Kansas Agricultural Experiment Station Research Reports

A total of 710 mixed parity sows (Line 241; DNA, Columbus, NE) were used in a 21-d study to determine the effect of standardized ileal digestible (SID) lysine (Lys) intake during lactation on sow and litter performance and subsequent reproductive performance of primiparous and multiparous sows housed in a commercial production system. On d 112 of gestation, females were weighed and blocked by BW within expected farrowing date and parity (1 to 7) and randomly assigned to 1 of 4 dietary treatments within blocks. Dietary treatments were corn-soybean meal-based and consisted of increasing SID Lys (0.75, 0.90, 1 ...


Effects Of Standardized Ileal Digestible Lysine On 15- To 25-Lb Nursery Pigs, G. E. Nichols, C. M. Vier, A. B. Clark, M. B. Menegat, H. S. Cemin, C. K. Jones, J. M. Derouchey, M. D. Tokach, R. D. Goodband, J. C. Woodworth, S. S. Dritz Jan 2017

Kansas Agricultural Experiment Station Research Reports

A total of 300 pigs (DNA 241 × 600; initial pen average BW of 15.4 lb) were used in a 22-d growth trial to determine the standardized ileal digestible (SID) lysine (Lys) requirement of nursery pigs from 15- to 25-lb. Pigs were weaned at approximately 21 d of age and allotted to pens based on BW and gender. There were 10 replicate pens per treatment and 6 pigs per pen. Pigs were fed a common pelleted diet for 10 d post-weaning. Subsequently, pens of pigs were randomly assigned to 1 of 6 experimental diets in a randomized complete block design ...


Effects Of Amino Acid Ratios And Lysine Level On Nursery Pig Growth Performance, A. B. Clark, M. D. Tokach, J. M. Derouchey, S. S. Dritz, J. C. Woodworth, R. D. Goodband, K. J. Touchette Jan 2017

Kansas Agricultural Experiment Station Research Reports

A total of 2,268 pigs (PIC 327 × L42, initially 16.2 lb BW) was used in a 28-d growth study with 54 pigs per feeder (experimental unit) and 6 replications per treatment. Pigs were randomly allotted to pens at weaning and fed a common starter diet for 8 d. Pens were then blocked by BW and allotted to 1 of 7 dietary treatments in a randomized complete block design. Treatments were arranged in two levels of standardized ileal digestible (SID) Lys (low,1.25% and high, 1.35%) and SID amino acid (AA) ratios relative to Lys (industry, 95 ...
