V.  aFlushing responses from heavy and light ewes.  c1980  aAbstract: With the recognition of the separate effects of ewe mating weight (?static?) and the flushing response (?dynamic?) on ewe reproductive performance in the 1960s (Coop, 1966)) ewe liveweight at mating has received the most emphasis. There has, however, been little response in the national lambing percentage since that time. It is common practice in many areas of the country, especially those prone to autumn drought, to allow ewes to gain weight during the spring and early summer feed surplus, but inevitably many of these ewes are losing weight during the drier period prior to and during mating. For these reasons the response of heavy and light ewes to a range of pre-mating pasture allowances was examined  aAnimal reproduction  aDry period (lactation)  aEwes  aLiveweight gain  aReproductive efficiency  aSheep1 aJAGUSCH, K.
