Turns out just about every livestock animal enjoys bamboo at different stages of its growth. Chickens will eat new shoots, cows/horses will graze the foliage and goats will browse any part of it that isn’t overly mature/woody.
I’ll always remember a poem from one of my rather-hippie forest ecology professors:
“Sedges have edges, rushes are round, grasses have joints unless there are cops around.”
Therefore, bamboo is technically a grass!
Found on bamboofarmingusa,com, 2 laboratory analysis reports were shared that break down the nutrient content of bamboo.
From Dairy One Forage Testing Laboratory (PDF Link):
From the North Carolina Department of Agriculture and Customer Services:
The crude protein figures above are high enough to be considered a “Premium” grass hay by USDA guidelines (retrieved from Oregon State University). Bamboo requires significant amounts of nitrogen so some sort of legume ground cover (likely peas or clover) would be a natural companion for the bamboo stands.
Letting animals graze bamboo also has the subjective benefit of breaking the monotonous boredom of extended hay feeding. As bamboo is an evergreen perennial, the stands could be opened to grazing in winter. I am not sure how nutrient composition changes with winter dormancy though.
Containing the potentially invasive bamboo:
Growing up in a metropolitan area that has spent countless resources battling the encroachment of bamboo, I want to take steps to ensure it remains contained. Originally meant for containing hops plants from taking over the garden, physical root barriers were actually invented with bamboo in mind.
Here are my two favorites on Amazon:
Time will tell how this experiment goes!
A friend brought up an interesting point in a comment on yesterday’s blog post. There is a species of bamboo native to Virginia and the Southeast US called Giant Cane. He provided a descriptive PDF from the USDA that explains the historical value and use of the plant. My favorite passage states:
According to environmental
historian Mart Stewart (2007), “Modern studies
have established that cane foliage was the highest
yielding native pasture in the South. It has up to
eighteen percent crude protein and is rich in
minerals essential for livestock health.” Livestock
eagerly eat the young plants, leaves, and seeds and
stands decline with overgrazing and rooting by hogs
(Hitchcock and Chase 1951).
Which demonstrates the plant is on par with bamboo as a nutrition source for livestock. Not to mention the renewable building material provided by mature stems. I could build chicken coops, green/hoop houses, storage sheds, etc. Interesting stuff to say the least!
