After a night of silence, Zhou Yang was woken up by the whistle of work in the village early the next morning.
Opening his eyes, he saw Li Youwei and Bao'er still sleeping soundly. Zhou Yang immediately got up to wash and cook.
Perhaps it was because they were newlyweds. Last night, after Bao'er fell asleep, the couple couldn't help but play passionate games. They were tired but satisfied.
After taking a casual bite, Zhou Yang went out.
He did not go to the brigade headquarters, but went to the methane digester first.
It had been three days since the last test, and he needed to see if the water level in the digester had dropped.
When he came here, Zhou Yang saw a few people standing beside the pig farm from a distance.
After taking a closer look, I found that it was Qin Xueyizheng and Yan Gengdong, and there was a kid standing next to them. Who was it if it wasn't Yan Wenhui!
I don’t know what these people are talking about.
The two were chatting enthusiastically and did not see Zhou Yang.
On the contrary, it was Yan Wenhui, the kid with sharp eyes, who saw someone coming first and reminded his father.
Yan Gengdong and Qin Xueyi immediately stopped talking, and then turned their attention to Zhou Yang.
Zhou Yang immediately walked over and greeted, "Are you two so early?"
Yan Gengdong smiled and said, "These little piggies keep humming and chirping at this time every day, and they can't sleep even if they want to!"
Qin Xueyi said: "The piglets are more active in the morning. If you look at them at this time, you will find that there is something wrong with that pig!"
"What's going on? Are any of the little piggies sick?" Zhou Yang asked immediately.
"Currently, it looks like he is growing well and he is not sick!" Qin Xueyi replied.
"That's good!"
Qin Xueyi said again: "It's really strange. The biggest shortcoming of Landrace pigs is their weak resistance to disease. They are far less resistant than our local black pigs. Especially when the piglets leave the college's breeding farm, they die of disease." The rate is usually around 25%.”
"And when these piglets arrived, they hung around in the car for five or six hours on a hot day. We were all worried about whether the mortality rate would surge."
"But I didn't expect that when these little piglets came to your place, not one of them died of illness. It's amazing!"
Yan Gengdong smiled and said: "That's because the treatment in Babaoliang Village is good and the piglets receive better care, so they don't get sick!"
Qin Xueyi shook his head and said: "It has nothing to do with this. No matter where these piglets are sent, the members will treat them as ancestors. Who will not raise them well, but they will get sick!"
"What's the reason? Did I eat well or something happened?" Yan Gengdong said again.
"Yes, Lao Geng, what you said is on point. I have observed over the past few days that the problem should be the feed you feed!" Qin Xueyi said.
Zhou Yang smiled and said, "Yes, the feed we feed is fermented feed. Compared with ordinary feed, it is not only easier to absorb, but also more nutritious."
"If used together with bone meal, the effect will be better, so the piglets' ability to resist disease will be significantly improved."
Qin Xueyi nodded and said: "Although I cannot analyze the proportions of various nutrients in your feed due to lack of instruments, but judging from the current situation, this feed is indeed very suitable for Landrace pigs!"
"If you only feed this kind of feed, you can really raise piglets to more than 200 kilograms. That will be a huge breakthrough for our pig breeding in Saibei Province, and even the entire country."
Zhou Yang nodded and said: "There are many benefits of fermented feed, you can study it slowly, and the team's feed factory and bone meal factory are open to you all day long, you can also see how to produce feed!"
"Is this...is this really okay? Aren't you afraid that I will leak out the method of making this kind of feed?" Qin Xueyi said in surprise.
"Haha, the situation is too small. If it's leaked, let it be leaked. What's the point?" Zhou Yang said.
"Actually, if possible, you can set up a feed factory based on this formula, and you can definitely make a lot of money!" Qin Xueyi said.
"Feed mills can indeed make money, but compared to promoting Landrace pigs, changing the dietary structure of the Chinese people, and improving people's living standards, which one do you think is more important?"
Zhou Yang sees the role of biological feed more clearly than anyone else. This kind of feed can almost be said to be made for Landrace pigs. With the blessing of biological feed, Landrace pigs will definitely be promoted on a large scale in a very short period of time.
By then, with the size and growth advantages of Landrace pigs, the scale of domestic pig farming will inevitably surge, and all citizens will benefit by then.
Therefore, Zhou Yang never thought of monopolizing this kind of feed from the beginning. Even if Qin Xueyi and others were not available, he would teach this method to other members of the production team.
Upon hearing Zhou Yang's words, both Qin Xueyi and Yan Gengdong were greatly shocked.
The value of biological feed is becoming more and more prominent. It is completely conceivable that once the feed is sold according to this formula, it will be enough for the entire Babao Liang brigade to make a lot of money.
But Zhou Yang did not do this. Instead, he cared about the people across the country and was willing to publish this formula. This kind of mind is admirable.
"Comrade Zhou Yang, on behalf of the College of Agriculture and Animal Husbandry and all farmers, thank you..."
Zhou Yang smiled and said, "Stop representing this or that. As long as you stay here peacefully for five years and teach these people the real pig-raising techniques, that will be the best thank you to me!"
"Don't worry, I will keep my promise!" Qin Xueyi said.
Zhou Yang pointed to the biogas pool not far away and said: "Let's see how the biogas pool is doing. If possible, we can add materials for fermentation as soon as possible!"
"OK!"
Soon three adults and one child arrived at the biogas pool. Zhou Yang carefully opened the sealed lid, and then carefully observed the water level left on the inner wall of the pool a few days ago.
He was pleased to find that the water level did not drop significantly, which proved that the sealing of the two pools was very good and fully satisfactory for use.
At that moment, Zhou Yang personally opened the discharging room and drained all the water inside.
Then he entered the fermentation room again and checked the inner wall of the biogas tank. No signs of cement falling off were found.
Zhou Yang knows that these two biogas digesters can be used!
At this time, the rapid footsteps and various laughter of the members came from outside the pig farm.
Apparently the brigade headquarters has assigned tasks, and the members have come to work.
Zhou Yang immediately shouted and called several young men and women to come over. He was going to feed the biogas tank.
Biogas is a mixed gas produced by microbial fermentation of organic matter in an anaerobic environment under certain conditions of temperature, humidity, and pH.
Therefore, there are three main conditions for biogas digesters to produce biogas. One is sufficient fermentation raw materials, the second is suitable temperature, and the third is microbial bacteria.
Zhou Yang had already collected the fermentation raw materials needed for biogas digesters a few days ago. This stuff is also relatively common. Human feces, pig manure, chicken manure, and cow manure can all be used as raw materials for biogas fermentation.
However, for a newly built biogas digester, it is best to use pig manure when starting the initial feed fermentation. If pig manure is not available, chicken manure can also be used. It’s just that dry chicken manure must be retting for about 10 days before it can be used, otherwise it will not be suitable for fermentation.
In addition to fermentation raw materials, there is also an inoculum, that is, fermentation bacteria.
It is best to use biogas slurry and biogas residue that have been used for normal gas production, but this is obviously not available in the village, but fortunately, it can be replaced by river pond sludge or sediment at the bottom of old manure tanks.
Among these things, the content of biogas fermentation microorganisms is very high, which is a good inoculum.
At that moment, Zhou Yang asked these members to get pig manure and river sludge, and then began to put it into the biogas tank in proportion.
After injecting appropriate amounts of clean water, Zhou Yang closed the lid of the biogas tank again and waited for the fermentation raw materials in the biogas tank to ferment.
As long as air pressure is generated inside, it means that gas has been produced, and then the next stage of power generation test can be carried out.
