Growth rate, metabolic activity and reproductive performance of buffalo bulls administered with different levels of vitamin c

Abstract: The study was conducted to investigate the effect vitamin C (VC) treatment on growth rate, some testicular measurements, semen characteristics and blood parameters. Fifteen buffalo bulls aged 21 - 28 months with average initial body weight 305.8 ± 2.5 kg. were divided randomly into three comparable groups (5 animals in each). Group C served as a control group without any treatment while, groups VC1 and VC2 were subjected to vitamin C treatment via intramuscular injection at the rate of 6 and 3 ml/head/week, respectively. Differences in live body weight (LBW) between VC treated groups and group C were highly significant (P < 0.01). Groups VC1 and VC2 attained a significant increase in DWG in comparison with that of the control group C.
Concentrations of blood total proteins or its fractions (albumin and globulin) were significantly (P<0.05) higher in group VC1 compared to those of group C or VC2. Also, group VC1 had significantly(P < 0.05) higher content of blood glucose, BUN, cholesterol and creatine in comparison with other
groups. Group C showed less content of creatinine as well as transaminases activity (ALT and AST) than that of VC treated groups. Concentrations of T4 increased to 9.53 .g/dl on average at the 3rd phase of growth with superiority of its level (9.87 .g/dl) in VC1 group. Similar trend was observed for testosterone concentration.
Groups VC1 and VC2 achieved greater testicular length and circumference than that of group C, those traits were maximized in VC treated groups by reaching the 3rd stage of growth. Higher testicular volume was observed for the treated groups VC1 and VC2 by 9.85% and 13.39% over that of group C at the 3rd stage of growth. The least values of semen volume were obtained by group C throughout growth stages whereas the maximum volumes were achieved by group VC1. Higher libido was exhibited by group VC1 compared to group VC2 and group C. Groups VC1 and VC2 achieved higher sperm output by 17.43%, and 11.10% , respectively in comparison with group C. Differences in sperm abnormality between groups varied significantly (P < 0.05) within sampling stages. The highest percentage of live sperms was attained by group VC1 (64.9%) at 3rd stage of growth. It can be concluded that higher dose of vitamin C injection (6 ml/head/week) had promoted growth of buffalo bulls, enhanced its metabolic activity hence improved male libido, output of semen and its physical characteristics.
