Limit Feeding

Abstract Limit-feeding cows in confinement can lower feed costs; however, calves have limited time to access feed. This study was designed to evaluate management options to economically improve calf performance. Calves (n = 54) were stratified by age (105 ± 16 DOA) and assigned randomly to one of nine groups, then each group assigned randomly to one of three treatments: 1) kept with dam with access to cow diet only (PAIRS) 2) early-weaned (EW) or 3) kept with dam with access to creep (CREEP). The cow diet was 54% wet distillers grains (WDGS), 37% straw, and 8% corn. This diet was fed to meet dry cow requirements (7.7 kg DM/d) for EW, lactation requirements (10.9 kg DM/d) in CREEP, and lactation requirements plus allow for some calf intake (14.8 kg DM/d) in PAIRS. The calf diet consisted of 51% alfalfa hay, 25% WDGS, and 22% corn. Calves in the EW had greater (P < 0.01) intake (5.0 kg DM/d) than CREEP (4.1 kg DM/d) from 105 to 203 DOA. Calf ADG differed (P < 0.01) among treatments from 105 to 203 DOA, with CREEP (1.29 kg/d) being greater (P = 0.02) than EW (1.01 kg/d) and both being greater (P ≤ 0.02) than PAIRS (0.74 kg/d). At ~203 DOA, PAIRS and CREEP were weaned and all calves were fed a growing diet. Calf intakes during the growing phase (223 to 314 DOA) did not differ (P = 0.39). However, calf ADG tended (P < 0.06) to differ. The ADG of PAIRS (1.13 kg/d) and EW (1.10 kg/d) did not differ (P = 0.67) but were greater (P ≤ 0.05) than CREEP (0.92 kg/d). However, when calf value and total feed costs were considered, creep resulted in the most return over feed costs at weaning as well as at the end of growing.

Wet Distillers Grains

Feeding wet distillers grains plus solubles (WDGS) increases polyunsaturated fatty acid (PUFA) levels in beef. It was hypothesised that WDGS in feedlot diets increases PUFA concentration in the sarcoplasmic reticulum (SR) membrane, thereby altering membrane integrity, resulting in more rapid intracellular calcium leakage and improved tenderness. The objective of this study was to evaluate this hypothesis. Ninety-six crossbred steers were fed either a corn-based diet with 0% WDGS or 50% WDGS. Fifteen strip loins per treatment were collected, fabricated into steaks, aged and placed under retail display conditions. Steaks were used to measure tenderness, proteolysis, free calcium concentrations, lipid oxidation, sarcomere length and SR membrane fatty acid, phospholipid lipid, neutral lipid and total lipid profiles. Compared with steaks from steers fed 0% WDGS, steaks from steers fed 50% WDGS were more tender (P < 0.05) and had greater (P < 0.05) free calcium concentrations early post-mortem. Feeding 50% WDGS also tended to increase (P < 0.10) total PUFA concentrations, decrease (P < 0.10) total phospholipid concentration and increase (P < 0.10) total neutral lipid concentration for SR membrane. Steaks from steers fed 0% WDGS had greater (P < 0.05) lipid oxidation (TBARS values) than steaks from steers fed 50% WDGS after extended aging. Although differences in tenderness between the two treatments were detected, there were no corresponding differences (P > 0.10) in sarcomere length or proteolysis. This study showed that feeding WDGS may increase tenderness, possibly by increasing free calcium in muscle early post-mortem. However, the true mechanism that contributes to these differences is still unclear.

Abstract The objective was to evaluate the effects of increasing inclusion of wet distillers grains (WDG) on in vitro ruminal and total tract digestibility in feedlot sheep. Three crossbred ruminally-cannulated male sheep were used as rumen liquid donor. Treatments consisted of isonitrogenous and isoenergetic diets, containing 0, 15, 30 or 45% WDG on DM basis (Control, 15WDG, 30WDG, and 45WDG, respectively). Diets were composed of sugarcane bagasse (20%) and the concentrate (80%) composed of soybean meal (except 45WDG), wheat meal, WDG (except Control), urea, limestone, and mineral-vitamin premix. In vitro digestibility of DM (IVDMD), NDF (IVNDFD), and CP (IVCPD) were performed using the Ankom-DaisyII fermenter. Ruminal digestibility was evaluated after 48h incubation (39°C) using twenty-five filter bags. After 48h, twelve filter bags remained into each jar to evaluate the total tract digestibility. For it, 40mL of 6N HCl and 8g of pepsin were added and incubated for another 24h. The post-ruminal digestibility was calculated by the difference between rumen and total tract digestibility. Data were analyzed using SAS software. Contrasts were used to determine the linear and quadratic effects of WDG inclusions, as well as the contrast Control × WDG treatments. The WDG inclusion linearly decreased the ruminal and total DM and CP digestibility and increased the post-rumen CP digestibility (P &lt; 0.05). When all treatments with WDG were evaluated against the Control, a significant effect was observed for IVDMD, with averages of 68.86 × 77.38%, 5.60 × 0.77% and 71.41 × 78.20%, and for IVCPD, with averages of 68.89 × 95.27%, 21.30 × 1.99% and 90.15 × 97.27%, respectively for rumen, post-rumen and total tract digestibility (P &lt; 0.05). The results indicate that inclusions of WDG at up to 45% in the diets for sheep reduce the ruminal and total DM utilization, however, promote a better post-rumen use of CP of diets.
