In the spring of the year in India it is common to give horses green wheat, oats, or barley. This is cut in the straw from the time it is about a foot high until the grain begins to ripen, a period that lasts about a month or six weeks in the Punjab--from the middle of February till the end of March. This green food is called by the natives "khawid," or "khasil." It has an excellent effect on the system, and is what is used by the native dealers to get their horses into condition for sale. Too large a quantity should not be given at first, as it is likely to cause diarrhœa; about 4 lbs. daily being sufficient at first, but it may be increased up to double this amount if it agrees with the animal. Care should be taken that the green food is only given when young and the straw tender, for when it gets ripe, and the straw woody and hard, it is very indigestible, and a common cause of intestinal obstruction and colic. In some parts green barley is given in the same manner, and when it is young it is as good as wheat or oats; but when it begins to ripen it should be stopped, as the awns or beards begin to get hard, and not only are they likely to choke the horse, but to cause dangerous intestinal obstruction. Oats can be given much longer than barley or wheat; in fact, as I have said, ripe oats are cut in the straw, and used as hay in many parts of the world. The green crop must be purchased standing from a cultivator, and this is best arranged through your head "syce." It is sold by measurement, a patch in the field being marked out; or else the grass-cutters go and cut as much as is required daily, the whole amount used being afterwards measured up and paid for at the fixed bazaar rate, or, as it is termed, the "nirrick."
Natives are very fond of giving horses green gram, but it is a most dangerous custom. It is most indigestible, the stalk when green being full of a strong tough fibre. The sap and leaves have a peculiar irritating or almost corrosive property, and in the spring of the year many fatal cases of intestinal disease are caused by it.
Carrots are plentiful all over Northern India. They come on in the spring, and are an excellent green food. They can be bought very cheaply, and if kept in a cool, dry place, can be stored for a considerable time; but they require to be turned almost daily, or they will get rotten. When used they should either be washed to remove the earth, or, as in the East this is quite dry, knocked with a stick to remove it. They should be given whole, or else cut into long slices, not across into lumps. This latter practice is dangerous, as horses are thus inclined to bolt them whole, and the short round lump is likely to stick in the throat and cause choking.
