Determining Feed Budgets For Farm-Specific Nutritional Programs, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz Jan 1998

Determining Feed Budgets For Farm-Specific Nutritional Programs, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Use of feed budgets simplifies feed delivery and improves the accuracy of delivering diets to the correct pig weight ranges during the nursery and finishing periods. Little information has been available for determining farm-specific feed budgets in the past. In this paper, we will outline simple methods to customize a feed budget for individual farms using feed efficiency from past closeout records.; Swine Day, Manhattan, KS, November 19, 1998

Effects Of An Enteric Disease Challenge On Growth, Nitrogen Retention, And Immune Status Indicators In Growing Pigs, J A. Loughmiller, La Llata M. De, S Moser, R E. Musser, R D. Stott, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Thirty-five growing pigs (initially 65 ± 2 lb) were used in a metabolism study to determine the effects of a single enteric disease challenge on N retention, growth performance, and blood immunological variables. Twenty-one pigs were challenged with Salmonella typhimurium, and six pigs were assigned to an ad libitum-fed, nonchallenged control group. Eight additional nonchallenged pigs were pair-fed the feed intake of an S. typhimurium challenged counterpart. There were five 4 d collection periods (d 4 to 7, d 8 to 11, d 12 to 15, d 16 to 19, and d 22 to 25), with the S. typhimurium challenge ...


Evaluation Of A Porcine Coproduct (Pro-Blend 75®) From Slaughter Plants As A Protein Source For Starter Pig Diets, D J. Lee, B R. Dunsford, K L. Herkelman, J D. Hahn, Joe D. Hancock, Michael D. Tokach Jan 1998

Kansas Agricultural Experiment Station Research Reports

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


Sucrose And Molasses In Simple Or Complex Diets For Nursery Pigs, I Mavromlichalis, Robert H. Hines, B W. Senne, S P. Sorrell, H Cao, Joe D. Hancock, Joel M. Derouchey Jan 1998

Sucrose And Molasses In Simple Or Complex Diets For Nursery Pigs, I Mavromlichalis, Robert H. Hines, B W. Senne, S P. Sorrell, H Cao, Joe D. Hancock, Joel M. Derouchey

Kansas Agricultural Experiment Station Research Reports

Three experiments were conducted to determine the effects of replacing lactose with sucrose and molasses in simple and complex diets for nursery pigs. In general, complex diets supported greater growth performance than simple diets, and added lactose and sucrose gave greater efficiency of growth than diets without added sugars. Comparisons among sugar sources indicated that lactose, sucrose, and molasses were utilized equally well by weanling pigs.; Swine Day, Manhattan, KS, November 19, 1998


Added Dietary Fat Improves Growth Performance And Feed Efficiency In Growing-Finishing Pigs Under Commercial Conditions, S S. Drtiz, 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, S S. Drtiz, 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 ...


Expander Processing And Enzymes For A Wheat-Based Diet For Finishing Pigs, J S. Park, Robert H. Hines, G A. Kennedy, Joel M. Derouchey, D J. Lee, C A. Maloney, H Cao, Joe D. Hancock, Keith C. Behnke Jan 1998

Kansas Agricultural Experiment Station Research Reports

Overall ADG and ADFI were not affected, but feed efficiency was improved with pelleting and further improvements resulted from expander processing. In a second experiment, enzyme supplementation to mash, but not pelleted, diets improved feed efficiency. Indeed, F/G for pigs fed mash with enzyme was similar to that for pigs fed pelleted diets.; Swine Day, Manhattan, KS, November 19, 1998


Influence Of Chop Location On Boneless Pork Loin Quality, A T. Waylan, R C. Johnson, John A. Unruh Jan 1998

Influence Of Chop Location On Boneless Pork Loin Quality, A T. Waylan, R C. Johnson, John A. Unruh

Kansas Agricultural Experiment Station Research Reports

Eighty-two boneless pork loins were used to examine the effects of chop location on longissimus muscle quality. The highest quality chops came from the posterior end. They had the lowest Warner-Bratzler shear value (most tender), highest cooking yield, and a high pH and percent extractable lipid. Visual and instrumental data suggested that the most posterior chop was lighter colored and had the highest degree of marbling. Color, firmness, and marbling evaluations were similar in the central posterior section of the loin. This suggests that this section was very uniform in visual pork quality. The anterior portion of the loin was ...


Influence Of High Levels Of Zinc From Zinc Oxide, Zinc Sulfate, Or A Zinc Amino Acid Complex On Starter Pig Performance, J C. Woodworth, P R. O'Quinn, J A. Loughmiller, S A. Moser, T M. Fakler, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Steven S. Dritz Jan 1998

Influence Of High Levels Of Zinc From Zinc Oxide, Zinc Sulfate, Or A Zinc Amino Acid Complex On Starter Pig Performance, J C. Woodworth, P R. O'Quinn, J A. Loughmiller, S A. Moser, T M. Fakler, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Three hundred and sixty early-weaned barrows were fed either a control diet; diets containing added Zn (l00, 200, 300, 400, or 500 ppm) from zinc sulfate or a zinc amino acid complex (AvailaZn); or a diet containing 3,000 ppm of additional Zn from zinc oxide. All diets contained 165 ppm of Zn from zinc oxide from the trace mineral premix. Pigs fed 3,000 ppm of Zn from zinc oxide had maximum growth performance compared to those fed other diets, whereas those fed added zinc sulfate and AvailaZn showed intermediate results relative to the negative control and the 3 ...


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

Influence Of Spirulina Platensis On Growth Performance Of Weanling Pigs, 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


Effects Of Modified Tall Oil Versus Conjugated Linoleic Acid On Finishing Pig Growth Performance And Carcass Characteristics, P R. Oquinn, J W. Smith Ii, Michael D. Tokach, J Scott Smith, Jim L. Nelssen, Robert D. Goodband Jan 1998

Effects Of Modified Tall Oil Versus Conjugated Linoleic Acid On Finishing Pig Growth Performance And Carcass Characteristics, P R. Oquinn, J W. Smith Ii, Michael D. Tokach, J Scott Smith, Jim L. Nelssen, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

A growth trial was conducted to compare effects of modified tall oil (MTO) and conjugated linoleic acid (CLA) on growth performance, serum chemistry, and carcass composition of finishing barrows. Overall, pigs fed the control diet did not differ from pigs fed MTO or CLA supplemented diets. However, pigs fed MTO had greater ADG and ADFI than pigs fed CLA. No effect of treatment was observed for any of the measured carcass criteria or serum triglyceride levels. The results of this research do not suggest a benefit from feeding MTO or CLA to pigs but do indicate differences in ADG and ...


Effects Of Sorghum Endosperm Hardness And Processing On Growth Performance And Nutrient Digestibility In Pigs And Broiler Chicks, H Cao, Robert H. Hines, J S. Park, B W. Senne, J M. Jiang, J R. Froetschner, P Sorrell, Joe D. Hancock, Keith C. Behnke Jan 1998

Effects Of Sorghum Endosperm Hardness And Processing On Growth Performance And Nutrient Digestibility In Pigs And Broiler Chicks, H Cao, Robert H. Hines, J S. Park, B W. Senne, J M. Jiang, J R. Froetschner, P Sorrell, Joe D. Hancock, Keith C. Behnke

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


Enzyme Additions To Sorghum-Based Diets For Finishing Pigs, J S. Park, Robert H. Hines, C A. Maloney, H Cao, D J. Lee, Joe D. Hancock, Joel M. Derouchey Jan 1998

Enzyme Additions To Sorghum-Based Diets For Finishing Pigs, J S. Park, Robert H. Hines, C A. Maloney, H Cao, D J. Lee, Joe D. Hancock, Joel M. Derouchey

Kansas Agricultural Experiment Station Research Reports

Three experiments were conducted to determine the effects of a sorghum-specific enzyme supplementation on growth performance of finishing pigs. Although positive trends occurred, the sorghum-specific enzymes used in our experiments did not yield large and(or) consistent improvements in growth performance or nutrient digestibility in finishing pigs.; Swine Day, Manhattan, KS, November 19, 1998

Kansas Agricultural Experiment Station Research Reports

A total of 360 pigs (initially 11.5 lb and 16 d of age) was fed a negative control diet containing no added Zn; one of six diets containing 165 ppm Zn from zinc oxide from the trace mineral premix and added AvailaZn (0, 100,200, 300,400, or 500 ppm of Zn); or a positive control diet containing 3,165 ppm added Zn from zinc oxide. Pigs fed the positive control diet had higher (P<.02)ADG and ADFI compared to pigs in all other treatments for the duration of the trial. Pigs fed diets containing Availazn had numerically higher ADG and ADFI than pigs fed diets containing no added Zn for the entire trial. These results are similar to previous research showing maximum growth performance exhibited by pigs fed high levels (3,000 ppm) of Zn from zinc oxide.; Swine Day, Manhattan, KS, November 19, 1998


Effects Of Different Soybean Meal Processing Techniques On Growth Performance Of Pigs, J C. Woodworth, R E. Musser, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband Jan 1998

Effects Of Different Soybean Meal Processing Techniques On Growth Performance Of Pigs, J C. Woodworth, R E. Musser, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband

Kansas Agricultural Experiment Station Research Reports

A 35-d growth trial was conducted to determine the influence of different soybean meal processing techniques on starter pig growth performance. From d 0 to 14 after weaning, all pigs were fed a common diet. Then pigs were fed six experimental diets from d 14 to 35 after weaning. Three treatment comparisons were made. Pigs fed a diet containing extruded-expelled soybean meal (SBM) without hulls (Insta-Pro) were compared to those fed solvent-extracted SBM (46.50/0 CP) and 3.21% soy oil. Pigs fed a diet containing extruded-expelled SBM with hulls (lnsta-Pro) were compared to those fed a diet containing ...


Effects Of Particle Size And Mixing Time On Uniformity And Segregation In Pig Diets, N Amornthewaphat, Keith C. Behnke, Joe D. Hancock Jan 1998

Effects Of Particle Size And Mixing Time On Uniformity And Segregation In Pig Diets, N Amornthewaphat, Keith C. Behnke, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

Diet uniformity, as represented by the coefficient of variation (CV), improved as mixing time was increased from 15 to 120 seconds and(or) com particle size was decreased from 1,200 to 400 ~m. Segregation occurred during free-fall, and the coarser particle sizes resulted in greater segregation than the finer particle sizes. Thus, reducing particle size of the cereal grain in swine diets not only improves efficiency of growth (as demonstrated in numerous KSU Swine Day Reports) but also decreases mix time needed for adequate blending and the likelihood of segregation during handling, storage, and delivery of diets to feeders ...


Effects Of Diet Complexity And Processing Method On Growth Performance And Nutrient Digestibility In Nursery Pigs, S L. Traylor, Robert H. Hines, S L. Johnston, P Sorrell, Keith C. Behnke, Joe D. Hancock, Joel M. Derouchey Jan 1998

Effects Of Diet Complexity And Processing Method On Growth Performance And Nutrient Digestibility In Nursery Pigs, S L. Traylor, Robert H. Hines, S L. Johnston, P Sorrell, Keith C. Behnke, Joe D. Hancock, Joel M. Derouchey

Kansas Agricultural Experiment Station Research Reports

A complex diet formulation resulted in greater digestibility of nutrients and a trend for greater ADG for d 0 to 14 of the experiment. However, for d 14 to 28 and overall (d o to 28), diet complexity did not affect growth performance. In contrast, pelleting improved essentially every response criterion especially in simple diets. Expander conditioning before pelleting increased overall digestibility of nutrients and of F/G compared to standard conditioning, but again, the response was most pronounced with the simple diet formulations.; Swine Day, Manhattan, KS, November 19, 1998


Effects Of Enzyme Supplementation And Particle Size Of Wheat-Based Diets On Nursery And Finishing Pigs, I Mavromichalis, G A. Kennedy, Robert H. Hines, B W. Senne, S P. Sorrell, Joe D. Hancock, Joel M. Derouchey Jan 1998

Effects Of Enzyme Supplementation And Particle Size Of Wheat-Based Diets On Nursery And Finishing Pigs, I Mavromichalis, G A. Kennedy, Robert H. Hines, B W. Senne, S P. Sorrell, Joe D. Hancock, Joel M. Derouchey

Kansas Agricultural Experiment Station Research Reports

In nursery pigs, enzyme supplementation generally had no effect on ADG or F/G, but a trend occurred for greater digestibility of DM in pigs fed enzymes. However, one notable interaction occurred. Enzyme supplementation gave improved F/G at the coarser (l,300 mm) particle size but not at the finer (600 or 400 mm) particle sizes. In finishing pigs, trends for better F/G and digestibilities of DM and N with enzyme supplementation occurred in one experiment (1,300 vs 600 mm) but not in the other experiment (600 vs 400). Thus, the effects of enzyme supplementation were neither ...


Effects Of Poultry Fat And Choice White Grease On Pork Longissimus Muscle, Belly, And Bacon Quality, 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, 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, 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, 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


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, B W. Senne, Robert H. Hines, D W. Dean, I Mavromichalis, J R. Froetschner, Joe D. Hancock Jan 1998

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, 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


Effects Of Increasing Total Sulfur Amino Acid:Lysine Ratio On Growth Performance Of 25 To 50 Lb Pigs, M De La Llata, P R. O'Quinn, J C. Woodworth, S A. Moser, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz Jan 1998

Effects Of Increasing Total Sulfur Amino Acid:Lysine Ratio On Growth Performance Of 25 To 50 Lb Pigs, M De La Llata, P R. O'Quinn, J C. Woodworth, S A. Moser, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Three hundred and fifty pigs were used in a 27-d growth study to determine the appropriate total sulfur amino acid:lysine ratio for 25 to 50 lb pigs. Pigs were blocked by weight (initially 22.5 lb) and allotted to one of 10 treatments arranged in a 2 x 5 factorial with two levels of total dietary lysine (.95 and 1.250/0) and five total sulfur amino acid ratios (.45, .50, .55, .60, and .65% of total lysine). Increasing total lysine from .95 to 1.25% increased ADG and improved FIG. Increasing the total sulfur amino acid:lysine ratio ...


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

Phosphorus-Reducing Technologies In Swine Production, 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

Effects Of Increasing Pantothenic Acid On Growth Performance Of Segregated Early-Weaned Pigs, G S. Grinstead, R Stott, Robert D. Goodband, Jim L. Nelssen, Michael D. Tokach, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

We conducted a 28-d experiment to evaluate effects of increasing dietary pantothenic acid on growth performance of segregated early-weaned pigs. Pigs (initially 8.8 ± 2.21b and 11 ± 2 d of age) were fed a control diet (no added pantothenic acid) or the control diet with 30, 60, and 120 ppm of added pantothenic acid. Increasing pantothenic acid increased ADG and ADFI linearly from dO to 14 after weaning. However, from d 14 to 28 after weaning, pigs fed 60 mg/kg of added pantothenic acid tended to have the greatest ADG and ADFI. For the cumulative period ...

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 ...
