To evaluate the effect of phosphorus supplementation for goats grazing for the semiarid region, one group of 16 recently weaned Moxotó goats was supplemented with a mineral supplement containing Na, Cl, Zn, Cu, Se, Co, and P during 240 days. Another similar group was supplemented with a similar mineral supplement without P. The mean daily consumption of supplement by animal was of 7.09±2.77g and 7.67±3.14g for the groups with and without P, respectively. The mean weight gain of the P supplemented group (45.20±5.56g) was significantly higher (P<0.05) than the non-supplemented group (40.03±2.80g). The average total P in soil was 30.8mg/kg and in the pasture 0.13% in dry matter. These results demonstrate the occurrence of P deficiency in some areas of the Brazilian semiarid region.

Relata-se um surto de doença exantemática, caracterizada como varíola bovina, acometendo bovinos e seres humanos na Zona da Mata Mineira. Setenta e duas propriedades, distribuídas em 20 municípios localizados na região, foram visitadas para se levantar os aspectos clínicos e epidemiológicos da doença. Detectaram-se 1020 vacas doentes durante a investigação, quando houve queda na produção do leite associada a infecções bacterianas secundárias. Casos humanos foram registrados em 83% das propriedades visitadas. Espécimes clínicos e amostras de soro foram coletados dos animais doentes ou convalescentes. O diagnóstico de laboratório mostrou o envolvimento de um ortopoxvírus, precisamente o Vaccinia virus como agente etiológico do surto.

It was investigated an outbreak of exantemal disease in human and cattle in Zona da Mata region, Minas Gerais's State, Brazil. Seventy two farms located in 20 counties locating in this region were visited and disease pattern was studied. 1020 cows got sick in the visited herds and in 83% of them human cases occurred together with disease in animals. Drop in milk production and secondary infection were frequently observed. The disease occurred mainly from may to September. Serum and scars from sick and convalescent animals were collected and laboratory diagnostic showed that an orthopoxvirus, more precisely vaccinia virus was involved in the outbreak.
