Soybean Meal+Milo, Alfalfa Hay, And Dehydrated Alfalfa Pellets As Protein Sources For Steers Fed Dormant, Native Tallgrass Forage In Drylot, T. Delcurto, R.C. Cochran, A.A. Beharka, E.S. Vanzant, Tiruvoor G. Nagaraja
Soybean Meal+Milo, Alfalfa Hay, And Dehydrated Alfalfa Pellets As Protein Sources For Steers Fed Dormant, Native Tallgrass Forage In Drylot, T. Delcurto, R.C. Cochran, A.A. Beharka, E.S. Vanzant, Tiruvoor G. Nagaraja
Kansas Agricultural Experiment Station Research Reports
Sixteen ruminally-cannulated steers consuming dormant tallgrass-prairie forage were randomly assigned to one of four treatments: 1) control, no supplement; 2) soybean meal (SBM)+sorghum grain; 3) alfalfa hay; or 4) dehydrated alfalfa pellets. Forage dry matter (DM) intake was at least doubled by all three supplemental protein treatments (P<.01). In addition, steers supplemented with dehydrated alfalfa pellets displayed 15% higher forage DM intakes than steers supplemented with SBM+sorghum grain or alfalfa hay. Total DM digestibility did not differ (P>.10) among treatments; however, fiber (NDF) digestibility was depressed in steers supplemented with SBM+sorghum grain or dehydrated alfalfa pellets, compared with controls. Results from this study reinforce the concept that supplemental protein improves forage intake and utilization. Additionally, alfalfa hay and dehydrated alfalfa pellets appear to be at least as effective as …

Effect Of Inoculants And Npn Additives On Dry Matter Recovery And Cattle Performance: A Summary Of 22 Trials, K.K. Bolsen, A. Laytimi, Ronald V. Pope, Jack G. Riley
Kansas Agricultural Experiment Station Research Reports
Results from 22 trials comparing dry matter (DM) recovery and cattle performance of inoculated or non-protein nitrogen (NPN)-treated silages to controls were summarized using paired t-test analysis. Inoculants consistently improved DM recoveries and gains per ton of crop ensiled in both com and forage sorghums. The use of NPN adversely affected nutrient preservation and gain per ton of crop ensiled, particularly for the wetter forage sorghums.

Influence Of Plant Parts On In Vitro Dry Matter Disappearance Of Forage Sorghum Silages, J. White, K.K. Bolsen
Kansas Agricultural Experiment Station Research Reports
Five mid- to late- season forage sorghum hybrids were used to plot the changes in silage in vitro dry matter disappearance (IVDMD) when their proportions of grain, leaf, sheath, and stalk were altered. The average IVDMD of the parts were: grain 76.9%, leaf 57.7%, sheath 52.7%, and stalk 60.8 percent. The grain proportion had a large positive effect on silage IVDMD dynamics, whereas the sheath plant part had a negative effect.

Kansas Agricultural Experiment Station Research Reports
Interseeded grain sorghum and soybeans have been evaluated as a silage crop over a 3year period. In the first 2 years, maximum dry matter (DM) yields occurred at the late-dough stage of the grain sorghum, and interseeded silages had higher crude protein (CP) and acid detergent fiber contents than non-interseeded late-dough stage, grain sorghum control silages. In year 2, seeding grain sorghum and soybeans in alternating IS-inch rows increased DM yield, CP content, and the proportion of soybean plants in the mixture compared to drilled (6-inch spacing) interseeding. Digestibilities of most nutrients were similar in all silages; however, cattle fed …

Dietary Fat And Calcium Level Effect On Feedlot Performance And Carcass Merit In Steers, B. Bock, Robert T. Brandt Jr., D.L. Harmon
Kansas Agricultural Experiment Station Research Reports
Feeding fat increased feed intake and average daily gain, but feed efficiency was not affected. Feeding high levels of calcium (.9%) had no overall effect, but may tend to increase intake when fed with diets that contain primarily vegetable fat or highly unsaturated fat products.
Effect Of Foraform® On Fermentation Of Alfalfa, Corn, And Forage Sorghum Silages, K.K. Bolsen, A. Laytimi, A.D. Drysdale
Effect Of Foraform® On Fermentation Of Alfalfa, Corn, And Forage Sorghum Silages, K.K. Bolsen, A. Laytimi, A.D. Drysdale
Kansas Agricultural Experiment Station Research Reports
Foraform® was evaluated in four trials using alfalfa, corn, and two forage sorghums harvested in 1987 and ensiled in PVC laboratory silos. There was a dramatic crop by Foraform interaction, with Foraform delaying and restricting the fermentations, as expected, in alfalfa and corn. In both forage sorghum hybrids, although the ensiling process was delayed about 24 hours by the Foraform treatment, end-product silages had lower pH values and equal or higher lactic acid levels than untreated silages. Foraform was effective at both 60 to 90 F temperatures in alfalfa, with treated silages having lower lactic and acetic acids, ethanol, and …
Dietary Influences On Pancreatic Amylase And Small Intestinal Disaccharidase Activities In Cattle, K.K. Kreikemeier, D.L. Harmon, K. Gross, C. Armendariz
Dietary Influences On Pancreatic Amylase And Small Intestinal Disaccharidase Activities In Cattle, K.K. Kreikemeier, D.L. Harmon, K. Gross, C. Armendariz
Kansas Agricultural Experiment Station Research Reports
Pancreatic α-amylase activity was 54% higher in cattle fed at twice maintenance energy than in cattle fed at maintenance and was 52% greater in hay-fed than grain-fed cattle. Increased pancreatic α-amylase activity probably represents increased secretion as well. α-amylase activity in small intestinal digesta was greater with increased energy intake and with hay feeding. Small intestine mucosal disaccharidase activities in cattle were unaffected by diet. Lactase activity was highest in the proximal segment of the small intestine and low in both mid and distal segments. Maltase and isomaltase activities were low in the duodenum, but increased toward the jejunum and …

The Reaction Of Slaughter Hog Cash And Futures Prices To Usda Hogs And Pigs Reports (1989), Ted C. Schroeder, J R. Mintert, John M. Blair
Kansas Agricultural Experiment Station Research Reports
This study examined the reaction of slaughter hog cash and futures prices to USDA Hogs and Pigs reports. Over the 1972-87 period, the nearby live hog futures price had $1/cwt or larger absolute price changes on 48% of the trading days immediately after the Hogs and Pigs report release compared to 6% of the days of the release, suggesting that the reports arc providing important new information to the market. Average price moves in cash and futures markets following the report releases were positive, suggesting that price usually increased the day after the reports. Over the 1972-87 period, the cash …

The Genetics Of Lean Growth (1989), David A. Nichols
Kansas Agricultural Experiment Station Research Reports
In recent years, the pork industry has faced numerous challenges. As consumer resistance to fatter meats has increased, the industry has had two options, 1) argue against popular opinion that fat consumption posed a health risk or 2) strive to reduce the fatness of their products. Since the first option is highly unlikely, the NPPC and commodity leaders have moved rapidly, decisively, and aggressively to promote and reposition pork as a vital, healthful part of the U.S. diet. Pork consumption from 1965 to 1985 was reasonably stable (1965, 45 lb; 1985, 44.2 lb). Demand has been stable to declining in …
Effect Of Fish Meal Quality On The Growth Performance Of Weanling Pigs (1989), G R. Stoner, Jim L. Nelssen, Robert D. Goodband
Effect Of Fish Meal Quality On The Growth Performance Of Weanling Pigs (1989), G R. Stoner, Jim L. Nelssen, Robert D. Goodband
Kansas Agricultural Experiment Station Research Reports
The objective of this experiment was to evaluate three fish meal sources added to diets for the early-weaned pig. Fish meal sources were analyzed for total volatile nitrogen (TVN), which is an indicator of protein degradation of the raw material. Regardless of TVN content, pigs fed diets containing fish meal had better average daily gain (ADG) and average daily feed intake (ADFI) than pigs fed a diet without added fish meal. However, TVN content and chemical digestibility estimates of fish meal were associated with growth performance of starter pigs. Feed intake increased as TVN content increased. Although ADG was not …

Comparison Of Growth Of Holstein Heifers Fed100% Or 115% Of Nrc Requirements (1989), M. G. Daccarett, J.L. Morrill
Kansas Agricultural Experiment Station Research Reports
One hundred and one Holstein heifers from the KSU Dairy Unit were used in this experiment. They were assigned to two treatments in which they were fed either 100% or 115% of the 1988 NRC requirements of energy, protein, major minerals, and major vitamins. Body measurements (height, length, heart girth, weight, body condition scores, and backfat thickness) were recorded. Rations for each group were formulated using the average wt of the heifers. Results suggest that feeding 115% of NRC requirements produces larger frame heifers (without excess body condition), with potential for earlier calving, compared to feeding 100% of NRC requirements.; …
Effects Of Winter Herbage Removal On Flint Hills Rangeland, Lisa M. Auen, Clenton E. Owensby
Effects Of Winter Herbage Removal On Flint Hills Rangeland, Lisa M. Auen, Clenton E. Owensby
Kansas Agricultural Experiment Station Research Reports
Intensive-early stocking (lES) in the Kansas Flint Hills has greatly increased livestock production efficiency. The potential for grazing of regrowth on IES pastures the following winter was studied by mowing different plots on a monthly basis from October to April, 19831985. Winter herbage removal had no significant effect on herbage production in the following seasons or on the total nonstructural carbohydrates (TNC) of big bluestem (Andropogon gerardii) rhizomes. Since there was no reduction in herbage yield for any mowing date, cattle producers can apparently restock IES pastures after October 1.

Influence Of Supplemental Protein Concentration On Intake, Utilization, And Quality Of Diet Selected By Steers Grazing Dormant Tallgrass-Prairie, T. Delcurto, R.C. Cochran, L.R. Corah, A.A. Beharka, E.S. Vanzant
Kansas Agricultural Experiment Station Research Reports
Fifteen ruminally and 12 esophageally cannulated steers were randomly assigned to receive low (LP), moderate (MP), and high (HP) crude protein (CP) supplements in a 23-day winter grazing trial designed to evaluate dormant tallgrass forage intake and utilization. Supplemental CP levels were 13, 26, or 39%, respectively. Forage organic matter (OM) intake was greatest (P<.05) for the MP steers. Likewise, fiber (NDF) digestibility and ruminal fill were largest (P<.10) for the MP treatment. Furthermore, the quality of diet selected tended to improve with increasing supplemental protein concentration. Increasing CP concentration in supplements dramatically improves the intake and utilization of dormant forage. In this study, intake and digestibility were optimized with the MP supplement.

Additive-Treated Corn And Forage Sorghum Silages For Growing Cattle, K.K. Bolsen, A. Laytimi, R.A. Hart, F. Niroomand, J. Hoover
Kansas Agricultural Experiment Station Research Reports
Whole-plant corn silages were treated with Ecosyl® or Foraform® in one trial and Biomate® or Biomate + Cold-flo® in the second trial. In both trials, the silages were well preserved, but all were highly unstable in air during the first 3 to 4 weeks of the feed-out period. Foraform-treated silage was 2 to 6 degrees F cooler than its control, but Cold-flo-treated silage was 2 to 8 degrees F warmer during the first 10 days post-filling. Laboratory silo results showed that both control silages fermented extremely fast; however, inoculated silages had slightly lower pH and higher lactic acid values through …

Effect Of Commercial Inoculants On Fermentation Of 1988 Silage Crops, K.K. Bolsen, A. Laytimi, S. Azimi, R.A. Hart, F. Niroomand, J. Bradford, L. Clare
Kansas Agricultural Experiment Station Research Reports
We have measured silage fermentation dynamics in over 50 crops since the development of a 4 x 14 inch PVC pipe, laboratory-scale silo in 1984. In many of these experiments, our objective was to determine how inoculants or inoculant/enzyme combinations affected the rate and efficiency of the ensiling process. Twenty-five different inoculants have been tested over a wide range of ensiling conditions. Results show that the majority of silage inoculants available today are able to supply a high number of lactic acid bacteria (LAB) and to improve silage fermentation in most crops (KAES, Reports of Progress 494, 514, and 539). …
Influence Of Rumen Bypass Fat In Cattle Supplements On Forage Utilization, R.B. Hightshoe, R.C. Cochran, L.R. Corah, D.L. Harmon, E.S. Vanzant
Influence Of Rumen Bypass Fat In Cattle Supplements On Forage Utilization, R.B. Hightshoe, R.C. Cochran, L.R. Corah, D.L. Harmon, E.S. Vanzant
Kansas Agricultural Experiment Station Research Reports
Incorporation of rumen bypass fat into a supplement to be fed with low quality forage did not affect total dry matter digestibility or ruminal dry matter fill. Similarly, no difference in digestibility was observed among types (animal vs. plant) or levels (low vs. high) of lipids used in this study. Rumen bypass fat apparently avoids the negative impact on forage utilization seen with conventional fats.
A Comparison Of Flavor And Tenderness Between Dry-Aged And Vacuum-Aged Beef Strip Loins, K. Warren, Curtis L. Kastner
A Comparison Of Flavor And Tenderness Between Dry-Aged And Vacuum-Aged Beef Strip Loins, K. Warren, Curtis L. Kastner
Kansas Agricultural Experiment Station Research Reports
Starting 3 days postmortem, sections from eight USDA Choice or better, yield grade 4, strip loins were dry-aged (aged unpackaged) or vacuum-aged (aged in vacuum bags) for an additional 11 days. The dry-aged loins lost more (P<.05) weight during aging than vacuum-aged loins, and cooked faster, with less (P<.05) cooking loss than the unaged loins. Vacuum-and dry-aged samples were similar (P>.05) in tenderness, and both were more tender (P<.05) than unaged counterparts. A trained taste panel found no differences in subcutaneous fat flavor. However, lean from the vacuum-aged samples had a more intense sour flavor note and more intense bloody/serumy flavor and metallic notes than either of the other treatments. The lean of dry-aged samples was beefier and had more brown/roasted flavor than vacuum-aged or unaged counterparts.

New Concepts In Breeding Barn Design (1989), D G. Levis
Kansas Agricultural Experiment Station Research Reports
Many existing swine breeding facilities have been designed to control the environment, provide continuous boar-sow contact for stimulating recently weaned sows to cycle, reduce the distance a weaned sow or boar has to be moved for mating, and reduce construction costs by not constructing breeding pens to be used only for mating. Pork producers operating these types of facilities have had problems with efficiency and accuracy of estrous detection, low percentage (70%) of sows bred twice, slick breeding floors, and excessive labor requirements. A breeding facility should be arranged so the work routines, such as estrous detection; moving, mating, and …

Kansas Agricultural Experiment Station Research Reports
Limit-feeding a high protein creep (36% CP) and a high energy creep (16% CP) was compared with no supplementation in a 61-day preweaning trial. Salt was used to limit daily creep intake to 1.5 to 2.0 lb per head. Calves given the limited energy and protein creep feeds outgained (P<.01) the unsupplemented calves by 0.2 lb and 0.3 lb, respectively. Conversion of creep feed consumed to extra gain was 6.7 and 5.3 for the energy and protein creep-fed calves, respectively (salt included). Trucking shrink of the noncreep-fed calves on the day of weaning and shipping was 4.9 lb and 7.0 lb less (P<.05) than that of the energy and protein creep-fed calves, respectively. Postweaning daily gains of the energy creep-fed calves was higher than those of both the protein creep-fed calves (P=.09) and the noncreep-fed calves (P<.01) by 0.3 lb and 0.5 lb, respectively. The energy creep-fed calves consumed more (P<.05) daily dry matter than the protein creep-fed and unsupplemented calves. Little difference was observed in postweaning feed conversion among creep treatments.

The swine industry is at a crossroads that either mayor may not change the way we produce pork in the future. As we head into the 90's, we are entering a new era in terms of growth promotion and carcass modification,which will produce overnight what would have taken generations to select for. Of the compounds tested, porcine somatotropin (pST) has the most potential to alter the structure of the swine industry. Many fear the application of this technology because of potential increases in pork production displacing and leading to fewer producers. Because pork quality will be improved tremendously (50% reduction …

This experiment was conducted to determine the interactive effects of environmental temperature porcine somatotropin (pST) and dietary energy density on the growth performance of finishing pigs. Forty-eight barrows were allotted randomly to four environmental chambers (EC) in a split plot design with two EClwhole plot (WP). Each EC (12 barrows/EC) represented one subplot (SP). The WP 24-h environmental cycles were: thermal neutral (TN), 8 h at 75°F and 50% relative humidity (RH)-1 h transition-14 h at 68°F and 60% RH-1 h transition; and heat stress (HS), 8 h at 95°F and 60% RH-1 h transition-14 h at 82°F and 80% …

There has been no appreciable change in the reproduction status of Kansas dairy herds over the last 25 yr. For example, the average calving interval was 398 days in 1965 and 405 days in 1988. Analysis of other measures show similar results. Although the long-stated management goal for a dairy herd has been a calf-a-year or 365-day calving interval, few herds realize this efficiency. On the positive side, the stability of reproductive performance is noteworthy, since genetic antagonism exists between production and reproduction. From 1965 to 1988, average yearly milk production in production-tested herds (DHI) has increased 41%.; Dairy Day, …
