Effect of rice based distiller dried grain solubles (RDDGS) with or without enzyme supplementation on egg quality parameters of commercial layer chicken

Abstract

A study was conducted in 240 commercial layer chickens (BV-300) at 26 weeks age were randomly allotted to 10 treatments with 6 replicates and 4 layers in each replicate. The birds were raised in cage system under uniform management. A standard layer ration (CP 18%, ME 2600 kcal/kg diet) was offered to birds. The test compound, RDDGS was supplemented at different levels (0, 5, 10, 15 and 20%) with or without Cocktail enzyme supplementation @ 250 gm/ton of feed. Birds were aclamatised to respective treatment diets for a week (26th week) before the commencement of the actual data collection. The feed and water should be provided adlib during the entire experimental period (4 periods of each 28 days from 27 to 42 weeks). Parameters such as egg quality parameters (Haugh unit, shell thickness, shell breaking strength, albumen index, yolk colour, yolk index) were estimated at 4 weeks interval. The results revealed that the overall egg weight and egg mass was significantly (p
