a 3*2*2 factorial experiment was conducted to study the effect of feeding whole wheat (0, 10, and 20%), a microbial enzyme source (arabino-xylanase based enzyme for wheat at 0% and 0.1%) and 0% or 1% insoluble grit (number 3 layer size) on the performance of white leghorn hens at 19 to 54 weeks of age. each dietary treatment was replicated four times with ten hens, housed two to a cage, eac...

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...

The embryonic modal value of heart rate (MHR) differs between broiler and White Leghorn chickens, but the initial development of cholinergic chronotropic control of embryonic heart rate (HR) does not. Thus, we hypothesized that hatchling MHR should also differ between broiler and White Leghorn strains, while the development of a physiological regulation, such as the endothermic HR response, sho...

Genetic interrelationship within and between strains was assessed using pure Nigerian normal feathered local, pure exotic and their crossbred hens for age and body weight at first lay, egg weight and egg internal quality traits. 100 layers comprising 20 Black Nera, 20 White Leghorn, 20 Normal feathered local chicken, 20 White Leghorn x Local cross and 20 Black Nera x Local crosses were randomly...

Poultry farming not only provides high nutritious food but also creates employment opportunity for rural masses. Documented evidences elaborates that helminth parasitism is most deciduous problem of chickens especially in developing world. Ascaridia (A.) galli, a nematode of small intestine, has been considered as the most common and important parasite of chicken. The present study was carried ...
