Sheep can be supplemented at the lamb stage

Span supplementation refers to a technique for feeding lambs to supplement lambs at places where ewes are concentrated. The purpose of supplementing the barriers is to speed up the growth of lambs, reduce the size difference between single lambs and twin lambs and lambs born later, and lay a good foundation for improving fattening effect, especially shortening the fattening period. At the same time, it also reduces the frequency of lambs' licking of ewes so that the ewes' lactation peaks stay longer.

How to do a good job feeding the barriers, the farmers first need to figure out which sheep need to supplement feeding. Generally considered to include lambs who are scheduled to be weaned at 2 months of age, lambs that are scheduled to have a three-year ewes group, lambs that are born in winter, lambs of purebred ewes, lambs of multiple ewes, and people born after the lambing period. Lambs are all sheep belonging to the category of supplementary feeding.

To grasp the feeding time of the fence. Larger sheep generally start feeding at 15 to 21 days of age. If the lambing period lasts longer, the lambs are not born at the same time and can be carried out in groups of lambs. Smaller sheep farmers can choose to start when they find that the lamb has a feed action, and the earliest one can advance to the lamb when it is 10 days old.

Feeding the lambs in the stalls is particularly important in the mix of feeds. The roughage supplemented by lambs is best to use hay or high quality hay. Lambs are eaten freely by using a straw frame or a hanging handle. Concentrates include corn, soybean cake, bran, etc. The corn supplemented by lambs before 1 month of age is It is advisable to use large pieces of crushed granules. Afterwards, it is better to use whole grains of corn. Pay attention to adjusting the amount of feed for roughage and concentrate feeds according to the season. For example, in the early spring when lambs are fed, before the germination of green grass, the hay should be dominated by alfalfa, while the mixed concentrate is mainly corn. The late spring lamb supplementation time during the height of the grass, can not feed hay, but in addition to corn in the mixed concentrate addition of appropriate amount of bean cake, in order to maintain dietary protein levels of not less than 15%.

When feeding, put some corn and soybean cake in the feeding trough during the day. Every day, regardless of whether the lamb is eaten, all are replaced with new ones. After the lamb learns to eat, it will be fed daily on a daily basis. The average daily food intake is 40 grams to 50 grams per day, and 300 grams to 350 grams in the later period. The total consumption of the mixture is from 8 kilograms to 10 kilograms. When feeding, it is better to discharge once a day and the lambs eat within 30 minutes. Time can be arranged in the morning or evening, but with better light. During feeding, if the lamb is found to be unfit for feed, the type of feed can be changed.

Two feed formulations for reference.

Feed formulations in areas that do not have feed processing conditions: 60% corn, 20% barley, 10% bran, 10% bean cake. Every 10 kg of the mixture is added with 0.4 g of chlortetracycline or oxytetracycline, a small amount of bone meal, and the whole grain is mixed well.

In feed formulations with feed processing conditions: corn 20%, bran 10%, barley 20%, bean cake 10%, bone meal 10%, molasses 30%. For every 10 kilograms of concentrate, add 0.4 g of chlortetracycline or oxytetracycline. The above raw materials are mixed in proportions to make pellets, preferably 0.4 cm to 0.6 cm in diameter.
