CATDOLL : CATDOLL: How to treat bullfrogs that die when their skin turns yellow?

1. How to treat bullfrogs that die when their skin turns yellow?

Bullfrog skin rot is mainly caused by nutritional deficiency, especially vitamin deficiency or skin damage leading to bacterial infection. When the disease occurs, the bullfrog's skin loses its luster and white spots appear. As the disease progresses, the skin begins to fall off and rot, exposing the back muscle tissue. In severe cases, it spreads throughout the body, and black granular protrusions appear in the eyes, which can lead to loss of vision.

Prevention and control methods: Change water regularly, strengthen water quality management, disinfect frequently, strengthen nutritional adjustment, and mix vitamins and nutrients into the bait.

Bullfrog skin processing method: First, cut off the head of the bullfrog. Use a kitchen knife to cut a cut from the back of the bullfrog to the buttocks (just cut the skin). Pull off the skin from the cut back, grab the bullfrog's back spine with your right hand, and pull the skin on the bullfrog's back down with your left hand. When the skin is pulled to the bullfrog's front and back feet, cut off the bullfrog's toes. Ranacates beiana, a solitary aquatic frog, is named for its loud and resonant call that resembles the call of a bull, hence the name bullfrog. It is the largest frog in North America. It is named for its loud call, which is loud and resonant like the call of a bull, hence the name bullfrog. Bullfrogs are the natural enemies of amphibians. They are native to several states in the eastern United States and were later introduced to western states and other countries. Bullfrogs are green or brown in color, with white to light yellow abdomens and black stripes on their limbs.

2. Symptoms of bullfrog disease

Red leg disease: The muscles of its legs and abdomen are congested in spots, and in severe cases, all muscles turn red. Skin rot disease: The skin on its back loses its luster and white spots appear, and then the epidermis begins to fall off, and the skin rots and turns white. Gastroenteritis: It has an unstable habitat and swims slowly. It likes to burrow into the mud or lie flat on the edge of the pool.

3. How to treat bullfrog hepatobiliary syndrome?

As the water temperature continues to rise in summer, bullfrogs eat and grow more vigorously, and the amount of feeding is also increasing, which leads to increasingly serious liver and gallbladder diseases. Long-term feeding of high-energy and high-protein feeds overloads the digestive organs such as the liver and intestines of bullfrogs, leading to excessive fat accumulation in the liver and abdominal cavity, damage to the liver, gallbladder and intestines, and causing liver enlargement and enteritis, which seriously restricts the growth and development of bullfrogs. In severe cases, it can also cause death and losses, which must be taken seriously.

Bullfrog hepatobiliary disease can occur throughout the year, mainly from May to October, especially during the high temperature period in summer, from young frogs to adult frogs, and the mortality rate is as high as 40% to 90%. Bullfrogs with hepatobiliary disease are obese, with yellow-green and dull skin. Autopsy shows ascites and enlarged liver. The liver turns grayish white, khaki or blue-gray, and the gallbladder is enlarged and light green.

The liver is the most important metabolic organ in the bullfrog's body. In daily breeding, we must pay attention to liver health. Once the bullfrog's liver is damaged, it will directly lead to metabolic dysfunction and reduced disease resistance in the bullfrog, allowing bacteria to take advantage of the opportunity to enter. Bacterial diseases can cause complications of multiple diseases and accelerate death.

Bullfrog hepatobiliary disease seriously affects growth and development and may even cause death. How can we prevent and treat it?

Bullfrog liver and gallbladder disease has a long course of disease. The early symptoms are not obvious and are generally not easy to detect. By the time the symptoms become obvious, the frog is already close to death. At this time, the frog's body is extremely swollen and it is too late to rescue it. Therefore, in daily breeding, it is necessary to do a good job of bullfrog liver health care in advance:

1. Control the amount and frequency of feed, feed reasonably, and reduce the burden on bullfrog liver and gallbladder;

2. Use drugs rationally and symptomatically, especially avoid overuse of antibiotics, disinfectants and pesticides. Drug abuse can also damage the internal organs of bullfrogs. 3. Daily health care is of utmost importance. Add Longchang bile acid, which protects the liver and gallbladder, to bullfrog daily feed. On the one hand, bile acid can inhibit the excessive accumulation of fat in the bullfrog's liver and abdominal cavity, reducing the burden on the liver and intestines; on the other hand, bile acid makes up for the lack of bile secretion when the bullfrog's liver and gallbladder are damaged, dredge the bile duct, enhance liver function, promote liver detoxification and excretion, and play a role in protecting the liver and gallbladder, repairing liver and gallbladder damage, thereby effectively preventing and treating the occurrence of bullfrog liver disease.

4. Why are bullfrogs prone to hepatobiliary syndrome?

1. Nutrition

① Feed nutrition is unbalanced.

2. Management

① Improper feeding.

Feeding too much or too often may cause bullfrogs to eat too much, or frequent feed changes may lead to unpalatable or nutritional stress and strain on the liver.

② The breeding density is too high.

The breeding density is too high, the bullfrogs’ growth environment is poor, they are in a sub-healthy state, and the burden on their liver is increased.

③ Drug abuse.

Indiscriminate use of products, such as the misuse of antibiotics and pesticides, will directly increase the burden on the liver and even lead to poisoning.

④ Water quality deteriorates.

If the water quality is not properly regulated, the water environment balance is broken, and the indicators such as ammonia nitrogen, nitrite, and pH value in the water are unbalanced for a long time, it will lead to increased exogenous stress on the bullfrog's liver and gallbladder. For example, when the concentration of ammonia nitrogen in the water is too high, it will cause an imbalance in the bullfrog's metabolism and lead to liver and gallbladder diseases.
