Fish feed is an important source of high-quality feed for alfalfa, which contains high animal protein. Fish feeds are mainly produced in China's coastal areas and inland rivers, lakes, ponds and reservoirs. Although fish feeds are very good, if they are used improperly, it is difficult to achieve the intended purpose and effect. For this reason, the author The following is a description of the correct use and attention of fish feeding. 1. Pay attention to reasonable collocation: In the process of feeding fish feed, raising fishermen need scientific and reasonable matching with all kinds of fish species. The practice of breeding in local areas shows that it is better to feed the hybrid fish in the same period of time. The effect is good. It is better to use simple fish with high fat content than with fish with low fat content. If 60 to 70% of fish are mixed with 30 to 40% of meat, their production Better results. 2. Feeding fish without using deteriorating fish: Although the amount of fat contained in fish feed is lower than that of meat, the proportion of unsaturated fatty acids contained in the fish feed is relatively large, so it is easy to oxidize, thus forming a harmful effect on leeches. Substance, for this reason, should not be fed with deteriorating fish feed. If a group of fish fed long-lived, oxidized fish feed, vitamin deficiency, especially adipose tissue inflammation and abscesses, can easily occur in the blister, which can lead to a significant decline in otters' fertility and fur quality. If quail feeds this feed during pregnancy, it will cause adverse effects such as empty arms, stillbirth, rotten fetus, and embryo absorption. Feeding this type of fish feed to 2-3 months of pups can cause pups to develop yellow fat. 3. The feeding method should be appropriate: all kinds of fresh sea miscellaneous fish can be fed raw, cold storage should be first frozen, washed dirt and dirt, and then crush raw feed. Thiamine enzyme contained in freshwater fish can destroy thiamine (vitamins) in feed. For this reason, heat treatment should be taken before feeding, preferably by high pressure cooking or steaming with a rice cooker. Do not boil it with water. In addition, attention should be paid to increasing the amount of yeast used to make up for the deficiency of the vitamin B family. It is best to add antioxidant vitamin E in summer. If the leeches diet is based on whole fish, bone meal may not be added or reduced. 4. Note that picking toxic fish: In fish feed, some fish are poisonous, such as puffer fish, squid, etc. Any poisonous fish can't be used as feed for leeches. In addition, some fish have poor palatability, such as stingrays, small herring, octopus, etc. These fish can not be added too much in the feed. In some freshwater fish, there are many diseases, such as bacterial gill disease, bacterial enteritis, and erythroderma disease. When processing feed, it is necessary to carefully select and eliminate the fish, and to prevent poisoned fish from mixing into the feed. Fish with mucus on the body surface must first be stirred with 2.5% salt and then washed with clean water or scalded with hot water to remove mucus from the body surface and then used for leeches. 5. Feed treatment of other fish: For the light-dried fish used as mink feed, it must be soaked and softened with fresh water before it can be fed. For the use of alkali-dried fish and fish meal as a forage meal, it is necessary to fully carry out water-immersed desalination treatment. In many places, dried fish and fish meal are used as common feed for leeches, but it has been proved that their digestibility is low. Therefore, it is better to be fed with fresh feed after feeding. In particular, leeches should pay attention during the breeding period. At the same time, less fat is contained in dried fish and fishmeal, which is detrimental to the growth of leeks. When the leeches enter the hair replacement period, they must also pay attention to adding fats and oils to the feed. This will greatly improve the fur quality of the otters.
