A cooperative study on the standardized total-tract digestible phosphorus requirement of twenty-kilogram pigs.
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 کاملPerformance and apparent total tract phosphorus and calcium digestibility in grower-finisher pigs fed diets with and without phytase.
The efficacy of a thermotolerant 6-phytase on performance and apparent total tract digestibility (ATTD) of P and Ca was evaluated in 96 crossbred barrows (8 replicates with 3 pigs each) fed 4 diets. Diets based on corn (Zea mays), a heat-treated grain mix, and soybean (Glycine max) meal with recommended [positive control (PC)] or reduced [negative control (NC)] P and Ca levels were fed from 25 ...
متن کاملStandardized Ileal Digestible Lysine Requirement of 6- to 10-kg Weanling Pigs
Corresponding Author: Beob Gyun Kim Department of Animal Science and Technology, Konkuk University, Seoul, Republic of Korea Email: [email protected] Abstract: The objective of the experiment was to determine the Standardized Ileal Digestible (SID) lysine requirement for weanling pigs from 6 to 10 kg of Body Weight (BW). A total of 216 weanling pigs with an initial BW of 6.23±0.93 kg were assi...
متن کاملPhytase improves apparent total tract digestibility of phosphorus and calcium in piglets fed diets with adequate or reduced phosphorus content.
The effect of a thermotolerant 6-phytase produced by Trichoderma reesei on performance and apparent total tract digestibility (ATTD) of P and Ca was evaluated in 192 weaned piglets (randomized block design; 16 replicates; 2 piglets each). Diets based on wheat (Triticum aestivum), barley (Hordeum vulgare), oat (Avena sativa), soybean (Glycine max) meal, and whey protein with adequate [positive c...
متن کاملEffect of phytase on apparent total tract digestibility of phosphorus in corn-soybean meal diets fed to finishing pigs.
Five experiments were conducted to investigate the ability of different phytase products to improve P digestibility in finishing pigs. A corn-soybean meal basal diet containing 0.50% Ca, 0.32% P, and 0.40% Cr(2)O(3) was used to calculate apparent P and GE digestibility. Pigs were individually penned and fed their respective diet for ad libitum intake for 12 d before fecal sampling on d 13 and 1...
