Effects of photoperiod on growth and development of ruminants

, : Effects of photoperiod on growth and development of ruminants. Growth regulation in farm animals: 427-453

The review considers (1) the neural pathway involved in the transduction of the photoperiod signal; (2) effects of photoperiod on growth and development in sheep and cattle; (3) effects of photoperiod on secretion of prolactin and other hormones influencing growth (somatotropin, glucocorticoids, insulin, thyroid hormones and beta -endorphins) in livestock; (4) the role of melatonin in the recognition of photoperiod.

Of these, QTLs detected by contrasting the genome of the hypertensive Dahl salt-sensitive (S) rat with two different relatively normotensive str...
