Effects Of Lysine On Performance Of Lactating Primiparous Sows, K. M. Gourley, J. C. Woodworth, J. M. Derouchey, M. D. Tokach, S. S. Dritz, R. D. Goodband Jan 2016

Effects Of Lysine On Performance Of Lactating Primiparous Sows, K. M. Gourley, J. C. Woodworth, J. M. Derouchey, M. D. Tokach, S. S. Dritz, R. D. Goodband

Kansas Agricultural Experiment Station Research Reports

A total of 111 primiparous sows (Line 241; DNA, Columbus, NE) were used in a 21-d study to determine the effect of lysine (Lys) intake during lactation on sow and litter performance and subsequent reproductive performance of primiparous sows. At d 110 of gestation, sows were weighed and randomly assigned to treatment based on weight block. Dietary treatments consisted of increasing levels of standardized ileal digestible (SID) Lys (0.80, 0.95, 1.10, and 1.25% with other AA meeting or exceeding NRC [2012] recommendations as a ratio to Lys). All other nutrients met or exceeded the NRC (2012 ...


Ruminally-Protected Lysine (Safegain) Improves Performance Of Growing Beef Cattle, V. A. Veloso, C. L. Van Bibber-Krueger, J. S. Drouillard Jan 2016

Ruminally-Protected Lysine (Safegain) Improves Performance Of Growing Beef Cattle, V. A. Veloso, C. L. Van Bibber-Krueger, J. S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Lysine frequently is cited as the first-limiting amino acid for cattle diets. Synthetic lysine, while routinely added to pig diets, is ineffective in fulfilling lysine requirements of cattle due to extensive degradation by microbes within the rumen. Lysine can be encapsulated with compounds, such as saturated fats, that minimize degradation by ruminal microbes, thereby assuring that a greater proportion of the amino acid is available for absorption post-ruminally. The purpose of this experiment was to measure the impact of SafeGain (H.J. Baker & Bro. Inc., Little Rock, AR), an encapsulated form of lysine sulfate, on rate of gain and feed ...


Diet Formulation Method Influences The Response To Increasing Net Energy For Growing-Finishing Pigs, D. Marcal, M. D. Tokach, S. S. Dritz, J. C. Woodworth, R. D. Goodband, J. M. Derouchey Jan 2016

Diet Formulation Method Influences The Response To Increasing Net Energy For Growing-Finishing Pigs, D. Marcal, M. D. Tokach, S. S. Dritz, J. C. Woodworth, R. D. Goodband, J. M. Derouchey

Kansas Agricultural Experiment Station Research Reports

The objective of this study was to compare the effects of increasing dietary net energy (NE) in growing-finishing diets with maintaining a standardized ileal digestible (SID) Lys:NE ratio or not adjusting this ratio and keeping SID Lysine (Lys) constant across increasing NE density. A total of 150 pigs (Line 600 Duroc × Line 241, DNA, Columbus, NE) were used in a 91-d trial. Pens of pigs were blocked by gender and BW before being randomly assigned to treatments with 2 pigs per pen and 15 pens per treatment. Treatment diets included a low-energy negative control diet and a 2 × 2 ...


Effects Of Increasing Dietary Standardized Ileal Digestible Lysine On 15 To 24 Lb Nursery Pigs, A. B. Clark, M. D. Tokach, J. M. Derouchey, S. S. Dritz, R. D. Goodband, J. C. Woodworth, K. Touchette Jan 2016

Effects Of Increasing Dietary Standardized Ileal Digestible Lysine On 15 To 24 Lb Nursery Pigs, A. B. Clark, M. D. Tokach, J. M. Derouchey, S. S. Dritz, R. D. Goodband, J. C. Woodworth, K. Touchette

Kansas Agricultural Experiment Station Research Reports

A total of 300 nursery pigs (PIC 327 × 1050, initially 14.8 lb BW) were used in a 28-d growth trial to evaluate the effects of increasing dietary standardized ileal digestible (SID) lysine (Lys) on nursery pig growth performance. Pigs were weaned at approximately 21 d of age and allotted to the pens according to BW and gender. A common starter diet was fed for 6 d, then pens were allotted to 1 of 6 dietary treatments in a completely randomized design. Experimental diets were fed for 14 d followed by a common diet for 14 d. The 6 dietary ...
