Growing Vegetables And Flowering Plants In A Greenhouse Supplied With Swine-Building Exhaust Air (1981), J K. Greig, C K. Spillman, B A. Koch
Kansas Agricultural Experiment Station Research Reports
Exhaust air from a Kansas State University swine-finishing house provides C02 and possibly other gases that are being used by vegetable plants in a KSU green house. In addition, a rock-storage system reduces fuel requirements of the greenhouse. Tomatoes and cucumbers have been the major food crops studied, but transplant production of geraniums, marigolds, snapdragons, and calendula also has been studied. Poinsettias were grown as a fall crop in 1980.; Swine Day, Manhattan, KS, November 12, 1981
Intermittant Antibiotics Vs. Continuous Antibiotics For The Finishing Pig (1981), Robert H. Hines
Intermittant Antibiotics Vs. Continuous Antibiotics For The Finishing Pig (1981), Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
The use of low or high level antibiotics fed continuously or intermittantly (2 week rotation) to 310 finishing pigs was evaluated in two trials. No significant improvements were noted for rate of gain or feed per lb. of gain in pigs fed antibiotics either continuously or intermittantly, as compared with pigs fed no antibiotics. No difference in performance was observed in pigs fed antibiotics intermittantly or continuously. The rotation of two high level antibiotics in Trial II did not significantly improve the performance of pigs over that of pigs fed no antibiotics.; Swine Day, Manhattan, KS, November 12, 1981
Effect Of Space Allowance With And Without Antibiotic On Performance Of Weaned Pigs (1981), Robert H. Hines
Effect Of Space Allowance With And Without Antibiotic On Performance Of Weaned Pigs (1981), Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Two feeding trials were conducted to evaluate 1.5, 2.5, and 3.5 sq. ft. of space allowance for the four week old weaned pig. In addition, performance of pigs fed an antibiotic (ASP 250) versus no antibiotic at each space allowance was evaluated. The pigs fed an antibiotic gained significantly faster than pigs receiving no antibiotic; however, most of the improvements were observed the first three weeks of the five week trial. Maximum growth was observed at 2.5 sq. ft. and 3.5 sq. ft. of space allowance. Pigs given 1.5 sq. ft. gained slightly slower throughout the trial. This study suggests …
Effect Of Diet And Method Of Feeding On Performance Of Pigs Weaned At Three Weeks Of Age (1981), J R. Clarkson, G L. Allee
Effect Of Diet And Method Of Feeding On Performance Of Pigs Weaned At Three Weeks Of Age (1981), J R. Clarkson, G L. Allee
Kansas Agricultural Experiment Station Research Reports
Four trials involving 600 pigs weaned at 15 to 23 days were conducted to evaluate pig performance as affected by added whey and method of feeding during the first week after weaning. Pigs fed 20% dried whole whey gained faster the first two weeks after weaning and during the 35-day trial than did pigs fed a milo-soybean meal diet with no whey. Ten percent dried whole whey did not improve performance over that of the control diet, and 30% dried whey showed no advantage over the 20% whey diet. Pigs fed delactosed whey substituted on a protein basis for 20% …
Performance Of Weanling Pigs As Influenced By Feeding Insect-And Fungal-Damaged Grain Sorghum (1981), J C. Dietz, Keith C. Behnke, G A. Allee, C W. Deyoe
Performance Of Weanling Pigs As Influenced By Feeding Insect-And Fungal-Damaged Grain Sorghum (1981), J C. Dietz, Keith C. Behnke, G A. Allee, C W. Deyoe
Kansas Agricultural Experiment Station Research Reports
Using 128 crossbred pigs with an average initial weight of 18.3 Kg, we determined the effect that insect- and fungal-damaged sorghum would have on the pigs' performance. No differences were found in daily feed consumption for any treatment during a 28-day feeding trial. Average daily gains and feed efficiencies were similar to those of the control for pigs fed grain sorghum that had been damaged by lesser grain borer; red beetle; a mixture of lesser grain borer, flat grain beetle, and indian meal moth, or Aspergilas Candidus. Pigs fed grain sorghum damaged by rice weevil showed lower average daily gains …
Effect Of Diet Complexity And Physical Form On Performance Of Starter Pigs And On Efficiency Of Feed Processing (1981), S Pollmann, Keith C. Behnke, G Allee
Effect Of Diet Complexity And Physical Form On Performance Of Starter Pigs And On Efficiency Of Feed Processing (1981), S Pollmann, Keith C. Behnke, G Allee
Kansas Agricultural Experiment Station Research Reports
In two trials 330 crossbred pigs averaging 12 pounds were used to evaluate the effect of starter diet complexity and physical form on average daily gain, feed efficiency, and cost of gain. In a processing efficiency trial, pellet durability, amount fines returned, and power consumption were determined. A diet with milo-soybean meal as a basis (simple) was compared with one containing 3% tallow and 5% dried whey in milo-soybean meal (complex). Each was processed into three physical forms: meal, pellet, and crumble. Adding 3% tallow and 5% whey to milo-soybean meal diet did not improve performance of the starter pigs …
Soybean Protein In Milk Replacer Diets For Baby Pigs (1981), G L. Allee, P Hsu, R S. Prather
Soybean Protein In Milk Replacer Diets For Baby Pigs (1981), G L. Allee, P Hsu, R S. Prather
Kansas Agricultural Experiment Station Research Reports
Two trials, involving 108 pigs, were conducted to evaluate the effects of replacing milk protein with various levels of soybean protein in milk replacer diets. Pigs fed diets in which 25 or 50% of the milk protein was replaced with a modified soybean had weight gains and efficiencies similar to those of pigs fed the all-milk-protein diet, but incidence of scours decreased. Protein digestibility decreased as the level of soybean protein in the diet increased. These results suggest that 25 to 50% of the milk protein in a 28% protein milk replacer diet can be replaced with a modified soybean …

Rapid Id Of Diarrhea Causing K88 E. Coli (1981), K W. Mills, R M. Phillips, B L. Kelly, G L. Baughman
Kansas Agricultural Experiment Station Research Reports
The efficiency of the standard agglutination test, Y-1 mouse adrenal cell test, and infant-mouse gastric test was compared with a recently developed enzyme-linked immunosorbent assay (ELISA) for detecting the K88 pilus antigen and enterotoxin-producing E. coli. Isolates from clinical samples were identified on suspensions of bacteria. The sensitivity of the assay was in the nanogram-per-ml range as determined by measuring purified pili.; Swine Day, Manhattan, KS, November 12, 1981

Plasma And Milk Oxytetracycline Levels In Post Parturient Sows (1981), D Schoneweis, S Hummels, L Schulteis
Kansas Agricultural Experiment Station Research Reports
Plasma and milk samples were collected from three sows injected with LA 200 at 4 hours after injection and at 24-hour intervals thereafter. The single dose was calculated at 1 ml/22 pounds.; Swine Day, Manhattan, KS, November 12, 1981
Alfalfa Haylage For Sows During Gestation (1981), G L. Allee
Alfalfa Haylage For Sows During Gestation (1981), G L. Allee
Kansas Agricultural Experiment Station Research Reports
Digestion and nitrogen retention studies suggest that three pounds of good quality alfalfa haylage dry matter and two pounds of a grain, mineral, and vitamin premix will meet the nutritional requirements of sows during gestation. Quality of the haylage is extremely important for sows. Third-cutting alfalfa had a higher digestible energy and digestible protein than did the more mature first-cutting haylage. The digestible energy of alfalfa haylage for sows was 954 to 1,096 Kcal/pound. Sows fed alfalfa haylage and ONLY ONE pound of a grain vitamin and mineral premix farrowed pigs that were lighter at birth than pigs farrowed from …
Whey, Steam Rolled Or Whole Oats, And Fishmeal Or Meat And Bone Scraps For Weaned Pigs (1981), Robert H. Hines
Whey, Steam Rolled Or Whole Oats, And Fishmeal Or Meat And Bone Scraps For Weaned Pigs (1981), Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
In two feeding trials, the use of whey, steam rolled or ground oats, fishmeal or meat and bone scraps in starter diets for the weaned pig was evaluated. In Trial I, pigs fed the basal corn-soybean meal diet gained 5% slower than pigs fed diets containing 8.75% whey, with either 8.75% steam rolled or ground oats and 2.5% fishmeal or meat and bone scraps. The pounds of feed required per pound of gain were similar for all diets, resulting in the cheapest gain with the corn-soybean meal basal diet. In Trial II, 192 lighter pigs were used (13 to 24 …

The information is intended for producers, industry cooperators, and other interested persons.
The Toxicity Of Liquid Supplements Containing Urea, E.E. Bartley
The Toxicity Of Liquid Supplements Containing Urea, E.E. Bartley
Kansas Agricultural Experiment Station Research Reports
Liquid supplement manufacturers must provide a product that is effectively utilized and is nontoxic. Toxicity can be reduced if the supplement's pH is below 3.8, but low pH alone does not improve nutritive value. A good fermentable source of carbohydrate, like molasses or cooked starch, should be provided in adequate amount. When water or lignin sulfonates are substituted for good carbohydrate, urea utilization is reduced and the risk of toxicity is increased. Cattle that are hungry or starved from blizzard conditions or feed restriction are much more susceptible to ammonia toxicity than cattle kept full, so limit the availability of …
Performance And Carcass Traits Of Feeder Calves Scored For Muscling, Frame Size, And Condition, Dell M. Allen, Kenneth E. Kemp, Michael E. Dikeman
Performance And Carcass Traits Of Feeder Calves Scored For Muscling, Frame Size, And Condition, Dell M. Allen, Kenneth E. Kemp, Michael E. Dikeman
Kansas Agricultural Experiment Station Research Reports
Calves with different USDA frame sizes had similar carcass composition and quality when slaughtered within the recommended weight range for their frame size. Large-framed calves had higher dressing percentages and gained faster than medium- or small-framed calves. Condition score appeared more useful than muscling score to characterize calves' performance and carcass traits. Calves thin at weaning had poorer performance, lower marbling scores, less fat, and higher retail product percentages than calves in medium or fat condition at weaning. Medium condition calves gained faster, had less fat, higher retail product percentages, and lower marbling scores than fat calves. Calves with large …
Intermittent Feeding Of Chlortetracycline To Finishing Cattle, Jack G. Riley, Ronald V. Pope
Intermittent Feeding Of Chlortetracycline To Finishing Cattle, Jack G. Riley, Ronald V. Pope
Kansas Agricultural Experiment Station Research Reports
We used 168 yearling steers in a 139-day finishing trial to evaluate high levels of chlortetracycline (aureomycin) fed for short periods at regular intervals during finishing. Since liver abscess rate was low for all treatments including the nonmedicated controls and health status was good, chlortetracycline (CTC) did not significantly affect abscess rate or feedlot performance.
Effects Of Protein Level, Calcium:Phosphorous Ratio And Monensin On Performance Of Finishing Steers, S. Durham, Jack G. Riley, Ronald V. Pope
Effects Of Protein Level, Calcium:Phosphorous Ratio And Monensin On Performance Of Finishing Steers, S. Durham, Jack G. Riley, Ronald V. Pope
Kansas Agricultural Experiment Station Research Reports
Ration crude protein levels of 10.4% and 12.0% were fed with or without monensin and with calcium-to-phosphorous ratios (Ca:P) of 1:2, 2:1, or 1:1. Steers fed 10.4% crude protein, a 1:1 Ca:P, and Monensin had highest average daily gains and were most efficient. Extra protein in the 12% ration or the extra calcium in the 2:1 ration produced no benefits. Phosphorous in the 1:2 Ca:P apparently was excessive, as indicated by depressed daily gain and poorer efficiency. Monensin significantly increased average daily gain and improved feed efficiency.
Effect Of Compudose On Grazing Steers In Pasture, Then In Feedlot, L. Corah, Jack G. Riley, Ronald V. Pope
Effect Of Compudose On Grazing Steers In Pasture, Then In Feedlot, L. Corah, Jack G. Riley, Ronald V. Pope
Kansas Agricultural Experiment Station Research Reports
Steers implanted with an estradiol removable implant (Compudose) gained 14.8% faster during 121 days of grazing and 12.1% faster in the feedlot than control steers not implanted. Implanting improved feed efficiency 6.9% during finishing. Removing implants after grazing resulted in slowest and least efficient feedlot gains. Steers implanted only during the finishing phase gained the fastest and most efficiently in feedlot. Results of this 240-day test indicate that one implant stimulates performance at least 240 days

Nutritional Effects Of Beef Connective Tissue Characteristics And Eating Qualities, J.J. Wu, Melvin C. Hunt, Donald H. Kropf, Dell M. Allen, Curtis L. Kastner
Kansas Agricultural Experiment Station Research Reports
We compared taste panel and connective tissue characteristics of beef fed a high energy diet with beef fed grass. The high energy diet produced higher USDA quality and yield grades, more rapid weight gain, and increased connective tissue collagen synthesis arid breakdown. But, it did not consistently improve taste panel and shear characteristics over grass-feeding.

Short bursts of electricity (intermittent electrical stimulation) to beef carcasses accelerated pH decline and the onset of rigor mortis more than continuous stimulation did.
Factors Affecting Conception After Synchronization With Lutalyse® And Timed Insemination, M. King, G.H. Kiracofe, R.M. Mckee
Factors Affecting Conception After Synchronization With Lutalyse® And Timed Insemination, M. King, G.H. Kiracofe, R.M. Mckee
Kansas Agricultural Experiment Station Research Reports
With heifers given two injections of Lutalyse 11 days apart, and inseminated 80 hours after the second injection, only 20% in heat before 48 hours conceived compared with 65% that were in heat 48 to 80 hours after injection. Those showing heat early may have been inseminated too late. Heifers receiving their second injection on day 7. 8, or 9 of the cycle came into heat earlier than those injected on days 10 through 15.
Effect Of Limited Suckling On Reproductive Performance And Milk Production Of Cows And Weight Gains And Suckling Behavior Of Calves, Kenneth G. Odde, G.H. Kiracofe, R.R. Schalles
Effect Of Limited Suckling On Reproductive Performance And Milk Production Of Cows And Weight Gains And Suckling Behavior Of Calves, Kenneth G. Odde, G.H. Kiracofe, R.R. Schalles
Kansas Agricultural Experiment Station Research Reports
We used 109 Polled Hereford and percentage Simmental cows to evaluate limited suckling as an aid to induce cows to cycle after calving. Cows were allotted to: 1. once daily suckle; 2. twice daily suckle; 3. 48 hr calf removal (just before breeding season); and 4. controls (suckle ad libitum). Half of each group was implanted with Norgestomet 9 days before the breeding season. Limited suckling increased the number of cows showing estrus and conceiving early in the breeding season, and Norgestomet increased the percentage pregnant the first 21 days of the breeding season.

Use Of Kamar® Heatmount Detectors In Beef Cattle Synchronized With Lutalyse®, G.H. Kiracofe, M. Heekin, Kenneth G. Odde, M. King
Kansas Agricultural Experiment Station Research Reports
The ability of the Kamar Heatmount Detector to identify cows ready for insemination 80 hours after two Lutalyse injections was tested with 439 beef cows and heifers. The detector was placed on the rump at the second injection and was "read" at insemination. Conception rate from the 80-hour timed insemination for cows with red (activated) and lost detectors was 56.5% compared with 7.6% of the cows with white detectors.

Fifty percentage Simmental bull calves were fed either with or without Rumensin. Although Rumensin improved gain by 9.2%, it had no effect on sexual development.
The Effects Of Rumensin® And Two Levels Of Energy Prior To Calving On Reproductive Performance In First Calf Heifers, L.R. Sprott, L.R. Corah, Jack G. Riley, G.H. Kiracofe
The Effects Of Rumensin® And Two Levels Of Energy Prior To Calving On Reproductive Performance In First Calf Heifers, L.R. Sprott, L.R. Corah, Jack G. Riley, G.H. Kiracofe
Kansas Agricultural Experiment Station Research Reports
Heifers fed low energy diets gained less before calving, took longer from calving to first estrus, and dropped lighter calves. Their conception rates were lower and fewer showed estrus the first 20 days of breeding. Rumensin lengthened the time from calving to estrus with no effect on calf birth weight, milk production, or percentage of calves weaned. However, calves from heifers fed Rumensin gained faster. Long-term Rumensin feeding to heifers (from weaning through second breeding) increased weight gain and hastened puberty with no effect on reproductive performance. Rumensin-fed dams tended to wean heavier calves.
