The Boer Goat is known as the "King of Meat Goats" in the world and is the world's leading goat producing high-quality lean meat. It has the features of large body, well-developed hindquarters, rapid growth and development, good meat quality, high slaughter rate, no seasonal reproduction, strong adaptability, and significant effects of crossbreeding and improving local breed goats. In addition, the Boer goats have excellent plate quality and are made of leather. Since its introduction in 1995, China has become an important breed of hybrids to improve local breed goats.

First, the way of feeding Boer goats

1, grazing

(1) The organization of the flock. Arranging sheep flocks rationally will not only save labor but also facilitate the management of herds. In general, according to the different grazing conditions in different regions, sheep are organized according to the gender and age of the sheep.

Flocks grazing more use of the ground, roadside woodland, embankments, grazing will be subject to certain restrictions, the sheep should not be too large. Breeding ewes and breeding ewes 30-50 as a group, castration 20-40 rams for a group, about 10 rams for a group. The agricultural and pastoral areas and hills and mountains can be determined by visual grazing conditions.

(2) Different seasons of grazing management in the spring As the sheep have passed through a long winter and spring withered season, the sheep are poorly licked, greedy and prone to greed, causing diarrhea, or eating poisonous grass poisoning, or swelling of the grass (turning of the rumen). Therefore, in the spring grazing, we must prevent the sheep from "running green"; second, we must prevent the sheep from "bloating". Grazing in the spring must be tight. At the beginning, old grass slopes or some hay can be placed first and then grazing on Qingcaopo. The grass is tender in spring and the water content is high. In the morning, it can not allow the sheep to eat dewy grass. Otherwise, it can easily cause diarrhea. In addition, in the spring, when the sheep is grazing grass and fresh grass, it is necessary to feed the salt every 5-6 days. It is better to fry the salt when feeding, and add some grated heat, appetizing feed and necessary additives. This can help digestion, increase appetite, and supplement nutrition. At the same time, let the sheep drink at least once a day.

In summer, the weather is characterized by hot, heavy rain, and many mosquitoes. It is necessary to do a good job of preventing heat and cooling. When grazing, attention should be paid to early and late returning. When it is hot in the middle of the day, it is necessary to prevent goats from getting “Zaozizi” and allow the sheep to rest in a ventilated, cool place. If necessary, give proper rest in the middle of grazing. At the same time, we must do a good job in mosquito prevention and deworming. Give more water to the sheep and feed it properly.

The days are warm and fresh in the autumn, and the pastures are abundant, and the grass seeds mature gradually. It should be a season of “going to the sheep”. In the autumn, the flock catches the mutton and maturing season. When grazing, pay attention to put the sheep full and put it well. This is not only for winter fattening, but also for the breeding of safe winter sheep.

In winter, the weather turns cold and the plants begin to wither, with rain, snow and frost. During grazing, care should be taken to prevent cold, keep warm, keep crickets, and keep lambs. Winter grazing is often done in the village before the village and the sheep around the sheep to eat some leaves, hay, sunny and more let the sheep exercise and the sun, pregnant ewes should not turn over the ditch. At the same time, it is necessary to repair sheep sheds and have the idea of ​​"warm circle quintiles."

(3) Matters needing attention when grazing. Grazing staff should carry with them some emergency medical equipment, such as a drop of water to treat heat stroke, and the trocar can be deflated. It is strictly forbidden to throw sheep with stones during grazing to prevent frightening herds. At the same time, attention should be paid to preventing the beasts from invading; do not allow the sheep to eat frozen grass, dew-grass, moldy grass, and do not drink sewage to prevent overeating.

2, feeding rearing

Boer sheep and crossbred sheep are more suitable for feeding, while sheep in farming areas are also fed mainly, and seasonal grazing can be used occasionally. Sheep farms and specialized households have special sheep houses and sports grounds for their sheep, and they have a feeding trough and a sink. Keep the following points in mind when feeding.

(1) Time, quantitative, qualitative, and fixed. Feed the sheep on time so that the sheep will form conditioned reflexes that will facilitate digestion and absorption. According to different sheep, determine the amount of grass fed, the amount of material: to both eat enough, but not wasting; to ensure feed quality and color varieties; conditions should be formulated according to feeding standards with rations; keepers also have to be relatively fixed .

(2) Forage, feed, and drinking water should be cleaned, mildew fodder should not be fed, feed should not carry water, and it is best to drink warm water in winter.

(3) Keep the sheep house clean, dry, cool in winter and cool in summer, and clean the manure frequently.

(4) It is necessary to do a good job of two epidemic preventions and frequent deworming in spring and autumn.

(5) Doing a good job in the sheep farm sanitation and disinfection work. The sheep manure should be used after fermentation.

(6) Increase sheep movements to keep sheep healthy.

Second, the general management of the operating points

1, marking

Labeling is an indispensable link in the breeding work of sheep. It can be easily identified after labeling, and pedigree, growth and development, and growth performance can be recorded. Most labels now use earmarking methods. The ear tag is made of aluminum or plastic and the special steel letters are used to mark the ear tag or write it with a special pen. In addition, the label can also be used ear-cutting method, that is, in the sheep's left and right ears cut a certain number of gaps on behalf of the number, such as the edge of a lack of 3, the lower edge of a lack of 1, the left ear is a single digit, the right ear is ten Number, ear tip and ear count 100.

2, to the angle

Goat horns can prevent injuries during combat. For Boer goats, scissor angle is an important management measure. The method is to stabilize the lamb on the side, touch the base of the corner by hand, cut the base wool, and apply Vaseline around the base of the corner to protect the surrounding skin. The caustic soda (or potassium) stick is then wrapped in one end with paper as a handle, and the other end is rotated and rubbed at the corner bud until a slight amount of bleeding is seen.

3, castration

For lambs born 3-5 days, ligation can be used, ie, the neck of the testicles is tied with a rubbing rubber band. One week later, the testicles were necrotic and detached due to blood vessel obstruction. This method is safer.

For slightly larger rams or adult rams, surgical castration is used. The method is to first disinfect the scrotum with 3% stearine or iodine, and then use one hand to hold the upper part of the scrotum, and the other hand to cut a mouth under the scrotum with a sterile knife, about 1/3 of the length of the scrotum, in order to be able to squeeze out the testis For the degree, cut the testicle together with the spermatic cord and extrude it. Larger rams ligatured sperm cords as necessary to prevent death from excessive bleeding. After the testicles were removed, the wound was coated with iodine and sprinkled with sulfanilamide powder.

4, hoof repair and foot disease prevention

Because of the large size and weight of the Boer sheep, the amount of grazing activity is large, and the growth of the hoof shell is faster. If it is not repaired, it is easy to become deformed, it is difficult to sit down, and it is difficult to walk, which affects its production performance. It is more important to repair hooves for rams, because bad hooves will affect the movement and reduce semen volume and semen quality. The hoof is best cut with scissors for orchard pruning. First cut off the long hoof keratin, and then use a knife to trim the horny skin around the hoof into a level with the bottom of the hoof. Hoofing time should be selected after the rain as well, because the hoof quality is soaked in rain and easy to trim.
