Item Open Access Amino acid supplementation of wheat and milo for the finishing pig(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:40:55Z) Allee, G.L.; Hines, Robert H.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 to be less efficient in feed utilization than the pigs fed milo + soybean meal. The results indicate that lysine is the only limiting amino acid in wheat for the finishing pig, while milo must be supplemented with both lysine and methionine.Item Open Access Response of breeding and gestating sows to a dietary source of lactobacillus acidophilus(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:34:22Z) Koch, B.A.; Hines, Robert H.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.Item Open Access Preventing baby pig anemia times of injection compared(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:34:07Z) Schoneweis, D.A.; Bartel, R.K.; Stuart, J.G.; Hines, Robert H.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.Item Open Access Effect of feeding frequency on performance of growing pigs(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:33:56Z) Allee, G.L.; Hines, Robert H.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.Item Open Access Rations containing corn, sorghum grain, or wheat compared for weaned pigs(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:32:46Z) Koch, B.A.; Hines, Robert H.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.Item Open Access Response of growing and finishing swine to a dietary source of lactobacillus acidophilus(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:32:36Z) Koch, B.A.; Hines, Robert H.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 13% ration grew slightly faster than pigs receiving the 13% ration without the additive.Item Open Access Evaluation of L-Lysine fortified bulgar millfeed for finishing swine(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:32:25Z) Koch, B.A.; Hines, Robert H.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.Item Unknown The value of processing sorghum grain for finishing swine(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:32:06Z) Koch, B.A.; Allee, G.L.; Hines, Robert H.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 cost of processing the milo more than offset the advantages in feed efficiency.Item Unknown Influence of fat level and calorie:protein ratio on the performance of young pigs(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:31:54Z) Allee, G.L.; Hines, Robert H.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 young pigs. Current prices make fat an economical source of energy for young pigs.Item Unknown Full-fat soybeans for growing-finishing swine(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:31:42Z) Lafferty, D.T.; Hines, Robert H.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 larger percentage of lean cuts, more loin eye area, more length, less backfat, and higher ham-loin indexes than barrow carcasses regardless of treatment.Item Unknown Evaluation of antibacterial agents to improve growth rate and efficiency of weaned pigs(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:31:29Z) Allee, G.L.; Hines, Robert H.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.Item Open Access Reconstituted sorghum grain for finishing swine(Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-05-07T21:31:00Z) Allee, G.L.; Hines, Robert H.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.
