Fatty acid synthesizing capacity of mammary gland in relation to plasma hormone levels at different stages of pregnancy and lactation in goats



Fatty acid synthesizing capacity of mammary gland in relation to plasma hormone levels at different stages of pregnancy and lactation in goats



Indian Journal of Biochemistry & Biophysics 21(4): 255-259



Both plasma prolactin and cortisol contents in goat experienced significant increase during near-parturition period with maximum on 3rd and 1st day of prepartum, respectively. The rates of activity of glucose 6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase, NADP-isocitrate dehydrogenase, fatty acid synthetase and acetyl-CoA carboxylase of mammary gland increased gradually during late pregnancy with a sharp rise at 10th day of postpartum in the same experimental goats. The activities of all the lipogenic enzymes studied attained maximum at 20th and 30th day of postpartum. Prolactin correlated significantly with rates of activities of mammary enzymes related to lipid synthesis between 20th day of prepartum and 10th day of postpartum. Cortisol exhibited a similar relationship even earlier.
