Characteristics Of Frankfurters From Preblended Pork (1987), Curtis L. Kastner, Y I. Choi, Donald H. Kropf Jan 1987

Characteristics Of Frankfurters From Preblended Pork (1987), Curtis L. Kastner, Y I. Choi, Donald H. Kropf

Kansas Agricultural Experiment Station Research Reports

Five pork carcasses were used to determine the effects of hot boning and various combinations of salt (0, 1.5, or 3.0%) and a phosphate mixture (0 or 0.5%) on functional, processing, and storage characteristics of preblended pork (preblends). Although hot-boned (HB) preblends had superior functional properties compared to conventionally boned (CB) preblends, HB and CB frankfurters had similar characteristics. More (P(.05) myosin and actin (proteins that cause lean and fat particles to bind together) were extracted from HB than CB preblends. Addition of salt (1.5 or 3.0%) or phosphate (0.5%) generally increased myosin and actin extraction in both HB and …

Compudose® Vs Ralgro®/Synovex-S® Or Synovex-S®/Synovex-S® Reimplant Programs For Finishing Yearling Steers, S.B. Laudert, R.W. Lee

Kansas Agricultural Experiment Station Research Reports

Three field trials were conducted with finishing yearling steers to compare the performance of cattle receiving Compudose® or Ralgro®/Synovex-S® and Synovex-S®/Synovex-S® reimplant combinations. No differences were found between Compudose and the reimplant programs in cattle daily gain, feed efficiency, or cost of gain. Compudose retention was 97.5% in the 1317 head implanted. Synovex-S implant site abscess rate ranged from 5.7 to 15.4%.

Influence Of Mixtures Of High Moisture Corn And Dry Rolled Wheat On Finishing Performance And Carcass Characteristics, B.J. Bock, Robert T. Brandt Jr., D.L. Harmon Jan 1987

Influence Of Mixtures Of High Moisture Corn And Dry Rolled Wheat On Finishing Performance And Carcass Characteristics, B.J. Bock, Robert T. Brandt Jr., D.L. Harmon

Kansas Agricultural Experiment Station Research Reports

Dry rolled wheat and high moisture corn were fed singly and in three combinations in a 132-day finishing trial. Daily gain, feed intake, and final live weight were greatest on the 75% corn:25% wheat diet. Feed efficiencies and carcass characteristics were not affected by grain combination. Daily gain and feed intake tended to decrease as percentage of wheat in the diet increased above 25%.

Whole-Plant Forage And Grain Sorghum Silages For Growing Cattle, B. Kirch, S. Hamma, K. Bolsen, H. Ilg, J. Hoover Jan 1987

Whole-Plant Forage And Grain Sorghum Silages For Growing Cattle, B. Kirch, S. Hamma, K. Bolsen, H. Ilg, J. Hoover

Kansas Agricultural Experiment Station Research Reports

Four trials were conducted to determine the feeding value of whole-plant forage and grain sorghum silages. In general, growing cattle fed grain sorghum hybrids (NK2778, Funk's 550, DeKalb 42Y, DeKalb E67) out performed those fed forage sorghum silages. Only moderate to high grain-content, forage sorghums (Buffalo Canex, Pioneer 947, Acco 351) gave performances that approached the grain sorghums. Low grain-content and nonheading forage sorghums (DeKalb 25E, Funk's G-1990) resulted in the poorest cattle performance. These studies indicate that grain content of a sorghum silage is the major determinant of cattle performance and that whole-plant grain sorghums should produce the fastest …

The Effect Of Season On Response Of Growing-Finishing Pigs To Dietary Fat Levels (1987), G L. Allee, G R. Stoner, M E. Johnston, Jim L. Nelssen Jan 1987

The Effect Of Season On Response Of Growing-Finishing Pigs To Dietary Fat Levels (1987), G L. Allee, G R. Stoner, M E. Johnston, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

This experiment was conducted to examine the influence of season on the response of finishing pigs to practical levels of fat addition. A total of 378 pigs (average initial weight per trial ranging from 83 to 98 pounds) were utilized in four finishing trials conducted during time frames approximating the 4 seasons of the year. Groups of pigs were taken off trial as they reached market weight (230 pounds). There was no season x fat level interaction for any of the criteria measured. Therefore, it is concluded that season has essentially no effect on fat level response. Fat addition influenced …

Dry Cow Management Program (1987), John F. Smith Jan 1987

Dry Cow Management Program (1987), John F. Smith

Kansas Agricultural Experiment Station Research Reports

Dry cows do not require the intensive daily management of cows in early lactation, but the handling of mastitis treatments, feeding regimen, and grouping are of utmost importance in determining how the cows will perform in the subsequent lactation. The dry period is the time we allow for the cow to regenerate milk-secreting tissue, combat mastitis, and prepare for the next lactation. The body condition of each cow should be moderate before drying off. Each quarter should be treated with a commercial dry cow mastitis treatment, then the cow should be separated from the milking herd for observation and fed …

Gonadotropin-Releasing Hormone Improves Conception Rates Of Repeat-Breeders With Previous Reproductive Disorders (1987), Jeffrey S. Stevenson, Edward P. Call Jan 1987

Gonadotropin-Releasing Hormone Improves Conception Rates Of Repeat-Breeders With Previous Reproductive Disorders (1987), Jeffrey S. Stevenson, Edward P. Call

Kansas Agricultural Experiment Station Research Reports

An experiment examining the benefit of treating repeat-breeders with 100 µg GnRH (Cystorelin ®) at the time of third or fourth insemination was conducted in 513 dairy cows of which 93 (abnormal cows) had been diagnosed previously (during the 60 to 90 days postpartum) as having reproductive disorders, including retained placenta, uterine infections, prolonged anestrus, and cystic ovaries. Treatment with GnRH improved conception in normal and abnormal repeat-breeding cows by 13 percentage points or 42%.; Dairy Day, 1987, Kansas State University, Manhattan, KS, 1987;

Effect Of Display Lighting On Fresh Pork Longissimus Packaged In Oxygen-Permeable And Oxygen-Barrier Films (1987), S Hung, Melvin C. Hunt, Donald H. Kropf Jan 1987

Effect Of Display Lighting On Fresh Pork Longissimus Packaged In Oxygen-Permeable And Oxygen-Barrier Films (1987), S Hung, Melvin C. Hunt, Donald H. Kropf

Kansas Agricultural Experiment Station Research Reports

Longissimus samples from seven pork loins were used to determine display color stability when packaged in oxygen-permeable (polyviny lchloride, PVC) film and when vacuum packaged. Color scores were different at all times when evaluation was done under display lighting, with poorest color under Cool White and most desirable color under NAFA or Grolux Wide Spectrum. Since differences were minor or non-existent when evaluation was under a common light, we conclude that a different color rendition caused the differences noted and no photochemical effect occurred.; Swine Day, Manhattan, KS, November 19, 1987

A Comparison Of Raw Soybeans And Soybean Oil As Energy Sources For Finishing Pigs (1987), Robert D. Goodband, Robert H. Hines, R C. Thaler Jan 1987

A Comparison Of Raw Soybeans And Soybean Oil As Energy Sources For Finishing Pigs (1987), Robert D. Goodband, Robert H. Hines, R C. Thaler

Kansas Agricultural Experiment Station Research Reports

Two hundred and seventy pigs averaging 125 lbs were utilized in two growth trials to determine the effects of raw soybeans or soybean oil on finishing pig performance. In each trial, raw soybeans or soybean oil were substituted for milo to provide 2 or 3% added fat. Pigs fed these diets were compared to pigs fed a milo-soybean meal diet (control). In Experiment 1, raw soybeans or soybean oil were added in place of milo in a 15% crude protein, .7% lysine diet. Increasing levels of raw soybeans resulted in greater trypsin inhibitor content compared to the control or soybean …

Characteristics Of Aerial Dust In Finishing Buildings (1987), A J. Heber, M Stroik Jan 1987

Characteristics Of Aerial Dust In Finishing Buildings (1987), A J. Heber, M Stroik

Kansas Agricultural Experiment Station Research Reports

Eleven finishing units were surveyed to study the characteristics of aerial dust and factors that influence dust concentrations. Feed dust was the major portion of the total dust mass and can be minimized with feed additives, less feed wastage, enclosed feed delivery, and periodic cleaning. Ventilation was the primary method for dust removal. Naturally ventilated buildings had higher dust concentrations than mechanically ventilated buildings because of lower average airflow rates, especially during cold weather. Swine workers can minimize respiratory symptoms by wearing face masks.; Swine Day, Manhattan, KS, November 19, 1987

Color Formation And Retention In Fresh Beef, Donald H. Kropf, Melvin C. Hunt, D. Piske Jan 1987

Color Formation And Retention In Fresh Beef, Donald H. Kropf, Melvin C. Hunt, D. Piske

Kansas Agricultural Experiment Station Research Reports

We conducted two studies in response to a severe problem with ground beef color encountered by beef fabricators and retailers. We concluded that: (1) Loss of muscle chemical-reducing capability upon grinding, with subsequent color deterioration, results from both the mechanical effect of grinding and incorporation of oxygen into the beef. (2) Flat, thin, surface muscles from beef carcasses retain more ability to bloom (turn bright red) if they are removed by hot boning or after a relatively short chill period.

Usda-Dhia Sire Summaries-Ai Advantage (1987), Edward P. Call

Kansas Agricultural Experiment Station Research Reports

USDA-DHIA Sire Summaries are published semiannually and provide the dairy industry with an accurate evaluation of the transmitting ability of bulls for milk and milk components. Genetic potential is established at the time of conception. Therefore, current service sires represent the primary means of improving the genetic base of the future herd. Based upon first evaluation of daughters of AI and non-AI bulls, the data clearly indicate the genetic superiority of bulls selected by the AI industry. Dairy producers are strongly urged to select service sires from the Active AI bull listings.; Dairy Day, 1987, Kansas State University, Manhattan, KS, …

The Effects Of Added Niacin During Lactation On Sow And Litter Performance (1987), Robert D. Goodband, Jim L. Nelssen Jan 1987

The Effects Of Added Niacin During Lactation On Sow And Litter Performance (1987), Robert D. Goodband, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

An on-farm field study utilizing 231 sows was conducted to determine the effects of added niacin during a 21-day lactation on sow and litter performance. At farrowing, sows were assigned to one of two dietary treatments that provided either 200 or 1000 mg niacin/day. All Iitters were equalized within dietary treatment by 24 hours following farrowing. All sows had a similar number of pigs born alive, pigs equalized per litter, and average pig and litter birth weights. Feeding sows a diet providing 1000 mg additional niacin did not significantly affect the number of pigs weaned, pig survival, or average pig …

Effects Of Trenbolone Acetate And Zeranol Implants On Performance, Carcass, And Meat Traits Of Young Bulls And Steers, R.D. Johnson, Michael E. Dikeman Jan 1987

Effects Of Trenbolone Acetate And Zeranol Implants On Performance, Carcass, And Meat Traits Of Young Bulls And Steers, R.D. Johnson, Michael E. Dikeman

Kansas Agricultural Experiment Station Research Reports

Implanting young bulls and steers with trenbolone acetate and zeranol (Ralgro ®) resulted in increased slaughter weights and carcasses that tended to have more marbling than those of control bulls. Furthermore, steaks from both implanted bulls and implanted steers tended to have less detectable connective tissue. Control bulls had larger scrotal circumferences and heavier testicle weights than implanted bulls. Other secondary sex characteristics were not affected, but in these bulls slaughtered at an average age of 13.6 months, sexual development was minimal. Implanting steers with trenbolone acetate and zeranol resulted in performance and carcass and meat quality slightly superior to …

Feeding Value Of Wheat And Sorghum Grain As Indicated By Absorbed Nutrients, K.L. Gross, D.L. Harmon, T.B. Avery Jan 1987

Feeding Value Of Wheat And Sorghum Grain As Indicated By Absorbed Nutrients, K.L. Gross, D.L. Harmon, T.B. Avery

Kansas Agricultural Experiment Station Research Reports

Steers fed diets based on dry-rolled wheat or sorghum grain alone or combined (50:50) showed no differences in net portal fluxes of glucose, L-lactate, ammonia, urea, or α-amino nitrogen. Portal blood flow was increased in steers fed the 50:50 diet. Total volatile fatty acid flux into the portal blood tended to be lower for steers fed the sorghum grain diet, which may partially explain the lower feeding value of sorghum grain compared to wheat or the two grains combined.

Evaluation Of Stocking Rate, Compudose® Implants, And Rumensin® Ruminal Delivery Devices Within Intensive-Early Stocking, R.C. Cochran, Jack G. Riley, Clenton E. Owensby, G. Towne, E.S. Vanzant, Ronald V. Pope Jan 1987

Evaluation Of Stocking Rate, Compudose® Implants, And Rumensin® Ruminal Delivery Devices Within Intensive-Early Stocking, R.C. Cochran, Jack G. Riley, Clenton E. Owensby, G. Towne, E.S. Vanzant, Ronald V. Pope

Kansas Agricultural Experiment Station Research Reports

Stocking rate in an intensive-early stocking system (1.25, 1.50, or 1.76 acres per steer) did not influence steer gains. Available forage on loamy upland sites was lower after steer removal on July 15 for the highest stocking rate. However, after late season rest, available forage was similar for all stocking rates. Steer gains were consistently greater for groups implanted with Compudose® (estradiol 78β or Compudose plus a Rumensin® (monensin) ruminal delivery device. The Rumensin device alone was successful in increasing average daily gain only at the highest stocking rate.

Effect Of Bovatec® Level In Supplemental Feed On Performance And Forage Utilization Characteristics Of Wintering Beef Cattle, R.C. Cochran, L.R. Corah, K.A. Jacques, T.B. Avery, K.O. Zoellner, J.F. Higginbotham Jan 1987

Effect Of Bovatec® Level In Supplemental Feed On Performance And Forage Utilization Characteristics Of Wintering Beef Cattle, R.C. Cochran, L.R. Corah, K.A. Jacques, T.B. Avery, K.O. Zoellner, J.F. Higginbotham

Kansas Agricultural Experiment Station Research Reports

Various levels of lasalocid (Bovatec®) added to a protein supplement did not improve weight or condition change of beef cows grazing poor quality winter pasture. Similarly, calf birth weight and most forage utilization characteristics (e.g., intake, passage rate, and fermentation characteristics) were not altered by Bovatec level. Although forage digestibility was influenced by Bovatec level, changes were not sufficient to influence performance characteristics.

Influence Of Sorghum Grain Supplementation On Forage Utilization By Beef Steers Consuming Immature Bluestem, E.S. Vanzant, A.A. Beharka, R.C. Cochran, T.B. Avery, K.A. Jacques Jan 1987

Influence Of Sorghum Grain Supplementation On Forage Utilization By Beef Steers Consuming Immature Bluestem, E.S. Vanzant, A.A. Beharka, R.C. Cochran, T.B. Avery, K.A. Jacques

Kansas Agricultural Experiment Station Research Reports

Supplementing beef steers consuming immature bluestem with 0, 1, 2, or 4 lbs of sorghum grain daily did not affect forage intake. Thus, total intake increased as level of grain increased. Total dry matter, cell wall, and starch digestibilities were mildly depressed with increasing grain. Rumen fill and rates of passage were similar for all treatments, and differences in rumen fermentation characteristics were minimal.
