“…Cashew apple is a rich source of carbohydrates, fibre, and antioxidants, making it a potential ingredient in poultry diets (Das;Arora, 2017;Reina et al, 2022;Akyereko et al, 2023;Van-Walraven;Stark, 2023). However, like other agro-industrial by-products, cashew apple has several limitations in its usage as a feed component, including its low nutrient density, high fibre content, and presence of anti-nutritional elements (Vergara et al, 2010;Tamiello-Rosa et al, 2019;Dakuyo et al, 2022;Akyereko et al, 2023).…”

A total of two hundred and ten one-day-old Ross 308 broiler chicks were utilized in this study to investigate the effects of incorporating Dried Cashew Apples (DCA) in the diet of broiler chickens on growth performance, total tract digestibility, and gut health. The birds were weighed and randomly allotted to seven treatment groups with three replicates, each having 10 birds. The experimental design was a (2 X 3) + 1 augmented factorial arrangement in a completely randomized design. Diet D1 (control diet) was a maize-soybean meal-based; diets D2, D3, and D4 comprised 10, 20, and 30% DCA without exogenous enzyme supplementation, whereas diets D5, D6, and D7 included 10, 20, and 30% DCA treated with exogenous enzyme. Data were collected on growth performance, total tract digestibility, and gut morphology. Collected data were analyzed using SAS (2002) and separation of means was done using Duncan’s Multiple Range Tests of the same statistical software. The difference was set at p < 0.05. The study found that birds fed diets containing 10% DCA, with or without enzyme supplementation (D2 and D5), had a significantly higher Average Daily Gain (ADG) compared to those fed the control diet (D1). The ADG of birds fed diets D3 and D6 was similar to that of birds fed the control diet (D1). However, a significant decrease in ADG was observed as the dietary inclusion level of DCA increased to 30%, as seen in birds offered diets D4 and D7. In addition, a significant linear rise (p < 0.05) in Average Daily Feed Intake (ADFI) was seen when DCA was included in the diet. In addition, birds that were given diets containing DCA showed significantly higher nutrient digestibility (p < 0.05) compared to birds that were given the control diet (D1), except for birds that were given a diet containing 30% DCA without enzyme supplementation (D4), which showed significantly lower nutrient digestibility (p < 0.05) compared to birds that were given the control diet (D1). Ultimately, birds that were given meals containing DCA exhibited a significant enhancement in GIT development compared to birds on the control diet. Based on the findings of this study, it can be concluded that including DCA in the diet of broiler chickens at a level of up to 20% does not have any detrimental effects on their performance.
