90 Efficacy of Different Phytases on Growth Performance, Energy and Nutrient Digestibility and Bone Quality of Weaned Piglets Fed a Wheat-Corn Soybean Meal Based Complex Diet
Abstract:The study determined efficacy of different phytases in diets without inorganic phosphorus (P) in piglets. Piglets (initial body weight 9.7 ± 1.2 kg) were randomly assigned (2 piglets/pen), based on sex and body weight over 6 diets. Positive control (PC) corn-wheat based diet was formulated to meet NRC specification. Negative control (NC) diet was formulated without inorganic P (-0.16% STTD P), with reduced calcium (Ca; -0.15%), net energy (-33 kcal/kg), and standardized ileal digestible amino acids (average -0… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
