Background and Aim: Recent advancements in sexed semen technologies, particularly in sorting techniques, have enhanced the ability to selectively determine the sex of offspring in cattle. This study, conducted by ICAR-KVK Mamnoor under PVNRTVU, served as a front-line demonstration in adopted villages of the Warangal and Hanmakonda districts in Telangana. It aimed to evaluate the conception rates and sorting efficiency of sexed semen in comparison to conventional semen (CS) under field conditions.
Materials and Methods: In this study, artificial insemination was conducted using sex-sorted semen (SS; n = 200) and conventional semen (CS; n = 200) during spontaneous estrus, precisely 16 to 18 hours after the onset of estrus signs. The objective was to compare conception rates in crossbred cows under field conditions. Several parameters were recorded for each cow, including the percentage of conception rates and the number of female and male calves born
Results: Conception rates for sex-sorted semen and conventional semen were recorded at 55% and 53%, respectively, indicating a statistically significant difference (p < 0.01). The percentages of female and male calves born from sex-sorted and conventional semen were 89% and 73%, respectively, with sexed semen showing a significantly higher percentage (p < 0.01) compared to conventional semen.
Conclusion: The number of female calves born and the conception rate were greater with sexed semen (SS) than with conventional semen (CS), with the duration of estrus being a significant factor affecting conception under field conditions. This study highlights the advantages of utilizing sexed semen in field settings to boost the number of female calves and reduce the burden of male calves for farmers.
