Recently, the news that the price of live pigs has risen has continued to spread. Many farmers have begun to reluctantly sell, and even the sows that are screened are not willing to be screened.
However, the market is changing rapidly. As the farmers reluctantly sell, there are also many local hog prices that have begun to fall. Therefore, the farmers raised their names and said, "The pig market really can't understand."
The author believes that the selection of fertile sows is a necessary process in breeding, and has nothing to do with profit or loss.
If we can improve the utilization of fertile sows, of course, the best, if not, we should quickly filter to avoid affecting production.
In the implementation of screening for fertile sows, each pig raising unit needs to achieve “two adherencesâ€. Adhere to science. Darwin said: "Science is to pick up the reality, discover the rules and make a final conclusion."
Therefore, the author believes that screening for fertile sows needs to be scientific.
First of all, we must screen sows suffering from viral epidemics. Such sows have epidemics such as swine fever and pseudorabies. Even if they are cured with drugs, they may have hair disease and spread to piglets during farrowing.
The second is to screen for sows that exhibit breast inflammation, uterine inflammation, and significant decline in suckling piglets. The sows are mainly unable to feed the pigs;
The third is to screen sows with defective limbs. If a sow whose legs are not able to move normally and has poor health, piglets will not be healthy even if they give birth to piglets; the fourth is to select sows that are older and have a lower birth rate; the fifth is to screen. Breeding sows that are difficult to succeed, easily producing deformed piglets, etc.
Adhere to reason
The utilization rate of progressive fertile sows not only can prolong their lifespan, but also improve the production function of the life cycle. It can also help reduce the cost of the breeding pigs allocated to each commodity pig and increase production power.
For this reason, the author believes that in the selection of fertile sows, each hog feeding unit must be able to adhere to rationality, overcome agitation, and resolutely avoid “one size fits allâ€.
The author also advocates that each hog feeder unit should contact the situation at that time, carefully analyze the status quo, and focus on the development of a targeted, batch-by-batch approach to the gradual selection of relatively debilitated sows so as to avoid disabling the production of pigs in later stages, and then affecting the unit’s production. Long-term development of policies and long-term economic benefits.
