OBJECTIVE To investigate whether supplementation of carbohydrate together with peptide glutamine would increase exercise tolerance in soccer players. METHODS Nine male soccer players (mean age: 18.4 +/- 1.1 years; body mass: 69.2 +/- 4.6 kg; height: 175.5 +/- 7.3 cm; and maximum oxygen consumption of 57.7 +/- 4.8 ml x kg(-1) x min(-1)) were evaluated. All of them underwent a cardiopulmonary e...

This study was conducted to investigate the effects of different levels of peptide supplementation on rumen fermentation pattern, digestibility and microbial protein synthesis. Three rumen-cannulated Holstein dairy cows were used in a 3 × 3 Latin square experiment within 21 days period. The ruminal infusion of sodium caseinate (CN) was 0 (control), 50 and 100 g/d. Dry matter intake, milk yield ...

As dietary supplementation with β-glucans can stimulate the innate immune response in the porcine gastrointestinal system (GIT), the aim of this study was to determine if the effects of β-glucan supplementation extend beyond the GIT to systemic levels. Hence, the effects of dietary supplementation of β-glucans derived from Laminara digitata, Laminara hyperborea, and Sacharomyces cerevisiae on c...

Ten Holstein steers (141 kg) were used in two 5 X 5 Latin-square experiments conducted simultaneously to determine the effects of offering different levels and types of feeds with endo: phyte-infected rescue given ad libitum. In Exp. 1, steers wer e given ad libitum access to infected fescue hay in the afternoon; in the morning fescue was given ad lihitum (basal) or bermudagrass or clover hays ...

SCHISANDRAE FRUCTUS (SF), WHICH POSSESSES FIVE TASTES sweet (fruit skin), sour (pulp), bitter/pungent (seed core), and saltiness (all parts), can produce a wide spectrum of biological activities in the body. Here, we investigated the effects of the ethanolic extract of SF pulp, seed, or their combination (namely, EtSF-P, EtSF-S, or EtSF-P/S, resp.; collectively called EtSF) on the metabolism of...

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...

This experiment studied the effects of whole yeast cell product supplementation on broiler production parameters, fecal coccidial oocyst counts, and local and systemic immune parameters following an experimental coccidial infection. Birds were fed 0, 0.1, or 0.2% whole yeast cell product (CitriStim). At 21 d of age, birds were challenged with live coccidial oocysts. Supplementation with whole y...

The objective of this work was to evaluate the effects of supplementation with nitrogen and starch on the nutritional performance of grazing cattle during the rainy season. Five rumen cannulated Nellore steers, averaging 211 kg of body weight (BW), were used. Animals grazed on five signal grass paddocks. Five treatments were evaluated: control (forage only), ruminal supplementation with nitroge...
