ESTIMA TION OF CRUDE FIBRE AND CRUDE PROTEIN IN COMMERCIAL POUL TRY RA T.JONS AND SOME IMPORT ANT FEED INGREDIENTS

A total of 1218 samples relating to compound poultry rations and feed ingredients were analysed for crude fibre content. The crude fibre contents ranged between 4.79 ± 0.75 and 5.69 ± 2.03 with CV ranged between 14.89 and 35.68 for six categories of commercial poultry rations including chick starter, grower mash, layer mash, broiler starter, broiler finisher and breeder mash. The crude protein contents estimated on 2679 feed samples of compound poultry feed and feed ingredients ranged between 15.86 ± 1.41 and 18.63 ± 1.67, while the CV ranged from 8.89 to 10.99. The crude fibre and crude protein contents in feed ingredients, agricultural and animal byproducts are specific to each item and the values are based on chemical analyses which are broadly within values prescribed by nutritional standards.
