    The study was undertaken to investigate the production system of swine in Rangamati and Khagrachari districts for a period of 60 days from 17th December’ 2008 to 16th February’ 2009. Production system of swine i.e. housing, feeding, breeding, diseases prevalence, vaccination program, bio-security, marketing of swine with socio-economic status and constraints of pig rearing were investigated during the study period. It was revealed that mostly poor and landless people reared pigs (54.71%) where most of them were illiterate (43.39%). Rearing systems they followed, were the free range (43.40%), Tin shed housing (24.53%), Fencing (20.75%) and Neck tethering (11.32%). At Rangamati pig farm the average litter size, birth weight, post- weaning weight, and weaning period were 9.46, 1.7kg, 8.86kg, 41.66 days, in family level farming it was 7.57, 1.33 kg, 7.10 kg, 44.36 days respectively. The prevalence of diseases was Hemorrhagic septicemia (13.73%), Pneumonia (17.64%), Coccidiosis (21.57%), NS diarrhea (37.25%) and others (9.8%) in Rangamati pig farm.

    The study was conducted to evaluate the success rates of artificial insemination both in Pahartali and Khagrachari District AI center. The study period was December 2008 to February 2009.The average success rates of AI in Pahartali and Khagrachari district AI center were 53.80 and 39.75%, 54.95 and 42.90 %, and 51.86 and 50.87%, in term of breeds, parity and semen type, respectively. The highest conception rate was observed in L×F×F breed in Pahartali (70%) and in local × Fresian in Khagrachari (52%). The lowest CR was observed in L×F (41.26%) and L×S (44.11%) breeds in Pahartali and L×S (29.68%) Khagrachari District AI center. In Pahartali, the highest CRs were found in terms of parity 63.88% (parity number 5) and 51% (parity number 4). In both Pahartali and Khagrachari, the lowest CR was observed in cows having parity number 2, and the result was 51 and 29.34 %, respectively. The RCC semen produced good result (66.66% CR) in Pahartali and (77.50% CR) in Khagrachari. The poorest result was observed in L×F type semen in Pahartali (40%) and Khagrachari (12.25%).
