Sources of Calories and Critical Points
Text
Transcript
Follow along with the audio...
- Soluble Carbohydrates (Starch)
- Insoluble Carbohydrates (Fiber)
- Fat
- Protein
Soluble Carbohydrates
- Main source for anaerobic metabolism
- Glycogen, glucose
- Highly digestible
- High insulin spikes
- Spirited horse
Insoluble Carbohydrates
- Fiber, volatile fatty acids
- Good source of calories if solubility is increased (e.g. beetpulp)
- Digestibility of fiber is increased on high fat diet
Fat
- Primary energy source for aerobic metabolism
- Highly digestible
- Minor changes in insulin
- Calmer horse
- Increase digestibility of fiber
- Increase stamina
- Improve quality of haircoat
- Glycogen sparing effect
Protein
- Requirements increase with exercise but NOT protein
to calorie ratio
- Metabolically expensive source of energy
- Muscle build up and repair
- Quality of Protein/Amino acid profile
- 40g Protein/Mcal (adult horse)
- Omolene 200, Strategy, Race Ready
- 50g Protein/Mcal (growing horse, lactating mare)
- 12-14% CP is necessary
