On a farm of Governor Hoard, in Wisconsin, all the brood sows have for several years been wintered on alfalfa hay of the third cutting, and their drink, without any grain until the last two weeks of gestation. Mr. Hoard says the object was to give the sows a food that should keep them in a non-feverish state and furnish protein sufficient to build the bodies of the forthcoming pigs. (Their “drink” was the skim milk from the dairy.)
“It was a matter of experiment at first, our only guide being what knowledge and reason we could exercise from what we knew, or thought we knew, of the philosophy of gestation. The experiment proved to be a success from the first. The sows went through their work in fine condition, giving milk abundantly. The pigs came with splendid vitality, thus reducing our losses from early death fully 30 per cent over what they had previously been. The hay is fed dry and is thrown into the pen on the feeding floor without any cutting or chaffing whatever. We have sometimes thought we would try the experiment of cutting it into half-inch lengths and moistening it. Possibly it would take less hay in this way. The sows keep in good flesh, fully as much so as we like.”
A Finney county, Kansas, farmer reports having pastured 30 pigs on one acre of alfalfa from May 1st to September 1st, when they weighed 100 pounds each and were in fine condition for fattening. Another Kansas farmer reports keeping 100 pigs from about the middle of April to September on five acres of alfalfa pasture. A little grain during the last two months would have gained him many pounds of pork. Many alfalfa raising pig-growers insist that their pigs can be maintained from May to October on alfalfa for one-half what it would cost for almost any other feed.
The Utah station found that young shoats gained one-third of a pound a day on alfalfa pasture without grain. But the station found also that the gain was not so great in older hogs. A Wisconsin dairyman reported that he kept nine sows all winter and spring on alfalfa hay and skim milk, without any grain, and raised from them 75 pigs, all healthy and vigorous.
The Colorado station considers that a ration of three-fourths corn and one-fourth alfalfa hay is the best for fattening hogs for market, but for young hogs not ready for fattening the proportions should be reversed. The station does not recommend grinding alfalfa hay for hogs, probably on the theory that the hog’s time is not worth much at best.
A VALUABLE FEEDING TEST
The Kansas station in the fall of 1898 made a series of experiments of interest to feeders everywhere. The test was to determine the value of alfalfa hay fed to fattening hogs that were receiving all the grain they would eat. The results are related here in the language of the bulletin:
“The hogs fed in this experiment were bought of farmers, and averaged in weight 125 pounds each. They were placed in lots of ten each, in large pens, having for shelter some sheds open to the south. The alfalfa hay used was of the best quality, carefully cured. Blackhulled White Kafir-corn was the grain used, the hogs being fed all they would eat without waste. The hay was fed dry in forkfuls in a large flat trough. The pigs were given more than they could eat, and they picked out the leaves and finer stems, rejecting the coarser stems. One lot of hogs was fed Kafir-corn meal dry and alfalfa hay; one lot whole Kafir-corn dry; one lot Kafir-corn meal dry, and one lot Kafir-corn meal wet.
“The experiment began on November 24 and lasted nine weeks. By that time the alfalfa-fed hogs became well fattened, and were marketed. We estimated that it would require four to five weeks additional feeding, with ordinary weather, to get the hogs that were fed grain alone into good marketable condition.
“The gain in nine weeks from the different methods of feeding were as follows:
