This study aimed to investigate the effects of folic acid and vitamin B12 administration on the growth and wool traits in male lambs. A total of fifteen animals was used from 1st February 2015 to 30th April 2015, divided into three treatment groups. The first group served as a control, the second group received a folic acid dosage equivalent to 0.5 mg per kilogram of body weight per head, and the third group received a vitamin B12 dosage equivalent to 0.1 mg per kilogram of body weight per head. The vitamins were administered orally twice a week. The results showed a significant improvement (P<0.05) in final body weight, daily gain, and total weight gain in the vitamin B12 and folic acid groups compared to the control group. Additionally, there was a significant (P<0.05) increase in all wool characteristics, except for crimp number, in the folic acid group compared to the control group. The study demonstrated significant relationships between body weight and every aspect of wool quality except for fiber length. There was a significant (P<0.05) increase in the concentrations of growth and thyroxine hormones in the vitamin B12 and folic acid groups compared to the control group, particularly in the second and third months of the experiment. No significant difference in insulin hormone concentration among the groups was observed during the 90-day experiment. In conclusion, administering vitamin B12 and folic acid are orally administered twice a week to improve growth, increase hormone concentrations (thyroxine and growth hormone), and improve wool quality.
