“…Similarly, oil supplementation in this study tended to increase ADG. In contrast, others (Hardin et al, 1989;Patil et al, 1993) reported no change in ADG with either soybean oil or partially hydrogenated tallow supplementation to grazing steers. Whitney et al (2000) observed a quadratic increase in ADG with soybean oil supplementation to heifers consuming hay; however, no differences where observed in a companion study.…”

“…Brokaw et al (2001) observed no changes in DMI when heifers were supplemented with low levels (0.375 g/kg of BW) of vegetable oil while grazing a summer pasture (75% Bromus biebersteinii). Others (Hardin et al, 1989;Hall et al, 1990;Patil et al, 1993) reported reductions in DMI when lipids were supplemented to high-forage diets when hay was used as the forage source.…”

“…Brokaw et al (2001) evaluated the effect of lipid supplementation on in vivo digestibility of grazing beef cattle; however, the level of soybean oil-supplemented was relatively low (0.35 g/kg of BW) and no effect was observed. Others have evaluated effects of lipid supplementation on in vivo digestibility for high-forage (≥50%) diets using Bermudagrass hay (Hardin et al, 1989;Hall et al, 1990;Patil et al, 1993) or bromegrass hay (Scholljegerdes et al, 2004) as the forage source. Hardin et al (1989) and Hall et al (1990) observed a reduction in NDF digestibility of Bermudagrass hay with lipid supplementation compared with nonsupplementated.…”

Eighteen Angus steers (438 +/- 4 kg of BW) were supplemented with varying levels of corn oil (0 g/kg of BW, none; 0.75 g/kg of BW, MED; or 1.5 g/kg of BW, HI) on rotationally stocked, endophyte-free tall fescue to determine the effect of supplemental oil level on in vivo digestibility, intake, performance, and carcass traits. Pelleted cottonseed hulls were used as a carrier for the oil supplements, and all supplements were offered to steers using Calan gate feeders for individual intake determination. On d 49, each steer was dosed with a controlled-release capsule containing chromium sesquioxide, and fecal samples were obtained 12 d later over a 7-d period to estimate fecal output that, with forage, supplement, and fecal indigestible NDF concentration, was used to estimate DMI and in vivo total diet digestibility. Steers were slaughtered at the end of the 116-d grazing period, and carcass data were collected at 24 h postmortem. Total fatty acid intake linearly increased with corn oil supplementation, and forage DMI, total DMI, and total DE intake were linearly decreased (P < 0.01). The decrease in total DMI was reflected in forage substitution rates greater (P < or = 0.01) than 1, with a trend (P = 0.09) for a greater substitution rate in HI than in MED. In vivo DM, OM, and NDF digestibility were linearly decreased (P < 0.01) by corn oil supplementation. Average daily gain and final BW tended (P = 0.09) to increase linearly in response to oil level. Oil conversion (0.36 kg of BW gain/kg of corn oil) was greater (P < or = 0.05) than zero and did not differ (P = 0.15) between MED and HI. Dressing percent (P = 0.09), carcass weight (P = 0.01), and carcass backfat thickness (P = 0.01) increased linearly with oil supplementation. No treatment effect was observed for carcass LM area, KPH percentage, marbling score, or yield grade (P > 0.10). Oil supplementation to grazing steers linearly reduced forage DMI intake; however, animal performance was maintained and tended to be greater for oil-supplemented cattle. Oil supplementation increased carcass fat thickness and weight without altering other carcass quality parameters.

“…The absence of depressed NDF digestibility with dietary corn additions contrasts with results of some Hall et al, 1989;Hardin et al, 1989), but not all, studies (Jones et al, 1988) of corn supplementation of bermudagrass hay diets. Typically.…”

Two latin squares were conducted to determine the effects on feed intake and nutrient digestion of adding a ruminal buffer or DL-methionine to supplemental ground corn for Holstein steers (avg BW of 286 and 222 kg in Exp. 1 and 2, respectively) with ad libitum access to bermudagrass hay. In Exp. 1, steers were not supplemented (control) or were given .5 (LC) or 1.0% BW/d (HC) of ground corn without or with .021% BW of sodium bicarbonate (B). Total DMI was 2.39, 2.71, 2.79, 2.81 and 2.98% BW (effects of supplementation [P less than .05], level of corn [P less than .05] and buffer [P less than .06]), and OM digested was 3.56, 4.65, 4.65, 4.96 and 5.34 kg/d for control, LC, LCB, HC and HCB, respectively (effects of supplementation and corn level, P less than .05). In Exp. 2, corn levels were .24 and .74% BW/d and .0022% BW of DL-methionine (M) replaced B. Total DMI was 2.85, 3.00, 2.99, 3.22 and 3.34% BW (effects of supplementation and corn level, P less than .05), and digestible OM intake was 3.78, 4.24, 4.30, 4.84 and 5.12 kg/d for control, LC, LCM, HC and HCM, respectively (effects of supplementation and corn level, P less than .05). Overall, changes in feed intake and digestion with additions of a ruminal buffer and DL-methionine to corn supplements were not marked; however, buffer addition increased DMI intake to the greatest degree with 1.0% BW/d of corn.
