The quest for enhancing the commercialization and popularity of guinea fowl and ensuring better exploitation of the higher nutritional value it has over other poultry species has necessitated the search for feed additives that will enhance its egg laying potential. A 70 days study was carried out to investigate the laying response and egg quality attributes of guinea fowl fed diets containing vitamin E (Vit. E), Selenium (Sel.) yeast supplemented with or without L-arginine (L-arg). A total of two hundred and forty (240), twenty weeks old (average weight of 2,11+ 0,02kg), helmeted guinea fowls were allotted into 8 dietary treatment. Each treatment was replicated thrice with 10 birds each in a completely randomized design. Dietary treatments were arranged in a 4 x 2 factorial arrangement of 4 additives (no additive, Sel. yeast (0,3 mg/kg), Vit. E (30 IU/kg), Sel. yeast + Vit. E) supplemented with or without 1g/kg L-arg. Data generated on laying performance and egg quality attributes of the birds were subjected to analysis of variance (ANOVA) using the general linear model of statistical analysis system. Supplementation of diet with L-arg improved (P |
