Allyl Trenbolone To Control Estrus In Gilts-Conception Rate And Litter Size After Treatment (1979), Duane L. Davis, J M. Robl, Jim L. Nelssen
Allyl Trenbolone To Control Estrus In Gilts-Conception Rate And Litter Size After Treatment (1979), Duane L. Davis, J M. Robl, Jim L. Nelssen
Kansas Agricultural Experiment Station Research Reports
Control of estrus in gilts is theoretically possible by feeding a progestogen for 18 consecutive days. During the feeding period the progestogen suppresses estrus in all gilts and when withdrawn from the feed, all animals are expected to come in heat 4 to 7 days later. To be useful, the synchronizing agent must meet two criteria: (1) it must effectively control the time of estrus, and (2) it must not adversely affect fertility. We conducted this trial to evaluate a progestogen, allyl trenbolone, with respect to these criteria. Allyl trenbolone is not presently available to swine producers.; Swine Day, Manhattan, …
Effects Of Various Water Medications On Performance And Feed And Water Consumption By Pigs Weaned At 3 Or 4 Weeks Of Age (1979), G L. Allee, D Schoneweis
Effects Of Various Water Medications On Performance And Feed And Water Consumption By Pigs Weaned At 3 Or 4 Weeks Of Age (1979), G L. Allee, D Schoneweis
Kansas Agricultural Experiment Station Research Reports
Two trials using 216 pigs were conducted to evaluate effects various water medications have on performance and feed and water consumption by pigs weaned at 3 and 4 weeks of age. Water medication had no effect on pig performance. Pigs weaned at 3 weeks of age consumed an average of 0.8 quart of water per day for the first five days after weaning, compared with an average of 1.1 quarts per day by those weaned at 4 weeks of age. Adding syrup (500 ml/5 gallon) doubled the water consumption of both groups. Water medications did not reduce water consumption.; Swine …

Evaporative Cooling Systems For Swine (1979), David A. Nichols, D R. Ames, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Two trials involving 168 finishing pigs were conducted to compare continuous fogging with intermittent wetting to reduce heat stress in swine. In the second trial, intermittent wetting by sprinklers (1 min. sprinkle, 29 min. dry) significantly improved (P<.05) average daily gain and average daily feed over control, yet no significant differences in feed to gain ratios were observed between controls and fogged pigs in the second trial.; Swine Day, Manhattan, KS, November 8, 1979
Comparison Of Anthelmintics For Pigs Raised In Outside Lots (1979), G L. Allee, D Schoneweis
Comparison Of Anthelmintics For Pigs Raised In Outside Lots (1979), G L. Allee, D Schoneweis
Kansas Agricultural Experiment Station Research Reports
One hundred fifty crossbred pigs averaging 21 lbs. initially were used to evaluate the effects of Banminth or Tramisol on performance of pigs housed in worm-contaminated dirt lots. Neither anthelmintic significantly affected average daily gain or feed efficiency. Pigs fed Banminth continuously were 5% more efficient in feed utilization during the starter phase and 4% more efficient in feed utilization during the grower phase than nonwormed pigs. Pigs fed Banminth had no liver scarring and no ascarids in gastrointestinal tracts at 125 pounds. Untreated pigs and those treated with Tramisol had lever scarring and ascarids in the gastrointestinal tracts at …

Effects Of Steam Pelleting And Extruding Sorghum Grain-Soybean Meal Diets On Phosphorus Availability For Swine (1979), M Trotter, G Allee
Kansas Agricultural Experiment Station Research Reports
Two feeding trials and three phosphorus balance studies were conducted to compare the effect of steam pelleting, extruding, and grinding on phosphorus availability. The results indicate that steam pelleting or extruding has little, if any, effect on the availability of phosphorus for finishing swine (100 to 220 lbs.).; Swine Day, Manhattan, KS, November 8, 1979
Artificial Rearing Of Baby Pigs With Twice-A-Day Feeding And Cow Colostrum (1979), M T. Noll, G L. Allee
Artificial Rearing Of Baby Pigs With Twice-A-Day Feeding And Cow Colostrum (1979), M T. Noll, G L. Allee
Kansas Agricultural Experiment Station Research Reports
Four experiments involving 140 pigs were conducted to evaluate cow colostrum and twice-a-day feeding in artificial rearing of baby pigs. Piglets were allowed to nurse the sow for 15 hours after birth and allotted by litter and weight to milk replacer or milk replacer plus cow colostrum. Piglets were housed in individual wire cages and fed four times on day one, three times on day two, and twice daily days 3 through 21. Dry feed was offered to pigs after day 14. Pigs were removed from the individual cages and moved to a conventional nursery at 21 days of age. …
Evaluation Of Comingling Pigs Before Weaning To Reduce Weaning Stress (1979), A J. Thulin, Robert H. Hines
Evaluation Of Comingling Pigs Before Weaning To Reduce Weaning Stress (1979), A J. Thulin, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Two trials were conducted to evaluate the management practice of comingling litters one week before weaning to help reduce weaning stress. Pigs which were comingled before weaning gained slightly faster the first two weeks after weaning than pigs mixed at weaning, but overall pig performance to 7 to 8 weeks of age was similar for rate of gain and feed efficiency.; Swine Day, Manhattan, KS, November 8, 1979

Kansas Agricultural Experiment Station Research Reports
Work on colibacillosis has been concentrated on isolating and identifying enterotoxigenic E. coli from specimens submitted to the Veterinary Diagnostic Laboratory. Strains of enterotoxigenic E. coli isolated in the laboratory were sent to veterinary practitioners to use in producing of autogenous vaccines for producers to prevent neonatal diarrhea. Of 1,179 E. coli isolated from clinical specimens and tested for enterotoxin production, more than 22 percent of these isolates were disease-producing enterotoxigenic strains. These enterotoxigenic E. coli were sent to 136 veterinary practitioners for use in autogenous vaccines. The diagnostic laboratory also serves as a center for storing these vaccine strains.; …
Evaluation Of Hover Types With And Without Supplemental Heat For Finishing Pig Performance (1979), G L. Allee, David A. Nichols, Robert H. Hines
Evaluation Of Hover Types With And Without Supplemental Heat For Finishing Pig Performance (1979), G L. Allee, David A. Nichols, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
One hundred sixty Yorkshire barrows and gilts were used to evaluate supplemental heat and various types of hovers for finishing pigs during December, 1978, and January, 1979. Hovers constructed of plywood, straw, and plywood covered with foil were placed over pens with and without catalytic heaters to determine the effect of each on performance. Hovers modified the pig's environment by an average of 80 straw hover, 90 foil covered plywood, and 30 plywood hover. Average daily gain and feed required per pound of gain were similar for all treatments. Pigs fed in pens with catalytic heaters gained slightly faster and …
Evaluation Of Various Antibiotics On Growth Rate And Feed Efficiency By Finishing Pigs (1979), G L. Allee
Evaluation Of Various Antibiotics On Growth Rate And Feed Efficiency By Finishing Pigs (1979), G L. Allee
Kansas Agricultural Experiment Station Research Reports
Two trials involving 300 finishing pigs (120-220 lbs.) were conducted to evaluate Tylan, Stafac, Lincomix, and Flavomycin by growth rate and feed efficiency. In trial I, none of the antibiotics improved growth rate or feed efficiency. In trial II, where pigs were more crowded, feeding an antibiotic slightly, but not significantly, increased daily gain (0 to 8% improvement) and feed efficiency (3 to 9%), with no significant difference among antibiotics. These studies demonstrate that the response or lack of response to feeding low levels of antibiotics during the finishing phase will depend on the level of stress imposed.; Swine Day, …

Kansas Agricultural Experiment Station Research Reports
A major threat to swine enterprises is the possible introduction of disease when new breeding animals are purchased and introduced. So, methods of introducing new genetic material while minimizing the potential for introducing disease are needed. Transfer of embryos from a donor sow in another herd or country would minimize disease risks. Already used to introduce new breeding stock into Specific Pathogen Free herds and other closed herds, embryos now are placed in the recipient gilt's or sow1s uterus within a few hours after their recovery from the donor. That method prevents export and limits application of swine embryo transfer …
Allyl Trenbolone To Control Estrus In Gilts-Effect Of Dose (1979), Duane L. Davis, J M. Robl, Jim L. Nelssen
Allyl Trenbolone To Control Estrus In Gilts-Effect Of Dose (1979), Duane L. Davis, J M. Robl, Jim L. Nelssen
Kansas Agricultural Experiment Station Research Reports
Replacement gilts frequently do not fit smoothly into existing breeding and farrowing schedules because time of estrus cannot be predicted. Being able to program replacement gilts into a breeding herd would improve management, so we investigated the effectiveness of a synthetic progestogen, allyl trenbolone , to control estrus in gilts. Allyl trenbolone is not presently available to swine producers.; Swine Day, Manhattan, KS, November 8, 1979
Phosphorus Availability In Dry And High-Moisture Sorghum Grain For Growing Swine And Chicks (1979), M Trotter, G Allee
Phosphorus Availability In Dry And High-Moisture Sorghum Grain For Growing Swine And Chicks (1979), M Trotter, G Allee
Kansas Agricultural Experiment Station Research Reports
We used 117 crossbred pigs and 260 male White Leghorn chicks to determine the availability of phosphorus in high-moisture sorghum grain treated with propionic acid or stored in an oxygen limiting structure, and in field-dried sorghum grain. Bone breaking force as the criterion in the pig studies and tibia bone ash as the criterion in the chick studies gave availability estimates of 19, 42, and 43% for the pig and 25, 46, and 48% for the chick for dry, HMPA and HMO2L, respectively.; Swine Day, Manhattan, KS, November 8, 1979
Effect Of High-Moisture Grain On Availability Of Phosphorus For Swine (1979), M Trotter, G Allee
Effect Of High-Moisture Grain On Availability Of Phosphorus For Swine (1979), M Trotter, G Allee
Kansas Agricultural Experiment Station Research Reports
A feeding trial and two phosphorus balance studies were conducted to compare the availabilities of phosphorus from high-moisture sorghum grain treated with propionic acid (1.2% acid, 23% moisture), grain stored in an oxygen limiting structure (27% moisture), and field-dried sorghum grain (13% moisture). Bone and phosphorus retention data indicated that the phosphorus in high-moisture sorghum grain is more available than phosphorus in field-dried sorghum grain.; Swine Day, Manhattan, KS, November 8, 1979
Effect Of Fiber Source On Performance Of Weanling Pigs (1979), A J. Thulin, Robert H. Hines
Effect Of Fiber Source On Performance Of Weanling Pigs (1979), A J. Thulin, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Ninety-six Yorkshire pigs, weaned at 5 to 6 weeks of age and averaging 9.5 kg (20.9 lbs.) were used to determine the effects of diets with increased fiber from oats, beet pulp, wheat bran, alfalfa meal or wheat shorts on performance and fecal consistency. Pigs fed the control, 20% oats, 10% beet pulp or 21.2% wheat bran diets had the best average daily gain; those fed the 48.5% wheat shorts, the poorest daily gain. Average daily feed intake was similar except that pigs fed the 20% oats diet consumed more feed (P<.05) than those fed the 48.5% wheat shorts. Feed efficiency was similar for all diets. Pigs fed the control, 20% oats, 10% beet pulp or 21.2% wheat bran diets had better average daily diarrhea scores than those fed the 7.6% alfalfa meal or 48.5% wheat shorts diets.; Swine Day, Manhattan, KS, November 8, 1979
