This experiment was conducted to study the effects of dietary methionine levels on growth performance and fur quality of young New Zealand meat rabbit. Eighty young New Zealand meat rabbits with body weight of (1.050±0.058) kg were randomly divided into 4 groups. Rabbits in the control group were fed the basal diet which contained 0.24% methionine and those in the other groups were fed diets supplemented with 0.20%, 0.40% and 0.60% methionine based on the basal diet. The feeding trial lasted for 60 days. The results showed as follows: average daily gain, feed consumption, hair density and mechanical properties indices of wool were elevated with the increasing of dietary methionine levels, but they tended to be reduced when the level of methionine was more than 0.64% (P>0.05); the feed/gain was decreased firstly and then elevated with the increasing of dietary methionine levels; there were no significant difference among the various groups in skin thickness, skin weight, mechanical and physical properties of skin (P>0.05). These results indicate that methionine could improve the growth performance and fur quality of New Zealand meat rabbit, the better effects were obtained with 0.64% methionine in diet.[Chinese Journal of Animal Nutrition,2011,23(1):73-77]
