Second, according to the relationship between the various levels of the selected Liaoning cashmere goat Liaoning cashmere goats, the following relationships between the various traits. The larger the body size and the higher the body weight, the stronger the food intake and viability, and the faster the growth and development. The longer and dense the velveteen fibers, the thinner the wool, and the higher the cashmere yield, and vice versa. In the high age (referring to 3-5 years old), the well-publicized male and female sheep have strong reproductive ability. The male and female ewes in their breeding and old age have poor reproductive ability. Malnutrition and reproductive defects will affect the reproductive function of the sheep.
In the mid-late stage of the embryo, the velvet pouch begins to develop, and the lamb is weaned at 4 months of age. The velveteen sac has been developed to more than 90%. There is a positive relationship between the cashmere production of Liaoning cashmere goats at the age of 1, 2 and 3 years. The production of cashmere at the age of 1 is high, the production of cashmere at the age of 2-3 is high, and the production of cashmere at the age of 2 is high. At the age of the year, the production of cashmere is also high.
Third, according to the pedigree selected sheep breed a sheep, their grandparents, parents, good cashmere performance or their compatriots, half brothers and sisters of the cashmere performance is good, then its own cashmere production performance is also likely to be good. If the yield of their offspring is relatively high, then basically it can be inferred that the sheep have good cashmere performance and genetic stability. The lambing performance of Liaoning Cashmere goats also has such a regularity. In the selection of Liaoning cashmere goat individuals, it is necessary to carefully review the spectrum in order to avoid the decrease in cashmere production, physical decline, stillbirths, teratogenicity, and weak births caused by inbreeding. In production, due to the frequent transfer of sheep between users and users, it often results in the purchase of rams as the descendants of the last ewes purchased, resulting in child mothers; the rams purchased are the fathers of the ewes they purchase. Fathers and daughters; rams and ewes purchased for their parents, that is, brothers and sisters, etc.
Fourth, at the appropriate timing, the cashmere fiber of Liaoning Cashmere Goat Liaoning Cashmere Goat is not balanced growth throughout the year, but basically began to grow slowly from late June, then gradually accelerated, reaching the peak of growth from August to October. Afterwards, it gradually slowed down, and in late August and November it was a period of vigorous growth. At the beginning of February of the following year, growth basically ceased, and in the middle of March to April, the velvet fiber began to separate from the skin (floating), and combing began in the middle of April to early May. Therefore, when selecting sheep, it is more accurate to observe the cashmere production from the floating period to the combing, and it is easy to observe. In September-December, although the production of cashmere was also observed, the accuracy was relatively low. After combing, for people with less experience, the level of cashmere production could not be discerned with the naked eye.
Fifth, to ensure that there is no hidden danger of breeding sheep before buying sheep, to investigate the local epidemic and vaccine injection and deworming, etc., not in the epidemic area to buy sheep, the purchase of sheep must pass the local inspection agency inspection qualified before purchase Yun. After arriving at the destination, they must observe and observe the animals for a certain period of time after the purchase of the breeding sheep. After determining that there is no outbreak, they will be reared in groups.
Sixth, according to local conditions, the amount of force, fully and effectively use the purchase of sheep capital Liaoning cashmere goats in its origin Liaodong Peninsula has a huge group, its individual production of cashmere from 200-300 grams to more than 1,000 grams, the price also from the few From a hundred dollars to several thousand dollars, the difference is great. This requires the user to act according to the local actual and personal funds, and to use the sheep capital appropriately and effectively. When the user is well-funded, superior in feeding conditions, and strong in technical strength, it is possible to purchase high quality medium-sized breeding ewes for group selection, select high-quality rams for breeding, and improve breeding from generation to generation, selling sheep and cashmere for sale. . On the contrary, the selected criteria should be appropriately increased, selling cashmere, vegetable sheep and expanding the group to increase income. When used to improve local cashmere goat breeds, individuals who produce more than 300 grams of cashmere per local breed should be selected to receive significant improvement. When the original population has high production performance and the phenotype is relatively uniform, genetically stable special-grade male and female ewes should be selected to further improve the production performance of the population. As long as it is practical and the method is appropriate, the raising of Liaoning Cashmere goats will certainly achieve considerable economic benefits. The user shall comprehensively evaluate the breeding sheep according to the direction and focus of the election so as to achieve the purpose of purchasing sheep properly.
