Comparison Of Anthelmintics For Pigs Raised In Outside Lots (1979), G L. Allee, D Schoneweis Jan 1979

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 …

Prevention And Control Of Enteric Swine Diseases (1979), R M. Phillips, N V. Anderson Jan 1979

Prevention And Control Of Enteric Swine Diseases (1979), R M. Phillips, N V. Anderson

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 Jan 1979

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 …

Allyl Trenbolone To Control Estrus In Gilts-Conception Rate And Litter Size After Treatment (1979), Duane L. Davis, J M. Robl, Jim L. Nelssen Jan 1979

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, …

Allyl Trenbolone To Control Estrus In Gilts-Effect Of Dose (1979), Duane L. Davis, J M. Robl, Jim L. Nelssen Jan 1979

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

Evaluation Of Various Antibiotics On Growth Rate And Feed Efficiency By Finishing Pigs (1979), G L. Allee Jan 1979

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, …

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 Jan 1979

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 …

Phosphorus Availability In Dry And High-Moisture Sorghum Grain For Growing Swine And Chicks (1979), M Trotter, G Allee Jan 1979

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 Fiber Source On Performance Of Weanling Pigs (1979), A J. Thulin, Robert H. Hines Jan 1979

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

Rumen Bacterial Endotoxins And Their Possible Role In The Sudden-Death Syndrome, Tiruvoor G. Nagaraja, E. Bartley, L. Fina, H. Anthony, H. Leipold Jan 1979

Rumen Bacterial Endotoxins And Their Possible Role In The Sudden-Death Syndrome, Tiruvoor G. Nagaraja, E. Bartley, L. Fina, H. Anthony, H. Leipold

Kansas Agricultural Experiment Station Research Reports

We have found that rumen bacteria contain endotoxins that are released into rumen fluid. Also rumen fluid from grain-fed cattle contains considerably more free endotoxin than rumen fluid from hay-fed cattle. Injecting cattle with rumen bacterial endotoxins may be involved with such diseases associated with high-grain feeding as the sudden death syndrome.

Effects From Using Ralgro Sequentially On Sexual Development Of Bulls And On Growth And Carcass Characteristics Of Steers And Bulls, L. Fink, L. Corah, G. Kiracofe, M. Mckee

Kansas Agricultural Experiment Station Research Reports

Forty-nine Simmental X Hereford and Hereford calves (24 bulls and 25 steers) were used to study the effect of Ralgro on growth, carcass traits, sex drive, sperm production, and development of sex organs. Approximately half of the bulls and half of the steers received a total of four 36-mg. Ralgro implants, one implant each 100 days (approximately 28, 128, 228 and 328 days of age). Implanted bulls and steers had higher average daily gains; however, the effect was greater in steers than bulls. Ralgro impaired all facets of sexual development measured. None of the implanted bulls could have been used …

Pelvic Area, Calving Ease And Rebreeding In First Calf Heifers, R.R. Schalles, A.T. Fleck, L.R. Corah, G. Kiracofe Jan 1979

Pelvic Area, Calving Ease And Rebreeding In First Calf Heifers, R.R. Schalles, A.T. Fleck, L.R. Corah, G. Kiracofe

Kansas Agricultural Experiment Station Research Reports

Pelvic area had little influence on the number or severity of calving problems after size and condition of two-year-old first-calf heifers, sex and weight of their calf, and genetic background of the heifer and her calf were accounted for. Little difference in rebreeding was attributed to calving difficulty, although heifers that had Caesarean deliveries rebred about two weeks later than those giving natural birth.

Delayed Winter Supplemental Feeding And Year-Round Mineral Supplementation Of Beef Cows On Native Range, J. Pruitt, R.R. Schalles, L.H. Harbers, Clenton E. Owensby, E.F. Smith Jan 1979

Delayed Winter Supplemental Feeding And Year-Round Mineral Supplementation Of Beef Cows On Native Range, J. Pruitt, R.R. Schalles, L.H. Harbers, Clenton E. Owensby, E.F. Smith

Kansas Agricultural Experiment Station Research Reports

Polled Hereford cows on native Flint Hills pasture not supplemented until February lost more weight from December to February, lost less from February to May, and were in poorer condition before calving than cows supplemented beginning in November. But calf survival, birth weight, and calf average daily gain were similar for both groups. Feeding cows a calcium, phosphorus, trace mineral mix did not improve any measure of cow or calf performance.

Effects Of Ralgro And Des Implants During The Suckling Period On Later Reproductive Performance Of Beef Heifers, L.R. Sprott, L.R. Corah, G.H. Kiracofe, M. Mckee, F.L. Schwartz Jan 1979

Effects Of Ralgro And Des Implants During The Suckling Period On Later Reproductive Performance Of Beef Heifers, L.R. Sprott, L.R. Corah, G.H. Kiracofe, M. Mckee, F.L. Schwartz

Kansas Agricultural Experiment Station Research Reports

Heifers were given either one or two Ralgro implants or one DES implants during the suckling period with no obvious effect on later reproductive performance when the heifers were bred as yearlings. However, conception rates in control heifers were low in two trials, so more studies are needed for conclusive results.

Evaluating The Breeding Potential Of Yearling Bulls, L. Corah, G. Kiracofe, M. Mckee, R.R. Schalles Jan 1979

Evaluating The Breeding Potential Of Yearling Bulls, L. Corah, G. Kiracofe, M. Mckee, R.R. Schalles

Kansas Agricultural Experiment Station Research Reports

Two years of research with nine herds indicated one of two yearling bulls with a herd usually will sire most of the calves. In six of the nine cases, the bull we pre-evaluated as most sexually active was the sire of the most of the calves. So a brief pre-breeding libido evaluation may help estimate breeding potential. In data from one herd the bull dominant as a yearling continued to be dominant as a two-year-old. Our data also indicated active breeding yearling bulls easily breed more than 20 to 25 cows during their first breeding season.

Yield And Quality Of Six Summer Annual Forages, M. Nuwanyakpa, Gerry L. Posler, K.K. Bolsen, H. Ilg Jan 1979

Yield And Quality Of Six Summer Annual Forages, M. Nuwanyakpa, Gerry L. Posler, K.K. Bolsen, H. Ilg

Kansas Agricultural Experiment Station Research Reports

In 1977, all summer annual forages studied produced excellent yields. Based on leafiness and regrowth ability, sudangrasses and pearl millet appeared to be best for early vegetative and boot cutting management. The sorghum-sudan hybrids had suitable yields and quality at all harvest stages. The hybrid forage sorghum appeared best suited for soft-dough-stage harvest although yields of pearl millet and sorghum-Sudan hybrids were also excellent.
