Preventing Baby Pig Anemia, Times Of Injection Compared (1971), D A. Schoneweis, R K. Bartel, J G. Stuart, Robert H. Hines
Preventing Baby Pig Anemia, Times Of Injection Compared (1971), D A. Schoneweis, R K. Bartel, J G. Stuart, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Fourteen litters (120 pigs) were used to study effects of iron injections on day one or day four after birth. No differences were detected in weight gains, hematological values of hemoglobin, packed cell volume, or red blood-cell count. The results indicate that injectable iron dextran may be administered on day one along with other husbandry practices (dipping navel cords, clipping needle teeth, ear notching) with no adverse effects. A disadvantage would be iron lost in pigs that die before day four from crushing, inanition, etc.; Swine Day, Manhattan, KS, October 7, 1971
Rations Containing Corn, Sorghum Grain, Or Wheat Compared For Weaned Pigs (1971), B A. Koch, Robert H. Hines
Rations Containing Corn, Sorghum Grain, Or Wheat Compared For Weaned Pigs (1971), B A. Koch, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
The feed, required per pound of gain was similar for pigs fed corn, sorghum grain, corn-wheat, or sorghum grain-wheat diets. Pigs on the corn ration grew significantly (P<.05) faster. The sorghum grain, sorghum grain-wheat, and corn-wheat rations each produced similar gains.; Swine Day, Manhattan, KS, October 7, 1971
Evaluation Of L-Lysine Fortified Bulgar Millfeed For Finishing Swine (1971), B A. Koch, Robert H. Hines
Evaluation Of L-Lysine Fortified Bulgar Millfeed For Finishing Swine (1971), B A. Koch, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
A growing-finishing ration that substituted 25% L-lysine fortified bulgar millfeed for 20% of the sorghum grain and 5% of soybean meal' (44%) gave weight gains and feed:gain ratios for finishing swine similar to those with the control ration. But pigs receiving rations with the 25% bulgar millfeed replacing 15% of the sorghum grain and 10% of the soybean meal gained significantly (P<.0l) slower and 25% less efficiently, so we did not evaluate using more than 25% of the bulgar mil1feed in rations for finishing swine.; Swine Day, Manhattan, KS, October 7, 1971
The Value Of Processing Sorghum Grain For Finishing Swine (1971), B A. Koch, G L. Allee, Robert H. Hines
The Value Of Processing Sorghum Grain For Finishing Swine (1971), B A. Koch, G L. Allee, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Three feeding trials were conducted to determine benefits of processing sorghum grain (milo) for finishing swine. Flaked, ground, and dry rolled milo rations resulted in similar pig weight gains. Generally, the feed:gain ratios of pigs receiving steam-flaked rations were slightly better than ratios of pigs receiving ground or dry rolled grain. Pigs receiving a popped ration grew significantly slower and less efficiently than pigs receiving ground or flaked rations. Grinding the popped ration increased average daily feed intake and average daily gain, but the feed:gain ration did not improve. Finishing swine can be fed steam-flaked milo very satisfactorily; however, the …
Influence Of Fat Level And Calorie:Protein Ratio On The Performance Of Young Pigs (1971), G L. Allee, Robert H. Hines
Influence Of Fat Level And Calorie:Protein Ratio On The Performance Of Young Pigs (1971), G L. Allee, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
One hundred twenty-eight pigs averaging 44 pounds were used to determine the influence of level of dietary fat and calorie:protein ratio on the performance of young pigs. Daily gains by pigs fed diets containing 0, 3, 6, 9, or 12% added fat did not differ significantly. Feed efficiency and kcal metabolizable energy per pound of gain were improved as the fat level of the diet increased. When fat was added to the diet without adjusting the calorie: protein ratio, average daily gain and energy efficiency were significantly reduced. Thus, suggesting the importance of the. calorie:protein ratio in the nutrition of …

Evaluation Of Antibacterial Agents To Improve Growth Rate And Efficiency Of Weaned Pigs (1971), G L. Allee, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Pigs medicated 5 weeks with TNA-290 and ASP-250 had statistically greater (P<.05) average daily gains and those medicated with ASP-250 had significantly (P<.05) lower feed conversion rations than non-medicated pigs. Feed efficiency, feed consumption, or average daily gain among pigs medicated with Furox, ASP-250, or TNA-290 did not differ significantly.; Swine Day, Manhattan, KS, October 7, 1971
Reconstituted Sorghum Grain For Finishing Swine (1971), G L. Allee, Robert H. Hines
Reconstituted Sorghum Grain For Finishing Swine (1971), G L. Allee, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Gains of finishing pigs fed whole or rolled reconstituted sorghum grain (30% moisture) from 100 lbs. to an average of 210 lbs. were similar and similar to gains by pigs fed a ground sorghum grain ration. Compared on a 90% dry matter basis, pigs fed the ground ration were 7% more efficient than pigs fed the whole or reconstituted grain rations. Rolling the reconstituted sorghum grain improved feed efficiency (8%) and improved rate of gain as compared to the performance of pigs fed the whole reconstituted grain.; Swine Day, Manhattan, KS, October 7, 1971
Amino Acid Supplementation Of Wheat And Milo For The Finishing Pig (1971), G L. Allee, Robert H. Hines
Amino Acid Supplementation Of Wheat And Milo For The Finishing Pig (1971), G L. Allee, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Two experiments involving 214 pigs were conducted to evaluate milo and wheat as the sole sources of amino acids for finishing swine, and the effects of supplementing these grains with lysine and methionine. Without supplemental lysine wheat and milo diets were inadequate for finishing pigs as measured by growth rate, feed efficiency, and loin eye area. There were no significant differences in daily gain or feed efficiency among the pigs fed wheat + lysine, milo + lysine + methionine, wheat + soybean meal or milo + soybean meal. Pigs fed milo supplemented with only lysine gained slower, had a smaller …

Response Of Breeding And Gestating Sows To A Dietary Source Of Lactobacillus Acidophilus (1971), B A. Koch, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
During the breeding period, adding the fermentation product (lactobacillus acidophilus) to the ration fed to gilts and sows made no difference in conception percentages. Nonsignificant differences was observed between the control group and the group receiving the additive in number of pigs born dead or alive and weight of pigs at 2 or 4 weeks of age.; Swine Day, Manhattan, KS, October 7, 1971
Effect Of Feeding Frequency On Performance Of Growing Pigs (1971), G L. Allee, Robert H. Hines
Effect Of Feeding Frequency On Performance Of Growing Pigs (1971), G L. Allee, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
The influence of frequency of feeding on weight gain, feed efficiency, and carcass measurements was investigated, using 48 pigs averaging 40 pounds. Differences in daily gain among pigs fed ad libitum, twice a day or once a day were not significant. However, pigs fed only once/48 hours gained significantly (P<.05) slower than pigs on the other treatments. Pigs allowed access to feed once/24 hrs. or once/48 hrs. were more efficient (P<.05) in feed utilization than pigs fed twice/ 24 hrs. or those fed ad libitum. Carcass measurements did not differ significantly among pigs fed ad libitum, twice/ 24 hrs., or once/24 hrs. Pigs allowed access to feed only once/48 hrs. had significantly (P<.05) less backfat and smaller loin eye areas than pigs fed more frequently.; Swine Day, Manhattan, KS, October 7, 1971
Response Of Growing And Finishing Swine To A Dietary Source Of Lactobacillus Acidophilus (1971), B A. Koch, Robert H. Hines
Response Of Growing And Finishing Swine To A Dietary Source Of Lactobacillus Acidophilus (1971), B A. Koch, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Post-weaning comparisons were made using high and low protein rations with and without a fermentation product (lactobacillus acidophilus). Pigs receiving higher protein rations (18%) grew slightly faster than those receiving low protein (15%) rations; however, the differences were not significant. Adding a fermentation product to either ration tested did not significantly improve performance of weaned pigs. Finishing swine were used to compare high-protein (16%) ration and low-protein (13%) rations with and without the fermentation product. Pigs receiving the higher-protein ration grew significantly faster than those receiving the lower-protein ration with or without the additive. Pigs receiving the additive in the …
Full-Fat Soybeans For Growing-Finishing Swine (1971), D T. Lafferty, Robert H. Hines
Full-Fat Soybeans For Growing-Finishing Swine (1971), D T. Lafferty, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Pigs fed full-fat, processed soybeans (FFPS) in place of soybean meal (SBM, 44% CP) gained adequately and produced carcasses with lean measurements equal to those of pigs fed soybean meal. Backfat and belly fat were considerably softer on carcasses of pigs fed FFPS, and total fat content of loin eye muscle was greater in FFPS carcasses than in carcasses of pigs fed SBM. Taste panel observations showed no differences in flavor, juiciness, tenderness or over-all acceptability of pork chops produced by either diet. Barrows gained faster than gilts regardless of treatment and barrows had firmer carcasses. Gilt carcasses had a …
Use Of Diallel Matings To Estimate Maternal Effects And General And Specific Combining Abilities In Swine (1970), J D. Wheat, T Yu, R R. Schalles
Use Of Diallel Matings To Estimate Maternal Effects And General And Specific Combining Abilities In Swine (1970), J D. Wheat, T Yu, R R. Schalles
Kansas Agricultural Experiment Station Research Reports
As early as 1926, Danish workers reported that cross-breeding gave larger litters at weaning that gained faster on less feed per pound of gain. Crossbreeding is now used extensively in market hog production. It uses heterosis that results from hybrid combinations. Heterosis (superiority of crossbred progeny over the average of their parents) may be evaluated in terms of a high general combining ability, the capacity to cross well in several crosses, and specific combining ability, the ability to "nick" or cross particularly well with certain other strains, but not with all. Strains that "nick" well are said to have specific …
Evaluation Of Dried Skim Milk, Dried Whey, And Fat In Pig Starters (1970), J G. Stuart, B A. Koch, Robert H. Hines
Evaluation Of Dried Skim Milk, Dried Whey, And Fat In Pig Starters (1970), J G. Stuart, B A. Koch, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Five starters were compared with a corn-soybean meal standard with 15% skim milk and 12% sugar. Rations containing dried skim milk or dried whey with 3 or 5% added edible fat also were compared. The rations were offered to suckling baby pigs from 2 to 4 weeks (phase 1) and again during 6 to 10 weeks of age (phase 2). During phase 1, neither feed intake nor total gain differed significantly. During phase 2 all rations produced similar weight gains and feed intake. Feed efficiency favored rations containing dried skim milk and 3 or 5% added fat. Rations containing more …
Comparison Of Pork Carcass Evaluation Procedures (1970), D Stiffler, Donald H. Kropf
Comparison Of Pork Carcass Evaluation Procedures (1970), D Stiffler, Donald H. Kropf
Kansas Agricultural Experiment Station Research Reports
Carcass data were obtained from 28 barrows from the Kansas Swine Testing Station and 31 from the Kansas State Barrow Contest in 1969. All were slaughtered and standard measurements taken. Each carcass was cut to wholesale cuts by the conventional K.S.U. lab method. Cut-out data were used to calculate ham-loin index, four lean-cut percentages (live and carcass weight), percent ham plus loin of live and carcass weight, and dollar value of five wholesale cuts per hundred weight of carcass.; Swine Day, Manhattan, KS, October 1, 1970

This progress report covers only growth rate and feed efficiency of pigs the first 73 days of one feeding trial. Replacing soybean meal with either dry-roasted whole soybeans or pressure-extruded, whole soybeans did not significantly affect rate of growth or feed efficiency. Results were similar when the replacement was on a pound-for-pound basis or a protein-unit basis. Also, results were similar with rations in pellet or meal form. Pelleted rations were 2 to 14% more efficient than meal rations. Barrows gained 8% faster than gilts.; Swine Day, Manhattan, KS, October 1, 1970

Corn Or Sorghum Grain In Growing-Finishing Rations (With And Without Added Copper, Vitamin E, Biotin Or Aureo Sp-250) (1970), B A. Koch, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Pigs fed corn gained faster than those fed sorghum grain in one trial. The reverse was true in a second trial. Overall average daily gain figures were almost identical (1.67 lbs. per day for corn; 1.65 lbs. per day for sorghum). Average feed efficiency favored corn slightly (3.03 to 3.10). Adding 250 ppm copper to the diet significantly increased weight gain in one of five trials. Adding either vitamin E, biotin, or Aureo SP-250 did not significantly increase average daily gain or improve feed efficiency. Barrows gained 15% faster than gilts. Crossbred pigs gained 8% faster than the average of …

Wheat In Growing-Finishing Rations (1970), B A. Koch, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Varying percentages of wheat replaced sorghum grain in rations for growing pigs in two trials. There were no significant differences in performance of pigs in trial one. In trial two significant differences unrelated to wheat in the diet occurred. Average feed efficiency for all groups receiving no wheat (100% sorghum) was 3.13 pounds. Average feed efficiency for all groups receiving no sorghum grain (100% wheat) was 3.31 pounds. Barrows gained 9% faster than gilts. Pelleting the ration saved an average of 49 pounds of feed for every 100 pounds of gain (17%).; Swine Day, Manhattan, KS, October 1, 1970

Mechanical Baby Pig Feeder (1970), Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Various types of mechanical units designed to replace lactating brood sows are available. The Mini-Mor Corporation, Omaha, Nebraska, lent Kansas State University a unit designed to raise 36 pigs in individual cages. We are not trying to replace the lactating sow but to save baby pigs when they lose their mothers, or when a sow has more pigs than teats. The unit also could be used with large litters, for pigs that are pushed back and obviously are not getting enough to eat when a few days old.; Swine Day, Manhattan, KS, October 1, 1970

Kansas Agricultural Experiment Station Research Reports
Recent reports indicate that a low level (25 parts per million of active ingredient) of 2,2 dichlorovinyl dimethyl phosphate (DDVP) increases growth of weanling pigs. The trial reported here was designed to measure such response in pigs from Dichlorvos-fed sows and also in pigs from sows not receiving Dichlorvos during late pregnancy.; Swine Day, Manhattan, KS, September 25, 1969
Lysine Supplementation For Growing-Finishing Swine Rations (1969), B A. Koch, Robert H. Hines
Lysine Supplementation For Growing-Finishing Swine Rations (1969), B A. Koch, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
The protein level and protein quality of swine rations consisting primarily of grain can be changed by adding either protein like soybean meal or individual amino acids like lysine. Protein requirements are based on individual amino acids that compose the protein. Amino acid most lacking in grain proteins is lysine, so lysine is the most limiting amino acid in growing-finishing rations made up primarily of grain. Feeding trials reported here were designed to: (1) compare corn and sorghum grain, (2) determine the value of 0.1% of lysine added to the ration, (3) compare performance of barrows and gilts and (4) …

This study compared various methods of evaluating carcasses. Data from 57 barrows on feeding trials for a barrow contest at the 1968 Kansas State Fair in Hutchinson were used.The barrows went on test weighing approximately 50 pounds each and were taken off feed individually at 200- 220 pounds, held off feed over night and slaughtered at the Kansas State University Meats Laboratory. Live weight was determined immediately before slaughter and carcass weight, after a 24-hour chill. Cutting time ranged from 24 to 120 hours post-mortem.; Swine Day, Manhattan, KS, September 25, 1969

Kansas Agricultural Experiment Station Research Reports
Baby pigs have the ability to grow rapidly and efficiently. Creep rations at an early age enhance their potential. Most commercial creep rations contain feedstuffs to increase palatability and acceptability. Are these ingredients necessary or will rather simple starters produce similar gains? Five starters were compared, varying from a simple corn-milo- soybean meal ration to a ration containing several palatability aiding ingredients--from 10 days of age to weaning at 28-35 days; and from 6 weeks to 10 weeks of age.; Swine Day, Manhattan, KS, September 25, 1969

Low-Level Antibiotics In Growing-Finishing Swine Rations (1969), B A. Koch, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
The new K-State facilities for growing-finishing swine seemed ideal to re-evaluate various antibiotics as low-level feed additives. The first trial reported here was with the first pigs fed in the new barn. They also were the first farrowed in the new farrowing house, and the first raised in the new nursery. The trials were designed to: (1) compare rations with and without an antibiotic at a low level, (2) various antibiotics and combinations of antibiotics and (3) to determine the need for extra feeder space.; Swine Day, Manhattan, KS, September 25, 1969

Kansas Agricultural Experiment Station Research Reports
Most recent laboratory and research station reports have indicated that 2,2 - dichlorovinyl dimethyl phosphate (DDVP) (Shell Dichlorvos) fed at low levels to pregnant sows in late gestation favorably affects newborn pigs. A field study we reported last year showed no favorable effect among over 200 litters. More than 600 barrows were checked at slaughter and no difference was detected in slaughter age between pigs from treated or untreated sows. Trials reported here involve sows and gilts in the K-State research swine herd. Trial 1 was those farrowing in March; trial 2, those farrowing in May.; Swine Day, Manhattan, KS, …
Ten-Year Summary Of K.S.I.A. Swine Testing Station Data, Robert H. Hines
Ten-Year Summary Of K.S.I.A. Swine Testing Station Data, Robert H. Hines
Kansas Agricultural Experiment Station Research Reports
Swine testing stations "performance prove" breeding lines for genetic progress in the swine industry. The phenotype of a boar is a combination of his genetic ability and environment (nutrition, health, and etc.). Thus by using central test stations where all pigs are housed in similar pens and fed the same rations, the effect of environment is reduced so the genetic ability is more accurately appraised. The Kansas Swine Testing Station first tested hogs for Kansas Breeders the fall of 1958. Since then about 100 breeders have participated in the test station.; Swine Day, Manhattan, KS, September 25, 1969
