At this time, Wang Guisheng saw Zhuo Yan clearly, and also saw Chu Xingchen standing beside her clearly, she frowned,

"I know you're Zhuo Han's sister, but even if you want to protect your brother, you can't distort the facts! Tell me what the cow shouldn't have eaten? ”

Zhuo Yan was not ambiguous, she rolled up her shirt sleeves, squatted down and opened the cow's mouth to look at it, and said with certainty, "This cow became like this by eating raw corn on the cob!" My brother knows that cows can't eat raw corn, and he will never give raw corn to cows, who fed raw corn to cows yesterday? ”

It's the beginning of September, isn't it the season when the corn is ripe for the market? However, this thing is not within the scope of the school's feed, so if the cattle eat raw corn, they must be fed by these students.

After listening to Zhuo Yan's words, the students who were watching next to him once again started to discuss, Liu Zhiqiang, who was in the same dormitory as Zhuo Han, glanced at Zhuo Yan, and was the first to stand up, he pointed to Wang Guisheng and said, "Yesterday afternoon, I saw you carrying a net of raw corn back to the dormitory, did you give the cow raw corn?" ”

Wang Guisheng clasped his hands to his chest and snorted proudly, "It's true that I gave the cow raw corn, but you said that the cow would get sick if it eats raw corn, what kind of theory do you have?" Corn is much more nutritious than feed, is it wrong for me to feed corn to my cattle? ”

Wang Guisheng's words represented the thoughts of most of the students present, "Yes, what Wang said is also true, raw corn is more nutritious than feed!" ”

"It's okay for people to eat corn, but how can there be problems for cows to eat corn? I think this girl is exaggerating! ”

"Didn't you hear Wang Guisheng say that she is Zhuo Han's sister? will definitely help Zhuo Han speak! ”

Public opinion was sideways, and no one at the scene supported Zhuo Yan.

"You're just a student at the school, and you don't have any experience raising livestock before, so why do you assume that cows can eat raw corn?" Chu Xingchen stood up and spoke, he had an extraordinary bearing, and what he said was also very reasonable, and none of the students present dared to refute him.

Wang Guisheng peeked at Chu Xingchen and muttered in his mouth, "Then it can't be said that this cow is sick, just eaten from corn?" You don't have any proof, do you? And this cow is in Zhuo Han's hands, so Zhuo Han has to pay for it! ”

Zhuo Yan clapped his hands and looked at Wang Guisheng and sneered, "The cow eats all by rumination, and what it eats for the first time is not chewed, this is common sense, you can't not know, right?" ”

Even in the Animal Husbandry College, before they have time to teach everyone the anatomy of cattle, rumination should be common knowledge, and it will be mentioned in the nature textbooks for elementary school students.

As a herbivore, cattle have a very special way of digesting, because they have to consume a lot of food, so they eat quickly and swallow the forage without chewing.

When it is time to rest, the cow will return this half-digested forage from the rumen to the mouth for chewing.

So after listening to Zhuo Yan's words, Wang Guisheng felt that she was insulting herself as a college student, and her face turned red with anger, "Who doesn't know rumination, I have already learned!" ”

"Oh......" Zhuo Yan deliberately dragged out his voice, "It turns out that you already knew, I don't know what you think you don't know!" ”

Just when Wang Guisheng raised his eyebrows and wanted to refute again, Zhuo Yan also sank his face, "Since you know this common sense, then you deliberately fed corn cobs to the cow, you want to harm the cow!" ”
