The above-mentioned patent can be adapted to the alpine merino breed that produces high-quality fine wool in alpine and arid regions through cross-breeding, and improves the wool performance. However, due to the vast terrain of our country, all kinds of sheep live in different regions. Due to the restrictions of various factors such as region, breeding site, breed or natural environment, there are cashmere with coarse fineness, low cashmere yield, slow growth and development, and disease resistance. Weaknesses and adaptations.

SUMMARY OF THE INVENTION

The object of the present invention is to overcome the above-mentioned problems existing in the prior art, and to provide a kind of method for cultivating sheep breeds for wool. High adaptability, strong disease resistance and wide application range.

In order to achieve the above objects, the technical solutions adopted in the present invention are as follows.

A method for cultivating sheep for wool, including selection and feeding of breeding sheep;

Sheep selection:

S1. Eliminate newborn sheep and lambs with a weight of <4 Kg and a single twin weight <3Kg, and eliminate cashmere goat lambs with a weight of <3.4 Kg and a single twin weight of <2.8Kg;

S2. Eliminate 10% of the newborn lambs with thin circumferences;

S3. Eliminate 20% of newborn lambs with small abdominal skin area;

S4. Eliminate newborn lambs with superfine wool wool fineness>16μm, fine wool wool fineness>22μm, semi-fine wool wool fineness>40μm, cashmere cashmere fineness>14μm;

S5. Newborn lambs that have not been eliminated form a basic group;

Feeding of sheep:

X1. After feeding enough colostrum of the basic group, 10 ml of goat rumen fluid of adult healthy goat;

X2. Supplement ewes to the base group to suckle, and each ewe sucks 30 to 35 lambs;

X3. The lambs of the basic group are 1-7 days old, and artificial feeding methods are used to feed the lambs;

X4. The lambs of the basic group are 7-28 days old, and the lambs and lactating ewes are separated 4 times a day, and each time is fed for 2 hours;

X5. The lambs in the basic group are 28-59 days old, and the lambs and lactating ewes are separated 3 times a day, and each time is fed for 1 hour;

X6. The lambs in the basic group are 60 days old. The lambs are forced to be weaned once, the lambs are weighed, and the poorly developed lambs are eliminated to form a lamb core group;

X7. Focus on managing the core group of lambs to become breeding sheep.

The newborn lambs include sheep and cashmere goats, the sheep include ultra-fine wool sheep, fine wool sheep and semi-fine wool sheep, and sheep with a weight of less than 4 Kg and a single twin weight of less than 3 Kg are eliminated from the ultra-fine wool, fine wool and semi-fine wool sheep , Eliminate cashmere goats with body weight < 3.4Kg and single twin body weight < 2.8Kg.

Eliminate newborn lambs with superfine wool wool fineness>16μm, fine wool sheep wool fineness>22μm, semi-fine wool wool fineness>40μm, cashmere cashmere fineness>14μm;

X7. Focus on managing the core group of lambs to become breeding sheep.

The wool fineness includes ultra-fine wool sheep fineness, fine wool sheep fineness, semi-fine wool sheep fineness and cashmere goat fineness. Semi-fine wool sheep fineness=36-40μm and cashmere goat fineness=12-14μm newborn lambs.

The abdominal skin area=[(chest circumference-chest width)+(waist circumference-cross width)]×body length÷2.

Taking 240 newborn ultra-fine wool lambs as an example, the first step is to measure the weight of each newborn lamb. There are 65 newborn lambs with a weight of less than 4 Kg, and 75 newborn lambs with a single twin weight of less than 3 Kg. Eliminate these 140 lambs. Only newborn lambs, select the remaining 100 newborn lambs; in the second step, measure the circumference of the tube of each lamb among the 100 newborn lambs, of which 90 have a tube circumference of 6.71-6.73cm, and the tube circumference is 6.68 - There are 10 lambs with a thickness of 6.70 cm, 10 newborn lambs with thin tube circumferences are eliminated, and the remaining 90 lambs are selected; in the third step, the size of the abdominal skin area is measured among the 90 newborn lambs, and 18 lambs with small abdominal skin area are eliminated. For newborn lambs, select the remaining 72 newborn lambs; in the fourth step, measure the fineness of wool on these 72 newborn lambs with fine wool, among which 32 have wool fineness of 14-16 μm, and some have wool fineness > 16 μm 40 sheep, 40 sheep with wool fineness > 16μm were eliminated, and the remaining 32 sheep were selected; the fifth step, these 32 sheep were formed into a basic group, and finally the basic group was managed and fed, and the pipe enclosure was the sheep The horizontal circumference was measured at the upper third of the forearm bone of the left forearm. By selecting lambs with newborn weight, thicker tube circumference, thinner wool, and wider abdominal skin area as the primary backup breeding sheep, the newborn lambs can give birth when they grow up. Produce fine and good quality wool, feed each lamb with colostrum at one time to increase the growth rate of lactating lambs, and then feed adult healthy sheep rumen fluid in one go. Sheep rumen fluid can improve lamb rumen development, thereby improving The feeding of lambs can improve the growth rate and immunity of lambs. When the lambs are 1-7 days old, artificial feeding methods are used to identify the lambs, so that they can taste the taste and eat as soon as possible. It can be fed independently after weaning as soon as possible. By selecting the weight, tube circumference, wool fineness and abdominal skin area of the newborn lamb, individuals with higher wool yield and finer wool can be used as the primary backup breeding sheep, and at the same time, the quality of the newborn lamb is guaranteed. The physical quality of the lambs can make the lambs strong when they grow up; through the reasonable feeding before weaning, the growth and development of the lambs are improved, and the rumen fluid of the adult healthy sheep of the same species is fed to promote the development of the rumen of the lambs, thereby improving the immunity and growth rate of the lambs. Then, the breeding sheep with growth block, strong disease resistance, finer wool, high wool yield and wide application range can be obtained. It can quickly determine whether the individuals are suitable to be reserved for breeding, and identify individuals with high wool yield. After special breeding, they become excellent breeding sheep, which reduces the cost of breeding sheep and lays the foundation for breeding the next generation of high-yield wool.

By eliminating the lighter superfine wool sheep and selecting the lambs with larger physique, but with high wool yield, finer wool and better quality, it not only ensures the physique of the superfine wool sheep, but also ensures the quality of the wool, and reduces the number of species. The cost of the sheep breeding process is wasted.

By selecting the superfine wool sheep with a fineness of 14-16μm to form a basic group, reserve it for key breeding, classify and refine the sheep, and produce cashmere of different fineness according to different needs, which can be used in a wider range. .

By selecting newborn lambs with cashmere goat fineness = 12-14μm to form a basic group, reserve them for key breeding, and classify and refine the sheep, cashmere of different fineness can be produced according to different needs, and the range of use is wider.

The abdominal skin area=[(chest circumference-chest width)+(waist circumference-cross width)]×body length÷2.

In the third step, 90 sheep are listed as columns, measure the chest circumference (C), chest width (E), waist circumference (F), cross width (H), body length (L) of each sheep: C is 30cm, 31cm, 33cm...36cm, E is 10cm, 13cm, 14cm...18cm, F is 20cm, 22cm, 24cm...28cm, H is 14cm, 15cm, 16cm...19cm, L is 100cm, 110cm, 113cm...120cm, obtained by the formula of abdominal skin area (D)=[(C-E)+(F-H)]×L÷2, D 1=[(30-10)+(20-14)]×100÷ 2=1300 , D 2=[(31-13)+(22-15)]×110÷2=1375, D 3=[(33-14)+(24-16)]×114÷2=1539… ...D 90=[(36-18)+(28-19)]×120÷2=1620, where D<1539 means 16 lambs, weed out these 18 lambs, and select the remaining 72 lambs. The actual situation of each lamb's body calculates the abdominal skin area, so that the abdominal skin area is proportional to the lamb's body size, which is convenient to control the development of the abdominal skin area, so that the lamb's growth process is uniform, the posture is correct, and the wool production is higher.

The above-mentioned embodiments only represent specific implementations of the present application, and the descriptions thereof are relatively specific and detailed, but should not be construed as limiting the protection scope of the present application. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the technical solution of the present application, several modifications and improvements can be made, which all belong to the protection scope of the present application.
