  • Congenital $Neospora$ $caninum$ infection was diagnosed in two Saanen goat kids from two distinct herds with a history of abortion and weak newborn goat kids in the Southern region of the State of Minas Gerais, Brazil. The first kid was weak at birth, had difficulty to rise and was unable to nurse. Gross lesions of porencephaly and hydrocephalus ex vacuo were seen. Multifocal necrosis, gliosis and non-supurative encephalitis were observed in the brain. Several parasitic cysts with a thick wall that reacted strongly only with polyclonal antiserum to $Neospora$ $caninum$ were seen in the cerebral cortex, brain stem and cerebellum. The second kid was born from a $Neospora$ $caninum$ seropositive mother that aborted in the last pregnancy. It was born without clinical signs. The diagnosis of neosporosis was based on antibody titer of 1:800 to $N.$ $caninum$ by indirect fluorescence antibody test obtained from blood collected before the goat kid ingested the colostrum and $Neospora$ $caninum$ DNA was detected by polymerase chain reaction and sequenced from placenta. This is the first report of neosporosis in goats in the southeast region of Brazil.

  • Twelve newborn goat kids born of philippine does (3.5 and 5 years old) were used in this study. Four mother (candidate) doe goats were randomly allocated to each group. The mother does were infected orally with three levels (0, 15,000 and 30,000 larvae) of infective Haemonchus contortus larvae. Before infection all animals were housed in individual pens with concrete floors. They were provided with a uniform management. Estrus of does were synchronized using PGF2 alpha. All the animals were bred naturally by the same buck. Baby goat born of infected mother goats were divided into three groups. $T_1$, $T_2$ and $T_3$), respectively, from mother treatment groups. Birth weight and growth of goat kids born from H. contortus infected mother goats were determined. Birth weights of kids of $T_1$, $T_2$ and $T_3$ were 1.9, 1.5 and 1.2 kg, respectively. No significant (p > 0.05) differences in birth weight of kids for the 3 treatment groups were found. However, significant (p < 0.05) effects of stomach worm infection and duration of infection on liveweight gain of kids were observed. After second and third week of birth, respectively, the kids of groups 3 and 2 registered lover liveweight gains than the kids in control group. However, no significant (p > 0.05) difference in liveweight gain was found between the kids of infected mother does. Fecal egg counts of the infected mother does showed patent infections which also indicated by postmortem worm counts. However, no worm egg was found in the feces of the test kids.
