The farm has two pairs of Landrace pigs and a pair of Northeastern pigs as initial breeding pigs. [Read the latest chapter] To expand the pig herd, bringing your own foreign female stock is not enough - it is too much of a waste of precious semen from well-bred boars. A sow can only produce two litters a year, while a boar can breed 20 to 30 sows a year, and artificial insemination can breed nearly a thousand sows a year.
Therefore, he specially collected the Lingao pig, the most representative local breeding pig, as the female parent, and used artificial insemination to quickly expand the population. The local pig farming industry is quite advanced, and every household raises pigs. Unfortunately, the level of raising pigs is so poor that they are all malnourished according to modern animal husbandry standards. Yang Baobao reluctantly bought a dozen sows that were reasonably good for breeding. In addition, more than ten sow piglets were carefully selected and raised to serve as female breeding stock.
Because Xiong Buyou talks about protecting purebred Lingao pigs all day long - every time he talks about Lingao Animal Husbandry Station crossbreeding purebred Lingao pigs, Xiong Buyou is always filled with indignation. Yang Guoguo specially obtained several pigs from farmers for fattening and breeding. It turned out that the Lingao pig was not a pig breed suitable for large-scale production of modern agriculture - its growth period was too long and its weight gain was unheard of. He asked the locals and found out that it takes 24 months to fatten a pig weighing about 200 kilograms before it can be slaughtered. Compared with modern pigs, it is really uneconomical to keep pigs for only one year.
"It's understandable that the Lingao Animal Husbandry Bureau turned all Lingao pigs into hybrid breeds. Otherwise, how could it have been able to satisfy such a large number of exports?"
"You are also turning Lingao pigs into hybrid varieties."
"I still have a few purebreds - I have to keep a few breeding animals of each breed. It's important to keep the original breed."
Most of the rows of newly built pig pens on the pig farm are still empty. Lingao is not very cold in winter, but it is hot and humid in summer, with a lot of rain and typhoons. Therefore, when Yang Guoguo presided over the construction of the farm, he chose a single-slope open pigsty to facilitate ventilation and heat dissipation. Moreover, the materials used in the pigsty are quite sophisticated, and the floors are all smoothed with cement. The entire pigsty strives to be strong, able to withstand strong winds, and has good rainproof performance.
"Summer typhoons are no joke," Yang Baoguo said. "Now greed makes things cheap. If the pig pen collapses and the pigs are crushed to death, there will be losses."
Wu Nanhai noticed that there was a large area of land surrounded by strong bamboo fences near the pig pen. The soil was messy and messy, and there were several black mud ponds.
"This is a stadium for pigs," Yang Baoguo said. "Although we don't raise running pigs, moderate exercise is good for pigs to increase their appetite. The mud pond is also their favorite activity - it can also prevent diseases."
Many plants have been planted around the pig house and the sports field, including windbreak saplings. Pumpkins are planted at the base of the pig house wall. Zucchini are planted on a shelf above the 1U sky fence of the pig house. Not only can it provide shade and cooling for pig pens, but it can also be used to supplement feed.
"This pig's life is really carefree. The surrounding environment is also very hygienic."
"Of course, animals also have psychological stress. Don't think that pigs like dirty and smelly environments. Only when they live a happy life can they get less sick, grow faster, and have good meat quality. Only breeding pigs can be in love."
"Look, this is the purebred Lingao pig." Yang Guogui pointed to a dozen weaned piglets sleeping in the pig pen. "Lingao pigs do taste good, especially the roasted suckling pig." Yang Baogui smacked his tongue. He said, "So raise some alone and let Xiong Buyou make roast suckling pig for you."
Strict housing is implemented here. Yang Guogui told Wu Nanhai that there are 9 types of pig houses here that can adapt to different conditions and ages. Each type of pig pen has a different area and size due to the number of pigs raised, and the equipment structure is also slightly different. In addition, there are breeding rooms specially used for breeding and farrowing houses for sows.
"The so-called scientific pig farming does not necessarily require full-price feed, antibiotics, disinfectants and vaccines - this is a helpless move under modern commercial mass production. For people like us with limited conditions, there are many simple and effective technologies. It can be used, and you can still achieve good results - it is just that the scale and efficiency of breeding are worse. But it is absolutely environmentally friendly."
"Let's just say this pig house is good." Yang Baoguo showed him the floor of the pig house. It was a one-meter-high iron grid floor raised on stone piers.
"This technology is called 'online breeding' - the piglets' feces and urine will leak out and be absorbed by the bedding on the ground. If the net is clean and dry, the piglets will not easily get dysentery. The survival rate will be much higher. It's simple. The principle is not difficult to implement.”
"It's a bit like raising chickens on a high bed and on a flat bed."
"Yes, these technologies are actually similar." Yang Guogui said, "There are also automatic drinking fountains. Last time I went to the Works Energy Commission to ask them to make them, but these people insisted that they didn't have plastic rubber. What kind of plastic rubber did they actually want? Well, just use a lever switch. It doesn't matter if there is a slight leakage. But using an automatic waterer not only makes the pigs' drinking water hygienic, it is also good for the environmental sanitation of the pig pen. The pigs will get sick less often and there is no need for it. Feed them antibiotics all day long..."
Except for a few parts that are made of metal, the traditional drinking fountains made by the Works and Energy Commission Machinery Factory are all made of ceramics and bamboo. Water flows from an elevated reinforced concrete water tank, and thick bamboo pipes serve as water pipes. As long as the pig bends a bamboo lever, the water will flow out of the ceramic jar that holds the water and flow into the drinking tray below. This device has some water leakage, but it is cleaner and less wasteful than pouring water into a stone trough.
"Another example is the feeding of feed. Here we still use the traditional 'thin soup feeding' feeding method. The pigs are fed very thinly. If they are full, it seems to save feed. In fact, too much water affects the digestion of the pigs. On the contrary, It is not easy to get fat. As for pigs, it is not necessary to feed them cooked food. Not only will the nutritional value be damaged, but it is also easy to cause nitrite poisoning. It costs labor and fuel. In addition to swill, general feed can be fed raw. This native method A lot can be done with small improvements.”
Yang Baoguo now focuses on expanding the breeding of civilian pigs in Northeast China. In modern society, except for the use of Northeastern folk pigs as hybrid female parents, meat pigs are basically no longer raised. The reason is that their fat deposition rate is too high and they are pigs that like to grow fat. The demand for pigs in modern society is to get as many pigs as possible. Increase lean meat: In addition to lean pigs, there are also so-called "running pigs", and the simplest ones include things like clenbuterol. So this kind of pig is not popular. But for Chuanchuan Group, in addition to providing meat, pigs are also responsible for supplying fat, an industrial resource.
After pigs, cattle are the largest group of livestock in feedlots. Hainan's main export products in history include cattle. There are many local buffalo and cattle in Lingao. Li District is the main supplier of local cattle. More than a hundred cattle were continuously transported from Lingaoli District Trading and Changhua Fort, which greatly expanded the scale of the cattle farm.
Cattle on cattle farms are mainly used as livestock power. At present, it is not used much in field work, and is mainly used for cargo transportation-oxcart transportation is now becoming the main transportation method across the group. Yang Guoguo not only wants to breed and expand his cattle herd quickly, but also needs to take into account the demand for animal power. The best option is to speed up the import of cattle from Changhua. After being transported, they can be put into service after a little rest and rest. The cattle have low feed requirements and there are no worries about feed supply.
He screened the cattle shipped from various places and found that the buffalo meat was thick and old and was mainly used for livestock farming and pulling carts. Therefore, he controlled the scale of buffalo breeding and mainly raised various types of cattle. Oxen can not only be used to pull carts, but can also be used for meat and skin.
The cows in the cattle farm are resting at this time. It is afternoon and the weather is hot. Several agricultural workers are spraying water around the cowshed to cool down. Because these cattle have to bear heavy road transportation tasks every day, they are particularly well taken care of. Not only do they add concentrate every day, but they also ensure that they are given adequate rest.
“There are so many cattle,” Wu Nanhai said. “It seems that beef is becoming more popular quickly.”
"Actually, the ideal breeding species for us are cattle and sheep - just eat grass. Pigs need a lot of grain. Green fodder can only be used as a supplement. The habit of raising pigs here is to eat rice when fattening, which is too wasteful."
"The purpose of planting sweet potatoes on a large scale is to ensure feed grain. In fact, cattle also need to eat grain. They need to eat corn and so on."
"Traditional cattle raising is simply grass-fed cattle. You can also feed specialized green fodder. Corn-raised cattle can only be done in countries with superior natural conditions like the United States." Yang Guogui sighed. He has a unique affection for North America. clock.
They walked through the cowshed specially used for breeding bulls. The fences here were very thick. The bulls had bad tempers and were big in size and strength. They had to be careful whether they were feeding or handling them. However, the local breeding bull Yang Guigui did not like it, and only a few were raised to maintain the original stock. The local cows that are pregnant now deserve the frozen sperm of several well-bred cattle brought from modern time and space for different purposes.
The breeding cows are bred in the spring. Pregnant cows are raised in separate rooms, and a sign is hung in front of each cow pen with the cow's number, age, date of conception, expected date of delivery, breed and breeding breed.
Seeing Yang Guigui coming over, several cows stretched out their heads, stared at him with pairs of big, gentle and moist eyes, and mooed.
"You see they all know me." Yang Guoguo said jokingly and stroked the neck of one of the cows. "This cow is very valuable. It is pregnant with a black and white cow. We will rely on its children for future milk." "As he said this, he checked the trough to see how the cattle were feeding, and then compared it with the blackboard hanging on the wall to see if the breeder had accurately recorded the feeding status. Yang Baoguo has very strict control over feed feeding, and all fodder, concentrate, and salt are all regularly rationed. ! ~!
