The concentration of gross energy in distillers dried grain with solubles (DDGS) is greater than in corn. However, because of a lower digestibility of energy in DDGS than in corn, there is no difference in the concentration of digestible and metabolizable energy between DDGS and corn. The apparent and standardized ileal digestibility of amino acids in DDGS does vary among sources but, with the ...

Ninety-six crossbred sows and gilts were used to study the effect of yeast culture (Diamond V. Mills, Cedar Rapids, IA) on apparent nutrient digestibilities and reproductive performance from d 60 of gestation through d 21 of lactation. Sows were allotted to treatment groups based on parity and BW. Four dietary treatments were made by substituting 0, .5, 1.0, or 2.0% yeast culture for wheat midd...

External markers for determination of nutrient digestibility have often been evaluated in conventional dry feeds but less often in conventional feeds such as human-type diets used in animal model studies. In the present study, 5 ileal-cannulated pigs were fed 5 types of soft bread-based diets supplemented with Cr(2)O(3) and AIA as digestibility markers for 1 wk in a Latin square design. Ileal c...

Ecological stoichiometry suggests that plant Nitrogen (N)-to-Phosphorus (P) ratios respond to changes in both soil N:P stoichiometry and soil N and P availability. Thus we would expect that soil and plant N:P ratios be significantly related along natural gradients of soil development such as those associated with primary ecological successions. Here we explicitly search for linkages between pla...

OBJECTIVE The objective of the study was to determine the effect of fermented spent coffee ground (FSCG) on nutrient digestibility and nitrogen utilization in sheep. METHODS Fermentation of spent coffee ground (SCG) was conducted using Lactobacillus plantrum. Fermentation was performed at moisture content of 70% and temperature of 39°C with anaerobic air tension for 48 h. Four adult rams (ini...
