Abstract

Summary

  • 1.

    The suckling behaviour of eight litters is described. The average duration of initial massage of the udder by the piglets, milk-ejection and final massage per nursing, for six complete lactations, was 60.5 sec., 14.2 sec. and 149.3 sec. respectively.

  • 2.

    An apparent correlation was found between the total time spent on massage at each nursing and total milk yield.

  • 3.

    The effect of the position adopted by the sows at nursing times on udder massage and milk yield is discussed.

  • 4.

    Lactation curves of the sows were of a different shape from those of cows and sheep in that they reached their peak three weeks after parturition, remained at that level for a further three weeks and then fell rapidly.

  • 5.

    Correlation between milk consumption and growth rate up to 19 days of age was 0.98.

  • 6.

    The possible effects of the udder massage and the methods of recording yield are discussed.

乳猪的行为观察
Summary1。描述了8只幼崽的哺乳行为。6次完全泌乳后,每次哺乳仔猪初始按摩乳房、泌乳和末次按摩的平均时间分别为60.5秒、14.2秒和149.3秒。在每次护理中按摩的总时间与总产奶量之间存在明显的相关性。探讨了哺乳期母猪体位对乳房按摩和产奶量的影响。母猪的泌乳曲线与奶牛、绵羊的泌乳曲线形状不同,母猪的泌乳曲线在分娩后3周达到高峰,并在此水平上持续3周,然后迅速下降。19日龄前产奶量与生长率的相关系数为0.98.6。讨论了乳房按摩可能产生的效果和记录产量的方法。
