Laying performance of Noiler chickens fed with different biotic additives

Abstract

The focus of different live additives (prebiotic, probiotic, and synbiotic) is to enhance the immune status and improve the performance of  livestock. A total of 128 Noiler female point of lay were used in an experiment arranged in a completely randomised design. The birds were randomly distributed into four treatments with eight replicates of four birds each. Experimental treatments consisted of prebiotic, probiotic, synbiotics and control at 1g inclusion rate into kg of feed. Egg production parameters (Hen day performance, age at first lay, age at peak production, feed intake and mortality) and haematological indices were evaluated. The experiment lasted for a period of 22 weeks. Data collected were subjected to one-way analysis of variance. The result obtained revealed significant (P<0.05) differences across the treatments. The treatment that contained probiotic at 1g/kg of feed produced an average hen day of 64.74%, with 129.1g per day of average feed intake and 2.02 feed/egg weight ratios and recorded the best performance of all the other treatments. However, liveability was one hundred percentages throughout the period of the experiment.  Hence, it could be concluded that probiotic enhanced Noiler layers performance.
