Following a laying cycle of 100 days, turkey hens received one of the following treatments: (1) darkhouse-molted, (2) darkhouse-nonmolted, and (3) conventional house-molted. After an 8 week darkhouse treatment, the hens were caged for another 100 day production period. Birds in groups which were darkhoused laid at approximately 80% of that observed in the first cycle. Highly significant (P ≦ .01) positive correlations for production were obtained in the darkhoused groups between cycles. Those darkhouse hens not molted had the highest between cycle correlation. Those maintained in a conventional house and molted did not lay as well in the second cycle. The correlation between individual hen records for this group was −0.03 and nonsignificant statistically. |
