Subject(s): Online resources: In: Egyptian Poultry Science Journal 2015.v.35(II)Summary: This experiment aimed to study the impact of photoperiod-length and light source on semen quality, physiological responses and some blood parameters in rabbit bucks. Twenty Bouscat bucks were equally assorted to two experimental groups. In the first group (control), bucks were exposed to a long photoperiod (16Lhrs), while those of the second were subjected to a short photoperiod (6Lhrs). In each group, bucks were classified into two equal subgroups. The lighting source in the first subgroup of both lighting regimens was the incandescent lamp, while the compact saving lamp was used in both of the second subgroup. All bucks were individually housed in wire galvanized battery cages and raised under similar normal managerial conditions. The obtained results could be concluded as follow: 1- The ejaculate volume (ml), advanced motility (%) and total sperm output/ejaculate×106 of bucks exposed to the long photoperiod (16Lhrs) increased significantly than those of the short photoperiod (6Lhrs), while their sexual libido (sec) and sperm abnormalities (%) decreased significantly. 2- The advanced motility (%) and sperm output/ml×106 of bucks exposed to light produced from incandescent lamps increased significantly (P<0.05) than those of bucks subjected to light from saving lamps. Key Words: Rabbit Bucks, Semen Characteristics, Photoperiod And Light Source.
