A total of 757 pigs (PIC 337 × 1050, initially 60.8 lb) were used to determine the effects of added Cu (TBCC, tribasic copper chloride, IntelliBond C; Micronutrients, Inc., Indianapolis, IN) and diet type on growth performance, carcass characteristics, energy digestibility, gut morphology, and mucosal mRNA expression of finishing pigs. Pens of pigs were allotted to 1 of 4 dietary treatments, balanced on average pen weight in a randomized complete-block design with 26 to 28 pigs per pen and 7 replications per treatment. Treatments were arranged as a 2 × 2 factorial with main effects of diet type, a corn-soybean meal-based ...

The following information is related to the use of a spreadsheet tool designed to estimate the growth rate of finishing pigs provided varying floor space allowances. The spreadsheet is broken into four sections: 1) the adjustment observation section, 2) the estimate input section, 3) the database range information, and 4) the predicted performance output. Sections 1 and 2 allow users to input information to adjust the prediction equations to specific herd growth rates as well as information needed to calculate the growth rate estimates for different floor space allowances. This tool allows producers to utilize the prediction equations without having ...

Kansas Agricultural Experiment Station Research Reports

A total of 922 pigs [PIC TR4 × (FAST Large white × PIC Landrace), initially 88.3 lb] were used in a 97-d experiment to determine the effects of grinding corn through various roller mill configurations on milling characteristics as well as growth performance and carcass characteristics of finishing pigs in a commercial setting. Pens were randomly allotted to 1 of 4 experimental treatments by initial BW with 11 pens per treatment and 21 pigs per pen. All diets were fed in 5 phases with the same corn-soybean meal-based diets containing 20% dried distiller’s grains with solubles. Experimental treatments included: (1 ...

Kansas Agricultural Experiment Station Research Reports

A total of 3,390 pigs (PIC 337 × 1050; initially 63.2 lb), housed in three replicate barns, were used in this study to determine the influence of increasing organic or inorganic Zn sources on growth performance and carcass characteristics of finishing pigs. A total of 126 pens of pigs were allotted to 1 of 7 dietary treatments, with 24 to 27 pigs per pen and 14 to 17 replications per treatment. All diets contained a trace mineral premix that provided 55 ppm of Zn from ZnSO4. The seven experimental treatments were a control diet with no additional zinc ...
