A total of 1,201 finishing pigs (initially 63 lb) were used in a 99-d growth trial to evaluate the effects of increasing stocking density on finishing pig growth performance. Single-sex pens of barrows and gilts were blocked to minimize variation due to gender and barn location. There were 12 pens...

The economic impact of removing the heaviest pigs (topping) before marketing a finishing group and the effect of topping on performance of the remaining pigs were determined in 2 studies. In Exp. 1, a total of 1,126 pigs (BW=241 lb; 25 pigs/pen) were randomly assigned to 1 of 3 treatments: topping...

A total of 336 finishing gilts (initially 258 lb) were used in a 21-d growth trial to evaluate the effects of increasing stocking density on performance of pigs classified in the slower-growing fraction of the pig population. Pens of gilts were blocked to minimize variation associated with barn...

An experiment was conducted to evaluate the effects of weaning time (PM or AM) on nursery-pig growth performance. The objective was to see how weanling pigs would adjust to the nursery environment if sows were removed from the farrowing crates 12 h before moving pigs into the nursery. Each sow and...

A total of 512 commercial finishing pigs were used in a 15-d trial to determine the effects of mixing late-finishing pigs from 1 or 2 barns at different stocking densities on pig performance prior to marketing. Close-to-market-weight pigs from 2 barns (north barn or south barn) were placed in 32...

In Exp. 1, 96 sows (PIC C29) and their litters were used to determine the effects of creep diet complexity on preweaning performance and the proportion of piglets consuming creep feed. The experimental treatments were: (1) no creep feed (n=26), (2) simple creep diet (n=26), and (3) complex creep...

Objective: To evaluate the effects on nursery pig growth performance when sows are withdrawn either the afternoon before their pigs move to the nursery or the morning when the pigs move to the nursery. Materials and methods: A total of 542 weanling pigs (PIC L327 × L42) from 50 litters were used in ...

A total of 1,143 pigs (PIC 337×1050, initially 55.3 lb) were used to determine the effects of tribasic copper chloride (TBCC; Intellibond C; Micronutrients Inc., Indianapolis, IN) or copper sulfate (CuSO₄) on growth performance, carcass characteristics, pen cleanliness, and economics in a 111-d...

A total of 208 sows and 288 gilts (PIC line C29) were used to determine the influence of feeding frequency (2 vs. 6 times/d, floor fed) on performance and welfare measurements on a commercial sow farm. Treatments consisted of feeding similar amounts of feed to each sow (2.5 kg) or gilt (2.05 kg)...

A total of 208 sows and 288 gilts (PIC Line C29) were used to determine the influence of feeding frequency (2 versus 6 times per day) in gestation on performance and welfare measurements. The experiment was conducted on a commercial sow farm in northeast Kansas that typically housed gestating sows...
