Daily Gain

One hundred and twenty commercial feedlot steers were penned and randomly allocated to three treatments: fed once, twice and three times per day, over a grower through finisher period of 196 d. Feeding frequency had no effect (P > 0.05) on average daily gain, feed intake or efficiency overall. We conclude that there are no beneficial effects in feeding a total mixed diet more frequently to feedlot steers. Key words: Feeding, frequency, gain, steers, feed efficiency

Daily Gain

Forty crossbred steers (initial liveweight: 339 ± 41 kg) were assigned to four equal groups in a 98-d feeding experiment to determine the effects of sodium bentonite supplements (2% of dietary dry matter) on their growth performance. The steers were fed ad libitum a total mixed ration based on direct-cut (two groups) or wilted (two groups) grass silage. One group of steers fed the same silage received the diet without supplementation (control), while the second group received the diet with the sodium bentonite supplement. The steers were housed in pens with electronic headgates in an unheated enclosed feedlot. Feed intake was recorded throughout the experiment and weighing conducted every 2 wk. Apparent digestibilities of dietary components were determined with four steers in a parallel 4 × 4 Latin square experiment. Feed intake, average daily gain (ADG) and the efficiency of feed utilization were higher (P < 0.05) in steers fed wilted than in those fed the poorly fermented direct-cut grass silage. Bentonite increased (P = 0.04) ADG in steers fed the direct-cut grass silage, but in those fed the wilted grass silage ADG was virtually the same for both the control or the bentonite-supplemented steers. Except for energy, digestibility of nutrients was superior (P ≤ 0.05) in the wilted than in the direct-cut grass silage, but there were no effects (P > 0.05) of bentonite. It was concluded that it may be useful to supplement poorly fermented direct-cut silage diets with sodium bentonite, but not those based on wilted grass silage.

Abstract Automatic feeding systems are being used more frequently to understand individual cattle behavior and intake variation when cattle are group housed. The objective of this experiment was to evaluate if bunk preference exists, and if so, how bunk preference affects performance, intake, or efficiency of feedlot steers. Angus steers (n = 123; initial BW = 293 ± 33.8 kg) were blocked by BW and sire and assigned to 1 of 4 pens, each containing 6 automated feed bunks (Insentec RIC; Hokofarm Group, Marknesse, Netherlands), in a randomized complete block design. Steers were fed a common diet and free to consume feed from any bunk within the pen without restriction. A steer’s preferred bunk was defined as the bunk from which the most feed was consumed. In any week, 80% of steers consumed less than 29% of that week’s total feed intake from the preferred bunk, indicating no strong preference for a specific bunk. The maximum weekly feed intake consumed from a preferred bunk was 57%. Further, the percentage of intake from the preferred bunk did not affect overall ADG, feed intake, or G:F (P &gt; 0.64). These results suggest that a few steers may have a relatively strong preference for a specific feed bunk, however this preference was not associated with performance, intake, or efficiency. Researchers can design experiments (at a stocking density of 5 steers per bunk) that restrict or alter an individual animal’s access to any specific bunk, because such access, or lack of access, does not alter the animal’s performance or feed intake.

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.
