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.
