Customers are advised to replace rancid domestic fish meal with imported fish meal and stop using original yeast powder. Add 4 packs/ton of "nutrition express" to the feed. As a result, it soon recovered after eating, and the digestive tract diseases were alleviated. However, customers see that the food is good, so they add the remaining low-quality domestic fish meal to the compound feed, and so on. After a month's repetition, the pomfret ate normally, and the three sheds fed nearly 4000 kilograms of feed every day. And there was no obvious disease before the fish came out. It turned out that the customer thought the compensation was settled, but the income was quite rich that year.
Analysis: 1. Because of the low cost, customers in many areas make their own ingredients, but they are often not sure about the quality of feed raw materials. Deteriorated raw materials, in particular, can cause gastrointestinal diseases, resulting in inability to feed and even death.
2. In this case, the gastrointestinal disease of freshwater pomfret was very serious, but it didn't die, because the customer fed antibacterial drugs and controlled the bacterial infection.
3. "Nutrition Express" (multivitamins) has an outstanding effect in adjuvant treatment of diseases, especially those related to nutrition.
? 4. It used to be added to feed as an attractant to stimulate the appetite of fish. But most of them are still used for drug bait feeding. Adding proper amount of salt can improve the therapeutic effect of drug bait, which is generally 10- 15g/kg feed. Using 1 kg salt and garlic as bait for every 200 kg fish, feeding for 7 days continuously for a course of treatment can prevent gill rot and enteritis. For every 200 kg grass carp, use 4 kg garlic, peel and mash it first, then add 20 kg rice bran, 2 kg flour and 2 kg salt, stir well, and feed it 1 time every day, five times in total. Days, can prevent and treat "old three diseases" bacterial gill rot, erythroderma and enteritis.
