Studies on biochemical parameters in different physiological states in sheep under semi intensive system of management

Seventy-four Muzzafarnagri sheep were screened in advance stage of pregnancy and early lactation for prevalence of ketosis. Blood glucose levels were 51.94±3.80, 50.98±1.31 and 55.06±1.68 mg % in pregnancy, lactation and dry period, respectively. The serum ketone values was elevated in pregnancy (3.65±0.11 mg %) and lactation (3.55±0.11 mg %) as compared to dry period (3.53±0.17 mg %). Serum total protein and albumin values did not differ significantly during pregnancy and lactation. Values of phosphorus, magnesium and TVFA were not affected by physiological stresses of pregnancy and lactation while a significant increase in calcium during pregnancy (10.88±0.38 mg %) and lactation (9.11±0.60 mg %) than the dry state (7.5±0.64 mg % in) was recorded. The phosphorus level during pregnancy and lactation decreased as compared to dry period. Sodium level decreased in pregnancy and lactation period (190.33±7.41 and 188.43±10.74 mmol/l respectively) than dry period (201.7±5.33 mmol/l). However decrease was not statistically significant. TVFA values increased marginally during pregnancy and lactation periods.
