Comparison of growth performances of American Bronze, Large White turkeys and their crosses under intensive and semi-intensive management conditions.

Résumé fourni par la source

Between 1970 and 2005 turkey meat production in Turkey increased from 4.66 to 12.1 thousand tons or by 2.59 fold. Within this period, global turkey meat production increased from 1,224 to 5,767 thousand tons or by approximately five times (FAO, 2008). Over a long period of time native American Bronze turkeys were used for meat production in Turkey. However, during the last 10 years, high demands for poultry meat in Turkey made the use of foreign genotypes necessary. Therefore, hybrid genotypes, especially hybrid large white turkeys, replaced the traditional use of American Bronze turkeys. These Hybrids are the result, as it is for Large White turkeys, of 3or 4-line crosses (NESTOR et al., 2005). American Bronze turkeys which are still the predominant breeds in Turkey are characterized by small body size, lower egg production and hatchability (TURKOGLU et al., 1990; TURKOGLU et al., 2005). The objective of this study was to compare and assess the growth performances of the American bronze, foreign hybrid large white turkey (Hybrid Converter) and different combinations of their crosses raised under intensive and semi-intensive management conditions.
