Principles of fattening mutton sheep in winter

I. the principle of fattening groups

All male and female lambs that are not used for seed and old, weak, thin and remnant sheep that are eliminated can be used for fattening. First, they are castrated, dewormed, ringworm killed and hoof trimmed, and then grouped and grouped according to old and young, strong and weak, male and female. In this way, it is beneficial to the peace of sheep and the growth and development of sheep. But generally speaking, the young sheep gain weight faster and the fattening effect is better than the old sheep. The growth rate of lamb from 1 to 8 months old is the fastest, and it mainly grows muscle. Weaning lamb is selected as fattening sheep to produce fat lamb with good meat quality and high benefit. Therefore, generally, after the lambs are weaned and identified as a whole, the lambs that are not suitable for breeding are grouped and fattened according to their sex and body weight, and the adult sheep are eliminated and fattened in groups according to their age and body weight. this is beneficial to the allocation of feed according to different nutritional requirements.

II. The principle of highlighting benefits

The size of economic benefit is the key to measure the success or failure of fattening mutton sheep, rather than blindly pursuing the maximization of daily gain. Under local conditions, seek the best economic benefits in accordance with the laws of market economy. Especially under the condition of house feeding and fattening, the maximum weight gain of mutton sheep is often based on high concentrate diet, and the maximization of daily weight gain of mutton sheep does not necessarily mean that the best economic benefit can be obtained. Therefore, when setting the expected fattening intensity, we must take the best economic benefit as the only yardstick. According to the feeding standard and the growth and development characteristics of fattening sheep, the diet composition, dietary supply or supplementary feeding quota of mutton sheep should be determined and adjusted in time according to the actual weight gain effect.

III. The principle of house feeding and fattening

When the temperature is low or the pastures, grassy slopes and fields are frozen by snow and ice, sheep can be changed from grazing to house fattening. Mainly feed high-quality dried grass or silage, feed a certain amount of corn, dried melon, sorghum, bean cake and other fine feed every day, but also feed some succulent feed such as carrots and pumpkins to improve palatability and increase the feed intake of sheep. Allowing sheep to eat and drink well in a warm barn can make them grow and grow rapidly and gain weight.

IV. Principle of timely slaughtering

In the production, the production should be organized reasonably and the fattening sheep should be slaughtered in time. According to the growth and development stage at the beginning of fattening sheep, determine the length of fattening period, too short fattening effect is not obvious, too long, the feed reward is low, and it is not economical. Therefore, when the mutton sheep reach a certain body weight after a certain period of time, they should be slaughtered or listed in time, instead of blindly pursuing the maximum weight of the sheep.

V. principle of scale determination

The size of fattening scale determines the amount of profit, generally speaking, the larger the scale, the more profit, but in actual production, it is often counterproductive, because of blind procurement of sheep, greedy for scale and ignoring the operation of the market and the carrying capacity of consumers. It causes the phenomenon of large scale and big loss, therefore, when determining the feeding scale, one is to understand the meat consumption level and personal income of the place of sale, and to make a reliable prediction of the pre-sale price through these; second, we should pay attention to the prices of agricultural products related to animal husbandry, such as corn, soybeans, etc., the price of these products directly affect the fluctuation of feed prices, and it is also a barometer of meat prices. Third, the length and batches of fattening period should be determined according to the quantity and total amount of forage and feed stored. When fattening, under the reasonable and scientific combination of forage and feed, the general fattening period is 60 to 70 days, and the specific fattening time depends on the fatness, size and daily weight gain rate of sheep entering the fattening fattening sheet. from the point of view of economic benefits, the fattening period had better not exceed 90 days.
