| One hundred 6- to 12-month-old Nelore calves were allotted into control group (G1; 50 healthy calves) and photosensitization group (G2; n= 50). Blood samples were collected 12 to 24 hours after the onset of dermatitis (M1), and 15 to 30 days after that (M2), at time of resolution of clinical signs. Serum protein electrophoresis was performed by means of sodium dodecyl sulphate-polyacrylamide gel electrophoresis. Eighteen serum proteins with molecular weights ranging from 16,000 to 189,000 daltons (Da) were identified in all calves. In M1 and M2 serum concentrations of proteins with molecular weights of 115,000Da (ceruloplasmin), 61,000Da (a1-antitrypsin), 45,000Da (haptoglobin), and 40,000Da (acid glycoprotein) were significantly increased in calves.

| 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... |
