The silo you are intending to build is too shallow, and would hold only a very small amount of silage. There would be several inches loss of silage before you could start feeding, and you would have to feed at least two and probably three inches off per day in order to keep the food from spoiling. Sixty inches of silage would thus only last about twenty days. Also, the deeper a silo is, the tighter the ensilage is packed and the more will be contained in a cubic foot. The following table will give suggestions as to dimensions:
Diameter. Height. Capacity. Diameter. Height. Capacity. 10 feet 25 feet 36 tons 14 feet 34 feet 115 tons 10 " 28 " 42 " 15 " 34 " 131 " 11 " 29 " 60 " 16 " 35 " 158 " 12 " 32 " 73 " 20 " 35 " 258 " 13 " 33 " 83 "
A cow can consume four tons of silage in 180 days and more or less as you care to feed, so by figuring out how long you will probably feed, you can see the size of silo to build at once.
Soiling Crops in California.
What are the dates for planting crops to be used for soiling in your
State?
We are using Indian corn and sorghums of various kinds for soiling to a certain extent. There is also some cutting and carrying of alfalfa, although most of the alfalfa is pastured. Dates of planting depend upon the frost-free period; sometimes beginning in April, and successive planting for later growth as water may be available for irrigation. There are places where one can see standing corn and sorghum untouched by frost as late as December 1. In other locations the growth of these plants have to be made between May and September. We have also winter-soiling practiced to a small extent in this State and for that purpose rye and barley sown at the beginning of the rainy season are used to some extent.
Brewer's Grains for Cows.
Are sprouted barley grains that may be had from breweries good for milch cows? Will it increase the milk, or will it dry up the cows?
Professor Henry, in his standard work on "Feeds and Feedings," says: "Fresh brewer's grains constitute one of the best feeds for the dairy cow. She is fond of them and they influence most favorably the flow of milk. Fed while fresh in reasonable quantities, supplemented by bright hay or corn fodder for dry feed, the grains being kept in tight feed-boxes which can be kept clean, and with other conditions favorable to the healthfulness of the cow, no valid objection can be raised against this form of feed. From 20 to 30 pounds of wet grains should constitute a day's allowance."
