PROPER disposal of hatchery refuse, consisting of infertile eggs, dead embryos, shells of hatched eggs and unsalable chicks, continues to be a concern in good hatchery management. The conversion of this material into a feedstuff suitable for poultry not only would solve the disposal problem for the hatcheries but would also make available a new animal protein source for the feed industry.Experimental investigations of the nutritive value of hatchery by-product for poultry have been few. Kempster (1945) fed dehydrated incubator refuse to chicks at levels of 3 and 6% of the total diet as protein replacements of soybean oil meal or meat scrap and observed that growth was not significantly affected to 8 weeks of age. Feed efficiency was slightly inferior with the refuse-containing diets probably because of the high ash content (57%) of the dried refuse. Hammond et al. (1944) fed only the dried contents of eggs incubated…
