A total of 1,134 barrows and gilts (PIC; 359 × Camborough) with an initial pen average body weight (BW) of 58.0 ± 1.57 lb were used in a 110-d growth trial to determine the effects of feeding different analyzed total calcium to phosphorus (Ca:P) ratios on performance of growing-finishing pigs from 58 to 281 lb. Pens of pigs were randomly assigned to 1 of 6 dietary treatments in a randomized complete block design with BW as a blocking factor. There were 7 replicate pens per treatment and 27 pigs per pen. The experimental diets were corn-soybean meal-based, and were fed …

The objective of this experiment was to determine the effects of mill type used to grind corn and its particle size variation on diet flowability and subsequent finishing pig growth performance and carcass characteristics. A total of 200 pigs (DNA Line 241 × 600; initially 121.9 lb) were used in a 75-d growth trial. Pigs were randomly assigned to pens with either 5 barrows or 5 gilts per pen. Pens were then randomly allotted to 1 of 4 treatments balanced by weight and gender with 10 pens per treatment. Treatments were arranged as a 2 × 2 factorial with 2 …

Kansas Agricultural Experiment Station Research Reports
A total of 287 pigs (DNA 600 × 241; initially 111.8 lb) were used in an 86-d experiment to determine the effect of dietary fiber source on finishing pig growth performance and carcass characteristics. There were 12 pens per treatment with 7 or 8 pigs per pen. Pens were randomly assigned to 1 of 3 dietary treatments consisting of a control (8.7% neutral detergent fiber; NDF), 20% dried distillers grains with solubles (DDGS; 13.6% NDF), or 14.5% sugar beet pulp (SBP; 13.6% NDF). Experimental diets were fed from d 0 to 86 in 3 phases; d 0 to 18, d …
