A Rapid Method Of Analysis Of Corn Grain For Dairy Cattle, G. Garcia, R. Malvetti, L.H. Harbers Jan 1989

A Rapid Method Of Analysis Of Corn Grain For Dairy Cattle, G. Garcia, R. Malvetti, L.H. Harbers

Kansas Agricultural Experiment Station Research Reports

Calibration equations for near infrared reflectance spectroscopy (NIRS) have been either purchased from the manufacturer or developed in the laboratory. Comparative analysis with standard laboratory procedures indicate that NIRS may be used for analyzing dairy feedstuffs, when proper calibration is made with local feedstuffs. NIRS is a new, rapid method of analyzing feedstuffs that reduces the time from several days to one minute or more after grinding and subsampling. The instrument needs to be calibrated from nutrient analyses made in the laboratory. Many calibrations may be purchased from the manufacturer of the instrument; however, we have found that many Kansas ...


Comparison Of Growth Of Holstein Heifers Fed 100% Or 115% Of Nrc Requirements, M. G. Daccarett, J.L. Morrill Jan 1989

Comparison Of Growth Of Holstein Heifers Fed 100% Or 115% Of Nrc Requirements, M. G. Daccarett, J.L. Morrill

Kansas Agricultural Experiment Station Research Reports

One hundred and one Holstein heifers from the KSU Dairy Unit were used in this experiment. They were assigned to two treatments in which they were fed either 100% or 115% of the 1988 NRC requirements of energy, protein, major minerals, and major vitamins. Body measurements (height, length, heart girth, weight, body condition scores, and backfat thickness) were recorded. Rations for each group were formulated using the average wt of the heifers. Results suggest that feeding 115% of NRC requirements produces larger frame heifers (without excess body condition), with potential for earlier calving, compared to feeding 100% of NRC requirements ...


Evaluation Of Water Oxygenation On Milk Production: Milk Composition And Somatic Cell Concentration In Milk, John E. Shirley, C. Galdamez, J. Estrada Jan 1989

Evaluation Of Water Oxygenation On Milk Production: Milk Composition And Somatic Cell Concentration In Milk, John E. Shirley, C. Galdamez, J. Estrada

Kansas Agricultural Experiment Station Research Reports

Forty Holstein cows in mid-lactation were utilized to evaluate the effects of water oxygenation on milk production, milk composition, and somatic cell count. Cows were fed a total mixed ration consisting of 25% alfalfa, 25% corn silage, and 50% corn-soy concentrate on a dry matter basis. Treatments included a 7-day preliminary period followed by two 28-day periods in which the treatments were reversed. Water consumption, milk production, milk composition, and somatic cell count were not different between treatments. Cows receiving oxygenated water were more docile and easily managed than control cows. Ozone introduced into water forms hydrogen peroxide, nitrous oxide ...


Pregnancy Rates Of Dairy Cows At First Service: Influence Of Gonadotropin-Releasing Hormone And Timing Of Ai Relative To Estrus, Jeffrey S. Stevenson, M.O. Mee, R.K. Scoby, Y. Folman Jan 1989

Pregnancy Rates Of Dairy Cows At First Service: Influence Of Gonadotropin-Releasing Hormone And Timing Of Ai Relative To Estrus, Jeffrey S. Stevenson, M.O. Mee, R.K. Scoby, Y. Folman

Kansas Agricultural Experiment Station Research Reports

We demonstrated that gonadotropin-releasing hormone (GnRH or Cystorelin®) failed to improve pregnancy rates at the first service. When GnRH injection and insemination are both carried out either in early or late estrus or if cows are bred in early estrus and given a GnRH injection later in estrus, pregnancy rates are reduced by 9 to 13 percentage points compared to breeding according to the am-pm rule without GnRH treatment (control). Pregnancy rates of cows injected with GnRH early in estrus and bred in late estrus were similar to controls injected with saline and inseminated late in estrus (46 vs 43 ...


The Use Of Bovine Somatotropin (Bst) In Dairy Cattle, J. Estrada, John E. Shirley Jan 1989

The Use Of Bovine Somatotropin (Bst) In Dairy Cattle, J. Estrada, John E. Shirley

Kansas Agricultural Experiment Station Research Reports

We all have heard about the use of BST in lactating dairy cattle during the last 6 to 8 years, but what is BST? Bovine somatotropin is another dairy management tool developed to improve the efficiency and reduce the cost of producing milk. It is the newest in a list of technological advances in the dairy industry, such as genetic improvements, nutrition, health, housing, milking equipment and techniques, embryo transfer, and DHI records. BST is a natural protein produced in the anterior pituitary gland of all cattle. Like other proteins, BST is composed of various amino acids (190-199). BST is ...


Involution Of The Uterus Of Dairy Cattle, Edward P. Call Jan 1989

Involution Of The Uterus Of Dairy Cattle, Edward P. Call

Kansas Agricultural Experiment Station Research Reports

The rate of involution of the bovine uterus is remarkable. By 20 days after calving, tissue sloughing and hemorrhaging have ceased, and the size of the uterus has been reduced by more than 80%. By 40 days, the uterus has completely involuted except for isolated pockets of leukocytes. Any reproductive or metabolic disorders around calving will delay involution. A preventive herd health program (PHHP) including a reproductive examination of cows within a month after calving will pay dividends in improved reproductive performance. With a sound PHHP, servicing cows on the first heat after 42 days fresh is recommended.; Dairy Day ...


Polled Hereford And Simmental Milk Production, R.R. Schalles, S. Kimbrough, K.O. Zoellner, D.D. Simms Jan 1989

Polled Hereford And Simmental Milk Production, R.R. Schalles, S. Kimbrough, K.O. Zoellner, D.D. Simms

Kansas Agricultural Experiment Station Research Reports

The weigh-suckle-weigh method was used to measure milk consumption by 265 calves from 159 Polled Hereford and Simmental cows over 3 years. Calves nursing Polled Hereford cows consumed an average of 11.2 lbs of milk per day, with a peak of 15lbs at 50 days post"¢ calving. calves nursing Simmental cows consumed an average of 16.8 lbs of milk per day, with a peak of 20 lbs at 58 days after calving. All increase of 1lb in daily milk consumption produced approximately 20 lbs increase in weaning weight.


Feed Utilization During Late Gestation By Polled Hereford And Simmental Cows, R.R. Schalles, G.H. Kiracofe, J.W. Wright Jan 1989

Feed Utilization During Late Gestation By Polled Hereford And Simmental Cows, R.R. Schalles, G.H. Kiracofe, J.W. Wright

Kansas Agricultural Experiment Station Research Reports

Thirty-one Polled Hereford and 29 Simmental cows were individually fed two energy levels for about the last 4 months before calving. Weight, condition score, backfat thickness, and reproduction were evaluated. No differences were found in efficiency of feed utilization between breeds or between energy levels. These cows started the experiment in moderate body condition, and a 10% reduction in dietary energy level during late gestation did not affect their reproductive performance.


Splay-Foot In Cattle, R.R. Schalles, R.W. Markham, H.W. Leipold, M.F. Spire Jan 1989

Splay-Foot In Cattle, R.R. Schalles, R.W. Markham, H.W. Leipold, M.F. Spire

Kansas Agricultural Experiment Station Research Reports

Angular limb deformity, observed in several breeds of cattle, results in a knock-kneed and splay-footed condition in the front legs. This study shows that angular limb deformity is a congenital structural defect, inherited as a simple, autosomal, recessive trait.


Syncro-Mate B® Induces Estrus In Cows Without Ovaries, W.J. Mcguire, G.H. Kiracofe Jan 1989

Syncro-Mate B® Induces Estrus In Cows Without Ovaries, W.J. Mcguire, G.H. Kiracofe

Kansas Agricultural Experiment Station Research Reports

Syncro-Mate B® was capable of inducing estrous behavior in ovariectomized cows. Lengthening the norgestomet implant period from 9 to 18 days did not prevent estrus. The ability of Syncro-Mate B to induce estrous behavior in ovariectomized cows helps explain the variable conception rates obtained after using this product in intact cows.


Limit Versus Full Creep-Feeding Of A High Protein Supplement To Calves Grazing Late Summer Bluestem, R.C. Cochran, C.E. Binns, L.R. Corah, T. Delcurto, E.S. Vanzant Jan 1989

Limit Versus Full Creep-Feeding Of A High Protein Supplement To Calves Grazing Late Summer Bluestem, R.C. Cochran, C.E. Binns, L.R. Corah, T. Delcurto, E.S. Vanzant

Kansas Agricultural Experiment Station Research Reports

Limit creep-feeding a 36% protein supplement (avg. salt concentration = 7.9%) was compared with unlimited consumption of the same supplement without salt (full creep-feeding) and with no supplementation. Average daily gain of steer calves was increased (P≤.06) by.19 (limit creep-feeding) and .38 (full creep-feeding) lb per day compared with non-supplemented calves. Average daily gain of heifer calves was not increased by creep feeding. Efficiency with which creep was converted to extra gain was poor for both limit and full creep-feeding groups. Little difference was observed in postweaning average daily gains; however, the calves given ad libitum access to ...


Influence Of Limited-Creep Feeding On Pre- And Postweaning Performance Of Spring-Born Calves, C.E. Binns, F.K. Brazle, Gerry L. Kuhl, D.D. Simms, K.O. Zoellner, L.R. Corah Jan 1989

Influence Of Limited-Creep Feeding On Pre- And Postweaning Performance Of Spring-Born Calves, C.E. Binns, F.K. Brazle, Gerry L. Kuhl, D.D. Simms, K.O. Zoellner, L.R. Corah

Kansas Agricultural Experiment Station Research Reports

Limit-feeding a high protein creep (36% CP) and a high energy creep (16% CP) was compared with no supplementation in a 61-day preweaning trial. Salt was used to limit daily creep intake to 1.5 to 2.0 lb per head. Calves given the limited energy and protein creep feeds outgained (P<.01) the unsupplemented calves by 0.2 lb and 0.3 lb, respectively. Conversion of creep feed consumed to extra gain was 6.7 and 5.3 for the energy and protein creep-fed calves, respectively (salt included). Trucking shrink of the noncreep-fed calves on the day of weaning and shipping was 4.9 lb and 7.0 lb less (P<.05) than that of the energy and protein creep-fed calves, respectively. Postweaning daily gains of the energy creep-fed calves was higher than those of both the protein creep-fed calves (P=.09) and the noncreep-fed calves (P<.01) by 0.3 lb and 0.5 lb, respectively. The energy creep-fed calves consumed more (P<.05) daily dry matter than the protein creep-fed and unsupplemented calves. Little difference was observed in postweaning feed conversion among creep treatments.

Performance Of Stocker Steers Grazing Smooth Bromegrass At Two Stocking Rates And Dewormed With Morantel Tartrate, K.P. Coffey, Joseph L. Moyer, Lyle W. Lomas

Kansas Agricultural Experiment Station Research Reports

Early-intensive grazing of smooth bromegrass reduced animal gains but improved gain/acre. Morantel tartrate reduced fecal nematode egg counts but had no effect on animal performance at either stocking rate


Additive-Treated Corn And Forage Sorghum Silages For Growing Cattle, K.K. Bolsen, A. Laytimi, R.A. Hart, F. Niroomand, J. Hoover Jan 1989

Additive-Treated Corn And Forage Sorghum Silages For Growing Cattle, K.K. Bolsen, A. Laytimi, R.A. Hart, F. Niroomand, J. Hoover

Kansas Agricultural Experiment Station Research Reports

Whole-plant corn silages were treated with Ecosyl® or Foraform® in one trial and Biomate® or Biomate + Cold-flo® in the second trial. In both trials, the silages were well preserved, but all were highly unstable in air during the first 3 to 4 weeks of the feed-out period. Foraform-treated silage was 2 to 6 degrees F cooler than its control, but Cold-flo-treated silage was 2 to 8 degrees F warmer during the first 10 days post-filling. Laboratory silo results showed that both control silages fermented extremely fast; however, inoculated silages had slightly lower pH and higher lactic acid values through the ...


Effect Of Foraform® On Fermentation Of Alfalfa, Corn, And Forage Sorghum Silages, K.K. Bolsen, A. Laytimi, A.D. Drysdale Jan 1989

Effect Of Foraform® On Fermentation Of Alfalfa, Corn, And Forage Sorghum Silages, K.K. Bolsen, A. Laytimi, A.D. Drysdale

Kansas Agricultural Experiment Station Research Reports

Foraform® was evaluated in four trials using alfalfa, corn, and two forage sorghums harvested in 1987 and ensiled in PVC laboratory silos. There was a dramatic crop by Foraform interaction, with Foraform delaying and restricting the fermentations, as expected, in alfalfa and corn. In both forage sorghum hybrids, although the ensiling process was delayed about 24 hours by the Foraform treatment, end-product silages had lower pH values and equal or higher lactic acid levels than untreated silages. Foraform was effective at both 60 to 90 F temperatures in alfalfa, with treated silages having lower lactic and acetic acids, ethanol, and ...


Influence Of Plant Parts On In Vitro Dry Matter Disappearance Of Forage Sorghum Silages, J. White, K.K. Bolsen Jan 1989

Influence Of Plant Parts On In Vitro Dry Matter Disappearance Of Forage Sorghum Silages, J. White, K.K. Bolsen

Kansas Agricultural Experiment Station Research Reports

Five mid- to late- season forage sorghum hybrids were used to plot the changes in silage in vitro dry matter disappearance (IVDMD) when their proportions of grain, leaf, sheath, and stalk were altered. The average IVDMD of the parts were: grain 76.9%, leaf 57.7%, sheath 52.7%, and stalk 60.8 percent. The grain proportion had a large positive effect on silage IVDMD dynamics, whereas the sheath plant part had a negative effect.


Impact Of Cash Settlement On Feeder Cattle Hedging Risk, J.R. Mintert, Ted C. Schroeder Jan 1989

Impact Of Cash Settlement On Feeder Cattle Hedging Risk, J.R. Mintert, Ted C. Schroeder

Kansas Agricultural Experiment Station Research Reports

One of the principal motivations for the introduction of cash settlement in feeder cattle futures contracts was to reduce basis risk. This study examined expected changes in hedging risk attributable to the adoption of cash settlement. The estimates of cash settlement futures hedging risks were generally small than estimates of hedging risks using the physical-delivery futures. The reduction in hedging risk was greatest for feeder steers meeting futures contract weight specifications, but reductions were also common for other weight classes and for heifers.


Performance, Carcass, And Meat Palatability Traits Of Open And 30-Month Old Heifers That Produced One Calf, A.W. Waggoner, J.R. Brethour, Michael E. Dikeman Jan 1989

Performance, Carcass, And Meat Palatability Traits Of Open And 30-Month Old Heifers That Produced One Calf, A.W. Waggoner, J.R. Brethour, Michael E. Dikeman

Kansas Agricultural Experiment Station Research Reports

Eighty-seven 3/8 Simmental x 5/8 Hereford heifers calved at 2 years of age and were designated as Single-Calf-Heifers (SCH). Twenty-six heifer mates that did not calve were designated as 2-year-old open heifers (2-OH), and 22, 1 year-old open heifers (1-OH) from the same source served as controls. All heifer groups were fed a high-grain diet for 112 to 137 days before slaughter. The SCH were started on feed about 1 month after calving, and their calves were weaned early about 5 weeks prior to slaughter. Thirty-three of the SCH were implanted with Synovex-H® after calving. Carcass data were ...


Effects Of Finapux® In Combination With Ralgro® And Synovex® On Performance And Carcass Characteristics Of Steers And Heifers, Gerry L. Kuhl, D. Simms, R. Ritter, P. Houghton, Paul D. Hartman Jan 1989

Effects Of Finapux® In Combination With Ralgro® And Synovex® On Performance And Carcass Characteristics Of Steers And Heifers, Gerry L. Kuhl, D. Simms, R. Ritter, P. Houghton, Paul D. Hartman

Kansas Agricultural Experiment Station Research Reports

Five field trials were conducted with 762 steers and heifers to evaluate Finaplix® in combination with Ralgro® or Synovex® for growing and finishing programs. Effects on cattle performance and carcass characteristics were inconsistent across trials. However, in general, implanting cattle with Finaplix and either Ralgro or Synovex tended to result in increased gain, final weight, and carcass weight, with little effect on backfat, loin eye area or kidney, heart, and pelvic fat. Marbling score and the percentage of cattle grading choice tended to be reduced slightly, although this was not usually significant.

New Concepts In Breeding Barn Design, D G. Levis Jan 1989

New Concepts In Breeding Barn Design, D G. Levis

Kansas Agricultural Experiment Station Research Reports

Many existing swine breeding facilities have been designed to control the environment, provide continuous boar-sow contact for stimulating recently weaned sows to cycle, reduce the distance a weaned sow or boar has to be moved for mating, and reduce construction costs by not constructing breeding pens to be used only for mating. Pork producers operating these types of facilities have had problems with efficiency and accuracy of estrous detection, low percentage (70%) of sows bred twice, slick breeding floors, and excessive labor requirements. A breeding facility should be arranged so the work routines, such as estrous detection; moving, mating, and ...


The Reaction Of Slaughter Hog Cash And Futures Prices To Usda Hogs And Pigs Reports, Ted C. Schroeder, J R. Mintert, John M. Blair Jan 1989

The Reaction Of Slaughter Hog Cash And Futures Prices To Usda Hogs And Pigs Reports, Ted C. Schroeder, J R. Mintert, John M. Blair

Kansas Agricultural Experiment Station Research Reports

This study examined the reaction of slaughter hog cash and futures prices to USDA Hogs and Pigs reports. Over the 1972-87 period, the nearby live hog futures price had $1/cwt or larger absolute price changes on 48% of the trading days immediately after the Hogs and Pigs report release compared to 6% of the days of the release, suggesting that the reports arc providing important new information to the market. Average price moves in cash and futures markets following the report releases were positive, suggesting that price usually increased the day after the reports. Over the 1972-87 period, the ...


Relationships Between Ovulation Rate And Litter Size For Flushed And Nonflushed Gilts, M T. Rhodes, Duane L. Davis, Jeffrey S. Stevenson Jan 1989

Relationships Between Ovulation Rate And Litter Size For Flushed And Nonflushed Gilts, M T. Rhodes, Duane L. Davis, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

We examined the effects of flushing (3.4 lb additional ground milo for approximately 2 wk before insemination) and pubertal status (inseminated at puberty or postpuberty) on ovulation rate and litter traits in gilts. Hushing resulted in 1.1 more eggs released at ovulation and 1.3 more pigs/litter. The response in litter size occurred primarily among gilts inseminated at their pubertal estrus. Neither flushing nor pubertal status affected prenatal survival. Data for 58 gilts were used to evaluate the relationship between ovulation rate and litter size. Litter size increased linearly with increased ovulation rate to a maximum of ...


The Effects Of Excess Dietary Lysine Additions On Growth Performance And Carcass Characteristics Of Finishing Pigs, G R. Stoner, Robert D. Goodband, Robert H. Hines, Jim L. Nelssen, Donald H. Kropf Jan 1989

The Effects Of Excess Dietary Lysine Additions On Growth Performance And Carcass Characteristics Of Finishing Pigs, G R. Stoner, Robert D. Goodband, Robert H. Hines, Jim L. Nelssen, Donald H. Kropf

Kansas Agricultural Experiment Station Research Reports

Seventy-five barrows (initial wt 136 lb) were utilized to evaluate the effects of dietary lysine levels ranging from .6 to 1.4% on growth performance and carcass characteristics. Pigs were fed a pelleted corn-sesame meal diet containing .6% lysine (17.7% crude protein) or diets containing .8, 1.0, 1.2, or 1.4% lysine provided by L-Iysine HCl. All other amino acids, vitamins, and minerals were calculated to be at least double the pig's requirement (NRC, 1988), to ensure that no nutrient other than lysine would limit performance. When the pen mean weight reached approximately 235 lb, six ...


Nutritional Considerations For Improved Lean Value, Jim L. Nelssen Jan 1989

Nutritional Considerations For Improved Lean Value, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

The swine industry is in a transitional period as it gears up to produce the lean meat required by the consumer. In fact, pork processors arc increasing the production of lean products (boneless loins, 95% fat-free hams) because consumers are willing to pay premiums for low-fat products. New methods of measuring the amount of lean pork (fat-a-meter, etc.) are being developed rapidly, in order to allow the packer to offer price differentials for lean compared to fat pigs. Pork producers, in my opinion, will adjust production systems to meet consumer demands for lean pork when monetary differentials are offered by ...


Effect Of Heat Treatment On The Nutritional Value Of Low-Inhibitor Soybeans For Nursery Growing, And Finishing Pigs, A J. Lewis, M A. Giesemann, Jim L. Nelssen, Joe D. Hancock Jan 1989

Effect Of Heat Treatment On The Nutritional Value Of Low-Inhibitor Soybeans For Nursery Growing, And Finishing Pigs, A J. Lewis, M A. Giesemann, Jim L. Nelssen, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

Two hundred forty nursery pigs (12.8 lb initial wt) were used in a 28-d growth assay to determine the nutritional value of Williams 82 soybeans with (+K) and without (-K) gene expression for the Kunitz trypsin inhibitor. Treatments were soybean type (+K and -K) and heat treatment (none, half-roasting, and full-roasting time), in a factorial arrangement. The soybeans were heated in a Roast-a-Tron roaster, ground, and added to corn-dried whey diets formulated to be limiting in lysine (.88%). Pigs fed diets with -K soybeans gained 21% faster and were 13% more efficient than pigs fed diets with + K soybeans ...


Effect Of Fat Combinations On Starter Pig Performance And Nutrient Digestibility, D F. Li, D L. Harmon, G E. Fitzner, D B. Jones, Jim L. Nelssen, Robert D. Goodband Jan 1989

Effect Of Fat Combinations On Starter Pig Performance And Nutrient Digestibility, D F. Li, D L. Harmon, G E. Fitzner, D B. Jones, Jim L. Nelssen, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

A growth trial was conducted to evaluate the effects of addition of soybean oil, coconut oil, 50% soybean oil: 50% coconut oil, 75% soybean oil: 25% coconut oil, and 25% soybean oil: 75% coconut oil on starter pig performance and nutrient digestibility. Diets were supplemented with 10% fat for the first 2 wk of the study and 5% for the final 3 wk. Fecal samples were collected from pigs by rectal massage, and apparent digestibility of DM, N, total fat, and fatly acids were calculated using chromic oxide (.3%) as an indigestible marker. Results demonstrated that ADG and feed efficiency ...


Effect Of Microbial Inoculants On The Storage Characteristics And Nutritional Value Of High Moisture Corn For Finishing Pigs, K K. Bolsen, D B. Jones, Robert H. Hines, Joe D. Hancock Jan 1989

Effect Of Microbial Inoculants On The Storage Characteristics And Nutritional Value Of High Moisture Corn For Finishing Pigs, K K. Bolsen, D B. Jones, Robert H. Hines, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

High moisture corn (23% moisture) was harvested in September, 1988, and stored in concrete silos until March, 1989. As the corn was harvested, it was divided into four treatment silos: high moisture corn (HMC) and HMC treated with inoculants containing lactobacillus, serratia, or streptococcus organisms. As a positive control, some of the corn was allowed to "field dry" to 14% moisture before being harvested. Two hundred forty finishing pigs were fed the com treatments. Approximately mid-experiment, samples of the corn and mixed diets were collected and evaluated for aerobic stability. At the end of the experiment, chromic oxide was added ...


Effect Of Fish Meal Quality On The Growth Performance Of Weanling Pigs, G R. Stoner, Jim L. Nelssen, Robert D. Goodband Jan 1989

Effect Of Fish Meal Quality On The Growth Performance Of Weanling Pigs, G R. Stoner, Jim L. Nelssen, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

The objective of this experiment was to evaluate three fish meal sources added to diets for the early-weaned pig. Fish meal sources were analyzed for total volatile nitrogen (TVN), which is an indicator of protein degradation of the raw material. Regardless of TVN content, pigs fed diets containing fish meal had better average daily gain (ADG) and average daily feed intake (ADFI) than pigs fed a diet without added fish meal. However, TVN content and chemical digestibility estimates of fish meal were associated with growth performance of starter pigs. Feed intake increased as TVN content increased. Although ADG was not ...


Evaluation Of Oral Escherichia Coli Bacterin And Water Medication On Performance Of Weaned Pigs, D A. Schoneweis, R I. Nicholson, G E. Fitzner, Robert H. Hines Jan 1989

Evaluation Of Oral Escherichia Coli Bacterin And Water Medication On Performance Of Weaned Pigs, D A. Schoneweis, R I. Nicholson, G E. Fitzner, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Odd-numbered pigs in new-born litters were vaccinated on d 1 with an oral Escherichia coli bacterin and their performance after weaning was compared with that of nonvaccinated littermates (even numbered pigs). In addition, each group of pigs was allotted to four water medication treatments that were administered from d 2 to d 6 after weaning. No significant interaction between vaccine and water treatment was observed. Vaccinated and non-vaccinated pigs performed similarly throughout the trial for the traits of ADG, ADFI, and F/G, indicating no beneficial effect from vaccination. Water medication after weaning did not affect performance or incidence of ...
