IT HAS been reported that the domestic fowl can tolerate high levels of cane final molasses during all stages of growth and maturity up to 72 weeks of age. According to Rosenberg (1955), cane final molasses was fed to day-old chicks for 6 weeks at concentrations up to 34.5 percent of total ration, the highest level tested, and optimum results were obtained on levels ranging from 7.5 to 23.0 percent. In other studies (Rosenberg, 1954; Rosenberg and Palafox, 1956), mature chickens also exhibited marked tolerance to comparatively high concentrations of molasses. In the three trials of the latter study, hens reared from day-old and maintained on 28.5 percent molasses produced, from 24 to 72 weeks of age, more and larger eggs, fewer meat- and blood-spotted eggs, suffered approximately the same mortality, and required 3.2 cents less feed per dozen eggs than did their controls. It was observed in these studies … |
