    Effect of probiotic supplementation shortly before and after weaning on growth of Turkish Saanen kids
    (Archiv Fur Tierzucht, 2005) Ayisigi, K; Atasoglu, C; Yurtman, SY; Mendes, M; Pala, A
    Sixteen kids were assigned at an average of 6 weeks of age to two treatments: control with no supplementation and 5 g/kid of probiotic supplementation daily. The probiotic was resuspended in distilled water and given orally every day in the morning throughout a 42 d study. Grower concentrate, vetch hay and water were offered ad libitum throughout the study. Kids were abruptly weaned 14 days after the initiation of the study and received only grower concentrate, vetch hay and water ad libitum from d 15 to 42. The supplementation of probiotic did not result in any significant differences in weight gain, nutrient intake, feed efficiency and diarrhea score in kids. However a positive trend toward improved weight gain, feed intake and feed efficiency in kids supplemented with probiotic suggested that probiotic might improve growth and performance of kids and are worth further investigation.

    Effects of three different lighting programs on live weight change of bronze turkeys under semi-intensive conditions
    (Archiv Fur Tierzucht, 2005) Mendes, M; Karabayir, A; Ersoy, IE; Atasoglu, C
    A study was conducted to evaluate the influence of three lighting programs (23L: 1D), (18L: 6D), and (12L: 12D) on live weight changes of American Bronze turkeys by Profile analysis technique. The F-statistics and Wilk's Lamba statistics for testing group-response interaction or similar profiles suggested that there was a significant interaction effect (p<0.01). The effects of the three lighting programs on live weight gain appeared to be different throughout the study except for the last 6 weeks. On the other hand, the results of the present study suggested that the effect of the three lighting programs on live weight gain followed a similar trend or three lighting programs had similar physiological effect on live weight gain from 10(th) week on wards.

    Growth curve establishment for American Bronze turkeys (short communication)
    (Archiv Fur Tierzucht, 2006) Ersoy, IE; Mendes, M; Aktan, S
    The purpose of this study was to establish the growth curves parameters of American Bronze turkeys. The weekly body weight changes of male and female turkeys were recorded during 11 to 24 weeks of age. The Richards' growth model fitted the turkey weight and age (week) data. Profile analysis was also applied to Weight-age data in order to get more detailed information about the differences in the five weights of male and female turkeys in consecutive weeks. Estimates for mature body weight were found as 9720.40 +/- 971.33 and higher for males than for females as 6029.96 +/- 316.55 g. Based on Richards' model, male turkeys matured more slowly and it was needed that a more time to reach mature body weight than female turkeys. Results of profile analysis supported those results. Estimates for the absolute growth rate, absolute maturing rate and relative growth rate values were higher for females when compared to males. Male turkeys reached the maximum growth rate at 16.30 weeks of age whereas female ones reached the maximum growth rate at 12.85 weeks of age. Live weights of male and female turkeys, when both reached the maximum growth rate, were 3475.61 and 2156.06 g, respectively. Male turkeys reached 80% of their mature weights at 24 weeks of age, whereas female ones reached 92% of their mature weight.

    The relationship among pre and post slaughter traits of American Bronze Turkey
    (Archiv Fur Tierzucht, 2005) Mendes, M; Karabayir, A; Ersoy, IE; Savas, T
    This study aimed to investigate the relations among the pre- and post-slaughter traits of American bronze turkeys. Birds were raised under three different lighting regimes. Pre-slaughter traits were measured when the birds were 15-, 20-, and 30-weeks of age. Canonical correlation analysis showed that as the birds aged the relations among the pre- and post-slaughter characters became more pronounced, Coefficients of determination (R-2) were 63.6-82.8% when pre-slaughter characteristics were measured at the 15(th) week, 84.8-94.6% at the 20(th) week, and 91.3-99.1% at the 30(th) week, respectively.
