Evaluation of seasonal breeding of the domestic canary (Serinus canaria) in an artificial environment

ABSTRACT: The domestic canary (Serinus canaria) has been bred for hundreds of years to improve the quality its plumage and song. Reproduction in this species occurs seasonally, stimulated by a gradual increase day length. Although, occurrence seasonal breeding canaries is well known, whether reproduction can be manipulated remains unknown. Our objective was determine conditions captivity (photoperiod temperature) adjusted enable reproduce outside their natural season. Thirty days before season, pairs were assigned separated into three different groups: External Control (housed outdoors under ambient conditions), Artificial artificially indoors similar external Altered five months, with photoperiod gradually simulate that season) groups. number clutches laid greater than Control; however, more birds hatched Control. In group, beginning season delayed when same parameters used. further research needed, study presents new data assist development protocols entail changes environmental try reduce impacts processes on animal welfare.
