Degree of Phosphorus Saturation in Manitoba Soils
Posted in: Environment by admin on January 1, 2007 | No Comments
This study was funded by the Canadian Fertilizer Institute and ARDI and is ongoing. One of the things that we are exploring in this study is to compare simple soil test P with the newly formulated degree of phosphorus saturation (DPS) as measures of risk of P loss in runoff from Manitoba soils. Previous studies have shown that the DPS is superior to soil test in measuring the risk of P loss from different soils. However, our preliminary results have shown that for Manitoba soils this may not be so. We have so far obtained better relationships between the amount of P loss in runoff and soil test P compared to DPS. Therefore, further studies will be needed to refine the DPS of Manitoba soils, especially in soils with a history of manure application. The advantage of DPS (over simple soil test P) is that it can be used to define objectively a threshold beyond which the application of phosphorus to soils will not be advisable if the loss of P is to be minimized. Also the runoff studies that we have carried out so far have been in the laboratory using rainfall simulation. We will like to carry out similar studies in the field using rainfall simulation on representative Manitoba soils.

The Efficacy of Nine Different Feed Additives on Mitigating the Effects of Deoxynivalenol (DON) When Consumed by Growing Pigs.
Posted in: Prairie Swine Centre by admin on | No Comments
Deoxynivalenol (DON) is a trichothecene mycotoxin produced by fusarium moulds contaminating cereal and other grains, including corn and wheat. Gross symptoms of DON ingestion include vomiting and feed refusal and it can have serious if not dramatic effects on the financial viability of a commercial pig farm. An experiment was conducted with nursery pigs to test the efficacy of 9 different feed additives on mitigating the effects of Deoxynivalenol (2 ppm DON) contaminated feed. Sixty pens of pigs, 4 pig/pen were fed one of 12 diets for the 22 day experiment, beginning 7 days post-weaning. Treatments were a positive control, (non-contaminated corn) a negative control (2 ppm DON) and the negative control supplemented with one of 9 different feed additives, or in one case a combination of feed additives. In conclusion, approximately 2 ppm DON in the diet of nursery pigs will decrease growth and feed intake by almost 10% if consumed for 3 weeks and feed additives, had no effect on ameliorating the effect of the mycotoxoin, regardless of their mode of action.
