Influence Of Dietary Niacin On Finishing Pig Performance And Meat Quality (2000), D E. Real, J C. Woodworth, M J. Webster, B W. James, E Alonso, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband, John A. Unruh, Joel M. Derouchey, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

One hundred forty-four finishing pigs were used to determine the influence of added dietary niacin on their growth performance and meat quality. Gilts grew slower, ate less, and were more efficient than barrows for the entire growth performance period. Increasing dietary niacin levels to 25 g/ton increased ADG in gilts for the first 25 days, but decreased ADG for barrows. No other interactions occurred. From d 25 to 62, ADFI tended to increase for pigs fed up to 100 g/ton niacin, whereas pigs fed 500 g/ton niacin ate less. Dietary niacin level did not significantly affect carcass yield or quality …

Determination Of The Amount Of Wet Corn Gluten Feed To Include In Diets For Lactating Dairy Cows (2000), M. J. Vanbaale, Michael V. Scheffel, Evan C. Titgemeyer, R.U. Lindquist

Kansas Agricultural Experiment Station Research Reports

Twenty-four multiparous Holstein cows were used in six 4x4 Latin squares with 28- day periods to determine inclusion rates for wet corn gluten feed (WCGF) in diets for lactating dairy cows. Cows were housed in a tie-stall barn and fed diets to meet or exceed NRC (1989) nutrient requirements. Experimental treatments were 1) control, 2) WCGF constituting 20%, 3) WCGF constituting 27.5%, and 4) WCGF constituting 35% of the diet dry matter. Cows fed WCGF consumed more dry matter (P<0.01) and produced more (P<0.001) milk, energy-corrected milk, and fat-corrected milk than cows fed the control diet. Dry matter intakes were 58.9 lb/day for control and 60.2 lb/day for those cows consuming WCGF diets. Cows fed the control diet produced 83.2 lb/day of milk, whereas those fed WCGF diets produced 91.5 lb/day. Production efficiency was increased (P<0.001) on the WCGF diets. The percentage of fat in milk, total protein production, and milk urea nitrogen were higher (P<0.01) for cows fed WCGF diets than controls. Plasma glucose, total αamino nitrogen, urea nitrogen, and tryglycerides were similar between cows fed the control and WCGF diets. No differences occurred in percentages of protein, lactose, or solids-not-fat content, nor was somatic cell count affected by the addition of WCGF. Body weight and condition score were not affected by treatment. We conclude that WCGF is an excellent feed for lactating dairy cows when included in the diet at 20%, 27.5%, or 35% of the dry matter.; Dairy Day, 2000, Kansas State University, Manhattan, KS, 2000;

Raw Milk Quality: The Processor's Point Of View, Karen A. Schmidt

Kansas Agricultural Experiment Station Research Reports

Raw milk quality is important to the processor for many reasons, this quality can be assessed by several different tests. Quality tests are used to ensure that the raw milk meets legal USDA standards as well as some of the individual requirements of the processor. Although some quality tests can be done in a matter of minutes, others require up to several days to complete. Because milk quality deteriorates relatively quickly, it is important to concentrate on those tests that provide the greatest amount of information in the shortest time. This information then is extrapolated to assess the "actual raw …

Mastitis Management-Effective Methods To Reduce Somatic Cell Counts (2000), John F. Smith, Michael J. Brouk

Kansas Agricultural Experiment Station Research Reports

Mastitis is the most costly health concern in the dairy industry today. Annual losses have been estimated at $180 to 185 per cow. Based on this figure, annual losses for Kansas producers may exceed $15 million. Nationally, mastitis may cost the industry $1.8 billion annually. Although treatment and premature culling for clinical mastitis are costly, about two-thirds of the cost is associated with reduced milk production caused by subclinical mastitis. Effective mastitis control programs are necessary for the dairy industry today. Prevention of subclinical mastitis is the key to lowering the somatic cell counts (SCC). Elevated bulk tank SCC ( …

Flushing Sand-Laden Manure (2000), Joseph P. Harner, T.D. Strahm, James P. Murphy

Kansas Agricultural Experiment Station Research Reports

Sand can be handled successfully either in a scrape or flush system by developing handling systems that allow for the sand-laden manure to settle prior to the effluent entering a lagoon. The abrasiveness and density of sand create problems in handling the manure. Manure weighs about 60 lb/cu ft, whereas sand has a density of 120 lb/cu ft. Sand-laden manure will have an approximate density of 80 lb/cu ft, if 30% of the manure is sand. Because sand is heavier, it will not remain in suspension as long as manure and settles rapidly. Many problems associated with handling sand-laden manure …

Salmonella Dublin: A Threat To Dairy Heifer Survival And Future Performance (2000), D.G. Schmidt, D.P. Gnad, J.M. Sargeant, John E. Shirley

Kansas Agricultural Experiment Station Research Reports

Salmonella dublin is a bacterium that can have devastating effects in dairy herds. It is most deadly with calves that range in age from 10 days to 5 months. Salmonella dublin is shed from carrier animals through feces, milk, and colostrum and spread by oral ingestion. Clinical signs are not detected easily until after the infection is well established. Calves may suffer from septicemia, diarrhea, fatigue, and unthriftiness. Death is not an uncommon outcome of this disease. Clinical signs of infection in adults may range from none to enteritis or abortion. Combating the disease requires an awareness of the disease, …

Total Blood Protein As An Indicator Of Colostral Sufficiency And Morbidity In Dairy Calves (2000), D.G. Schmidt, D.P. Gnad, J.M. Sargeant, John E. Shirley

Kansas Agricultural Experiment Station Research Reports

Total blood protein measured in calves between 1 and 7 days of age is a good indicator of the sufficiency of colostral intake and level of immunity passed to the calf. This measurement can be used to improve calf management strategies and thereby calf performance. Total blood protein concentrations are associated with immunoglobulin absorption in the neonatal calf, which can impact calf morbidity and mortality. Blood protein>5.5 g/dl indicates sufficient immunoglobulin absorption, and blood protein <5.0 g/dl indicates insufficient absorption. Insufficient immunoglobulin absorption increases the risk of calf morbidity and mortality. The dry cow health program, proper collection, and management of colostrum help ensure that quality colostrum is available for the newborn calf. Proper colostrum administration and low-stress calf management also ensure maximal immunoglobulin absorption. Timing of colostral intake affects total blood protein concentrations. The calf's ability to absorb immunoglobulins is reduced significantly 12 hr after birth. Therefore, it is critical to administer colostrum during the first few hours of life. Total blood protein can be used to determine if the calf has absorbed sufficient immunoglobulins from the colostrum.; Dairy Day, 2000, Kansas State University, Manhattan, KS, 2000;

Antibiotic Versus Nonantibiotic Products For The Treatment Of Papillomatous Digital Dermatitis (Hairy Heel Wart) In Dairy Cattle (2000), J.M. Sargeant, D.P. Gnad, J. Isch, H. Bathina

Kansas Agricultural Experiment Station Research Reports

A field trial was conducted to compare oxytetracycline to three nonantibiotic therapies using bandage protocols for the treatment of hairy heel warts. Affected feet were bandaged for 4 days with either of the four products. Over a 28-day period following bandage removal, heel warts on 44 cows (11 per treatment group) were evaluated based on size, degree of pain, color, and lesion appearance. No differences were detected among treatments, suggesting that nonantibiotic therapies used in bandage protocols may be as effective as oxytetracycline.; Dairy Day, 2000, Kansas State University, Manhattan, KS, 2000;

Economics Of Cooling Cows To Reduce Seasonal Variation In Peak Milk Production (2000), Kevin C. Dhuyvetter

Kansas Agricultural Experiment Station Research Reports

The economic impact of cooling cows to reduce the seasonal variation in peak milk production was estimated using researchbased lactation curves and peak production numbers for a commercial dairy operation in Kansas. Reducing the seasonal drop in peak production that occurs in the late summer and fall months by 29% or more is profitable for second or higher lactation cows. This reduction represents an increase in total milk production over the entire lactation of slightly over 1% and an increase in the average annual peak production of only 1 lb. This indicates that achieving at least the breakeven level for …

Monensin: An Overview Of Its Application In Lactating Dairy Cow Diets (2000), J.M. Defrain, John E. Shirley

Kansas Agricultural Experiment Station Research Reports

The efficiency of feedstuff utilization by ruminal microorganisms and the cow's genetic ability to convert feed nutrients into milk and milk components are major factors that influence the profitability of a dairy herd. Monensin's ability to modify the movement of ions across biological membranes leads to alterations in bacterial populations and subsequent changes in the proportion of volatile fatty acids produced during ruminal fermentation. Manipulating ruminal microbial populations with ionophores has the potential to improve performance by reducing ketosis, acidosis, and bloat and increasing digestive efficiency. Monensin improves fiber digestion by preventing suboptimal ruminal pH, enhances amino acid use by …

Effect Of Level Of Surface-Spoiled Silage On Teh Nutritive Value Of Corn Silage-Based Rations, L.A. Whitlock, M.K. Siefers, Ronald V. Pope, B.E. Brent

Kansas Agricultural Experiment Station Research Reports

Twelve ruminally cannulated crossbred steers were used to determine the effect of level of surface spoilage in corn silage-based rations on dry matter (DM) intake and nutrient digestibilities. Irrigated corn was harvested at the 80% milkline stage of maturity and ensiled in pilot-scale bunker silos, which were 3 ft in depth, and a 9-ft-diameter AgBag®. After 90 days, the bunkers were sealed with a single sheet of polyethylene, and this silage was designated "spoiled". The silage in the AgBag was designated "normal". The four rations contained 90% silage and 10% supplement (DM basis), and the proportions of silage in the …

Intake And Performance Of Dairy Cows Fed Wet Corn Gluten Feed During The Periparturient Period (2000), A.F. Park, J.M. Defrain, M. J. Meyer, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

Eight primiparous and nine multiparous Holstein cows were used in a randomized block design to determine the effect of wet corn gluten feed in the diet during the last 21 days of gestation on dry matter intake and early postpartum performance. Multilactation cows fed wet corn gluten feed maintained a higher dry matter intake and intake as a percentage of body weight during the last week before calving than cows fed the control diet. First-lactation cows fed wet corn gluten feed consumed less dry matter, both total and as a percentage of body weight, across calving than first-lactation cows fed …

Relationship Among Concentrations Of Milk Urea Nitrogen And Plasma Urea Nitrogen And Feeding Time (2000), E.E. Ferdinand, M. J. Meyer, A.F. Park, M. J. Vanbaale

Kansas Agricultural Experiment Station Research Reports

Eight Holstein cows were used to determine the relationship among milk urea nitrogen (MUN), plasma urea nitrogen (PUN), and feeding time. We first established that MUN concentrations were similar in concentration among quarters by comparing milk samples from each quarter just before milking. In order to determine if collecting a sample of milk from a quarter influenced the MUN in samples taken later, samples were obtained from the right front quarter (RF) at 2, 4, 6, and 8 hr after the AM milking and from the left front quarter (LF), right rear (RR), and left rear (LR) at 4, 6, …

Factors Affecting Dry Matter Intake By Lactating Dairy Cows (2000), John F. Smith, Michael J. Brouk

Kansas Agricultural Experiment Station Research Reports

Feed intake is the single most critical factor of dairy production, and performance of dairy cattle can be enhanced or hindered by environmental factors that affect it. These environmental factors can by divided into physical and climatic conditions. On modern dairies, the physical factors may be of more concern. Modern facilities provide the cow with protection from the natural elements. However, these same facilities can enhance or hinder dry matter intake. Facilities should provide adequate access to feed and water, a comfortable resting area, and adequate protection from the natural elements. Critical areas of facility design related to feed intake …

Keeping Cows Cool (2000), John F. Smith, Joseph P. Harner, Michael J. Brouk

Kansas Agricultural Experiment Station Research Reports

Heat stress occurs when a dairy cow's internal heat load is greater than her capacity to lose unwanted heat to the environment. Effects of heat stress include: increased respiration rate, increased water intake, increased sweating, decreased dry matter intake, slower rate of feed passage, decreased blood flow to internal organs, decreased milk production, and poor reproductive performance. Lower milk production and reproductive performance cause economic losses to dairy producers. The ordered priorities for reducing heat are: increasing water availability; providing shade in the housing areas (both dry and lactating cows) and holding pen; reducing walking distance to the parlor; reducing …

Anestrus In Lactating Dairy Cows Before Ovulation Synchronization (2000), J.A. Cartmill, S.E. Zarkouny, Hensley, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

The incidence of anestrus in dairy cattle prior to first inseminations carried out after a minimum of 60 days postpartum ranged from 4 to 58% in first-lactation cows and 14 to 50% in older cows. Dairy cows with more days in milk, older than 2 years, and in better body condition (probably reflective of greater postpartum dry matter intakes) were more likely to cycle than thinner cows. Cows that were not cycling before the first week of insemination conceived at lower rates and took longer to become pregnant.; Dairy Day, 2000, Kansas State University, Manhattan, KS, 2000;

Embryo Survival In Lactating Dairy Cows (2000), J.A. Carmill, S.E. Zarkouny, B.A. Hensley, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

Rates of embryo survival in lactating dairy cows were assessed in three separate studies. Based on pregnancy diagnoses 27 to 29 days after timed inseminations, survival to days 40 to 50 or day 57, depending on the study, varied from 9 to 88% in cows that were not cycling before insemination compared to 57 to 90% in cows that were cycling. Previously anestrous cows had lower rates of survival. In one study, supplementing cows with progesterone before insemination improved embryo survival.; Dairy Day, 2000, Kansas State University, Manhattan, KS, 2000;

Effects Of Frequency Of Supplementation On Performance Of Beef Cows Grazing Winter Pasture, C.G. Farmer, R.C. Cochran, D.D. Simms, E.A. Klevesahl, T.A. Wickersham

Kansas Agricultural Experiment Station Research Reports

One hundred twenty spring-calving Hereford x Angus cows grazing low-quality tallgrass-prairie forage during the winter of 1998 were fed a 43% crude protein supplement 2, 3, 5, or 7 days a week. Supplement was fed at 4 lb/head daily to cows supplemented daily. The other cows still received 28 lb per week but divided equally among feedings. Cumulative performance (measured by changes in body condition score and body weight) was slightly better with increased supplementation frequency. However, the magnitude of differences in body condition and body weight changes, even for the most extreme treatment comparisons, were relatively small.

Effects Of Frequency Of Supplementation On The Intake And Digestion Of Low-Quality Forage By Beef Steers, C.G. Farmer, R.C. Cochran, D.D. Simms, E.A. Klevesahl, T.A. Wickersham

Kansas Agricultural Experiment Station Research Reports

A 43% CP (dry basis) supplement was fed to 16 ruminally fistulated steers on 2, 3, 5, or 7 days a week. Supplement was offered at .36% BW (dry basis) daily for steers that received supplement every day. For other treatments, the same amount of supplement was split equally among supplementation events. Forage intake and digestibility increased with increasing supplementation frequency. However, the difference in forage intake tended (cubic, P=.07) to be most prominent for the two extremes; the 3- and 5-days-a-week treatments tended to be similar. Forage intake for steers supplemented on 2 days a week decreased on the …

Effects Of Cattle Grazing Crop Residues On Soil Bulk Density, R.K. Taylor, John W. Slocombe

Kansas Agricultural Experiment Station Research Reports

Effects of cattle grazing on soil bulk density were measured at two sites in central Kansas. Samples were taken at depths of 0 to 3 in. and 3 to 6 in. from grazed and ungrazed areas at five locations in each field. No statistical difference (P>0.01) between bulk densities of the two areas occurred at the 3 to 6 in. depth for either site. However, soil in the grazed areas had significantly higher (P<0.01) bulk density than that in the ungrazed areas at the 0 to 3 in. depth at both sites.

Effects Of Grazing System On Performance Of Cow-Calf Pairs Grazing Bermudagrass Pastures Interseeded With Wheat And Legumes, Lyle W. Lomas, Joseph L. Moyer, K.P. Coffey, George A. Milliken

Kansas Agricultural Experiment Station Research Reports

A total of 96 fall-calving cows and 64 calves grazed bermudagrass interseeded with wheat and legumes during 1996, 1997, and 1998 in either a continuous or rotational system stocked at equal rates. Legume cover, available forage dry matter, residual hay production, gains of cows and calves grazing wheat interseeded into bermudagrass, and gains of cows grazing bermudagrass interseeded with legumes were measured. Grazing system had no effect on legume cover, available forage dry matter, gains of cows and calves (wheat phase), and gains of cows (legume phase); however, rotationally grazed pastures produced more residual hay than those grazed continuously.

Alfalfa Hay Levels In Limit-Fed, High-Energy, Growing Diets For Beef Steers, Sean P. Montgomery, J.J. Sindt, T.B. Farran, H.J. Labrune, R.D. Hunter, James J. Higgins, T.A. Nutsch, R.A. Stock, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

One hundred sixty-four crossbred beef steers were used in a 102-day growing study to determine optimum levels of alfalfa hay in limit-fed, high-energy, growing diets. Diets contained steam-flaked corn and 40% Sweet Bran® brand wet corn gluten feed (dry matter basis) with 0, 10, or 20% ground alfalfa hay. A fourth diet containing steam-flaked corn (no Sweet Bran) and 20% ground alfalfa hay was used as a control. Average daily gains and feed efficiencies in the growing phase were greater (P<.05) for cattle fed no alfalfa than for cattle fed the control, 10% alfalfa, or 20% alfalfa diets. Steers fed the control and 20% alfalfa diets had increased rates of dry matter intake (P<.05) compared to those fed no alfalfa. At the end of the growing phase, all cattle were placed on a common finishing diet and fed for 101 days. Dry matter intakes during the finishing phase for cattle previously fed no alfalfa were numerically less than intakes for cattle fed other diets and significantly less than intakes for cattle previously fed the control diet. Feed efficiencies were greater for cattle previously fed 20% alfalfa diets than those fed the control diet (P<.05). Average daily gains did not differ (P>.40) among diets during the finishing phase.
