Resumen:
The aim of this study was to evaluate the effect of intraruminal boluses
with sulfamethazine (SM) and selenium (Se) on goat kids naturally
infected with Eimeria. Twenty goat kids were selected with an average
body weight (BW) of 13.7 kg. They were grouped as follows (n = 5 animals
per group). BC: dosed with boluses without drugs; BSM: dosed with
boluses containing 4 g of SM; BSe: dosed with boluses containing 90 mg
of Se; BSMSe: dosed with boluses with 4 g of SM + 90 mg of Se. All
animals showed the presence of the boluses at 10 d after dosing by
radiography. DMI/BW at the beginning of the experiment was low: 0.76%
in BC and 0.86% in the dosed groups. At the end of the experiment there
was an increase: 1.36% in BC and 1.54% in the dosed groups (P > 0.05).
BSMSe had the lowest percentage of Eimeria spp (P < 0.05). There were
differences between the Eimeria species found before and after the
treatments. It was observed that BSM and BSMSe decreased the number of
oocysts from 7 to 28 d (P < 0.05). BSMSe had the highest content of
blood SM and Se (P < 0.05). The histological alterations were loss of
the epithelium and villous atrophy.
