ABSTRACT.- Carvalho A.L., Oliveira V., Moraes W., Cubas Z.S., Rinaldi A.R., Oliveira M.J., Almeida R.P. & Bordignon L.A.F. 2013. Comparison of methods for determination of nutrient digestibility of a dry kibble diet for ocelots. Pesquisa Veterinária Brasileira 33(Supl.1):71-74. Hospital Veterinário, Universidade Federal do Paraná, Campus Palotina, Rua Pioneiro 2153, Palotina, PR 85950-000, Brazil. E-mail: andersoncarvalho.mv@gmail.com In this experiment, methods of total fecal collection (TFC) and internal markers (acid-insoluble ash - AIA, crude fiber - CF, and acid-detergent fiber - ADF) were compared for determination of the coefficients of apparent digestibility (CAD) for dry matter (DM), crude protein (CP), ether extract (EE), nitrogen-free extracts (NFE), and gross energy (GE) of commercial feline dry kibble for ocelots (Leopardus pardalis). Six adult animals, weighing 12.45±1.37 kg, gradually received experimental kibble in their usual diet until the beginning of the experiment and were submitted to an adaptation period ten days prior to the collection period. CAD obtained by TFC, AIA, CF, and ADF were, respectively, 73.7, 76.83, 62.01, and 46.03% for dry matter; 81.9, 84.8, 75.8, and 63.8% for crude protein; 85, 86.7, 78.5, and 69.1% for ether extract; 78.52, 79.55, 69.11, and 53.04% for nitrogen-free extracts; and 80.5, 82.2, 71.4, and 58.4% for gross energy. The AIA method showed to be efficient in determining coefficients of apparent digestibility and may contribute to investigations on the digestibility of diets for wild felines. In comparison to the items of ocelot’s usual diet, the kibble used in this paper provided an adequate nutritional supply with reduced daily costs per animal.

RESUMO.- Carvalho A.L., Oliveira V., Moraes W., Cubas Z.S., Rinaldi A.R., Oliveira M.J., Almeida R.P. & Bordignon L.A.F. 2013. Comparison of methods for determination of nutrient digestibility of a dry kibble diet for ocelots.

Hospital Veterinário, Universidade Federal do Paraná, Campus Palotina, Rua Pioneiro 2153, Palotina, PR 85950-000, Brazil. E-mail: andersoncarvalho.mv@gmail.com Neste experimento foram comparados os métodos de coleta total de fezes (CT) e de indicadores internos (cinza insolúvel em ácido - CIA, fibra bruta - FB e fibra em detergente ácido - FDA) na determinação dos coeficientes de digestibilidade aparente (CDA) da matéria seca (MS), proteína bruta (PB), extrato etéreo (EE), extrativo não nitrogenado (ENN) e energia bruta (EB) de uma ração comercial de gatos-domésticos para jaguatiricas (Leopardus pardalis). Seis animais adultos com peso de 12,45 ± 1,37 kg receberam gradativamente a ração experimental na dieta habitual até o início do experimento e foram submetidos a um período de adaptação de 10 dias anteriores ao período de coleta. Os CDA obtidos pela CT, CIA, FB e FDA foram, respectivamente de 73,70; 76,83; 62,01 e 46,03% para matéria seca, 81,9; 84,8; 75,8 e 63,8% para proteína bruta, 85,0; 86,7; 78,5 e 69,1% para extrato etéreo, 78,52; 79,55; 69,11 e 53,04% para extrativo não nitrogenado e de 80,5; 82,2; 71,4 e 58,4% para energia bruta. O método de CIA mostrou-se eficiente na determinação dos coeficientes de digestibilidade aparente e pode contribuir com as investigações sobre a digestibilidade em dietas com felídeos selvagens. A ração utilizada permitiu aos animais um adequado aporte nutricional e apresentou menores custos/animal/dia em comparação aos itens que compunham a dieta habitual.

E- mail: nslazaro@ioc.fiocruz.br The presence of bacterial enteropathogens from fishes of a nutrient recycle system from a Experimental Station in Petropolis, RJ, was evaluated in 72 samples from april 2000 to july 2001 Simultaneously was collected the mud used as organic manure and poultry beds localized next to the tanks. The isolation procedures included preenrichment in Peptone Water followed by enrichment with alcaline Peptone Water (pH 8.4-8.6), and streaked onto GSP Agar for the isolation of Aeromonas spp. and Plesiomonas shigelloides. For enteropathogenic bacteria of the Enterobacteriaceae family, 1ml samples were transferred for enrichment in Rappaport- Vassiladis broth and Kauffmann Tetrathionate Broth followed by streak onto Hektoen Enteric Agar and Salmonella-Shigella Agar. Simultaneously at each visit samples of water from fish and macrophyte tanks were collected for monitoring faecal coliforms (MPN) using A1 medium. Among the 116 isolates, Aeromonas spp. were the most frequent (67.2%) with 9 species (A. veronii, biogroup sobria, A. hidrophila, A. sobria, A. trota, A. eucrenophila, A. veronii biog. veronii, A. media, A. cavia and A. jandaei), followed by Edwardsiella tarda (16.4%), Plesiomonas shigelloides (12.9%) and Salmonella spp. (3.4%). The NMP of fecal coliforms showed higher values in the fish tanks (>1800/100ml).
