| 摘 要： | 选择106头早期隔离断奶仔猪随机分成2组,A组54头采取14日龄断奶,B组52头采取21日龄断奶。全自由采食的条件下,通过观测,记录采食量、采食次数与采食时间间隔、对不同料型的采食兴趣。结果表明,断奶第二天的采食量明显高于第一天,在断奶第2~5d采食量明显较高;断奶后两周内,两组的平均日采食量相对较低,第三周有所上升,在第四周后采食量明显加大;不同阶段的仔猪白天采食次数均高于夜间,并随着仔猪日龄的增长,夜间与全天采食次数逐渐减少,采食间隔延长;不同日龄的仔猪均喜食稠料,且采食稠料的时间最短。

| Abstract: | 106 weanling piglets are divided into two groups at random,with 54 piglets in group A weanling at the age of 14 days,while 52 in group B at the age of 21 days.Under the condition of eating completely freely,the piglets'appetite, number of times for eating,eating intervals and interest in different types of fodder are observed and recorded.The result shows that: the appetite in the second day apparently surpasses that in the first day after weanling,and there is a distinct increase in the appetite during the 2-5 days;the average daily appetite in the first two weeks for the two groups is comparatively small,with a slight increase in the third week and a distinct increase in the fourth week;the number of times of eating for piglets at all stages in daytime is higher than that at night,the number of times of the piglets'eating at night and in the whole day decreases gradually as the days increasing,while the eating intervals become longer;piglets at all stages are fond of thick fodder and the duration for eating thick fodder is the shortest. |
