Full price pellets vs. premixed from ingredient safety
African piglets have entered China, and pig farmers have suffered heavy losses. While we reflect on how farms can enhance biosecurity, and also ignite the security battle between full-price materials and pre-mixtures, let's analyze this dispute and discuss the role that feeds need to bear. Let's see what we can find.
　　 1. The experience of Poland.
a. Poland saw the first African swine fever in 2014, Dr. Woźniakowski, director of the Polish National Laboratory Pig Disease Center, shared the results of the first 12 diseases transmitted in Poland, as shown below, wild boar, drowning, and illegal reselling transport Sick pigs are the main route of transmission.
b. Feed does not cause the spread of African swine fever
c. Dr. Woźniakowski, director of the National Laboratory of Pig Diseases at the National Laboratory of Poland, showed that after artificially infecting feed ingredients, after being placed at 22 degrees Celsius for 7-8 days, the feed ingredients artificially infected with African swine fever virus are no longer infectious. . (Pejsak et al., 2018)
d. German African piglet reference laboratory Dr. Sandra Blome and an academic exchange on April 25, also confirmed the results of her laboratory, after 7-8 days at room temperature, 7-8 days, African swine fever virus in dry vaccination The substance has lost its vitality.
2. Estonia's experience
a. The situation in Estonia is similar to that in our country. The situation of infected pigs in African pig farms is greater than in pig farms.
b. Polluted vehicles and personnel are the main means of transmission.
c. The number and intensity of contact with the external environment is more, and it is closer to other farms, making the pig factory more susceptible.
d. Feed does not cause the spread of African swine fever
3. Current EU regulations
a. Commercially purchased crops, vegetables, hay and straw are very low in infection and retain viable African swine fever virus.
b. If it is considered that the grass and straw harvested locally in the affected area are dangerous, it is forbidden to feed fresh grass or freshly harvested grain, and after feeding inactivated, it can be fed or placed for 30 days.
c. Simply placed for 30 days can kill the virus very effectively and increase the safety of the feed.
4. China Experience
a. Of the 68 African swine fever cases identified for transmission, none of them were fed.
b. There are three main routes of transmission, such as transporting pig carts, personnel, and feeding uncooked drowning water. This is consistent with the EU's summary.
c. Large-scale pig farm facilities are very good, but the lack of software such as the biosafety awareness of personnel is an important reason for the spread of African swine fever in Chinese pig farms. As shown in the following figure, a realistic example of a pig farm with 4,500 sows is the main reason why employees' biosafety awareness is not in place.
Conclusion:
The feed did not cause the pig to be infected with the African swine fever virus. Commercial feeds are inherently safe, and full price pellets and premixed ingredients are safe. The full-price material can increase the safety by high-temperature granulation, and can also increase the safety of the finished material placement time. Premixing can increase the shelf life of the finished product and increase safety. The focus of the farm should be on the biosafety of the farmer.
In the context of African swine fever, what do I need to ask for feed?
Safety. As mentioned above, the feed is very safe. Both full price and premix can increase safety through some measures.
I think we should return to the essence of feed, that is nutrition and health. Under the non-conspicuous panic, some farmers do not talk about the nutritional properties of feed. They believe that growth performance is not important, and safety is more important. As long as they can keep pigs, they can make a fortune in the second half of the year. Dr. Sandra Blome, a reference laboratory for the German African swine fever, reported in a 2015 article that the weakest or slow-growing pigs in the herd were more susceptible to low-dose African swine fever virus. The results of this experiment tell us that pigs need good nutrition to support growth and development, and pigs with good growth and development have better disease resistance. We need to return to the nutritional properties of feed and return to the growth performance and health of feed. Requirements.
