Effect of Feeding Chemically and Biologically Treated Barley Straw on Some Hematological and Serum Biochemical Parameters of Karadi Lambs

Aims: This study was conducted to evaluate the effect of feeding untreated, urea and fungal (Pleurotus ostreatus, Po) treated barley straw on some blood profiles of Karadi lambs.
Place and Duration of Study: Department of Animal Production, over the periods 1-2-2010 to 1-4-2010.
Methodology: The measured hematological parameters were; mean corpuscular hemoglobin concentration (MCHC), Mean corpuscular hemoglobin (MCH) and mean corpuscular volume (MCV) were calculated from red blood cell (RBC), white blood cell (WBC), hemoglobin (Hb), packed cell volume (PCV) and measured serum biochemical parameters were albumin, globulin, creatinine, high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglycerides and uric acid and alkaline phosphatase (ALP).
Results: The results revealed that red and white cells , packed cell volume, hemoglobin and mean corpuscular hemoglobin were significantly higher in lambs fed fungal treated barley straw (FTS) than those fed urea treated barely straw (UTS) or untrated barley straw (US). Mean corpuscular hemoglobin concentration was (32.61g/dl) higher in lambs fed FTS and UTS (32.40g/dl) than those lambs fed US (32.09 g/dl). Lambs fed UTS and FTS had significantly increased serum albumin as compared with those lambs fed US; whereas, globulin concentration was significantly higher in lambs fed FTS than those lambs fed UTS and US. While, lambs fed FTS and UTS showed significant reduction in the uric acid and low-density lipoprotein as compared with those fed US. Lambs fed FTS had significantly reduced alkaline phosphatase as compared with those fed UTS and US.
Conclusion: It can be concluded that lambs fed FTS showed a good health as compared with those fed US or UTS.
