Methods of raising pigs

Adopting scientific feeding methods for pigs can make rational use of feed, improve feed conversion rate, and make pigs get more meat and get rid of it quickly. The following are the pig-raising methods I have carefully arranged for you. Let's have a look.

Methods of raising pigs

1, shell requirements. Generally, the pigsty is required to face south, so that the shed has good lighting and is conducive to fermentation; And well ventilated, not smelly, no mosquitoes and flies. You can also use a plastic shed, which has good lighting and warmth in winter, so that pigs can safely overwinter; In summer, put down the sunshade film and shake up the skirt film around it, which can ventilate and cool down.

2. Make a bed. A cement mud pond with a depth of about 1 m can be built underground.

3. Preparation of filler. The padding is mainly sawdust, accounting for 90%, because it is soft and can absorb water, and 10% is soil and a small amount of salt. The soil requirement is clean soil without chemical fertilizers and pesticides, because there are many microorganisms in it; Coarse salt should be used as salt, which is beneficial to the decomposition of sawdust.

4. Go to bed for fermentation. Mix the strains and padding evenly, then go to bed, the thickness of padding is 80-90 cm, and ferment for 4? In five days, you can enter the pig.

Matters needing attention

1, pigs should be thoroughly cleared of parasites in advance.

2. Spray nutrient solution once a month to maintain the bacterial bed. Nutrient solution is a specially cultivated active agent. Mixing with water at the ratio of 1 300 and spraying on the bed surface can improve the vitality of soil microorganisms and accelerate the degradation and digestion of excreta.

3, the surface of the bacterial bed should not be too dry, it should be kept loose, and dust should not be allowed to rise, otherwise pigs are prone to respiratory diseases.

4. When it is found that there is a lot of pig manure accumulation, it should be spread evenly to facilitate degradation.

5. Pay attention to the feeding density. If there are too many pigs per unit area, the fermentation state of the bed will be reduced, and pig manure cannot be degraded and digested quickly. Generally, each pig covers an area of 1.2 ~ 1.5 square meters.

superiority

1, saving effort. Because there is no need to clean up the feces, if a person can raise 500 heads, this method can raise 1000 heads, saving 50% of the labor force.

2. Save the summary. Because feces provide nutrients for fungi, fungi continue to multiply and form hyphae. Protein content of these hyphae is very high, and they are delicious food for pigs. Eating them can save 20%-30% of feed.

3. Save medical expenses. After pigs eat this bacterium, it can not only help digestion, but also improve immunity, strengthen physique, avoid getting sick and save a lot of medical expenses.

4. Save water. Conventional pigs need a lot of water to wash, but this method only needs to meet the drinking of pigs, which can save 90% water.

In addition, disposable padding can be used for a long time, generally 3? Five years, if well maintained, some can be as long as 10? In 20 years, the replacement padding is high-quality organic fertilizer.

Key points of raising pigs

1. Feed raw and cooked. According to the characteristics of feed types, it is decided to adopt raw feeding or cooked feeding. The principle should be to reduce the loss of feed nutrition, improve the utilization rate and prevent poisoning and diseases. Concentrate and juicy feed such as leguminous seeds, rapeseed cakes, cottonseed cakes, potatoes and sweet potatoes should contain toxic substances. Hello, prevent poisoning. Swill contains all kinds of unknown substances, so it should be cooked and fed. Corn, wheat, sorghum and all kinds of green feed should be eaten raw.

2. Coarse feeding and fine feeding. Lean feed has high water content, fast gastric emptying and little stimulation to the stomach, which leads to decreased secretion of digestive juice and reduced digestion and absorption of feed. So pigs should be fed raw dry feed and raw wet feed. Feed after fermentation, silage, chopping and other processing, should be properly squeezed to break up. But drink enough water after feeding.

3. Eat less and eat more. The number of meals is determined according to the type, age, season and feed nature of pigs. 7-day-old piglets were lured to eat unlimited meals; From the age of 20 to weaning, you can feed it more than 6 times a day; 4 weaned piglets a day? 5 times; Sow with young and sow in the third trimester of pregnancy 4 times a day; Shelf pig, big pig and boar three times a day. In summer, the days are long and the nights are short. Feed 1-2 times as appropriate. In winter, if the days are short and the nights are long, we should feed the first meal early in the morning, feed it at night and add meals at night.

4. What are the feeding requirements? Four decisions? . Namely qualitative, quantitative, timing and constant temperature. According to the different ages and uses of pigs, the corresponding diet should be prepared according to feeding standard, which requires comprehensive and balanced nutrition, complete species, diverse collocation, good palatability, high quality and freshness. Timing is beneficial for pigs to form habits, secrete digestive juice regularly and promote the digestion and absorption of substances. According to the nutritional status and appetite of pigs, it is generally appropriate to determine the daily feeding amount of pigs, that is, there is no food in the trough after feeding, and pigs do not lick the trough. Spring, summer and autumn are generally fed at room temperature, and in winter, feed is prepared with hot water and fed with warm water as appropriate.

Raising pigs is not only a traditional breeding industry, but also the focus of animal husbandry. Pork food is irreplaceable by other animal foods. In addition, growing food crops, vegetables and fruits requires a lot of agricultural fertilizers, and using biogas must also raise pigs. So raising pigs is even more important.

Raising pigs is a systematic project, which pays attention to seedling selection, ingredients, management and disease prevention. It is not easy to raise pigs well, but it is not impossible. In order to raise pigs well and improve their benefits, we must master the scientific knowledge of pig raising and constantly sum up and improve it in practice. To this end, the following mainly talk about the effective technical points of feeding and fattening, in order to help pig farmers raise pigs well and then raise good economic benefits.
