| An epidemiological investigation was conducted on mixed farms in Tororo and Soroti districts of Uganda from January to February 2000 to determine the cause of reported persistent mortality of cattle. Blood and faecal examination of 98 cattle comprised of 33 Friesians, 58 Zebu and 7 Sahiwal was undertaken. Results revealed 7 (7.1%) cattle had trypanosome infection, mainly due to Trypanosoma vivax and T. brucei, 17 (17.3%) had Fasciola infection, 28 (28.6%) had gastrointestinal nematode infection, 33 (33.7%) had Theileria parva infection and 13 (13.3%) had Anaplasma marginale infection. Mixed infections were detected in 24.5%, 30%, 20.6% and 43% of all cattle, Friesians, Zebu and Sahiwal respectively. Anaemia (PCV<25) was detected in 21%, 24%, 19% and 14%... |

| O presente trabalho foi realizado com dados de 131 vacas mestiças Holandês-Zebu-Gir do Sistema de Produção introduzido em 1977 no CNPGL da EMBRAPA, Coronel Pacheco, MG. As informações foram obtidas das fichas zootécnicas individuais, no período de 1977 a 1987. Estudaram-se os efeitos de fatores fisiológicos e de meio que afetam o intervalo de partos. As estimativas de média, do erro-padrão e o respectivo coeficiente de variação, de 311 intervalos de partos, ocorridos no Sistema de Produção, foram de 13,3 ± 0,3 meses e 16,9%. O ano de parto influenciou (P < 0,01) a duração dos intervalos de partos. O grupo genético dos animais, dentro de local de nascimento, teve efeito significativo sobre a característica estudada (P < 0,05). Os animais 1/2 H-Z,... |

| A study was carried out to assess the effect of mixed infection of Trypanosoma vivax and Fasciola spp. in an intensively managed dairy farm. Twenty lactating Friesian cows were screened, 25% (5/20) had concurrent infections of T. vivax and Fasciola spp., while 20% (4/20) had mixed infections of T. vivax and strongyle infection, 15% (3/20) had mixed infections of Theileria mutans and strongyle infection. Only 10% (2/20) has single infection of T. vivax and T. mutans respectively. Anemia, submandibular edema, reduce milk production emaciation and epiphora are the major clinical signs presented by the animals. |
