Soil improvement Some farmers raise local pigs and feed for 70-75 kilograms for more than 10 months, which is economically unfavorable. They should be fed three-way hybrid pigs or hybrid pigs.
The single-reform science test proved that the ratio of feed to meat was 7:1 with a single corn feed; the feed was mixed with corn and wheat bran, and the ratio of feed to meat was 5:1; prepared with corn, soybean meal, wheat bran and premix. The mixed feed is fed to pigs with a feed to meat ratio of 2.8:1. Promote the use of compound raw materials formulated feed to pigs.
Cooked raw feeds lose at least 10% of their nutrients after cooked, and the leftovers are left in place for a long time and are subject to deterioration, which can easily cause poisoning or diarrhea. Should be cooked and fed.
The old and new to constantly adopt advanced technology, change the traditional feeding method is an effective means to improve economic efficiency. At present, there is an active microbial feed that has been put on the market. With this kind of feed, the cost of feeding pigs is low and the pigs grow fast. At the same time, the feed is easy to preserve and has a long shelf life. It is green, environmentally friendly, flexible and effective in improving the pig's health.
Mixing and changing large and small pigs only need to be kept separately. If the big and small pigs are put together and fed together, the big pigs will eat more, and it will easily cause indigestion and even diarrhea. The pigs will not eat on the food and hungry.
When scattered pigs are scattered, they have a large amount of activity, consume much energy, and have a low feed conversion rate. After being changed to captivity, pigs sleep when they eat and can effectively increase daily weight gain.
Many pig farmers have had the idea of ​​"retreatment against light prevention". They are willing to spend money when they are ill, and they are reluctant to spend money during epidemic prevention. It is necessary to establish the idea of ​​"preventing the main thing and preventing the emphasis on the rule."
Eight
The timing and frequency of feeding the pigs every day should be fixed. Regular feeding can not only make the pig life regular, but also help the secretion of digestive juices, thereby increasing the pig's appetite and feed utilization.
Quantitative feeding requires a good grasp of quantity, which cannot be neglected, so as not to affect the pig’s appetite, cause indigestion, and reduce feed utilization. When formulating feeds, the quality must meet the feeding standards first, and the proportions of fine, coarse, and green feed must be scientifically arranged, and the types and proportions of feeds must be relatively stable and cannot be changed too much. This can increase the appetite of pigs and improve Feed digestibility and utilization.
Definitely defined feeding allows the breeder to have a detailed understanding of the pig's habits, while the pig can adapt to the feeding method. When it is necessary to change breeders, the “old belt is new†should be implemented, and the new breeder should be familiar with the period of time before changing.
Positioning pigs to develop a good habit of eating, pulling, sleeping positioning. Before entering the pigs, clean up and disinfect the pens, place some grass in the places where they are sleeping, sprinkle some water in the places where they are pulled, and sprinkle some food in places where they eat. The first three days should be cleaned and diligently tuned. Generally, the “three positioning†habits can be formed after 3 days.
Regular deworming should generally be carried out once a year in spring and autumn. Finishing pigs can be dewormed every 1 to 2 months.
Routine vaccination is generally conducted in the spring and autumn of each year. After the full-born piglets should be vaccinated against paratyphoid freeze-dried attenuated vaccine, every 3 to 7 days and then inoculated with swine fever, erysipelas and triple vaccine. In addition to routine prevention, it is necessary to inoculate vaccines such as encephalitis, foot-and-mouth disease, and Eperythrozoon.
Regular disinfection should generally disinfect the homes and the environment every 3 to 7 days. Disinfection can be used lime milk, fire alkali, quicklime powder, 10% bleaching powder and so on.
