Pig rearing is the fastest growing component of animal husbandry, which provides livelihood and nutritional security to the rural sector in Kerala. But, the lack of availability of superior quality germplasm remains as one of the challenges in this sector. Artificial insemination (AI) is the most established scientific procedure to disseminate superior germplasm. The present study was conducted in Large White Yorkshire (LWY) pigs maintained at the Centre for Pig Production and Research, Mannuthy for a period from March 2015 to August 2016 to evaluate the success rate of AI. During this period, 90 weaned sows and five LWY boars were identified for the experiment. The breeding boars were trained lor semen collection using females in heat and semen was collected twice in a week, regularly by gloved hand technique into conical flask with Buchner's funnel. A total of 108 ejaculates were obtained from each boar. After preliminary examination, the neat semen was diluted (1:15) with commercial extender (NBSE, NRC on pigs, ICAR, Goa) and stored at 17°C. The sows with standing heat were inseminated (100 ml) using pig catheter consecutively for three days. The non-cycling pigs were diagnosed for pregnancy after 35-45 days by Doppler method. The study recorded 92.22 per cent conception rate for AI 91.35 per cent for natural service. The conception rate, litter size at birth, litter weight at birth and litter size at weaning were also recorded and the parameters did not differ significantly between AI and natural service. The results reiterate the importance of AI technique and it can be extended to the field levels which in turn contribute to the economic benefit of fanners. [ABSTRACT FROM AUTHOR]
