Effects of increasing dietary levels of full-fat canola on performance, nutrient retention and bone mineralization

Abstract

full-fat canola for a period of three weeks. Increasing the dietary proportion of full-fat canola significantly reduced feed intake (P<.05) and weight gain (P<.01), without altering feed:gain ratio. Diet had no significant effect on protein retention although there was a significant decrease in fat retention with an increase in dietary levels of full-fat canola (P<.01). This was accompanied by a significant decrease in metabolizable energy (P<.01). Increasing the proportion of dietary full-fat canola significantly reduced the concentration of soap in the digesta (P<.05) and excreta (P<.01). There was no significant effect of the dietary treatments on calcium or phosphorus retention. There was also no effect of the dietary full-fat canola on bone ash, bone calcium, or phosphorus content
