E-mail: viott@ufpr.br Cystomatosis of the apocrine gland is a rare condition reported in dogs and cats. It is a non-neoplastic condition, characterized by several groups of dilated cystic sweat glands. Rarely a more widespread distribution can be observed. A captive female about 16 year-old melanic jaguar (Panthera onca) presented increased abdominal volume. Physical examination showed multiple floating nodular masses ranging from to 2 to 15cm in diameter located in the ventral abdomen. Other masses of smaller diameter (0.5-1.0cm) were present in the cervical region and in the back of the jaguar. These masses were surgically removed. Within this cyst had a odorless translucent content. Microscopically, between the mid and deep dermis there existed multiple cysts of different sizes, coated with a single layer of cuboidal cells. In some foci, there were rare papilliform projections of glandular epithelium. The cytoplasm was slightly eosinophilic with rare images of decapitation of the apex. The diagnostic of apocrine cystomatosis was performed through macroscopic and microscopic findings.

Pesquisa Veterinária Brasileira 37(9):991-994, Universidade Federal do Paraná, Setor Palotina, Jardim Dallas, Rua Pioneiro 2153, Palotina, PR 85950-000, Brazil. E-mail: viott@ufpr.br A cistomatose de glândula apócrina é uma condição rara e não-neoplásica, que tem sido relatada em cães e gatos, e caracterizada por vários grupos de glândulas sudoríparas dilatadas, cuja distribuição generalizada raramente é observada. Uma fêmea de onça-pintada melânica (Panthera onca), com idade estimada de 16 anos e mantida em cativeiro, apresentou aumento de volume abdominal. Ao exame físico foram observados vários nódulos de consistência macia e flutuante, não aderidos, com tamanho de 2 a 15cm de diâmetro, na região ventral abdominal. Outras massas de menor diâmetro (0,5-1,0cm) estavam presentes na região cervical e no dorso do animal. Estas massas foram removidas em um procedimento cirúrgico. Dentro deste cisto havia conteúdo líquido, inodoro e translúcido. Microscopicamente, observou-se entre a derme média e profunda a formação de múltiplos cistos de tamanho variável. Esses cistos eram revestidos por uma única camada de células predominantemente cubóides. Em alguns focos eram observadas raras projeções papiliformes de epitélio glandular. O citoplasma estava levemente eosinofílico e com raras imagens de decapitação do ápice. O diagnóstico de cistomatose de glândulas apócrinas foi realizado através dos achados macroscópicos e microscópicos.

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.

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: pachaly@uol.com.br This paper reports the anesthetic effects of the combination of tiletamine HCl, zolazepam HCl, and xylazine HCl in tigrinas, Leopardus tigrinus Schreber, 1775 (Fam. Felidae), submitted to semen collection by electroejaculation. Three different protocols and the individual anesthetic doses were calculated by interspecific allometric scaling, based on the usual recommendations for a 10.0 kg domestic dog: On Protocol 1 (n=10) the basis for calculation was 5.0mg/kg for tiletamine + zolazepam and 0.5mg/kg for xylazine; on Protocol 2 (n=12) 5.0mg/kg for tiletamine + zolazepam and 0.75mg/kg for xylazine; and on Protocol 3 (n=11) 5.0mg/kg for tiletamine + zolazepam and 1.0mg/kg for xylazine. The tigrinas were anesthetized on three different occasions with a minimum interval of 30 days. During 120 minutes after the drug administration cardiac and respiratory frequencies, rectal temperature, limb myorelaxation and sensitivity to deep pain were monitored. Latency period, anesthetic period, and contamination of the semen with urine were also monitored. From a total of 32 collections, 10 samples (31.2%) and 18 aliquots (0.07%) were contaminated and rejected, but this episodes were not detrimental for semen analysis and processing. A discrete increase in rectal temperature during electroejaculation caused by muscle contraction, followed by temperature decrease, was observed. Cardiac and respiratory frequency varied during the experiment, but remained within physiological standards for the species. The three tested protocols showed to be safe and effective to produce analgesia and anesthesia in L. tigrinus during semen collection by electroejaculation.
