| Summary: | <b>Aim:</b> This study was carried out to investigate the effect of different rearing
conditions on the growth and fattening performance of American bronze
turkeys.<p>
<b>Materials and Methods:</b> In the study, data from a total of 123 American
bronze turkeys were analyzed. The hatchlings, whose hatching weight was
measured, were reared together for the first 10 weeks, and then divided into
the experimental groups. The intensive rearing system group (control group)
was fed only with concentrated ad libitum. Pasture groups are semi-intensive
and extensive rearing systems. The semi-intensive group was subjected to
75% restricted feeding of the concentrate that the intensive group should
consume. The turkey flock in the extensive rearing system was fed 50% of the
feed that the turkeys in the intensive rearing system group should consume.
Pasture groups benefited from the pasture between 09:00-17:00. The
growth and fattening performances of the turkeys were examined by regular
weighing and measurements every two weeks as they were being reared in
these growing conditions between the ages of 10-32 weeks.<p>
<b>Results: </b>The 32-week live weights of turkeys were found to be 4.60-4.70
and 4.52 kg in females and 7.58-7.79 and 6.71 kg in males, in intensive,
semi-intensive, and extensive systems, respectively. The effect of the rearing
system was significant in males at 12-32 weeks, moreover, a difference was
determined among groups in females at 14-28 weeks.<p>
<b>Conclusion: </b>As a result of, American bronze turkeys can be suitable breed for
pasture conditions. Based on the live weight gain and feed efficiency values of
the study groups, this breed can continue to grow for longer than 32 weeks
when quality pastures are provided. |
