Abstract
The present study was designed to estimate the production economics of different semen dosages from buffalo bulls. Since, understanding the economics of superior sperm dose production and their efficiency in relation to fertility in buffaloes is important for sustainable and efficient germplasm production. For this study, a total of 3083 ejaculates of 14 Murrah Buffalo bulls of ICAR-Central Institute of Research on Buffaloes, Hisar were considered. To estimate the economics of semen dose budgetary analysis was used. The average number of ejaculates per bull was 220 with semen volume of 2.58 ml and 1065.07 million spermatozoa per ejaculate. The conversion of total sperm count into straws with 20, 16 and 12 million spermatozoa found that bull was able to produce 30227, 37783 and 50378 sperm doses, respectively. The net income accrued from the sale of semen with 20, 16 and 12 million spermatozoa were found to be 115148.64, 228498.72 and 417415.51, respectively. The cost and returns per dose of semen production were estimated separately for 20, 16 and 12 million spermatozoa. The net cost per semen straw was found to be Rs. 11.19, Rs. 8.96 and Rs. 6.72 for semen doses with 20, 16 and 12 million spermatozoa, respectively. The net profit was highest for the semen dose with 12 million spermatozoa (Rs. 8.28 per dose) in comparison with semen dose with 16 (Rs. 6.04 per dose) and 20 (Rs. 3.81 per dose) million spermatozoa. Thus, a reduction in spermatozoa per semen straw shall enhance semen production and reduce the cost of per dose semen production which shall eventually lead to more production as well as wider dissemination of superior buffalo germplasm to the buffalo stakeholders.
