Effects Of Increasing Dietary Lysine On Performance Of Lactating Sows In Commercial Conditions, K. M. Gourley, J. C. Woodworth, J. M. Derouchey, M. D. Tokach, S. S. Dritz, R. D. Goodband, S. J. Kitt, E. W. Stephenson
Effects Of Increasing Dietary Lysine On Performance Of Lactating Sows In Commercial Conditions, K. M. Gourley, J. C. Woodworth, J. M. Derouchey, M. D. Tokach, S. S. Dritz, R. D. Goodband, S. J. Kitt, E. W. Stephenson
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, 1.05, and 1.20%). …
Effect Of Sow Lactation Crate Size On Litter Performance And Survivability, L. L. Thomas, K. F. Coble, C. W. Hastad, M. D. Tokach, S. S. Dritz, R. D. Goodband, J. M. Derouchey, J. C. Woodworth
Effect Of Sow Lactation Crate Size On Litter Performance And Survivability, L. L. Thomas, K. F. Coble, C. W. Hastad, M. D. Tokach, S. S. Dritz, R. D. Goodband, J. M. Derouchey, J. C. Woodworth
Kansas Agricultural Experiment Station Research Reports
A total of 529 litters of pigs (PIC TR4 × (Fast LW × PIC L02)) were used to examine the effect of sow lactation crate size on nursing pig litter performance and survivability. The sow portion of the farrowing crate was maintained at a constant length and width of 7.4 and 2.0 ft, respectively. To form the treatments, crate width was adjusted accordingly, taking space away from one sow’s crate to give it to another allowing for 3 crate widths: 4.8 (small), 5.4 (medium), and 6.0 ft (large). This allowed for blocks of 3 crates, where each treatment was represented. …
Validation Of Individual Computerized Sow Feeding Systems In Lactation, G. E. Nichols, K. M. Gourley, J. M. Derouchey, J. C. Woodworth, M. D. Tokach, S. S. Dritz, R. D. Goodband, H. L. Frobose
Validation Of Individual Computerized Sow Feeding Systems In Lactation, G. E. Nichols, K. M. Gourley, J. M. Derouchey, J. C. Woodworth, M. D. Tokach, S. S. Dritz, R. D. Goodband, H. L. Frobose
Kansas Agricultural Experiment Station Research Reports
Two experiments evaluated the accuracy of individual computerized feed delivery systems for lactating sows (GESTAL Solo, JYGA Technologies Inc., St-Lambert-de-Lauzon, Quebec, Canada). The feeders volumetrically dispense feed based on rotations of a screw auger. In Experiment 1, 29 prototype feeders were used across 3 farrowing groups. On d 0, 1 feeder was selected to calibrate the computer system to the bulk density of the lactation diet. Feeders were programmed for 5 feeding periods per day with feeding period allowing up to 4 feed drops triggered by the sow. Sows activate a trigger within the feed bowl to receive a targeted …
Effect Of Calsporin On Nursing Piglet Growth Performance And Fecal Microflora, M. B. Menegat, C. M. Vier, H. S. Cemin, D. Shawk, J. M. Derouchey, J. C. Woodworth, M. D. Tokach, S. S. Dritz, R. D. Goodband
Effect Of Calsporin On Nursing Piglet Growth Performance And Fecal Microflora, M. B. Menegat, C. M. Vier, H. S. Cemin, D. Shawk, J. M. Derouchey, J. C. Woodworth, M. D. Tokach, S. S. Dritz, R. D. Goodband
Kansas Agricultural Experiment Station Research Reports
A total of 26 lactating sows (DNA 241, DNA Genetics, Columbus, NE) and litters were used in a discovery study to evaluate the effects of Calsporin, a direct-fed microbial containingBacillus subtilisC-3102, on fecal microflora of nursing pigs. The treatments consisted of providing a daily oral dose of Calsporin or a placebo control to piglets during the nursing phase. Sows were randomly assigned to treatments based on farrowing date, parity, and initial BW. The treatments were applied individually to piglets once a day from d 2 after farrowing and equalization until weaning on d 19. Sow BW, sow ADFI, …
