Abstract
This retrospective single-loft observational record analysis evaluated reproductive records from the first breeding season of Malta-type foster canaries (Serinus canaria domestica) managed under two domestic commercial egg-food and seed combinations. Breeding records from a single loft were reviewed from early February to early August of the same year. Both feeding combinations consisted exclusively of commercially marketed products manufactured in Türkiye. Males were housed individually until the breeding season, whereas females were maintained in groups of five. After pairing in early February, birds were managed with either domestic X-brand egg food plus Y-brand domestic canary mixed seed or domestic A-brand egg food plus B-brand domestic canary mixed seed (n = 5 pairs per combination). Birds were housed in specially designed roll-system PVC breeding cages (50 × 40 × 40 cm) and completed four clutches with their own eggs and chicks, without being used as foster parents during the evaluated period. Egg number per clutch, chick number per clutch, seasonal totals per pair, and hatchability were evaluated. The pair was accepted as the independent observation unit. Exact Mann–Whitney U tests were used for between-combination comparisons where applicable, with Cliff’s delta as the effect size. The Friedman test was used for within-combination clutch effects, and Holm-corrected Wilcoxon signed-rank tests were used for pairwise comparisons when required. Seasonal total egg number per pair was 16.2 ± 0.8 in the X+Y combination and 15.8 ± 1.3 in the A+B combination (exact P=0.841). Total chick number was 14.6±1.5 and 13.4±1.8, respectively (exact P=0.421). Hatchability was 90.1±7.2% in the X+Y combination and 84.7±7.2% in the A+B combination (exact P=0.310). Egg numbers followed a similar course across four clutches in both combinations. Chick number declined as the season progressed when all pairs were evaluated together, but no formal group × clutch interaction model was fitted. In conclusion, no between-combination difference was detected in seasonal egg output, chick output, or hatchability in this small retrospective observational dataset. The findings should be interpreted as exploratory and descriptive rather than confirmatory.
