Kansas Agricultural Experiment Station Research Reports
Soybeans interseeded with grain sorghum and harvested as a mixed forage silage crop can be used successfully as a feed for growing dairy heifers. However, daily gain is greater when grain sorghum silage plus alfalfa hay or prairie hay supplemented with milo grain and soybean meal is fed.Replacement heifer programs should be cost effective but yield a heifer large enough to be bred to calve by 24 months of age and with a well developed mammary gland relatively free of internal fat. A daily gain of 1.6 to 1.8 lbs appears to be optimum to achieve the desired bodyweight to …

Two field trials were conducted to compare the pasture and finishing performance of heifers spayed by the Kimberling-Rupp(K-R) technique or by flank spaying plus autografting a piece of ovarian tissue into the rumen wall (FS+A). In trial 1, neither spaying method resulted in gains of grazing heifers different from that of intake controls; however, FS+A heifers gained 5.1% faster than K-R spayed heifers. In trial 2, grazing gains of heifers spayed by the two techniques were similar. During the finishing phase, no performance difference was found among intact, K-R, or FS+A heifers in trial 1 or between K-R and FS+A …
Periparturient Disorders In Dairy Cows (1987), Jeffrey S. Stevenson
Periparturient Disorders In Dairy Cows (1987), Jeffrey S. Stevenson
Kansas Agricultural Experiment Station Research Reports
The economic climate in the dairy industry requires producers to operate efficiently to remain competitive. Attention to details and understanding of reproduction, metabolism, digestive functions, milk secretion, and all aspects of husbandry are essential. To be successful, producers must minimize reproductive failure because reproductive performance affects the quantity of milk produced per cow per day of herd life, the number of potential replacements needed to maintain a constant herd size, and the longevity of the cow in the herd. In practice, this translates into well-designed programs of herd health, milking, feeding, and reproductive management that minimize involuntary culling of. problem …
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
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.

Effect Of Limited-Creep Feeding Calves Of Spring-Calving Cows Grazing Native Grass, F. Brazle, Gerry L. Kuhl, L. Corah, K. Zoellner
Kansas Agricultural Experiment Station Research Reports
Two limited-creep feeding trials were conducted with spring-born, suckling calves on native grass. The high-energy creep rations containing an ionophore were fed during the last 63 or 85 days before weaning in the two trials. Creep intake was limited with salt to about 1.5 lb per calf daily. Calves consuming the limited-creep feeds gained .26 to .31 lb more per head daily and required 4.4 to 5.5 lb of creep per lb of extra weaning weight.

Kansas Agricultural Experiment Station Research Reports
An experimental calf starter made from a pelleted commercial type supplement and feeds readily available on the farm was compared to a conventional pelleted calf starter in an attempt to demonstrate an economical alternative to commercial calf starter. Calves fed the experimental starter consumed as much starter and gained as much weight as calves fed the conventional starter, thus demonstrating a potential for savings on feed cost. The project is continuing in an attempt to improve the starter composition.; Dairy Day, 1987, Kansas State University, Manhattan, KS, 1987;

Increasing Litter Size In Swine Herds (1987), Duane L. Davis, Jeffrey S. Stevenson, J Ernest Minton
Kansas Agricultural Experiment Station Research Reports
Management and biological factors combine to limit litter size in swine herds. With present technology, improving litter size depends upon increasing the number born in the first litter and prolonging sow longevity. Methods for improving size of the first litter rely on increasing the number of eggs ovulated and include flushing (increased feed for at least 10 days before breeding), selecting breeds with high ovulation rates, and delaying breeding until after the pubertal or first estrus. The first two methods are the most cost effective under farm conditions. Because litter size peaks at the fourth or fifth litter, it is …
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
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

The Value Of Drip Versus Spray Cooling At Two Flow Rates To Reduce Heat Stress Of Finishing Swine (1987), David A. Nichols, R C. Thaler, James P. Murphy, Robert H. Hines, Jim L. Nelssen
Kansas Agricultural Experiment Station Research Reports
One hundred fifty pigs were used to evaluate the effectiveness of either spray cooling or drip sprinkling to reduce heat stress in finishing swine. In addition, water flow rates of .2 gal/pig/hr and .4 gal/pig/hr were compared. All wetting treatments significantly (P<.01) improved average daily gain and feed intake (P<.05) compared with non-wetted control. No differences were observed in feed to gain ratio among treatments. Drip sprinkling at the higher flow rate resulted in performance equal to that with intermittent spray cooling at both flow rates.; Swine Day, Manhattan, KS, November 19, 1987

Kansas Agricultural Experiment Station Research Reports
A statistical analysis was used to determine which live animal traits are useful in predicting reproductive performance in first-calf heifers. Heifer condition score at calving and change in condition score postcalving, calving difficulty score, and milk production were related to the probability of estrus and pregnancy. Condition score at calving had the greatest impact and, to a great extent, moderates the influence of the other traits.

Additive-Treated Corn Silages For Growing Cattle, K. Bolsen, H. Ilg, B. Kirch, A. Laytimi, Lyle W. Lomas
Kansas Agricultural Experiment Station Research Reports
Whole-plant corn silages were treated with USO3M or Silo-Best Soluble® in one trial and with Garst M-74® in a second trial. In Trial 1 all three silages were well preserved and moderately stable in the air. USO3M silage lost less dry matter during fermentation than control or Silo-Best silages. Cattle fed the USO3M silage made 7.6% faster gains and were 5.2% more efficient than those fed the control silage. Cattle performance with the Silo-Best Soluble and control silages was similar. In trial 2, heifer gains were nearly identical for both control and Garst M-74 silages.

Apramycin For The Early-Weaned Pig (1987), Jim L. Nelssen, G L. Allee, R C. Thaler, W H. Turlington
Kansas Agricultural Experiment Station Research Reports
A total of 108 21-day-old pigs, weighing less than 10 lb, were utilized in two, 28-day trials to compare the effects of feeding high nutrient-density diets with either added apramycin, neomycin, or carbadox on pig performance. In Tria1, pigs fed the diet containing Apralan® gained slightly faster and were more efficient (P<.05) than pigs fed neomycin during the first 14 days postweaning. There were no differences in pig performance in Trials I or II for the entire 28-day period. Two additional 28-day on-farm studies using a total of 427, 21-day old pigs were conducted, feeding a high nutrient-density diet medicated with either apramycin or neomycin plus terramycin. In both on-farm trials, pigs fed apramycin gained faster (P<.05) than pigs fed neomycin plus terramycin for the initial 14 days post weaning. In the second on-farm trial, feed intake was higher (P<.09) during the first 14 days for pigs fed apramycin. Additionally, pigs fed diets medicated with apramycin were slightly heavier (1. 7 and 1.5 additional pounds for the first and second on-farm trials, respectively) at 28 days post weaning compared to pigs fed neomycin plus terramycin. These results indicate that apramycin will improve the performance of early-weaned pigs fed high nutrient-density diets compared to other feed medications.; Swine Day, Manhattan, KS, November 19, 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

Effects Of Flushing, Altrenogest, And Pubertal Status On Litter Traits In Gilts (1987), M T. Rhodes, Duane L. Davis, Jeffrey S. Stevenson
Kansas Agricultural Experiment Station Research Reports
We tested the effects of flushing (3.4 lb extra ground sorghum grain for at least 10 days before estrus) and estrous synchronization with altrenogest on litter traits in gilts. Altrenogest had no effect on litter size or weight, but flushing increased both traits. The response to flushing occurred entirely among gilts artificially inseminated at the pubertal estrus. Pubertal gilts represented approximately 40% of the gilts in our experiment, and their improvement in litter size was almost two pigs. When all gilts were considered, flushing improved litter size by .9 pigs.; Swine Day, Manhattan, KS, November 19, 1987

Using Biotechnology To Improve Growth Rate And Carcass Composition In Swine (1987), Jim L. Nelssen
Kansas Agricultural Experiment Station Research Reports
Biotechnology has developed a number of compounds that partition nutrients away from fat tissue deposition and towards lean (muscle) tissue accretion in swine. Two compounds that have received considerable research attention are porcine somatotropin (growth hormone) and beta agonists. Somatotropin is a naturally occurring protein found in the blood of all mammals. Beta agonists are compounds commonly used in human medicine. Somatotropin and beta agonists can dramatically influence carcass leanness and ultimately pork product quality. Research has shown that porcine somatotropin can increase daily gains up to 19%, improve feed efficiency up to 28%, and reduce backfat thickness up to …

In one large dairy herd, we examined the reproductive performance of 943 cows following early postpartum hormonal therapy utilizing gonadotropin-releasing hormone (GnRH or Cystorelin®) and prostaglandin F2-α (PGF). None of our hormonal treatments improved reproductive efficiency in this herd, whereas earlier studies at the KSU Dairy Teaching and Research Center had proved beneficial. However, cows given PGF to induce estrus at the beginning of the breeding period had similar reproductive performance to control cows, suggesting a potential use for one injection of PGF to allow the breeding of more cows by a target date after calving (e.g., by 65 days).; …
