Effect of Aflatoxicosis on Hatching Egg Quality Parameters of Broiler Breeders
نویسنده
چکیده
A study was conducted to investigate the effect of feeding diets containing different levels of aflatoxin B1 (AF) viz., 0, 300, 400 and 500ppb on the hatching egg quality of broiler breeders. The breeder hens aged 28 weeks were fed with four treatment diets: Control (0ppm), (300 ppb), (400 ppb) and (500 ppb) for three periods, each with a duration of three weeks from 28 to 36 weeks of age. Feeding of AFB1 at 300 and 400ppb did not reveal any significant changes in the hatching egg quality. However, Inclusion of 500ppb AF in the diet significantly (P≤0.05) reduced feed consumption, feed efficiency, egg production, fertility and hatchability. The results indicated no significant (P≥0.05) effect of AF on body weight of breeders.

A study was conducted with an objective to compare the efficacy of bentonite (BT), Spirulina platensis (SP) and glucomannan mycotoxin binders (GMA) on aflatoxicosis in broiler breeders. Three levels of AF, three binders and combination of different levels of AF with binders were evaluated. The Aflatoxin B1 (AF) fed at the levels of 300, 400 and 500ppb for three periods, each with duration of th...

A total number of 5520 female and 480 male breeders (Arbor Acres plus) at 42wks of age were used in a 10-week-trial to investigate the effect of an enzyme complex on the quality and quantity of egg production as well as hatchability of broiler breeders fed a corn-soybean meal diet. There were two dietary treatment groups: a control group fed on a corn-soybean based diet, and the multi-enzy...

Chick embryo development is associated with an accumulation of polyunsaturated fatty acids in lipid tissues making them susceptible to lipid peroxidation. It has been accepted that canthaxanthin has high antioxidant capacity. Research findings have repeatedly indicated that feeding 25(OH)D3 (25-hydroxycholecalciferol), to poultry breeders, broilers and layers increased performance and health. T...
