Determination of Fermentation and Digestibility Characteristics of Corn, Sunflower and Combination of Corn and Sunflower Silages
(Medwell online, 2008) Demirel, M.; Bolat, D.; Celik, S.; Bakici, Y.; Eratak, S.
This study was conducted to determine in vivo digestibilities and fermentation property of various silages made of green herbage of Sunflower (SF), Corn (C) and corn-sunflower mixtures at different rates [75% com+25% sunflower (75C25SF), 50% corn+50% sunflower (50C50SF), 25% corn+75 sunflower (25C75SF)] ensiled in 120 1 plastic barrels for 90 days. PH values of C and mixture silages were lower than that of SF silage (p<0.05). Concentrations of lactic, acetic, propionic and butyric acids were higher in SF silage than C silage (p<0.05). Lactic and propionic acid concentrations increased in mixture silages as the sunflower ratio increased, whereas decreases in butyric acid concentration were observed as corn ratio incresed in the mixture (p<0.05). While digestibility of DM, OM, ADF and NDF were high in C silage, digestibility of CP and EE were high in SF silage. The digestibility of DM, OM, ADF and NDF in mixture silages increased with the increases in corn ratio in mixture and digestibility of CP and EE of increased as sunflower ratio increased in mixture. It can be concluded that high quality silages could be obtained from green herbage of corn or sunflower alone, however their nutritive values could be improved if they are mixed at 50% ratio.
Effect of Salinomycin on Broiler Performance
(2006) Demirulus, H.; Eratak, S.; Kara, K.
In this study, effects of salinomycin on broiler performance were evaluated. Six levels of salinomycin added to feed were tested (0, 1, 3, 5, 7 or 9 ppm, respectively) for 49 days. Increasing the level resulted in a decrease in body weight, feed intake, weight gain and feed efficiency. The highest body and neck weight (1972.5 and 90.9 g) and the best feed efficiency (1.59) were obtained with 1 ppm salinomycin (p<0.05). The best viability rate (96%) was obtained with 3 ppm salinomycin (p<0.05). The highest plucked, carcass, tight, wing, breast and back weight of the group were 1629.1, 1316.9, 399.0, 150.0, 440.0 and 300.7 g, respectively. The highest abdominal fat weight (36.8 g) observed with 7 ppm salinomycin used group (p<0.05). © 2006 Asian Network for Scientific Information.
