Specialty Processing
Dehulling is used for? on what plants?
Protein, some seeds have lots of hulls
Dehulling material can increase nutrient content
Technology ranges from very simple to complex
Simplest process is to crack the seed and seperate hulls
Peas, lentils, soybeans, canola/camelina/flax seed
What is deoxynivalenol?
Infected wheat grains have reduced density and appear white to pinkish, shrunken, and chalky
Feed safety is?
assurance that feed, administered according to its intended use, will not cause adverse health effects to the animals or to people
Feed program activities in Saskatchewan includes
Monitoring of feeds via random sampling and analysis for the presence for the analysis for the presence of chemical residues, pesticides, heavy metals, mycotoxins, and salmonella
Fiber modification is?
The most underutilized ingredients are high fiber by-products
there has always been a desire to use them more effectively but difficult
Need to de-lignify material and open up cellulosic structure
Practices to reduce DON
Genetic selection of hybrids
After Harvest processing - density segregation, colour sorting
Feed assure is?
Full HACCP, program of processers and controls customized to feed
developed by ANAC in 1999
brings high safety standards to livestock feed prodcution
What is the feed ban of 1997
Amendments to the health of animals regulations in august 1997 banned feeding prohibited material to ruminants
prohibited material = anything that contains proteins that originated from a mammal other then a porcine or equine
Prohibited material does not include milk, blood, gelatin or fat
Steam Explosion is?
alternative method to de-lignify hemicellulose
high pressure, high temp water penetrates micropores in fiber
Rapid release of pressure results in water conversion to steam and pressure blows fiber up from within
Air fractionation is?
Uses an air stream to separate grain into fractions based on relative grain density differences
Elements of the feed assure program are
Managment commitment
Biosecurity
Feed defense
crisis management
Premises
The Canadian feed ingredient table (CFIT) is?
A document that lists and describes all approved single ingredient feeds
reduction of Mucilage done by?
Heat treatment degrades mucilage in camelina seed
NIRS use in fusarium?
Sorts grain based on density or chemical composition using near infrared spectroscopy
What is HACCP
Hazard analysis critical control point
designed to provide safe food for astronauts to prevent foodborne illnesses in space
What is the compendium of medicating ingredients brochure?
Mixed feed cannot contain medicating ingredients of a brand or level outside of the CMIB unless the feed is a custom mediated feed
Extrusion of Faba beans helps?
Reduce resistant starch, reduce NDF and ADF, increased AMEn in broilers
Combination sorting aspects
The combination of air fractionation and BoMill
To improve the recovery from fraction 3
When conducting a hazard analysis in a feed mill what should be included?
A) all incoming ingredients
B) all processing steps
C) all packaging materials and processing aids
D) all of the above
E) none of the above
D) all of the above
