How to raise pigs, it is best to have a video.

1, determine the type and dosage of materials.

Note: straw should be cut into 8-10 cm in advance; Can not be used after anti-corrosion treatment; The quality of rice bran is good, and adulterated rice bran or rotten rice bran cannot be used.

In winter, the south of China is 60cm, 60cm and 80cm.

The yellow river basin in north China is 80cm 100cm.

North (Northeast, Northwest, Inner Mongolia) 100cm 120cm

50 cm South China 50 cm in summer.

The Yellow River basin in northern China is 50 cm and 60 cm.

North (Northeast, Northwest, Inner Mongolia) 60cm 80cm

3. Production of yeast bran

Mix the required Luodong A-90 and a certain amount of rice bran evenly to make 10% enzyme bran for later use.

4. Stacking fermentation

1) Take 10% unfermented chaff and sawdust for later use, and pour the remaining chaff, sawdust, Luodong A-90 (enzyme chaff), pig manure, rice bran and other materials. According to the proportion of the above materials, put them into the padding yard, fully mix and stir evenly, first turn them from the middle of the padding to both sides, then turn them from both sides to the middle, and finally turn them to one end of the pigsty.

2) During fermentation, measure the fermentation temperature every day and make records. From the next day, the temperature was measured at three points at different angles, the depth was about 20cm, the temperature could be raised to 45℃ -50℃, and then gradually increased to about 65℃ -70℃, then the fermentation was successful.

3) When the fermented padding is pushed away, there will be a fresh smell, which can be spread out in the barn when there is no smell. Then, the reserved chaff and sawdust are mixed with 65,438+00% respectively, and covered evenly, with a thickness of about 65,438+00 cm, and pigs can enter after 24 hours. , production characteristics

Large-scale pig raising refers to the comprehensive application of science and technology such as farmhouse music, agriculture, management, animal husbandry and veterinary medicine. By the production unit or professional households to achieve high-quality and high-yield economic pig raising effect, to provide a large number of high-quality and cheap commercial pork. The scale of large-scale pig raising has been expanded, the degree of specialization and intensification has been improved, pigs have grown and fattened quickly, the slaughter turnover has been accelerated, the weight gain and material consumption have been reduced, and the utilization rate of pens has been high. China has a large population and abundant labor resources, but the per capita resources are scarce. Therefore, large-scale pig raising should pay attention to economic, social and ecological benefits.

[Edit this paragraph] 2. scale of operation

Since the 1980s, due to the continuous development of pig breeding, the scale of pig breeding has become larger and larger, with an annual output of 654.38+10,000 and 20,000, and commercial pig farms have developed rapidly. Suppose a pig farm with an annual output of 10000 pigs, if the slaughter rate is 75% and the slaughter weight of each pig is 100 kg, the annual output of pork can reach about 750000 kg, and the monthly output of fat pigs can reach more than 800. The scale of operation is closely related to natural, economic, technological and social factors in a certain period and scope. In particular, the quantity and quality of feed resources play a very important role in the scale of operation.

[Edit this paragraph] III. Feed processing

Large-scale pig-raising units must build feed processing plants of corresponding scale according to the production scale and long-term tasks. Suppose a pig farm with an annual output of 10000 pigs weighs 100 kg and needs 3 kg of concentrated feed for each gain 1 kg, then each pig needs 300 kg of concentrated feed, totaling 3 million kg. There are 500 breeding sows, each with an annual output of 2, and 20 surviving piglets. Under the condition of artificial insemination, the male-female ratio is calculated as 1: 100, and 5 boars need to be raised. Each breeding pig consumes about 0. 1000 kg of concentrated feed every year, and needs 5 10000 kg every year. Therefore, the audience needs about 3.5 million kilograms of concentrate.

[Edit this paragraph] 4. scientific management

Scientific management in large-scale pig production is the central link to organize production reasonably, improve work efficiency, produce more products and reduce costs. Scientific management should first make an annual production plan, arrange the division of responsibilities of various departments, coordinate and cooperate, and formulate labor quotas and post responsibility systems. It is required to standardize varieties, rations and scientific feeding. Every production link should be coordinated. Regularly announce the production progress, completed tasks, output value and cost of each group, so that everyone can know fairly well.

[Edit this paragraph] V. Epidemic prevention system

Large-scale pig raising is a place with high pig density, so we must attach great importance to the health and epidemic prevention system. It mainly includes: a thorough disinfection system (purifying the environment and preventing the invasion of germs); Regular epidemic prevention system (vaccine type, epidemic prevention time); Regular deworming system (deworming drugs, time); Emergency epidemic prevention system (isolation and blockade, pathogen diagnosis and measures), etc. Implement the policy of "prevention first, comprehensive prevention and control", and achieve strict quarantine, strict disinfection and regular immunization.
