Mr. F. S. Kirk of Oklahoma, [mentioned] in Chapter III, pastures his cattle on alfalfa in fall and spring, but does not give them access to his meadows in the morning until the dew has dried off, and for only twenty or thirty minutes the first day or two; then for an hour or two for a few days, and after that they are left in the pastures until sundown.

GENERALLY DANGEROUS TO SHEEP

Experiments with sheep seem to be even more disastrous than with cattle. In an investigation conducted by the Colorado station, losses were reported by nearly every man who had pastured sheep on alfalfa. Some lost but one or two, while others lost forty or fifty. A few reported that each spring they lost a few sheep the first day they were on the pasture, and then no more, and that the losses of old sheep were of less importance than the growth of the lambs, these being seldom affected by bloat. Most, however, advised that the old should not be turned on alfalfa under any circumstances, but that lambs, if well fed in the morning, let on the alfalfa after the dew was off and then kept there night and day would do well, and the loss be smaller than that in a normal season from other causes. J. E. Wing states that his loss from pasturing lambs on alfalfa in Ohio is less than it formerly was from one or two parasitic diseases that never trouble alfalfa-pastured lambs. He gives his lambs a full feed in the morning, turns them on the alfalfa field about ten o’clock, and leaves them there continuously until September. He begins the pasturing just before the seasons first growth of the alfalfa blooms.

While by no means without risk, pasturing sheep on alfalfa is not always necessarily fatal and the following, related in the Breeder’s Gazette by Mr. C. H. Williams of Powell county, Montana, is interesting:

“We have been pasturing sheep in large numbers on alfalfa for the past eight years. We have lost from bloat as many as 26 in one day from a flock of 1600, but we seldom lose one now. We find they are much more apt to bloat on windy days; more especially if the wind blows from the south and is soft and balmy. This may seem strange, but we believe it a fact. We have in our employ a shepherd who has during the greater part of his life herded sheep on alfalfa in the vicinity of Pau and d’Oloron, France. The day we lost 26 ewes from bloat this man was several miles from the home ranch. When visited by the camptender he remarked: ‘This will be a bad day for the old ewes on the alfalfa.’ Why so? ‘Because the wind is soft and warm,’ said he. That afternoon we found 26 dead.

“Our French shepherd has a simple and never failing remedy for bloat from alfalfa or clover. It is simply a half-pint of sweet milk administered to the animal when found bloated. I saved a fine ram lamb the other day. He was fearfully bloated, unable to walk and scarcely able to breathe. I found an old can in the road, hastened to the pasture, milked a half pint of milk from a cow, set the lamb on his rump and poured the milk down his throat. In a half hour he was all right and following the flock. Milk from a ewe will answer just as well. We have adopted the following rules: Never allow the sheep to go on alfalfa pasture when very hungry; if possible get a little dry feed in their stomachs in the morning before going to the alfalfa; watch them closely on windy days, and have the herders carry a bottle of sweet milk.”

A POSSIBLE EXPLANATION

The most of the losses reported were of animals which had been taken off the pasture at night and turned back the second morning when hungry and eager to graze. Yet there are reports of severe losses the first day, even after a full feed. Possibly it will be found that the animals that suffer from bloat are not in good physical condition, and are more nervous and greedy in their habit of eating than those not affected. It may be that an intelligent sorting of the animals to be turned on the pasture might save loss. It is also quite generally believed that alfalfa growing on uplands is less liable to cause bloat than that raised on bottom lands.
