Effect of dietary mannan oligosaccharide on broiler breeder production traits and immunity.

The effects of mannan oligosaccharide (MOS) supplementation in broiler breeder diets on egg production, hatchability, fertility, and immunity were examined by randomly allocating 60-wk-old breeders to eight replicates (four replicates of two diet treatments) in a cage trial, and 42-wk-old broiler breeders to 12 replicates (six replicates of two dietary treatments) in a deep litter trial. Breeders were fed corn-soybean meal based diets with (MOS group) or without MOS or antibiotics (control group). Egg production, hatchability, and related parameters were measured for 8 and 12 wk in the cage trial and deep litter trial, respectively.

Efficacy of esterified glucomannan to counteract mycotoxicosis in naturally contaminated feed on performance and serum biochemical and hematological parameters in broilers.

A study was conducted to determine the efficacy of esterified glucomannan in counteracting the toxic effects of mycotoxins in naturally contaminated diet (aflatoxin 168 ppb, ochratoxin 8.4 ppb, zearalenone 54 ppb, and T-2 toxin 32 ppb) fed to commercial broilers. One-day-old broiler chicks were randomly assigned to one of the four dietary treatments with five replicates of 14 chicks each.

Evaluation of glucomannan for its adsorbing ability of Aflatoxin B1 and T-2 Toxin in the Gastrointestinal Tract of Broiler Chickens.

A biological experiment was conducted to evaluate the ability of glucomannan to adsorb aflatoxin B1(AFB1 and T-2 toxin in gut conditions of broiler chickens. Glucomannan (GM) was tested at 0.1 percent (1kg / ton) on a total of two hundred uniformly weighing five-week-old commercial broiler birds, which were randomly assigned to one of the ten dietary treatments with four replicates each.

In vitro evaluation of nonstarch polysaccharide digestibility of feed ingredients by enzymes.

Some of the commonly used feed ingredients for poultry (corn, sorghum, finger millet, deoiled ricebran, soybean meal, peanut meal, sunflower meal, and rapeseed meal) were screened for pentosans, cellulose, pectin, and total nonstarch polysaccharides. The ingredient in vitro digestibilities by enzymes were evaluated. Cereal samples screened contained mainly pentosans.

Influence of esterified-glucomannan on performance and organ morphology, serum biochemistry and haematology in broilers exposed to individual and combined mycotoxicosis (aflatoxin, ochratoxin and T-2 toxin).

1. A study was conducted to evaluate the individual and combined effects of aflatoxin B1 (AF), ochratoxin A (OA) and T-2 toxin (T-2) on performance, organ morphology serum biochemistry and haematology of broiler chickens and the efficacy of esterified-glucomannan (E-GM), a cell wall derivative of Saccharomyces cerevisiae1026 in their counteraction. 2.
