A totally of 120 commercial hens (28 weeks of age) were used in this experiment. There was a control and four treatment groups, each containing 24 hens. The experimental period lasted 16 weeks. It was concluded that feed efficiency, egg breaking strength, egg shell thickness and blood cholesterol were increased, while yolk cholesterol was significantly (p<0.01) decreased by the addition of niacin to the rations. There were no statistically significant differences among groups in terms of feed consumption and egg weight. Body weight was influenced negatively UR - https://dergipark.org.tr/tr/pub/lahaed/article/465021 L1 - https://dergipark.org.tr/tr/download/article-file/544081 ER -
