摘　　要：随机选择1～4胎次健康崂山奶山羊40只,按胎次分为4组,每胎各10只作为一组。统计各胎次泌乳天数、产奶量、各泌乳月产奶量以及不同季节的产奶量。结果表明：舍饲条件下崂山奶山羊的平均泌乳天数为（262.3±12.9）d,平均泌乳量为（401.8±107.3）kg;第一胎平均泌乳天数最短,第三胎最长（P〈0.05）;平均泌乳量以第三胎最高,第一胎最低（P〈0.05）。产奶量随月份变化规律为每年4、5、6、7月份产奶量比较高,到8月份迅速下降。The lactation pattern of 1~4 fetal times in 40 Laoshan milk goats were randomly allotted to 4 groups according to fetal times. The lactation days of fetal times, the total of milk yields, milk yields of different lactation month and seasons were measured. The results indicated, the average lactation days and milk yields were（262.3± 12.9）, （401.8± 107.3）kg, respectively; the average lactation days of first-time was the shortest, the third-fetal the longest（ P 〈0.05） ; The average milk yields of third-fetal was the highest, the first-time the lowest（ P 〈0.05）. The milk yields were relatively high in April,May,June,Ju- ly with months and decreased rapidly in August.
