摘要
为了确定断奶应激对仔猪脂类营养代谢的影响,随机选取体重相近的12头断奶仔猪,分别于仔猪断奶时,断奶后第7天、第14天采取血液进行血清脂类代谢指标测定。结果显示,被检仔猪血清CHO、TG活性在断奶后显著(P<0.05)或极显著升高(P<0.01)。血清HDL、LDL在整个试验期间虽有变化,但均无统计学意义(P>0.05)。表明断奶后第14天时,仔猪对脂类物质吸收增强,脂肪沉积增多,该时期可在饲料中适当添加脂类营养物质,这将有利于调节机体代谢和营养调控。
In order to understand the effect of weanling stress on serum lipid metabolism of piglets, 12 weaned piglets with similar body weight were randomly selected, and serum lipid metabolism indexes of their blood were determined when piglets were weaned, 7 days and 14 days after weaning. Result showed that CHO and TG activities of piglet serum were significantly or very significantly increased, but HDL and LDL activities of serum had no significant change. It is suggested that after piglets were weaned for 14 days, they strengthened to absorb lipid materials, and fat deposition increased, so serum nutrients should be properly added into feed during this stage, and it is helpful to adjust body′s metabolism and nutrition regulation.
