The effects on N use and N volatilization from slurry were investigated in 24 early-lactation Brown Swiss cows (32 kg/d milk) fed four diets with 128, 124, 147 and 175 g/kg DM of crude protein (CP). All diets were supplemented with 0.75 g/kg of rumen-protected Met except for one of the low-protein rations (128 g/kg of CP). The unsupplemented low-protein ration was calculated to be deficient in ...

Distillers grains are co-products produced from the fermentation of grains for alcohol. Traditionally, alcohol was produced mainly for the beverage liquor industry, but in the last 20 years its use as an alternative fuel has increased significantly. This increased demand has led to the development of several ethanol production plants in Minnesota and the surrounding area. In 1996, it is estimat...

Phytate in poultry rations containing rice bran (RB) critically reduce poultry performance while increasing N and P excretion. The objective of this study was to determine whether the anti-nutritive problems associated with higher inclusions of rice bran in poultry rations (up to 40%) could be mitigated with mega doses of phytase. Twenty days old male broiler chicks (n=180) in 60 floor pens wer...

Considerable interest was manifested in the substitution of blackstrap molasses for a part, or all, of the grain in livestock rations during the drought years of 1934 and 1936. Ferrin ^ used molasses with corn and oats in fattening hogs and found that oats and molasses had a comparatively high value as compared with corn and molasses. Thompson and HilHer ^ experienced similar results in feeding...

A study was designed to collect a database of Iowa feedlot rations for determination of effective neutral detergent fiber (NDF) in complete diets from fiber analysis and particle size determination of individual feed ingredients and compare this with particle size determination of mixed wet rations. Seventy-one beef finishing total mixed rations were collected by ISU Extension Beef Field Specia...

Palm Kernel Oil Residue (PKOR) is a waste product obtained after extracting oil from palm kernel by cottage industries. The residue is dumped at processing sites and the stench that emanates from the oxidizing product, causes nuisance to processors and nearby residents. Animal scientists are advocating the use of the fresh product as energy resource in broiler rations. This study was therefore ...

Feed production is a significant source of greenhouse gas (GHG) emissions from dairy production and demands large arable and pasture acreage. This study analysed how regional conditions influence GHG emissions of dairy feed rations in a life cycle perspective, that is the carbon footprint (CF) and the land area required. Factors assessed included regional climate variations, grass/clover silage...

The following study was undertaken in the winter of 1944-5, three months after the liberation of Belgium, in order to determine if permanent illeffects of the occupation were manifest in children reared during the war; to review the measures that had been taken to protect children against the severe deprivations from which the country as a whole had suffered; and to assess how far these measure...

Corn-finished cattle are the backbone of US beef production system. Traditionally fed a total-mixed ration (TMR) where all feed ingredients mixed together, delivered, and daily to cattle. Previous research evaluated complete self-fed finishing rations diet is placed into self-feeder. With advancements in technology varieties corn, purpose this study was determine differences gains, efficiency, ...
