Birds were assigned randomly to the groups, each of which consisted of 20 birds (4 replicate cages each containing 5 birds). The experiment w...

During the past five years we have developed three emission calorimeters (EC) that can be used to evaluate mass generation and utilization of gasses. We have tested various treatments that significantly reduced ammonia generation by laying hen manure (Harrison and Koelkebeck, 2002; 2003).

This study was to investigate the relationship between chick weight in growing period and laying performance of Korean native chicken (KNC) breeders. We measured body weights 1,384 KNC breeders at 1-140 days age two-week intervals. The first egg laying, hen-day hen-housed production, were investigated. Correlation coefficients production traits analyzed. results showed that correlation signific...

An experiment was conducted to elucidate the effects of turmeric powder supplementation on egg production performance of old laying hens (80 weeks of age). There were 40 hens of Hysex Brown strain used in the study. They were caged individually, and randomly divided into 4 treatment groups of diet containing 0 (control), 1, 2 and 4 % oven dried turmeric powder for 3 periods of 4 weeks; Egg prod...

OBJECTIVE An experiment was conducted to determine the effect of superdosing phytase on productive performance and egg quality in laying hens. METHODS A total of 200 42-wk-old Hy-Line Brown laying hens were allotted into 1 of 5 dietary treatments with 5 replicates consisting of 8 hens per replicate. The positive control (PC) and negative control diets (NC) were prepared based on the recommend...
