The hog is more of a herbivorous animal than is generally credited.
There is hardly any grass or grain, but what hogs will eat when green, and
there are many weeds on which they will feed. They will even eat and
relish dry hay, such as cowpea hay, soja bean hay, beggarweed hay, and in
fact any legume hay, when properly cured.
Uses of Green Feed
These grasses and hays, however, will not entirely replace the grain
in the feed; but they will replace a part of it, and at the same time increase
the gain that it is possible to get from a given amount of grain. For
instance, if 100 pounds of corn fed alone will produce 8 to 10 pounds
of pork, this same amount of corn when fed with some green feed will pro-
duce from 12 to 15 pounds of pork. This is not mainly due to the food
value of the green stuff, but rather that the green feed regulates and tones
up the digestive and circulatory systems and keeps them in good healthy
The hog is much like any other animal with regard to feed. That is,
a variety of feeds is appreciated, especially when they are given in a clean
dry place, and not thrown out in the mud and water, as is often done.
The following is a list of valuable forage crops for hogs in Florida. The
crops on this list will give pasture throughout the entire year.
1.-Dwarf Essex rape may be planted any time from September to No-
vember 15. From eight to ten weeks after planting it should give good
pasture, and will continue to furnish good grazing until the middle of March.
Rape will stand several degrees of frost, and so makes an excellent winter
pasture in Florida. With the pasturing properly managed and liberal ferti-
lizing, three good crops may be had during the growing season. Yields of
fourteen to sixteen tons per acre have been secured on the Experiment
Station grounds. Rape costs from $1.30 to $1.60 per ton, according to the
yield obtained and the cost of fertilizing.
2.-Japanese cane may be planted any time from November 15 to April
November 5, 19 10
1. It will give abundant grazing from the following November to March 1.
Perhaps we have no other forage crop that will produce such an enormous
growth of green feed as will Japanese cane. It may be pastured, or cut and
fed to hogs in the lot. A yield of 20 to 25 tons per acre is not too much
to expect. In an experiment conducted at the Experiment Station last year,
the yields per acre from eight plots were from 16 to 27 tons, with an average
yield per acre of 19.8 tons. The cost of growing this crop is about $30.00
per acre, for the first year. The cost per acre for the following years should
not exceed $12.50 to $15.00. After the first year it can be produced for from
40 to 60 cents per ton.
3.-Rye, oats, and barley may be sown during September and October.
With favorable conditions they should furnish good pasturage in from 8 to
10 weeks. They should, if not over pastured, continue to give good pasturage
until the following April.
4.-Sorghum imay be planted in the latter part of February or early in
March. With good growing weather, it should furnish good pasturage until
frost kills it in November. Sorghum will yield from 8 to 16 tons per acre.
The cost of growing it varies from $12.00 to $15.00 per acre.
5.-Chufas and peanuts may be planted in March or April, and will supply
feed from August to December.
6.-Sweet potatoes may be planted any time from April to July 10, and
will give an abundant pasturage from October to December. A yield of
150 to 300 bushels per acre has been secured on the Experiment Station
7.-Velvet beans should be planted from March 15 to May 1, and will
furnish good grazing from November to March. (See Bulletin 102.)
8.-Cowpeas and soja beans are also useful. They may be planted any
time from April to July. In from two to three months they will give an
abundance of feed.
9.-For permanent pasture it is doubtful if we can get anything better
than Bermuda and Johnson grass. These do not furnish pasturage for the
entire year, but can be depended upon from early spring until late fall.
To grow these crops successfully, the ground must be thoroughly prepared,
given a liberal application of fertilizer, and properly cultivated during the
growing season of the crop.
