Effects Of Supplemental Degradable Intake Protein On Intake And Digestibility Of Bermuda Hay, C.P. Mathis, R.C. Cochran, J.S. Heldt, B.C. Woods, Gerald L. Stokka, K. C. Olson, Evan C. Titgemeyer Jan 1998

Effects Of Supplemental Degradable Intake Protein On Intake And Digestibility Of Bermuda Hay, C.P. Mathis, R.C. Cochran, J.S. Heldt, B.C. Woods, Gerald L. Stokka, K. C. Olson, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

A study with 16 ruminally fistulated beef steers fed Bermuda hay ad libitum showed that the intake and digestibility of hay was not influenced by increasing levels of supplemental degradable intake protein (DIP). However, the hay used in this study was of medium quality; lower quality Bermuda hay with lower CP may respond to supplemental DIP.

Predicting Voluntary Forage Intake In Cattle, C.A. Bandyk, R.C. Cochran Jan 1998

Predicting Voluntary Forage Intake In Cattle, C.A. Bandyk, R.C. Cochran

Kansas Agricultural Experiment Station Research Reports

A large database was compiled of forage intake observations published during the past 20 years. Inputs included a wide range of factors believed to be related to voluntary intake. An analysis was designed to pinpoint which feed and animal characteristics were most valuable in predicting voluntary intake across a range of feeding situations and to compare the ability of different models to predict intake. Results emphasized the complexity of intake prediction. A wide range was evident in the variables included in the optimal models for predicting intake within different data subsets. In many cases, we observed that ratios between feed …

Effects Of Various Carbohydrate Sources On The Utilization Of Low-Quality Tallgrass-Prairie Hay In Continuous Culture, J.S. Heldt, R.C. Cochran, C.P. Mathis, Evan C. Titgemeyer, Tiruvoor G. Nagaraja Jan 1998

Effects Of Various Carbohydrate Sources On The Utilization Of Low-Quality Tallgrass-Prairie Hay In Continuous Culture, J.S. Heldt, R.C. Cochran, C.P. Mathis, Evan C. Titgemeyer, Tiruvoor G. Nagaraja

Kansas Agricultural Experiment Station Research Reports

We evaluated the effects of supplemental carbohydrate sources on the utilization of low- quality forage in continuous "artificial rumen" culture. Providing readily digestible carbohydrates (starch, glucose, and fiber) did not improve total diet digestion. In fact, starch and glucose depressed fiber digestion. Response to other simple sugars was variable.

Milking Two Or Five Times Daily In The Presence Of A Cow’S Own Nonsuckling Calf Fails To Prolong Postpartum Anovulation, G.C. Lamb, K. E. Thompson, J.S. Heldt, C.A. Löest, Jeffrey S. Stevenson Jan 1998

Milking Two Or Five Times Daily In The Presence Of A Cow’S Own Nonsuckling Calf Fails To Prolong Postpartum Anovulation, G.C. Lamb, K. E. Thompson, J.S. Heldt, C.A. Löest, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

Three treatments were initiated at approximately 15 days after calving and continued for 4 weeks: 1) cows were suckled ad libitum by their calves (calf present [CP]); 2) calves were present but nonsuckling 24 hr/day and cows were milked twice daily (CR+2xM); 3) or same as CR+2xM but cows were milked five times daily (CR+5xM). Interval to the first postpartum ovulation was similar between CR+2xM and CR+5xM cows but about 2 weeks less than that in cows suckled ad libitum by their own calves. Cows in the CR+5xM treatment produced more milk than cows in the CR+2xM treatment, whereas only …

Site Of Semen Deposition And Fertility In Lactating Beef Cows Synchronized With Gnrh And Pgf2Α, G.C. Lamb, K. E. Thompson, K. Anderson, David M. Grieger, Timothy G. Rozell, Jeffrey S. Stevenson Jan 1998

Site Of Semen Deposition And Fertility In Lactating Beef Cows Synchronized With Gnrh And Pgf2Α, G.C. Lamb, K. E. Thompson, K. Anderson, David M. Grieger, Timothy G. Rozell, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

Our objective was to determine the effect of site of semen deposition on pregnancy rate in beef cows inseminated at a fixed time or after observed estrus. Cows were synchronized with a combination of gonadotropin-releasing hormone (GnRH) prostaglandin-F α (PGF). GnRH was injected 7 days before PGF (day 0; first of breeding season). The trial was conducted at two locations, one in Kansas (147 cows) and one in Colorado (313 cows). At each location, cows were assigned to be inseminated after observed estrus (ESTRUS-AI) or at a fixed time (TIMED-AI). Within these two groups, cows either were inseminated in the …

Comparison Of Fusobacterium Necrophorum Isolates From Liver Abscesses, Ruminal Walls, And Ruminal Contents Of Feedlot Cattle, Sanjeev K. Narayanan, O. Okwumabua, J. Staats, Richard D. Oberst, Tiruvoor G. Nagaraja, M. M. Chengappa Jan 1998

Comparison Of Fusobacterium Necrophorum Isolates From Liver Abscesses, Ruminal Walls, And Ruminal Contents Of Feedlot Cattle, Sanjeev K. Narayanan, O. Okwumabua, J. Staats, Richard D. Oberst, Tiruvoor G. Nagaraja, M. M. Chengappa

Kansas Agricultural Experiment Station Research Reports

DNA finger printing (restriction fragment length polymorphism analysis) was employed to genetically compare Fusobacterium necrophorum isolates of liver abscesses, ruminal wall, and ruminal contents from the same animal. Fusobacterium necrophorum isolates from liver abscesses were genetically identical to the corresponding isolates from the ruminal wall in eight of nine animals tested. This genetic similarity between the isolates supports the hypothesis that F. necrophorum in liver abscesses originates from the ruminal wall.

Microbial Evaluation Of Steam Pasteurization And Comparison Of Excision Versus Sponge Sampling Recovery, D.L. Retzlaff, S.A. Rueger, Randall K. Phebus, James L. Marsden, Curtis L. Kastner Jan 1998

Microbial Evaluation Of Steam Pasteurization And Comparison Of Excision Versus Sponge Sampling Recovery, D.L. Retzlaff, S.A. Rueger, Randall K. Phebus, James L. Marsden, Curtis L. Kastner

Kansas Agricultural Experiment Station Research Reports

The use of steam pasteurization (SPS400™; Frigoscandia, Bellevue, WA) as a viable commercial-scale intervention method to treat pre-rigor beef carcasses uniformly hasbeen evaluated for temperatures from 180E to 201 ÌŠF. Effectiveness at lower temperatures(minimum atmospheric temperature of 170 ÌŠF) has not been evaluated. Previous studies of steam pasteurization used excision sampling. However, the USDA-FSIS has suggested use of nondestructive sampling of chilled beef carcasses for generic Escherichia coli, so we compared excision and sponge sampling in a commercial slaughter facility. Twenty-eight beef carcasses were monitored to determine the effectiveness of steam pasteurization and to compare the two sampling methods. Total …

Prevalence, Antibiotic Susceptibility, And Genetic Diversity Of Salmonella, Campylobacter, And Escherichia Coli O157:H7 Collected At Four Kansas Beef Cattle Feedyards Over 13 Months, D.R. Hyatt, J.C. Galland, S. Crupper, L. Hawkins, N.V. Anderson, Gerald L. Stokka Jan 1998

Prevalence, Antibiotic Susceptibility, And Genetic Diversity Of Salmonella, Campylobacter, And Escherichia Coli O157:H7 Collected At Four Kansas Beef Cattle Feedyards Over 13 Months, D.R. Hyatt, J.C. Galland, S. Crupper, L. Hawkins, N.V. Anderson, Gerald L. Stokka

Kansas Agricultural Experiment Station Research Reports

Salmonella, Campylobacter, and Eschericia coli O157:H7 are important foodborne pathogens, but longitudinal studies of their prevalence in beef cattle feedyards have not been done. Our long- term study involved 24,556 samples taken from beef cattle feedyards found overall prevalence's of 4.87% for Salmonella, 20.1% for Campylobacter in hospital pen fecal samples, and 0.20% for E. coli O157:H7. Yard and pen differences (P<0.05) were detected. All 53 E. coli O157:H7 isolates were resistant to Talmicosin and Erythromycin, two antimicrobials used in food animal medicine. Their genetic diversity was high and did not indicate the presence of resident strains at the yards studied. Salmonella, Campylobacter, and E. coli O157:H7 were probably brought into the yards by shipments of new cattle. Many of these organismswere susceptible to antibiotics commonly used to treat beef cattle.

Soybean Hulls In Roughage-Free Diets For Limit-Fed Growing Cattle, C.A. Löest, D.J. Bindel, Evan C. Titgemeyer, James S. Drouillard, Dale A. Blasi Jan 1998

Soybean Hulls In Roughage-Free Diets For Limit-Fed Growing Cattle, C.A. Löest, D.J. Bindel, Evan C. Titgemeyer, James S. Drouillard, Dale A. Blasi

Kansas Agricultural Experiment Station Research Reports

Three hundred heifers (573 lb initial body weight) were used in a growing study to compare growth performance of cattle fed roughage-free diets comprised mainly of soybean hulls with that of cattle receiving roughage- and corn-based diets and to determine if cattle fed soybean hull-based diets would respond to supplemental methionine hydroxy analogue (MHA; a source of methionine), ruminally protected betaine, or concentrated separator by-product (CSB; a source of betaine). Treatments included 1) a roughage-based diet fed at 2.75% of body weight (ROUGH), 2) a corn-based diet fed at 1.5% of body weight (CORN1.5), 3) a corn- based diet fed …

Effects Of Ruminally Protected Choline And Dietary Fat On Performance Of Finishing Heifers, D.J. Bindel, R.H. Wessels, C.A. Loest, James S. Drouillard, Evan C. Titgemeyer Jan 1998

Effects Of Ruminally Protected Choline And Dietary Fat On Performance Of Finishing Heifers, D.J. Bindel, R.H. Wessels, C.A. Loest, James S. Drouillard, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

A 120-day finishing study utilizing 318 heifers (753 lb initial body weight) examined the effects of ruminally protected choline in diets with no tallow or 2 or 4% of supplemental tallow. Heifers were fed a finishing diet based on a mix of steam-flaked and dry- rolled corn; encapsulated choline (20, 40, or 60 g/head/day, supplying 5, 10 or 15 g choline/head/day) was top-dressed to the diet or not added. Dry matter intake decreased linearly with inclusion of fat (P<.05) but was not affected significantly by addition of choline. Daily gains also decreased linearly (P<.05) with fat addition. Choline supplementation increased gain (linear, P<.1; qua dratic, P<.05), with the greatest increase occurring for the first 20 g increment encapsulated choline/day. Likewise, feed efficiency improved (P<.1) with supplemental choline. Again, the greatest response occurred for the first 20 g/day. Kidney, pelvic, and heart fat and yield grade both increased linearly (P<.1) with fat supplementation. The percentage of carcasses grading USDA Choice decreased (linear, P<.05; quadratic, P<.1) when choline was added at 60 g/day. Hot carcass weight, marbling, dressing percent, and 12th rib fat thickness were not affected significantly by either fat or choline. Ruminally protected choline can improve average daily gain and feed efficiency of finishing cattle.

Betaine As A Dietary Supplement For Finishing Cattle, C.A. Loest, R.D. Hunter, R.H. Wessels, James S. Drouillard, Evan C. Titgemeyer Jan 1998

Betaine As A Dietary Supplement For Finishing Cattle, C.A. Loest, R.D. Hunter, R.H. Wessels, James S. Drouillard, Evan C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

One hundred seventy five steers (902 lb initial body weight) were used in a finishing study to determine the effect of betaine, provided either as feed-grade betaine (Betafin-S6, Finnsugar Bioproducts) or as concentrated separator by-product (CSB; desugared beet molasses), on animal performance and carcass characteristics. Steers were fed a finishing diet based on steam-flaked and dry-rolled corn. Treatments included 10.5 or 21 g/steer daily supplemental feed-grade betaine or 250 g (15.5 betaine) or 500 g (31 g betaine) of CSB per steer daily. Dry matter intakes increased (linear, P<0.1) for steers supplemented with feed- grade betaine. Average daily gains and feed efficiencies were not affected by treatments. Dressing percent and twelfth rib back fat increased (P<0.1) for steers that received feed-grade betaine. Rib-eye area decreased (P<0.1) when steers were supplemented with either feed-grade betaine or CSB. Yield grades were significantly higher (linear, P<0.1) for cattle receiving supplemental CSB or feed-grade betaine (quadratic, P<.05). Hot carcass weights, KPH, marbling scores, and percentage of carcasses grading USDA Choice were not affected by supplemental betaine. In this study, betaine supplementation did not markedly alter growth performance, but carcass fatness tended to increase for both supplements.

Influence Of Melengesterol Acetate (Mga®) And Implus-H® Implants On Rate Of Gain, Feed Efficiency, And Carcass Characteristics Of Culled Beef Cows Fed A High Concentrate Ration, M.F. Spire, J.C. Galland, John A. Unruh, James S. Drouillard Jan 1998

Influence Of Melengesterol Acetate (Mga®) And Implus-H® Implants On Rate Of Gain, Feed Efficiency, And Carcass Characteristics Of Culled Beef Cows Fed A High Concentrate Ration, M.F. Spire, J.C. Galland, John A. Unruh, James S. Drouillard

Kansas Agricultural Experiment Station Research Reports

No statistical differences were detected in feedlot performance or carcass traits between control culled beef cows and those that were treated with melengesterol acetate (MGA®) and/or Implus-H® when fed in a feedyard for 56 days before slaughter. All groups performed well, indicating that this practice may be used to improve the market value of culled cows. Cow health during the feeding period is a major concern.

Differences In Efficiency Among Kansas Beef Cow Producers, S. Eidson, Michael R. Langemeier, R. Jones Jan 1998

Differences In Efficiency Among Kansas Beef Cow Producers, S. Eidson, Michael R. Langemeier, R. Jones

Kansas Agricultural Experiment Station Research Reports

Beef cow producers must manage costs of production and improve production efficiency to compete with hog and poultry and other beef cattle producers. A sample of 46 beef cow enterprises from the Kansas Farm Management database was used to measure technical, economic, and overall efficiencies. On average the farms were 92% technically efficient, 80% economically efficient and 73% overall efficient. Our results suggest that 5% increases in economic and scale efficiencies would increase profit per cow by $20 and $24, respectively.

Comparison Of Implants In Grazing Heifers And Carryover Effects On Finishing Gains And Carcass Traits, F.K. Brazle Jan 1998

Comparison Of Implants In Grazing Heifers And Carryover Effects On Finishing Gains And Carcass Traits, F.K. Brazle

Kansas Agricultural Experiment Station Research Reports

Crossbred yearling heifers were allotted randomly to three grazing implant treatments: 1) control (CONT), 2) Component® E-H (CEH), and 3) Ralgro® (RAL). After grazing native grass for 74 days, the heifers were transported to a western Kansas feedlot. All heifers were implanted with Synovex-H® upon arrival at the feedlot and were reimplanted70 days later with Finaplix-H®. The CEH heifers gained faster while on grass (P<.10) and in the feedlot than the RAL heifers. The CEH heifers had heavier carcasses than RAL heifers. Control heifers had the largest ribeyes. Other carcass traits, including USDA quality grade, were not influenced by pasture treatment. In this study, administration of CEH to heifers grazing native grass optimized overall performance whencombined with the feedlot implants (Synovex-H and Finaplix-H).

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

Kansas Agricultural Experiment Station Research Reports

In nursery pigs, the greatest digestibilities of DM, N, and OE were observed with soft sorghum. In finishing pigs, no difference was observed in digestibility of nutrients among the sorghum genotypes. Chicks fed soft sorghum had better F/G than chicks fed medium and hard sorghum. Finally, thermal processing (steam flaking and extrusion) improved ADG and F/G and digestibilities of DM, N, and GE compared to grinding (coarse and fine).; Swine Day, Manhattan, KS, November 19, 1998

Effects Of Enzyme Supplementation And Particle Size Of Wheat-Based Diets On Nursery And Finishing Pigs (1998), I Mavromichalis, G A. Kennedy, Robert H. Hines, B W. Senne, S P. Sorrell, Joe D. Hancock, Joel M. Derouchey Jan 1998

Effects Of Enzyme Supplementation And Particle Size Of Wheat-Based Diets On Nursery And Finishing Pigs (1998), I Mavromichalis, G A. Kennedy, Robert H. Hines, B W. Senne, S P. Sorrell, Joe D. Hancock, Joel M. Derouchey

Kansas Agricultural Experiment Station Research Reports

In nursery pigs, enzyme supplementation generally had no effect on ADG or F/G, but a trend occurred for greater digestibility of DM in pigs fed enzymes. However, one notable interaction occurred. Enzyme supplementation gave improved F/G at the coarser (l,300 mm) particle size but not at the finer (600 or 400 mm) particle sizes. In finishing pigs, trends for better F/G and digestibilities of DM and N with enzyme supplementation occurred in one experiment (1,300 vs 600 mm) but not in the other experiment (600 vs 400). Thus, the effects of enzyme supplementation were neither large nor consistent, but wheat …

Effects Of Inorganic And Organic Acids On Urine Ph In Lactating Sows (1998), Robert H. Hines, H Coa, D J. Lee, C A. Maloney, J S. Park, Joel M. Derouchey, Joe D. Hancock Jan 1998

Effects Of Inorganic And Organic Acids On Urine Ph In Lactating Sows (1998), Robert H. Hines, H Coa, D J. Lee, C A. Maloney, J S. Park, Joel M. Derouchey, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

Some swine practitioners are advocating the use of dietary acidifiers to reduce urine pH and, thereby, reduce the incidence of urinary tract infections. In our experiment, sows fed an inorganic (phosphoric) acid had lower urine pH than sows fed diets with organic (fumaric, lactic, formic, propionic, and citric) acids. Indeed, the organic acids at 1.5% and 3.0% of the diet increased blood pH and decreased pC02,indicating that these sows were in a more alkalotic (not acidotic) state.; Swine Day, Manhattan, KS, November 19, 1998

Influence Of Spirulina Platensis On Growth Performance Of Weanling Pigs (1998), G S. Grinstead, J Sawyer, K Maxwell, R Stott, A Moser, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen Jan 1998

Influence Of Spirulina Platensis On Growth Performance Of Weanling Pigs (1998), G S. Grinstead, J Sawyer, K Maxwell, R Stott, A Moser, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

We conducted three experiments to evaluate the influence of an algal feed additive, Spirulina platensis, on weanling pig performance. Two experiments conducted under commercial production conditions indicated a response to Spirulina platensis in meal-based diets but not pelleted diets. Another experiment concluded that Spirulina platensis tended to improve F/G early in the trial but not for cumulative performance. Results of these three experiments suggest that Spirulina platensis added at low inclusions to the diet may enhance performance. However, the results lacked consistency across experiments and warrant further investigation.; Swine Day, Manhattan, KS, November 19, 1998

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 Jan 1998

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

Seventy two early-weaned pigs (initially 12.4 lb) were used in a 14-d growth trial to evaluate a control diet (no added spray-dried egg albumin or animal plasma) or the control diet with 5% spray-dried plasma, 7% spraydried egg albumin~ or 2.5% spray-dried plasma plus 3.5% spray-dried egg albumin. Pigs fed 5% spray-dried animal plasma had greater ADG and improved F/G compared with those fed 7% spray-dried egg albumin, whereas pigs fed the control or a blend of spray-dried egg albumin plus spray-dried animal plasma had intermediate performance. These results suggest that the spray-dried egg albumin used is not an effective …

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

Kansas Agricultural Experiment Station Research Reports

Three hundred ninety high-lean growth pigs were used in a 17 d growth assay from 25 to 45 lb. Treatments consisted of soybean meal (SBM) from either high-oleic or check-line soybean varieties processed under pilot-plant processing conditions at four temperature ranges (80-85, 85-90, 90-95, 100-105 °C). Positive and negative controls were made using commercially obtained SBM (46.50%CP). Total dietary lysine was maintained at .95% except for the positive control (1.30%). Pigs fed commercial SBM with 1.30% dietary lysine had increased ADG and better F/G than pigs fed any other treatment. A SBM variety x processing temperature interaction was observed for …

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

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
