What do microbes do to proteins
What does this produce
Micrbes degrade proteins
- Release proteases, peptidases, deaminases
- Also attached to cell surface of microbe
What does microbes do to CHO
ferment monnosaccs to VFA’s and ATP (for the microbes).
What is NRC
National Research council
what is NASEM
National Academy of Science, Engineering, and math
What are the nutrient requirements do we use regularly?
Protein
Fat
Energy
Minerals and vitamins
What is Toxicity
high nutrient or energy consumed
lower animal performance
What is deficiency
Lower nutrient and energy consumed
Lower animal performance
What affects overall nutrient requirments
Species
Breed
Sex
Physiological state
Season
Previous nutrition\
What is Deaminated
NH3 and C-skeleton for fermentation
What do micrbes do to lipids
Hydrolyze triglycerides, phospholipids
Are fatty acids soulble in h2o
Yes
What are three examples of volatile fatty acids
Acetate
Propimate
Butgrate
How do microbes degrade fiber, starch and sugar
through enzymes
What microbes digest fiber
Cellulolytic
Hemicellulolytic
What is fermentation
Microbial metabolism of organic compounds to obtain energy
What makes ruminants differnet from monogastics
Microbes get first choice
RRO
Fermintation happens before animal digestion or absorption
Stomach secrtions (65-80% digesta located here)
Where is absorption of VFA and ammonia take place
Reticulo-rumen
What controls passage to the abomasum and absorption
Omasum
What does abomasum
Gastric compartment
What do microbes do to lipids
Microbes hydrolyze triglycerides, phospholipids
what do microbes do to non-protein nitrogen
Microbes can synthesize AA
What determines if a feed particle gets fermented or not?
Microbes are unable to degrade the paricle
Microbes don’t have enough time to degrade the particle
It leaves the rumen before being digested or fermented
What are we feeding rumen mirobes
Soluble carbs
RDP
Non-protein N
Fatty acids
