| Resumo: |
The aim of this study was to evaluate the performance of sheep supplemented with phosphorus (P) using carcass traits and analysis of 12th rib. Twenty male lambs weighing 13.88 ± 2.51 kg and grazing Andropogon gayanus pasture were divided in two treatments of 10 animals each. In group P, animals were supplemented with 3 g phosphorus/animal/day, while in group NP no P supplementation was given. After 82 days the animals were slaughtered and carcass measurements were taken. The 12th rib was also removed for analysis. No significant differences in body weight, carcass yield, or commercial cut weights were found between both treatments, except for liver and kidneys that were heavier in the supplemented group (p=0.0954). The 12th rib analysis showed that the group P had higher rib, bone, and muscle weights when compared to animals not supplemented with P. Other measurements such as carcass fatness and rib eye area were not significantly affected by treatments as well as contents of crude protein, ether extract, ash and P. It was shown that P supplementation improved performance in young sheep, including bone and muscle tissue and liver and kidney weights.
