Lodge series nutritious licking bricks are rich in mineral trace elements such as "phosphorus, calcium, zinc, magnesium, iron, cobalt, iodine, manganese, selenium, sodium", etc., which are freely supplemented for individual ruminants in the group, and finally achieve the group micro-mineral balance, improve feed conversion rate, solve pica, and bring sustainable health to ruminants.
Autumn is the golden season for ewe breeding every year. It is really a tired but happy day for our sheep farmers. The quality of breeding work directly affects the breeding benefits of the whole year in the coming year.
When is the best time to start mating a little ewe?
Generally, the sexual function of sheep is mature 4~6 months after birth, and the performance of sexual maturity of young rams is: following ewes and climbing across; The performance of little ewes is estrus. If mating is carried out at this time, offspring can be bred. But this is the lamb growth and development of the most vigorous period, if premature mating, not only will affect its growth and development, but also affect the next generation of physical and production performance.
Therefore, the maturity of sexual function does not mean that it is the most suitable age for breeding. In order to prevent random matching of lambs, male and female sheep should be raised and grazed in groups 3 months after birth.
When is it most appropriate for lambs to start breeding?
It is best to determine according to the variety and its own development. Generally speaking, it is most suitable to start breeding at the age of 10 to 12 months after birth. If well-developed purebred sheep weigh 35-40kg and improved sheep 30-35kg, they can be bred!
How many years can the ewe be used?
The service life of breeding sheep is about 7 years, with the strongest fecundity at the age of 3 to 5, the best offspring and the best production efficiency. After the age of 6, it gradually declines until it loses its fertility and productivity.
The service life of male and female sheep is closely related to the feeding management, and the lack of nutrition or excessive nutrition will cause infertility. Ewes are generally 7 to 8 years old to terminate estrus and lose their reproductive ability.
Therefore, in order to extend the useful life of sheep, it should be given reasonable feeding management. Timely elimination of old ewes can improve efficiency.
When is breeding best?
After the ewe is sexually mature, it is best to concentrate on breeding in the estrus season. 3-May and 9-November of each year are the two seasons of sheep breeding. Because the gestation period of sheep (including Saanen dairy goat, Dorper sheep, Small Tail Han sheep, etc.) is about 150 days, if the breeding pregnancy is from September to October, lambing can be given birth in February to March of the following year.
One is to avoid the severe cold and hot weather to produce lambs, ewes are about to enter the period of abundant grass or about to enter the period of grass, the natural environment is extremely favorable for ewes to lactate and ensure the survival of lambs.
Second, the lambs produced in early spring can reach the age of 8 to 9 months in that year, weighing 30 to 35kg, and can be mated from 10 to 12 months.
Third, according to its physiological laws, ewes enter the peak lactation period in the third month after delivery. Lambing in spring and autumn can ensure that sheep eat nutritious grass seeds and tender grass during the peak lactation period, which can improve the milk yield of sheep and increase economic benefits. Lambs eat enough milk and are also conducive to growth and development.
What is hybrid advantage?
Two varieties were used for hybridization. If the Australian white ram is matched with the local Mongolian sheep ewe, the offspring produced have fast growth and development, good body structure, stronger disease resistance than the local sheep, and have the advantages of two parents, and some advantages exceed the parents. This phenomenon is called "hybrid advantage". The breeding of sheep should be selected in a planned way according to the requirements of economic types to avoid inbreeding and increase economic benefits.
Rocky.The series of nutritious licking bricks are rich in mineral trace elements such as "phosphorus, calcium, zinc, magnesium, iron, cobalt, iodine, manganese, selenium, sodium" and so on. They are freely supplemented for individual ruminants in the group, and finally achieve the balance of micro-minerals in the group, improve the feed conversion rate, solve pica, and bring sustainable health to ruminants.
