tepee with a lantern in it in the center of the bunch, a few firecrackers, with here and there a scarecrow around the outer sides, or have a man sleep near them to keep off coyotes. The ewes will generally bunch themselves by moving up around the tepee during the night. If they must be moved to shelter, or for other reasons, let the men start to move the oldest of the day's drop of lambs as soon as the droppers start back toward camp or water in the afternoon, always moving the oldest to the youngest when convenient to do so. Do not allow anyone to move lambs when wet or too young, unless it is necessary to put them into shelter. In that case, try to move them before the storm, rather than after they become wet. New-born lambs still wet, or having become wet by storm, rubbing together, sometimes change their scent, so that quite a number of their mothers become suspicious of them and will not allow them to suck until they become dried, before which time they may die. We have also on several occasions seen ewes become skeptical of their lamb after having cleaned it, simply because the lamb had come in contact with the cleanings of other ewes.
When it is necessary to move new-born lambs, move them slowly and gently to the nearest good shelter. In no case is it advisable to carry lambs around in gunny-sack-full lots. By so doing you are likely to "bum" more lambs than you save. Tie or pen all ewes that do not own their lambs until they do own them. Be sure you are putting THEIR lambs with them. When you have placed the day's drop in good shelter, when you are most sure they are well protected from predatory animals, let them remain quiet for the night. The next morning have someone move them to water. Mix them, when you have to, according to the "table" of these rules. Do not rush the bunches together; get them close to one another, then let them mix themselves. Watch the badger holes. Lambs generally crawl into holes during the cool of night, in hot, sunny days, and during cold, rainy weather.
MIXING TO MAKE UP HERDS.
It is always best to have your two-year-old ewes mixed with the older ewes during their first lambing. However, this should be given consideration in the mixing of the young lambs, of which the following table will give you a very good idea. Do not drop more at any one place than the table allows. Should the drop be heavier than this during the night hours, cut the drop band in two for a few days. In the following table we count ewes only, and it is always best for your per cent to have less if it is convenient to keep them apart longer:
Lambs, hours old |
Mixed twos and older ewes |
Old ewes straight |
---|---|---|
1 to 24 | 120 or less | 150 or less |
24 to 48 | 200 or less | 250 or less |
3 days or more | 350 or less | 450 or less |
From this time on they should be left until they are the following age, when they can be mixed as follows: As ewes know their lambs by scent only during the first four to six days, it should be readily understood that it might become impossible for the ewe to find her lamb should you bunch them sooner than these tables allow, making you many worthless lambs.
Lambs 4 to 6 days old (youngest must be 4 days old), 650 to the band.
Lambs 8 to 12 days old (youngest must be 8 days old), 1,300 to the band.
The above for mixed twos and older ewes. When the herds are made up entirely of ewes past two years old use the following table:
Lambs 4 to 6 days old (youngest must be 4 days old), 750 to the band.
Lambs 8 to 12 days old (youngest must be 8 days old), 1,500 to the band.
These tables should be considered well any time you do any mixing to make up herds. Where you have good feed and water, they will prove very successful. However, as ewes can and will suckle their lambs more readily while in small bands, the development of the lamb will be much more rapid where you are not compelled to bunch them too soon. Let these lamb bunches remain quiet as much as you possibly can. If your feed is poor around the water and the ewes have to leave their lambs to find feed, do not mix so soon nor so many. It may be advisable to move the droppers along a little faster, and by so doing you will leave more feed behind for the ewes with lambs.
DOCKING OR TRIMMING LAMBS.
Lambs should be docked when from six to twelve days old, when convenient in bands of not more than 700. For several reasons it is best to trim them on a cool day before they move around much in the morning. Avoid trimming in the heat of the day. Docking lambs in old corrals is dangerous, because it is unsanitary—many lambs are likely to die if left standing in old corrals after being cut at docking time. Turn each lamb over the fence and out to pasture as you dock it and you will avoid this trouble. When you can so arrange, it is best to leave these trimmed bunches where they are the balance of the day. At least do not overheat them by rushing them around, either before or after trimming. Let them rest a while.
We have used a knife in tailing lambs for years, but find they become a few pounds heavier during the summer season when seared, so advise the use of searing tongs to do the tailing. Keep these tongs red hot, so they will sear and stop all blood. To sear lambs, the docking corral is arranged the same as when you dock with the knife. You simply have an extra man, who places a stove or builds a fire to the right of the person doing the ear-marking and castrating. In this fire or stove the tongs are kept hot, and as the party doing the trimming passes the lamb to the right—the catcher still holding it—along the cutting board, this extra man has the tongs ready to part the tails. One heating of the tongs will sear and part the tails of four or five lambs. You should, however, have at least two or three pairs of these tongs. They are sold at Chicago.
If, after a few days, two or three of your largest lambs become sick, bleed them a little by cutting them under the tail stub. Use a solution of 100 parts water to one part creosote sheep dip, or the same solution of carbolic acid, as a wash to swab wether lambs. This will disinfect all cuts and keep flies from them. You will also save many lambs that have been snagged, dog or coyote bitten, by disinfecting them at once, or within a few hours, with either of these solutions. In castrating young lambs, cut the scrotum or sack off about one-half inch from end, then pinch tight above the testicles and draw them. Part the tails at about the lower end of skin on inside of tail. At this time herd-mark each full band of ewes and their lambs distinctly with a separate mark, so they can be parted in case they mix with another band during the summer season.
PULLING LAMBS—EVERSION OF WOMB.
In pulling lambs from ewes, try to attend to such ewes before the lamb is dead. Get the legs out first; pull slowly and be careful not to jerk—you may pull the lamb bed out of the ewe if you do. Should you do this, or should you find a ewe with her womb
