N2  - The objective of this study was to analyze the efficacy of a treatment (MAH) of sunflowerseed (SS) and meal (SM) with a malic acid solution (1 M; 400 mL/kg) and heating (150?C, 2 h) toprotect protein against rumen degradation and to improve the growth of lambs. Two homogeneousgroups of 12 Lacaune lambs each (14.2±0.35 kg body weight) were fed either a concentrate includinguntreated SS and SM or a concentrate with MAH-treated SS and SM. Lambs were fed concentrate andbarley straw ad libitum for 40 days (about 26 kg body weight); feed intake and growth of lambs wererecorded; blood samples were taken on days 0, 20, and the slaughter day for analysis of urea-N andamino acid-N; diet digestibility was determined; and ruminal and cecal samples were collected afterslaughter. Thein vitroincubation of both concentrates with sheep ruminal fluid for 12 h showed thatthe MAH-treatment tended to reduce NH3-N concentrations and increased propionate production.However, there were no differences (p>0.05) between groups in any of the tested variables in thein vivo trial.
