This experiment was designed to determine the influence of processed or raw six feed ingredients
and environment temperature on ruminal degradability and amino acid profile in twelve male sheep. A total
of twelve canulated male sheep (average BW 60 kg) were used in this 9 days trial. The experiment was
arranged in a 3x2x2 factorial design, in which sheep (3 replicates), diet type (processed or raw), and
environment temperature (20 and 30ºC) were the main effects to investigate. The animals were given restrict
access to a Totally Mixed Ration (TMR) and infused daily with: Raw corn meal (T1), Processed corn meal (T2),
Raw soybean meal (T3), Processed soybean meal (T4), Raw distillers dried grains with solubles (T5), and
Processed distillers dried grains with solubles (T6). Environmental temperatures (20 and 30ºC) did not affect
rumen temperature but had significant effect on ruminal pH and NH4+, concentrations (p<0.05). There was
significant effect (p<0.001) of dietary treatment on ruminal fermentation parameters pH, NH4+, NO3-,
individual volatile fatty acid concentrations and their ratios (C2/C3; C2/C3+C4). Amino acid (AA) profile after
6 and 24 h exposure varied between temperature levels and ingredients. Except for Ser, Val, and Pro (p<0.05,
p<0.05, and p<0.01) respectively, none of the AA measured showed any significant difference after 24 h of
ruminal incubation. In general, all protein supplements, except soybean meal, were high in rumen undegradable
protein and had the potential to provide good quality AA to complement microbial AA for production.
Key words: Amino acid, environment temperature, feed supplements, ruminal degradation, sheep, ,
