The animals were slaughtered at a 132-kg body weight (BW) on average, followed by physicochemical analyses and sensory evaluation on <i>Longissimus lumborum</i> (LL) and <i>Semitendinosus</i> (ST) muscles.

However, only data on heights of white pine blister rust (WPBR) cankers and post-treatment effects from outside the Oregon East Cascades (OEC) have previously informed INW pruning guidelines. To evaluate the appropriateness of these guidelines for WWP in the OEC, heights to cankers on young WWP (&lt;30 years old) were measured in 120 plots within 12 stands throughout the OEC. Canker heights were analysed for live WWP ≥2.54 cm in diameter at 1.37 m. Incidence and severity of WPBR on live WWP, in addition to heights to cankers, varied among stands. Increased severity of WPBR (number of cankers on live-infected trees and percent mortality by WPBR) was observed in stands with the alternate host <i>Ribes</i> more frequently occurring in plots. Of all cankers, approximately 97% were found in the lower half of the total tree height, and only 10% of cankers on young WWP were found above the first third of the total tree height.
