“…In evaluating two strains of commercial turkeys (British United Turkey and Nicholas), Brenøe and Kolstad (2000) observed that the strains did not differ in live weight with an average bi-weekly LWG of 1584.4 g between 4 and 17 weeks old, a value which was slightly higher than the performance that was achieved in the intensive production system of the present study. Ad libitum or limit-feeding methods may be applied in feeding turkeys (Tumova et al, 2002;Mejia et al, 2010;Mejia et al, 2011;Sgavioli et al, 2013). Cetin et al (2001) indicated that feed could be restricted to turkeys at up to 14% of ad libitum without lowering LWG.…”

The aim of this study was to determine the effect of three production systems on live weight gain (LWG) of white turkeys by repeated measures analysis of variance (ANOVA) and profile analysis. A total of 81 turkey poults were assigned to intensive (7 male and 19 female), semi-intensive (9 male and 19 female) and extensive groups (11 male and 16 female) at one day old. The poults were wing-banded at day 1 after hatching and weighed individually each week through 16 weeks old. The birds were managed similarly through eight weeks old. After that time, the intensive group was fed concentrated feed indoors. The birds of the semi-intensive group had access to pasture for eight hours a day, and received 50% of the concentrated feed that was consumed by the intensive group. The birds in the extensive group were kept outdoors with shade and grazed on pasture, but did not receive concentrated feed. The bi-weekly LWG of the extensive, intensive and semi-intensive groups were 1191.4 g, 990.6 g and 872.1 g, respectively. Through the 16 weeks of the trial, the effects on LWG of production system, age, and interaction of age and production system were highly significant (P <0.01) in the repeated measures ANOVA. The profile analysis also showed highly significant (P <0.01) production system effects and interaction of production system and age on LWG. Scheffe’s test indicated that the intensive, semi-intensive, and extensive treatments differed (P <0.05).
