Concentrations of adiponectin, leptin, ghrelin and resistin in goat colostrum and mature milk from seven breeds

The importance of passive or humoral immunity, through absorption of colostral antibodies or immunoglobulin is well recognised. White adipose tissue, considered a passive site of lipid storage, is reported to have a role in metabolic and  endocrine functions; secreting a range of hormones known as adipokines such as adiponectin, leptin, ghrelin and resistin. In addition, these major adipokines have been found in human milk and in some livestock species. There is a paucity of literature regarding hormones that may be associated with energy metabolism in goats, thus the objective of this study was to measure the concentration of adiponectin, leptin, ghrelin and resistin in goat colostrum and mature milk from seven different breeds.breed effect was found for all hormones except milk ghrelin concentration.  Leptin concentration was greater in milk, and in colostrum, for the GU and PY, respectively, with no differences between colostrum and milk concentration for the other breeds.  Adiponectin concentration was greater in colostrum than in milk for all breeds except for the PY breed. Ghrelin concentrations were greater in colostrum than in milk for the PAL, TNF and VE breeds. Resistin
concentration was greater in milk than in colostrum for GU, PY and VE breeds.
