Non-starch Polysaccharides and Phytate Phosphorus Content of Commonly Available Poultry Feed

A study was conducted to find out the Non-starch polysaccharides (NSP) in terms of cellulose, hemicellulose, Neutral Detergent Fibre (NDF), Acid Detergent Fibre (ADF) and phytate phosphorus content of locally available poultry feed ingredients in and around Namakkal area. The mean NDF (%) of feed ingredients varied from 9.55 in maize and 11.64 in soyabean meal (SBM) to 45.88 in sunflower meal (SFM) and 53.54 in deoiled rice bran (DORB). While the ADF (%) content was higher in SFM (33.08) and DORB (24.06), it was lower in others. SFM contained highest cellulose content of 21.85 %. The mean NDF and ADF contents of broiler starter and finisher diets were 16 and 2 % respectively. The mean hemicellulose content of broiler starter and finisher diets were 13.59 % and 14.24 % respectively. The mean phytate phosphorus content of DORB was 1.39 % while that of SFM was 0.73 %. *Part of M.V.Sc thesis of the first author submitted to Tamilnadu Veterinary and Animal Sciences University, Chennai-51. 1Asst Professor, University Research Farm, 2Professor and Head, Dept of Animal Nutrition, 3Associate Professor, 4Professor and Head, AFAQCL, 5 Dean, VCRI, Namakkal, 6Asst Professor, DEE.
