ABSTRACT
Effects of dietary Agaricus bisporus mixture or stalk or cap on growth performance, carcass components and some meat quality parameters, mesophilic aerobic bacterial counts, and intestinal histomorphology in broiler chickens were investigated. Two hundred and forty one-day-old male Ross 308 broiler chickens were divided into 4 experimental groups with 4 replicates, each including 15 birds. Chickens were fed with basal diet (C), mushroom mixture (MM, 10 g stalk+10 g cap/kg diet), mushroom stalk (MS, 20 g/kg diet) and mushroom cap (MC, 20 g/kg diet). Feed conversion ratio (FCR) was improved (P < 0.01) by dietary MS while feed intake (FI) decreased (P < 0.01) in all treatment groups compared to control. However, body weight gain (BWG) was decreased (P < 0.01) by MC inclusion. Mushroom supplemented groups had higher (P < 0.05) mesophilic aerobic bacteria in the cecum. MS inclusion increased villus height to crypt depth ratio in the jejunum (P < 0.01) and villus height in the ileum (P < 0.01) and jejunum (P < 0.05). MC increased (P < 0.01) crypt depth in the jejunum. There were no statistical differences among groups for carcass components (P > 0.05). The L* values were decreased (P < 0.01) in thigh meat but increased (P < 0.01) in breast meat by mushroom inclusion. The a* values were decreased (P < 0.01) and b* values were increased (P < 0.05) in both thigh and breast meat with mushroom addition to diet. The obtained results indicated that A. bisporus stalk meal at an inclusion level of 20 g/kg of diet had favourable effects on growth performance with higher feed efficiency, improved intestinal morphology with higher villus height and increased meat quality of broiler chickens.
RESUMO
Foram investigados os efeitos da mistura dietética de Agaricus bisporus ou talo ou tampa sobre o desempenho de crescimento, componentes da carcaça e alguns parâmetros de qualidade da carne, contagens de bactérias aeróbias mesofílicas e histomorfologia intestinal em frangos de corte. Duzentos e quarenta frangos de corte Ross 308 de um dia de idade foram divididos em quatro grupos experimentais com quatro repetições, cada um incluindo 15 aves. Galinhas alimentadas com dieta basal (C), mistura de cogumelos (MM, 10 g caule + 10 g cap / kg de dieta), caule de cogumelo (MS, 20 g / kg dieta) e cogumelo (MC, 20 g / kg dieta). A taxa de conversão alimentar (FCR) foi melhorada (P < 0.01) por MS dietético enquanto o consumo de ração (FI) diminuiu (P < 0.01) em todos os grupos de tratamento em comparação com o controle. No entanto, o ganho de peso corporal (BWG) foi diminuído (P < 0.01) pela inclusão de MC. Os grupos suplementados com cogumelos apresentaram maiores (P < 0.05) bactérias aeróbias mesofílicas no ceco. A inclusão de MS aumentou a proporção entre a largura das vilosidades e a profundidade da cripta no jejuno (P < 0.01) e o comprimento das vilosidades no íleo (P < 0.01) e jejuno (P < 0.05). MC aumentou (P < 0.01) a profundidade de cripta no jejuno. Não houve diferença estatística entre os grupos nos componentes da carcaça (P > 0.05). Os valores L * diminuíram (P < 0.01) na carne da coxa, mas aumentaram (P < 0.01) na carne de peito com a inclusão de cogumelos. Os valores de a* diminuíram (P < 0.01) e os valores de b* aumentaram (P < 0.05) em ambas as coxas e peitos pela adição de cogumelos à dieta. Os resultados obtidos indicaram que a farinha de colmo de A. bisporus com um nível de inclusão de 20 g / kg de dieta teve efeitos favoráveis no desempenho do crescimento com maior eficiência alimentar, melhorou a morfologia intestinal com maior comprimento de vilosidade e aumentou a qualidade da carne de frangos de corte.
