THE daily mthionine + cystine (MC) requirement of cobb-broiler chicken was estimated in three con­secutive experiments. In experiment 1, groups 30 day-old birds were fed one eight diets. The diets contained bet­ween 0.52% and 1.08% MC 0.08% stepwise in­crements. Liveweight gain peaked at 0.84% 0.76% levels during 1-21 days (period 1) 21-42 2) growth phases, respectively. intake/bird/d these 0.2...

A total of 144 weaned crossed pigs were used in a 42-d trial to explore the effects of different concentrations/combinations of benzoic acid and thymol on growth performance and gut characteristics in weaned pigs. Pigs were randomly allotted to 4 dietary treatments: i) control (C), basal diet, ii) C+1,000 mg/kg benzoic acid+100 mg/kg thymol (BT1), iii) C+1,000 mg/kg benzoic acid+200 mg/kg thymo...

introduction the compounds known as β-adrenergic agonists (β-aa) are organic molecules that have the ability to bind to β-adrenergic receptors (β-ar) and start biochemical reactions that will result in increase of accretion of skeletal muscle and reduction in accretion of fat. the anabolic responses to β-aa are temporary, with a peak time occurring during the first 14 days, after which there is...

The objective of this study was to evaluate four different feeding strategies using an immunomodulatory feed additive for newly weaned Nellore cattle, before and after road transport, on their physiological parameters performances during the growing phase pastures. In total, eighty-four young bulls (initial BW = 174 ± 11 kg; 7 1 months age) were blocked by initial body weights 42 days transport...

This study evaluated the effects of artichoke leaf powder on growth performance and physicochemical properties of Japanese quailfrozen meat after 3 monthstorage. A total of 240 Japanese quail chicks (1 d old) were raised over a 42-d experimental period. The experiment was performed as a completely randomized design with 4 replicates of 15 quails in each, using a 4 × 2 factorial arrangement with...

The effect of adaptation time on the concentration and pattern of short-chain fatty acids (SCFA) formed in the hindgut of rats given resistant starch (RS) in the form of raw potato starch (RPS) or high-amylose maize starch (HAS) was evaluated. Each starchy material was tested in diets containing 100 g indigestible carbohydrates/kg DM, and fed for 13, 28 and 42 d. At the end of each period, the ...
