The Effect Of Grower Diet Protein Level On The Performance And Some Slaughtering Characteristics Of Sex-Separated And Mixed- Sex Broilers, Veysel Ayhan, Mehmet Bozkurt, Kami̇l Küçükyilmaz

Turkish Journal of Veterinary & Animal Sciences

This trial examined 1350 sex-separated broilers at 24 days of age. Chicks were fed standard broiler starter diet for the first 21 days. Isocaloric grower diets (16.84%, 18.00% and 19.46% crude protein, respectively) were offered to broilers housed in sex-separated and mixed-sex pens from days 24 to 45 of the experimental period. While the body weights of sex-separated and mixed-sex broilers were similar, diet protein level and sex had a significant effect on the body weight of broilers during the experimental period (P < 0.01). Male broilers consumed more feed and had better feed conversion than females (P < 0.01). However, separate sex rearing had no significant effect on feed consumption or feed conversion rate (P > 0.05). As diet protein level decreased feed consumption increased numerically and feed conversion was negatively affected (P …

Anaesthetic Effects Of Quinaldine Sulphate Together With The Use Of Diazepam On Oreochromis Niloticus L. 1758 (Cichlidae) At Different Temperatures, Mahmut Yanar, Ercüment Genç

Turkish Journal of Veterinary & Animal Sciences

The anaesthetic effects of quinaldine sulphate (QS) together with diazepam (D) on tilapia (Oreochromis niloticus) (20-25 g) were studied at different temperatures. The application of QS with D significantly increased the anesthesia level of QS in the fish. Depending on temperature, the fish entered light or deep anesthesia levels with the use of QS alone at 10 or 35 mg/l, compared to 5 or 20 mg/l when used together with D (1-2 mg/l). In addition, when used together with QS, D eliminated the excitement and hyperactivity of the fish compared to QS alone. A rise in temperature from 18 °C …
