Writers are fond of
telling new goat-keepers that our herds are browsers, not grazers. In
other words, goats are supposed to crave tree leaves. But do they
really?
Watching our goats graze,
my answer is --- sometimes yes, sometimes no. If given a choice between
a lush stand of vegetatively growing oats and nearly all tree leaves,
Abigail makes a beeline for the oats. On the other hand, black locust
leaves always hit the spot over vegetation on the ground.
In the end it seems to
come down to succulence, protein, and energy content. Even though goats
are ruminants, their bellies are relatively small compared to those of
cows. And milk production uses up a lot of calories. So a milking doe
like Abigail needs to choose plants of optimal nutrition, which seems to
consist of honeysuckle, multiflora rose, black locust leaves, spring
grass, and oats. She'll eat tidbits of lots of other plants, but those
few offerings seem to make up the bulk of her diet when I allow it.
In the summer and with
insufficient pastures, black locust is the easiest high-quality leaf
matter to wrangle for our goats. Luckily, our herd's pastures are
located in subpar soil, which is the preferred habitat of this
nitrogen-fixing tree.
The trouble is, my current method of cutting one large limb a day for our herd isn't a long-term strategy. Cut limbs do resprout
(as you can see to the right), but I suspect I can only get away with
coppicing a tree once or twice a year if I want it to survive.
On the other hand, goats have such sensitive mouths that they're able to pick off leaves
one at a time, leaving the thorny branches intact. Which makes me think
that if I plan it right, I might be able to bend branches down so
they're within nibbling reach, then let them bound back up to
regrow. Or, since we rotate our pastures frequently, it's possible I
might get away with simply letting tree leaves regrow while the goats
are absent on limbs that are always within goat reach.
Plenty of fun observation
and experimentation ahead as we build the optimal goat pastures. What
fun! I almost miss the days before we figured out the best way to pasture chickens...but not quite.
