REPLACING CORN WITH SUN-DRIED MANURE OF LAYING PULLET, MATURE PIG, SHEEP, AND COW

Sun-dried (30-35.degree. C) manure of adult fowl, pig, cow or sheep was used to replace 5, 10, 15 and 20% of the maize in corn-peanut base diets for started broiler and pullet replacement chicks and for laying pullets. The manure of the fowl followed by that of the cow were superior to that of pig and of sheep in replacing up to 15% of maize (7.5% of the whole diet) for the different categories of birds used in the experiment. The beneficial effects of the poultry and cow manure were manifested most prominently on growth rate of the chicks and on egg production of the layers which were either comparable with or higher than those of the control. The mineral contents of the manure of the fowl and pig were beneficial in maintaining egg size and shell thickness. These types of manure tended to reduce the intensity of egg yolk color.
