Improving Color Stability Of Beef Top Round, L.M. Sammel, Melvin C. Hunt, Donald H. Kropf Jan 2001

Improving Color Stability Of Beef Top Round, L.M. Sammel, Melvin C. Hunt, Donald H. Kropf

Kansas Agricultural Experiment Station Research Reports

The beef inside round muscle, especially the deep portion, has poor color stability, a troublesome condition for the meat industry. We examined influences of pre-rigor temperature and pH decline on chemistry of the inside (deep) semimembranosus (ISM) and outside (surface) semimembranosus (OSM) in relation to initial color and stability. Cold-boned ISM had a slower chill rate; faster pH decline; more denatured protein; less metmyoglobin reducing ability, oxygen consumption, and water holding capacity; and a lighter, less stable color than the OSM. Cold-boned steaks were two-toned in color and discolored by day 3 of display. Hotboned ISM and OSM chilled at …

Lambert, T.B. Farran, Sean P. Montgomery, H.J. Labrune, James J. Higgins, James S. Drouillard, Randall K. Phebus

Kansas Agricultural Experiment Station Research Reports

Finishing beef steers (615 head) were used in a 152-day experiment to evaluate the effects of feeding 80:0, 60:30 or 30:60 ratios (dry basis) of steam-flaked corn and wet corn gluten feed (WCGF, 30WCGF, 60WCGF) on acid-resistant E. coli and coliforms. On days 114 to 118 ruminal and fecal samples were collected from 180 steers and analyzed for pH, VFA, and total and acid-resistant Escherichia coli (E. coli) and coliforms. Ruminal (P=0.13) and fecal (P=0.10) VFA tended to decrease linearly as CGF increased. Consequently, there was a corresponding numerical linear increase in ruminal pH and a significant linear increase in …

Kansas Agricultural Experiment Station Research Reports

Five hundred seventy-two crossbred beef heifers were used to compare gain and feed efficiency of cattle consuming restricted quantities of energy-dense growing diets containing varying concentrations of Rumensin® and Tylan®. Growing treatments consisted of providing Rumensin at 30 grams per ton of dry matter (R30), or 250 mg per head per day (R250). A third treatment consisted of a Rumensin/Tylan combination, providing 250 and 90 mg per head per day of Rumensin and Tylan, respectively (R250/T90). Average daily gain and feed efficiency during the growing phase were not different (P>0.90) among treatments. Heifers that received R250/T90 during the growing …

Soybean Hulls And Alfalfa For Limit-Fed Cattle, A.M. Trater, C.A. Löest, B.D. Lambert, Evan C. Titgemeyer Jan 2001

Soybean Hulls And Alfalfa For Limit-Fed Cattle, A.M. Trater, C.A. Löest, B.D. Lambert, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

We evaluated the optimal level of alfalfa inclusion in limit-fed, soybean hull-based diets. Steers were fed soybean hull-based diets containing 0 to 30% alfalfa or alfalfa alone. Feed intakes were lower for alfalfa than for soybean hull-based diets. Digestibilities of dry matter and neutral detergent fiber were lower (P<0.05) for alfalfa than for diets containing soybean hulls. Dry matter and neutral detergent fiber digestibilities were similar for different levels of alfalfa in diets containing soybean hulls, although there were positive associative effects between soybean hulls and alfalfa. Rates of liquid passage from the rumen were higher for alfalfa than for soybean hull-containing diets, and increased as alfalfa was added to the soybean hull diets. Solid passage rates also increased with increasing amounts of alfalfa in soybean hull-containing diets. Adding 30% alfalfa to primarily soybean hull diets led to positive associative effects on diet digestibility, but alfalfa additions increased liquid and solid passage rates, suggesting that the benefit was not a result of slower passage of soybean hulls from the rumen.

Effects Of Wet Corn Gluten Feed And Intake Level On Diet Digestibility And Rumen Passage Rate In Steers, Sean P. Montgomery, J.J. Sindt, T.B. Farran, N.J. Pike, C.M. Coetzer, A.M. Trater, James J. Higgins, James S. Drouillard, Evan C. Titgemeyer Jan 2001

Effects Of Wet Corn Gluten Feed And Intake Level On Diet Digestibility And Rumen Passage Rate In Steers, Sean P. Montgomery, J.J. Sindt, T.B. Farran, N.J. Pike, C.M. Coetzer, A.M. Trater, James J. Higgins, James S. Drouillard, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

Including 40% wet corn gluten feed (WCGF) in the diet increased total tract digestion of organic matter and neutral detergent fiber (P<0.01), reduced total volatile fatty acid concentration (P<0.01), increased rumen NH3 concentration (P<0.01), increased rumen pH, and tended (P<0.06) to increase total tract digestion of starch. Furthermore, WCGF increased rumen passage rate of solid digesta (P<0.01) compared to diets containing no WCGF. Limit feeding reduced total tract digestion of organic matter and neutral detergent fiber (P<0.01), decreased total volatile fatty acid concentration (P<0.01), increased rumen NH3 concentration (P<.01), increased rumen pH at 0 and 12 hours after feeding, reduced rumen pH at 4 hours after feeding, and increased rumen liquid passage rate (P<0.02).

Interrelationships Among Carcass Characteristics Of Feedlot Steers And Heifers Selected For Competition, D.A. King, T.E. Lawrence, D.E. Schafer, Michael E. Dikeman Jan 2001

Interrelationships Among Carcass Characteristics Of Feedlot Steers And Heifers Selected For Competition, D.A. King, T.E. Lawrence, D.E. Schafer, Michael E. Dikeman

Kansas Agricultural Experiment Station Research Reports

We evaluated the interrelationships among carcass characteristics of steers and heifers selected from commercial feedlots for competition in the Beef Empire Days live and carcass contests. Because judging criteria are weighted heavily on cutability, the majority of cattle entered were trim and muscular. Within this highly selected group, heifer carcasses had larger ribeye areas, lower hot carcass weights, more ribeye area/100 lbs. of hot carcass weight, and a higher percentage of kidney-pelvic-heart fat than steers. However, steers graded USDA Choice or better 4% more often than heifers. Ribeye area, ribeye area/100 lbs. of hot carcass weight, and percentage of kidneypelvic- …

Evaluation Of Southwestern Kansas Native Grasses, T.T. Marston, D.O. Yauk Jan 2001

Evaluation Of Southwestern Kansas Native Grasses, T.T. Marston, D.O. Yauk

Kansas Agricultural Experiment Station Research Reports

Native grass samples were collected monthly for five years and analyzed for nutrient content. Crude protein and ADF content indicate that grass quality is highest in May and June, then steadily declines until October. Stocker operators may need to begin protein supplementation as early as July to sustain weight gains. Trace mineral values were erratic from year to year and month to month between and within years, indicating that trace mineral supplementation should probably be maintained throughout the grazing season.

Effects Of Vaccinating Beef Dams Precalving And Calves Preweaning With A Pasteurella Haemolytica Vaccine, L.E. Wankel, T.T. Marston, Gerald L. Stokka, J.R. Brethour, Timothy G. Rozell Jan 2001

Effects Of Vaccinating Beef Dams Precalving And Calves Preweaning With A Pasteurella Haemolytica Vaccine, L.E. Wankel, T.T. Marston, Gerald L. Stokka, J.R. Brethour, Timothy G. Rozell

Kansas Agricultural Experiment Station Research Reports

Our objective was to determine if vaccinating dams precalving and calves preweaning for Pasteurella haemolytica could effect serum antibody titers in dams, and the pre- and post-weaning health and performance of their calves. Vaccination increased serum antibody titers in multiparous cows, but not first-calf heifers. Precalving vaccination had minimal effects on mortality and morbidity of calves before or after weaning. Subsequent steer feedlot gains were unaffected by precalving and preweaning vaccinations and carcasses were not affected. However, heifers' weight gains were greater from weaning to one year of age when reared by vaccinated dams.

Factors Affecting Beef Demand, J. Mintert, Ted C. Schroeder, T. Marsh Jan 2001

Factors Affecting Beef Demand, J. Mintert, Ted C. Schroeder, T. Marsh

Kansas Agricultural Experiment Station Research Reports

We investigated factors that have affected beef demand over the last two decades. Beef demand is typically modeled as a function of beef prices, competing meat prices, prices of all other goods, and consumer expenditures. Our comprehensive model also investigated the impact on beef demand of food safety issues, health concerns, and changes in consumer lifestyle and demographics. Results from this analysis help explain changes in beef demand that occurred during the 1980s and 1990s. First, consumer concerns about food safety, as measured by increases in beef recalls, had a negative impact on beef demand over the last two decades. …

Kansas Agricultural Experiment Station Research Reports

A pasture/feedlot field study was conducted to evaluate the effects of a single Ralgro® implant during the stocker phase on steer grazing performance and subsequent feedlot performance and carcass merit. A total of 2,764 steers of Mexican origin averaging 449 lb were assembled in Texas and shipped to Kansas, where they grazed on three intensively-early-stocked Flint Hills pastures. At initial processing, the steers were individually weighed and randomly assigned to either a non-implanted control group or a Ralgro implant group. Ralgro steers gained more (23 lb; P<0.01) than controls during the 82- to 93-day grazing phase. Following the grazing phase, all steers were shipped to a commercial feedlot in southwestern Kansas where steers from each pasture were individually weighed and given a single Component E-S® implant. Immediately after processing, steers from each pasture were sorted into either a light- or heavy-weight pen, regardless of pasture implant treatment, resulting in six feedlot pens. Days on feed ranged from 127 to 197. Control steers gained faster (P<0.01) during the feedlot phase; however, Ralgro steers had higher cumulative weight gains across the combined pasture and feedlot phases (P<0.01) and averaged three fewer days on feed (P<0.05). There were no significant differences for marbling, fat thickness, ribeye area, KPH fat, or yield grade. Ralgro steers had lower (P<0.05) quality grades because of a higher incidence (P<0.001) of steers with B and C carcass maturities.

Influence Of Freestall Building Orientation On Comfort Of Lactating Dairy Cattle During Summer Heat Stress (2001), John F. Smith, Joseph P. Harner, Michael J. Brouk Jan 2001

Influence Of Freestall Building Orientation On Comfort Of Lactating Dairy Cattle During Summer Heat Stress (2001), John F. Smith, Joseph P. Harner, Michael J. Brouk

Kansas Agricultural Experiment Station Research Reports

A trial was conducted during the summer of 2000 to evaluate the effect of freestall building orientation"”east-west vs. northsouth"” on respiration rates of lactating dairy cows, temperature-humidity index (THI) in the barns, barn temperature, and barn humidity. Differences between ambient and barn temperature and THI were higher in east-west vs. north-south orientated barns. Respiration rates were higher in north-south than in east-west orientated structures. The magnitude of differences between barn and ambient temperatures and THI did not fully explain differences in respiration rates between north-south and east-west orientated barns. Other factors such as solar radiation, airflow, and animal stress may …

Effect Of Headlocks On Milk Production And Feed Intake Of Dairy Cattle (2001), John F. Smith, Joseph P. Harner, S.E. Defrain, Michael J. Brouk Jan 2001

Effect Of Headlocks On Milk Production And Feed Intake Of Dairy Cattle (2001), John F. Smith, Joseph P. Harner, S.E. Defrain, Michael J. Brouk

Kansas Agricultural Experiment Station Research Reports

Cows previously trained with headlocks did not increase milk production or feed intake when headlocks were removed. Twoyear- old and older cows did not differ in response to headlocks and neckrails. Prudent use of headlocks increases labor efficiency of a commercial dairy. Managing a dairy without headlocks is a challenge because cows must be sorted and worked off the milking parlor flow. In the case of large milking parlors, it may be necessary to process 50-200 cows per hour. Depending upon the treatment facilities, this number of cows may create a bottleneck in the dairy. For many routine procedures, headlocks …

Management Of Natural Service Bulls On Large Dairies (2001), P.J. Chenoweth, John F. Smith Jan 2001

Management Of Natural Service Bulls On Large Dairies (2001), P.J. Chenoweth, John F. Smith

Kansas Agricultural Experiment Station Research Reports

Natural service (NS) bulls are widely used on large dairy farms despite the wellproven genetic progress achievable through AI. Producers may choose to use NS bulls for a variety of reasons that are discussed below. In this presentation, problems encountered with the use of NS bulls on a large dairy in Kansas are described in relation to reduced reproductive performance on that dairy. Lameness in bulls was considered to be a major contributing factor to reduced herd reproductive performance, with seminal vesiculitis also possibly playing a role. Possible contributing factors for the occurrence of these problems in the bull population …

Drinking Water Requirements For Lactating Dairy Cows (2001), John F. Smith, Joseph P. Harner, S.R. Defrain, Michael J. Brouk Jan 2001

Drinking Water Requirements For Lactating Dairy Cows (2001), John F. Smith, Joseph P. Harner, S.R. Defrain, Michael J. Brouk

Kansas Agricultural Experiment Station Research Reports

A study to determine the amount and location of water consumption in dairy freestall barns located in northeastern Kansas was conducted during the summer of 2000. Three farms, two Holstein farms with either 2-row or 4-row freestall barns and one Jersey farm with 4-row freestall buildings, were used. Summer water usage averaged 30 to 40 gallons per Holstein cow/day and 20 to 40 gallons/cow/day for Jersey cows depending on age and stage of lactation. The farms with Holstein cows had a water usage ratio of 4 to 4.5 lb of water per lb of milk produced and Jersey cows required …

Effect Of Fan Placement On Milk Production And Dry Matter Intake Of Lactating Dairy Cows Housed In A 4-Row Freestall Barn (2001), John F. Smith, Joseph P. Harner, S.E. Defrain, Michael J. Brouk Jan 2001

Effect Of Fan Placement On Milk Production And Dry Matter Intake Of Lactating Dairy Cows Housed In A 4-Row Freestall Barn (2001), John F. Smith, Joseph P. Harner, S.E. Defrain, Michael J. Brouk

Kansas Agricultural Experiment Station Research Reports

Heat stress reduces milk production, feed intake, and reproductive efficiency each summer in Kansas. Without heat abatement procedures, milk production may decline 20- 30% during the summer months. Research has shown that supplemental fan cooling in combination with low pressure feedline sprinklers can reduce the effects of heat stress on milk production and feed intake. One critical issue in heat stress abatement is the location of fans in a 4-row freestall barn. Research conducted during the summer of 2000 on a northeast Kansas dairy found that locating fans over both the feedline and head-to-head freestalls increased milk production 5.8 lb/cow/d …

Influence Of Different Equipment Protocols On Particle Size Determination Of Ground Corn (2001), J C. Woodworth, Jim L. Nelssen, Robert D. Goodband, Michael D. Tokach, Steven S. Dritz Jan 2001

Influence Of Different Equipment Protocols On Particle Size Determination Of Ground Corn (2001), J C. Woodworth, Jim L. Nelssen, Robert D. Goodband, Michael D. Tokach, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Two experiments were conducted to determine the influence of the tapping bar and sieve agitators (balls and brushes) on determining mean particle size and standard deviation of ground corn. Tapping bar had no influence (P>0.10) on mean and standard deviation; however the presence of balls and brushes on sieves decreased (P<0.002) mean particle size and increased (P<0.0001) standard deviation. These results suggest that balls and brushes should be used when determining mean particle size to assist particle flowability. More research should be conducted to determine the effects of the tapping bar and sieve agitators over a wider range of particle sizes.; Swine Day, Manhattan, KS, November 15, 2001

Comparison Of Bioaerosol Sampling Methods For Swine Barns (2001), B Z. Predicala, J E. Urban, S B. Jerez, Ronaldo G. Maghirang, Robert D. Goodband Jan 2001

Comparison Of Bioaerosol Sampling Methods For Swine Barns (2001), B Z. Predicala, J E. Urban, S B. Jerez, Ronaldo G. Maghirang, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

Two bioaerosol sampling methods (Andersen sampler and filtration sampler) were compared. The two samplers were used to assess the bioaerosol loads in two swine finishing barns. They were similar in terms of the species of microorganisms sampled. The persistent strains of microorganisms were various species of the following genera: Staphylococcus, Pseudomonas, Bacillus, Listeria, Enterococcus, Nocardia, Lactobacillus, and Penicillium. However, the use of Andersen sampler resulted in significantly higher bioaerosol concentrations than the filtration sampler. Thus, it appears that filtration sampling can be used for a qualitative survey of bioaerosols in swine barns while the Andersen sampler is suitable for both …

Kansas Agricultural Experiment Station Research Reports

A total of 432 pigs were used to evaluate the effects of Paylean and dietary lysine on finishing pig growth performance, carcass characteristics and tissue accretion. The 12 dietary treatments included Paylean (0, 4.5, and 9.0 g/ton) and 4 levels of lysine. For pigs fed no Paylean, lysine levels were 0.60, 0.80, 1.00, and 1.20%. For pigs fed 4.5 or 9.0 g/ton of Paylean, lysine levels were 0.80, 1.00, 1.20, and 1.40%. The results indicate that pigs fed Paylean need at least 1.0% dietary lysine to optimize growth, carcass parameters, and tissue accretion.; Swine Day, Manhattan, KS, November 15, 2001

Effects Of Feeding Graded Levels Of Ractopamine (Paylean Tm) On Pig Performance In A Commercial Finishing Facility (2001), R G. Main, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A total of 880 pigs were used in a 21-day trial conducted in a commercial research facility to determine the influence of feeding graded levels (0, 4.5, 6.75, and 9.0 g/ton) of ractopamine HCl (PayleanTM, Elanco Animal Health) on pig performance and carcass composition. Ractopamine supplementation improved ADG 17 to 22% and F/G 12 to 20%. Increasing ractopamine dosages resulted in improved F/G, but similar ADG. With the exception of a tendency to increase yield, carcass parameters were not different among treatments. Ractopamine supplementation resulted in improved economic returns ($2.55 to $3.20/pig), which were due to the improvements in carcass …

Kansas Agricultural Experiment Station Research Reports

Two trials were conducted to determine the effects of irradiation of individual ingredients or the whole diet on growth performance in nursery pigs. The response was similar for both trials with pigs fed diets containing irradiated spray-dried animal plasma or soybean meal having increased (P<0.05) ADG compared with pigs fed the control diet with no irradiated ingredients or the complete diet that was irradiated. Also, ADFI (P<0.05) was higher for pigs consuming the diet with irradiated soybean meal compared with those fed the irradiated whole diet. Pigs fed irradiated spray-dried animal plasma also had superior F/G (P<0.05) compared with those fed diets containing irradiated microingredients or if all ingredients had been irradiated before manufacturing. Therefore, irradiation of certain feed ingredients can improve growth performance in nursery, whereas irradiation of all ingredients in the diet or the whole diet does not enhance performance.; Swine Day, Manhattan, KS, November 15, 2001
