Abstract
Broiler litter has been a valuable feed stuff for many years,1 and has been successfully utilized in the rations of growing-weaning calves, stockers, cattle, brood cows, and bulls. The total digestible nutrients (TDN) in litter averages 50%, which is comparable to good quality hay (Table 1). The crude protein content usually averages 24%2 to 31%3, with much of this nitrogen in the form of non protein nitrogen (NPN). The NPN in broiler litter is utilized most efficiently when fed to animals with a functional rumen.2 When broiler litter is fed it should have a crude protein content of>18%, with <25% of protein in a bound form. Feed grade litter should have an ash content of <28%, and all litter should be inspected for uniform color and odor. Litter not meeting these specifications should not be fed.2 Where possible, litter should be passed over a magnet or screened in order to remove nails, wire, and other metallic particulate. Broiler litter is very abrasive and corrosive and may accelerate wear and reduce the working life of feed handling equipment more quickly than other commonly used feed stuffs. Moist litter does not flow through auger systems well, while litter <12% moisture is dusty and less palatable to cattle.2
