| 摘 要： | 采用不同甜菜碱添加量(0，1000，1250，1500，1750mg/kg)的同种饲粮，分别饲喂5组(150头)“杜长大”肥育猪(63kg)40d,对背最长肌、肝脏、血液氨基酸组成进行分析。结果表明:不同剂量甜菜碱对肌肉和肝脏的氨基酸组成无显著影响,但对血清中游离氨基酸的影响较为明显,其中游离丝氨酸和缬氨酸含量升高较为显著,分别提高了14.28％(P<0.05)和31.75％(P<0.05).

Effect of betaine onmuscle,liver and serum amino acid composition in finishing swine |
| |
| Abstract: | One hundred fifty finishing pigs (Duroc× Landrace×yorkshire) wereallotted to five groups which received the same basal diet, supplemented with 0, 1 000, 1 250, 1 500, 1 750 mg/kg betaine. On finishing40 days feeding experiment, 60 pigs were slaughted, the longissimus dorsi, liver and serum samples were collected and amino acid composition were analysed. The results indicated that different level betaine hereof did not affect the amino acid composition of longissimus dorsi and liver, but some of the free amino acid contents were improved in serum especially the serine and valine which were increased by 14.28％ (P<0.05) and 31.75％ (P<0.05), respectively. |
