Meta-analysis of effects of microbial phytase on digestibility and bioavailability of copper and zinc in growing pigs.
A meta-analysis was conducted to determine the effect of microbial phytase in pig diets on digestibility and bioavailability of Cu and Zn. Studies (n = 22) into effects of microbial phytase on digestibility and plasma levels of Cu and Zn were included in a dataset and regression analysis was performed to quantify the effect of Aspergillus niger derived 3-phytase in studies (n = 14) with a maxim...
متن کاملEffect of microbial phytase on apparent digestibility and retention of phosphorus and nitrogen in growing pigs
Six female pigs of approximately 50 kg BW, fitted with simple T-cannula in the terminal ileum, were used to study the effect of microbial phytase on apparent total tract digestibility and retention of P and N. Three P-adequate diets (digestible P concentration 2.3 g/kg) containing barley (B), soybean meal (S) or their mixture (BS) with or without phytase supplement (1 000 FTU/kg) were fed to pi...
متن کاملBioavailability of dietary cyanocobalamin (vitamin B12) in growing pigs.
The present project aimed to estimate bioavailability of dietary vitamin B(12), for which little information is available in growing pigs. Two approaches, each using 2 quantities of dietary cyanocobalamin, were compared; the first was based on whole body retention for 8 d and the second was based on nycthemeral portal net flux of vitamin B(12). In the first trial, 15 blocks of 3 pigs (31.7 ± 0....
متن کاملThe effect of microbial phytase on true and apparent ileal amino acid digestibilities in growing-finishing pigs.
Ten 56-d-old, 15-kg barrows were surgically fitted with a postvalvular T-cecum cannula at the ileo-cecal junction to evaluate the effect of microbial phytase on apparent and true ileal AA digestibility and N utilization. A semipurified cornstarch- and soybean meal-based diet was formulated to contain 3.4 Mcal of DE/kg, 17.0% CP, 0.8% Ca, and 0.6% P but had a low phytate-P concentration (0.13%; ...
متن کاملEffect of Dietary Organic Zinc and Prebiotic on Productive Performance and Immune Response of Growing Quails
The aim of the present study was to investigate the possibility of improvingproductive performance and immunity of growing Japanese quailreared during summer in Egypt by supplementing the diets with organic zinc (Bioplex zinc) and prebiotic (mannan oligosaccharides). Diets were a basal diet or the basal diet supplemented with 20 mg Bioplex zinc (3.0 mg Zn) (Zn1), 40 mg Bioplex zinc (6.0 mg Zn) ...
