Validation Of Flank-To-Flank Measurements For Predicting Boar Weight (2006), R C. Sulabo, J Quackenbush, Jim L. Nelssen, Robert D. Goodband, Michael D. Tokach, Joel M. Derouchey, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Allometric relationships, in which linear body dimensions are expressed as a function of body weight, are commonly used in growth studies. Previous work at Kansas State University showed a positive correlation between flank-to-flank measurement and sow body weight. Prediction equations were developed to estimate sow weight, but it is not known if the same equation will be valid in estimating body weight among other groups of pigs, such as boars. The objective of this study was to validate the use of flank-to-flank measurement in predicting boar weight, and to determine if the allometric equation for gestating sows can also be …

Effects Of Dried Distillers Grain With Solubles On Nursery Pig Performance (2006), S K. Linneen, M U. Steidinger, Michael D. Tokach, Joel M. Derouchey, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A total of 482 pigs (initial BW of 21.9 lb) were used in a 22-d study to determine the effects of dried distillers grains with solubles (DDGS) on growth performance of nursery pigs reared in a commercial environment. Pigs were allotted to one of two dietary treatments based on corn-soybean meal and containing either 0 or 10% DDGS. There was a tendency for pigs fed the diet containing 10% DDGS to have decreased (P<0.13) ADG, compared with pigs not fed DDGS (0.95 vs. 0.88 lb/d). Overall (d 0 to 22), there were no differences in ADFI, F/G, or final weight (P>0.21). For economic analysis, the DDGS price was compared at $109, $93, or $80/ton. There were no differences in feed cost per pound of gain in …

Effects Of Dried Distillers Grain With Solubles On Growing-Finishing Pig Performance (2006), S K. Linneen, R O. Gottlob, R G. Main, Michael D. Tokach, Joel M. Derouchey, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

Three experiments were conducted to determine the effects of increasing dried distiller's grains with solubles (DDGS) on growth performance and palatability in growing-finishing pigs. In Exp. 1, a total of 1,050 pigs (initially 104.9 lb) were used in a 28-d study in May 2002. Pigs were fed diets with either 0 or 15% DDGS and 0, 3, or 6% added fat, for a 2 × 3 factorial arrangement. Overall, there were no DDGS × fat content interactions (P = 0.20). There was an improvement (linear, P<0.01) in ADG and F/G with increasing added fat and no difference in growth performance between pigs fed 0 or 15% DDGS. In Exp. 2, a total of 1,038 pigs (initially 102.1 lb) were used in a 56-d study in August 2005. Pigs were fed diets with either 0, 10, 20, or 30% DDGS from the same ethanol plant as in Exp. 1. Overall (d 0 to 56), there was a trend for decreased ADG (linear, P<0.10) and ADFI (linear, P<0.06) as DDGS increased. The greatest reduction occurred in pigs fed more than 10% DDGS. In Exp. 3, a total of 120 growing pigs (initially 48.7 lb) were used in a 21-d feed preference study in October 2005. Pigs were randomly allotted to a pen with 4 feeders, each containing a separate dietary treatment. Pigs were offered diets based on corn-soybean meal, with 0, 10, 20, or 30% DDGS from the same source as in Exp. 1 and 2. For all periods (d 0 to 7, 7 to 21, and 0 to 21), there was a decrease in ADFI (quadratic, P<0.01) as DDGS increased in the diet. The most dramatic decrease was observed between 0 and 10% DDGS. Experiment 1 showed no difference in growth performance in pigs fed 0 or 15% DDGS. In Exp 2, at DDGS contents higher than 10%, there were trends for decreased ADG and ADFI; in Exp. 3, ADFI decreased with increasing DDGS in the diet. In summary, DDGS from the ethanol plant tested can be used at 10 to 15% in finishing diets without reducing pig performance. Higher percentages of DDGS in the diet decreased ADFI in growing and finishing pigs.; Swine Day, 2006, Kansas State University, Manhattan, KS, 2006

Comparison Of Particle Size Analysis Of Ground Grain With, Or Without, The Use Of A Flow Agent (2006), W Diederich, Robert D. Goodband, Michael D. Tokach, Joel M. Derouchey, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

The American Society of Biological and Agricultural Engineers' standard for particle size analysis indicates that the analysis can be conducted with or without the use of a flow agent. Because of this allowed variation in procedures, particle size analysis results can be variable and difficult to interpret, depending on whether the laboratory uses a flow agent or not. Therefore, a retrospective analysis was made of 603 samples of ground corn analyzed for particle size with, or without, 0.5 g of synthetic amorphous precipitated silica (SipernatÂ® 22-S) per 100 g of sample. Results of both analyses were compared with a Method …

Effects Of A Liquid (Neolac1) And Dry Feed Combination Fed In Varying Durations On Weanling Pig Performance, R C. Sulabo, C N. Groesbeck, J M. Benz, D Mckilligan, Robert D. Goodband, Michael D. Tokach, Joel M. Derouchey, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

One hundred eighty pigs (initially 11.4 lb and 18 days of age) were used in a 28-d growth assay to determine the effects on nursery pig performance of combining a complete liquid feed (Neolac) with dry feed for various durations. Pigs were randomly allotted to experimental treatments consisting of: dry feed only (control) or Neolac provided for a period of 3 and 7 days in combination with dry feed. Overall, pigs fed the liquid-dry feed combination had a greater ADG (P<0.01) than did the dry-fed pigs until d 7 after weaning. Weight gains obtained during this period were not maintained until the end of the nursery period, regardless of the duration of liquid feeding. Both dry matter intake (DMI) and DM feed/gain increased (P<0.01) as a result of liquid feeding. Pigs provided liquid feed for 7 d also had a higher DM feed/gain (P<0.06) than that of the dry-fed controls in all periods. Feeding a liquid complete diet for various durations, in combination with dry feed, only had positive effects on growth rate immediately after weaning, but did not have lasting gains to influence overall nursery performance. Further experiments are needed to determine whether the improvement in initial feed intake with liquid feeding will reduce "starve-outs" and mortality.; Swine Day, 2006, Kansas State University, Manhattan, KS, 2006
