The histological analysis of the proventriculus and gizzard of broilers fed wheat bran based diet supplemented with natuzyme and maxigrain

Abstract

This experiment was carried out to evaluate the effect of wheat bran based diet with or without commercial enzyme supplementation on the proventriculus and gizzard of Arbor acres broilers. The design of the experiment was a completely randomized design (CRD) with four treatments: T1- wheat bran based diet with no enzyme, T2- wheat bran based diet with Natuzyme, T3- wheat bran based diet with Maxigrain and T4- wheat bran based diet with Natuzyme and Maxigrain. One hundred and forty-four (144) one- day old unsexed Arbor Acre chicks were used in the trial. Performance record, carcass record and histological analysis were carried out. The dietary treatment had significant difference (p<0.05) on the average feed intake of the birds. The slaughtered weight was higher in birds fed T4. Visceral weight, weight of filled gizzard and weight of empty gizzard were affected. Histological analysis showed inflammation and degeneration of the structure of the proventriculus and gizzard of those birds fed with enzyme supplement.
