Nutritional evaluation of almond cashew nut by-products in diets for slow-growing broiler chickens / Avaliação nutricional dos subprodutos da amêndoa da castanha de caju em dietas para frangos de crescimento lento

The aim of this study was to determine the apparent digestibility and energy value of almond cashew nut by-products for slow-growing broiler chickens. Seventy-six chickens (males and females) were allocated in a completely randomized design to four treatments: a control diet and the same diet in which the conventional ingredients were replaced with 30% (kg/kg) almond cashew nut film, almond cashew nut meal or almond cashew nut mass. The animals were housed in individual cages adapted for excreta collection. The apparent digestibility coefficients of film, full meal and almond mass were, respectively, 81.3, 87.3 and 86.2% for dry matter; 32.1, 71.2 and 56.7% for crude protein (CP); 82.7, 92.6 and 92.8% for ether extract; 10.9, 29.9 and 34.7% for neutral detergent fiber; 7.7, 17.9 and 19.6% for acid detergent fiber; 41.9, 57.2 and 66.7% for coefficient of gross energy metabolism (CGEM); 1,189, 2,648 and 3,719 kcal/kg for apparent metabolizable energy (AME); 8.1, 19.9 and 12.9% for digestible protein, and 3.9, 15.2 and 6.3% for mineral matter (MM). The CP and MM apparent digestibility coefficients of full meal were higher than those of film and almond cashew nut mass, while the latter exhibited higher apparent digestibility of fiber, CGEM and AME compared to the other by-products. The inclusion of almond cashew nut by-products in diets for slow-growing broiler chickens results in lower nutrient digestibility, except for ether extract, neutral detergent fiber and AME, in diets containing 30% almond cashew nut mass.

Objetivou-se determinar a digestibilidade aparente e o valor energético dos subprodutosda amêndoa da castanha de caju para aves de crescimento lento. Setenta e seis aves (machos efêmeas) foram distribuídas em delineamento inteiramente casualizado com 4 tratamentos: umadieta controle a partir da qual houve a inclusão de 30% (kg/kg) da película, farelo integral oumassa da amêndoa da castanha de caju. As aves foram alojadas em gaiolas individuais adaptadaspara coleta total de excreta. O coeficiente de digestibilidade aparente da película, farelo integrale massa da amêndoa foram 81,3, 87,3 e 86,2% para matéria seca; 32,1, 71,2 e 56,7% para proteínabruta (PB); 82,7, 92,6 e 92,8% para extrato etéreo; 10,9, 29,9 e 34,7% para fibra em detergenteneutro; 7,7, 17,9 e 19,6% para fibra em detergente ácido; 41,9, 57,2 e 66,7% para o coeficiente demetabolização de energia bruta (CMEB); 1189, 2648 e 3719 kcal/kg para energia metabolizávelaparente (EMA); 8,1; 19,9 e 12,9% para proteína digestível e disponibilidade de 3,9; 15,2 e 6,3%para matéria mineral (MM).

Valor nutritivo do resíduo de caju desidratado associado a diferentes concentrados / Nutritional value of byproduct cashew dehydrated associated with different feed

coconut meal, a byproduct of agribusiness, film nut

The objective was to evaluate intake and digestibility of diets based waste cashew with different concentrates in the diet of sheep. We used 24 sheep of the Morada Nova, female, 8 months old and weight 20 kg, distributed in a completely randomized design with four treatments and six repetitions. Evaluated the intake in g / animal / day,% LW g/w0, 75 and digestibility of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE) and neutral detergent fiber (NDF) of diets containing residue associated with dehydrated cashew concentrate containing wheat (feed wheat), soy (soy diet), coco (coconut diet) and film nut (nut diet). There were significant effects (P 0.05). There were no differences (P> 0.05) for DM, EE, CP and NDF. The coconut diet showed the lowest values for the intake and digestibility of nutrients.

There were significant effects (P <0.05) for DM, OM, CP and EE in all units of expression evaluated. There was no significant effect on NDF intake in g / day,% BW and g / UTM (P> 0.05). There were no differences (P> 0.05) for DM, EE, CP and NDF. The coconut diet showed the lowest values for the intake and digestibility of nutrients.(AU)
