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.
