Nutritional inadequacies and nutrient imbalance especially of vitamins may lead to impairment of male reproduction and leads to poor semen quality and requires exogenous supplementation to improve semen quality and fertility of cryopreserved semen in cattle bulls. A group of eight crossbred bulls (75% Holstein Friesian, 25% Sahiwal, 3-5 years old) maintained at dairy farm GADVASU, Ludhiana apparently healthy showing no visual sign of testicular atrophy and reduced libido but exhibited poor semen quality i.e. (watery ejaculates with poor sperm concentration less than 500 million per ml, initial sperm motility <60% and poor freezability). Bulls were divided into two groups (n=4 in each). Group- I bulls were administered Vitamins (Vitamin A (120000 IU); Vitamin D3 (60000 IU); Vitamin E (480 mg); and Nicotinamide (30 mg) and Vitamin H (500 mcg)) orally for consecutive seven days (INTAVITA NH oral dose 10 ml ) in first treatment and after fifteen days of first treatment the second dose of Vitamins viz. Vitamin A (2500000 IU); Vitamin D3(250000 IU); Vitamin E (1000 IU) was administered through intramuscular route (INTAVITA 10 ml, INTAS). Group II was taken as control group. Semen collection was suspended during treatment and for at least one month after post treatment. The various seminal parameters viz. volume (ml), consistency (grade as 0-3), mass activity (graded as 0-4), sperm concentration (million/ml),initial motility(%), prefreeze motility (%) and post thaw motility (%) were recorded before and after treatments. The data was statistically analyzed using standard t-test. The results showed significant increase in sperm concentration, mass activity, initial motility and semen acquired freezability (Pre-freeze motility 60.66 ± 1.64%; post thaw motility 46.33 ± 0.80%) in treated group as compared to control. It is concluded that exogenous administration of vitamins has shown marked improvement in semen quality of crossbred cattle bulls and therefore, it is suggested that periodic monitoring of micronutrients supplements in diet in recommended amounts is essential to maintain the semen quality of crossbred bulls.
