A cooperative study on the standardized total-tract digestible phosphorus requirement of twenty-kilogram pigs1
A cooperative study comprising growth performance, bone mineralization, and nutrient balance experiments was conducted at 11 stations to determine the standardized total-tract digestible (STTD) P requirement of 20-kg pigs using broken-line regression analysis. Monocalcium phosphate and limestone were added to a corn–soybean meal–based diet at the expense of cornstarch to establish 6 concentrati...

متن کاملTrue digestible phosphorus requirement for twenty- to forty-kilogram pigs.
The objective of this study was to determine the true digestible P requirements of 20- to 40-kg pigs by the broken-line regression analysis of growth performance using 6 levels of true total-tract digestible P. In Exp. 1, 24 barrows (initial BW=25.2±1.0 kg) were used to determine the true total-tract digestibility (TTTD) of P in monocalcium phosphate using the regression method. The dietary tre...
متن کاملTrue digestible phosphorus requirement for forty- to eighty-kilogram pigs.
The objective of this study was to determine the true digestible P requirement of 40- to 60-kg (Exp. 1) and 60- to 80-kg (Exp. 2) pigs by broken-line analysis of growth performance data using 6 levels of true digestible P. In each 3-wk experiment, 108 barrows and gilts were used, and 6 levels of monocalcium phosphate were added to a corn-soybean meal-based diet to establish 6 graded levels of t...
متن کاملCommercial validation of the true ileal digestible lysine requirement for eleven- to twenty-seven-kilogram pigs.
Five experiments utilizing 3,628 pigs were conducted to determine the true ileal digestible (TID) Lys requirement for 11- to 27-kg pigs fed corn-soybean meal diets. In Exp. 1, 216 barrows (initial BW = 11.5 kg) were used, with dietary TID Lys levels from 1.05 to 1.40% TID Lys (0.07% increments). All diets were isocaloric (3.42 Mcal of ME) and contained the same inclusion of soybean meal (33.1%)...
