<br/><br/> CRUZ, EMILIO MANUEL, University of the Philip-pines at Los Bafios, April, 1982. Farmers' Perceptions and Attitudes Toward Carabao Breeding Practices and the Reproductive Performance of Cara-cows Bred by Artificial Insemination or Natural  Mating  Under Farm Conditions. <br/>Major Professor: Dr. Vicente G. Momongan<br/>The study was conducted to ascertain farmers perceptions, attitudes and practices toward carabao breeding methods and to determine the reproductive performance of carabaos bred by natural or artificial means under farm conditions. The study was conducted in the different towns of Nueva Ecija. <br/>One hundred-three caracow owners were purposively selected and interviewed with the use of structured questionnaire. Likewise, the caracows being raised were considered as the experimental animals.<br/>Findings revealed that majority of the respondents were knowledgeable on the following breeding management practices breeding receptiveness, manifestations of estrus, commencement of estrus, estrus duration and estrous cycle. <br/>There was no socio-demographic variable found to be related to the attitude towards artificial breeding. The findings revealed that the estrous interval of 83 cycles had a mean of 21.88 + 6.52 days (S.D.) with a range of 7 to 33 days. <br/>With regards to the number of services per conception, the naturally bred animals required 2.06 services per conception, with an average conception rate of 71.43 percent. On the other hand, caracows that were artificially bred required 2.89 services per conception with an average conception rate of 57.58 percent. The study showed no significant differences in the number of services per conception, rate, and respondent's attitude towards the two breeding practices.<br/>
