Comparison of standardized ileal amino acid digestibilities in protein supplements and cereal grains for weaned pigs.
Standardized ileal digestibility (SID) of AA in protein ingredients and grains was determined in weaned piglets (5 kg initial BW) using the difference method. Animals were fitted with a simple ileal T-cannula on day 24 or 25 of age. A synthetic diet based on corn (Zea mays) starch and casein was either supplemented with an extruded soybean (Glycine max) meal (ESM), rice (Oryza sativa) protein c...
متن کاملHuman Metapneumovirus in Turkey Poults
This study was conducted to reexamine the hypothesis that human metapneumovirus (hMPV) will not infect turkeys. Six groups of 2-week-old turkeys (20 per group) were inoculated oculonasally with 1 of the following: noninfected cell suspension; hMPV genotype A1, A2, B1, or B2; or avian metapneumovirus (aMPV) subtype C. Poults inoculated with hMPV showed nasal discharge days 4-9 postexposure. Spec...
متن کاملDetection Methods for Mycotoxins in Cereal Grains and Cereal Products
Analytical methods for mycotoxins in cereals and cereal-based products require three major steps, including extraction, clean-up (to eliminate interferences from the extract and concentrate the analyte), and detection/determination of the toxin (by using suitable analytical instruments/technologies). Clean-up is essential for the analysis of mycotoxins at trace levels, and involves the use of s...
متن کاملTrichothecenes in Cereal Grains
Trichothecenes are sesquiterpenoid mycotoxins associated with fusarium head blight (FHB) of cereals, with worldwide economic and health impacts. While various management strategies have been proposed to reduce the mycotoxin risk, breeding towards FHB-resistance appears to be the most effective means to manage the disease, and reduce trichothecene contamination of cereal-based food products. Thi...
متن کاملSupplementary biotin decreases tibial bone weight, density and strength in riboflavin-deficient starter diets for turkey poults.
1. Growth and skeletal responses to different dietary concentrations of riboflavin and biotin were compared in turkey poults from hatch to 21 d of age. The birds were fed on a turkey starter diet with different concentrations of supplementary riboflavin (0, 20 and 40 mg/kg) and biotin (0, 0.3 and 0.6 mg/kg) in a factorial design. 2. Poults fed on diets with no supplementary riboflavin had poor ...
