Autumn is the golden season for estrus mating of ewes. The proper mating of ewes of the right age is the most effective measure to increase the quaternary birth rate and multi-crop rate.
1 choose to stay in sheep
The use of a litter of male and female rams as a species, to maintain the characteristics of sheep breeds.
2. Pre-spiriting
The ewes of the appropriate age should be fed for a short period of time 1 month before the breeding, and 0.2-0.25 kilograms of supplemental concentrate per day. Only escaping females of the right age have good estrus, normal oestrus, and increased number of ovulations, which can increase the quasi-fetal rate and multiple lambs rate of the ewes.
3. Increase the proportion of ewe in the flock
Generally, the rate of doublings of ewes above the second stage of production is high, so it is necessary to control the proportion of high-yielding ewes in the flock. It is advisable that ewes aged 4-6 years account for 50%-60% of the total number of ewes.
4. Grab the fall
The proper timing of sheep mating is a good time for grabbing autumn fleas. Grasping autumn fleas will increase the number of ovulation of ewes significantly, the ram will have a strong libido, the quality of semen will be better, and the quasi-fetal rate and multiple birth rate will increase. Empathy, ovulation and more.
5. Timely breeding
Each time the estrus duration of the sheep is 24-40 hours, and the ovulation time is 30-34 hours after the beginning of estrus. Therefore, the timely breeding time should be 12-25 hours after the estrus. Older ewes have short estrus duration and should be bred early after estrus. Young ewes have a longer estrus time, and breeding time should be later.
6. Implement the compound
Usually within one estrus period, fertilization can be performed once the animals are bred. However, in order to increase the quasi-fetal rate and multi-crop rate, two breedings may be performed in the middle and late stages of the estrus estrus, or 2-3 breeding rams may be used each at one time during one estrus period. If it is artificial insemination, the effect is even better, which can significantly increase the rate of quasi-fetal and multi-rabbit.
Vitamins are organic compounds and vital nutrients that an organism requires in limited amounts. An organic chemical compound (or related set of compounds) is called a vitamin when the organism cannot synthesize the compound in sufficient quantities, and it must be obtained through the diet.
Your body needs them to work properly, so you grow and develop just like you should. They are essential for the normal growth and development of a multicellular organism. Once growth and development are completed, vitamins remain essential nutrients for the healthy maintenance of the cells, tissues, and organs that make up a multicellular organism; they also enable a multicellular life form to efficiently use chemical energy provided by food it eats, and to help process the proteins, carbohydrates, and fats required for respiration.
