| Popis: |
Flock records from a commercial turkey company were analyzed to determine if poult source affected flock performance. Comparisons were made between flocks supplied by two hatcheries (X and Y) reared on the same farms and among flocks reared on different farms. Flocks from hatchery X had significantly better livability and feed-conversion ratios than flocks from hatchery Y. Although not statistically significant, flocks from hatchery X tended to grade better at processing (percent grade A) and have lower condemnations than flocks from hatchery Y. Season significantly affected livability and feed conversion of all flocks regardless of hatchery source. |
