| 英文摘要 | Three experiments were conducted to examine the effects of dietary vitamin a supplementation on performance and carcass parameters in limosin x luxi crossbreed finishing steers fed a wheat straw-based diet. sixteen 12-month old (301 +/- 22 kg) steers, 16 12-month old (309 +/- 15 kg) steers and 16 24-month old (411 +/- 20 kg) steers were used in experiment 1 for 6 months feeding period, in experiment 2 for three months feeding period and in experiment 3 for three months feeding period, respectively. sixteen steers of each experiment were randomly divided into the four groups of four animals. treatments consisted of four vitamin a supplementation levels (0, 1100, 2200 and 4400iu/kg dm). the growth rate was affected by dietary vitamin a level in experiment 1 and 2, revealing that the suitable amount of vitamin a supplementation increased the growth rate; excessive vitamin a in the ration decreased the growth rate of 12-month-old finishing steers. the marbling deposition decreased with the increment of vitamin a supplementation level, but possibly associated with vitamin a supplementing duration. furthermore, the suitable dietary vitamin a level probably decreased lipid and pigment oxidation, and increased the tenderness of beef meat. vitamin a supplementation had no significant effect on chemical composition of gluteus medius muscle and longissimus dorsi muscle.
