FEEDING VALUE OF RICE WASTE FOR LAYERS AND ITS EFFECT ON EGG QUALITY

Abstract

Rice waste, a rice milling by product starter and grower ration were transferred to contains mostly broken rice along with isocaloric and isonitrogenous layer rations polishings, bran and husk. The annual containing 0, 10,20 and 40% rice waste Dry avaitability in India was estimated as 5 million matter, 90.53%; Crude protein ,7.8%; Crude tonnes (Devandra ,1978). Rice waste with a fibre, 0.96%; Ether extract ,2.78%; Total ash, crude protein level ranging from (7% 3.2%, and NFE, 85.26%) replacing maize (wl (Ravindran and Blair, 1991) to 9.4% w) and the biological trial was conducted in (Crampton and Harris, 1969) and low fibre a completely randomised design with four level of 3.14% (Singh and Marwha, 1968) and replicates for each treatment from 18-22 ME above 3200 KcalIKg (Hubbell, 1991; weeks of age. The proximate composition Ravindran and Blair,loc.cit.) can be (AOAC, 199C), Calcium (Talapatra et a/., considered as a potential energy source for 1940) and phosphorus (Fiske and Subbarow, chicken. Further the low cost and continuous 'I 925) of the ration were estimated. The availability throughout the year, makes rice ingredient and chemical composition. of the waste as an ideal substitute for maize in the rations are given in Table 1. The effect of diet of chicken. To arrive at anEptimal level including Cice waste in layer ration was of inclusion of rice waste in the diet of layers, assessed in terms of mean body weight at a biological trial was conducted in layers housing and at 20 weeks of age, age at first during early stage and egg quality studies egg, age at 5 and 50% egg production, feed were carried out at 22" week
