| 摘 要： | 本试验日粮研究低蛋白日粮对点瘦肉型猪生长性能和肉品质的影响,结果表明:日粮赖氨酸含量≥0.9%时,降低蛋白2个百分点,不影响猪的生长性能、屠宰性能和肉品质;而当日粮赖氨酸含量<0.9%时,日粮蛋白含量降低,则显著降低猪的生长性能和屠宰性能,对肉品质无显著影响,但肉色评分有所降低。

| Abstract: | The experiment studied the affectlon of low-protein diets on growth and carcass characteristics of lean-pigs.The results indicated that:when content of diet Lys was more than 0.9%,reducing content of diet protein by 2% didn't affect the growth performance and carcass characteristics of pigs;but when content of diet Lys was less than 0.9%,decreasing content of diet protein remarkably reduced growth performance and carcass characteristics,had no effect on meat quality,but the colour grade decreased. |

| Keywords: | low-protein diet swine growth performance meat quality |
