Yolk and albumen corticosterone concentrations in eggs laid by white versus brown caged laying hens.
Maternal stress in birds can have permanent transgenerational effects through the transmission of stress hormones to offspring via the egg yolk. Previous studies have shown that White Leghorn hens show a heightened response to stress compared with Hy-Line Brown hens, producing significantly more corticosterone and displaying longer bouts of tonic immobility after handling, whereas baseline leve...
متن کاملAppraisal of Hematological Indices and Humoral Immunity in Commercial Laying Hens Fed Rations Consisting Cottonseed Meal and Sodium Bentonite
The objective of this study was to evaluate the effects of cottonseed meal (CSM) treated with sodium bentonite (SB) on certain blood components and immune response of laying hens. A 3 × 3 factorial arrangement with 3 levels of SB (0, 10, and 20 g/kg of diet) and 3 levels of CSM (0, 100 and 200 g/kg of diet) were used within 9 dietary treatments of 4 replicates each. Nine mash diets were fed to ...
متن کاملEffect of Tomato Waste Meal on Lay Performance, Egg Quality, Lipid Profile and Carotene Content of Eggs in Laying Hens
An eight week study was conducted to investigate the effect of inclusion of tomato waste meal in layer diets on laying performance, egg quality and lipid profile as a means to reduce feed cost and pollution. Four laying diets containing tomato waste meal (TWM) at four levels of 0, 3, 6 or 9% were assigned randomly to 4 groups of 40 birds divided among four replicates of 10 birds in each dietary...
متن کاملAflatoxin B1 Residues in Eggs and Flesh of Laying Hens Fed Aflatoxin B1 Contaminated Diet
Aflatoxin B1(AFB1) and total Aflatoxins (AFT) contaminated feed effect on aflatoxins residue level in eggs, muscles (breast, leg), organs (liver, kidney, gizzard) and excreted aflatoxins in chicken litter of layer hens were monitored. Laying hens were on four levels of aflatoxins for 6 weeks and monitored weekly for the change in both AFB1 and AFT levels. Pronouncedly, the AFB1 and AFT were det...
متن کاملRequirement of Digestible Sulfur Amino Acids in Laying Hens Fed Sorghum- and Soybean Meal-Based Diets
Two experiments were done to evaluate the effect of increasing levels of dietary digestible methionine (Met) and Met:cysteine (Met:Cys) ratio on the productivity of Hy-Line W-36 laying hens fed sorghumand soybean meal-based diets. In Exp. 1, 160 hens from 68 to 75 weeks of age were assigned to four dietary levels of digestible Met (0.20 0.24, 0.28 and 0.32%). The digestible total sulfur amino a...
