Última Conditioning and aversion to toxic Solanum bonariense ("naranjillo") leaves in calves Ciência Rural Ruiz-Santos,Paul; Pfister,James Alan; Verdes,José Manuel. ABSTRACT: Solanum bonariense is a perennial poisonous shrub that induces cerebellar cortical degeneration when eaten by cattle. The aim of this research was to outline a protocol to induce a conditioned aversion to this plant. During the pre-conditioning period ten calves (126±12kg BW) were maintained at half of their normal energy intake with lucerne hay and water ad libitum, to stimulate consumption of S. bonariense. Every two days they were offered 100g ofS. bonariense leaves for 5 minutes. Calves began eating the target plant on day 10 and consumed all the plant material on day 12. The conditioning period began after each calf consumed the entire amount of S. bonariense for three consecutive sessions. Five animals were randomly selected for...

Brachiaria (signalgrass) is now the most widely used tropical grass genus in Central and South America. However, Brachiaria spp. can cause hepatogenous photosensitization in livestock. Steroidal saponins, specifically protodioscin, present in Brachiaria spp. may be responsible for liver injury and subsequent photosensitization. The objective of this study was to determine the effect of ensiling Brachiaria decumbens and Brachiaria brizantha or making hay from Brachiaria decumbens on the concentrations of steroidal saponin in these grasses. Brachiaria grass had no detectable levels of the saponin protodioscin after 24 days of ensiling. In addition, in Brachiaria decumbens, the concentration of the protodioscin decreased 48% over the first three days after...
