Recently, the author has visited some farmers engaged in breeding for a long time and kept a large number of animals in the abnormal situation of slow estrus in spring animals and foxes. The reasons are summarized as follows. 1. The climate is abnormal. The winter and spring temperatures can be described as pre-warming and post-cold. This weather condition is just inconsistent with the conditions of the winter and fox winters and the weather conditions needed during the early spring estrus period. It is advisable to adjust the body's climate in the season to be cold. This will increase the physical transformation of the species and achieve the purpose of body reconstitution. The temperature after entering the middle and late January should be gradually warming, so as to promote Breeds of estrus, complete mating. However, the past facts and the current situation are not satisfactory. The temperature in the harsh winter is much higher than in previous years. The current spring temperature is low day and night, which directly affects the hunting and mating of beasts and foxes. 2. Feed factors. Due to the large number of species of animals kept by farmers in recent years, in order to save time and labor, many farmers have chosen feeds that are universally-priced. This kind of feed is very practical due to the presence of trace substances and various hormones in the growth process of fur animals. It is particularly effective for leather beasts. The fur is bright, the scale is huge, and the road is excellent. However, to be realistic, the feed should be controlled and fed in order to avoid affecting the emotion and mating. At this point, some of the large-scale breeding farms have deep feelings. Feeding homemade corn flour and fish meal, eggs, animal feed, and fox animals are in good condition. The mating is very smooth and is completed very well. 3. Excipients missing. Many farmers abandoned the feeding of vitamins and auxiliary drugs during the winter and early spring breeding periods, causing the estrus to be delayed. Xiao Zhao, a farmer, has a large quail and fox farm on the edge of the county. Each stage of the year is fed with various vitamins and estrus-promoting drugs. However, he did not feel any significant effect. He did not continue to feed during the winter and spring. , abnormal weather conditions and comprehensive factors, the impact is immediately apparent. "All kinds of trace elements and medicines that promote estrus, and foods can not be fed, otherwise it may have a direct impact on heat." Xiao Zhao advice. At present, farmers do not need to worry too much. Over time, the temperature will gradually increase and more and more estrus animals will emerge. However, farmers are required to pay close attention to the estrus progression of each animal species and grasp the timing of mating. You must not miss the best conditions for estrus and mating under such conditions, otherwise you will suffer irreparable losses, especially for beasts such as silver, black fox and colorful fox, because the estrus of these beasts and the time allowed for mating are very high. Short, only a few hours, can be described as fleeting.
