Causes and Solutions of Diarrhea in Early-Weaned Piglets
The causes of post-weaning diarrhea in piglets are complex. Research over the past 20 years has shown that dietary factors are the main cause of post-weaning diarrhea in piglets. The reasons are: (1) A certain number of pathogenic microorganisms (pathogenic Escherichia coli and rotavirus, etc.) generally exist in the gastrointestinal tract of healthy piglets. (2) Introducing isolated pathogenic microorganisms into the gastrointestinal tract of unweaned piglets and weaned piglets that are either not supplemented or fully supplemented with feed did not always cause diarrhea. (3) The proliferation of intestinal pathogenic microorganisms is not necessarily linked to post-weaning diarrhea. (4) When no pathogenic microorganisms are present or proliferating, weaned piglets can still develop diarrhea. (5) If weaning does not cause intestinal damage, piglets will not develop diarrhea, although pathogenic Escherichia coli can still be detected in piglet feces. (6) Practice has proven that antibiotics are not completely effective in preventing and treating post-weaning diarrhea in piglets.

Key Points and Precautions for Piglet Weaning Technology
From the sow's farrowing until the piglets become nursery pigs, they must go through the weaning process, which greatly affects the piglets' development. Everyone also knows the saying that a one-jin difference in body weight during the piglet stage can mean a ten-jin difference at the time of finishing. Therefore, doing a good job of weaning piglets is clearly very necessary.

Can Piglets Be Weaned in Summer? Detailed Explanation of the Specific Methods
The feeding and management level of weaned piglets is an important part of ensuring the profitability of large-scale pig farms. During the nursery stage, the maternal antibody level of piglets and the piglets' own immune level are relatively low. In addition, stress of varying degrees from group transfer, environment, and feed changes brings certain difficulties to

Reasons and Solutions for Sows Not Coming into Estrus After Weaning
Under normal circumstances, sows will come into estrus about one week after weaning. But quite a few farmers report that their sows still do not come into estrus ten to twenty days after weaning. Why is that? What should be done? What should be done if a sow does not come into estrus after weaning? First, feeding should be strengthened, choosing a complete feed specially designed for lactating sows, and feeding 3-4 times a day to ensure that weight loss at weaning is not excessive; second, ventilation in the pig house must be ensured, and cooling is needed in summer. In addition, for sows that do not come into estrus, an appropriate dose of diethylstilbestrol, anterior pituitary gonadotropin, cloprostenol, etc. can also be injected intramuscularly.

Analysis of the reasons why young rabbits are prone to disease after weaning
After weaning, young rabbits face changes in environment and feed, and the stress responses caused by these changes are an important reason why young rabbits become ill after weaning. 1. Environmental stress: young rabbits are moved to a new environment and do not adapt. The physiological functions of weaned young rabbits are still not fully developed,

What are the common misconceptions in wild boar farming?
1 Weaning too early. Many farmers, when raising wild boars, artificially wean the piglets early in order to breed them sooner and bring the piglets to market earlier. Because wild boars have underdeveloped mammary glands, a small milk yield and a short lactation period, weaning too early easily leads to piglets that are small in size, weak in constitution,

How to raise Rex rabbit kits well? The key is to grasp three critical stages
Ensure a good weaning stage. Young rabbits start eating at 16 days, fed a small amount of easily digestible tender grass, vegetable leaves, etc. At 22 days, begin providing complete-price feed, and feed small amounts frequently. When young rabbits are 28-42 days old and reach a weight of 750 grams, they can be weaned. Use the intermittent weaning method, nursing once every other day, and after the

The weaning methods are as follows: 1. One-time weaning method: On the weaning date, forcibly separate the mastiff pups from the female mastiff. Its advantages are a short weaning time and early separation into litters;

What to do about coughing and wheezing in weaned piglets? Experience sharing on traditional Chinese medicine prevention and treatment in pig farming
Coughing and wheezing in piglets from 10 days after weaning to 30 kg body weight is usually associated in Western veterinary medicine with porcine postweaning multisystemic wasting syndrome (i.e. circovirus) infection, with an incidence rate ranging from 20 percent to 45 percent; the mortality rate of affected piglets is generally 30 percent, and can reach as high as 80 percent, with body temperature of 40.5°C to 41.5°C. Piglets show rough and disheveled coat, affected pigs have diarrhea combined with respiratory symptoms and neurological symptoms, severe emaciation, and death from exhaustion. This disease poses a very great threat to the pig farming industry. It is most severe in the three seasons of spring, autumn and winter. In traditional Chinese veterinary medicine theory, this disease belongs to warm disease symptoms; the cause is external contraction of wind pathogen invading the lung, and cold, summerheat, dryness, warmth and the like can all combine with it. The main site of the lesions is in the lung. In traditional Chinese veterinary medicine theory, lung qi governs respiration and opens into the nose, externally corresponding to the skin and hair, and governs the opening and closing of the interstices. When lung qi is sufficient, the opening and closing of the skin and interstices is normal, and external pathogens are not easily able to invade; otherwise the pig body is plagued by disease. Using Qingfei Zhike San combined with Maxing Shigan San with modifications, this formula can pungent-cool diffuse and vent, clear the lung and calm wheezing, clear and purge lung heat, and resolve phlegm and stop coughing. Add it to piglet feed as a powder at 0.6 percent, continuously for 2 to 3 weeks. In Western veterinary medicine theory, this formula is believed to have fairly strong antibacterial and inhibitory effects on Actinomyces pleuris, Staphylococcus aureus and Pneumococcus; this formula also has effects such as anti-influenza virus action, and also has obvious antipyretic and anti-inflammatory effects, and can improve the immune function within the animal body.
