Feeding corn milling byproducts to feedlot cattle.
Corn milling byproducts are expected to increase dramatically in supply as the ethanol industry expands. Distillers grains, corn gluten feed, or a combination of both byproducts offer many feeding options when included in feedlot rations. These byproduct feeds may effectively improve cattle performance and operation profitability. When these byproducts are fed in feedlot diets, adjustments to g...
متن کاملSpectral analysis of feeding and lying behavior of cattle kept under different feedlot conditions.
This study used spectral analysis in 2 separate experiments to examine feeding and lying behavior of Bos taurus steers under 2 housing treatments: a feedlot yard stocked at 12.0 m2 per head with a dry, firm pen surface (NDF) and a "high density" (HDF) feedlot yard stocked at 6.0 m2 per head with a wet and muddy feedlot pen surface. The study conducted 1 experiment in Autumn, another in Spring. ...
متن کاملWheat distillers grains in feedlot cattle diets: feeding behavior, growth performance, carcass characteristics, and blood metabolites.
A study was conducted to evaluate feed intake, ADG, carcass quality, eating behavior, and blood metabolites in feedlot beef steers fed diets that varied in proportion of wheat dried distillers grains with solubles (DDGS) replacing barley grain or barley silage. Two hundred crossbred steers (BW = 489 ± 30 kg) were blocked by BW and randomly allotted to 20 pens (5 pens per treatment). Steers were...
متن کاملFat Quality and Feeding Value of Fat for Feedlot Cattle
While much attention has been directed at understanding factors influencing the NE value of supplemental fat (Zinn, 1994), alterations in NE do not necessarily form the basis for constraints on supplementation. Indeed, greater concern is often directed at potential detrimental effects of supplemental fat on diet acceptability and feed intake (Brethour et al., 1957; BuchananSmith et al., 1974; C...
متن کاملFeeding value of cottonseed meal for feedlot cattle.
One hundred twenty crossbred steers (294 kg, initially) were used in a 141-d finishing trial. Four concentrations (8, 16, 24, and 32% of diet DM) of cottonseed meal (CSM, prepressed solvent-extracted) replaced steam-flaked corn in a corn-based finishing diet. Increasing level of CSM decreased ADG (linear component, P < .10), feed efficiency (linear component, P < .01), and dietary NE (linear co...
