Survey on Artificial Insemination Practices in Shikalbaha Union of Karnafuli Upazilla, Chattogram

Abstract

The research was carried out in Shikalbaha Upazilla located in the Chattogram district. The aim was to investigate the of cattle artificial insemination (AI) technology practices, taking into account factors such as general information of the farm and milk production based on genotypes. The conception rate of artificial insemination was also dependant on farm type. Data was gathered through a questionnaire administered to 15 farms during the timeframe of July 2023 to August 2023. The findings reveal that out of the surveyed farmers, 100% of them are inseminated using semen of Govt. sources. Four genotypes of cattle was found where HF(0.75)×L(0.25) and J(0.50)×L(0.50) exhibited the highest daily average milk yield (10-12L) in 40% of farms. Consequently, the total conception or success rate was calculated to be 68.29% whereas higher conception rate was found in A type farm. The observed lower success rate is potentially attributed to factors such as temperature, subpar semen quality, and the presence of inexperienced inseminators. Enhancement in the conception rate could be achieved by ensuring the provision of high-quality semen and skilled inseminators to the farmers.
