From February to March 15 each year, it is a mating period for the species. In general, species estrus reached the peak of estrus in late February and mating began. However, this year's situation was somewhat abnormal. Whether it was in the main support areas of Tangshan and Qinhuangdao in our province or in the non-primary areas in Xingtai and Quzhou, the number of estrus was small by the end of February, especially The newly-found species and estrus were very few, making many farmers depressed or panicked. Some farmers in the field even had the idea of ​​abandoning mating and breeding.
In fact, the feelings of the farmers can understand that the basis for the special income is breeding, and it is impossible to mate without estrus, which means the failure of breeding. However, all things are constantly evolving and the scorpion's estrus is no exception. Due to abnormal winter and spring weather, the average temperature is much lower than in previous years, and the key to promoting the estrus return is the timely temperature, which causes the lag of lice in heat, which is the main external cause; secondly, it is due to the fur market in the previous year. In terms of economy, the general quality of seedlings kept by farmers is not high, resulting in a low “congenital†physical quality of the produced Aberdeen. One factor is that in recent years, in order to pursue short-term benefits, some farmers have blindly fed various types of additives with high levels of hormones, resulting in changes in the physiological systems of the lice, and the occurrence of estrus in the estrus is not obvious or estrus.
In view of the above situation, farmers need not worry too much. With the gradual warming of the weather, most species of geese are able to estrus and can mate, but the time will be slightly delayed, as long as the mating is successful, the farrowing and its subsequent growth will not affected. At the same time, in order to promote estrus, farmers can increase the amount of feed to the species (pre-pregnancy and timely removal), add 15 grams of feed per day, supplemental dosage of vitamin E pills, one pill per meal, and feed some Green onions For foods like this, it was changed from feeding the past to feeding twice a day. On this basis, the measures for warming and heat preservation should be strengthened. The non-estrus species should be placed in sunny sunlit shelters. After the nests and on both sides and above, try to cover them with straw or cotton quilts to increase the temperature of the housing. , promote its estrus. In order to create a comfortable estrus environment for the species, the farmers should not frequently try and check the situation, so as to avoid the opposite effect.
The last thing to note is that according to the current weather trend, the deadline for this year's mating must be postponed. Specifically, it should be pushed back 10 days in the normal years, that is, around March 25, so farmers need to Reasonably arrange for the species to complete mating.
