Undernutrition suppresses the growth of skeletal muscles and alters the expression of insulin-like growth factor 1 (IGF1), a key mitogen, and myostatin, a potent inhibitor of myogenesis. These changes can explain, at least in part, the reduced growth

Myostatin inhibits myogenesis and there is reduced abundance of the mature protein in skeletal muscles of adult male compared with female mice. This reduction probably occurs after translation, which suggests that it is a regulated mechanism to reduc

Summary Palatability of five beef breeds was assessed using a series of paired comparisons. The participants preferred Angus, Hereford, Friesian crossbred beef to Maine Anjou and Pie Rouge crosses. A method of analysis for non-homogeneous products su

The IGF axis is nutritionally sensitive in vivo and IGFs stimulate myoblast proliferation and differentiation in vitro, while myostatin inhibits these processes in vitro. We hypothesised that underfeeding would reversibly inhibit the myogenic activit

Oestrogenic growth promotants stimulate lean carcass growth and reduce carcass fat in livestock but little is known about their actions on musculo‐skeletal growth per se. To investigate such effects, selected bones and muscles were measured in cast

In post-natal animals, plasma concentrations of IGF-I are tightly regulated by nutritional status. The current study reports that plasma levels of IGF-II in sheep are also regulated by nutrition, but whether plasma IGF-II is increased, decreased or r

Active immunization against gonadotropin-releasing hormone (GnRH), commonly known as immunocastration, has been proposed as an alternative to traditional methods of castrating bulls. This study evaluated the effects of immunocastration on growth, beh

Ten broiler-type chickens at 2 weeks of age were injected daily with 0.5 ml of normal sheep serum while 10 others were similarly injected with 0.5 ml of a sheep anti-IGF-2 serum. Immunization with anti-IGF-2 serum had no significant effect upon body

The relative abundance and location of type 1 IGF receptors in sheep muscles have been measured to determine whether changes occur during post-natal growth and nutritional stress. Using the technique of histological autoradiography, specific binding

Plasma levels of IGFs-I and -II were measured in 4-month-old ewe lambs (n=20) and 2-year-old ewes (n=16), which were well fed (n=18) or fasted (n=18) for 3 days. Half of each nutrition group was given daily (0900 h) injections of bovine GH (bGH, 0·1
