Muscling Selection In Swine And Its Effect On Carcass Traits, J D. Wheat, Donald H. Kropf, Robert H. Hines Jan 1972

Muscling Selection In Swine And Its Effect On Carcass Traits, J D. Wheat, Donald H. Kropf, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

We are attempting to develop a well-muscled line of Durocs by selecting for minimum back fat and maximum loin eye area as estimated by the Anscan and to form a control line by randomly selecting from the same base population. The lines will be compared for performance and carcass traits, including incidence of pale soft exudative carcasses. Expected and realized heritability estimates for carcass traits will be calculated.; Swine Day, Manhattan, KS, November 2, 1972


Nutritional Adequacy Of Triticale For Finishing Swine, G L. Allee, Robert H. Hines Jan 1972

Nutritional Adequacy Of Triticale For Finishing Swine, G L. Allee, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

An experiment involving 81 finishing pigs was conducted to determine the nutritional adequacy of triticale for finishing swine. Pigs fed triticale alone gained significantly (P<.05) slower than pigs fed any other diets. Adding 0.1% L-lysine to triticale significantly (P<.05) increased daily gain. There were no significant differences in daily gain, feed intake, or feed:gain ratio between pigs fed triticale + lysine, triticale + soybean meal, milo + soybean meal or wheat + soybean meal. Differences in backfat thickness, loin-eye area, length or percentage of lean cuts in the carcass were not significant. Lysine is the first limiting amino acid in triticale for finishing swine. The lysine in triticale may not be totally available to pigs.; Swine Day, Manhattan, KS, November 2, 1972


Effects Of Flaked And Roasted Sorghum Grain On Finishing Swine Performance, G L. Allee, Robert H. Hines Jan 1972

Effects Of Flaked And Roasted Sorghum Grain On Finishing Swine Performance, G L. Allee, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

The value of feeding flaked or roasted sorghum grain to finishing swine (95 to 210 lbs.) was investigated using 54 barrows and gilts. Rate and efficiency of gain for each treatment group were similar. Data from this station indicate that processing methods like flaking or roasting sorghum grain do not improve the performance of finishing swine enough to offset the increased cost of processing.; Swine Day, Manhattan, KS, November 2, 1972


Amino Acid Supplementation Of Wheat And Milo For The Finishing Pig, G L. Allee, Robert H. Hines Jan 1971

Amino Acid Supplementation Of Wheat And Milo For The Finishing Pig, 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 loin eye area, and tended ...

Preventing Baby Pig Anemia Times Of Injection Compared, 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, B A. Koch, Robert H. Hines Jan 1971

Rations Containing Corn, Sorghum Grain, Or Wheat Compared For Weaned Pigs, 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


The Value Of Processing Sorghum Grain For Finishing Swine, B A. Koch, G L. Allee, Robert H. Hines Jan 1971

The Value Of Processing Sorghum Grain For Finishing Swine, 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 ...


Response Of Breeding And Gestating Sows To A Dietary Source Of Lactobacillus Acidophilus, B A. Koch, Robert H. Hines Jan 1971

Response Of Breeding And Gestating Sows To A Dietary Source Of Lactobacillus Acidophilus, 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, G L. Allee, Robert H. Hines Jan 1971

Effect Of Feeding Frequency On Performance Of Growing Pigs, 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, B A. Koch, Robert H. Hines Jan 1971

Response Of Growing And Finishing Swine To A Dietary Source Of Lactobacillus Acidophilus, 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 ...


Evaluation Of L-Lysine Fortified Bulgar Millfeed For Finishing Swine, B A. Koch, Robert H. Hines Jan 1971

Evaluation Of L-Lysine Fortified Bulgar Millfeed For Finishing Swine, 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


Influence Of Fat Level And Calorie:Protein Ratio On The Performance Of Young Pigs, G L. Allee, Robert H. Hines Jan 1971

Influence Of Fat Level And Calorie:Protein Ratio On The Performance Of Young Pigs, 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 ...


Full-Fat Soybeans For Growing-Finishing Swine, D T. Lafferty, Robert H. Hines Jan 1971

Full-Fat Soybeans For Growing-Finishing Swine, 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 ...


Evaluation Of Antibacterial Agents To Improve Growth Rate And Efficiency Of Weaned Pigs, G L. Allee, Robert H. Hines Jan 1971

Evaluation Of Antibacterial Agents To Improve Growth Rate And Efficiency Of Weaned Pigs, 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, G L. Allee, Robert H. Hines Jan 1971

Reconstituted Sorghum Grain For Finishing Swine, 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


Growth Of Mixed And Intact Litters Compared, B A. Koch, Robert H. Hines Jan 1970

Growth Of Mixed And Intact Litters Compared, B A. Koch, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Mixing litters after weaning did not significantly affect rate of gain or efficiency of growing pigs. Weight gains were similar (1.57 or 1.49) for mixed litters and intact litters during a 28-day post-weaning trial.; Swine Day, Manhattan, KS, October 1, 1970


Processed Whole Soybeans In Growing-Finishing Rations, B A. Koch, D T. Lafferty, Robert H. Hines Jan 1970

Processed Whole Soybeans In Growing-Finishing Rations, B A. Koch, D T. Lafferty, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

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


Mechanical Baby Pig Feeder, Robert H. Hines Jan 1970

Mechanical Baby Pig Feeder, 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


Wheat In Growing-Finishing Rations, B A. Koch, Robert H. Hines Jan 1970

Wheat In Growing-Finishing Rations, 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 ...

Kansas Agricultural Experiment Station Research Reports

Three trials were conducted involving 231 head of pigs to determine the efficiency of various methods of providing supplemental iron to baby pigs. All treatment groups were effective in maintaining normal hematocrit values with no symptoms of baby pig anemia. Weight gains were similar in all trials.; Swine Day, Manhattan, KS, October 1, 1970


Evaluation Of Dried Skim Milk, Dried Whey, And Fat In Pig Starters, J G. Stuart, B A. Koch, Robert H. Hines Jan 1970

Evaluation Of Dried Skim Milk, Dried Whey, And Fat In Pig Starters, 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 ...

Waste Disposal By Aerobic Oxidation, B A. Koch

Kansas Agricultural Experiment Station Research Reports

Waste disposal and odor control are two important problems in pork production. The odor formerly was called the "money smell" has suddenly become "Environmental Pollution." Concentrating many animals in small areas compounds the problem.; Swine Day, Manhattan, KS, October 1, 1970


Use Of Diallel Matings To Estimate Maternal Effects And General And Specific Combining Abilities In Swine, J D. Wheat, T Yu, R R. Schalles Jan 1970

Use Of Diallel Matings To Estimate Maternal Effects And General And Specific Combining Abilities In Swine, 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 ...


Comparison Of Pork Carcass Evaluation Procedures, D Stiffler, Donald H. Kropf Jan 1970

Comparison Of Pork Carcass Evaluation Procedures, 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


Corn Or Sorghum Grain In Growing-Finishing Rations (With And Without Added Copper, Vitamin E, Biotin Or Aureo Sp-250), B A. Koch, Robert H. Hines Jan 1970

Corn Or Sorghum Grain In Growing-Finishing Rations (With And Without Added Copper, Vitamin E, Biotin Or Aureo Sp-250), 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 ...


Methods Of Preventing Baby Pig Anemia Compared, B A. Koch, Robert H. Hines Jan 1969

Methods Of Preventing Baby Pig Anemia Compared, B A. Koch, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

Anemia as it most frequently occurs in baby pigs usually is caused by an iron deficiency. Iron stored in a baby pig is extremely limited and is quickly used to produce hemoglobin to maintain oxygen-carrying capacity in the blood. Supplemental iron is needed almost immediately since the quantity of iron received from sow's milk is extremely small.; Swine Day, Manhattan, KS, September 25, 1969


Ddvp (Shell Dichlorvos) For Pregnant Sows, B A. Koch, Robert H. Hines Jan 1969

Ddvp (Shell Dichlorvos) For Pregnant Sows, B A. Koch, Robert H. Hines

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 ...


Low-Level Antibiotics In Growing-Finishing Swine Rations., B A. Koch, Robert H. Hines Jan 1969

Low-Level Antibiotics In Growing-Finishing Swine Rations., 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

Effect Of Oxytocin On Parturition In Sows, G H. Kiracofe, Robert H. Hines

Kansas Agricultural Experiment Station Research Reports

The hormone oxytocin (a hypothalamic neurosecretion that is stored in the posterior pituitary gland) stimulates' uterine contractions during natural parturition. Commerical oxytocin has been used to induce labor or to intensify uterine contractions during difficult or prolonged labor in sows. This test evaluated use of one level of a commercial oxytocin during normal parturition.; Swine Day, Manhattan, KS, September 25, 1969
