The present study was conducted to evaluate whether dietary ferula (Ferula elaeochytris) root powder would affect laying performance, egg quality, egg cholesterol level and plasma glucose, cholesterol,triglycerides and calcium levels of Nick Brown layers. Thirty four weeks old laying hens were divided into 4 treatment groups of similar mean weight, comprising 18 birds each. The birds were fed standard layer diet having 177.6 g crude protein, 36 g calcium and 2,800 Kcal ME in each kg. Treatment birds were fed on their own diets made by 0, 2, 4 or 8 g dietary Ferula root powder as supplement to each kg standard layer diet for 8 weeks. Birds housed in individual cages were employed a 16:8 hours light:dark photoperiod. Feed and water were given ad libitum. Laying performance was determined by recording feed intake, egg weight, egg production daily; egg quality, egg cholesterol weekly and blood parameters (glucose, cholesterol, triglyceride and calcium level) biweekly. The results showed that dietary supplemental ferula root powder did not have any significant (P>0.05) effects on body weight, feed intake, egg yield (hen-day production), egg mass, egg weight and feed conversion ratio,. However, Ferula root powder improved egg shape index (P0.05) without causing any toxicity incidence and symptoms in layers with respect to health status, voluntarily feed intake and egg production, suggesting that ferula root powder, at least, could be used in layer diet to produce egg with lower cholesterol content and better shape index. |
