This work aimed to use guar korma meal in concentrate feed mixture(CFM) for growing buffalo calves rations.The trial was carried out at Animal House of Animal production Research Institute and Al-Manar Company Station. Thirty male buffalo calves averaging 176.9 Kg LBW were chosen and divided into six similar groups. The groups of animals were randomly assigned to receive six experimental rations containing CFM which included guar Korma at the rate of 0, 3.3, 6.7, 10.0, 13.3 and 16.7% in rations A,B,C,D,E and F, respectively. These percentages of guar korma cover 0,10,20,30,40 and 50% of CFM protein content. All animals received CFM, berseem hay (BH) and wheat straw (WS) at the rate of 70:20:10, respectively. The feeding trial lasted 210 days, during which live body weights were recorded beside feed intake. Economical efficiencies were calculated for each ration. In addition, six digestibility trials were conducted to determine digestibility and nutritive values of the experimental rations. Samples of blood were taken to measure some blood parameters. The results obtained can be summarize as follows: 1) The chemical composition of different experimental rations were almost similar in DM, OM, CF,CP and NFE contents, with somewhat higher percentage of EE and Ash associated with increasing guar korma levels. 2) Increasing guar korma level in the experimental rations tended to significantly (P |
