ABSTRACT
The objective of the study was to investigate feed intake, blood biochemistry, liver function, and ruminal fermentation in sheep fed heat-treated jatropha meal. The experiment was performed twice (experiment I and II). The subjects were 6 wethers. They were divided into two treatments (rapeseed diet and jatropha diet) randomly and were tested by using a cross over method. Rapeseed meal and jatropha meal were relaced to the feed as a concentrate with proportion of 5% in experiment I and 10% in experiment II. The ingestion rate of sheep fed the jatropha diet was lower than that of the rapeseed diet. The feed of jatropha diet and rapeseed diet were all ingested in experiment I. However, jatropha meal treatment left a large amount in experiment II. According to the above results, there was no obvious difference of blood characteristics between two treatments in experiment I and II, and no difference of Ruminal pH and total volatile fatty acids concentration between two experimental diets, and the palatability of jatropha meal showed to be bad. However, the blood parameter and rumen fermentation did not show any abnormal value after using jatropha meal of 5% and 10% of concentrate in sheep.
