E-mail: jllaus@fcav.unesp.br This study aimed to compare the normal intraocular pressure (IOP) and tear secretion, by means of applanation tonometry and the Schirmer tear test-1 (STT-1), in goats of the Saanen breed with different ages, and at different time points. Thirty six goats, free of ocular abnormalities, were grouped into three different age categories (n=12), animals with 45, 180 and 549 days of age. STT-1 and IOP measurements were carried out always at 9:00am and 7:00pm, during three consecutive days. Results were evaluated statistically (P<0.05). Regarding the time of the day, overall IOP values were significantly lower at 7:00 pm (P<0.001) in individuals with 45 days of age; whereas STT-1 values were significantly higher at 7:00pm (P=0.004) in goats with 549 days of age. Considering the sum of three days, both parameters were significantly lower in individuals with 45 days of age (P<0.001). Intraocular pressure and tear secretion values increase until 180 days of age in the Saanen breed of goats.

RESUMO.- Ribeiro A.P., Piso D.Y.T., Padua I.R.M., Silva M.L. & Laus J.L. 2010. Intraocular pressure and tear secretion in Saanen goats with different ages. [Pressão intraocular e produção lacrimal em cabras da raça Saanen com diferentes idades.] Pesquisa Veterinária Brasileira 30(9):798-802. Departamento de Clínica e Cirurgia Veterinária, Universidade Estadual Paulista, Via de acesso Professor Paulo Donato Castellane s/n, Jaboticabal, SP 14870-000, Brazil. E-mail: jllaus@fcav.unesp.br Objetivou-se comparar os valores normais de pressão intraocular (PIO) e de produção lacrimal, através de tonometria de aplanação e do teste da lágrima de Schirmer-1 (TLS-1) em cabras da raça Saanen, com diferentes idades e momentos. Trinta e seis cabras da raça Saanen, livres de afecções oculares, foram agrupadas em três categorias etárias (n=12), compreendendo animais com 45, 180 e 549 dias de idade. O TLS-1 e a PIO foram aferidos sempre às 9:00 e às 19:00, durante três dias consecutivos. Os resultados foram avaliados estatisticamente (p<0,05). Relativamente ao horário do dia, a PIO foi significativamente menor às 19:00 (p<0,001) nos animais com 45 dias de idade; os valores do TLS-1 foram significativamente maiores às 19:00 (p=0,004) nas cabras com 549 dias de idade. Considerando-se a somatória dos três dias, ambos os parâmetros foram significativamente menores nos indivíduos com 45 dias de idade (p<0,001). A pressão intraocular e a produção lacrimal em cabras da raça Saanen se elevam de forma significativa até os 180 dias de idade.

Hospital Veterinário, CSTR, Campus de Patos da Universidade Federal de Campina Grande, Patos, PB 58700-000, Brazil. E-mail: franklin.riet@pq.cnpq.br Para determinar as doenças que ocorrem no sistema nervoso de bovinos no semiárido nordestino, foi realizado um estudo retrospectivo em 411 necropsias de bovinos realizadas no Hospital Veterinário da Universidade Federal de Campina Grande, Patos, Paraíba, entre janeiro de 2000 a dezembro de 2008. Dos 411 casos analisados 139 (33,81%) apresentaram alterações clínicas do sistema nervoso e as fichas foram revisadas para determinar os principais achados referentes à epidemiologia, aos sinais clínicos e às alterações macroscópicas e microscópicas. Em 28 (20,14%) casos o diagnóstico foi inconclusivo. As principais enfermidades foram raiva (48,7% dos casos com sinais nervosos), abscessos cerebrais (7,2%) incluindo três casos de abscesso da pituitária, febre catarral maligna (6,3%), botulismo (6,3%), alterações congênitas (4,5%), traumatismo (4,5%), tuberculose (2,7%), tétano (2,7%), infecção por herpesvírus bovino-5 (2,7%), encefalomielite não supurativa (2,7%), intoxicação por Prosopis juliflora (2,7%), status spongiosus congênito de causa desconhecida (1,8%) e polioencefalomalacia (1,8%). Outras doenças diagnosticadas numa única oportunidade (0,9%) foram criptococose, listeriose, encefalite tromboembólica, linfossarcoma, tripanossomíase e babesiose por Babesia bovis.

Hospital Veterinário, CSTR, Campus de Patos da Universidade Federal de Campina Grande, Patos, PB 58700-000, Brazil. E-mail: franklin.riet@pq.cnpq.br Diseases of the nervous system of cattle in the semiarid region of northeastern Brazil were evaluated by a retrospective study of 411 cattle necropsies performed in the Veterinary Hospital of the Federal University of Campina Grande, Patos, Paraíba, from January 2000 to December 2008. Of the 411 cases analyzed, 139 (33.81%) were from cattle that presented nervous signs and the records were reviewed to determine the epidemiological, clinical, and macroscopic and histologic main features. Diagnosis was inconclusive in 28 cases (20.14%). In cases with diagnosis the main diseases were rabies (48.7% of the cases with nervous signs), brain abscesses (7.2%) including three cases of pituitary abscesses, malignant catarrhal fever (6.3%), botulism (6.3%), congenital malformations (4.5%), trauma (4.5%), tuberculosis (2.7%), tetanus (2.7%), infection by bovine hervesvirus-5 (2.7%), non-suppurative encephalomyelitis (2.7%), intoxication by Prosopis juliflora (2.7%), congenital status spongiosus of unknown etiology (1.8%), and polioencephalomalacia (1.8%). Other diseases diagnosed only once (0.9%) were cryptococcosis, listeriosis, thromboembolic encephalitis, lymphosarcoma, trypanosso-miasis, and babesiosis by Babesia bovis.

E-mail: lafranco@vet.ufg.br With the objective to investigate a possible association between foot diseases, clinical mastitis and/or metritis and predisposing factors for foot diseases, 5300 dairy cows from 80 intensive and semi-intensive farms were used. In 325 (6.13%) cows only foot disease was diagnosed, in 35 (0.66%) foot disease and clinical mastitis, in 52 (0.98%) foot disease and metritis, in 28 (0.53%) foot disease, clinical mastitis and metritis, in 128 (2.42%) only metritis, in 165 (3.11%) only clinical mastitis, and in 89 (1.68%) cows metritis and clinical mastitis. Rapid changes in the diet, high exposure time of hoof horn to slurry and wet conditions, concrete floors, use of footbaths, low frequency of claw trimming, irregular quarantine, and no attention to health aspects during acquisition of the animals were considered as major risk factors for the occurrence of those diseases. The McNemar test for dependent samples showed significant statistical differences between the occurrence of foot disease, clinical mastitis and metritis, in spite of the poor association between those diseases. It was concluded that there was no expressive relationship between foot diseases, clinical mastitis and metritis in lactent cows.
