Feeding Broiler Litter to Beef Cattle
نویسندگان
چکیده
an annual rate of 7 percent since 1986 with 371 million broilers produced in 1994. Broiler litter (mixture of poultry excreta, bedding material, wasted feed and feathers) is usually removed from the poultry houses on an annual basis. Because of its high nutrient content, poultry litter is usually applied to agricultural land as fertilizer with an economic value of $20 to $30/ton. Broiler litter has a higher value as a feed for beef cattle. Cattle are ruminants and can digest material high in cellulose, hemicellulose and fiber. Byproducts of many grain and food processing industries (i.e. citrus pulp, sugar beet pulp, brewers grain, corn gluten, fish meal, cotton hulls, and rice bran) are fed to cattle. In the 1960s researchers in Virginia brought attention to the economics of feeding broiler litter to beef cattle. Feed quality litter is high in protein and minerals but low in energy relative to grain or high quality forage. If used as a protein and mineral supplement in a feed ration, feed quality broiler litter has a value of about $100/ton; soybean and cottonseed meal are valued at $200/ton. When fed at a 1:1 ratio with corn to 550pound heifers, broiler litter has a value of $106/ton (McCaskey et al., 1994). Following is a discussion of the advantages and disadvantages of feeding broiler litter to beef cattle utilizing information from other states and two surveys on broiler litter feeding in the eastern half of Texas.

Corn Silage in Sustainable and Conventional Systems for Finishing Beef Cattle
19-33 ABSTRACT The objective of the research was to compare finishing beef steers on high corn (Zea mays L.) silage diets in which the corn was produced under conventional and sustainable systems. The conventional corn forage was produced on a given area for 5 yr, using conventional practices, alternating with 5 yr of alfalfa (Medicago sativa L.) The sustainable system corn forage was produced ...
متن کاملEffects of feeding with broiler litter in pellet-form diet on Qizil fattening lambs’ performance, nutrient digestibility, blood metabolites and husbandry economics
The aim of this study was to evaluate the feeding of Qizil fattening lambs with different levels of broiler litter (BL) on their weight gain, dry matter intake (DMI), nutrient digestibility, selected blood metabolites and husbandry economics. During an eight-weeks experimental period, 28 male lambs (an average of 42.21 ± 5.63 kg and ages of 7-8 months) were allocated randomly to one of four die...

Proper application of livestock manure to agricultural land converts waste to fertilizer, but relies on knowing the nutrient content of the manure. Manure samples (111 solid poultry layer, 95 solid poultry broiler litter, 39 swine solid hoop, 72 beef cattle, 85 swine slurry, and 88 swine liquid lagoon) were collected from farms in three states to investigate the feasibility and limitations for ...
