title: The use of feed restriction for mortality control of chickens in broiler farms.
abstract: Feed restriction was attempted for the control of mortality at broiler farms. Respiratory signs were observed in both restricted-feed flocks and fully fed flocks, but they were less severe in the restricted-feed flocks. The death rate in the fully fed flocks began to rise at the age of 4 wk but did not do so in the restricted-feed flocks. Mortality in the restricted-feed flocks was significantly lower than in the fully fed flocks aged from 3 to 7 wk. The economic performance with restriction feeding was better than that with full feeding as a result of improvements in viability and feed conversion rates. Feed restriction appeared to be beneficial in decreasing the death losses.
