Feeding and management techniques of meticulous management and protection of benefit mutton sheep in autumn

Raising mutton sheep

As a grass-roots agricultural technology promotion instructor, the main promotion technology of our county this year is mutton sheep breeding. Through practice, I feel that farmers often encounter many problems in practical work, such as breeding technology, epidemic prevention and control, and many other problems need to be solved urgently. Next, I would like to talk about several problems in the feeding and management of mutton sheep in autumn, in order to further improve the efficiency of breeding.

The main work of goat feeding and management in autumn is to do a good job in fattening, breeding and epidemic prevention and control, which plays a key role in goat production and improving economic benefits.

1. Fattening in autumn

Autumn is the golden season for goats to fattening. Fattening in autumn is the key to gain weight and improve economic benefits in winter.

1.1 appropriate extension of grazing time

During this period, all kinds of plants have more seeds and are rich in nutrition, which is an important period to catch fat and gain meat, and it is also the best time for grazing. Pure thatched sheep do not like it, but they can choose vines, thickets and thorn ridges that sheep like. The place where the forage grass is fat and beautiful for grazing, the autumn is crisp and the temperature is suitable, you can go out early and come home late, and try to increase the time for sheep to eat. If there is shelter from the wind and the sun, the sunny slope with better water source is better.

1.2 Night supplementary feeding is the key to fattening.

Because goat foraging can not completely guarantee nutrition, so it is necessary to add concentrate feed in time to promote its fattening. It is best to carry out supplementary feeding at night, and the supplementary feeding time should be about 9 o'clock in the evening, which is not conducive to rest and digestion of sheep. During supplementary feeding, attention should be paid not only to the quantity of feed, but also to the quality of feed. First feed concentrate, put in wheat bran, soybeans, corn and other concentrate, prepare according to 0.2-0.3 kg each, then feed hay or coarse material, or green dry mix, forage should be added less frequently, that is, to maintain the sheep's appetite, do not cause waste, and finally drink water. But also in time to supplement the required minerals and vitamins and other nutrients. Supplement salt, folk also known as light sheep, put salt bricks in the sheep shed or supplement salt 2 to 3 times a week, each time 10 to 15 grams, mix and feed or add to the water to drink.

2. Breeding of sheep in autumn

Sheep can be in estrus in four seasons and can be mated, but autumn is the peak season of estrus for sheep. From mid-August to October every year, a large number of sheep are concentrated in estrus with obvious symptoms, good ovulation and high conception rate. At this time, the delivery period of breeding goats is in winter, and the lambs born have the advantages of large body weight, good physique, low morbidity and rapid weight gain, so it is an excellent season for breeding.

2.1 kinds of ewe management

2.1.1 Lambs were weaned. Ewes during lactation are not in estrus, lambs can be weaned in 60 days, ewes can be in estrus about 20 days after weaning, and weaning can be fed with 150g barley malt artificially isolated or fried.

2.1.2 controlling the fat condition of ewes. Breeding ewes should not be too thin or too fat, which will affect oestrus. In fact, after weaning ewes, more thin, too thin 0.2 kilograms of concentrate per day, should not be given more, feed more fat.

2.1.3 eliminate old sheep. Ewes should be eliminated at the age of 8, and old sheep are not in estrus or irregular estrus for a long time.

2.1.4 use drugs to urge estrus and promote ovulation. With... (which medicine is best written down) but some drugs can only be in estrus but not ovulate, but also in conjunction with other drugs.

2.2 Management of rams during the mating period

2.2.1 reasonable supplementary feeding. In addition to feeding bean cakes, corn and other concentrate, it is also necessary to timely supplement feed with more vitamins such as carrots, forage grass and vegetable leaves, and pay attention to feeding foods rich in minerals such as salt and bone meal. 2 to 3 raw eggs can be added when the task of breeding is large, which can improve semen quality and ensure drinking water twice a day.

2.2.2 strengthen the campaign of breeding rams. Exercise time should be 6 hours per day, in order to ensure the physique and sexual desire of the breeder ram.

2.2.3 reasonable arrangement of mating time and times. Every day to limit the number of mating, three times is better, not excessive mating, to ensure the physical fitness and breeding ability of rams.

(3) epidemic disease prevention and control

Epidemic prevention work in autumn. Immunization should be arranged reasonably according to the local epidemic situation and the immune characteristics of various vaccines. In the first ten days of September, goats can be vaccinated with the quadruple vaccine of "sheep fast epidemic, sudden death of sheep, enterotoxemia, lamb dysentery", and the second half of the month can prevent Streptococcus and sheep pox vaccine and so on.

4. Prevent the occurrence of diseases

Common diseases of goats in autumn, such as gastroenteritis, cold, stomatitis and so on. If we do not pay attention to prevention and timely treatment, it is easy to cause mass occurrence, slow growth and other phenomena, so we should pay attention to observe sheep at any time, early detection and early treatment.

4.1 Prevention and treatment of gastroenteritis. Isolate the sick sheep, put them in a warm and dry place, and use antidiarrheal agents for those who do not stop diarrhea. Take tannic acid protein 2Mel 5 g twice a day for anti-inflammation and sterilization; berberine hydrochloride tablets or sulfamidine tablets for internal administration, or 10 ml of 1% berberine sulfate injection or 10 ml sulfadiazine sodium injection or norfloxacin intramuscular injection. According to 50kg, Codonopsis pilosula 30g, Atractylodes macrocephala 30g, tangerine peel 15g, Fructus Aurantii 15g, Atractylodes macrocephala 15g, Sanguisorba officinalis 15g, Schisandra chinensis 15g, Schisandra chinensis 30g, dried ginger 5g, licorice 25g, Jiao Sanxian 30g each.

4.2 Prevention and treatment of colds. With the sudden change of temperature or sudden rain at the end of autumn, sheep are prone to catch a cold, which is mainly treated by antipyretic, analgesic and wind-cold. Intramuscular injection of Bupleurum, Antongding and other drugs, in order to prevent secondary infection, but also the use of antibiotics, penicillin 1.6 million units, streptomycin 500000 units. Traditional Chinese medicine can be used to make stomach tube guide service according to 50 kg honeysuckle 20g, forsythia 30g, Platycodon grandiflorum 15g, burdock 15g, peppermint 15g, Schizonepeta tenuifolia 15g, almond 15g, trichosanthin 20g, gardenia 15g, licorice 12g.

4.3 Prevention and treatment of stomatitis. When sheep stomatitis occurs, feed soft forage, use less rough fodder, avoid oral injury again, rinse the wound with 0.1% potassium permanganate solution and 20% salt water, and then apply iodine tincture, purple solution, erythromycin ointment, etc. to prevent secondary infection, penicillin 800000 units can be injected, streptomycin 1 million units can be isolated in time, and pens and utensils are disinfected with 10% lime milk or 20% plant ash water. Traditional Chinese medicine can be studied with Qingdai 15g, Coptis chinensis 10g, Phellodendron Phellodendron 10g, peppermint 5g Platycodon grandiflorum 10g catechu 10g borneol 10g and applied to the oral lesions of diseased sheep.

5. Strengthen deworming and epidemic prevention

In the process of raising goats, the common parasitic diseases harmful to goats are trematodes, nematodes, tapeworms, and often show mixed infection, if not prevented and treated, it will seriously affect the growth rate of goats, and even endanger their lives. Therefore, in autumn, goats should be thoroughly dewormed, and ivermectin can be used for deworming. Ivermectin is a broad-spectrum, high-efficiency, low-toxic deworming drug, which can treat and prevent a variety of parasites. It can be injected again a week later, and the deworming effect is better. The common parasites on the body surface of sheep are lice, mites, etc., which can be wiped with 1% trichlorfon solution or pine needle powder, or treated with deworming injection or Chongkexing powder.

In short, farmers should carefully manage and protect goats in the process of breeding, reduce the occurrence of diseases and accidents, improve the survival rate of sheep, and ensure the benefit of breeding.
