Increased efficiency of nutrient utilization can potentially be gained with increased starch digestion in the small intestine ruminants. However, ruminants have quantitative limits extent disappearance intestine. The objective is to explore nutritional and physiological constraints that contribute limitations carbohydrate assimilation ruminant Altered digesta composition passage rate intestine,...

Two experiments were conducted to determine the NE content of dry extruded-expelled soybean (DESBM) and the effect of a multienzyme carbohydrase (MC) mixture on the NE content of DESBM and to determine the effect of diet design on NE values in growing pigs using indirect calorimetry (IC). In Exp. 1, 24 barrows (19.6 ± 0.51 kg BW) were allotted in a completely randomized design to 4 dietary trea...

The aim of the present experiment was to determine the influence of either probiotic or antibiotic inclusion in the diets of pigs from birth on the development of enzyme activity in the small intestine. Pigs were fed on creep feed and grower diets containing either a probiotic, an antibiotic or no added growth promoter. At 7, 17, 42 and 80 d of age pigs from each treatment group were sampled to...

The cholera toxin (CT)-binding activity of purified κ-casein macropeptide (CMP) from bovine κ-casein was detected. In addition, a statistical model was developed to optimize the production of CMP. CMP was prepared by chymosin hydrolysis of κ-casein and a subsequent 3% trichloroacetic acid treatment. CMP was further fractionated in an ion-exchange column by FPLC. CT binding activity was eluted a...

Several bacteria from the islands of Puerto Rico, Vieques and Trinidad were isolated for their carbohydrate degrading activities. These terrestrial and marine bacterium were collected from pineapple agricultural lands, tropical rain forests, coastlands and mangrove swamps. Organisms were screened for activity using chromogenic substrates (AZCL Megazyme International Ltd., Ireland). The media co...
