Tower Tank Valve Flushing System For Dairy Facilities (1998), Joseph P. Harner, James P. Murphy, John F. Smith Jan 1998

Tower Tank Valve Flushing System For Dairy Facilities (1998), Joseph P. Harner, James P. Murphy, John F. Smith

Kansas Agricultural Experiment Station Research Reports

Flushing characteristics of a tower tank valve flushing system with a 12-inch-diameter manual valve were determined. Data were obtained using the outside cow alleys in a fourrow freestall barn. The alleys were 12 ft wide and 420 ft long with a 2% slope. The average flow rate exceeded 8,000 gallons per minute (gpm) when the average head was above 30 ft and the manual valve opened 80 degrees. Opening the valve to 90 degrees increased the flow rate to over 9,700 gpm. The velocity of the flushing wave was 8.5 fpm with a flow depth of 3.5 in. The estimated …

Assessment Of Mastitic Infection In Bovine Milk Using Atp Bioluminescence (1998), M. J. Meyer, D. Sukup, Karen A. Schmidt, John E. Shirley Jan 1998

Assessment Of Mastitic Infection In Bovine Milk Using Atp Bioluminescence (1998), M. J. Meyer, D. Sukup, Karen A. Schmidt, John E. Shirley

Kansas Agricultural Experiment Station Research Reports

Few choices exist for a mobile, rapid, and nonsubjective assessment of mastitic infection in bovine milk. This project evaluated the effectiveness of using the Biotrace® raw milk quality ATP bioluminescence assay to serve this role. Milk samples with various somatic cell counts (13,000 - 2,500,000) and signs of mastitic infection were obtained from the Kansas State University Dairy Teaching and Research Center. Within 24 hr, raw milk samples were evaluated for microbial numbers and relative light units (RLU). The printed test procedure was modified to evaluate accurately clinical mastitic milk samples. As somatic cell count increased in raw milk, the …

Cooling Rate And Storage Temperature Affect Bacterial Counts In Raw Milk (1998), I.M Cox, S. Adapa, Karen A. Schmidt Jan 1998

Cooling Rate And Storage Temperature Affect Bacterial Counts In Raw Milk (1998), I.M Cox, S. Adapa, Karen A. Schmidt

Kansas Agricultural Experiment Station Research Reports

Raw milk was obtained from the K-State Dairy Teaching and Research Center and evaluated for quality after being stored under various conditions. Results showed that as storage temperature increased from 35 to 45EF for 0 to 72 hr, total bacterial counts increased, whereas the titratable acidity and pH values remained fairly constant. Changing the cooling rate affected microbial numbers. Cooling to 40EF within 30 versus 120 min reduced microbial counts by 50%. Finally, the preincubation test was shown to be an effective method to document possible psychrotrophic contamination before the milk arrives at the processing facility.; Dairy Day, 1998, Kansas …

Effects Of Particle Size And Mixing Time On Uniformity And Segregation In Pig Diets (1998), N Amornthewaphat, Keith C. Behnke, Joe D. Hancock Jan 1998

Effects Of Particle Size And Mixing Time On Uniformity And Segregation In Pig Diets (1998), N Amornthewaphat, Keith C. Behnke, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

Diet uniformity, as represented by the coefficient of variation (CV), improved as mixing time was increased from 15 to 120 seconds and(or) com particle size was decreased from 1,200 to 400 ~m. Segregation occurred during free-fall, and the coarser particle sizes resulted in greater segregation than the finer particle sizes. Thus, reducing particle size of the cereal grain in swine diets not only improves efficiency of growth (as demonstrated in numerous KSU Swine Day Reports) but also decreases mix time needed for adequate blending and the likelihood of segregation during handling, storage, and delivery of diets to feeders.; Swine Day, …

Effects Of Conditioners (Standard, Long Term, And Expander) On Pellet Quality And Growth Performance In Nursery Pigs (1998), S L. Johnston, Robert H. Hines, C A. Maloney, S L. Traylor, S P. Sorrell, Joe D. Hancock, Keith C. Behnke Jan 1998

Effects Of Conditioners (Standard, Long Term, And Expander) On Pellet Quality And Growth Performance In Nursery Pigs (1998), S L. Johnston, Robert H. Hines, C A. Maloney, S L. Traylor, S P. Sorrell, Joe D. Hancock, Keith C. Behnke

Kansas Agricultural Experiment Station Research Reports

In our first experiment, digestibilities for DM, N, and GE were greater and F/G was better for pigs fed pelleted diets than for pigs fed meal diets. However, we observed no advantages in ADG or F/G with long-term conditioning. In a second experiment, pelleting once again improved nutrient digestibility and F/G. Expander conditioning improved digestibilities of DM, N, and GE but not growth performance compared to standard conditioning.; Swine Day, Manhattan, KS, November 19, 1998

Effects Of Source And Level Of Added Chromium On Growth Performance And Carcass Characteristics Of Growing-Finishing Pigs (1998), P R. O'Quinn, J W. Smith Ii, K Q. Owen, S A. Blum, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband Jan 1998

Effects Of Source And Level Of Added Chromium On Growth Performance And Carcass Characteristics Of Growing-Finishing Pigs (1998), P R. O'Quinn, J W. Smith Ii, K Q. Owen, S A. Blum, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

A growth trial \vas conducted to evaluate the effects of added chrOlniu111 nicotinate (CrNic) on growth performance and carcass composition of growing-finishing pi.gs (80 to 230 lb) and to compare 200 ppb of CrNic and chromium picolinate (CrPic). Few statistical responses were observed for growth performance, carcass characteristics, or serum chemistry profiles. These data suggest no beneficial responses to supplemental chromium in diets for growing-finishing barrows and gilts.; Swine Day, Manhattan, KS, November 19, 1998

Effects Of Diet Manipulation On Growth Performance, Carcass Characteristics, And Meat Quality Of Intact Male Pigs (1998), C A. Maloney, Robert H. Hines, H Cao, J S. Park, Joe D. Hancock Jan 1998

Effects Of Diet Manipulation On Growth Performance, Carcass Characteristics, And Meat Quality Of Intact Male Pigs (1998), C A. Maloney, Robert H. Hines, H Cao, J S. Park, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

Castrates were predictably less efficient, had greater ADFI, and tended to have more BF than contemporary boars. Castration decreased detection of boar taint, but alterations of dietary CP, pH, and antimicrobial level from 225 to 276 lb had no effect on sensory panel perception of odor from fat of intact males.; Swine Day, Manhattan, KS, November 19, 1998

Influence Of Chop Location On Boneless Pork Loin Quality (1998), A T. Waylan, R C. Johnson, John A. Unruh Jan 1998

Influence Of Chop Location On Boneless Pork Loin Quality (1998), A T. Waylan, R C. Johnson, John A. Unruh

Kansas Agricultural Experiment Station Research Reports

Eighty-two boneless pork loins were used to examine the effects of chop location on longissimus muscle quality. The highest quality chops came from the posterior end. They had the lowest Warner-Bratzler shear value (most tender), highest cooking yield, and a high pH and percent extractable lipid. Visual and instrumental data suggested that the most posterior chop was lighter colored and had the highest degree of marbling. Color, firmness, and marbling evaluations were similar in the central posterior section of the loin. This suggests that this section was very uniform in visual pork quality. The anterior portion of the loin was …

Conditions During Expander Processing Of Soybean Meal And Raw Soybeans Affect Nutrient Digestibility In Finishing Pigs (1998), S L. Traylor, Robert H. Hines, N Amornthewaphat, S L. Johnson, P Sorrell, Joe D. Hancock, Keith C. Behnke Jan 1998

Conditions During Expander Processing Of Soybean Meal And Raw Soybeans Affect Nutrient Digestibility In Finishing Pigs (1998), S L. Traylor, Robert H. Hines, N Amornthewaphat, S L. Johnson, P Sorrell, Joe D. Hancock, Keith C. Behnke

Kansas Agricultural Experiment Station Research Reports

Expander processing improved nutrient digestibility in diets with soybean meal and raw soybeans. Furthermore, with 600 psi cone pressure (20 k Wh/tonon ofspecific energy input), the diets with raw soybeans had equal or greater digestibility of nutrients compared to the soybean meal-based control diet.; Swine Day, Manhattan, KS, November 19, 1998

Expander Processing Conditions Affect Nutrient Digestibility In Finishing Pigs Fed Corn-, Sorghum-, Wheat-, And Wheat Midds-Based Diets (1998), S L. Traylor, Robert H. Hines, D J. Lee, S L. Johnston, P Sorrell, Joe D. Hancock, Keith C. Behnke Jan 1998

Expander Processing Conditions Affect Nutrient Digestibility In Finishing Pigs Fed Corn-, Sorghum-, Wheat-, And Wheat Midds-Based Diets (1998), S L. Traylor, Robert H. Hines, D J. Lee, S L. Johnston, P Sorrell, Joe D. Hancock, Keith C. Behnke

Kansas Agricultural Experiment Station Research Reports

Expander processing of corn-, sorghum-, wheat-, and wheat midds-based diets improved nutrient digestibility in growing pigs and, thus, the apparent digestible energy concentration in the diets. This new feed manufacturing technology was especially beneficial to the feedstuff with the highest fiber content (i.e., wheat midds).; Swine Day, Manhattan, KS, November 19, 1998

Effects Of Whole Grain And Distillers Dried Grains With Solubles From Normal And Heterowaxy Endosperm Sorghums On Growth Performance, Nutrient Digestibility, And Carcass Characteristics Of Finishing Pigs (1998), B W. Senne, Robert H. Hines, D W. Dean, I Mavromichalis, J R. Froetschner, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

No differences occurred in ADG, ADFI, F/G, digestibilities of DM and GE, dressing percentage, 10th rib fat depth, or fat free lean index in pigs fed normal vs heterowaxy sorghums. As anticipated, with the greater fiber and lower energy in distillers dried grains with solubles (DDGS) than the parent cereal grains, ADG and digestibilities of DM and GE were lower and F/G was worse for pigs fed DDGS. However, the energy value of the DDGS was affected less adversely when heterowaxy sorghum was used for fermentation to ethanol.; Swine Day, Manhattan, KS, November 19, 1998

Kansas Agricultural Experiment Station Research Reports

Results of these studies suggest that experimental high molecular weight, whey protein concentrate can be an effective replacement for spray-dried animal plasma in diets for weanling pigs. Increasing spray-dried animal plasma improved ADG and ADFI quadratically, with the maximum response observed with 2.5% in 21-d-old pigs or 5.0% in 12-d-old pigs. The specialty whey protein concentrate fed from d 0 to 14 after weaning resulted in similar responses as spray-dried animal plasma fed during the same period and may be an effective alternative.; Swine Day, Manhattan, KS, November 19, 1998

Effects Of Increasing Pantothenic Acid On Growth Performance Of Segregated Early-Weaned Pigs (1998), G S. Grinstead, R Stott, Robert D. Goodband, Jim L. Nelssen, Michael D. Tokach, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

We conducted a 28-d experiment to evaluate effects of increasing dietary pantothenic acid on growth performance of segregated early-weaned pigs. Pigs (initially 8.8 ± 2.21b and 11 ± 2 d of age) were fed a control diet (no added pantothenic acid) or the control diet with 30, 60, and 120 ppm of added pantothenic acid. Increasing pantothenic acid increased ADG and ADFI linearly from dO to 14 after weaning. However, from d 14 to 28 after weaning, pigs fed 60 mg/kg of added pantothenic acid tended to have the greatest ADG and ADFI. For the cumulative period (d 0to 28 …

Kansas Agricultural Experiment Station Research Reports

Three experiments were conducted to determine the effects of replacing lactose with sucrose and molasses in simple and complex diets for nursery pigs. In general, complex diets supported greater growth performance than simple diets, and added lactose and sucrose gave greater efficiency of growth than diets without added sugars. Comparisons among sugar sources indicated that lactose, sucrose, and molasses were utilized equally well by weanling pigs.; Swine Day, Manhattan, KS, November 19, 1998

Apparent Ileal Digestiblity Of Amino Acids And Digestible And Metabolizable Energy Values For Conventional Soybean Meal Or Dry Extruded-Expelled Soybean Meal For Swine (1998), J C. Woodworth, P R. O'Quinn, D A. Knabe, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen Jan 1998

Apparent Ileal Digestiblity Of Amino Acids And Digestible And Metabolizable Energy Values For Conventional Soybean Meal Or Dry Extruded-Expelled Soybean Meal For Swine (1998), J C. Woodworth, P R. O'Quinn, D A. Knabe, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

We conducted two experiments to determine the apparent ileal digestibility of amino acids and digestible energy (DE) and metabolizable energy (ME) values for conventionally processed, solvent-extracted soybean meal (SBM) compared to dry-extruded-expelled SBM with or without soy hulls. Apparent ileal digestibility of crude protein and lysine and DE and ME values were greater in either extruded-expelled SBM compared to the conventionally processed SBM. No differences occurred in apparent digestibility of amino acids or energy values between extruded-expelled SBM with hulls and that without hulls. These results suggest that the dry extrusion followed by expeller processing of soybeans results in a …

Effects Of Branched Chain Amino Acids On Sow And Litter Performance (1998), S A. Moser, J A. Loughmiller, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

Three hundred-six sows were used to evaluate effects of the interrelationship among valine, isoleucine, and leucine on sow and litter performance. Eight dietary treatments were arranged as a 2x2x2 factorial with two levels of valine (.80 and 1.20%), isoleucine (.68 and 1.08%), and leucine (1.57 and 1.97%). Litter weaning weight, litter weight gain from d 2 to weaning, and sow backfat loss increased as dietary valine increased but were not affected by dietary isoleucine or leucine. Increasing dietary valine, isoleucine, or leucine did not affect milk fat, DM, CP, or lactose. These results confirm the importance of dietary valine for …

Kansas Agricultural Experiment Station Research Reports

Compared to a corn-soybean meal control, added-fat from tallow, soybean oil, and dry-extruded whole soybeans (DEWS) improved ADG, F/G, and digestibility of DM and N. Feeding tallow increased belly firmness but also increased backfat thickness compared to diets with soy oil and DEWS. Comparisons among soybean genotypes indicated that high oleic acid soybeans supported greater growth performance than soybeans with high palmitic acid content. However, soybean genotype had no effect on carcass or meat quality measurements.; Swine Day, Manhattan, KS, November 19, 1998
