The Effects of Micronisation on Ruminal Starch Degradation of Corn Grain
نویسندگان
چکیده
This study was conducted to evaluate the effects of infrared irradiation for 60, 90, 120 and 150 seconds on starch degradability and chemical compositions of corn grains. Three ruminally fistulated rams were used to measure in sacco degradation. There was a linear increase in DM of irradiated corn grains (P<0.001). Infrared irradiation decreased potentially degradable fraction and constant degradation rate of starch (P<0.05). Effective ruminal degradability of starch for irradiated corn grain decreased linearly (P<0.001) as irradiation time increased.

Degradation Characteristics of Infrared Processed Barley Grain and Its Feeding Effects on Ruminal pH of Sheep
This study was conducted to investigate the effects of infrared processing of barley for 60, 90, 120 and 150 seconds (s) on protein hydrophobicity, in vitro protein digestibility, degradation characteristics of protein and starch and its feeding effect on ruminal pH of sheep. The surface hydrophobicity of protein increased (P
متن کاملThe Effects of Indigestible Neutral Detergent Fiber (iNDF) of Alfalfa Hay and Corn Silage on Ruminal Degradability of Ration Fiber in Sheep
Two experiments were carried out to evaluate the effects of indigestible neutral detergent fiber (iNDF) of ration for estimation of rumen degradability of fiber in sheep. In experiment 1, to determine feed iNDF, four ruminal fistulated Zel ewes were used. Three grams of alfalfa hay, corn silage, barley grain, wheat bran, ration 1 (including alfalfa hay and concentrate), and ration 2 (including ...
متن کاملEffect of a saponin-based surfactant and aging time on ruminal degradability of flaked corn grain dry matter and starch.
The objectives of this study were to investigate the effect of a saponin-based surfactant, Grain Prep surfactant (GP), and hot flake aging time on starch characteristics and ruminal DM and starch degradability of steam-flaked corn grain. In 2 experiments, the moisture content of incoming corn was automatically adjusted using the Grain Prep Auto Delivery System to 19.8% (Exp. 1) and 18.5% (Exp. ...
متن کاملEffects of extruded corn or grain sorghum on intake, digestibility, weight gain, and carcasses of finishing steers.
We conducted two trials to evaluate the effects of extruding vs dry-rolling either corn or grain sorghum on intake, digestibility, and performance of finishing steers. In Trial 1, 92 crossbred steers (average BW 413 kg) were used in a 2 x 2 factorial design. Diets contained either dry-rolled corn (RC), extruded corn (EC), dry-rolled grain sorghum (RGS), or extruded grain sorghum (EGS). Diets we...
متن کاملInfluence of Processing of Barley Grain on Characteristics of Digestion, Ruminal Fermentation and Digestible Energy of Diet inLactating Cows
A digestion trial using cannulated lactating cows was conducted to evaluate the influence of barley grain processing on characteristics of ruminal fermentation and the site and extent of digestion. The experiment consisted in 4 periods and lasted 84 days. The total mixed rations contained 39.86% of grains and 42.90% of alfalfa hay and the rest of ration was composed mainly by cane molasses, fat...
