Effect of Dietary Inclusion of Soybean Hulls in the Diet on Feed Proximate Analysis, Egg Quality Parameters and Economics during Peak Egg Production Stages in Laying Hens

Abstract

The study was designed to determine the effect of varying levels of soybean hulls inclusion in the diet of brown layer on, feed proximate analysis, egg quality, and economies during peak egg production period with different phases (phase-1=week 29 to 32, phase-2=week 33 to 36, and phase-3=week 37 to 40). One hundred and sixty golden misri (Brown) laying hens of age 28 weeks were sourced and reared for 40 weeks. There were 4 groups with 4 replicates per group containing 10 birds each. Corn-soybean meal diet (Basal Diet) was offered to the control group (A), while groups B, C, and D were fed the basal diet with 3, 6, and 9 % soybean hulls (SH) respectively. Results showed higher(P<0.05)crude fiber, ash, cellulose, and hemicellulose content for diets containing soybean hull (SH) at 3, 6, and 9% compared to the basal diet. Egg weight and egg quality parameters during different phases were not affected among the treatment groups. Total revenue and profit during all phases (phases 1, 2, and 3) while cost-benefit ratio during phase-1 and 2 were recorded significantly higher for the control group than all other treatment groups.It is concluded that the effect of different levels of soy hulls in diet did not affect egg weight and egg quality parameters during different phases but economic parameters were significantly higher (P<0.05) amount in the control group than all soybean hull treatment groups. Among soybean hulls groups, 3% and 6% SH group showed better results than 9%SH group.
