Economics Of Using Rbst (1995), John F. Smith Jan 1995

Economics Of Using Rbst (1995), John F. Smith

Kansas Agricultural Experiment Station Research Reports

As new technologies such as rbST become available to dairy producers, evaluating the profitability of those technologies on individual farms is essential. Costs associated with rbST include purchase of product, feed, and labor. The costs of product and labor are independent of milk response. However, feed cost will increase as the milk production response to rbST increases. If the mailbox milk price is $10, approximately 7 lb more milk per day will be required to break even. It is essential that dairy producers have the management in place to achieve a profitable milk response to rbST.; Dairy Day, 1995, Kansas …

Performance Of Cows In The Lactation Following Rbst Treatment (1995), James R. Dunham Jan 1995

Performance Of Cows In The Lactation Following Rbst Treatment (1995), James R. Dunham

Kansas Agricultural Experiment Station Research Reports

The first 305-2x-ME lactation record (after 45 days in milk) projected by the DHI program in 28 cows was not different from their first projected lactation record in a previous lactation in which recombinant bovine somatotropin (rbST) injections were begun by the 90th day of lactation. These results suggest when rbSTtreated cows are fed and managed properly during lactation and the dry period, no negative effect of rbST or so-called "burn out" occurs.; Dairy Day, 1995, Kansas State University, Manhattan, KS, 1995;

Management Strategies: Reproduction (1995), John F. Smith, Jeffrey S. Stevenson Jan 1995

Management Strategies: Reproduction (1995), John F. Smith, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

Despite the negative effects of milk production on some reproductive traits, calving intervals between high- and low-producing groups varied by only 9 days (414 vs 423). First-service conception rates were 8 percentage points greater in the low-producing group than in the high-producing group. However, the percentage of cows not yet inseminated that were more than 120 days in milk was 18 percentage points greater in the low- than highproducing herds. When Kansas dairy herds in the DHIA program are evaluated, the higher producing herds seem to have lower firstservice conception rates and more services per conception. However, managers of high-producing …

Dairy Herd Profitability: Effects Of Milk Yield And Cost Of Production On Net Returns (1995), F.D. Delano, Michael R. Langemeier Jan 1995

Dairy Herd Profitability: Effects Of Milk Yield And Cost Of Production On Net Returns (1995), F.D. Delano, Michael R. Langemeier

Kansas Agricultural Experiment Station Research Reports

Dairy cow herd enterprise records from Kansas Farm Management Association farms over the past 4 years have shown an increase in returns to labor and management from $252 to $355 per cow. Returns for higher milkproducing cows were over $400 each. Cost per hundred weight of milk produced per cow for the higher-producing herds compared with lower-producing herds was about the same. In 1994, for every extra $1.00 spent on feed and other variable costs, the higher-producing herds earned $1.28.; Dairy Day, 1995, Kansas State University, Manhattan, KS, 1995; Typo of author's name L.

Combinations Of Nonprotein Nitrogen And Natural Protein Affect Performance Of Finishing Steers Fed Flaked Corn Diets (1995), B.J. Healy, Robert T. Brandt Jr., T.P. Eck Jan 1995

Combinations Of Nonprotein Nitrogen And Natural Protein Affect Performance Of Finishing Steers Fed Flaked Corn Diets (1995), B.J. Healy, Robert T. Brandt Jr., T.P. Eck

Kansas Agricultural Experiment Station Research Reports

Two hundred crossbred steers (7 85 lb) were used to evaluate the effects of the relative proportion of supplemental nitrogen derived from soybean meal (SBM) and urea. Treatments included an unsupplemented negative control and four 13% CP diets containing SBM:urea proportions (nitrogen basis) of 100:0, 67:33, 33: 67, and 0:100. Steers fed the control diets gained 38% slower (P<.01); ate 4% less feed (P<.10); were 33% less efficient (P<.01); and had lighter carcasses (P<.01) with less backfat (P<.01), less kidney, pelvic, and heart fat (KPH; P<.12), less ribeye area (REA; P<.11) , and less marbling (P<.01) than nitrogen-supplemented steers. Among steers fed supplemented diets, feed intake increased linearly as proportion of SBM increased (P<.01) . Daily gain (P<.05) and feed:gain (P<.05) responded quadratically and was best for steers fed combinations of the nitrogen sources. Similarly, hot carcass weights and backfat thickness were greater (P<.06) for steers fed the mixed supplements. There was a tendency for a linear increase in KPH as proportion of urea in the diet was increased (P<.14). Yield grade, ribeye area, and marbling were unaffected by SBM:urea proportions. In high-concentrate finishing diets, at least some of the supplemental nitrogen should be derived from a natural, degradable-protein source.

Premature Browning In Cooked Ground Beef After Modifying Myoglobin (1995), Melvin C. Hunt, K.E. Warren, Donald H. Kropf, M.A. Hague, C.L. Waldner, Sally L. Stroda, Curtis L. Kastner Jan 1995

Premature Browning In Cooked Ground Beef After Modifying Myoglobin (1995), Melvin C. Hunt, K.E. Warren, Donald H. Kropf, M.A. Hague, C.L. Waldner, Sally L. Stroda, Curtis L. Kastner

Kansas Agricultural Experiment Station Research Reports

Some ground beef patties developed an internal, brown cooked color and looked well-done at temperatures as low as 131 ÌŠF, whereas normal patties were re d to pink. The premature brown color was not relate d to percent fat; patty compaction; animal source and maturity; pH (5.5 to 5.8); or concentrations of raw patty heme and nonhemeiron, myoglobin, and total pigment. Because oxidation-reduction potential and total reducing activities were higher (P<.05) and TBA numbers were lower (P<.05) in normal than prematurely brown patties, the brown color is apparently related to greater patty oxidation.

Relationships Between Weaning Weight, Maternal Weaning Weight, And Milk Production In Polled Hereford Cattle (1995), J.B. Jr. Glaze, R.R. Schalles Jan 1995

Relationships Between Weaning Weight, Maternal Weaning Weight, And Milk Production In Polled Hereford Cattle (1995), J.B. Jr. Glaze, R.R. Schalles

Kansas Agricultural Experiment Station Research Reports

Performance data from a Polled Hereford herd selected for improved feed conversion were used to calculate a variety of genetic parameters. Heritabilities were .14 for weaning wt, .18 for maternal weaning wt., and .19 for milk production. The genetic correlations were -.10 between weaning weight and maternal weaning weight and 0 between weaning weight and milk production. However, the genetic correlation between maternal weaning weight and milk was . 99, indicating they are essentially the same trait. Milk EPDs published by most breed associations are calculate d as the maternal weaning weight. Our study strongly supports this method of estimating …

Dietary Lysine And Slaughter Weight Affect Growth Performance And Carcass Characteristics In Boars And Barrows (1995), M M. Rantanen, Robert H. Hines, I H. Kim, K G. Friesen, Joe D. Hancock Jan 1995

Dietary Lysine And Slaughter Weight Affect Growth Performance And Carcass Characteristics In Boars And Barrows (1995), M M. Rantanen, Robert H. Hines, I H. Kim, K G. Friesen, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

During the growing and finishing period, the boars ate less, had better F/G, and were less fat than barrows. A high plane of nutrition (high vs moderate lysine concentrations for the growing-finishing phases) and decreasing slaughter weight from 260 to 220 lb also improved efficiency of gain and carcass leanness. However, many notable interactions occurred among the gender x lysine x slaughter weight treatments. Also, year (rotational-cross of average health status and lean growth potential vs a terminal-cross of high lean growth potential after repopulation of the farm) had pronounced effects on growth performance and carcass merits such that the …

Can Augers Be Used To Blend Diets On The Farm? (1995), S L. Johnston, Robert H. Hines, S L. Traylor, Joe D. Hancock, Keith C. Behnke Jan 1995

Can Augers Be Used To Blend Diets On The Farm? (1995), S L. Johnston, Robert H. Hines, S L. Traylor, Joe D. Hancock, Keith C. Behnke

Kansas Agricultural Experiment Station Research Reports

Growing/finishing gilts were fed two-, three-, four-, or five-phase diet regimens from 77 to 276 lb. The diets were mixed in either a conventional, horizontal ribbon mixer or a 9 ft auger. No interactions occurred among the mixer type and phase-feeding treatments. Pigs fed diets blended with the auger had similar ADG but slightly (4%) worse F/G compared to those fed diets mixed in the mixer. Finally, the three-phase regimen gave the lowest F/G and the lowest cost of gain.; Swine Day, Manhattan, KS, November 16, 1995

Estimated Budgets For Separate-Site Swine Production (1995), Kevin C. Dhuyvetter, Michael D. Tokach, R D. Jones

Kansas Agricultural Experiment Station Research Reports

Budgets were developed to help Kansas swine producers analyze the economics of separate-site production. Return on investment (ROI) was estimated at 9.5%in each of the three production phases. Returns over total costs were very sensitive to transfer price between phases (weaned pig and feeder pig price) as well as production efficiencies and input costs.; Swine Day, Manhattan, KS, November 16, 1995

Test Weight Affects The Milling Characteristics Of Grain Sorghum (1995), S L. Traylor, Timothy J. Herrman, Keith C. Behnke, Joe D. Hancock Jan 1995

Test Weight Affects The Milling Characteristics Of Grain Sorghum (1995), S L. Traylor, Timothy J. Herrman, Keith C. Behnke, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

As test weight was reduced from normal to intermediate (i.e., from 58 to 52 lb/bu), little change occurred in milling characteristics of grain sorghum. However, as test weight was decreased from intermediate to light (52 to 39 lb/bu), production rate slowed and cost of grinding increased dramatically. Decreasing screen opening size from 8/64 in to 3/64 in also decreased production rates and increased electrical energy costs, with these effects much more pronounced in light test-weight sorghum.; Swine Day, Manhattan, KS, November 16, 1995

Mixing And Clean-Out Properties Of Sulfamethazine And Carbadox In Swine Feed (1995), T Herrman, Keith C. Behnke, T Loughin Jan 1995

Mixing And Clean-Out Properties Of Sulfamethazine And Carbadox In Swine Feed (1995), T Herrman, Keith C. Behnke, T Loughin

Kansas Agricultural Experiment Station Research Reports

Results of this study suggest that carbadox was incorporated uniformly in the feed by mixing. However, the two medicated feed additives containing sulfamethazine did not incorporate uniformly in the feed. The causal mechanism for the poor mixing performance of sulfamethazine was not discovered; however, assay variability was eliminated as a primary source of variation. Flushing the feed mixing, conveying, and sack-off systems twice with ground corn did not eliminate drug carryover. Further investigation of the mixing and clean-out properties of medicated feed additives is warranted.; Swine Day, Manhattan, KS, November 16, 1995

A Comparison Of Risk And Return For Contract And Independent Hog Finishing (1995), J L. Parcell, Michael R. Langemeier Jan 1995

A Comparison Of Risk And Return For Contract And Independent Hog Finishing (1995), J L. Parcell, Michael R. Langemeier

Kansas Agricultural Experiment Station Research Reports

Risks associated with independent hog finishing have prompted producers to seek alternative production and marketing methods. A means of reducing risk has developed through contract hog finishing. Research results indicate that risk-neutral producers require contract base payments ranging from $11.25 to $14.00 per head. Strongly risk-averse producers require contract base payments ranging from $4.75 to $7.75 per head. The lower ends of the ranges are for a contract with performance incentives. The upper ends of the ranges are for a flat contract without performance incentives. Calculated required base payments are similar to those payments currently received by contract hog finishers.; …

Irradiation and vacuum-packaging caused a more intense and stable red color in boneless pork chops. Irradiation up to 2.5 kGy increased cooked internal redness in chilled chops. Oxidative rancidity was greater in aerobic packaging than vacuum-packaging and in irradiated aerobic packaged chops than controls. Irradiation of vacuum-packaged boneless pork chops has promising potential for market acceptance.; Swine Day, Manhattan, KS, November 16, 1995

Effects Of Crowding And Intermittent Feed Intake On Growth Performance And Development Of Stomach Lesions In Finishing Pigs (1995), P Sorrell, L L. Burnham, I H. Kim, G A. Kennedy, Robert H. Hines, Joe D. Hancock Jan 1995

Effects Of Crowding And Intermittent Feed Intake On Growth Performance And Development Of Stomach Lesions In Finishing Pigs (1995), P Sorrell, L L. Burnham, I H. Kim, G A. Kennedy, Robert H. Hines, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

Pigs in uncrowded pens (12 ft^2/pig) consumed more feed, gained at a greater rate, and tended to develop fewer stomach lesions than pigs in crowded pens (6 ft^2/pig). Pigs with ad libitum access to feed consumed more feed and gained at a greater rate than pigs deprived of feed for 24-h periods twice each week. The resulting intermittent feed intake increased the severity of stomach lesions but only for uncrowded pigs. In conclusion, crowding slowed growth for all pigs and increased the severity of stomach lesions. Intermittent feed intake also slowed growth, but its effects on development of stomach lesions …

Kansas Agricultural Experiment Station Research Reports

Eighty crossbred gilts were used in a growth trial to evaluate the effects of increasing dietary energy density on growing-finishing pig growth performance and carcass characteristics. In this trial, adding fat to corn-soybean meal diets with a constant calorie: lysine ratio to increase the energy density during the growing phase (98 to 160 lb) improved feed efficiency with no influence on growth rate. However, increasing the energy content of the diet by adding fat had no benefit during the finishing phase (160 to 233 lb).; Swine Day, Manhattan, KS, November 16, 1995

These results suggest that feeding a complex starter diet improves initial (d 0 to 7 postweaning) growth performance of segregated early-weaned pigs. Feeding either a simple or complex diet with added Turbozyme 160 improves feed efficiency from day 0 to 14 postweaning. However, for the overall experimental period, neither a complex diet nor added Turbozyme 160 had any effect on growth performance.; Swine Day, Manhattan, KS, November 16, 1995

Kansas Agricultural Experiment Station Research Reports

Rate and efficiency of gain were not affected by adding as much as 20% distillers dried grains in isocaloric diets for nursery pigs or 30% in isocaloric diets for finishing pigs. These results demonstrate that the previously suggested maximums of 5% distillers dried grains in nursery diets and 10% distillers dried grains in finishing diets are too conservative. Finally, because the 20% (nursery) and 30% (finishing) treatments were the greatest concentrations used in our experiments, additional growth assays are needed to determine the maximum limits for distillers dried grains in diets for pigs.; Swine Day, Manhattan, KS, November 16, 1995

Kansas Agricultural Experiment Station Research Reports

In a 3 I-d nursery experiment, replacing soybean meal (SBM) with dry-extruded whole soybeans (DEWS) tended to improve F/G (6% overall difference), but ADG was not affected. Adjusting the diet with DEWS to the nutrient:calorie ratio of the diet with SBM did not greatly improve growth performance compared to the diet that was simply formulated to the same concentration of lysine as the diet with SBM. In a second experiment (with finishing pigs), 50 and 100% of the SBM in a corn-based diet was replaced with DEWS. Replacement resulted in 2% greater ADG and 8% better F/G, without significantly increasing …

Kansas Agricultural Experiment Station Research Reports

When eating the same amount of feed, pair-fed pigs were more efficient at using nutrients for growth than pigs injected with lipopolysaccharide (LPS). Approximately 2/3 of the decreased growth of LPS-challenged pigs was due to decreased ADFI and 1/3 was due to decreased feed efficiency (F/G). Determining the optimum diet complexity for a nursery feeding program will depend on the desired balance between growth performance. and feed cost per lb of gain but appears to be independent of immune response to inflammatory challenge. On a practical basis, this suggests that nursery diet complexity should not be influenced by health status.; …
