dc.description.abstract | Two experiments were conducted to test the effects of wheat source and particle size in meal and pelleted diets on finishing pig performance, carcass characteristics, and diet digestibility. In Exp. 1, pigs (PIC 327 × 1050; n = 288; initially 43.8 kg BW) were balanced by initial BW and randomly allotted to 1 of 3 treatments with 8 pigs per pen (4 barrows and 4 gilts) and 12 pens per treatment. The 3 dietary treatments were hard red winter wheat ground with a hammer mill to 728, 579, or 326 ?m, respectively. From d 0 to 40, decreasing wheat particle size decreased (linear, P < 0.033) ADFI but improved (quadratic, P < 0.014) G:F. From d 40 to 83, decreasing wheat particle size increased (quadratic, P < 0.018) ADG and improved (linear, P < 0.002) G:F. Overall from d 0 to 83, reducing wheat particle size improved (linear, P < 0.002) G:F. In Exp. 2, pigs (PIC 327 × 1050; n = 576; initially 43.4 ± 0.02 kg BW) were used to determine the effects of wheat source and particle size of pelleted diets on finishing pig growth performance and carcass characteristics. Pigs were randomly allotted to pens, and pens of pigs were balanced by initial BW and randomly allotted to 1 of 6 dietary treatments with 12 replications per treatment and 8 pigs/pen. The experimental diets used the same wheat–soybean meal formulation, with the 6 treatments using hard red winter or soft white winter wheat that were processed to 245, 465, and 693 ?m and 258, 402, and 710 ?m, respectively. All diets were pelleted. Overall, feeding hard red winter wheat increased (P < 0.05) ADG and ADFI when compared with soft white winter wheat. There was a tendency (P < 0.10) for a quadratic particle size × wheat source interaction for ADG, ADFI, and both DM and GE digestibility, as they were decreased for pigs fed 465-?m hard red winter wheat and were greatest for pigs fed 402-?m soft white winter wheat. There were no main or interactive effects of particle size or wheat source on carcass characteristics. In summary, fine grinding hard red winter wheat fed in meal form improved G:F and nutrient digestibility, whereas reducing particle size of wheat from approximately 700 to 250 ?m in pelleted diets did not influence growth or carcass traits. Finally, feeding hard red winter wheat improved ADG and ADFI compared with feeding soft white winter wheat. © 2016 American Society of Animal Science. All rights reserved. | |
