Kansas Agricultural Experiment Station Research Reports

A 14-d growth trial was conducted to evaluate effects of increasing isoleucine: lysine ratios on growth performance of the segregated early-weaned pig. Twelve experimental diets included two levels of lysine (1.15%and 1.50% digestible lysine) and six digestible isoleucine: lysine ratios (40, 45,50, 55, 60, and 65% relative to lysine) in a 2 x 6 factorial arrangement. From d 0 to 14, growth performance was improved by feeding 1.50% digestible lysine. A linear improven1ent in growth performance occurred from d 0 to 7 as the isoleucine:lysine ratio increased. Although a significant quadratic response was not observed, little improvement in pig performance …

Effects Of Spray-Dried Blood Cells In Lactation Diets On Sow And Litter Performance (1996), E Weaver, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Steven S. Dritz Jan 1996

Effects Of Spray-Dried Blood Cells In Lactation Diets On Sow And Litter Performance (1996), E Weaver, Michael D. Tokach, Jim L. Nelssen, Robert D. Goodband, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

High producing sows were used to evaluate the effect of spray-dried blood cells as a dietary protein source on lactation performance and subsequent reproductive performance. No significant differences were observed between sows fed a corn-soybean cells-based diet or a diet containing 2.5% spray-dried blood cells for lactation performance or subsequent reproductive performance. Therefore, spray-dried blood cells can be used as a partial replacelnent for the protein source in lactation diets.; Swine Day, Manhattan, KS, November 21, 1996

Effects Of Select Menhaden Fish Meal Fed During Lactation On Sow And Litter Performance (1996), R E. Musser, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen, Steven S. Dritz Jan 1996

Effects Of Select Menhaden Fish Meal Fed During Lactation On Sow And Litter Performance (1996), R E. Musser, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A total of 317 lactating sows was fed either a corn-soybean meal diet (l.0%lysine) or a diet with a portion of the soybean meal replaced with 5% select menhaden fish meal on an equal lysine basis. Adding 5% select menhaden fish meal had no overall effect on sow or litter performance. Composition of milk samples collected between d 14 and 16 of lactation was not affected by dietary treatment.; Swine Day, Manhattan, KS, November 21, 1996

Increasing Valine, Isoleucine, And Total Branched Chain Amino Acids For The Lactating Sow (1996), B T. Richert, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen Jan 1996

Increasing Valine, Isoleucine, And Total Branched Chain Amino Acids For The Lactating Sow (1996), B T. Richert, Robert D. Goodband, Michael D. Tokach, Jim L. Nelssen

Kansas Agricultural Experiment Station Research Reports

One hundred eighty-five sows were used to evaluate effects of the interrelationship between isoleucine and valine on sow and litter performance. Litter weight and weight gain at weaning increased as dietary valine, isoleucine, and total branched chain amino acids increased. Increasing dietary valine increased concentrations of milk DM and fat. Milk DM, CP, and fat increased as dietary isoleucine increased. Both valine and isoleucine increased litter weights. The independent increases in litter weaning weights from adding valine and isoleucine suggest separate modes of action in the lactating sow.; Swine Day, Manhattan, KS, November 21, 1996

An Evaluation Of Several Diet Acidifiers Commonly Utilized In Pig Starter Diets To Improve Growth Performance (1996), J R. Bergstrom, J A. Loughmiller, R E. Musser, W B. Nessmith Jr, Jim L. Nelssen, Michael D. Tokach, Robert D. Goodband Jan 1996

Early-weaned pigs (weaned at 14 d of age) that are managed in a conventional one-site production system and fed a complex segregated early-weaning diet will benefit from the inclusion of a diet acidifier during the first week. However, the data indicate no benefit from including a diet acidifier in semicomplex diets fed during subsequent growth phases.; Swine Day, Manhattan, KS, November 21, 1996

The Effects Of Porcine Reproductive And Respiratory Syndrome (Prrs) Vaccination On Postweaning Growth Performance (1996), S D. Pretzer, K M. Claussen, J R. Bergstrom, Steven C. Henry, R Phillips, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz Jan 1996

We evaluated the effects of a modified-live virus vaccine for PRRS virus on nursery growth performance. The pigs used in this study were obtained from a herd with substandard nursery growth performance attributed to PRRS virus infection. We failed to detect the presence of active circulating field strain virus in either the controls or vaccinated pigs. However, we did detect a strain similar to the vaccine virus strain on d 34 after weaning in the vaccinated pigs. The vaccinated pigs had poorer growth performance from d 7 to 14 after vaccination and were lighter in weight for the remainder of …

Dietary Methionine Requirement For Optimal Growth Performance And Carcass Characteristics In Finishing Gilts (1996), J A. Loughmiller, Michael D. Tokach, Evan C. Titgemeyer, J R. Bergstrom, I H. Kim, J W. Smith Ii, W B. Nessmith, Jim L. Nelssen, Robert D. Goodband Jan 1996

In Exp. 1, increasing dietary methionine from .12 to .22% (.10 to .20% apparent digestible methionine) in diets containing excess cystine had no effect on ADG, ADFI, 10th rib fat depth, and longissimus muscle area in finishing gilts from 130 to 190 lb. However, increasing dietary methionine tended to linearly improve feed efficiency. In Exp. 2, increasing dietary methionine from .11 to . 17% (. 10 to . 15% apparent digestible methionine) in diets containing excess cystine resulted in linear improvements in ADG, ADFI, and F/G in finishing gilts from 160 to 230 lb. Quadratic improvements were observed for F/G. …
