Ruminal Temperature

This study evaluated the effects of corn or barley finishing diets on ruminal pH and temperature and their relationship to feed intake events using continuous reticulorumen monitoring of feedlot steers. Average daily ruminal pH and temperature were not impacted (p ≥ 0.17) by diet. However, diet did affect daily variation of ruminal pH and temperature (p < 0.01). Average hourly ruminal pH displayed a diet by hour post-feeding interaction (p < 0.01), where barley-fed steers had greater (p < 0.01) ruminal pH than corn-fed steers at 0, 1, 18, 19, 20, 21, 22 and 23 h post feeding, but had lower (p ≤ 0.05) ruminal pH than corn-fed steers at 6, 7, and 8 h post-feeding. Variation in ruminal pH hour post-feeding also displayed a diet by hour post-feeding interaction (p < 0.01), where barley-fed steers had greater (p ≤ 0.03) variation in ruminal pH at hours 1–17 post-feeding but did not differ (p ≥ 0.16) at 0, 18, 19, 20, 21, 22 and 23 h post-feeding. Additionally, average hourly ruminal temperature exhibited a diet by hour post-feeding interaction (p < 0.01). In summary, basal grain interacted with time post-feeding influencing ruminal pH and temperature in feedlot steers.

Treatment Trends

High linoleic acid sunflower oil (HLSO) was included at 0, 3, 6, or 9% [dry matter (DM) basis] in barley-based finishing diets offered to 60 steers fed individually (n = 15 per dietary treatment). Trends toward improved average daily gain (ADG) (by 13% with 6% HLSO; quadratic, P = 0.08) and feed efficiency (by 7%, linear, P = 0.09) were observed. Steers tolerated 9% HLSO with no adverse effect on performance. Key words: Carcass characteristics, growth performance, linoleic acid, sunflower oil
