A floor pen study was conducted to determine the effects of feed restriction with subsequent gorging and water restriction on 5- to 10-wk-old toms fed graded levels of monensin. Eight treatments were factorially arranged with four levels of dietary monensin (0, 60, 100, and 140 ppm) and two feeding-watering regimens (ad libitum and restricted). Restricted birds had access to feed daily from 0800 to 1200 h and had no access to water during this period. The ad libitum birds had full access to feed and water. Feed restriction decreased (P .10) on feed:gain ratio. The mortality rate of restricted birds was 82% less (P .10) influence on the incidence of mortality. No treatment-related abnormalities were observed during either interim or terminal necropsies. Neither clinical signs of ionophore toxicity nor pathologic findings attributed to monensin treatment were observed during the study. Under the conditions of this experiment, the gorging of monensin treated (60 to 140 ppm) feed without access to water will not adversely affect the health status, or increase the mortality rate, of 5- to 10-wk-old male turkeys. |
