We evaluated the influence of the main cereal of the diet and the degree of heat processing of rice on apparent ileal and total tract digestibility of nutrients and ileum morphology of pigs at 37 d of age. Control pigs were fed a complex diet that contained 500 g/kg cooked and flaked maize with a degree of starch gelatinisation (SG) of 840 g/kg. Experimental groups received the same complex die...

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...

Six ruminally cannulated steers were used to evaluate the influence of dietary concentrate level on digestion of fiber, rumen pH and fill, and liquid and particulate passage rates. Total tract digestibility of potentially digestible fiber, but not total fiber, was decreased with each increase in concentrate level. Digestion coefficients suggest that potentially digestible fiber is a more approp...

Feed ingredients of plant origin are commonly used in swine diets. However, the major components of plant cell walls, non-starch polysaccharides (NSPs), reduce nutrient digestibility. To improve the efficiency of feed utilization, exogenous enzyme products that degrade NSPs have been widely used in commercial animal feeds. Nonetheless, the effects of exogenous enzyme addition to swine diets on ...

The yeast cell wall (YCW) preparation, Safmannan, was evaluated as a dietary supplement for adult dogs. Using a 5 x 5 Latin square design with 14-d periods, adult dogs cannulated in the terminal ileum were supplemented with 0, 0.05, 0.25, 0.45, or 0.65% YCW based on daily food allowance. Apparent ileal nutrient digestibility responded cubically (P = 0.07 to 0.10) to YCW supplementation. Ileal n...

A trial was conducted to evaluate the dose response of a novel microbial 6-phytase expressed in Aspergillus oryzae (Ronozyme HiPhos; DSM Nutritional Products, Basel, Switzerland) in pigs. Forty-eight individually housed pigs (Landrace × Pietrain; 52 kg BW; 24 males and 24 females) were distributed among 6 experimental treatments consisting of a low-P diet (3.5 g P/kg; 1.1 g digestible P/kg), wh...

Most of amino acid (AA) digestibility values for feed ingredients are obtained using pigs cannulated in the distal ileum. The ileal-cannulated pig model uses pigs older than six weeks due to difficulties related to implanting the T-cannula in distal ileum of younger pigs and complications during the post-surgical recovery. However, to properly formulate the diet of weaned pigs, the nutritive va...

Hetero-yellow (Hu red (RED) and brown (BR, high tannin) sorghums were fed dry-rolled or reconstituted (RED and BR only) to evaluate the effect of variety and reconstitution on the site and extent of starch and protein digestion in steers fitted with ruminal, duodenal and ileal cannulae. Processed grains were incorporated into 88% sorghum (DM basis) diets fed at 2% of body weight in a 5 • 5 Lati...

Male growing pigs were fed a diet containing 250 g/kg of native corn starch (CS; 26% amylose, 74% amylopectin) or 250 g/kg of raw potato starch (RPS), as examples of digestible starch and resistant starch (Type II), respectively. Whole-tract digestibilities of organic matter, crude protein and starch were greater in pigs fed CS than in those fed RPS through at least d 23 of the study. However, ...

The objective of this study was to examine the effect of different forage and supplement combinations on forage and supplement intake and ruminal parameters in steers. Six ruminally fistulated steers were assigned to 1 of 4 treatments during 4 different data collection periods. Treatments were 1) Hay +wet brewers grains (WBG); 2) Hay +dried distillers grains (DDG); 3) round bale silage (RBS) + ...
