Wheat gliadin was deamidated by using a cation-exchange resin in the presence or absence of added cysteine, with the change in digestibility being measured. The allergenicity of the gliadin was evaluated by using sera from patients RAST-positive to wheat. Gliadin-specific IgE was measured after the gliadin had been orally administered to rats. The addition of cysteine before the treatment with ...

In this review, the terminology that is used to describe the bioavailability and ileal digestibility of AA in pig feed ingredients is defined. Aspects of the methodology to establish bioavailability and ileal digestibility values also are discussed, and recommendations about the use of these values are provided. Two main factors can contribute to differences between bioavailability and ileal di...

A study was performed to: 1) compare total tract digestibility of nutrients for three annual summer forages: Mulato II (hybrid Brachiaria); “Tifleaf 3” Pearl Millet (Pennisetum glaucum); and “Hay Day” Sorghum sudan (Sorghum bicolor) and 2) determine the efficacy of two digestibility markers: titanium dioxide (TiO2) and chromic oxide (Cr2O3) used with a fecal sample collection protocol of either...

The apparent digestibility of energy, protein, fat and non-starch polysaccharides (NSP) of low and high dietary fibre (DF) mixed diets were studied in three series of experiments with man and the rat. Low DF diets were used as control diets in each experimental series and the DF level was increased by adding fruits and vegetables (Study 1), citrus fibre concentrate (Study 2) and insoluble barle...

This study was conducted with broilers to evaluate the effects of growth-promoting antibiotic (flavomycin) and probiotic (7 bacterial species) supplementation in diets containing soybean oil or free fatty acids (FFA) on performance, morphological parameters of the small intestine, apparent digestibility of gross energy (GE) in the ileum, and apparent digestibility of fat in the ileum and total ...

Two 2 × 2 factorial experiments were conducted to investigate the interaction between xylanase (0 vs. 200 mg/kg) and protease (0 vs. 200 mg/kg) enzyme supplementation on growth performance (Exp. 1) and coefficient of ileal and total tract apparent digestibility in grower-finisher pigs (Exp. 2). One hundred and twenty-eight individual fed pigs (BW = 34.2 kg; n = 32) were assigned to 1 of 4 dieta...

Musilova A., Lichovnikova M., Kupcikova L., Anderle V. (2017): Effect of suboptimal levels of non-phytate phosphorus and exogenous phytase on precaecal digestibility of phosphorus and calcium in laying hens. Czech J. Anim. Sci., 62, 473–481. The precaecal digestibility of phosphorus and calcium in laying hens was evaluated at two dietary levels of non-phytate phosphorus (NPP; 1.58 and 2.03 g/kg...

Twelve Dorper × Pelibuey wether lambs (26.8 ± 1.6 kg initial BW, 5 mo of age) were used to evaluate effects of zilpaterol hydrochloride (ZH) on feedlot performance, and effects of ZH and ZH supplementation period (15 and 30 d) on nutrient intake and digestibility. Lambs were blocked by initial BW, and assigned randomly within BW blocks to 1 of 2 treatments: i) control (no ZH), and ii) supplemen...

13 The nutritive value of 20 forage plants commonly used for feeding pigs in the Democratic 14 Republic of the Congo was studied to determine chemical composition, protein amino acid 15 profiles, mineral content, and in vitro digestibility using a two-steps method combining an 16 enzymatic pepsin and pancreatin hydrolysis followed by a 72h gas-test fermentation. The 17 highest protein contents ...

Dietary starch and proteins varies greatly in digestibility and its effects on the utilization of other nutrients. The variation appears to be due to differences in starch, protein and antinutrients affect the digestibility of foods. Processing treatments, storage conditions, chemical modification, and genetic breeding influence the digestibility of foods. Tempeh is a solid fermented soybean pr...
