Effect of beniseed hulls treated with and without the maxigrain® enzyme on the production and quality of eggs of Black Nera laying hens

Abstract

The aim of this research was to study the effect of beniseed hulls treated with and without the Maxigrain® enzyme on the production and quality of eggs of Black Nera laying hens. The study involved nine diets with approximately 16% protein were formulated, including: CONT: soybean meal-based basal diet, WBSH15: 15% beniseed hull without enzyme, BSH15: 15% beniseed hull with enzyme, WBSH30: 30% beniseed hull without enzyme, BSH30: 30% beniseed hull with enzyme, WBSH45: 45% beniseed hull without enzyme, BSH45: 45% beniseed hull with enzyme, WBSH60: 60% beniseed hull without enzyme, BSH60: 60% beniseed hull with enzyme. The addition of Maxigrain was at a level 0.01%. A total of 189 Black Nera hens were used in this experiment, divided into 9 groups with 21 hens each replicated 7 times in a completely randomized design. They were fed for 12 weeks. The results showed that hens fed BSH60 (P<0.05) had higher change of body weight, while those fed WBSH45, WBSH60, and BSH60 diets (P<0.05) had higher feed intake. The control diet, BSH15, and BSH30 groups (P<0.05) had better egg production metrics, while WBSH 60 and BSH60 showed improvements in various egg quality parameters. Overall, it was recommended to use BSH15-30 diets for Black Nera hens for optimal egg quality production
