Breeding technique of Boer Goat

Boer goat is one of the most tolerant and adaptable livestock breeds. It can adapt to all kinds of climate zones in South Africa, and the inland climate, tropical and subtropical bushes, semi-deserts and deserts all grow well.

Management at the initial stage of introduction

1. Preparation before introduction: sheep like to be clean, dry and afraid of heat, so the enclosure and sports ground should be thoroughly cleaned before introduction, the enclosure, feeding trough and surrounding environment should be disinfected with 2% caustic soda water or Lysol, and the feeding trough should be cleaned with clean water. The enclosure is required to be well ventilated in summer, moistureproof and shade, and can protect against cold and wind in winter.

2. Feeding and drinking water: the breeder sheep are very tired after long-distance transportation. Let the sheep have a full rest first, do not be frightened, and then drink water after it is stable. Do not give drinking water that is very different from your body temperature for the first time. The water must be clean and fresh. As the sheep are on an empty stomach for a long time, do not feed too much for the first time, you can give high-quality dried grass to 6: 7% full, so that the gastrointestinal function can be fully conditioned, and then gradually give and increase concentrate and free forage.

3. Clear sheep are grouped: after a short rest after feeding, all imported sheep are counted and checked, and grouped according to sex, age, individual size and physical condition. For the thinner sheep, the amount of fine feed and special nursing should be increased appropriately to restore the body condition as soon as possible.

4. Deworming and preventive injection: deworming is carried out in batches according to specific conditions, that is, the structure of sheep, the mating situation of pregnancy and the body condition of sheep are flexibly mastered. The focus of preventive injection is to inoculate triple vaccine, streptococcus vaccine and lamb dysentery vaccine and so on.

5. Observation and treatment: Boer goat has strong disease resistance, and the symptoms are not obvious at the initial stage of the disease. The mental state, feeding, exercise and drinking water of the sheep should be observed carefully. If there is a slight abnormality, it means that the sheep is sick, and the reason should be found in time to give treatment. Newly introduced sheep often find cough, runny nose, slight diarrhea or large pieces of feces, which is a normal phenomenon, which usually lasts only 1-2 days, and should be quarantined and treated in time for a long and serious time.

6. Reducing stress: due to the differences in environmental conditions, feeding methods and feeding levels between introduction and feeding areas, the feeding mode should not be changed at once, but should be transferred gradually so as to reduce the stress response of sheep as much as possible. adapt to the local environment and feeding methods in a short time.

Prenatal preparation

Boer goat lambing preparation, before lambing, the delivery meat sheep house should be cleaned, the walls and floor should be disinfected with 5% lye or 2%-3% laisu, whether spraying the floor or smearing the walls carefully and thoroughly. It should be sterilized for 2 or 3 times during the lambing period. The mutton sheep shed for childbirth should have sufficient area. Try to keep dry and constant temperature during lambing. Mutton sheep are prone to problems when they are wet. Equipment for keeping administrators, troughs and grass racks should be inspected and repaired before lambing. And disinfect it with alkali or lime water. The delivery column is a necessary tool for lambing. The ewe is kept in the pen after giving birth to the lamb, which can not only avoid the interference of other mutton sheep, but also facilitate the ewe to recognize the lamb. Therefore, the delivery column should be prepared or repaired before lambing. In summer and autumn in pastoral areas, Boer goats had better set aside some pastures not far from the mutton sheep pen and try to surround them instead of grazing. The grazing grassland for lambing ewes is suitable for grazing ewes for one and a half months. The grass should be sheltered from the wind and towards the sun. Close to the source of water. Ewes generally do not graze within a few days after delivery, so there should be a sufficient amount of high-quality hay, silage and juicy feed for lambing ewes.

Postpartum management

1. As the delivery period is approaching, we should pay attention to the status of ewes and do a good job of delivery. On the day after the birth of the lamb, remove the mucus around the mouth and nose of the newborn lamb and the meconium of the anus in time, and disinfect the navel with 5% iodine tincture. Be sure to let it eat colostrum to facilitate the excretion of fetal stool. When ewes die or lack milk, try to eat the colostrum of other ewes. Newborn lambs, strong lambs can suck milk, weak lambs, or newborn ewes, the nanny is not strong ewes, need artificial feeding, that is, the ewes are enclosed in the mother's pen, the lambs will suck milk, and the weak lambs should be fed every 1-3 hours, so several times, they will find their own ewes to suck milk. When feeding, ewes often smell the tail of the lamb to identify their own lambs, so when feeding other ewes for reasons such as lack of milk and multiple births, they should paint the lambs with ewe urine to make them recognize the lambs.

2. Lambing should generally be in the lambing room or in a special lambing pen. Within 3-7 days after delivery, the mother lambs live here to ensure that the lambs can eat colostrum and make them compatible. At the same time, attention should be paid not to squeeze the lambs when the ewes rest at night. Ewes can graze outside the house on the 7th day after delivery, and let the ewes return to feed the lambs at noon. When you come back in the evening, you should pay attention to making sure that each lamb can find its own ew. if there are conditions, the best ewes should be fed for 15 to 20 days.

3. Lambs should be trained to eat grass at the age of 15 to 20 days. At the age of half a month, the mixture was supplemented with 50g / d, 100g / d at 1-2 months, 200g / d at 2-3 months, and 250g / d at 3-4 months. The composition of the mixture is beans, bean cake, corn, etc., it is best not to use cottonseed cake; hay to alfalfa, peanut seedlings, willow leaves, etc., hay should be chopped. Feed concentrate first, then coarse feed, and properly add green fodder, at the same time, ensure adequate drinking water, and let the lambs do some activities in the playground every afternoon.

4. The method of weaning lambs is that they must be weaned at the age of 3 to 4 months. One more weaning method is adopted, that is, the mother and offspring are divided into groups, and the ewes are removed after weaning, and managed in groups according to the sex and strength of the lambs.

5. castration and tail amputation at the right time, non-breeding lambs can be castrated at the age of about 4 weeks, and surgery and ligation are often used. Tail amputation can be carried out within two weeks after birth, and the methods of burning and ligation are often used.

6. Strengthening the supplementary feeding of lactating ewes is very beneficial to the growth and development of lambs. Within 8 weeks after birth, lambs mainly rely on breast milk for growth. Ewe supplementary feeding is mainly in the late pregnancy and lactation period, the time is about four months. High quality hay and concentrate should be selected for supplementary feeding. 1.5 kg of hay (alfalfa or wild hay), 1.5 kg of silage and 0.45 kg of concentrate can be fed daily. Within 3 days after lambing, if the ewe is in good health, you can not feed concentrate for the time being, but only high-quality hay to prevent indigestion or mastitis.

7. Do a good job in the hygiene of the enclosure, keep it dry, clean and warm, keep the temperature at 0: 5 ℃, and prevent thieves from blowing. To frequently mattress grass, or dry soil, dry dung, etc., to keep the ground dry, to remove shedding miscellaneous hair, iron wire and other sundries in time, so as not to cause intestinal blockage or perforation and death of lambs. The trough should be clean and hygienic.

The Origin of Boer Goat Generation

A generation of Boer goats

The first generation of Boer goats uses purebred Boer goats to mate with our domestic local goats. The lambs produced are called the hybrid generation of Boer goats, referred to as hybrid one, and their somatotype characteristics are obviously better than those of local goats. The rate of weight gain is significantly higher than that of the mother. In addition, its ears are not as upright as the matrix, but straight or slightly drooping.

Second generation Boer goat

The second generation Boer goat is a lamb produced by mating between the purebred Boer goat and the first generation Boer goat, which is referred to as Za'er. The body shape, weight gain rate and body importance of the second generation Boer goat are obviously better than those of the first generation Boer goat, and its head begins to show reddish features. but some of them do not appear this feature, the most important feature is obvious drooping of both ears and circular shape.

Three generations of Boer goats

The third generation Boer goat is a lamb produced by mating between the purebred Boer goat and the second generation Boer goat, which is referred to as the third generation of Boer goat. The appearance characteristic of the third generation Boer goat is close to that of the purebred goat. The ram can be reserved for breeding, with a red or black head, plump body, upright limbs, warped tail and smooth hair.

Four generations of Boer goats

The fourth-generation Boer goat is a lamb produced by mating between the purebred Boer goat and the third-generation Boer goat, referred to as the third-generation hybrid goat, which is obviously better than the third-generation Boer goat hybrid goat and is close to the purebred Boer goat.

Five generations of Boer goats and six generations of Boer goats were bred by analogy. First of all, remember that if you want to breed a good Boer goat, you must use a purebred ram, and you must not use the same purebred Boer goat to get close to or cross with a purebred ram. It can't be called improved crossbreeding, and you can never breed a good breed of sheep.
