Effects of Levels of Inclusion of Locally Processed Fish Waste Meal in the Diets of White Leghorn Layers on Performance Parameters, Hatchability, Economics, Egg Production and Egg Quality
The study was conducted at Haramaya university poultry farm to evaluate the effects of locally processed fish waste meal (FWM) in the diet of white leghorn layers on the performance and hatchability, egg quality, sensory flavor and profitability of the rations. One hundred eighty chickens at five months of age were randomly distributed (15 layers per each 12 pens). The pens were randomly assign...
متن کاملEgg production curve fitting using nonlinear models for selected and nonselected lines of White Leghorn hens.
Egg production curves describe the laying patterns of hen populations over time. The objectives of this study were to fit the weekly egg production rate of selected and nonselected lines of a White Leghorn hen population, using nonlinear and segmented polynomial models, and to study how the selection process changed the egg-laying patterns between these 2 lines. Weekly egg production rates over...
متن کاملComparative effects of furnished and battery cages on egg production and physiological parameters in White Leghorn hens.
Laboratory animal well-being can be improved by housing the animals in species-specific natural or near-to-natural environments. An enriched environment may have a similar effect on chickens. The purpose of this study was to examine if housing environment (furnished cages vs. battery cages) effects the well-being of laying hens. One hundred ninety-two 1-d-old non-beak-trimmed White Leghorn W-36...

متن کاملEffects of mycotoxin-contaminated diets and deactivating compound in laying hens: 2. effects on white shell egg quality and characteristics.
An experiment was conducted to determine the effect of dietary inclusion of Mycofix Select (Biomin GmbH, Herzogenburg, Austria) on discrete egg parameters and quality characteristics of hens fed mycotoxin-contaminated diets (aflatoxin; AFLA) and deoxynivalenol (DON)) during a 10-wk trial. A 4 × 2 factorial design was used with 4 contamination levels: control, low (0.5 mg/kg of AFLA + 1.0 mg/kg ...
