| Özet |
| This research was conducted to determine effects of dietary Nigella sativa oil levels (0, 1, 2, 3 ml/kg) on performance, egg quality, triglyceride, cholesterol and some proteins ratio of egg yolk and Escherichia coli count in feces of laying hens. Sixty four 26 weeks old white Lohman LSL laying hens were randomly assigned to four groups equally (n = 16). Each treatment was replicated four times Dietary supplementation of Nigella sativa oil had no significant effect on feed intake, feed conversion ratio, egg weight, and egg production, ratio of yolk, albumen and shell. The addition of 3 ml/kg Nigella sativa oil to laying hens feed led to a significant decrease in the Haugh unit of the egg. It was also observed that E. coli concentration of feces samples were reduced significantly (P < 0.05) with supplementation of Nigella sativa oil to laying hen diets. Supplementation of 3 ml/kg Nigella sativa oil exhibited higher antimicrobial activity than for the other groups. The lowest cholesterol ratio of egg yolk was obtained from hens fed 1 and 2 ml/kg Nigella sativa oil. Although, supplementation of 3 ml/kg Nigella sativa oil decreased ratio of egg triglyceride, it resulted in the highest egg yolk cholesterol. The addition of 2 and 3 ml/kg Nigella sativa oil to laying hens feed led to a significant decrease in egg albumin and conalbumin ratio. © Verlag Eugen Ulmer, Stuttgart. |
