PROXIMATE COMPOSITION OF SOME SELECTED ENERGY AND PROTEIN FEEDSTUFFS

Abstract

The study was conducted in Bauchi, Bauchi State to determine the proximate composition of some selected energy and protein feedstuffs. Feedstuffs for the analysis of proximate composition were obtained from commercial markets across Jos, Bauchi and Adamawa States. The feedstuffs were first cleaned from any foreign materials, milled and screened to fine particle size (< 250 µm) and samples were analysed for proximate composition. Analyses were conducted at Rico Gadu Laboratory Mayo Belwa Local Government Area of Adamawa State and National Veterinary Research Institute, Vom. The feedstuffs analyzed were grouped into (4) classes; Plant protein sources, Animal protein sources, energy sources and anti nutritional factors. The results of the analysis showed that the plant protein feedstuff had an average of 90.30-97.42%DM, 14.41-51.10% CP, 4.90-20.96% CF, 3.8-11.31% EE, 4.90-16.28% ash,28.55-58.00% NFE and 2740.82- 3229.20Kca/kgME. The Animal protein had an average 86.12- 93.0% DM, 31.20-41.15% CP, 2.13-2.80% CF, 9.80-13.79% EE, 4.90-18.94%ash, 10.11-44.90% NFE, 3004.00-3527.45Kcal/kgME. The energy source had an average of 85.00-91.54% DM, 6.00-15.64% CP; 2.60-13.08% CF, 2.24-17.00% EE, 1.08-7.25% ash, 45.19-83.88% NFE and 2878.67-3438.90 ME. Some of the anti- nutritional factors analyzed revealed that Sunflower had 23.82mg/100g Phytic acid, 9.86m/100g Tannin and 350mg/100/g oxalate. Tamber had 27.39mg/100g Phytic acid, 9.57mg/100g Tannin, 220mg/100g Oxalate. Wheat had 22.63mg/100g Phytic acid, 8.29mg/100g Tannin and 210mg/100g Oxalate. Soyabean had 25.41mg/100g Phytic acid, 13.62mg/100g Tannin, and 770mg oxalate. Sesame had 29.77mg/100g Phytic acid, 11.76mg/100g Tannin and 465mg/100g oxalate, while Acha had 17.48mg/100g Phytic acid, 4.00mg/100g tannin and 140mg/100g oxalate respectfully. It was concluded that the research gave an information on the availability and the nutrient levels of the energy feedstuffs which can as well substitute for the conventional ones which are expensive, unavailable or seasonal in distribution. It was therefore recommended that, the research can serve as a guide to others in the field of animal nutrition who may wish to find out the proximate composition of other feedstuffs yet to be investigated for their nutrient levels
