摘  要：
在断奶仔猪日粮中添加三甲胺盐酸盐,探讨氯化胆碱中三甲胺超标对断奶仔猪采食量的影响。试验分为两组,对照日粮和试验日粮的氯化胆碱中三甲胺含量分别为220 mg/kg和22 g/kg,同时进行组内比较和组间比较2个试验。组间比较试验采用断奶后5～9 d的杜×(大.长)三元杂交仔猪90头,随机分为对照组及试验组,每组5个重复,每重复9头猪,每栏一个料槽,饲喂对照日粮或试验日粮,试验期8 d。试验结果表明,试验组平均日采食量明显低于对照组(291 g/头vs 382 g/头),其中第0～3天的日采食量差异显著(213 g/头vs 313 g/头,P<0.05)。组内比较试验采用断奶后4～13 d的杜×(大.长)三元杂交仔猪24头,随机分为6组,每组4头猪,每栏设两个料槽,同时饲喂对照日粮和试验日粮,试验期10 d。试验结果表明,仔猪对高三甲胺日粮的采食量明显低于对照日粮,在试验第5～10天和整个试验期日采食量均存在显著差异(202 g/头vs 305 g/头;179 g/头vs 287 g/头,P<0.05)。说明氯化胆碱中三甲胺严重超标对仔猪的采食量会产生不良影响。

摘  要：
Two animal trials were conducted to verify whether the high trimethylamine residuals in choline chloride would affect the daily feed intake in weaned piglets.In trail 1,90 Duroc×(Landrace·Large white) crossbred weaned piglets at average weighted 7.3 kg were divided into 10 groups randomly.The trial diet had the same ingredient composition with control diet except a 22 g/kg trimethylamine hydrochloride addition.Five groups of animals were randomly assigned to test or control diets.After 8 days,it was demonstrated that the average daily feed intake in test groups was steadily less than that of control groups(291 g/d vs 382 g/d),especially at the beginning stage of trial,0~3 day(213 g/p/d vs 313 g/p/d,P<0.05).Twenty-four piglets,as above,were divided into 6 groups in the second trial.Both the trial and control diets were given simultaneously to each group.After 10 days,it was demonstrated that the intake of test feed was less than control in 5~10 day and whole tested days(202 g/d vs 305 g/d;179 g/d vs 287 g/d,P<0.05).It concluded that the high residual of trimethylamine in choline hydrochloride products had an adverse effect on the feed intake in weaned piglets.
