Kansas Agricultural Experiment Station Research Reports

Two experiments were conducted to determine the effects of mix time on diet uniformity and growth performance of nursery and finishing pigs. For Exp. 1, 120 weanling pigs (average initial body wt of 12.1 lb) were used in a 27-d growth assay. The same Phase I diet (pelleted) was fed to all pigs for 7 d postweaning, then the pigs were switched to Phase II diet treatments for d 7 to 27. Treatments were mixing times of 0, .5, 2, and 4 min per 1,000 lb batch of complete feed in a double-ribbon mixer. From d 7 to 27, ADG …

Kansas Agricultural Experiment Station Research Reports

A total of three hundred pigs (initial BW = 111.6 lb) was used in two identical 70-d growth trials to determine the effect of feeder design on finishing pig growth performance. Pigs were allotted by initial body weight and were assigned to pens with one of three different feeder designs. Five replications of each treatment were evaluated during the summer (July through September) and another five replications during winter months (November through January). All pigs were fed the same milo-soybean meal diet formulated to contain .65% lysine, .65% Ca, and .55% P and fed in meal form. Feeder design had …
