  The aim of this experiment was to determine blood profile (hemoglobin, hematocrit, red blood cells, white blood cells), differential leucocytes count (neutrophils, lymphocytes, monocytes, eosinophils) and chromium in blood of lactating cows supplemented with organic chromium (Cr) and Ganoderma lucidum in ration. Fifteen lactating cows grouped and allocated in the five treatments in randomize block design, were fed a basal diet composed of 60% grass and 40% concentrate. Supplementation on basal diet as treatment were: A = basal diet (control), B = 3 ppm inorganic Cr in CrCl3.6H2O, C= 3 ppm organic Cr (fermentation product with Ganoderma lucidum), D = Ganoderma lucidum (5 g 50 kg-1 live weight) and E = Organic Cr+Ganoderma lucidum. Blood profile, differentiation of leucocytes and chromium in blood were investigated. The result showed that there were no significant differences on blood profile (p>0.05). Total leucocytes count was 7120±1.44 cell/μl in treatment E to 9270±2.32 cell/μl in control. Also, organic Cr and Ganoderma lucidum supplementation had no significant effect on differential leucocytes counts and chromium in blood (p>0.05). It can be concluded that blood profile, differential leucocytes count and chromium in blood of lactating cows have not been affected by supplementing organic chromium and Ganoderma lucidum in ration.

  Background and Objective: Bone meal and bone char produced from inedible cow bones could be an alternative renewable and low-cost dietary Phosphorous (P) source in poultry diets. This study aimed to evaluate the physical characteristics, mineral composition and nutritive value of bone meal and bone char meal produced from inedible cow bones derived from different body parts of the animal. Materials and Methods: A field survey was carried out to collect data on inedible bones taken from 30 slaughtered cows at sites involved in three meat processing steps: Slaughter house, local meat shops and beef offal processors. Samples of inedible bones grouped into three body parts: Head, ribs and legs were collected and processed into bone meal and bone char meal by soaking in lime water and open-air burning, respectively. The nutritive values of the bone meals were also evaluated by mixing 3% bone meal and bone char with a basal diet that was fed to 150 laying quails. Parameters measured included: Inedible bone weight, percentage of meal yield, content of crude ash and minerals (Ca, P, Fe, Zn, Mn and Cu), physical properties and particle size distribution, egg production, egg shell quality, digestibility and tibia bone mass and mineralization. Results: Present study showed that on average inedible bones represented 13.8 kg/animal or 3.4% b.wt., that could be used to produce bone meal. Percentage of meal yield for bone meal (91.4%) was significantly higher (p<0.01) than bone char processed by open-air burning (67.3%). However, crude ash, Ca and P content of bone char meal were significantly higher (p<0.05) than that for bone meal. Bone char produced a higher response angle due to a higher percentage of small-sized particles (p<0.05). There was no significant effect of bone origin (i.e., head, rib and leg) on meal yields, mineral composition or particle sizes. Supplementation of diets with bone char yielded better quail egg shell quality, mineral digestibility and bone weight than that for bone meal. Conclusion: Production of bone char meal by open-air burning gave lower meal yield but higher essential mineral concentrations and better nutritive values than that of bone meal.
