RESUMO:
The present study was conducted to determine the effects of the
inclusion of macauba cake, from biodiesel processing, on profile of
rumen protozoa of Santa Ines lambs. Twenty-four lambs were randomized in
block design supplemented with macauba cake at 0, 100, 200, and 300
g/kg of dry weight of the diet. Concentrations of small, medium, and
large protozoa had quadratic relationships with inclusion of macauba
cake, with maximum protozoa occurring at 100 g/kg. High genus diversity
occurred in rumen fluid of lambs that did not feed macauba cake,
comprising 13 protozoa genera. However, only the genera Isotricha, Charonina, Entodinium, Diplodinium, Eodinium, Diploplastron, and Polyplastron
were detected in lambs fed 300 g/kg macauba cake, indicating that these
protozoa were resistant to the effects of the cake. Addition of macauba
cake levels greater than 100 g/kg show antiprotozoal effect in the
rumen.VEJA ARTIGO COMPLETO AQUI.
