Considering the high cost of housing and raising sheep, in order to improve the fattening efficiency, we should make full use of natural pasture, straw, leaves, agricultural and sideline products and various waste materials to expand the source of feed. Roughage is an indispensable feed for all kinds of livestock and plays an important role in promoting gastrointestinal motility and enhancing digestive power. It is also the main feed for herbivorous livestock in the winter and spring. Fresh herbage, forage crops, and hay and silage made from these ingredients are generally good palatability, high nutritional value, and can be fed directly to livestock. Low quality roughage resources such as straw, clam shells, oyster shells, etc., due to poor palatability, low digestibility, low nutritional value, directly fed to ruminants alone, it is often difficult to achieve the desired feeding effect. In order to obtain better feeding effect, these low-quality roughages are often processed, processed and processed appropriately in production practice.
Recommended diet formula:
Formula 1: 0.5 kg of grass hay or straw, 4 kg of silage corn, and 0.5 kg of concentrate. The formula diet contained 40.60% of dry matter, 4.12% of crude protein, 0.24% of calcium, 0.11% of phosphorus, and 17.97 million joules of metabolizable energy.
Recipe 2: 1 kg of grass hay or straw, 0.5 kg of silage corn, and 0.7 kg of concentrate. The formula diet contained 84.55% dry matter, 7.59% crude protein, 0.6% calcium, 0.26% phosphorus, and 14.38 MJ metabolism.
Feeding sheep in areas with feed processing conditions can use pellet feed. In pellet feeds, straw and hay powder can account for 55% to 60%, and Semenaceae 35% to 40%.
Lamb fattening feed formulation: 62% corn, 12% bran, 8% soybean meal, 12% cottonseed meal, 1.8% stone powder, 1.2% calcium hydrogen phosphate, 1% urea, 1% salt, 1% premix. The formula protein is 18% and the sheep digest energy is 12.94 MJ/kg.
Feeding strength finishing fat formula: the first 20 days: corn 46%, 20% bran, cotton aphid or vegetable meal 30%, stone powder 1%, calcium hydrogen phosphate 1%, salt 1%, premix 1%. The formula protein is 18.5% and the sheep digest energy is 12.78 MJ/kg. Mid-term 20 days: 55% corn, 16% bran, 25% cotton aphid or vegetable meal, 1% stone powder, 1% calcium hydrogen phosphate, 1% salt, 1% premix. The formula protein is 16.8% and the sheep digest energy is 13.00 MJ/kg. 20 days later: 66% corn, 10% bran, 20% cottonseed meal or vegetable meal, 1% stone powder, 1% calcium hydrogen phosphate, 1% salt, 1% premix. The formula protein is 15%, and the sheep digest energy is 13.20 MJ/kg.
For the use of premixes, because the general farms and farmers do not have the conditions for self-distribution, it is recommended to choose regular, reputable manufacturers to purchase.
Scientific daily feeding management
1. Group feeding management. Shepherding sheep should be reared in groups of sheep of different ages, breeds, and body conditions in accordance with the mode of factory production. A special delivery room and a lamb house, a sheep shed, a sheep house, a sheep house, and a diseased sheep isolation house should be established. And with the corresponding feeding and management measures.
2, to strengthen homesickness exercises. Every day, the sheep maintains sufficient exercise to promote metabolism and maintain normal growth and development.
3, breeding density should be reasonable. Oviparous ruminants have a longer period of time to eat forage and ruminants. Therefore, the sheep's pens should have enough slots and space for activities. Each sheep should have 1.5 to 2.5 square meters of activity space.
4. Ensure adequate drinking water. Drink clean water, 2 or 3 times a day, you can also take free drinking water.
5. There must be a transition period for refueling. Change the type of feed, change the diet should be gradually completed in 2 to 3 days, should not change too fast; do not feed wet, mildew, degenerate feed.
Experts solve the disease. (1) Cause: The occurrence of this disease is due to the lack of carotene or vitamin A in the feed of the sheep; improper preparation and processing of the feed, which deteriorates the fatty acid and accelerates the oxidative decomposition of vitamin A substances in the feed, leading to vitamin A deficiency. When the sheep is in a state of protein deficiency, it cannot synthesize enough retinal-binding protein to transport vitamin A. Lack of fat can affect the dissolution and absorption of vitamin A substances in the intestine. Therefore, functional vitamin A deficiency can occur even when vitamin A is sufficient when protein and fat are insufficient. In addition, vitamin A deficiency is most likely to occur secondary to chronic intestinal disease and liver disease. (2) symptoms: The lack of vitamin A in diseased sheep, especially lambs, the earliest symptoms are night blindness, often found in the morning, evening or night light, when the blindness of the sheep is currently entering, collision obstacles, or slow action, cautious; and then Abnormal bone causes compression and deformation of the spinal cord, epithelial cell atrophy, often secondary to sialadenitis, paraocular gonides, nephritis, urolithiasis, etc.; late disease is particularly prominent in the dry eye of lambs, leading to corneal thickening and the formation of clouds shape.
Expert treatment. 1Prevention: a. Strengthen the management of feeds, prevent feed from fever, mildew, and oxidation to ensure that vitamin A is not destroyed. b. Silage or carrots are required in winter feeds, and green hay should be stored in the autumn; cod liver oil should be properly added to long-term fed yellow hay.
2 treatment: a, to the sick lamb oral cod liver oil, 20-30 ml each time; b, with vitamin A, vitamin D injection, intramuscular injection, 2-4 ml each time, once a day; c, added in the diet Green feed and cod liver oil can be quickly cured.
