Descripción
Due to inefficient use of nitrogen (N) in rumen, ruminants have a low efficiencyof N utilization. A large part of ingested N is excreted into the environment without being usedby animals. The objective of this study was to analyze the efficacy of a treatment combining malicacid and heating (MAH) to protect the protein in sunflower seeds (SS) and meal (SM) against rumendegradation and to improve the growth of lambs. Two high-cereal concentrates, either includinguntreated or MAH-treated SS and SM, were fed to two homogeneous groups of lambs. Further, feedintake, diet digestibility, and lamb growth from 14 to 26 kg body weight were assessed. Anin vitrotrial indicated that the MAH-treatment modified the rumen fermentation pattern of both SS andSM, and it reduced the NH3-N concentrations for SM. However, there were no significant effects ofthe MAH-treatment on feed intake, diet digestibility or growth of lambs. The hot carcasses of thelambs fed the MAH-treated concentrate were 7.9% heavier but not statistically different to those ofthe untreated group. In conclusion, under the conditions of the present study the MAH treatment didnot improve the growth performance of lambs.
