Conjugated linoleic acid (CLA) has many potential healthful properties, and beef is naturally enriched with CLA. Simple and rapid methods to measure total CLA were investigated to enable sorting of beef carcasses with potential enhanced economic value. Direct alcohol extraction combined with measuring absorbance was simple, accurate and perhaps the most viable method for rapid carcass sorting compared to methods using saponification or methylation followed by extraction.

Seed of four grass species was re-hydrated to 11 pre-determined moisture concentrations ranging from 100 to 600 g kg-1 fresh weight ( FW) to simulate seed maturation during swathing and combining. The performance characteristics of three thermogravimetric and two electronic capacitance methods of moisture determination were evaluated. The thermogravimetric methods had no moisture range limitations and were, in general, more accurate than the electronic methods. The thermogravimetric Koster tester is suitable for grass seeds of all moisture concentrations, and can be easily adapted for use at field sites. The John Deere Moisture- Chek electronic tester is suitable for the rapid determination of moisture in grass seeds but is limited to concentrations of 80–250 g kg-1 FW.

The repartioning effect of CLA was evaluated using 108 pigs (54 gilts and 54 barrows) fed from 61.5 to 106 kg liveweight. Pigs were fed a cereal-based basal diet containing either 2% CLA or 2% sunflower oil (a rich source of α-linoleic acid). Irrespective of gender, pigs fed CLA tended to have reduced feed intakes (−5.2%, P = 0.07), improved feed conversion efficiences (−5.9%, P = 0.06) and similar rates of gain relative to sunflower oil fed pigs. In addition, pigs fed CLA deposited less subcutaneous fat (−6.8%, P = 0.01) and gained more lean (+2.3%, P = 0.03) than pigs fed sunflower oil. These data suggest CLA can be used as a repartioning agent in pigs and that further research to optimize the repartitioning effect is warranted.
