Abstract

Eucommia ulmoides leaf was a kind of high quality roughage that has many active nutrients. This experiment was conducted to study the effects of Eucommia ulmoides leaves on nutrient digestion and utilization, growth performance and slaughtering performance of sheep. Thirty healthy lambs (Hu sheep) with the similar age and body weight were randomly divided into three groups with ten lambs per group, which were named control group (normal ration, without Eucommia ulmoides leaves, CTL group), low level of Eucommia ulmoides leaves group (ration with Eucommia ulmoides leaves instead of 10% of roughage, EUL1 group) and high level of Eucommia ulmoides leaves group (ration with Eucommia ulmoides leaves instead of 20% of roughage, EUL2 group) for the feeding experiment and metabolism experiment. The results showed that dietary supplemented with different levels of Eucommia ulmoides leaves had significant effects on final weight, body weight gain, feed intake and daily gain of sheep (P<0.05), also had significant effects on the digestibility and deposition rate of energy and nitrogen (P<0.05), had no significant effects on the digestibility and deposition rate of calcium and phosphorus (P>0.05), had significant effects on the dressing percentage and percentage of carcass net muscle (P<0.05), and had no significant effects on the carcass weight, meat weight, bone weight and meat to bone ratio (P>0.05). In conclusion, Eucommia ulmoides leaves greatly affect the ratio of feeds digestion and utilization as well as growth and slaughtering performance of sheep, the improvement degree is related to the level of Eucommia ulmoides leaves.
