Foluke Aderemi, Olufemi Alabi, Oluseyi Ayoola


This study was conducted to investigate the effects of garlic powder and dried pepper on performance, egg traits and serum parameters of laying chickens.

A 10 week study was carried out using 90 ISA brown layers that have laid eggs for 2 years. The diets were formulated such that diet I with 0% pepper and garlic served as the control, while diets II and III had 4g/kg of powdered garlic and dried pepper respectively. The layers were divided into 3 groups fed on these diets and replicated thrice. Data were analyzed by ANOVA using a completely randomized design.

Results showed that feed consumption, efficiency and egg weight were similar across the diets (P=0.05). There were improvements (P<0.05) in hen day production, egg albumen index and haugh unit of garlic fed layers. Egg yolk cholesterol of layers fed the garlic-supplemented diet reduced (P<0.05) compared with control diets. Serum total protein of garlic-fed layers increased (P< 0.05), while blood glucose and cholesterol levels decreased.

In conclusion garlic improved performance characteristics and may increase egg shelf life as indicated by egg quality improvement.
