Trials were conducted to determine the effectiveness of adding elevated levels of NaCl and limestone to the diet of fattening beef steers as a means of improving feedlot performance. In Trial 1, 24 Hereford steers were fed high grain diets containing 0.5% (control), 3%, 5%, or 7% NaCl for 126 days. Growth and feed efficiency were not affected by level of NaCl, although feed intakes, organic matter intakes and carcass weights were reduced at the 7% level as compared with the control. Acetate to propionate ratio increased from 1.9 to 2.8 (P < 0.05) with NaCl supplementation while fecal starch tended to increase from 10.3% to 18.7% (P < 0.12). In Trial 2, 24 steers were fed finishing diets containing 0.5% NaCl (control), 2% limestone, 5% NaCl or 5% NaCl plus 2% limestone for 119 days. Steers consuming 5% NaCl or 5% NaCl plus 2% limestone showed 7.4% and 8.9% increases (P < 0.05) in efficiency of organic matter utilization over those fed the control diet. Addition of limestone to the 5% NaCl diet did not markedly increase performance over that seen with NaCl supplementation alone. Similar to Trail 1, fecal starch concentrations tended to increase (P < 0.10) in diets containing NaCl regardless of limestone supplementation. Use of 5% NaCl in the diet of finishing steers may be useful in increasing feed efficiency. Key words: Beef cattle, sodium chloride, high grain

This experiment was conducted to evaluate the effects of corn or soybean hull incorporation into haylage-based diets on backgrounding calf performance and subsequent feedlot performance. Crossbred steers [n = 48, initial body weight (BW) = 303 ± 3.4 kg] were individually fed dietary treatments consisting of: (1) haylage [17.5% crude protein, dry matter (DM) basis; control], (2) haylage + 20% (DM basis) cracked corn, and (3) haylage + 20% (DM basis) soybean hulls during a 112-d backgrounding period. After the backgrounding period, all steers were adapted to a common high moisture corn-based finishing diet and fed until an ultrasound estimated backfat thickness of 7 mm was obtained. During the backgrounding period, steers fed cracked corn or soybean hulls had greater (P < 0.01) average daily gain, dry matter intake and gain:feed and lower (P = 0.05) plasma urea N as compared with controls. However, when finished on a common high-concentrate diet, steers previously fed cracked corn had greater (P < 0.08) average daily gain, final body weight, and longissimus muscle area than those fed soybean hulls, suggesting that source of supplemental energy during the backgrounding period may influence subsequent feedlot performance.

Abstract Our objective was to determine the effects of dry and wet conditions during the preweaning on subsequent feedlot performance and carcass characteristics of beef cattle. Steers (n = 7,432) and heifers (n = 2,361) finished in 16 feedlots in southwestern Iowa through the Tri-County Steer Carcass Futurity Cooperative were used for a retrospective analysis. Cattle originated in the Midwest (Iowa, Missouri, Indiana, Illinois, and Minnesota) and were born in February, March, or April of 2002 through 2013. Feedlot performance and carcass composition data were obtained for each animal. Palmer Drought Severity Index (PDSI) values were obtained for each animal’s preweaning environment on a monthly basis. Mean PDSI values were used to classify conditions as dry (≤−2.0), normal (&gt;−2.0 and &lt;2.0), or wet (≥2.0) for the cool (April and May), warm (June through August), and combined (April through August) forage growing seasons preweaning. Mixed models were used to evaluate the effects of PDSI class on subsequent performance. Calf sex, date of birth (as day of year), year, and feedlot were also included as fixed effects. When considering PDSI class during the cool season, cattle from normal and wet classes had a greater feedlot delivery BW (P &lt; 0.0001) than dry. Dry and normal classes had greater (P ≤ 0.02) delivery BW than wet during the warm and combined seasons, however. For the cool season, average daily gain was greater (P &lt; 0.0001) for the dry class than normal and wet. Cattle from the normal class for the cool season had greater (P = 0.001) final BW than wet, but the wet class had the greatest (P &lt; 0.04) and dry class had the lowest (P &lt; 0.01) final BW during the warm season. During the cool season, HCW was greater (P &lt; 0.007) for the normal than wet class, although HCW was greater (P ≤ 0.02) for wet compared with dry and normal during the warm season. Calculated yield grade was lower (P ≤ 0.006) for the normal class during the cool season compared with dry and wet. For both the warm and combined seasons, the dry class had lower (P ≤ 0.004) calculated yield grade compared with normal and wet. Carcasses from cattle that experienced normal or wet warm seasons had greater (P ≤ 0.0005) marbling scores than dry, and normal had greater (P = 0.0009) marbling score than dry for the combined seasons. In conclusion, these data indicate that both dry and wet conditions during the preweaning phase may impact ultimate feedlot performance and carcass composition.
