Effect of Feeding Wet Distillers Grains with Solubles to Beef Cattle on Air and Manure Quality
Air quality is becoming a pressing issue for beef feedlot producers. Feeding practices influence the excretion of starch, fiber, nitrogen (N), and sulfur (S) in manure, thereby affecting nutrient content and the production of ammonia (NH3) and odorous compounds. Wet distillers grains with solubles (WDGS) are a common and economical ingredient in feedlot diets. WDGS are high in protein, fiber, p...
متن کاملApproaches to the Level and Quality of Forage in Feedlot Diets for Lambs
Diets with low forage concentration may depress feed intake and average daily gain, while diets with high forage concentration may limit feed intake due to rumen filling. Adequate forage level may range from 7% to 14% in ration for feedlot lambs, depending on forage source and ingredient composition. Small amounts of good quality forage may improve growth performance of sheep in the first stage...
متن کاملWeed seed viability in composted beef cattle feedlot manure.
Manure composting has gained increased acceptance by the beef cattle (Bos taurus) feedlot industry in southern Alberta, Canada. Unlike fresh manure, compost is often promoted as being "weed-free." Studies were conducted with five weed species in 1997 and thirteen in 1999 to examine the effect of feedlot manure composting on weed seed viability. Weed seeds were buried in open-air compost windrow...
متن کاملImplementing NIR grain quality testing for the feedlot industry: what are the options
A major objective of the "Premium Grains for Livestock Program" is to develop rapid tests, suitable for the site of grain collection and/or use, to measure the nutritional value of grains so that they can be priced in accordance with their suitability as an animal feed. The feedlot industry, as a major user of grain, is well aware of the relationship between the quality of a feedlot ration and ...
متن کاملCattle feedlot soil moisture and manure content: II. Impact on Escherichia coli O157.
The moisture and manure contents of soils at cattle feedlot surfaces vary spatiotemporally and likely are important factors in the persistence of Escherichia coli O157 in these soils. The impacts of water content (0.11-1.50 g H2O g(-1) dry feedlot surface material [FSM]) and manure level (5, 25, and 75% dry manure in dry FSM) on E. coli O157:H7 in feedlot soils were evaluated. Generally, E. col...
