Exam #2 prep Flashcards
Gut sounds in the horse
Borborigmus
can usually be prevented with a vaccine
Enterotoxemia
Found in between of SI villi - produce mucous
Crypts of Lieberkuhn
Found on the wall in SI - produce mucous
Brunner’s Gland
Activate trypsinogen to trypsin
Enterokinase
villi vessel carries nutrients to the blood
Arteriole
Believed to house good bacteria, vestigial organ
Appendix
Villi vessel carries nutrients to the lymph
Lacteal
Brush border
Microvilli on villi
Toxic, carcinogen metabolite of alcohol
Acetaldehyde
Vit. B12 needed for function
Methylmalonyl Pathway
Low milk fat
low acetate
ketosis
hepatic lipidosis
Lack of rumen fill, too much concentrate
Displaced abomasum
Majority of digestion occurs
Jejunum
Mixing bowl, neutralization
Duodenum
Predominantly absorption
Ileum
Escaped rumen bugs
Parakeratosis
High fiber pellet diet over several years
malformed papillae
Halver Speaker
MAZURI
What is the reason ruminants need long stem hay?
scratch factor, papillae health
What is the reason horses need long stem hay ?
gut fill
What causes liver abscesses?
rumen microbes escape from rumen
Who has a longer small intestine? horse or cow and why ?
cow - fermentation happens before small intestine
Llama gastric stomach
Lower 1/5 compartment III
Avian gastric stomach
Proventriculus
Horse gastric stomach
Stomach
Sheep gastric stomach
Abomasum
Inability to eructate gas
Bloat
50:40:25
acetate:butyrate:propinate in forage diet
65:25:10
acetate: butyrate: propionate: in concentrate diet
Butyrate
4 carbon short chained fatty acid
2 carbon short chained fatty acid
acetate
3 carbon short chained fatty acid
propionate
Why do dairy producers place a small magnet in the reticulum of their animals?
Hardwear disease. nails, tiny pieces of metal
Source of PVT TIM HALL for ruminants ?
microbial proteins or microbes
Three microfauna ?
bacteria, protozoa, fungi
smallest but greatest number of microfauna?
bacteria
largest microfauna
protozoa
what microfauna is responsible for splitting fiber particles apart?
fungi
How does rumensin increase animal gain and performance ?
- increase propionate
- decrease gram positive, increase gram negative
How much absorption does villi provide
30x
microvilli absorption
60 x absorption
rumen villi
visual
duodenum- microvilli
microscopic
mucous function
protects from digestion
NAFL
non-alcoholic fatty liver
NASH
non-alcoholic steatohepatitis = inflammation
cirrhosis
scarring - not reversible
The liver is the…
HUB, all blood goes through the liver
stores bile from liver
gall bladder
endocrine internal
Glucagon & Insulin beta
exocrine external
Bicarbonate - neautralizes ph
Synergistic Relationship “Symbiotic”
ruminants and microbes
Salivary amylase stops working in
acidic stomach
what species dont have a gall bladder
horse, deer, parrots, rats
quick diet change
= bacteria change
Microbe population functions
ferment and produce gas and VFA’s
inoculating hindgut
starving horses and foals will eat feces
small intestine
digestion
cecum
fermentation
large intestine
resorption and absorption
Enterolith
mineral imbalance = rocks
high grain
founder, DOD, colic
Large intestine main function
Reabsorption of water from food and mineral uptake
e-coli
makes vitamin K
overall function of blood
maintain homeostasis of the body
colectomy
removal of colon
Gnotobiotic
no microbes
dietary fiber
in fruits and vegetables, microbes need fiber rich food to protect the gut
Amphibians
skin apart of their immune system
Dysbiosis factors
energy drinks, artificial sweeteners
carbohydrates
contain hydrogen and oxygen in the same proportion as water (2:1)
simple carbohydrates
monosaccharides
complex carbohydrates
polysaccharides
starch vs. cellulose
difference is the B 1-4 bond just flipping that bond
C6H12O6
glucose
