AbstractCanadian Western Hard Red Spring (CWRS) wheat is recognized as premium quality wheat, ideal for breadmaking due to its superior milling qualities, baking characteristics and protein content. Organic wheat production is becoming more prevalent in Canada, due to increasing consumer demand for organic wheat products. Differences may exist in the baking and milling quality of wheat grown under conventional and organic management, a result of the dissimilarity between organic and conventional soil and crop management practices. Five CWRS cultivars released from 1885 to 1997 were grown under conventional and organic management and were assessed for their breadmaking potential. Several traits were investigated, including test weight, protein content, flour yield, kernel hardness and several mixograph parameters. Test weight was higher under conventional management, while no differences in protein content were observed between organic and conventionally grown wheat. Higher sodium dodecyl sulfate sedimentation (SDSS) volume, a reflection of gluten strength, was observed under conventional management, while there was a trend towards higher dough strength under organic management. Cultivars differed in grain protein, flour yield, kernel hardness and mixograph parameters, with Park and McKenzie superior to the others, particularly Red Fife, a much older cultivar. Management×cultivar interaction effects suggest that cultivars exhibit somewhat different baking characteristics when grown in the two management systems. There was no evidence that older cultivars (developed prior to the widespread use of pesticides and fertilizers) are better suited, in terms of breadmaking quality, for organic production.

Clean grazing systems for sheep have been developed to minimize helminth challenge to susceptible lambs. Provision of clean grazing relies upon effective control of overwintering helminth infection on pasture and particularly in the post parturient ewe. During early lactation ewes immuno-competence is reduced resulting in the excretion of helminth eggs for approximately six weeks post lambing (Thomas, 1973). Control of this source of infection may be achieved by strategic anthelmintic administration while overwintering pasture infection may be avoided by use of pasture which has not carried sheep in the previous year.Prophylactic anthelmintic administration is unacceptable under an organic management system and consequently alternative strategies must be sought to eliminate the ewe as a source of infection. The objective of the present study was to evaluate strategic transfer of ewes and lambs to a silage aftermath as a means of minimizing helminth challenge to susceptible lambs.
