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 کاملA Genome-Wide SNP Scan Reveals Novel Loci for Egg Production and Quality Traits in White Leghorn and Brown-Egg Dwarf Layers
Availability of the complete genome sequence as well as high-density SNP genotyping platforms allows genome-wide association studies (GWAS) in chickens. A high-density SNP array containing 57,636 markers was employed herein to identify associated variants underlying egg production and quality traits within two lines of chickens, i.e., White Leghorn and brown-egg dwarf layers. For each individua...
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...
