CCT- Alternative Systems: Multi-Species Flashcards
Idea behind mixed-species grazing
A producer can take advantage of the different foraging habits and preferences of ruminant and non-ruminant herbivores
How does a producer accomplish the goal of mixed-species grazing?
By matching the composition and quantity of animals to the available forage resources
How is mixed-species grazing done in the U.S?
The addition of extra sheep or goats with different foraging preferences to a pasture that is already stocked with an optimal number of cattle
What is the most common final result of mixed-species grazing?
Sustained or improved cattle production, with an added bonus of the extra off take from the sheep and goat, resulting in a greater profit per unit of land
Additional unforeseen benefits of mixed-species grazing
Better management of internal parasites (bloodworms) and protection of small ruminants against predators (dogs, coyotes)
Is diet selection related to feed availability? How so?
Yes. Grazing animals will tend to consume the predominant species that is growing in the pasture or their ecological niche
How can the difference in plant selection during foraging be used?
These differences in eating habit or foraging behavior can be used to successfully manage existing agropastoral resources, or even to improve existing areas of unimproved countryside
General observation across Animal Kingdom that has to do with the relationship between the animal’s size and its foraging behavior
The larger the ruminant, the more likely it is that it will be classified as a bulk and roughage grazer, whereas the smaller the ruminant, the more likely it is that they fall within the intermediate/concentrate feeder herbivore category
What else determines to a great extent some of an animal’s foraging preferences and habits?
The anatomical and physical agility of an animal
Examples of anatomical and physical agility
A goat has greater control and use of the muscles that make up the lips around its mouth, compared with a dairy cow (sheep are intermediate). There are also digestive tract differences and the ability to stand on hind legs to browse
Which animals are more resistant to certain naturally-occurring plant-protecting compounds than others?
Goats and deer more resistant than cattle and even, sheep
Under most Southern grazing conditions, you can add how many goats per cow without adversely affecting beef cattle production?
1-2
Benefits of Mixed-Species Grazing
Is dependent on the forage and animals available, Can assist in weed control and pasture reclamation, Can assist in the management of internal parasites, Can provide protection against predators
Mixed-species grazing has its greatest benefits when..?
Forage availability is not limited and types or kinds of forages vary
What happens when forage varies and is not limited?
Highly-selective animals (goats) select forbs and browse, leaving grass for the bulk and less selective grazers (cattle). Goats and cattle under these conditions, have little competition for available forages, and instead complement one another
