Resumo: | Two trials were conducted: (1) to determine the chemical composition, digestibility of nutrients and energy of cashew nut meal (CNM); and (2) to evaluate the effects of increasing its levels (0, 5, 10, 15, 20 and 25%) in diets for growing rabbits on performance, carcass characteristics and economic evaluation. The digestibility assay utilized 24 rabbits (55 days of age), distributed in a completely randomized design with two treatments and 12 repetitions, with one reference and another test feed composed of 70% basal diet and 30% CNM. The digestibility of dry matter, crude protein and gross energy from CNM were, respectively, 76.61, 61.71 and 56.53%. The digestible dry matter, digestible protein and digestible energy were, respectively, 74.28, 16.97 and 3,549 kcal/kg. The performance assay utilized 120 rabbits, with an average of 45 days of age and weight 1090 ± 151g, distributed in a completely randomized design with six treatments and 10 repetitions with two rabbits of the same sex per cage. The inclusion of CNM above 5% promoted a linear reduction in feed intake and improved feed conversion, without affecting weight gain and carcass characteristics to the 20% level of inclusion. There was also a linear reduction in feed cost per kilogram of weight gain and linear improvement in rates of economic efficiency and cost index up to 25% CNM inclusion. Based on these findings – and to not hurt performance – it is recommended to include up to 20% CNM in rabbits' diet.Keywords: alternative feedstuff, economic analysis, Oryctolagus cuniculus, productive yield. |

O ensaio de digestibilidade utilizou 24 coelhos (55 dias de idade), distribuídos em delineamento inteiramente casualizado, com dois tratamentos e 12 repetições, sendo uma ração referência e outra ração teste composta por 70% de dieta basal e 30% de FCC. A digestibilidade da matéria seca, proteína bruta e energia bruta do FCC foram, respectivamente, 76,61; 61,71 e 56,53%. A matéria seca digestível, a proteína digestível e a energia digestível foram, respectivamente, 74,28; 16,97 e 3,549 kcal / kg. O ensaio de desempenho utilizou 120 coelhos, com média de 45 dias de idade e peso de 1090 ± 151g, distribuídos em delineamento inteiramente casualizado, com seis tratamentos e 10 repetições com dois coelhos do mesmo sexo por gaiola. A inclusão de FCC acima de 5% promoveu uma redução linear no consumo de ração e melhor conversão alimentar, sem afetar as características de ganho de peso e carcaça para o nível de inclusão de 20%. Também foi observada redução linear no custo de alimentação por quilograma de ganho de peso e melhora linear nas taxas de eficiência econômica e índice de custos até 25% de inclusão do FCC. Com base nesses resultados - e para não prejudicar o desempenho - é recomendável incluir até 20% de FCC na dieta de coelhos.Palavras-chave: alimento alternativo, análise econômica, Oryctolagus cuniculus, rendimento produtivo.Universidade Federal de Goiás2020-09-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/61927Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 21 (2020): Continuous publicationCiência Animal Brasileira / Brazilian Animal Science; v. 21 (2020): Publicação contínua1809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporenghttps://revistas.ufg.br/vet/article/view/61927/35408https://revistas.ufg.br/vet/article/view/61927/35409https://revistas.ufg.br/vet/article/view/61927/35410https://revistas.ufg.br/vet/article/view/61927/35411Copyright (c) 2020 Ciência Animal Brasileirainfo:eu-repo/semantics/openAccessGomes, Thalles RibeiroFreitas, Ednardo RodriguesWatanabe, Pedro HenriqueSousa, Amanda da RochaFerreira, Ana Carolina SampaioTavares, Leila Maria de Sousa2023-03-23T18:46:38Zoai:ojs.revistas.ufg.br:article/61927Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:56:26.103719Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
