DIMITROV, S. and T. ANGELOVA, 2001. Effect of different dietary protein level on body weight, feed consumption and biology ability of semen on turkey breeder males. Bulg. J. Agric. Sci., 7: 639-644
Body weight, feed consumption, sperm production and fertilizing ability of turkey breeder males fed with different protein levels were examined. Two groups (n = 6) male turkeys were fed ad libitum with 14 and 17 % protein. Dietary protein level had no effect on body weight – 13.800 ± 0.23 kg (14 % protein) and 15.100 ± 1.05 kg (17 % protein); feed consumption – 0.462 ± 0.02 kg (14 % protein) and 0.469 ± 0.03 kg (17 % protein); semen concentration – 3.374 ± 0.18 × 109/ml (14 % protein) and 3.629 ± 0.11 × 109/ml (17 % protein). Protein level had effect on semen volume – 0.18 ± 0.02 ml (14 % protein) and 0.21 ± 0.11 kg (17 % protein); motility of semen – 64.43 ± 13.01 % (14 % protein) and 72.59 ± 21.70 % (17 % protein); fertility – 84.30 % (14 % protein) and 79.98 % (17 % protein) (P < 0.01).
