TRIENNIAL LACTATION SYMPOSIUM/BOLFA: Adipokines affect mammary growth and function in farm animals

Area of Science:

• Animal Science
• Endocrinology
• Molecular Biology

Background:

• Mammary fat pads are vital for mammary gland development and morphogenesis.
• Adipokines, signaling molecules from fat cells, are implicated in regulating mammary gland growth and function.
• Receptors for leptin and adiponectin in mammary tissue suggest local or systemic adipokine influence.

Purpose of the Study:

• To review the role of adipokines in mammary cell proliferation, differentiation, lactogenesis, and galactopoiesis in farm animals.
• To examine the function of milk adipokines in neonates.
• To synthesize current knowledge on adipokine regulation of mammary gland physiology.

Main Methods:

• Literature review of existing research on adipokines in farm animals.
• Analysis of studies investigating adipokine expression and function during different physiological stages.
• Synthesis of findings on adipokine interactions with lactogenic hormones.

Main Results:

• Adipokines act as metabolic sensors, regulating mammary growth and function during metabolic shifts like late pregnancy and early lactation.
• Adiponectin and leptin expression levels vary with physiological status and nutrition.
• Adipokines are key regulators of lactogenic hormone action in the mammary gland.
• Adipokines are important for neonatal growth and intestinal development.

Conclusions:

• Adipokines are critical regulators of mammary gland function, impacting growth, lactation, and hormone signaling.
• Adipokines also exert significant influence on the development and health of neonates.
• Further research into adipokines can optimize animal production and offspring health.
