Expellor extracted rape and safflower oilseed meals for poultry and sheep
The objective of these studies was to evaluate the feeding value of on-the-farm expellor extracted rape (RSM) and safflower (SM) oilseed meals for poultry and sheep. Rapeseed meal and SM contained 30.7 and 25.8% crude protein (CP) and 21.7 and 8.7% fat, respectively. Rapeseed meal contained a total glucosinolate concentration of 78.3 ..mu..moles/g. A 22-day feeding trial was conducted with 6-day-old chicks. Rapeseed meal and SM replaced 25 or 50% of the soybean meal (SBM) protein in isonitrogenous (23% CP), isocaloric (3250 kcal ME/kg) diets. Birds fed SBM and 25 or 50% SM consumed more (P < .01) daily feed and gained more (P < .01) per day than those fed 25 or 50% RSM. Birds fed RSM had enlarged thyroid glands in comparison to those fed SMB. Two lamb digestion trials were conducted to evaluate the effect of replacing cottonseed meal (CSM) protein with either RSM or SM on nitrogen utilization and DM digestibility. Replacing 100% of the CSM protein with RSM had no effect (P > .05) on dry matter digestibility and N utilization. Nitrogen balance studies indicate that expellor extracted SM may replace up to 75% of the CSM protein in diets for wethers. 8 tables.
