Document Summary
6 classes of hormone based on the chemical characteristics of hormones (know main ones listed: steroids, proteins, glycoproteins, peptides. Leptin: leptin is a protein, encoded by the obese gene, secreted by adipose tissue, leptin doesn"t have any functions. Glucocorticoids (steroids: cortisol (mammals, secreted by the adrenal glands, decrease inflammatory response, catabolic reactions in muscle and adipose tissue to enhance energy metabolism during. Initiation of parturition, milk situation stress & injury. Adrenal cortex: corticosteroids, glucocorticoids, gluconeogenesis- formation of glucose from aa and fa, strong anti-inflammatory effect, sex steroids. Effect of stress on meat quality: long term stress, depletes glycogen stores prior to processing, dark cutting beef, or dark, firm dry port, acute stress, causes pale, soft exudative pork (pse) Improves growth, feed conversion, and efficiency of tissue deposition: decrease fat deposition, an improved beta-adrenergic agonist ractopamine. Thyroid hormones: enhance protein synthesis, calcitonin (affects bone formation)
