1.25 Biochemical background of ketosis in ruminants Flashcards
1
Q
Give the connection between gluconeogenesis and ketogenesis in ruminants
A
NEB = Negative energy balance
2
Q
Ketosis
A
Raised ketone bodies in body tissues
3
Q
Ketogenesis ↑ =
A
Ketoacidosis
Because ketone bodies are acids
4
Q
Give the range of ketosis
A
900mmol - 1400μm = Mild ketosis
> = Severe ketosis
5
Q
Give the types of ketosis
A
- Primary ketosis (↑ energy needed)
- Secondary (Ø enough energy uptake)
6
Q
Primary ketosis
A
- Dairy ketosis - Early lactation in dairy cattle
- Pregnancy toxaemia in ewes carrying twins
7
Q
Secondary ketosis
A
- Starvation
- Diabetes
- Gastrointestinal disease
8
Q
Give the ratio of ketone bodies in:
- Milk
- Blood
- Urine
A
- Milk: 1
- Blood: 5
- Urine: 10
9
Q
Treatment of ketosis
A
- Glucose or
- Propylene glycol
Intravenous
10
Q
Lipid degradation of ruminants
A
11
Q
Draw saturation of unsaturated FA in ruminants
A
12
Q
FA absorption in ruminants
A
- Absorbed from rumen
- Fat
- Intestine
13
Q
Lipid synthesis in ruminants
A
