Protein supplements for feedlot rations compared

Roughage Levels in Feedlot Rations

vitro digestibility tended to be greater with ammoniation. In the second trial, very high levels of ammonia, urea or glucose were added. Levels of insoluble protein were much higher in this trial than the other. This reflects the high variability of corn silage. Recovery of nitrogen added as ammonia averaged 82 percent while all of the nitrogen added as urea was recovered. The amounts of insolu...

The Use of Bakery Wastes in Feedlot Rations for Sheep

Intensively feeding animals can be a costly exercise, and as a result many producers are exploring innovative ways to reduce their input costs. Commercial by-products from the human food industry (eg brewers grain, citrus pulp and apple pulp) have recently become popular in animal production. Bakery waste displays favourable characteristics for animal production, however, limited information is...

Ammonium Chloride and Ammonium Sulfate in Cattle Feedlot Finishing Rations

T WO levels of ammonium chloride or of ammonium sulfate were added to the rations of commercial feeder cattle. The rations were made isonitrogenous, essentially isocaloric and to contain the same level of calcium, phosphorus and salt. Total gains were essentially the same for all lots, varying only 15.6 lb (7.1 kg) over a 112 day feeding period. Feed conversion was increased only on the ration ...

Recent Applications of Liquid Supplements in Dairy Rations

Liquid feed supplements (LFS) have a long history of use in dairy cattle feeding. Initially, LFS were used in lick tanks as a source of non-protein nitrogen (NPN) and energy for dry cows and replacement heifers. More recently, with the increased popularity of feeding total mixed rations (TMR), LFS have been marketed with the following claims: • safe and uniform delivery vehicle for micro-nutrie...
