Effects of Alum Treatment of Two Litter Materials on Growth Performance of Broiler Chicken
(Academic Journals, 2009) Alkis, Emine; Celen, Mehmet Fatih
The objective of this study was to evaluate the effects of aluminum sulfate (alum) amendment to 2 litter materials on broiler growth performances. 645 newly born broiler chicks were randomly allocated into 4 litter groups (control straw, control sawdust, alum treated straw and alum treated sawdust). Feed and water were provided ad libitum throughout the 42 day experimental period. Chicks were placed in floor pens at a final stocking density of 12 bird/m(2). At the end of the experiment, live weights of control straw, control sawdust, alum treated straw and alum treated sawdust groups in females were 2173.46, 2183.43, 2365.74, 2383.27 g respectively and in males were 2566.69, 2503.43, 2578.68, 2675.46 g respectively. Alum provided benefits broiler weight gain when compared to the untreated control. FCR of control straw, control sawdust, alum treated straw and alum treated sawdust groups were 1.76, 1.72, 1.86 and 1.77 respectively. Livability of control straw, control sawdust, alum treated straw and alum treated sawdust groups in females were 88.59, 90.55, 83.97 and 88.13% respectively and in males 91.73, 96.51, 90.64 and 90.79% respectively. Livability (%) was not different (P > 0.05) among treatments. The weight of breast (g), neck (g), gizzard (g), heart (g), back (g) and fat (g) did not differ among groups. There were significantly different in live weight and weight of carcass (g) among groups. Thigh (g), wing (g), liver (g) were significantly different among groups and sexes (P < 0.05).
The Effects of Broiler Breeder Age and Extra Oxygen Addition Into Incubator at High Altitude (1700 M) on Hatching Results and Subsequent Performance in Broilers
(Medwell online, 2009) Celen, Mehmet Fatih; Yildirim, Iskender; Parlat, Sinan S.; Alkis, Emine
Breeder age and oxygen concentrations from 15-21 days of incubation were tested as factors determining on hatching and subsequent performances of broiler at high altitude. Eggs produced by breeders of 31 or 55 weeks of age. All eggs from 2 breeder ages were distributed randomly into 2 hatching cabinets, which were operated at different oxygen concentrations. The 1st cabinet was oxygenated at 25%, whereas, no oxygen added to the 2nd cabinet and called control group. Fertile hatchability was affected by the Oxygen supplementation and flock age interaction. The highest fertile hatchability was obtained when the breeders were 55 weeks of age with adding oxygen but not in breeders at 31 weeks of age. The fertile hatchability was decreased at 55 weeks of age in control group. The late embryo mortality was significantly depressed in embryos from breeders at 55 weeks of age when oxygen added. Chick weights of hatch, 1st and 3rd weeks among groups were not affected by interaction between Oxygen. supplementation and flock age. Feed conversion ratio and mortality were enhanced in chicks obtained from breeders 55 weeks of age when oxygen added. It is concluded that oxygen supplement to the incubators at high altitude improves the fertile hatchability, feed conversion ratio and decreases mortality of chicks obtained from breeder of 55 weeks of age.
