for the growth performance by improv­ ing body weight gain, feed conversion ratio, feed intake, and positively affects the growth of the chicken
  • Further studies characterized by a systematic approach and the use of advanced technologies will be needed to fully compre­ hend the mechanisms of action of the probiotic strains and to better assess their use in poultry nutrition
