Maintaining Ewe Bodyweight For A Late Mating, T Marshall
Maintaining Ewe Bodyweight For A Late Mating, T Marshall
Journal of the Department of Agriculture, Western Australia, Series 4
DEPARTMENT OF AGRICULTURE experiments have indicated that the bodyweight of ewes at mating can have a large bearing on lambing performance.
It appears that for every 10 lb. increase in pre-mating bodyweight, an increase of some 3 to 6 per cent, lambs born could be expected, depending on the lambing time.

Superphosphate Deficiency Raises Pasture Oestrogens, H G. Neil, T. Marshall
Journal of the Department of Agriculture, Western Australia, Series 4
A recent field experiment on established pastures at Esperance Downs Research Station has demonstrated a relationship between superphosphate application, pasture oestrogens and oestrogenic response in sheep.
Results of the experiment indicate that on phosphate deficient soils carrying oestrogenic clovers, the levels of oestrogenic materials in the pasture are increased if superphosphate applications are below those recommended for healthy pasture growth.
