Performance of growing crossbred Friesian calves fed biological treated roughages and concentrate 2 - Blood constituents and carcasses characteristics
Abstract: The aim of this study was to investigate the effect of feeding biological treated roughages and concentrate feed mixture in the rations of growing crossbred Friesian calves some blood constituents and carcasses characteristics. The experiments extended for 183 days and were carried out on forty eight crossbred Friesian calves of 6 -7 months old and 189.17 ±3.58 Kg live body weight (LBW). Animals were divided into 3 groups of 16 calves; each group was divided into two subgroups (8 calves each). The experimental groups allotted randomly into six rations: control (R1, R3 and R5): 2% of LBW. CFM and ad-libitum straws of wheat, bean and clover, respectively, while R2, R4 and R6 included 2% CFM of LBW and biological treated (Trichoderma harzinaum F-418 fungi) previous straws ad-libitum, respectively. Blood constituents, dressing percentage and carcasses characteristic were determined. Results indicated that, the activity of serum transaminase enzymes, serum total protein, albumin glucose and cholesterol concentrations were increased significantly (P<0.05) with biological treated straws containing rations compared with other treatments. No significant differences were found among the experimental treatments in serum globulin and creatinine urea-No Dressing percentage was significantly (P<0.05) higher for biological treated roughages than other control groups. Eye muscle (Longissimus dorsi) area, water holding capacity (WHC), and tenderness, of biological treated groups were higher than those received the control groups. pH values and coluor intensity of the eye muscle of calves fed biological treated roughages were significantly (P<0.05) less than those fed control. The chemical composition of 9 to 11th ribs of eye muscles showed significant (P<0.05) effect of biological treatments, protein percentage was relatively higher in biological treated groups than those fed the control groups, while no significant differences were found in the fat and ash percentage among all the treatments. It could be concluded that, feeding biological treated (Trichoderma harzinaum F-418 fungi), wheat, bean and clover straws ad-libitum with 2% of LBW concentrate feed mixture (2% of LBW of growing crossbred Friesian calves), resulted in superior dressing percentage and better carcasses characteristics, as compared with control groups could be recommended.
