Performance of Spanish and Boer × Spanish doelings consuming diets with different levels of broiler litter

Effects of ammoniation of wheat straw and supplementation with soybean meal or broiler litter on feed intake and digestion in yearling Spanish goat wethers

Since the 1950s, recycled poultry bedding has been used as an economical feedstuff for beef cattle. It has been extensively studied at several experiment stations around the world with regard to its safety and nutritional aspects. It will continue to be closely scrutinized as the public increases its awareness of agricultural issues. As this study was being prepared, the news media was "spotlighting" bovine spongiform encephalopathy. Currently, in the United States there is a ban on incorporation of mammalian-derived protein feeds into ruminant diets. This has led to a requirement of beef cattle producers signing affidavits indicating that they had met this obligation. Some poultry companies use ruminant meat and bone meal in broiler diets when least-cost formulation indicates that it is economically desirable. This then poses the question of whether feeding RPB to beef cattle should be permitted if the birds had been fed ruminant meat and bone meal. It also raises the question of whether cattle grazing pastures fertilized with RPB are exposed to ruminant meat and bone meal. Because of the importance of pasture fertilization as a waste disposal solution for the poultry industry, it seems that the issue will be quickly resolved by omitting the ruminant meat and bone meal from poultry diets should concerns increase. Use of RPB, like many byproduct feeds, requires a higher level of management expertise than traditional feeds. Despite the potential problems discussed in this study, an informed beef cattle producer can gain a financially competitive edge by using RPB. A simple processing method, deep-stacking under polyethylene sheeting, can produce a safe product that will provide a complete diet when blended with an energy source and supplemented with some long-stem fiber. The diets can be used for both brood cows and stocker calves for extended periods of time, and the practice of feeding RPB is safe for both cattle and consumers [45]. Economic parameters will influence the future use of RPB; however, the general public's perception and acceptance will ultimately determine its long-term use.

Effects of level of broiler litter in diets containing wheat straw on performance of Alpine doelings

The aim of this experiment was to determine the site and extent of digestion of nutrients in sheep fed broiler litter alone (100% litter treatment), broiler litter plus 7.5% sugarcane molasses (92.5% litter treatment) and broiler litter plus 15% molasses (85% litter treatment). Voluntary intake was increased by molasses, apparently due to an increased rate of passage of digesta through the digestive tract. This resulted in a shift in the site of disappearance of organic matter (OM) from the rumen towards the lower digestive tract. For the 100 and 92.5% litter treatments, 0.37 and 0.46 of dietary OM disappeared in the rumen respectively, compared to 0.21 for the 85% litter treatment, while 0.16, 0.08 and 0.35 of dietary OM disappeared in the small intestine for the 100, 92.5 and 85% litter diets respectively. In the case of the 85% litter treatment, 0.26 of dietary nitrogen (N) disappeared in the rumen and 0.45 in the small intestine, compared to 0.55 and 0.62 in the rumen and 0.18 and 0.11 in the small intestine for the 100 and 92.5% litter diets respectively. There were no differences between treatments for total tract apparent digestibility of N (0.73) and OM (0.65-0.73), rumen degradability of N (71-87%) or concentration of ammonia-N in rumen fluid (53 mg/100 ml). It was concluded that the addition of molasses might be advantageous when the intake of litter is restricted or when voluntary intake of litter is unacceptably low.
