Study Notes

Factors Influencing Diet Selection

Goats, cattle, and sheep select forage based on various factors, including:
- Species of plant available
- Season of year
- Content and position of clover
- "Presentation" of forage: zero grazing, species in rows, mixed sward, species offered together
- Sward height, biomass, stocking rate
- Condensed tannin content of forage
- Dry matter content
- Odor and flavor
- Previous experience with forage
- Animal breed, gender, age, and physiological state
- Buccal architecture and tooth integrity
- Grazing height: bipedal versus quadripedal

Goats Select Plants Based on Tannin Content

Goats select plants with high amounts of condensed tannins
Goats have the capability to detoxify tannins
Goats eating high amounts of tannins can lead to decreased intake of other essential nutrients

Forage Digestion and Intake in Goats

There is limited conclusive evidence to suggest that goats digest forage better than sheep
No evidence that goats eat more of a given forage than sheep
A study showed goats grazed for a longer duration than sheep, but this may be due to a preference for different forage species.

Supplementary Feeding under Field Conditions

Supplementary feeding:
- Goats select hay with a high concentration of condensed tannins
- Goats often prefer legumes over grasses, possibly due to forage quality and palatability.
