Response of Broiler Chickens to Quantitative Feed Restriction with or without Ascorbic Acid Supplementation
Ascorbic acid (vitamin C) supplementation has been documented as a useful tool to improve the performance of laying birds reared under harsh environmental conditions. However, there is limited information on the use of ascorbic acid as a means of ameliorating the stressful conditions imposed by feed restriction. To this effect a 3 × 2 factorial experiment was carried out to evaluate the effect ...
متن کاملEffect of lighting stress on fluctuating asymmetry, heterophil-to-lymphocyte ratio, and tonic immobility duration in eleven breeds of chickens.
The purpose of the present study was to analyze the effect of a lighting stress on the fluctuating asymmetry (FA), the heterophil-to-lymphocyte ratio, and the tonic immobility duration of chickens. The experiment (440 birds) measured the FA of several traits (outer, middle, inner, and hind toe lengths and leg, wing, second primary feather, and spur lengths), the heterophil-to-lymphocyte ratio, ...

15 صفحه اولRelationships between bilateral asymmetry and tonic immobility reaction or heterophil to lymphocyte ratio in five breeds of chickens.
Bilateral asymmetry of several morphological traits, tonic immobility reaction, and leucocyte ratio were studied in hens and cocks from four Spanish breeds of chickens (Castellana, Buff Prat, Red Villafranquina, and Barred Red Vasca) and an F2 cross between Castellana and Buff Prat (C x BP - F2). Any two or all three types of bilateral asymmetry (fluctuating asymmetry, directional asymmetry, an...
