Blood Biochemical Profiles and Pregnancy Rate of Brahman Crossbred Cows Supplemented with Mineral Mixture

The investigation was expected to assess various mineral mixture supplementation impacts on Brahman crossbred cows' blood biochemical, hematological profiles and pregnancy rate. This study used ninety cows divided into three dietary treatment groups (n = 30/group). treatments were: Concentrate rice straw only as control treatment; diet + A-formulation MM-A B-formulation MM-B treatment. concentration of (including calcium, phosphor, cobalt, copper, sulphur, potassium, zinc, manganese, magnesium, sodium, selenium iron) higher than MM-A. added 0.5 kg/100 kg diet. concentrate mix were restricted 3 20 kg/day (as-fed basis). Feeding conducted until four months. Blood sampling estrous synchronization carried out after weeks treatments. aimed equate the cycle each cow by using 25 mg prostaglandin F2α (Lutalyse™) (injection via intramuscular). Estrous signs observed two days synchronization. Artificial insemination at ten twelve hours from detection, inseminated with post-thawed frozen Belgian Blue bull sperm. Transrectal palpation diagnose cow's 90 artificial insemination. serum samples analyzed for hematology status. results showed that significantly increased (p<0.05) iron. There no significant differences in glucose, total protein, albumin, cholesterol, triglyceride, creatinine, uric acid, urea nitrogen profile. rate (20.7%) (6.67%) (3.33%). It concluded improved several components Crossbred cows.
