ResumoForam estimados, neste estudo, parâmetros relacionados à dinâmica populacional canina no Município de Ibiúna, Estado de São Paulo, para animais domiciliados, recolhidos e eutanasiados, no período de 1998 a 2002. Os dados foram obtidos a partir de fichas de cães recolhidos e eutanasiados junto ao Departamento de Zoonoses do município e também através de censos da população canina domiciliada, com levantamentos feitos casa a casa, durante as campanhas anti-rábicas. Foi observado um aumento progressivo tanto do número de cães recolhidos quanto do número de cães eutanasiados. Os valores para a razão habitante/cão média no período foram 3,16:1, 7,67:1, e 3,91:1 para a zona rural, urbana e o município todo, respectivamente, com predominância de cães machos (70,10%) e sem raça definida (80,71%), na população canina domiciliada. O crescimento anual médio da população canina domiciliada foi de 16,69%, e a maioria dos cães encontrava-se na zona rural (82,93%). A eutanásia e o recolhimento de cães não se mostraram efetivos, nos moldes em que foram aplicados, como mecanismos de controle populacional canino em Ibiúna. Os parâmetros da população canina estimados neste estudo servirão de auxílio para a elaboração de programas de controle tanto da população canina quanto de zoonoses, neste município. Os resultados observados chamam a atenção para aspectos relacionados à posse responsável, e sobre a importância do papel dos proprietários de animais na solução do problema do abandono de cães.
Animals receiving sucrose saline alone and sucrose saline with homeopathy had less weight loss than control (p=0.017, p=0.0001 respectively). There was no statistical difference in relation to overall incidence of diarrhea or food consumption. These data suggest that the supplementation with sucrose saline with added homeopathic medicine in the first seven days post-weaning may be an useful option to reduce weight loss in weaned piglets.
The aim of this research was to evaluate the efficacy of zinc gluconate associated with dimethyl sulphoxide (DMSO) for chemical neutering in canine males. Fifteen sexually mature male dogs were divided in two groups, named control and treated. An injection was administered to both testicles, at a concentration of 26.2 mg zinc gluconate per ml and 0.5% DMSO in the treated group (11 dogs). The control group was given injections of saline solution (four dogs). Clinical examination and blood collection for a haemogram were done both before and after drug injection. There were 12 spermograms performed to analyse sperm motility, sperm vigour, ejaculate volume, testicle size, pathology and sperm concentrations. Libido was also measured. An ultrasound examination and histopathology were performed at the end of the experiment. Dogs' libido after chemical injection was reduced by over 50%. The spermogram analysis showed final mean results of 14.54% for sperm motility, 0.72 of sperm vigour and 37,150 per million spermatozoa per millilitre, values considered below the necessary levels at which fertilization can occur. Ultrasound and histopathology analyses of testicles for the treated group revealed more intense injuries when compared with the control group, with compromised testicular parenchyma and a decrease of germ cell number leading to total atrophy, indicating that the treatment reduced the fertilizing potential of male dogs, promoting a possible subfertile status.
A survey in Ibiúna, Sao Paulo, Brazil, of caregivers (owners) who adopted shelter dogs assessed length of ownership, proportion of male and female dogs adopted, and owners' characteristics. It addressed breeding, neutering, vaccination, and veterinary care. It used no testing to provide a good "match" between dog and future owner. Of adopted dogs, 58% were male. Only 36% of owners were located. Mean ownership length was 14.8 months (95% confidence interval = 12.4 to 17.2 months), estimated through a survival analysis method. Of adopted dogs, 40.9% lived with their owners; 34.9% had died (some had lived on the streets); 15.0% were donated; 4.3% ran away; 3.2% were returned to the city shelter. Of interviewees, 57% reported no difficulties with the adoption; 23.1% cited the animal's illness and death as the main difficulty. For contraception, 87 owners (46.7%) chained dogs to prevent contact with other animals; 56.5% were against neutering. Reasons given were compassion (58.1%), unnecessary procedure (11.4%), cost (9.5%), and behavior change (4.8%). This research motivated a design for Ibiúna shelter dog adoption to improve the proportion of successful adoptions.
RESUMO: O objetivo do trabalho foi determinar a prevalência de leptospirose e brucelose por Brucella canis e determinar os fatores de risco associados com a positividade em cães da Estância Turística de Ibiúna, estado de São Paulo, Brasil. Foram examinados 570 animais distribuídos em 4 regiões nos 48 bairros do município, no período de setembro de 2007 a março de 2008. O diagnóstico sorológico da leptospirose foi efetuado com o teste de soroaglutinação microscópica (SAM), e para o diagnóstico de brucelose foi realizado hemocultivo. Dos 570 animais examinados, 187 (32,8%; IC95% 28,9 - 36,8) foram soropositivos para leptospirose, com predomínio de reações para os sorovares Pyrogenes, Autumnalis e Canicola, e 6 (1,05%; IC95% 0,4 - 2,2) foram positivos para brucelose. A variável atividade sexual (OR = 1,73) foi identificada como fator de risco associado à positividade para leptospirose, e o manejo do tipo solto foi considerado fator de risco tanto para leptospirose (OR = 1,96) quanto para brucelose (OR = 10,85). Conclui-se que a leptospirose e a brucelose estão presentes em cães da Estância Turística de Ibiúna, São Paulo, e que a atividade sexual e o acesso irrestrito à rua são condições associadas com a prevalência das infecções.
