Evaluation Of Medium Chain Fatty Acids As A Dietary Additive In Nursery Pig Diets, J. T. Gebhardt, K. A. Thomson, J. C. Woodworth, M. D. Tokach, J. M. Derouchey, R. D. Goodband, S. S. Dritz Jan 2017

Evaluation Of Medium Chain Fatty Acids As A Dietary Additive In Nursery Pig Diets, J. T. Gebhardt, K. A. Thomson, J. C. Woodworth, M. D. Tokach, J. M. Derouchey, R. D. Goodband, S. S. Dritz

Kansas Agricultural Experiment Station Research Reports

A total of 360 pigs [DNA (Columbus, NE) 400 × 200; initial BW = 14.8 lb] were used to evaluate the effects of dietary medium chain fatty acid (MCFA) addition on nursery pig performance. Upon arrival to the nursery, pigs were randomized to pens (5 pigs per pen) and allowed a 6-d acclimation period, at which point pens of pigs were blocked by BW and randomized to dietary treatment (9 pens per treatment). Medium chain fatty acids (Sigma Aldrich, St. Louis, MO) included hexanoic (C6), octanoic (C8), and decanoic (C10), and were guaranteed ≥ 98% purity. Treatment diets were formulated and manufactured ...


Effects Of Dietary Ca And P Concentrations On Growth Performance Of 13- To 25-Lb Pigs, F. Wu, M. D. Tokach, J. M. Derouchey, S. S. Dritz, J. C. Woodworth, R. D. Goodband Jan 2017

Effects Of Dietary Ca And P Concentrations On Growth Performance Of 13- To 25-Lb Pigs, F. Wu, M. D. Tokach, J. M. Derouchey, S. S. Dritz, J. C. Woodworth, R. D. Goodband

Kansas Agricultural Experiment Station Research Reports

A total of 360 nursery pigs (PIC 1050 × 280, initially 13.3 ± 2.39 lb) were used in a 45-d growth study to determine the effects of feeding 2 standardized total tract digestible (STTD) P and 3 Ca concentrations on growth performance. In a completely randomized design, pens of pigs (10 pigs per pen, 6 pens per treatment) were allotted randomly to 1 of 6 dietary treatments. Dietary treatments were arranged in a 2 × 3 factorial, with 2 levels of STTD P (at or above NRC requirement estimates) and 3 levels of Ca (0.65, 0.90, and 1.20 ...


Standardized Total Tract Digestible Phosphorus Requirement Of 25- To 50-Lb Pigs, C. M. Vier, F. Wu, S. S. Dritz, M. D. Tokach, M. A. Goncalves, U. A. Orlando, J. C. Woodworth, R. D. Goodband, J. M. Derouchey Jan 2017

Standardized Total Tract Digestible Phosphorus Requirement Of 25- To 50-Lb Pigs, C. M. Vier, F. Wu, S. S. Dritz, M. D. Tokach, M. A. Goncalves, U. A. Orlando, J. C. Woodworth, R. D. Goodband, J. M. Derouchey

Kansas Agricultural Experiment Station Research Reports

A total of 1,080 barrows and gilts (PIC; 337 × Camborough, initial pen average BW of 25.2 ± 0.64 lb) were used in a 21-d trial to determine the standardized total tract digestible (STTD) P requirement of nursery pigs from 25 to 50 lb. Two groups of pigs were weaned at approximately 21 d and allotted to pens according to BW and gender. There were 6 replicate pens per treatment and 23 to 27 pigs per pen. Pens of pigs were randomly allotted to experimental diets based on average BW at d 21 and 24 post-weaning, in a randomized ...


Effects Of Dietary Calcium And Phosphorus Concentrations And Addition Of Phytase On Growth Performance Of Nursery Pigs, F. Wu, M. D. Tokach, J. M. Derouchey, S. S. Dritz, J. C. Woodworth, R. D. Goodband Jan 2017

Effects Of Dietary Calcium And Phosphorus Concentrations And Addition Of Phytase On Growth Performance Of Nursery Pigs, F. Wu, M. D. Tokach, J. M. Derouchey, S. S. Dritz, J. C. Woodworth, R. D. Goodband

Kansas Agricultural Experiment Station Research Reports

A total of 720 nursery pigs (PIC 1050 × 280, initially 13.4 ± 0.47 lb) were used in a 42-d growth study to determine the effects of feeding 2 calcium (Ca) and 3 standardized total tract digestible (STTD) phosphorus (P) concentrations on growth performance and bone ash content. Pens of pigs (10 pigs/pen, 12 pens/treatment) were blocked by initial pen weight, and within blocks pens were allotted randomly to 1 of 6 dietary treatments. Dietary treatments were arranged in a 2 × 3 factorial, with 2 levels of Ca (0.58 vs. 1.03%) and 3 levels of STTD ...
