As I began setting aside garden areas to grow fodder crops for goats,
I realized that I needed to do some math. I'm starting to get a handle
on how much supplemental feed Abigail needs to stay in good shape while
pregnant, and I assume she'll need a similar ration while milking. So,
based on that data, how much space would it take to grow the
supplemental feed for one small milk goat during the six-month cold
season?
Abigail didn't seem to
need much other than hay during the beginning of the winter while her
pregnancy was in its early stages, so I figure a sixth of a head of
sunflowers and a carrot per day would provide the bulk of her ration
during that time. In addition, I've been matching her carrot ration with
a similar amount of butternut squash or sweet potatoes lately, figuring
that variety is good for our goat's health, and I'll include mangels in
that extras list next winter. For the sake of easy math, I then doubled
that ration for the late pregnancy and early milking months, resulting
in the feed amounts listed below:
Weekly ration (Oct. - Dec.) |
Weekly ration (Jan. - Mar.) |
Total ration |

1.2 |

Next, the question
becomes, how much space would I need to grow that much feed? Using
low-ball figures on yield for each of our 5-foot-by-3-foot beds (better
safe than sorry), I came up with:
Yield/bed |
# beds |
Square feet |

Heads of sunflowers |

2.9 |

That's really not much
space at all to provide a goat all of her feed except hay! Of course, by
this time next year, Artemesia will be pregnant too, so we'll need to
double those numbers. And we might also need to add on some supplemental
feed for the summer months, so I'll triple the chart's estimates to be
on the safe side. Still, considering that I plant nearly ten times that
much area for me and Mark, a few extra beds of butternuts tucked away in
a corner shouldn't be too much skin off my teeth, especially since all
except the carrots (and possibly mangels) are on my ultra-easy-to-grow
list.
A root veg--oil-seed radish roots? Maybe you really need a hand-cranked chopper?
deb --- I was surprised by the small area too! Of course, that's just the concentrates --- hay would take more effort (or machinery) and area.
Emily --- Yeah, I was wondering how that would factor into her food needs. On the other hand, if we'd been smart and bred her to kid in March, then she'd be going into that voracious season when rich, new grass was on the ground, which cuts back the need for concentrates a lot.
