Abstract
The objective of current research was to evaluate lysozyme, bacillus amyloliquefaciens SC06 and tributyrin as an alternative
of enramycin in broiler chicken. Four isocaloric and isonitrogenous experimental diet contained either enramycin, lysozyme,
tributyrin or bacillus amyloliquefaciens SC06 were prepared. Three hundred mix sexed broiler chicks were distributed
into4experimental treatments with five replicates in each experimental treatment. Results showed that feed intake and feed
efficiency during finisher phase was not influenced by any treatment (P >0.05). Similarly, body weight gain was not influenced
by experimental treatments (P >0.05). However, dry matter digestibility was higher in tributyrin and enramycin as compared
to lysozyme and B.A SC06 (P<0.05). Lysozyme, B.A SC06 and tributyrin showed better ether extract digestibility as compared
to enramycin (P<0.05). Tributyrin reflected highest crude fiber digestibility as compared to enramycin, lysozyme and B.A
SC06 treatments (P<0.05). Slaughtering parameter represented that dressing %, breast meat weight %, relative heart weight %
and relative gizzard weight % did not differ in all experimental treatments (P>0.05). However, highest thigh meat yields %
was seen in enramycin treatment and tributyrin treatment (P<0.05). Based on performance parameters, it is concluded that
lysozyme, bacillus amyloliquefaciens SC06 and tributyrin can successfully replace enramycin in broiler finisher rations.
