Effects Of Increasing Ca:P Ratio In Diets Containing Phytase On Finishing Pig Growth Performance, S M. Hanni, M R. Barker, N Z. Frantz, C N. Groesbeck, T P. Keegan, C W. Hastad, Michael D. Tokach, Jim L. Nelssen, Joel M. Derouchey, Robert D. Goodband, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A total of 144 finishing pigs (72 barrows and 72 gilts, initially 85 lb) were used to determine the effects of calcium to total phosphorus (Ca:P) ratio in diets containing phytase on growth performance, carcass characteristics, and bone ash percentage. Pigs were housed in an environmentally regulated finishing building with two pigs per pen and six pens per sex per treatment in a randomized complete block design. Pigs were blocked by initial weight and sex, and then allotted to one of six dietary treatments. The dietary treatments were corn-soybean meal-based diets fed in three phases. In each phase, diets ...


Effect Of Added Fat On Performance Of Growing-Finishing Pigs In Commercial Conditions, M G. Young, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz Jan 2003

Effect Of Added Fat On Performance Of Growing-Finishing Pigs In Commercial Conditions, M G. Young, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A total of 1,040 pigs (half barrows and half gilts) was used in a 42-day experiment conducted in a commercial research facility to determine the influence of graded levels of added fat on growth performance, feed cost per pound of gain and margin over feed of growing-finishing pigs. The four dietary treatments were based on level of added dietary fat (0, 2, 4, or 6%), with the diets fed for a six-week period from 158 to 232 lb. Adding fat to the diet for pigs weighing 158 to 232 lb decreased ADFI, improved feed efficiency, increased cost per pound ...


Corn Particle Size And Pelleting Influence On Growth Performance, Fecal Shedding, And Lymph Node Infection Rates Of Salmonella Enterica Serovar Typhimurium, M R. Barker, J Ernest Minton, Joel M. Derouchey, K M. Bond, D J. Lee, T E. Burkey, Steven S. Dritz Jan 2003

Corn Particle Size And Pelleting Influence On Growth Performance, Fecal Shedding, And Lymph Node Infection Rates Of Salmonella Enterica Serovar Typhimurium, M R. Barker, J Ernest Minton, Joel M. Derouchey, K M. Bond, D J. Lee, T E. Burkey, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Ninety-six pigs (initially 13.8 lb.) were used in a 28-d trial to determine the interactive effects between pelleting and particle size on Salmonella serovar Typhimurium shedding and colonization in a young growing pig model. The experiment was a 2 × 2 factorial arrangement consisting of meal or pelleted diets with fine or coarse ground corn. Pigs were fed the diets 1 wk pre-salmonella inoculation and allotted based on weight to one of four dietary treatments. For the main effect of particle size, pigs fed finer ground corn had significantly improved feed efficiency (P<0.01) than pigs fed coarser ground corn for the 28 d trial. Pigs fed meal diets had greater ADG, ADFI, and improved F/G (P<0.05) than the pigs fed pelleted diets. Fecal shedding of salmonella was low and variable, with no significant differences between main effects (P<0.26) or in treatments (P>0.82). There was no difference ...


Comparision Of Antimicrobial Alternatives In Irradiated Diets For Nursery Pigs, T P. Keegan, C W. Hasted, Joel M. Derouchey, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband, Steven S. Dritz Jan 2003

Comparision Of Antimicrobial Alternatives In Irradiated Diets For Nursery Pigs, T P. Keegan, C W. Hasted, Joel M. Derouchey, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Previous research at Kansas State University indicated that irradiation can effectively reduce the bacteria concentration in nursery diets. Therefore, we hypothesized that eliminating bacteria in the feed via irradiation would provide a model to determine the effectiveness of antimicrobial alternatives. In a 27-d growth assay, 330 weanling pigs (13.2 lb and 18 ± 2 d of age, PIC) were fed one of 9 experimental diets: 1) control diet with no antimicrobials, 2) irradiated control diet with no antimicrobials, and the irradiated control diet with added: 3) carbadox (50 g/ton), 4) Probios® (1.6% from d 0 to 14 ...


Use Of Dried Distiller’S Grains With Soluble For Swine Diets, C W. Hastad, C N. Groesbeck, K R. Lawrence, N A. Lenehan, T P. Keegan, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Joel M. Derouchey, Steven S. Dritz Jan 2003

Use Of Dried Distiller’S Grains With Soluble For Swine Diets, C W. Hastad, C N. Groesbeck, K R. Lawrence, N A. Lenehan, T P. Keegan, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Joel M. Derouchey, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A large increase in the number of ethanol plants has lead to increased availability of dried distiller’s grains with solubles (DDGS). New plants also have improved processing techniques, which makes DDGS more attractive to use in swine diets. Two experiments were conducted to determine the energy value of DDGS. In Experiment 1, 360 pigs (each initially 38.5 lb) were used in a 22 d growth assay. Treatments consisted of five corn-soybean meal-based diets with added wheat bran or soy oil to provide five different energy densities ranging from 1,390 to 1,604 Kcal/lb ME. The objective ...


Pelleted Diets For Lactating Sows, E C. Baudon, Joe D. Hancock Jan 2003

Pelleted Diets For Lactating Sows, E C. Baudon, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

A total of 76 sows (parities one to four) were used to determine the effects of pelleted diets on sow and litter performance. In the 21-d lactation experiment, the sows were given a corn-soybean meal-based diet in meal (corn ground to a particle size of 500 to 600 μm) or a pelleted (3/16 inch pellet diameter) form. Diet form did not affect ADFI or lactation BW loss (P=0.15 or greater). Also, pigs weaned per litter, piglet survivability, litter weight gain, and days to estrus were not affected by treatment (P=0.15 or greater). However, sows fed ...


Effects Of A Heat-Stable Yeast Product And Antibiotics In Diets For Nursery Pigs, C L. Jones, C W. Starkey, Joe D. Hancock Jan 2003

Effects Of A Heat-Stable Yeast Product And Antibiotics In Diets For Nursery Pigs, C L. Jones, C W. Starkey, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

A total of 192 pigs (average initial BW of 15 lb and 21 d of age) were used in a 35-d experiment to determine the effects of a heatstable yeast product on growth performance of nursery pigs fed diets without and with antibiotics. Treatment diets were formulated to: 1.7% lysine for d 0 to 7, 1.5% lysine for d 7 to 21, and 1.3% lysine for d 21 to 35. The treatments were arranged as a 2 × 2 factorial, with main effects of antibiotics (without and with carbadox at 50 g/ton) and yeast (without and ...

Effects Of Diet Complexity And Replacement Of Soybean Meal On Growth Performance Of Weanling Pigs, E C. Baudon, N Llanes, Joe D. Hancock

Kansas Agricultural Experiment Station Research Reports

A total of 192 pigs (avg initial BW of 13.9 lb and avg initial age of 21 d) was used to determine the effects of complex diet formulations (with plasma protein and whey) in nursery diets with wheat gluten used to replace soybean meal. Treatments were arranged as a 2 x 2 factorial, with main effects of diet complexity (no animal plasma and 10% dried whey vs 7% animal plasma and 20% dried whey) and soybean meal (25% vs none). For d 0 to 14, the complex diet formulations increased ADG while replacement of the soybean meal with wheat ...
