Supplementing Rumen Undegradable Protein To Grazing Cattle, Braden C. Troyer, Bradley M. Boyd, Andrea K. Watson Watson, Terry J. Klopfenstein Jan 2018

Supplementing Rumen Undegradable Protein To Grazing Cattle, Braden C. Troyer, Bradley M. Boyd, Andrea K. Watson Watson, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

A pooled-analysis of previous Nebraska Beef Report Articles examined the impact of rumen undegradable protein (RUP) supplementation for cattle grazing different types of forage. Each lb of RUP supplement increased ADG by 0.63 lb/d when cattle were grazing smooth brome and 0.43 lb/d when grazing warm season grasses. Cattle did not respond to RUP when grazing summer annuals which were high (18.2%) in CP.

Experience Improves The Reliability Of Subjective Measurements Of Temperament In Beef Cattle, Jaime T. Praham, Amy E. Tanner, Mark L. Wahlberg Wahlberg, W. S. Swecker Jr., Ronald M. Lewis Jan 2018

Experience Improves The Reliability Of Subjective Measurements Of Temperament In Beef Cattle, Jaime T. Praham, Amy E. Tanner, Mark L. Wahlberg Wahlberg, W. S. Swecker Jr., Ronald M. Lewis

Nebraska Beef Cattle Reports

Reliability of experienced and inexperienced observers when assessing the behavior of cattle when restrained in a squeeze chute (chute score), and when exiting the chute (exit score), was compared. Overall, experienced observers had higher reliability than inexperienced observers. Increasing the number of individuals scoring an animal decreased the degree of agreement. However, within an acceptable tolerance for difference in scores, such disagreement may be beneficial; it allows for subtlety in interpretations of temperament, which when averaged, may better reflect docility. Reliabilities were higher for exit score than chute score. This may reflect the complexity of the trait being evaluated, with …

Antimicrobial Interventions And Application Time Effects On Ground Beef Quality, Ashley R. Mccoy, Dennis E. Burson, Gary A. Sullivan Sullivan Jan 2018

Antimicrobial Interventions And Application Time Effects On Ground Beef Quality, Ashley R. Mccoy, Dennis E. Burson, Gary A. Sullivan Sullivan

Nebraska Beef Cattle Reports

Small business meat processors can use organic acid antimicrobial interventions to control Shiga toxin-producing E. coli (STEC) when producing ground beef; however, many small producers are concerned about the impact on ground beef quality. The effects of two commonly used organic acids, lactic acid and peroxyacetic acid, were evaluated at short (15 seconds) or extended (3 minutes) raw material dip times on ground beef quality parameters. Beef trim dipped in lactic acid for 3 minutes had a reduction in total aerobic bacteria plate count, but also increased ground beef discoloration and lipid oxidation during retail display. Use of a shorter …

Steer Performance Grazing Corn Residue And Supplemented With Modified Distillers Grains Plus Solubles With Or Without Urea, Robert M. Jones, Robby G. Bondurant, F. Henry Hilscher Hilscher, Jim C. Macdonald Jan 2018

Steer Performance Grazing Corn Residue And Supplemented With Modified Distillers Grains Plus Solubles With Or Without Urea, Robert M. Jones, Robby G. Bondurant, F. Henry Hilscher Hilscher, Jim C. Macdonald

Nebraska Beef Cattle Reports

A growing study was conducted to evaluate the effects of supplementing growing calves grazing corn residue with modified distillers grains plus solubles (MDGS; 3 or 5 lb/d) and with or without urea on growth performance. There were no significant MDGS × urea inclusion interactions observed. Urea inclusion level (0 and 0.12 lb/d) did not affect supplemental intake, ADG, or ending BW. Steers fed 5 lb of MDGS had an increased ADG and a heavier ending BW compared to steers fed 3 lb MDGS daily. Supplemental urea is not necessary when supplementing at least 3 lb MDGS to steers grazing corn …

Evaluation Of Corn Distillers Solubles On Growing Steer Performance, Benjamin H. Hansen, Robert G. Bondurant, F. Henry Hilscher Hilscher, Galen E. Erickson, Jim C. Macdonald Jan 2018

Evaluation Of Corn Distillers Solubles On Growing Steer Performance, Benjamin H. Hansen, Robert G. Bondurant, F. Henry Hilscher Hilscher, Galen E. Erickson, Jim C. Macdonald

Nebraska Beef Cattle Reports

A growing study evaluated increasing inclusions of corn distillers solubles (CDS) at 10, 20, 30, and 40%, or increasing wet distillers grains plus solubles (WDGS) at 10, 20, 30, and 40% compared to a corn control. Corn was replaced by CDS or WDGS in each forage-based diet. Increasing CDS resulted in a quadratic increase for both DMI and F:G. Increasing WDGS linearly increased both DMI and ADG with no effect on F:G. The energy value of CDS is less than that of corn, whereas WDGS had an energy value similar to corn in growing diets with 50% brome hay. A …

Analyses Of Birthdate And Growth In Beef Heifers Categorized By Puberty And Pregnancy Status, Aline Gomes Da Silva, Andy Roberts, T. L. Meyers, Richard N. Funston Jan 2018

Analyses Of Birthdate And Growth In Beef Heifers Categorized By Puberty And Pregnancy Status, Aline Gomes Da Silva, Andy Roberts, T. L. Meyers, Richard N. Funston

Nebraska Beef Cattle Reports

Heifer records were retrospectively evaluated to see if Julian birthdate, cycling status prior to breeding, and body weight collected from weaning through final pregnancy diagnosis differed when heifers were categorized by 5 different approaches: 1) pubertal status prior to estrous synchronization, 2) whether or not detected in estrus at AI, 3) heifers impregnated by AI vs all other heifers, 4) final pregnancy status, and 5) a 5-way classification accounting for AI and pregnancy status (AI pregnant, heifers subjected to AI that subsequently conceived to bull, heifers not AI that were impregnated by bull, heifers subjected to AI that were not …

The Effect Of Harvest Method And Ammoniation Of Corn Residue On Growing Calf Performance, Ashley C. Conway, Robert G. Bondurant, F. Henry Hilscher Hilscher, James C. Macdonald, Terry J. Klopfenstein, Mary Drewnoski Jan 2018

The Effect Of Harvest Method And Ammoniation Of Corn Residue On Growing Calf Performance, Ashley C. Conway, Robert G. Bondurant, F. Henry Hilscher Hilscher, James C. Macdonald, Terry J. Klopfenstein, Mary Drewnoski

Nebraska Beef Cattle Reports

A growing trial was conducted to determine the effect of feeding baled corn residue harvested using three different methods, with and without ammoniation of the residue. Residue harvested with the New Holland Cornrower™ with two rows of chopped stem added to the windrow resulted in a 9% increase in ADG compared to conventional rake and bale harvest or turning off the combine spreader and baling tailing. Ammoniation of residue increased ADG 67% (increase of 1.1 lb/d) over non-ammoniated residue. Feed efficiency was not affected by harvest method, but ammoniation decreased F:G by 13% compared to cattle fed non-ammoniated residue. Although …

Impact Of Corn Oil Removal From Modified Distillers Grains Plus Solubles And Supplemental Corn Oil On Finishing Cattle Performance, Jordan E. Burhoop, Curtis J. Bittner, F. Henry Hilscher Hilscher, Matt K. Luebbe, Jim C. Macdonald, Galen E. Erickson Jan 2018

Impact Of Corn Oil Removal From Modified Distillers Grains Plus Solubles And Supplemental Corn Oil On Finishing Cattle Performance, Jordan E. Burhoop, Curtis J. Bittner, F. Henry Hilscher Hilscher, Matt K. Luebbe, Jim C. Macdonald, Galen E. Erickson

Nebraska Beef Cattle Reports

A finishing study was conducted to evaluate removal of corn oil from modified distillers grains plus solubles (MDGS) and replacement of supplemental corn oil on finishing cattle performance. Four treatments were evaluated: a corn control diet, 40% de-oiled MDGS, 38% de-oiled MDGS plus 2% corn oil to equal the fat content of full fat MDGS, or 40% full fat MDGS. There was a significant improvement in ADG and F:G for cattle fed de-oiled MDGS plus oil compared to other treatments. Cattle fed full fat MDGS had numerically lower ADG and numerically poorer F:G (3.7%) compared with cattle fed MDGS plus …

The Unspoken Psychological Issues With Lesson Horses And How We Need To Address Them, Casey Clark Jan 2018

The Unspoken Psychological Issues With Lesson Horses And How We Need To Address Them, Casey Clark

Murray State Theses and Dissertations

Every day all over the world horses provide much needed therapy and treatment to people in need. They provide physical, emotional, and mental training and healing. Humans depend on them for so much and we have a moral and ethical obligation to be good stewards of our equine companions. This close proximity can take a toll on horses physically and psychologically even in the realm of experienced equine professionals. So many times though it is the small lesson facility that sees hundreds of people each year and makes a profound difference in people’s lives. This can be at a 4-H …
