dc.description.abstractIn this study, leptin, ghrelin, irisin and insulin hormone levels in milk serum and blood plasma, and non-esterified fatty acids (NEFA), beta hydroxy butyric acid (BHBA), triglyceride and glucose levels in blood plasma which are involved in energy, carbohydrate and fat metabolism were determined in the first week of the early lactation period of seven Holstein cattle aged between 3-6 years old. Blood and milk samples were taken from cattle immediately after calving (0th hour) and on 3rd and 7th postpartum days. In the findings, both plasma ghrelin, leptin, insulin, and milk irisin values were statistically different (p < 0.05) between 0th hour and 3rd day, between 3rd day and 7th day measurements. Both plasma irisin and milk leptin values were statistically different (p < 0.05) between 0th hour and 3rd day, between 0th hour and 7th day, and between 3rd day and 7th day measurements. In addition, when milk ghrelin, irisin, insulin and plasma NEFA and glucose values were examined, a statistical difference was found between 0th hour data and 3th day data, and between 0th hour data and 7th day data (p < 0.05) of each parameter. In conclusion, in this study, differences in blood plasma and milk serum levels of metabolic hormones were noted in the first week of the early lactation period. It has been determined that the newly discovered irisin hormone increases in the first week of the early lactation period after birth. Although, there is no statistically significant relationship, determined negative correlation between plasma irisin hormone and plasma glucose value shows that irisin hormone plays a role in energy homeostasis and is a regulator of glucose metabolism.en_US
