15 صفحه اولInfluence of particle size and calcium source on production performance, egg quality, and bone parameters in laying ducks.
The influence of calcium source (limestone and oyster shell) and particle size (<0.1 mm; 0.85 to 2 mm) on laying performance, egg quality, and bone properties were examined in laying ducks by a 2 × 2 factorial arrangement of treatments. Longyan females (288) with similar BW at 24 wk of age were randomly allotted into 4 treatments, each with 6 replicates of 12 individually caged birds and studied...

Substitution Effect of Noug Seed (Guzoitia abyssinica) Cake with Various Levels of Samma (Urtica simensis) Leaf Meal on Egg Production and Egg Quality Parameters of Commercial Layer Hens
The substitution effect of noug (Guzoitia abyssinica) seed cake with samma (Urtica simensis) leaf meal (SLM) was investigated on egg production and egg quality parameters in commercial layer hens. Five treatment (T) diets were formulated to contain SLM at 0% (T1), 3% (T2), 6% (T3), 9% (T4) and 12% (T5) by substituting noug seed cake. One-hundred fifty Isa Brown layer pullets w...
