Nitrogened metabolites in golden hamster fed with proteic diets based on Eisenia spp. meal

Content of total protein (PT), albumin (Alb), globulins (Glb), urea (U), uric acid (AU), creatinine (Ct) and transaminase levels (oxalacetic-glutamic (TGO) and piruvic-glutamic (TGP)) was evaluated in the blood plasm of golden hamster (Mesocrisetus auratus L.), fed diets (crude protein; PB= 13.5- 19.6%) with red worm (HL) (Eisenia spp.) meal and two conventional feeds (Conejarina®; PB= 11.4% and Ratarina®; PB= 21.1%). The PT, Alb, Glb and Ct concentration oscillated among 5-6, 2- 3, 2-3 g/dL y 0,3-0,4 mg/dL, respectively, no significant differences among the treatments in the assay were observed (p>0.05). In the assay the U and AU content fluctuated between 23-101 y 3-9 mg/dL, respectively; according to the PB level, HL inclusion and measurement time. The transaminase levels were high and variables during the second week of assay, according to the proteic level diets (TGO: 101-699 y TGP: 54-890 UI/ L). The seric PT, Glb, Alb and Ct content were independent of PB diets and HL proportion, while the U (R²= 0.509*), TGO (R²= 0.661**) and TGP (R²= 0.524*) level were related with proteic level of diets, and the U (R²= 0.502*) and AU (R²= 0.531*) contents with the HL inclusion. The HL addition in 24, 27 and 30% for making formulated proteic diets to M. auratus cause significant variation in the normal values of U, AU and transaminases.
