Effect Of A Low Phytate, Nutrient Dense Corn On Pig Performance, Mike Brumm Jan 2003

Effect Of A Low Phytate, Nutrient Dense Corn On Pig Performance, Mike Brumm

Nebraska Swine Reports

An experiment was conducted to determine the effects of a low phytate, nutrient dense corn variety on pig performance, fecal phosphorus and fecal nitrogen. Experimental treatments were: 1) corn-soybean meal diets formulated with purchased yellow corn; 2) similar diets formulated with 500 FTU/kg phytase; 3) diets formulated with a nutrient dense corn variety having a reduced phytic acid, elevated lysine, and higher energy compared to yellow corn; and 4) diets formulated with the nutrient dense corn variety and phytase at 500 FTU/kg to 130 lb BW and blended with yellow corn thereafter based on estimated available phosphorus. There was no …

Omega-3 Fatty Acids And Swine Reproduction - A Review, Duane Reese Jan 2003

Omega-3 Fatty Acids And Swine Reproduction - A Review, Duane Reese

Nebraska Swine Reports

A literature review was conducted to examine the role dietary omega-3 fatty acids may play in swine reproduction. Omega-3 fatty acids are not normally present to any great extent in practical swine diets, but they are increasingly important in human and pet health. Swine nutritionists have focused primarily on the effect omega-3 fatty acids may have on littler size, piglet preweaning mortality, and boar fertility. Feeding omega-3 fatty acids to sows has not generally improved litter size. Piglet preweaning mortality may be improved by omega-3 fatty acid supplementation provided sows are allowed to farrow naturally (without induction). Boar fertility seems …

Evaluation Of Cow And Calf Performance And Profit Potential In Beef Systems, Rosemary Anderson, Richard J. Rasby, Terry J. Klopfenstein, Casey Macken Jan 2003

Evaluation Of Cow And Calf Performance And Profit Potential In Beef Systems, Rosemary Anderson, Richard J. Rasby, Terry J. Klopfenstein, Casey Macken

Nebraska Beef Cattle Reports

A three-year experiment was conducted to determine the production efficiencies of two beef systems. Spring-calving, crossbred cows were either wintered on pasture (Control System) or on corn stalks (Treatment System). Control System steers were transported to a feedlot, fed a finishing diet and harvested. Treatment System steers were wintered on corn stalks, grazed pasture, fed a finishing diet, and harvested. Cow weights and condition differed but pregnancy rates were similar. Control System steers spent more days in the feedlot, had lower feed conversions and higher marbling scores. Treatment System steers had higher average daily gains and produced heavier carcasses.

The Effects Of Tumbler Volume On Roasted Beef Quality, Mike Baczwaski, Roger W. Mandigo, Jesus Velazco Jan 2003

The Effects Of Tumbler Volume On Roasted Beef Quality, Mike Baczwaski, Roger W. Mandigo, Jesus Velazco

Nebraska Beef Cattle Reports

Semitendinosus beef muscles (n = 108) were used to determine optimum tumbler volume with regards to meat quality. Fill capacity of 2/3 meat had lower shear force values than capacities of 1/2 (P = 0.02) and 1/3 (P < 0 .01). Texture profile analysis showed favorable results among treatments. Hardness was lower with 2/3 capacity than 1/2 (P = 0.02) and 1/3 (P = 0.06). Gumminess favored 2/3 capacity over 1/2 (P = 0.02). Springiness favored 1/2 capacity over 1/3 capacity (P < 0.01) and 2/3 capacity (P=0.04). Purge, absorption rate during tumbling, absorption rate after rest, cooking loss and yield had no effect between treatments.

Quality Traits Of Grain- And Grass-Fed Beef: A Review, Perry Brewer, Chris R. Calkins Jan 2003

Quality Traits Of Grain- And Grass-Fed Beef: A Review, Perry Brewer, Chris R. Calkins

Nebraska Beef Cattle Reports

Carcasses from grass-fed beef have lower fat thickness and lighter carcass weights, which increases the risk for cold shortening and reduces muscle proteolysis, both of which would reduce beef tenderness. A review of nine research papers indicates grass-fed beef is lower in tenderness (both from shear force and by taste panel), flavor and overall acceptability/desirability ratings.

Impact Of Manure Application On Phosphorus In Surface Runoff And Soil Erosion, Christina Gossin, Gregory J. Teichmeier, Galen E. Erickson, Terry J. Klopfenstein, Daniel T. Walters Jan 2003

Impact Of Manure Application On Phosphorus In Surface Runoff And Soil Erosion, Christina Gossin, Gregory J. Teichmeier, Galen E. Erickson, Terry J. Klopfenstein, Daniel T. Walters

Nebraska Beef Cattle Reports

Effects of method of manure management and dietary P were compared on 21 natural runoff plots to monitor the long-term impact of dietary P to P losses in runoff and erosion. Reducing feed P resulted in a 33% reduction in manure P content and soil test P buildup and runoff losses of P also were directly proportional to feed P inputs. The timing and management of manure are also important considerations for controlling P losses in runoff in the year of application. However, residual effects of timing and management are probably small. Management criteria designed to assess the potential for …

Amino Acid Supplementation To Growing Heifers Fed Soypass®, James C. Macdonald, Terry J. Klopfenstein, Casey Macken Jan 2003

Amino Acid Supplementation To Growing Heifers Fed Soypass®, James C. Macdonald, Terry J. Klopfenstein, Casey Macken

Nebraska Beef Cattle Reports

Sixty individually fed heifers were used in an 84-day growing trial to determine effects of adding rumen protected methionine and/or bloodmeal on performance of growing heifers supplemented with Soypass®. Treatments were designed to be a 2x2 factorial with diets supplemented with or without rumen protected methionine and bloodmeal (0.3% of DM) to provide 0.72 g per day of additional histidine as factors. The rumen protected methionine source, Smartamine M®, provided 1.85 g per day of additional methionine. No statistical differences in performance among treatments were observed, suggesting growing animals fed Soypass® do not benefit from addition of supplemental rumen protected …

Supplementation To Meet Metabolizable Protein Requirements Of Primiparous Beef Heifers: Ii. Pregnancy And Economics, H. H. Patterson, Don C. Adams, Terry J. Klopfenstein, R. T. Clark, B. Teichert

Department of Animal Science: Faculty Publications

Metabolizable protein (MP) requirements of spring calving heifers increase over the winter due to advancing gestation. The MP content of grazed winter forage is low, which may result in an MP deficiency. The objective was to compare the response of supplementing pregnant yearling heifers to meet MP requirements versus conventional CP supplementation. In 1997–98 and in 1998–99, pregnant, March-calving heifers (2,120 animals; 358 kg) at two locations of a commercial ranch in the Nebraska Sandhills, were used following breeding through calving as 2-yr-olds (cows). Heifers were randomly allotted to one of two supplementation treatments (about 265 heifers/treatment) each year at …

Modification Of The Penn State Forage And Total Mixed Ration Particle Separator And The Effects Of Moisture Content On Its Measurements, P. J. Kononoff, A. J. Heinrichs, D. R. Buckmaster Jan 2003

Modification Of The Penn State Forage And Total Mixed Ration Particle Separator And The Effects Of Moisture Content On Its Measurements, P. J. Kononoff, A. J. Heinrichs, D. R. Buckmaster

Department of Animal Science: Faculty Publications

The Penn State Particle Separator has led to widespread measurement of forage and total mixed ration (TMR) particle size. However, a large proportion of small particles may pass through both sieves when a TMR is analyzed, and field research has suggested that both shaking frequency and sample dry matter may affect the results. The objectives of this project were to test the effects of an additional sieve with a smaller aperture size, shaking frequency, and sample moisture content on results obtained. A sieve was constructed out of wire with a nominal size aperture of 1.18 mm. Samples of alfalfa haylage, …

Effect Of Feeding Glyphosate-Tolerant (Roundup-Ready Events Ga21 Or Nk603) Corn Compared With Reference Hybrids On Feedlot Steer Performance And Carcass Characteristics, Galen Erickson, N. D. Robbins, J. J. Simon, L. L. Berger, Terry Klopfenstein, E. P. Stanisiewski, G. F. Hartnell

Department of Animal Science: Faculty Publications

Three experiments were conducted to compare the feeding value of genetically enhanced corn (Roundup Ready corn events GA21 and nk603) with nontransgenic hybrids. The four treatments included two separate reference hybrids (REF), the near-isogenic control hybrid (CON), and the genetically enhanced corn (RR), resulting in two preplanned comparisons of CON vs. RR and RR vs. the average of REF. In Exp. 1 (RR event GA21), 175 steers (BW = 427 kg) were fed in 25 pens with seven pens per corn hybrid, except CON, which contained four pens due to limited quantities of that hybrid. In Exp. 2 (RR event …

Corn Processing Method In Finishing Diets Containing Wet Corn Gluten Feed, T. L. Scott, C. T. Milton, Galen Erickson, Terry Klopfenstein, Rick A. Stock Jan 2003

Corn Processing Method In Finishing Diets Containing Wet Corn Gluten Feed, T. L. Scott, C. T. Milton, Galen Erickson, Terry Klopfenstein, Rick A. Stock

Department of Animal Science: Faculty Publications

Two trials were conducted to determine the effect of corn processing method on performance and carcass traits in steers fed finishing diets containing wet corn gluten feed (WCGF). In Trial 1, 480 steer calves (303 kg initial BW) were fed eight finishing diets: 1) dry-rolled corn (DRC) without; and 2) with 32% (DM basis) WCGF; 3) steam-flaked corn (SFC) without; and 4) with WCGF; 5) a combination of DRC and SFC without WCGF; 6) finely-ground corn (FGC) with WCGF; 7) high-moisture corn (HMC) with WCGF; and 8) whole corn (WC) with WCGF. Feeding WC + WCGF increased (P < 0.10) DMI and decreased gain:feed compared with all other treatments. Feeding DRC + WCGF increased (P < 0.10) DMI and decreased (P < 0.10) gain:feed compared with treatments other than WC + WCGF. Steers on treatments that included WCGF gained similarly, regardless of corn processing method, and at a rate 6% faster (P < 0.10) than steers fed diets that did not include WCGF. Gain:feed did not differ among steers fed SFC, SFC + WCGF, SFC + DRC, and HMC + WCGF. Steers fed SFC or SFC + WCGF were more efficient (P < 0.10) than steers fed DRC or FGC + WCGF. In Trial 2, 288 steer calves (382 kg initial BW) were fed six finishing diets: 1) DRC without; and 2) with 22% (DM basis) WCGF; 3) SFC without; and 4) with WCGF; 5) finely rolled corn (FRC) with WCGF; and 6) HMC corn with WCGF. Steers fed DRC + WCGF or FRC + WCGF consumed more DM (P < 0.10) than steers fed DRC, SFC, or SFC + WCGF. Feed intake did not differ between steers fed SFC + WCGF and HMC + WCGF. All treatment groups receiving WCGF consumed more DM (P < 0.10) feed than steers fed DRC or SFC without WCGF. Steers fed SFC + WCGF gained 8% faster (P < 0.10), and steers fed DRC 9.5% slower (P < 0.10) than steers receiving all other treatments. Daily gains did not differ among other treatment groups. Steers fed SFC or SFC + WCGF gained 10% more (P < 0.10) efficiently than all other treatment groups. Feed efficiency did not differ among steers fed DRC, DRC + WCGF, FRC + WCGF, and HMC + WCGF.

Do Crowded Pigs Respond To Paylean®?, Mike Brumm, Phillip S. Miller, Robert C. Thaler Jan 2003

Do Crowded Pigs Respond To Paylean®?, Mike Brumm, Phillip S. Miller, Robert C. Thaler

Nebraska Swine Reports

Paylean® is a feed additive that improves feed efficiency, daily gain and carcass merit in finishing pigs. Restrictions in space allocation are known to reduce daily feed intake and daily gain. Thus, pigs may not respond as expected to dietary additions of Paylean® if feed intake is reduced due to crowding. A 2 x 2 factorial design was used to examine the potential interaction of Paylean® and space allocation. Experimental treatments were: 1)14 or 19 pigs per pen (8.0 vs 5.9 ft2/pig); and 2) Paylean® for four weeks prior to slaughter (0 or 9 g/T). In this experiment, …
