| Abstract | A trial was conducted to determine the effects of increasing levels of water restriction on body weight, feed consumption, feed conversion and mortality of broiler chicks to eight weeks of age. In addition, the effects of water restriction on water:feed ratios, water consumption per pound of body weight and on the percent of toe moisture were observed. A total of 312 one-day-old broiler chicks were placed on regimens of 10, 20, 30, 40 and 50 percent water restriction after the first week based on ad libitum intake of the control chicks for the previous 24 hours. Water and feed were weighed and recorded daily for all treatments during the eight-week trial. The chicks were bulk weighed weekly by sex and brooded on floor pens under infra-red lamps in a forced-draft ventilated house. Results indicated that feed consumption, water consumption, body weight, water:feed ratio and water consumption per pound of body weight were decreased with each increment of water restriction. A significant difference in body weight between males and females was found in all groups throughout the trial. Interactions due to replication, sex x replication and sex x treatment were not present. Water restriction was found to be deleterious to feed conversion with each increment of water restriction. Mortality and percent toe moisture content were not significantly affected by water restriction. Edema and degeneration of the cells lining the tubules of kidneys were the only changes observed in the body tissues of the 50 percent restricted chicks. For all practical purposes the optimum amount of water consumed by the growing chick to eight weeks of age under conditions of this experiment equals 10.61 pounds per bird. |
