_Linseed_ is one of the most valuable kinds of food which could be given to fattening animals. Its exceedingly high proportion of ready-formed fatty matter, the great comparative solubility of its constituents, and its mild and agreeable flavor, constitute it an article superior to linseed cake. The laxative properties of linseed are very decided; it should therefore be given only in moderate quantities. As peas and beans exercise, as I have already stated, a relaxing influence upon the bowels, a mixture of linseed and peas or beans would be an excellent compound, the laxative influence of the one being corrected by the binding tendency of the other. Linseed being one of the most concentrated feeding stuffs in use, it will be found an excellent addition to bulky food, such as chaff and turnips. Linseed oil has been used as a fattening food, but there is nothing to be gained by expressing seeds for the purpose of using their oil as a feeding material. When hay is scarce, and straw abundant, the latter may be made almost as nutritious as the former by mixing it with linseed, and steaming the compound. A stone of linseed and two cwt. of oat-straw chaff, when properly cooked, constitute a most economical and nutritious food. Mr. Horne, who experimented with linseed two or three years ago, obtained results highly favorable to the nutritive value of that article. Six bullocks were selected, and each animal placed in a separate box. They were fed with cut roots--at first Swedes, then mangels and Swedes, and lastly, mangels alone: in addition, there were supplied to each 6 lbs. rough meadow-hay reduced to chaff, and 5 lbs. oil-cake, or value to that amount. They were divided into three lots, two in each. Lot 1 had 5 lbs. oil-cake for each animal; lot 2, barley and wheat-meal, equal in value to the 5 lbs. oil-cake; and lot 3, an equal money's worth of bruised linseed. The oil-cake cost £10 16s. per ton, the mixture of barley and wheat £8 15s. per ton, and the bruised linseed £13 per ton. The experiment lasted 112 days, and at its close the results, which proved very favorable to the bruised linseed, were as follows:-- Increase in live weight. Lot 1. Oil-cake 637 lbs. Lot 2. Wheat and barley-meal 667 lbs. Lot 3. Bruised linseed 718 lbs. During the 112 days each bullock consumed 5 cwt. oil-cake (or an equivalent amount of linseed or wheat and barley), 6 cwt. hay, and 90 cwt. of roots. The average increase in each animal's weight was 337 lbs. = 224 lbs. _dead_ weight. The economic features of this experiment are best shown in the following figures:-- FOOD CONSUMED. £ s. d.
