The Effect of Two Different Rations and Two Management Practices on Certain Nutrients in Poultry Meat

THE purpose of this study was to compare the nutritive value of uncooked, meat and livers from 9-week-old broilers which had been fed a practical and a semi-synthetic ration while they were being maintained on wire screens or on a floor with built-up litter. Twenty broilers were fed a semi-synthetic ration while housed on wire screens, 15 were fed a practical ration while housed on wire screens and 15 were fed the practical ration but housed on built-up litter. Methods of handling, the composition of the diets, physical characteristics of the carcasses and organoleptic data were presented earlier (Kahlenberg et al., 1961). The left halves of the carcasses had been used for palatability studies; the right halves were used for nutritive evaluation. The right halves of six carcasses were removed from the freezer, at random, to represent each of the three groups of birds. They were thawed…
