Abstract

Success rate of artificial insemination (AI) in cattle is known to decrease over the years of its continuous adoption. Objective of this study was to assess the awareness and relevant practices of livestock inspectors providing AI service, on the declining success rate, emerging fertility issues and possible remedies. The study involved a pre-structured questionnaire survey preceding refresher training for LIs. Among 170 participated, success rate of AI assessed was 36.29 %. Reported incidence of prolonged oestrus in the herd was 38.61±2.01% and double insemination was carried out in 27.27 % of oestrus. Preferred time for first AI was 12.94±7.26 hours from the onset of oestrus, site of semen deposition was anterior cervix or uterine body in 40.47 % and 32.74 % respectively and the actual process of AI took an average of 41.30±3.50 seconds per animal. Regarding the emerging fertility issues in AI bred animals, majority of inseminators were aware of and youngsters were more concerned for adoption of remedial measures. To conclude, present success rate of AI in cattle is less and majority of the informants, predominantly youngsters were more aware of the declining success rate, associated emerging fertility issues and the need for suitable remedial measures.
