vital to the health of piglets in pig farms, conservation stage, we nursery stage What are the attention of the key? Is it only to rely on “drug” to do health care? I think feeding management is the key, and there is a total of three issues and everyone’s problems in the past three phases of the province. Today is the second part.
(received yesterday’s push)
6. Pay attention to the preservation and use of the drug:
To ensure the treatment effect, the producer should properly use and properly preserve drugs. Here are some points:
1) Read the label carefully when using and preserved drugs, and store and use drugs as described.
2) Ask the veterinary consultation, such as how to use, and dose.
3) Read the instructions in the box with unfamiliar drugs.
4) Remember not to inject stress and sick pigs.
5) Remember that cleaning is the foundation of pig pigs. The injection vaccine should use a clean needle, needle tube, and disinfect the neck injection zone.
Producers should often discuss with your veterinary consultants on specific diseases, and their most effective medical methods. Develop a pig health plan and procedure, including veterinary regular inspections, which will help producers control disease and ensure normal production.

It is best to control inner parasites before childbirth. The liver inspection of feces floating objects and sick pigs is the best way. These methods can decide whether to deworming is needed. “Milky White Point” and the insectica eggs in the liver and the fecal woofer can be proven to be insecticidal.
Some dewormy drugs can be used for injection, mix into water and feed. Select insecticide to determine the type, labor and equipment of parasite.
ExternalParasites, such as in some pig farms, there is a scent and scorpion. These parasites can be used to remove insecticormation.
The right control of the pig farm should start from the sow. Remember to control and remove external parasites through a health prevention system.
8. Precautions for feeding wear pigs
Before and after weaning, it will provide appropriate nutrients will have a big difference. The production person’s goal is to let the freshly weaned pigs eat dry materials while reducing interference to growth.
The concept of digestive system:
Small pig’s digestive system specifically digested cream, lactose and milk protein in the mother’s milk. Before weaning, pigs have a small amount of breast milk, so that each pig is ingestion. Under such conditions, the pig is not necessary to develop its own storage capacity because there is enough parent and regular supply.
Digestive vegetable feed requires a specific digestive enzyme. After weaning, piglets take a week or more time to produce and develop these enzymes. When the pig lacks these enzymes, the ability to digest vegetable proteins and energy is poor. Therefore, the correct initial diet raw materials and feeding techniques are to avoid interfering to digestive systems and remain grown.
The five kilograms of heavy pigs have a daily growth of 400 grams of genetic potential. Ten kilograms of heavy pigs have a daily growth of 700 grams of genetic potential. Twenty kilograms of pigs have a daily growth of 1000 grams of genetic potential. It is generally difficult to produce this level of production, even the high production capacity of pigs is 30% more than this level.
The low growth rate in the contributions will always affect the seeding period. Therefore, there is no matter how much improvement will increase in the birthday period of the future, if the piglet is not good in the childcare period, this will cause the pig to reach the time of the listing weight.
Develop a correct feeding strategy:
The initial day grain attempts to maximize the growth rate, and no profit is maximized. Cheap feed on the market often does not meet the nutritional needs of weaning piglets. Therefore, a good feeding strategy is to consider production growth and feed costs.
Feed raw materials must match the development of the pig digestion system. In order to avoid digestive disorders, weaned pig feed contains nutrients that are easy to digest, such as skim milk powder, whey powder, glucose, fishmeal, mad protein powder and vegetable oil, with the hair of the digestive tractFeeding, low cost, poor digestive ability. This strategy will be based on the entire strategy with low-cost feed. A low-cost fed strategy requires often checking growth rates and may cause damage to the intestine and dysenter.
I will give a dietary formula (first stage feed) for 5 kg to 10 kilograms of pigs. Feeding this diet during the first 7 days or 10 days after weaning, the pig is adapted to dry feed while rarely interfere with the digestive function.

Although some of the sowed pigs It can take advantage of a low cost and low digestive ability, but such feed may be harmful to other mature pigs, resulting in dysentery. Excellent initial diet should take into account more than 75% of piglets.
The pig weight is suitable for use with low digestible feed, which can be replaced with a second stage of feed. The second phase of feed can utilize low proteins and energy feed sources. If you continue to dysen, you should delay the feed.
Fig. 3 shows that at the last two weeks of food, 70% of the feed is consumed at the last two weeks. This phase provides cheaper feed, which will effectively reduce feed costs.

Advantages and Disadvantages of Telling
The breastfeeding trough feeding will affect the production performance after weaning. The benefits of tap feed increase from 10% to 15%, and the digestive system is more complete.
Breastfeeding pigs can increase the weight of the weaning weight of 10% to 15% during this period, and the digestive system is more complete. When the pig weaned 4 weeks ago, the pig is impossible to add these feeds (Figure 3).
The teaching can be fed to some disadvantages. When the pig has only a few feed during lactation, it may generate allergic reactions to certain nutrients, which may cause digestive disorders. Therefore, the trough feed intake is a worse result compared to not feeding the chronic feed.
If weaning, before weaning, the trough feed is less than 400 grams, and should consider the following measures:
1) Weaning can be appropriate for a few days. 2) After weaning, do not feed the trough feed, directly feed solid feed to avoid allergies.
3) If you use the teaching trough feed, you should take the trough feed to remove the allergenic source.

Select feeding form:
The particulate feed can be improved by 5% and the meat is more than 10%. Pigs prefer small particle feed, so in 5 weeks old, the particle feed diameter of the pigs is not greater than 2.5 mm. At the same time, it is necessary to pay attention to the lower compression ratio of the ring model when the feed is processed.
Ferrated piglets need to balance two factors:
1) is not limited to achieve maximum growth speed.
2) may need to be restricted, avoiding dryness after weaning. The difference is if youIt is not necessary to restricted the dietary diet. However, in order to save feed costs, feeding that is not too expensive and less easy to digest. If this is done, the first five days after weaning should control the feeding capacity or provide 4 to 5 small amounts of feed, prevent digestive disorders. Increase feed feeding daily, and will recover free food level in the fifth day after weaning.
