Chicken infectious anemia-pathological changes
The most characteristic pathological change of simple chicken infectious anemia is bone marrow atrophy. The bone marrow of thigh bone is fatty, yellowish or pink; thymus atrophy and hyperemia can lead to complete degeneration. With the increase of age of diseased chickens, thymus atrophy is easier to observe than bone marrow lesions. Fabricius bursa atrophy is not obvious and is often transient. Sometimes the weight decreases and the volume becomes smaller, while the appearance of the bursa of most diseased chickens is translucent. If the condition is serious, the liver and kidney can be enlarged and the yellow substance becomes brittle.

Generally speaking, there will be the phenomenon of gluttony and rush to eat when they are about 35 days old. This kind of exuberant feeding phenomenon is called "prosperous food". Between the peak eating period and 60 days of age, the body weight of piglets can be doubled and the daily weight gain can reach more than 0.5 kg. The main measures for rapid weight gain of piglets during the peak feeding period are as follows: regular feeding and less frequent feeding. Starting from 30 days old, the times of feeding should be increased, usually 5-6 times a day, and for a fixed time.

Effect of low fiber diet on sows
The low content of crude fiber in diet can also cause a series of problems in pregnant and lactating sows. If it is easy to cause constipation in sows, the reason may be that feed stays in the digestive tract for too long, absorbs too much water, and dry feces cause constipation; in addition, digestive tract problems such as gastric ulcers in sows in factory farming may also be related to dietary cellulose content. If the sows in the early stage of pregnancy are fed a low-fiber diet, it is difficult to feel full due to the limitation of feed intake, which will lead to problems such as loop jumping.
