How much is an ewe now? How to improve the reproduction rate?

Sheep is not only one of the twelve signs of the Chinese zodiac in China, but also one of the livestock of human beings, which can provide cats, milk and meat for human beings, so the scope of breeding is still very wide. How much is the ewe now? How to improve the reproduction rate of ewes?

I. introduction of ewes

1. Selection of ewes

(1) the quality of ewes directly affects the quality of lambs in the later stage, so the selection should be made according to their own actual situation and local environment. If it is captive, choose sheep with fast growth, strong fecundity and suitable for captivity. For example, Hu sheep, small tail Han sheep and du Han hybrid sheep; if there are conditions for raising sheep, you can choose Boer goat, Bo hybrid goat or other goat breeds.

(2) generally speaking, the reproduction rate of ewes of the same breed will be different, so after selection, it is OK to leave high-yield ewes and eliminate low-yield ewes.

(3) when selecting ewes, we must choose ewes with uniform head size, slender neck, long body and large skeleton, especially wide hips and well-developed breasts, so that ewes are more conducive to reproduction; and healthy young ewes are the best choice. healthy breeding has a shiny coat, fat feeling and reaction speed.

two。 Judgement of pregnancy in ewes

The main results are as follows: (1) ewes do not have estrus in 20-30 days after mating, and there is no vaginal discharge, and the increase of food intake, body fat and abdominal circumference with the change of time means that they are pregnant.

(2) the ewe showed gentle temperament and cautious action after pregnancy, and the lack of sexual desire for the ram and not accepting the climb of the ram also showed that she was pregnant.

(3) after pregnancy, the vaginal mucosa of the ewe will become pale, and after opening it with the cavity opener, it will change from white to red in a short time, from which it can be judged that she is pregnant.

How much is the ewe now?

Generally different breeds, quality, origin and other ewe prices are not the same, the following is a brief introduction.

1. The price of purebred Boer goats in Jiaxiang County, Shandong Province is 400 yuan per goat with a weight of 25 kg, a body length of 150 cm and a chest circumference of 35 cm.

two。 The price of Nubian black goat in Linyi, Shandong Province: 900 yuan for 10 or less, 750 yuan for 10-30, and 600 for more than 60.

3. The price of Shandong Jiaxiang ewes with 136 cm body length, 30 kg weight and 62 cm chest circumference: 560 yuan for 10-19 ewes, 530 yuan for 20-29 ewes, and 500 yuan for more than 30 ewes.

The above prices can only be used as a reference, the actual price should be based on the local market price.

Third, how to improve the ewe reproduction rate?

The reproduction rate of ewes affects the benefit of the farm, so it is particularly important to use it to improve the reproduction rate.

1. Choose multi-lamb rams and ewes to keep seed.

Double lambs or multiple lambs are hereditary, and the previous generation of rams and ewes are preferably selected from the reserve flock of more than one twin lamb. These rams and ewes with good genetic basis are reserved for breeding, which can give full play to their genetic potential and increase the probability of multiple lambs in ewes.

two。 Ensure adequate nutrition for rams and ewes

Male sheep maintain strong sexual desire, and there are a large number of sperm, strong motility and high fertilization ability in semen during mating. Strengthening ewe nutrition is an effective measure to improve ewe reproduction rate. When the ewe is strong, the fetus develops well, the postpartum milk is sufficient, the birth weight of the lamb is large, and the survival rate is high. Therefore, the fatter the ewe is, the heavier the lamb is, and the higher the litter rate is.

3. Carry out twice mating

When ewes are in estrus, double insemination or double insemination are carried out to increase the chances of fertilization. Commonly used methods: ewes confirmed estrus, insemination in 12 and 24 hours after each insemination, generally two insemination interval of 10-12 hours.

4. Increase the proportion of young and middle-aged ewes in the flock

The fecundity of young ewes and old and weak ewes is not as good as that of adult ewes. In the life of ewes, the reproduction rate of ewes at the age of 3-4 years is the highest, and the breeding life is generally 8 years, so it is necessary to properly supplement young ewes and increase the proportion of ewes aged 3-4 years in the flock, so as to find and eliminate old, weak or low fecundity ewes in time.

In addition, shortening the breastfeeding time of ewes can also promote ewes to have early estrus and achieve productivity in one year. The above is all the content that the editor of Tuliu.com wants to introduce to you. We must pay attention to the above points when buying ewes.
