The Effect of Lentil-By Product on Growth Performance and Carcass Traits of Heavy White Turkeys
(Facta-fundacio Arnco Ciencia Tecnologia Avicolas, 2018) Sogut, B.; Kurbal, O. F.; Inci, H.; Ayasan, T.
The subject of this study was to figure out the effects of lentil by product (LP) on growth performance and carcass traits of the white heavy turkeys. To accomplish this goal, a total of 210 day old big-6 turkey chicks were used. The birds were divided into 7 seven groups with 3 replicates. The 1st, 2nd, 3rd, 4th, 5th, 6th and 7th groups received 0, 5, 10, 15, 20, 25 and 30 % lentil by product, respectively. All the diets were made as izonitrojenic and izocaloric. The highest live body weights of males and females were observed in the control group at the end of the 15th week, which was the time of slaughtering of females, however the differences between the control and the 2nd, 3rd and 4th groups were not significant (p>0.05). The same differences continued for males at the end of the 17th wk of age, which was the time of slaughtering of males. Similar results were observed in carcass traits, as well. The best FCR was noted in the control group and it was significantly (p<0.05) different than in the treatment groups. The lowest and highest feed intake was observed in the 7th and 3rd groups. No significant differences were observed between control and all treatment groups. As a result, it could be said that lentil by product could be added into turkey diets up to 15% with no negative effect on live body weight and carcass traits because there was no significant differences between control and treatment groups (5, 10,15 % LP).
Effects of Multi-Enzyme Supplementation in Wheat Based Quail (Coturnix Coturnix Japonica) Rations on Egg Production, Egg Quality and Some Blood Parameters
(Animal Nutrition Assoc, 2014) Tekeli, A.; Bilgecli, K.; Celen, F.; Kurbal, O. F.; Bitigic, M.
This study investigates the effects of multi-enzyme (xylanase, beta-glucanase, cellulase, pectinase, and protease) supplementation of wheat based quail rations on body weight, feed consumption, egg production, egg quality, feed conversion ratio and some blood parameters. A total of 210 eight-week old quails were distributed into five groups and fed diet supplemented with the multi-enzyme Rovabio Excel at 0 (Control), 0.5 (E-0.5), 1.0 (E-1.0), 1.5 (E-1.5) and 2.0 (B-2.0) kg/ton for a period of 12 weeks. Egg production and egg number increased (P < 0.01) in E-1.0 and E-1.5 groups but decreased (P < 0.01) in E-2.0. The highest (P < 0.05) average egg weight was obtained in the E-1.5 group, fed with 1.5 kg enzyme/ton. Albumen index significantly increased (P < 0.05) in all treatment groups compared to control group. The highest (P < 0.05) yolk index was recorded in the E-0.5 group fed with 0.5 kg enzyme/ton. Egg shape index increased (P < 0.05) in the E-1.0 and E-2.0 groups while the Haugh unit increased significantly (P < 0.05) in the E-1.0 and E-1.5 groups. However, egg size decreased (P < 0.05) with E-1.0. As a result, 1 and 1.5 kg enzyme/ton amounts of Rovabio Excel enzyme supplementation in wheat based quail rations increased egg production, egg number, average egg weight, albumen index, yolk index, egg shape index and Haugh unit, Minolta a* value. This results of this study suggest that multi-enzyme additives can be used to improve the performance quail fed on wheat based rations.
