The steers were blocked into six groups based on BW and pen location, with five steers per pen. The treatments consisted of 0, 15, 30, and 45 mEq of DEB/100 g of DM. Average daily DMI increased linearly (P < .01) with increasing DEB for the first 28 d then increased quadratically (P < .05) for the remainder of the study. Daily gain tended (P < .10) to increase quadratically, whereas gain:feed was not affected by DEB. Carcass marbling score increased quadratically (P < .05), but other carcass measurements were not affected by DEB. On d 42, arterial blood pH was increased quadratically (P < .10) and HCO3 responded cubically (P < .10) to DEB, whereas ionized Ca, pCO2, and pO2 were not affected by treatment. On d 84, pCO2 (P < .10) and HCO3 (P < .05) decreased linearly as DEB increased. On d 42, plasma concentrations of Na, K (P < .10), and Mg (P < .05) decreased quadratically with increasing DEB. Plasma CV concentrations decreased linearly (P < .05) with increasing DEB on d 42. On d 84, total plasma Ca increased linearly (P < .10) with increasing DEB.(ABSTRACT TRUNCATED AT 250 WORDS)}, number={6}, journal={JOURNAL OF ANIMAL SCIENCE}, author={ROSS, JG and SPEARS, JW and GARLICH, JD}, year={1994}, month={Jun}, pages={1600–1607} }

Treatments consisting of 0, 15, 30, or 45 mEq of DEB/100 g of DM were obtained by varying NH4Cl and NaHCO3. Average daily gain showed a linear increase (P < .05) with increased DEB for the first 28 d and a quadratic response (P < .05) for the remainder of the 84-d study. Average daily feed intake was not affected by DEB the first 28 d. However, feed intake over the entire feeding period showed a linear increase with increasing DEB (P < .01). On d 28, plasma Na, K, and Mg were not affected by DEB, whereas Ca followed a quadratic pattern (P < .10). On d 84, plasma Na and Mg decreased linearly with increasing DEB. Plasma Cl concentrations decreased linearly (P < .01) with increased DEB on d 28 and 84. On d 28 arterial blood pH and HCO3 increased linearly (P < .05) with increased DEB, whereas ionized Ca, pCO2, and pO2 were unchanged. On d 84, arterial blood pH (P < .10), HCO3 (P < .05), and ionized Ca (P < .10) increased quadratically, whereas pO2 and pCO2 were not affected by treatment. Ruminal pH increased linearly (P < .05) with increased DEB on d 28 but showed no differences on d 84. These data indicate that DEB affects performance and systemic values in growing feedlot cattle. A DEB in the range of 15 to 30 mEq seemed to provide normal homeostasis of growing steers fed a corn silage-based diet.}, number={7}, journal={JOURNAL OF ANIMAL SCIENCE}, author={ROSS, JG and SPEARS, JW and GARLICH, JD}, year={1994}, month={Jul}, pages={1842–1848} }
