Background: previous studies have shown that fenugreek seed given at 6 g/hen/d in an attempt to reduce yolk cholesterol tended to reduce laying performance and that autoclaving and pre-germination improved its in vitro nutritional values. Objective: to evaluate the effect of dietary addition of unprocessed (UPFS), autoclaved (AFS) or pre-germinated (PGFS) fenugreek seeds on laying hens’ performance, egg physical characteristics and chemical composition. Methods: forty-eight 31 week-old Novogen white laying hens were divided into four groups and given 100 g/hen/d of a basal diet containing 0 (control) or 5.7 g of UPFS, AFS, or PGFS during nine weeks. Repeated and non-repeated data were analyzed using the Mixed and GLM procedures, respectively. Results: diet, week on diet and their interaction affected consumption (p 0.05) by week on diet but was reduced (p 0.05) by dietary treatment or by week on diet. Egg, yolk, albumen and shell weights were affected (p 0,05) por la semana en las dietas, sin embargo, fue reducida (p 0,05) ni por la dieta ni por la semana en la dieta. Los pesos del huevo, de la yema, de la albumina y de la cascara fueron afectados (p 0,05) por semana na dieta, mas foi reduzida (p 0,05) nem pela dieta nem pela semana na dieta. Os pesos do ovo, da gema, da albumina e da casca foram afetados (p 0,05) o conteudo de proteina bruta total dos ovos, dos lipidios, triglicerides nem do conteudo de colesterol da gema. Conclusao: sementes de feno-grego nao tratadas reduziu a taxa de postura e a producao diaria de massa de ovos, mas estes efeitos foram removidos pela autoclavagem e pre-germinacao. Sao necessarias novas investigacoes para avaliar o impacto da suplementacao alimentar sobre a semente de feno-grego no perfil de acidos graxos e peroxidacao lipidica. Palavras chave: colesterol, cor da gema, qualidade do ovo, triglicerideos.
