Start a discussion to clarify the misunderstanding of the hierarchical division of feed effective energy

To discuss and clarify the understanding. The term "staying along" is usually used in textbooks and journals to divide the effectiveness of feed energy in animal energy nutrition. The unabsorbed digestive tract gas energy (methane energy) belongs to the digestive energy level, and the unabsorbed rumen fermentation heat production belongs to the metabolic energy level. This is obviously wrong! The reason is that the scheme of laboratory research and analysis is regarded as the attribution of the level of feed energy in animals. In addition, the maintenance is not all from the net energy, especially the cold environment maintenance heat source, fermentation heat production and heat consumption will contribute. This also gives a good explanation for the high efficiency of net maintenance! You are welcome to put forward your own views after reading it.

Registration-support that "not all the energy used for maintenance comes from net energy"-- for such a theory, people like Mr. Han, we only have to learn. It is enough to understand the direction of feed energy now, and there is nothing else to ask for-- the picture is very clear and good-- after what the old man said, I found out that this is really the case. Some basic questions are actually not really understood for a long time, thank you, sir! After studying animal husbandry for so many years, I only know today that what is not in the textbook must be the truth! There are still a lot of things to carefully consider and consider! Haha, learn with your heart and with your eyes It's a little different-often-- hehe. Download it and have a look at it!-- in fact, what is written in the textbook may not be entirely correct. Those who talk about popular science technology on CCTV may not understand the technology. The author has also found that in several places, such as the brooding temperature of laying hens, the author has compared the results of more than 60,000 brooding results. The survival rate and egg laying rate of low-temperature method are much higher than that of high-temperature method. It's not only a problem of saving fuel!-- it's just that there are a lot of things that people don't seem to want to publish. I'm just lazy. I didn't write an article to publish in public. This is a publication!-- the truth is often in the hands of a small number of people-- we have gained a lot today, and we are aware that knowledge should be learned and used, and we should look at things in a correct way.
