Compensatory growth after feed restriction during the rearing period in pigs

“…In addition to retarded weight gain there was also a tendency to reduced feed conversion efficiency during the restriction in our study, but the difference was insignificant (p=0.06). This is in agreement with the studies of Gädeken et al (1983) andKaufmann et al (1989) where feed restriction during weaning has caused retarded weight gain and reduced feed conversion efficiency compared to ad libitum feeding. However, the feed restriction during the growing period has had no effect on the feed conversion efficiency (Prince et al 1983, Campbell etal.…”

“…The severity of the feed restriction was 30 % in the present experiment compared to previous studies where the restriction has varied from 15 % (Prince et al 1983, Donker et al 1983 to 45 % (Gädeken et al 1983, Campbell et al 1983. In contrast to the studies, Mersmann et al (1987) and Pond and Mersmann 1990) induced feed restriction which led to actual weight loss of the animals.…”

“…1986 After feed restriction, the compensatory growth effect increased the daily gain and improved the feed conversion efficiency in our study. The previous studies also confirm this effect (Gädeken et al 1983, Prince et al 1983, Campbell et al 1983, Donker et al 1986, Mersmann et al 1987, Kaufmann et al 1989. In contrast to the above studies Pond and Mersmann (1990) could not find any compensatory effect probably because of the severity of the feed restriction which led to a 20 % weight loss during the restriction period.…”

“…In the present study, the compensatory growth was studied after feed restriction during the postweaning period (17-25 kg live-weight) before the beginning of the fullsib test period, because it was assumed to be close to the practice in Finland. In previous reports the period of feed restriction occurred during weaning (Gädeken et al 1983, Kaufmann et al 1989, growing (Prince et al 1983, Campbell et al 1983,Donker et al 1986 or early finishing (Mersmann et al 1987). The compensatory growth has been studied both after restriction in nutrient density of the diet Mersman 1990, Patterson 1985) and after restriction in feed allowance (Prince et al 1983, Kaufmann et al 1989).…”

“…Especially in ruminants the compensatory growth effect is well established. Many reports have shown also that the weight gain of growing pigs increases during ad libitum feeding following a period of restricted feeding (Owen et al 1971, Kirchgessner et al 1979, Gädeken et al 1983, but some studies have not found any compensatory effect (Pond and Mersmann 1990).…”
