      ruminants for nutritive evaluation.

AB  - AIM: To evaluate some forage feeds of ruminants in terms of their carbohydrate 
      (CHO) and protein fractions using Cornell Net Carbohydrate and Protein System 
      (CNCPS). MATERIALS AND METHODS: Eleven ruminant feeds (six green fodders - maize, 
      oat, sorghum, bajra, cowpea, berseem and five range herbages - para grass, guinea 
      grass, hedge lucerne, setaria grass and hybrid napier) were selected for this 
      study. Each feed was chemically analyzed for proximate principles (dry matter, 
      crude protein [CP], ether extract, organic matter and ash), fiber fractions 
      (neutral detergent fiber, acid detergent fiber, acid detergent lignin, cellulose 
      and hemicellulose), primary CHO fractions (CHO, non-structural CHO, structural 
      CHO and starch) and primary protein fractions (neutral detergent insoluble CP, 
      acid detergent insoluble CP, non-protein nitrogen and soluble protein). The 
      results were fitted to the equations of CNCPS to arrive at various CHO (CA - fast 
      degrading, CB1 - intermediate degrading, CB2 - slow degrading and CC - 
      non-degrading or unavailable) and protein (PA - instantaneously degrading, PB1 - 
      fast degrading, PB2 - intermediate degrading, PB3 - slow degrading and PC - 
      non-degrading or unavailable) fractions of test feeds. RESULTS: Among green 
      fodders, cowpea and berseem had higher CA content while except hedge lucerne all 
      range herbages had lower CA values. CB1 content of all feeds was low but similar. 
      All feeds except cowpea, berseem, and hedge lucerne contained higher CB2 values. 
      Oat among green fodders and hybrid napier among range herbages had lower CC 
      fraction. Feeds such as bajra, cowpea, berseem and the setaria grass contained 
      lower PA fraction. All green fodders had higher PB1 content except maize and 
      cowpea while all range herbages had lower PB1 values except hedge lucerne. Para 
      grass and hybrid napier contained exceptionally low PB2 fraction among all feeds. 
      Low PC contents were reported in oat and berseem fodders. CONCLUSION: Based on 
      our findings, it was concluded that feeds with similar CP and CHO content varied 
      significantly with respect to their CHO and protein fractions. Due to lower CC 
      fraction, oat and hybrid napier were superior feeds in terms of CHO supply to 
      ruminants. Similarly, among all feeds oat and berseem had a lower PC fraction, 
      thus were considered good sources of protein for ruminants.
