Effect of dietary supplementation of herbal seeds on carcass traits of turkey poults

Abstract

Aim: The present study was conducted to find the effect of four herbal seeds on carcass traits of turkey poults. Materials and Methods: A biological study using Nandanam turkey poults (Meleagris gallapavo) for 8 weeks duration was carried out to evaluate the effect of phytobiotics-containing four herbal seeds influence on production performances like biweekly body weight and on carcass traits. 150 poults were randomly subjected to five dietary treatments in a completely randomized design with basal diet (T1), 0.5% (5 g/kg) level of each seeds thyme (Thymus vulgaris) (T2), fenugreek (Trigonella foenum graecum) (T3), fennel (Foeniculum vulgare) (T4) and cumin (Cuminum cyminum) (T5). Carcass traits like blood loss, feather loss, dressed weight, New York dressed weight, ready to cook yield and cut-up parts yield were studied. Results: The body weight at 8th week was higher (p<0.05) in poults fed with thyme; whereas at 6th week, fennel and cumin fed birds had better (p<0.05) body weight. Inclusion of herbal seeds did not affect the blood loss, dressed weight and ready to cook yield but it significantly (p<0.05) affected the feathered loss, New York dressed weight and giblet percentages. Feeding of fenugreek has improved New York dressed weight of poults. Feeding of fennel had depressive (p<0.05) effect on liver and gizzard weights. All the four phytobiotic seeds in feed had significant (p<0.05) reduction in breast weight with a compensatory improvement in drumstick and neck weights. Conclusion: The present study revealed that supplementation of phytobiotic herbal seeds has resulted in numerical improvement of body weight of poults throughout the study period whereas these seeds had negative effect on the yield of breast, with increased proportion of drumstick and neck.
