Final weight evaluation and carcass yield in water buffalos (Bubalus bubalis) in an extensive system, in the Iruña farm in the municipality of Panzós, Alta Verapaz, Guatemala.

Abstract

In the present work, the productive indicators, such as weight gain and yields of the carcasses, were evaluated in a lot of twenty water buffaloes (Bubalus bubalis), in the Iruña farm, located in the Polochic river valley, municipality of Panzós, Alta Verapaz The management of the buffalo began from the time of calving, identifying them by means of tattoo and earrings, weighings from birth to weaning and the final stage, as well as management practices already established in this livestock company, such as castration, deworming, etc. . The variables to be evaluated were: the weight gain from birth to the final marketing stage and gutter yields, performing a descriptive statistical analysis. The average weight gain per day was determined, resulting in 0.65 Kg. From birth to final weighing and an average gutter yield of 50.18% (hot) and 48.87% (cold). The time for the return of the invested capital is very important at the time of economically analyzing any animal exploitation, so the weight and age of the buffaloes were compared taking into account that they were managed under an extensive system and it was determined in this investigation that the average age was 22 months with 7 days, with an average weight of 472.8 kg. Due to the characteristics of the private trail where these buffalos were slaughtered, it was possible to determine the shrinkage between the hot gutter and the cold gutter, being 1.31 % applied to a normal data.
