The Effects of Alum Application To Different Bedding Materials on Litter Characteristics
(2009) Celen, M.F.; Alkis, E.
The effects of alum (A12(SO4)3•14H2O) amendment to different bedding materials (straw and sawdust) on litter properties was evaluated. The research was carried out in 2 parts of poultry house as control and treatment groups. Each part have 4 environmentaly controlled chambers. The study was conducted for 6 weeks. Litter sampels collected from poultry house at the end of study. Litter pH for the alum treated litters is lower than the control litters. The sawdust and the alum treated-sawdust litter increased content of dry matter relative to straw and the alum treared-straw litters. The alum treated-sawdust litter was higher N contents than the sawdust litter. The P contents of the alum treated sawdust was higher than the other groups. Mean total Ca, Mg andK concentrations in the straw litter were significantly affected by the alum amendment. We also, found lower total Fe and Mn concentrations in the alum treated-straw litters than in the straw litters and there were no statistical differences in total Fe and Mn between the sawdust and the alum treated sawdust. There were no statistical differences in total Zn and Cu among the litter groups. Mean total Zn and Cu concentrations in the litter were not significantly affected by the alum amendments or bedding materials. Dry matter content, pH and ammonia concentration can affect ammonia emission in poultry house. © Medwell Journals, 2009.
Effects of Elevated Oxygen Concentrations During Plateau and Pipping Stages of Incubation on Hatching Results and Some Supply Organ Weights in Pheasant (Phasianus Colchicus) Hatching Eggs at High Altitude
(Medwell Journals, 2010) Yildirim, I.; Celen, M.F.
This study deals with the effects of extra oxygen supplementation in high altitude (1700 m) on hatching traits in pheasant (Phasianus colchicus) eggs during the last 4 days of incubation. The hatching eggs were obtained from a 44 weeks old Pheasant flock. All eggs were distributed randomly into one incubator and incubated for 37.6°C and 58% RH 21 days using uniform conditions. At the start of 22nd day of incubation, the eggs were randomly distributed to two experimental hatching cabinets. The temperature and RH were changed as 37.2°C and 90-92%, in both cabinets for the last 4 days of incubation. During the last 4 days of incubation, two oxygen concentrations were added to the cabinets as 19 and 23%, separately. Fertile Hatchability (FH), Internal (IP), External (EP) pipping mortalities and Late Mortalities (LM) of embryos and some supply organ weights of chicks were recorded. The 23% oxygen treatment significantly reduced EP and LM mortalities compared to control group. Increasing oxygen level at this altitude has improved the FH in 23% oxygen treatment group compared to that resulting from 19% oxygen. At hatch, lower liver weights were obtained from 23% oxygen treatment group compared to control group. These findings revealed that fertile hatchability can be improved if oxygen levels elevated at high altitudes during plateau stage of incubation in Pheasant eggs. © Medwell Journals, 2010.
