This study aimed to evaluate the effects of daily phase feeding (DP) and sequential (SEQ) on behavior, performance, body composition growing-finishing pigs. Sixty barrows at 29.7 ± 2.8 kg weight (BW) were assigned one four treatments: DP with a blended proportion feeds A (high nutrient density) B (low was adjusted match 100 % amino acid (AA) diet recommendations (DP100); negative treatment, whi...

Increased corn prices over the past decade have altered land use away from traditional forage in favor of corn. Accordingly, beef and dairy producers have had to adopt nontraditional forage resources into their production systems, many of which have become available as a result of increased corn production. Corn residues have become more available due to increases in corn hectares and yield. Th...

Previous reviews have covered our work on the efficacy of a new E. coli-derived phytase (expressed in yeast) for releasing phytate-bound phosphorus (P) present in corn-soybean meal diets for young pigs, growing-finishing pigs, broiler chicks and laying hens (Baker and Augspurger, 2002; Augspurger, 2003; Augspurger et al., 2003a). It is not our intent to repeat this information, but instead to p...

Ammonium polyphosphate (APP) was substituted for 0, 50 and 100% of the P supplied by defluorinated rock phosphate (DRP) in corn-soybean meal diets for growing rats and growing-finishing (G-F) pigs. The diets were formulated to contain 10% protein, .75% Ca and .60% P. Two-thirds of the P in the control diet was supplied by DRP. Replacement of 50 or 100% of the DRP with APP increased the dietary ...

and Implications Because treatment with calcium oxide (CaO) will increase the digestibility of corn stover, CaO-treated corn stover may be a cost-effective alternative to a portion of corn grain in beef feedlot diets. Single-pass harvested corn stover was ensiled either untreated or treated with 5% CaO on a dry matter (DM) basis. Ground baled stover, untreated stover silage, or CaO-treated stov...

Five experiments (five different locations) with a total of 1,230 pigs (135 pens) were conducted in Minnesota, Missouri and Indiana to study the effects of supplementary bambermycins (2.2 ppm) and tylosin (44 or 22 ppm) in swine diets. The antibiotics were fed during the growing and finishing periods, and effects on rate of gain and efficiency of feed conversion were measured. A significant imp...
