Assessment of lighting needs by W-36 laying hens via preference test.
Light intensity, spectrum and pattern may affect laying hen behaviors and production performance. However, requirements of these lighting parameters from the hens' standpoint are not fully understood. This study was conducted to investigate hens' needs for light intensity and circadian rhythm using a light tunnel with five identical compartments each at a different fluorescent light intensity o...
متن کاملPerformance and Serum Hepatic Enzymes of Hy-Line W-36 Laying Hens Intoxicated with Dietary Carbon Tetrachloride
An experiment was conducted to study the effects of carbon tetrachloride (CCl4) on post-peak performance and serum enzymes of Hy-Line W-36 laying hens from 32-36 weeks of age. The experiment was carried out with a total of 192 laying hens in a completely randomized block design. During the experiment laying hens were allocated to 4 groups consisted of T1) no CCl4 as control diet, T2, T3 and T4)...
متن کاملPerformance and Serum Hepatic Enzymes of Hy-Line W-36 Laying Hens Intoxicated with Dietary Carbon Tetrachloride
Introduction In the modern poultry production, the birds are exposed to different stressful factors. Oxidative stresses produce free radicals suppressing the bird performance by disordering the body homeostasis. The liver is the best tissue to evaluate the oxidant-induced oxidative stresses. CCl4 is an important service today as a toxic agent model to induce oxidative stress on animals leading ...
