When I first arrived at Zhongning mutton sheep science and technology academy, it was still hot summer. Under the leadership of our tutor, Professor Zhou Yuxiang, we started "close contact" with sheep. Gao CHANGPENG (first from left), a doctoral student of Ningxia University, and team members collected blood from sheep. Photo by Guangming Daily reporter Zhang wenpan / Guangming pictures the first thing to learn is to clean the pens, clean the sheep dung, and trim the wool. It sounds irrelevant to technology, but it is the basic skill of raising sheep. What impresses me most is catching sheep. To trim the wool and immunize the sheep, you must first drive the sheep, that is, drive the sheep to a certain place in the pen, and then enclose them with a fence. But there are always a few "disobedient" sheep, forcing you to catch them. The first time I caught a sheep, I looked at one and rushed up. I saw that I was about to catch it, but it made a 360 degree turn and ran away. Finally, under the guidance of Master Wang, the breeder, I gradually mastered the essentials, and I can grasp them one by one. The breeding of Tan sheep in Ningxia has a long history, and the high efficiency and safety of feed are very important. We focus on this issue to carry out scientific research. Due to the high incidence rate of Tan sheep and the low level of green breeding, developing or screening non resistant feed and feed additives that can enhance the immune function of animals and putting forward a feasible "alternative anti" scheme have become the technical problems to be solved urgently. On the basis of previous research, we are now "tackling key problems" in the system integration research and regional demonstration development of new type of anti tannin products and compound Chinese herbal anti tannin additives, and gradually promote them through production practice and feeding experiments. To raise sheep, you must first pick the sheep. We silently read the book knowledge in our hearts: Tan sheep are medium-sized, male sheep have spiral large horns, and female sheep have no horns or small horns... Combined with Master Wang's explanation, we selected the sheep needed for the experiment and grouped them. When the sheep had it, we designed the diet formula according to the nutrition requirements of meat sheep (NY / t816-2021) and combined with the production practice of Tan sheep, and processed the whole mixed diet in a local feed company. During the breeding experiment, we followed Professor Zhou Yuxiang and the technical director of the feed company to xutao Township and shoushoushui Township in Zhongning County for several times to provide breeding technical services and guidance. Whose sheep is sick, what medicine should be taken, what injections should be given, what ingredients are missing in the feed, how to supplement them, what stress reactions the sheep have and how to regulate them are all within the scope of our service guidance. Seeing that our service is effective and the frowns of the farmers are stretched out, we are happy. It turns out that in the small Academy of science and technology, knowledge, scientific research and practice are so tightly combined! We are looking forward to reaping more achievements and surprises in the small courtyard... (outlook new era)
