Milk Production and Some Blood Metabolites of Egyptian Buffaloe Cows as Affected by Chromium Methionine Supplementation
The experiment was conducted to study the effect of Chromium supplementation on performance and blood serum biochemistry of lactating buffaloe cows.Therefore,thirty lactating buffaloes (aged 3-6 years and aver.B.Wt 567 + 22.78 kg)were equally divided into two groups.Group one (G1 ),Control,which did not receive Chromium in their rations and group two (G2),treated,received 5 mUhead/day of Chromium methionine in their rations from 6-19 WKs postpartum.Milk production and milk composition were evaluated weekly.Serum biochemicals concentrations (glucose,cholesterol,triglycerides,total protein.cortisol and insulin)were estimated on the 42th,72 th,102th,and 132th,day.The obtained results indicated that dietary Chromium Methionine supplementation produced significant increase in milk production and 7% F C M during the entire period (P < 0.05 ).but no significant change on milk composition.Supplemental Chromium had no significant effect on serum glucose,cholesterol,triglycerides and insulin concentrations.On the other hand,significant increase in total serum protein and decrease in cortisol levels (P < 0.05 )were recorded.
