The Effect of Feed Restriction on Growth Performance on Pigs.

Abstract

Three litters of six pigs were allocated to one of six treatments. These were ad libitum grower ration and 90 per cent, 75 per cent, 60 per cent, 40 per cent and 25 per cent of the consumption of the ad libitum group. The experiment was continued until each group reached a mean weight of 200 po1mds. Growth rate was most rapid in the 90 per cent group treatment and declined according to restriction. The ad libitum group had the worst food conversion ratio. The time taken to reach 200 pounds for the groups were 170, 161, 187, 213, 272 and 411 days respectively.
