Performance, carcass yield, and meat quality of buffalo (Bubalus bubalis) fed on diets with different levels of concentrate
The objective of this study was to evaluate the influence of diets with increasing concentrate levels on performance, carcass characteristics, and meat quality of Murrah buffaloes in feedlot. Twenty-four animals, with an initial body weight of 240 ± 50.5 kg and mean age of 9 months, were distributed to four treatments: 20%, 40%, 60% and 80% concentrate. After 114 days, the animals were weighed, slaughtered, and meat quality and performance data were submitted to analysis of variance and regression. The dry matter intake and average daily gain increased linearly. The final body, hot carcass, and cold carcass weights responded linearly to increases in concentrate level. The subcutaneous fat thickness, protein, and ether extract of meat increased linearly with an increase in concentrate level. The colour parameters, cooking losses, and shear force of the meat were not affected by increasing the concentrate. The inclusion of concentrate in feedlot diets increases performance, characteristics of carcass, and meat quality of Murrah buffalo in a feedlot.
期刊介绍:
The South African Journal of Animal Science is an open access, peer-reviewed journal for
publication of original scientific articles and reviews in the field of animal science. The journal
publishes reports of research dealing with production of farmed animal species (cattle, sheep,
goats, pigs, horses, poultry and ostriches), as well as pertinent aspects of research on aquatic
and wildlife species. Disciplines covered nutrition, genetics, physiology, and production
systems. Systematic research on animal products, behaviour, and welfare are also invited.
Rigorous testing of well-specified hypotheses is expected.
