Effects of guar meal by-product with and without beta-mannanase Hemicell on broiler performance.
Hemicell significantly improved feed:gain ratio of diets containing 5% of each fraction of guar meal versus the untreated diets, and addition of beta-mannanase (HemICEll) increases the upper feeding level for the germ fraction to 5%.
Use of guar by-products in high-production laying hen diets.
It was shown that both guar germ and guar meal can be fed to high-production laying hens at up to 5% without adverse effects on laying hen performance.
Incubation temperature for ostrich (Struthio camelus) eggs.
The impact of incubation temperature on egg weight loss, embryonic mortality, incubation period, hatchability, and chick weight in 394 ostrich eggs was studied and it is shown that the most effective incubationTemperature for the ostrich is lower than the mosteffective incubation temperatures for most bird species.
Effect of early feed restriction on reproductive performance in Japanese quail (Coturnix coturnix japonica).
Although hatchability was unaffected by feed restriction, percentage of late dead and total dead embryos were significantly reduced in eggs from restricted quail and thirty quail fed 70% of ad libitum control intake had significantly increased egg specific gravity.
Adipose cellularity in Gallus domesticus: investigations to control body composition in growing chickens.
Adipose tissue development and body composition are affected by hormone levels in growing chickens and possible approaches to modulate fat deposition and adipose cellularity in poultry are reviewed.
Hemolytic and Antimicrobial Activities Differ Among Saponin-rich Extracts From Guar, Quillaja, Yucca, and Soybean
Hemolytic and antibacterial activities of eight serial concentrations ranged from 5-666 µg/mL of saponin-rich extracts from guar meal (GM), quillaja, yucca, and soybean were tested in 96-well plates
Effect of acetyl salicylic acid in drinking water on reproductive performance of Japanese quail (Coturnix coturnix japonica).
Adding 1.5 g/L ASA to the drinking water of quail under heat stress improved body weight, fertility, hatchability, embryonic mortality, egg production, egg specific gravity, and sperm storage capacity.
Effect of feeding time on the reproductive performance of Japanese quail (Coturnix coturnix japonica).
Results showed that selection of the time of day for application of an 8-h restricted feeding regimen affected BW, fertility, hatchability, egg production, egg specific gravity, and oviposition time in Japanese quail.
Fatty acid turnover rates in the adipose tissues of the growing chicken (Gallus domesticus)
The data suggest that fatty acids were released from a more labile adipose site and subsequently reincorporated into abdominal and sartorial tissues and that fat mobilization occurred at the same time as did adipose tissue deposition in the growing chicken.
