Short-term fattening technology of sheep in autumn
The short-term fattening of mutton sheep refers to an effective measure to increase the body weight, slaughter rate and economic efficiency of commercial sheep by feeding the commercial sheep three months before sale and adding high-quality forage grass to promote fattening. I. Do a good job in fattening before the preparation of fat sheep short-term fattening has achieved significant results, preparation before fattening is essential. At least do the following preparations: 1. Preparation of sheep house Because it is necessary to feed, it is necessary to have a sheep house, and the breeding density of each sheep accounts for 0.4-0.5 square meters, in order to help limit the movement of the sheep and increase the fattening effect. The location of the sheep house should be selected for ventilation, drainage, lighting, sheltering, and access to grazing land and feed storage. 2, forage, feed preparation Forage, feed is the basis for sheep fattening, every sheep during the entire fattening period to prepare hay 2-2.5 kg per day, or 3-5 kg ​​of silage, or 3-5 kg ​​of ammoniation Feed, etc.; concentrates are prepared at 0.3-0.4 kg per sheep per day. 3. The choice of fattening season is because mutton is mostly used for lamb hot pot, and “mutton hot pot†is eaten in winter and spring. Therefore, the market demand for lamb in winter and spring is the largest. Commodity sheep are more suitable for winter slaughter, so the sheep The fattening season was best in the fall, and the temperature was appropriate during this season. The pasture and crop stalks are abundant, which is conducive to the rapid growth and sales of mutton sheep. 4. Selection of fattening sheep In general, sheep used for fattening should use lambs of the current year and young sheep, followed by sheep and old sheep. After selecting the fattening sheep, the following work should be done: (1) Deworming: Because the parasites in the body are very common, it will seriously affect the normal growth of goats. (2) Castration: For rams that are used for fattening, the rams must be castrated because of the tame traits of the rams after the castration, good meat quality, and fast weight gain. (3) Timely weighing, making a record: that is, weighing the fattening sheep before and after fattening so as to evaluate the effect of fattening and summing up experience and lessons. Second, master the principles of feeding and management 1. Although it is possible to make full use of roughage in the control of roughage and feed ratio, in order to increase the daily gain during the fattening period, certain high-energy feeds must be given. Proper proportion of coarse and coarse, can not only provide energy, but also meet the needs of protein, but also to maintain the normal rumen activity, to ensure the health of the sheep, so concentrate feed to account for 1/3 of the diet is appropriate. 2, protein level protein in the proportion of sheep's diet should be about 8%. 3. Feeding amount and feeding method The feeding amount of the sheep should be determined according to its feed intake, and how much to feed. The feed intake is related to the species, age, sex, physique, feed palatability, and moisture of the sheep. The greater the intake of sheep, the higher the daily gain. The daily intake of hay for hay is 2-2.5 kg, 3-4 kg for fresh green grass and 0.3-0.4 kg for fine material. The feeding method is to feed the concentrate first, then feed the hay or coarse material, and finally drink water. Forage is added at any time to keep the sheep's strong appetite and increase its feed intake. 4, daily management methods This is mainly to minimize sheep movement, reduce consumption, so that the sheep absorb all the nutrients used to increase weight. Autumn fattening, at noon can put the sheep out of the sun or near the short grazing. Short-term fattening must be supplemented with concentrates, and reasonable concentrates can achieve the effect of less material and faster weight gain. It should be noted that seed-like feeds should not be ground too fine so as to prevent dust from being inhaled into the lungs by sheep and affecting health. In addition, when the concentrate is combined with green hay, it is best to add silage to supplement vitamins, or to add complex vitamins and trace elements.
