According to the past years of the breeding process, in February, the captive bred larvae will enter estrus and enter the mating period. However, there are some exceptions this year. Many crickets have no estrus symptoms. What is the reason?
First, the body condition adjustment is not in place. Since winter and spring this year, the temperature in our province has generally been higher than in previous years, and once the species has not been adjusted properly, bodily function will not meet the requirement of heat, that is, physiological characteristics can not receive estrus instructions, and naturally it can not be normal heat.
If farmers have certain experience, they should know that from feed supply to drug assistance, they need to take multiple measures and vigorously exercise their planting status as soon as possible. After all, the estrus’s estrus period is only once a year, and only annually. Before March 15th, the number of estrus days was about 3 days. Otherwise, even if the estrus occurred later, due to physical and climatic reasons, it could not be mated and conceived. Reduced and reduced feed, estrus drugs should follow, here is not a hormone-like drugs, but vitamin E and other auxiliary drugs. If there is no breeding experience, measures cannot be taken indiscriminately to reduce the amount of feed by a small amount, and a little of the drug will prevent it from becoming counterproductive.
Second, feed due to improper feed. Most farmers now feed their full-priced mixed feed. The feed produced by this factory is convenient to feed, and the biggest benefit is that it grows fast and is not susceptible to disease. However, this kind of feed has added various kinds of disease-resistant and disease-preventing medicines. For long-term consumption, it will definitely damage the function of the gardenia itself. This is not a problem for the skin-skinned pods harvested during the year, but for the species Big difference. In the previous year, the author had done a household survey. Feeding the breeding clams reared by breeders with feed, the estrus rate and pregnancy rate can reach 95%, and only 80% of feeds are fed with full-priced feed.
The author suggests that as long as the animals are kept, starting from the nest, they should feed their own feed in order to facilitate long-term culture and population safety. Of course, there is no good remedy for feeding estrus seeds that are not fed on full-priced feeds.
Third, the kind of self-cause. Some farmers have grown their own breeds, and the preserved species have also been preserved by their own families. Therefore, as long as they think that they are big and their skin color is good, they will be determined to be breeding and important breeding. In fact, there are relatively strict standards for the retention and determination of species, and the defamation of the genitals, the attachments that have defects in their internal organs, or their inability to mate at all, are obviously not kept as species. Followed by a species of eel was frightened in the breeding process, but the farmers do not know, at the time, due to over-frightened breeders have basically lost the estrus. For these species, it should be determined as a skin coat. It is best to take skin when peeling skin.
