Deep-Stacked or Composted Broiler Litter in Growing Cattle Diets1, 2
TL;DR: High dietary levels of stacked or composted litter for growing ruminants with high energy requirements may restrict performance primarily as a result of low digestibility of litter.

TL;DR: Use of RPB, like many byproduct feeds, requires a higher level of management expertise than traditional feeds, but an informed beef cattle producer can gain a financially competitive edge by using RPB.
Abstract: 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.

TL;DR: Results on chemical composition and digestibility of excreta, contents of amino acids, minerals, vitamins and antinutritional ingredients ofexcreta from poultry, pigs and ruminants have been presented and possibilities of chemical treatments to improve the feeding value of excrete are demonstrated.
Abstract: Flachowsky, G. 1997. Animal excreta as feedstuff for ruminants-A review. J. Appl. Anim. Res., 12:1–40. Animal excreta contain several nutrients which can be recycled. Coprophagy has been recognised as a normal physiological phenomenon in rabbits and rodents and is natural in many wild and domestic species. Interesting research in the field of determination of feed value and re feeding of animal excreta has been done during the last 30 years. The paper summarizes results on chemical composition and digestibility of excreta. Apart from proximate composition, contents of amino acids, minerals, vitamins and antinutritional ingredients of excreta from poultry, pigs and ruminants have been presented. Possibilities of chemical treatments to improve the feeding value of excreta are demonstrate. Feeding of excreta from poultry, pigs and cattle to growing cattle is the other main topic of the review. Finally the influence of excreta feeding on quality of animal products is discussed.

TL;DR: Supplementation of a diet containing broiler litter with a corn-wheat mixture compared with corn alone decreased ruminal ammonia N concentration early after feeding but did not change duodenal microbial N flow or efficiency of microbial growth.

TL;DR: In conclusion, separating deep-stacked broiler litter into two particle size fractions did not alter feeding value as assessed by digestible organic matter intake by growing steers.

TL;DR: Catalyzed phenol-hypochlorite and ninhydrin colorimetric procedures were adapted to the Technicon AutoAnalyzer for simultaneous determination of ammonia and total amino acids in ruminal fluid or ruminal in vitro media and indicated high degrees of accuracy and precision for both ammonia and amino acid analyses.
