Slaughter and carcass yields of the Philippine carabao (PC),<br />

Philippine carabao x Murrah F1 (PMF1) and F2 (PMF2)<br />

and Philippine carabao x Nili Ravi F1 (PRF1) were<br />

investigated. A total of 37 water buffaloes, 25-132 mos old,<br />

weighing 278-672 kg, slaughtered and fabricated into standard<br />

wholesale and retail cuts. The yield of each by-product and<br />

wholesale cuts were determined and correlated to the live<br />

weight and age of water buffaloes. The economic value of<br />

the slaughter and carcass yield of each breedtype was<br />

determined. Among the breedtypes, PMF1 had the highest<br />

average live weight of 480.50 kg while the PC had the<br />

lowest with 343.18 kg. PMF1 had heavier hot carcass<br />

(249.54 kg) and chilled carcass (242.96 kg) than other<br />

breedtypes. The carcass of PMF1 had the highest percent<br />

lean, lowest percent fat and highest chilled carcass weight.<br />

The percent lean in the carcass increased (r=0.554) while<br />

the percent fat decreased (r=-0.444) as the animals get<br />

heavier. The percent fat in the carcass tended to increase<br />

(r=0.388) as the water buffaloes get older. PMF1 had the<br />

highest estimated sale of Php18,644.89 per head, while PC<br />

had the lowest with Php12,586.45. PMF1 had the highest<br />

estimated sale per kg live weight of Php38.00 while PRF1<br />

had the lowest with Php36.52. The results of the study<br />

suggest that Philippine carabao x Murrah crossbreds can<br />

give higher monetary value to the farmer from slaughter and<br />

carcass yields, with almost the same meat quality as the<br />

Philippine carabao. The crossbreds have genetic potential<br />

to grow faster than Philippine carabaos; thus, they can<br />

reach optimum slaughter weight at a much shorter time or at<br />

a younger age with a relatively tender meat and less amount<br />

of trimmable fats.<br />

ABSTRACT OF RESEARCHES ON<br />

<strong>THE</strong> <strong>PHILIPPINE</strong> <strong>WATER</strong> <strong>BUFFALO</strong><br />

Data were obtained from two hundred four native Philippine<br />

carabao bulls slaughtered at the Purefoods, Inc.<br />

slaughterhouse. The data were grouped according to ages,<br />

body weights and scrotal circumferences. Age of carabao<br />

bulls ranging from 2015 years was grouped into one and<br />

two years class intervals. The body weight ranging from<br />

231.8 to 547.0 kg and were grouped into 40 kg class<br />

intervals. Likewise, scrotal circumference (20 to 28 cm)<br />

was grouped into one cm class intervals. The classes<br />

were resorted to due to difference in the environmental<br />

factors and sources of animals. Age relationship with<br />

testicular measurements (weight, volume, length and width),<br />

seminal vesicle measurements (weight and volume) and<br />

scrotal circumference were quadratic and the shape of the<br />

graphs curvilinear. The curvilinear correlation coefficients<br />

were high, 0.967, 0.968, 0.939 and 0.932, respectively for<br />

average testicular weight, volume, length, width, for age<br />

and scrotal circumference (R) was 0.979; among age and<br />

seminal vesicle weight and volume (R) more 0.975 and<br />

0.974, respectively. All curvilinear correlations were lightly<br />

significant (P< 0.0001). The difference between right and<br />

left testes and seminal vesicle based on age classes were<br />

however not significant. The curvilinear regression equation<br />

values for estimating scrotal circumference and right, left,<br />

average and total testicular weight volume, length, width,<br />

seminal vesicle weight and volume measurements, all as<br />

dependent variables, based on age classes as independent<br />

variables were tabulated. All the parameters of regression<br />

equation values were highly significant (P
