Low-carbon type penaeus monodon compound feed

Abstract

The invention relates to a low-carbon type penaeus monodon compound feed which is characterized by comprising the following components by weight: 180-250 kilograms of Shandong domestic fish meal (anchovy), 40-100 kilograms of chicken meal, 50-80 kilograms of cottonseed meal, 80-150 kilograms of soybean meal with skins (46%), 40-80 kilograms of rapeseed meal, 30-70 kilograms of cottonseed protein, 80-150 kilograms of peanut bran, 180-230 kilograms of high gluten flour, 20-40 kilograms of soybean lecithin powder, 15-25 kilograms of seawater fish oil, 8-15 kilograms of soybean oil, 7-12 kilograms of monocalcium phosphate, 0.3-1.0 kilogram of vitamin C-phosphate, 2-5 kilograms of 50% choline chloride, 0.5-1.5 kilograms of taurine, 0.5-2 kilograms of high-temperature-resisting phytase, 0.5-1.5 kilograms of allicin, 0.5-1.5 kilograms of prawn molt, 2-5 kilograms of compound vitamin pre-mixture and 3-10 kilograms of compound multi-mineral pre-mixture. The feed disclosed by the invention can improve the utilization efficiency of the feed by penaeus monodon, reduces the discharging of nitrogen, phosphorus and heavy metal elements including copper, zinc, cobalt and the like and is good for environmental protection; and the raw materials of the compound feed are stable in sources and low in price.

Description

technical field [0001] The patent of the invention relates to a feed, in particular to a low-carbon type Penaeus vannamei compound feed, which belongs to the technical field of aquaculture feed. Background technique [0002] Penaeus vannamei, also known as Litopenaeus vannamei and white-footed shrimp, is native to the coastal waters of South America. It has fast growth speed, strong resistance to water environment, large individual, beautiful meat quality, low nutritional requirements, fast growth speed, It has many characteristics such as high body meat content, and is one of the three largest species of farmed shrimp in the world. Since the 1990s, vannamei has become the largest prawn species in my country, accounting for more than 90% of the total prawn production. [0003] With the continuous expansion of the farming scale, it also promotes the rapid development of the shrimp feed industry. However, because the current feed utilization rate is not high, in the farming ...

Problems solved by technology

However, because the current feed utilization rate is not high, in the farming practice, the excess nutrients (especially nitrogen and phosphorus) in the diet are excreted into the aquaculture water environment through metabolism. In addition, a considerable proportion of heavy metals in the feed such as zinc, Copper, cobalt, etc. are also excreted into the water body, leading to serious pollution and eutrophication of the water body, which seriously threatens the sustainable and healthy development of the shrimp industry
