Effects Of Level Of Modified Tall Oil On Finishing Pig Growth Performance And Carcass Characteristics (1998), P R. O'Quinn, J C. Woodworth, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband, John A. Unruh

Kansas Agricultural Experiment Station Research Reports

A growth trial was conducted to evaluate effects of increasing levels of modified tall oil (MTO) on growth performance and carcass composition of finishing barrows. No effect of treatment was observed for ADG, ADFI, or feed efficiency (F/G) during any of the growth periods. However, pigs fed increasing MTO had less backfat, larger longissimus muscle area, and increased percentage muscle than control pigs not fed MTO. Additionally, carcasses from pigs fed MTO had decreased drip loss. The results of this trial indicate that although MTO has no impact on growth performance in barrows, it can improve carcass leanness. The optimal …

Kansas Agricultural Experiment Station Research Reports

In nursery pigs, the greatest digestibilities of DM, N, and OE were observed with soft sorghum. In finishing pigs, no difference was observed in digestibility of nutrients among the sorghum genotypes. Chicks fed soft sorghum had better F/G than chicks fed medium and hard sorghum. Finally, thermal processing (steam flaking and extrusion) improved ADG and F/G and digestibilities of DM, N, and GE compared to grinding (coarse and fine).; Swine Day, Manhattan, KS, November 19, 1998

Added Dietary Fat Improves Growth Performance And Feed Efficiency In Growing-Finishing Pigs Under Commercial Conditions (1998), S S. Dritz, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen Jan 1998

Added Dietary Fat Improves Growth Performance And Feed Efficiency In Growing-Finishing Pigs Under Commercial Conditions (1998), S S. Dritz, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

A total of480 pigs was used in an experiment conducted in a commercial research facility to determine the influence of fat additions to the growing-finishing diet on pig performance and carcass composition. Adding fat to the diet from 80 to 265 lb increased ADG and FIG by 1 and 2%, respectively, for each 1%added fat. The growth response was greatest during the initial phase of the trial (80 to 130 lb) and declined as the trial progressed. The feed efficiency response was consistent throughout the trial. After adjusting for the greater carcass weight of pigs consuming the high fat diets, …

Effects Of Poultry Fat And Choice White Grease On Pork Longissimus Muscle, Belly, And Bacon Quality (1998), J J. Engel, J W. Smith Ii, Robert D. Goodband, John A. Unruh, Michael D. Tokach, Jim L. Nelssen Jan 1998

Effects Of Poultry Fat And Choice White Grease On Pork Longissimus Muscle, Belly, And Bacon Quality (1998), J J. Engel, J W. Smith Ii, Robert D. Goodband, John A. Unruh, Michael D. Tokach, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

Eighty-four crossbred gilts were used to examine the effects of increasing dietary additions of poultry fat (PF) or choice white grease (CWG) on longissimus muscle (LM), belly, and bacon quality. Pigs fed PF had greater LM cooking loss values than those fed CWG. As PF increased in the diet, LM Minolta L* and belly lean values decreased. then increased. Neither fat source nor level significantly affected other LM quality or sensory traits. As PF increased, bacon slicing score decreased. Although all taste panel scores were well within acceptable ranges, bacon from pigs fed PF had higher sensory panel "off flavor" …

Influence Of Duration Of Dietary Vitamin E Supplementation On Fresh And Cured Pork Color Stability (1998), J F. Stika, John A. Unruh, Donald H. Kropf, Melvin C. Hunt, Robert D. Goodband Jan 1998

Influence Of Duration Of Dietary Vitamin E Supplementation On Fresh And Cured Pork Color Stability (1998), J F. Stika, John A. Unruh, Donald H. Kropf, Melvin C. Hunt, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

Supplementing finishing pigs genetically predisposed to lipid deposition with atocopheryl acetate above 12 IU/lb of feed for as long as 70 d did not improve color stability of fresh and cured pork. Tissue a-tocopherol levels were similar across dietary treatments and higher than predicted. Muscle accumulation of a-tocopherol may be related to the rate and extent of lipid deposition in muscle. Also, chill temperature and carcass chill rate variability, under spray chill conditions, did not influence fresh pork color stability when carcasses with excessive amounts of external fat were utilized.; Swine Day, Manhattan, KS, November 19, 1998

Influence Of Duration Of Dietary Vitamin E Supplementation On Swine Growth Performance And Carcass Quality (1998), J F. Stika, John A. Unruh, Donald H. Kropf, Melvin C. Hunt, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

Supplementing medium-lean genotype pigs with supranutritional concentrations of dietary vitamin E (91 IU d-a-tocopheryl acetate/lb of feed) for as long as 70 d during the finishing phase was not effective in improving swine performance, feeding characteristics, and 24 h loin muscle quality. However, lower carcass temperatures obtained by spray chilling pork sides at O°C versus 4.4°C had a beneficial effect on 24 h carcass quality by improving marbling and lean firmness scores and reducing loin muscle moisture exudate. Overall, 24 h pork carcass quality was impacted more by chill rate than dietary vitamin E supplementation.; Swine Day, Manhattan, KS, November …

Effects Of Whole Grain And Distillers Dried Grains With Solubles From Normal And Heterowaxy Endosperm Sorghums On Growth Performance, Nutrient Digestibility, And Carcass Characteristics Of Finishing Pigs (1998), B W. Senne, Robert H. Hines, D W. Dean, I Mavromichalis, J R. Froetschner, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

No differences occurred in ADG, ADFI, F/G, digestibilities of DM and GE, dressing percentage, 10th rib fat depth, or fat free lean index in pigs fed normal vs heterowaxy sorghums. As anticipated, with the greater fiber and lower energy in distillers dried grains with solubles (DDGS) than the parent cereal grains, ADG and digestibilities of DM and GE were lower and F/G was worse for pigs fed DDGS. However, the energy value of the DDGS was affected less adversely when heterowaxy sorghum was used for fermentation to ethanol.; Swine Day, Manhattan, KS, November 19, 1998

Kansas Agricultural Experiment Station Research Reports

Results of these studies suggest that experimental high molecular weight, whey protein concentrate can be an effective replacement for spray-dried animal plasma in diets for weanling pigs. Increasing spray-dried animal plasma improved ADG and ADFI quadratically, with the maximum response observed with 2.5% in 21-d-old pigs or 5.0% in 12-d-old pigs. The specialty whey protein concentrate fed from d 0 to 14 after weaning resulted in similar responses as spray-dried animal plasma fed during the same period and may be an effective alternative.; Swine Day, Manhattan, KS, November 19, 1998

Effects Of Inorganic And Organic Acids On Urine Ph In Lactating Sows (1998), Robert H. Hines, H Coa, D J. Lee, C A. Maloney, J S. Park, Joel M. Derouchey, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

Some swine practitioners are advocating the use of dietary acidifiers to reduce urine pH and, thereby, reduce the incidence of urinary tract infections. In our experiment, sows fed an inorganic (phosphoric) acid had lower urine pH than sows fed diets with organic (fumaric, lactic, formic, propionic, and citric) acids. Indeed, the organic acids at 1.5% and 3.0% of the diet increased blood pH and decreased pC02,indicating that these sows were in a more alkalotic (not acidotic) state.; Swine Day, Manhattan, KS, November 19, 1998

Phosphorus-Reducing Technologies In Swine Production (1998), Michael A. Boland, K A. Foster, P V. Preckel

Kansas Agricultural Experiment Station Research Reports

Soil phosphorus levels have increased as swine production has become concentrated. Phosphorus-based manure management regulations for land application have been proposed by policy makers. The objective of this research was to determine benefits/costs of adopting phytase for reducing phosphorus. Results were derived using different manure storage and application systems. Although phytase was a least-cost ingredient, it became profitable when producers were constrained by land. Land requirements were 2 to 5 times greater under a phosphorus application regulation than a nitrogen application regulation.; Swine Day, Manhattan, KS, November 19, 1998

Kansas Agricultural Experiment Station Research Reports

Talc did not affect growth performance, carcass characteristics, or stomach ulceration in finishing pigs. Feeder bridging scores and coefficients of static force (the force needed to result in particle movement) were increased with added talc, both of which indicate reduced feed flowability. In a second experiment, reducing particle size from 1,050 microns to 450 microns increased the coefficients of static force, dynamic force, and angle of repose. Adding talc to either particle size diet did not improve feed flow characteristics.; Swine Day, Manhattan, KS, November 19, 1998

Kansas Agricultural Experiment Station Research Reports

Three hundred and sixty early-weaned barrows were fed diets containing increasing levels of added Zn from zinc oxide (0, 50, 100, 200, 400, 800, 1,600, 2,400, and 3,200 ppm). From d 11 to 21, growth performance improved with up to 100 ppm of added Zn but was not improved further until pigs were fed 3,200 ppm of added Zn. From d 21 to 36, pigs fed 100 ppm of Zn had the best growth performance. These results suggest that a pig's basal Zn requirement is met with 100 ppm of added Zn from zinc oxide, but adding 3,200 ppm Zn …

Influence Of Spirulina Platensis On Growth Performance Of Weanling Pigs (1998), G S. Grinstead, J Sawyer, K Maxwell, R Stott, A Moser, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

We conducted three experiments to evaluate the influence of an algal feed additive, Spirulina platensis, on weanling pig performance. Two experiments conducted under commercial production conditions indicated a response to Spirulina platensis in meal-based diets but not pelleted diets. Another experiment concluded that Spirulina platensis tended to improve F/G early in the trial but not for cumulative performance. Results of these three experiments suggest that Spirulina platensis added at low inclusions to the diet may enhance performance. However, the results lacked consistency across experiments and warrant further investigation.; Swine Day, Manhattan, KS, November 19, 1998

Compared to a corn-soybean meal control, added-fat from tallow, soybean oil, and dry-extruded whole soybeans (DEWS) improved ADG, F/G, and digestibility of DM and N. Feeding tallow increased belly firmness but also increased backfat thickness compared to diets with soy oil and DEWS. Comparisons among soybean genotypes indicated that high oleic acid soybeans supported greater growth performance than soybeans with high palmitic acid content. However, soybean genotype had no effect on carcass or meat quality measurements.; Swine Day, Manhattan, KS, November 19, 1998

Also, inclusion of .2% yeast product resulted in a greater rate of gain and a trend for improved feed efficiency in weanling pigs.; Swine Day, Manhattan, KS, November 19, 1998

Pellet durability index was greatest when animal protein products (dried whey, fish meal, spray-dried blood cells, and a porcine coproduct) were used in place of soybean meal. However, no differences occurred in ADG, ADFI, or F/G among segregated early-weaned piglets (10.1 lb) fed the various protein sources.; Swine Day, Manhattan, KS, November 19, 1998
