Effects of dietary administration of yarrow extract on growth performance and blood biochemical parameters of rainbow trout (Oncorhynchus mykiss)

摘要: The present study was conducted to investigate the clinical effects and possible side of yarrow extract ( Achillea millefolium L.) as feed additive on biochemical blood parameters growth performance rainbow trout Oncorhynchus mykiss ). Fishes were treated with 0 (control), 0.1, 0.5 1% for 30 days. Plasma alanine aminotransferase (ALT), aspartate (AST), lactate dehydrogenase (LDH), alkaline phosphatase (ALP), creatine kinase (CK), peroxidase activity, total complement lysozyme glucose, protein, triglyceride cholesterol measured after 15 days treatment. There no significant changes in activity glucose levels. Total protein globulin levels significantly higher fish fed diets enriched day 30. Triglyceride decreased containing 0.5% P <0.05). LDH, CK activities having at end experiment In contrast, a increase AST, ALP observed diet, weight gain specific rate increased food conversion ratio Condition factor than control group day. conclusion, basis these results, oral administration up have not effect fishes. However, caused cytotoxicity modifications fish.
