    Effects of pork differentiation strategies in Canada on pig performance and carcass characteristics
    (Canadian Science Publishing, 2016-04-19) Zhang, Hongbo; Aalhus, J. L.; Gariépy, C.; Uttaro, Bethany; Lopez-Campos, Oscar; Prieto, Nuria; Dugan, M. E. R.; Jin, Ye; Juarez, M.
    Performance and quality traits were measured in carcasses from combinations of genotype, diet supplement, slaughter weight and carcass chilling regime. Iberian-crossed pigs had lower live animal performance than Duroc and Lacombe. From 70 to 115 Kg, Lacombe pigs grew slightly faster than Duroc. Duroc carcasses had a higher lean percentage and heavier ham and picnic primals and lighter loins and bellies, compared to Lacombe and Iberian. Heavier carcasses had lower lean yield, except those from Iberian-crossed pigs, and bigger bellies. Meat from Duroc-crossed pigs was lighter in colour and higher in marbling, with intermediate values for fat hardness. Iberian carcasses displayed dark meat with intermediate marbling and the hardest fat. Meat from Lacombe pigs was the leanest although, like in all three breeds, marbling scores were higher in heavier carcasses. Generally, supplementing with canola and flax decreased and blast-chilling increased fat hardness values. Dietary canola also seemed to affect meat colour traits, but these effects were not consistent among breeds and slaughter weights. The commercial combination of Duroc breed, control diet and 115 Kg slaughter weight showed a balance in terms of performance, carcass and quality traits. Other combinations evaluated in this study showed potential to efficiently produce differentiated pork.

    Performance of near-infrared (NIR) spectroscopy in pork shoulder as a predictor for pork belly softness
    (Canadian Science Publishing, 2020-08-07) Soladoye, Olugbenga Philip; Lam, Stephanie; Prieto Benavides, Nuria; Uttaro, B.; Aalhus, J. L.; Larsen, Ivy L.; Shand, Phyllis; Gariepy, Claude; Jurez, Manuel
    Pork belly quality indicators are economically relevant in the pork industry. Near-infrared (NIR) spectroscopy of the pork shoulder outer subcutaneous fat layer, belly flop angle and subjective softness scores of the pork belly were measured (n=144) to determine the accuracy of pork shoulder NIR spectroscopy as a predictor of pork belly softness. The NIR spectra hot carcass estimates explained over 80.0% variability in pork belly softness (80.5–90.8%), with low prediction error, suggesting that NIR spectroscopy measured in the pork shoulder is an efficient and accurate indicator of pork belly softness to classify pork bellies for specific market demands
