Kansas Agricultural Experiment Station Research Reports

A total of 180 barrows (initially 7.4 or 11.9 lb and 9 or 19 d of age) was used in a growth assay to determine the influence of two weaning ages and three diet complexity sequences on growth performance and carcass characteristics. The growth performance of pigs used in this trial was excellent, as shown by the range of average age at 240 lb from 144 to 149.7 d. Growth performance was similar regardless of weaning age. Thus, when health status and environment are similar, pigs weaned at 19 d of age can attain a weight of 240 Ib at …

Rate And Extent Of Losses From Top Spoilage In Alfalfa Silages Stored In Bunker Silos (1994), D.L. Holthaus, Matthew A. Young, L. Pfaff, B.E. Brent

Kansas Agricultural Experiment Station Research Reports

Alfalfa silages were made in pilot- and farm-scale silos, and five sealing treatments were compared. After 90 days, sealing dramatically reduced dry matter (DM) losses at the 5 and 10 inch depths in the farm silos and at the 0 to 12, 12 to 24, and 24 to 36 inch depths in the pilot silos. Extending the storage period to 180 days in pilot silos had no effect on DM losses for sealed or delay-sealed silages, but DM losses for unsealed silages continued to increase at all three depths. Placing a roof over the unsealed, farm-scale silo increased the silage …

Raising Dairy Heifers: A Business (1994), J.L. Morrill Jan 1994

Raising Dairy Heifers: A Business (1994), J.L. Morrill

Kansas Agricultural Experiment Station Research Reports

On many dairy farms, improvement is needed in raising replacement heifers, especially in providing proper nutrition and management to allow for freshening at 23 to 24 mo of age at a desirable size. With larger herds, there is a trend toward more specialization, which may (but may not) result in more attention to, or responsibility for, proper care and management of the heifer. In some cases, the heifers are raised by a person at a location away from the dairy farm on which they originated, and contract raising of dairy replacements has several potential advantages and disadvantages. These are discussed …

Stage Of Lactation Profile Reflects Nutrition And Management (1994), James R. Dunham Jan 1994

Stage Of Lactation Profile Reflects Nutrition And Management (1994), James R. Dunham

Kansas Agricultural Experiment Station Research Reports

The Stage of Lactation Profile (SOLP) is a good estimate of the shape of the lactation curve for dairy herds. The SOLPs for herds with various milk production levels are somewhat similar. The rates of decline of all SOLPs are about the same. Therefore, the differences in production levels are about the same in late stages of lactation and in early lactation, regardless of production Rolling Herd Average (RHA). In addition, higherproducing herds have their highest level of production in the second stage of lactation (51 to 100 days in milk), whereas this occurs in the first stage of lactation …

Kansas Agricultural Experiment Station Research Reports

Three experiments, using 344 pigs, were conducted to evaluate the influence of β-glucan (MacroGardâ„¢-S) on neutrophil and macrophage function, resistance to Streptococcus suis challenge, and growth performance in weanling pigs. β-glucan, when fed at inclusion rates of .05 and .1 %, did not influence neutrophil or macrophage function or increase overall growth performance. Similarly, .025% β-glucan did not alter neutrophil or macrophage bactericidal activity or production of superoxide anion. However, diets containing.025% β-glucan increased average daily gain, average daily feed intake, and pigs weights and decreased plasma haptoglobin levels on d 21. Unfortunately, pigs fed a diet containing .025% that …

Strategies For Small Dairy Farmers To Be Profitable And Competitive In The Future (1994), B. Cropp Jan 1994

Strategies For Small Dairy Farmers To Be Profitable And Competitive In The Future (1994), B. Cropp

Kansas Agricultural Experiment Station Research Reports

Profitable dairying will not become any easier in the future. Farm level milk prices will continue to be volatile. The government will not provide additional price or income support to dairies. Long-run milk prices will be either flat or perhaps even trending slightly lower. Average annual milk prices will be in the range of $12.00 to $13.25 per hundredweight. Dairy producers must be able to generate adequate net income at these milk price levels. Smaller dairy operators need to find means of being cost competitive with the larger operators. Without question, smaller producers can be profitable in the decade ahead …

The Effect Of Sodium Bicarbonate Level On Rumen Metabolism In Steers With Induced Subacute Acidosis, S.A. Shuey, Robert T. Brandt Jr., S.M. Gramlich Jan 1994

The Effect Of Sodium Bicarbonate Level On Rumen Metabolism In Steers With Induced Subacute Acidosis, S.A. Shuey, Robert T. Brandt Jr., S.M. Gramlich

Kansas Agricultural Experiment Station Research Reports

Sodium bicarbonate at 1 or 2% of dry matter intake was evaluated as a means of alleviating subacute acidosis, using six fistulated Holstein steers in a controlled acidosis challenge model. Steers were feed challenged by withholding an evening feeding and then feeding 2.5% of BW for two consecutive mornings. Postchallenge rumen pH for control steers (no sodium bicarbonate) was lower (P<.05) than for steers fed either 1% or 2% sodium bicarbonate, which were similar to each other. Hours below pH 5.6 were less (P<.01) postchallenge for steers fed sodium bicarbonate and w ere similar between the 1 and 2% levels. Although sodium bicarbonate reduced ruminal pH hours below 5.6, it did not appear to alter concentrations of volatile fatty acids or lactate in acidotic steers. Sodium bicarbonate appears to be beneficial in managing subacute acidosis in situations where wide intake fluctuations are common or expected.

Effect Of Grain Content On The Nutritive Value Of Whole-Plant Corn Silage, R.N. Jr. Sonon, B.S. Dalke, D.L. Holthaus, L. Pfaff, K.K. Bolsen, Matthew A. Young

Kansas Agricultural Experiment Station Research Reports

This experiment was conducted to determine the effect of grain content on the nutritive value of corn silage. Whole-plant silage dry matter (DM) increased, whereas neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents decreased as the level of grain increased from 0 to 65% in the reconstituted, whole-plant, corn silages. Using sheep as a model, voluntary DM intake and DM and organic matter (OM) digestibility increased, but crude protein (CP) and ADF digestibilities decreased linearly as grain content increased from 0 to 52.5%. Our results indicate that the optimum level of grain in whole-plant corn silage to maximize …

Dormant, Tallgrass-Prairie Forage: Influence Of Ruminal Degradable Protein On Intake By Beef Cows And Fermentation Characteristics, H.H. Koster, R.C. Cochran, E.S. Vanzant, G. St Jean, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

Five ruminally and duodenally fistulated Angus x Hereford cows were fed dormant tallgrass-prairie forage ad libitum to monitor intake and fermentation responses associated with providing increasing amounts of supplemental ruminal degradable protein (RDP). The RDP was provided from sodium caseinate and infused intraruminally immediately before feeding forage. Levels of RDP were 0, 180, 360, 540, and 720 g/d. Maximal intake of dormant, tallgrass-prairie forage occurred with provision of 540 g RDP/d. Ruminal dry matter fill declined with increasing level of RDP infusion. Increasing supplmentation of RDP generally improved ruminal fermentation characteristics.

Kansas Agricultural Experiment Station Research Reports

Lactic acid sprays effectively reduce the microbial load on both carcasses and subprimal cuts. Lactic acid decontamination of subprimals appears to carry through to retail cuts during display. Because of recontamination during fabrication, treating subprimals may be more effective than treating carcasses. This information will allow us to identify the most critical control points at which to employ decontamination practices designed to reduce the incidence of pathogenic bacteria and extend shelf life.

However, these methods fail to characterize the changing response of tissue accretion to dietary amino acids as body weight increases. For this reason, growth modeling was used to characterize the response to digestible lysine in two experiments (114 gilts each) from 80 to 160 lb and 160 to 300 lb, respectively. Corn-soybean meal diets were formulated to assure that lysine (.54 to 1.04% and .54 to .94% digestible lysine for Exp 1 and 2, respectively) was the first limiting …

A total of 100 weanling pigs with an average initial body wt of 11.8 lb and average age of 17 d was used in a 38-d growth assay to determine the effect of castration on growth performance of nursery pigs. All pigs were fed the same Phase I, II, and III diets formulated to 1.6, 1.4, and 1.35% lysine, respectively. Data indicated no differences in growth performance between intact males and barrows in the first 38 d postweaning (12 to 48 lb).; Swine Day, Manhattan, KS, November 17, 1994
