Effects of feeding level and sex on nitrogen retention and serum insulin-like factor 1 in growing pigs

Extract
Insulin-like growth factor-1 (IGF-1) stimulates many anabolic processes within the body. In entire animals, release of IGF-1 has been shown to be regulated by nutritional status (e.g. starvation/re-feeding) and in reproductive tissues by gonadotropins and steroid hormones (Phillips et al., 1990). To investigate this further the relation between serum IGF-1 and N retention has been studied in entire and castrated pigs at different planes of nutrition and stages of growth.
