Abstract

The invention discloses a high-efficiency feed for enhancing the ammonia nitrogen tolerance of Litopenaeus vannamei, which is made of the following raw materials: fish meal, spray-dried porcine blood globulin powder, hydrolyzed feather meal, shrimp shell powder, squid paste, fermented soybean meal (IV ), peanut meal, high-gluten flour, corn DDGS, rice bran meal, refined fish oil, choline chloride, soybean lecithin oil, L-ascorbic acid-2-phosphate, calcium dihydrogen phosphate, vitamin premix, mineral premix feed, antifungal agent, food attractant and tolerance additive; the beneficial effect of the present invention is: the feed of the present invention can not only improve the activity of antioxidant enzymes and digestive enzymes in Litopenaeus vannamei, but also can effectively improve the activity of Litopenaeus vannamei. The tolerance of prawns in high ammonia nitrogen water body can obviously reduce the mortality rate of Litopenaeus vannamei in the environment of high ammonia nitrogen water body. In addition, each raw material of the present invention cooperates with each other and works together to significantly improve the survival rate of Litopenaeus vannamei, The advantages of feed conversion rate and feed coefficient.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a high-efficiency feed for enhancing the ammonia nitrogen tolerance of Litopenaeus vannamei. Background technique [0002] Litopenaeus vannamei, also known as Penaeus vannamei, is a kind of aquaculture shrimp with delicious meat, strong disease resistance and fast growth. This kind of shrimp is mostly fed in a high-density farming mode. This farming mode makes the shrimp excrement With rapid increase, the ammonia nitrogen content in the water body rises. The harm of ammonia nitrogen to aquatic organisms mainly refers to the harm of non-ionic ammonia. Exceeding the standard for a long time is seriously toxic to aquaculture aquatic products, reducing the activity of antioxidant enzymes such as superoxide dismutase (SOD) and phenoloxidase (PO) in the body, affecting the resistance and stress resistance of Litopenaeus vannamei Sexuality, prawns will have dyspnea, convulsions, co...
