The Effect of Litter Type and Litter Thickness on Broiler Carcass Traits
(2006) Demirulus, H.
In this research, straw and pine shavings were used as litter. Litter thicknesses were 5, 8 and 11cm respectively. 18 chicks were placed per m 2 and total 120 chicks were used in 3 groups. The study was performed two replicates. According to results of the investigation, the best live weight (1.67±0.11 kg) and carcass weight (1135.06±84.47g), heart weight (10.48±1.68g), liver (38.39±5.51g) and gizzard weight (37.10±4.40 g), and carcass yield (67.90±3.2%) were obtained from 5cm-pine shaving group. These results were significantly higher than the results of 11cm-straw and 11cm mixed form. Desired lowest abdominal fat level (17.28±2.6 kg) and feed efficiency rate (2.25) were also obtained from pine shavings of 5 cm thickness. © Asian Network for Scientific Information, 2006.
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.
Growth Performance of Big-6 Broiler White Turkeys in the Different Rearing Conditions
(2010) Sogut, B.; Kurbal, O.F.; Demirulus, H.; Inci, H.
This study was conducted to determine the effect of rearing partially outdoor and indoor conditions on growth rate and carcass yields of Big-6 heavy white turkeys. Totally 144 white toms were divided into 3 groups (Pasture-1, Pasture-2 and Control) with 6 replicates, randomly. Pature-1 (PI) and Pasture-2 (P2) had outdoor access from 42 and 49 days old till end of the trail, respectively, while control group was kept indoor. All birds consumed commercial turkey breeding feed. At the end of trial, no significant differences were observed in terms of body weight but the best one was the control group. The lower feed consume and the best feed to gain was observed in PI (3.06) and P2 (3.56) then Control group (3.73), which was significantly different (p<0.05). Outdoor access did not have significant effect on carcass weight, breast meat and legs (Thights + drumstick) but it differed the wings (p<0.05). As a result, it has been said that Big-6 heavy Turkeys have to be fed inside without outdoor access so far. According to results of present study, one may say that Big-6 white turkey could be grazed with no deleterious effect on growth performance. However, more study is needed to determine age of access to outdoor and growth performance of Big-6 white turkeys at different grazing fields. © Medwell Journals, 2010.
