Effect of prolonged exposure to exogenous melatonin on the onset and end of the breeding season and on the growth rate of ewe lambs



Effect of prolonged exposure to exogenous melatonin on the onset and end of the breeding season and on the growth rate of ewe lambs



British Veterinary Journal 146(1): 17-23



The effect of prolonged exposure to exogenous melatonin on the reproductive status and growth rate of ewe lambs was investigated. Ewe lambs (born late March) were given intravaginal melatonin implants on 4 July (group J, n=10) during anoestrus, or 20 December (group D, n=10) during the breeding season. A third group (group C, n=7) received empty implants on 4 July. Plasma progesterone concentrations were used to assess reproductive status.
