Problems solved by technology

At present, due to the one-sided pursuit of output and growth rate, and the lack of detailed and in-depth research institutes for soft-shelled turtles, feed manufacturers use high-protein feeds in soft-shelled turtle compound feeds (the crude protein content of juvenile and young turtle compound feeds is 47% respectively. and more than 46%), the content of fish meal used in the compound feed is 50-60%, and the phosphorus content in the imported white fish meal is very high (the phosphorus in the imported white fish meal is more than 3.5%), forming a soft-shelled turtle compound feed with high nitrogen, high The characteristics of phosphorus, so the current commercial feed is not an environmentally friendly feed, which is not good for the sustainable development of the soft-shelled turtle industry chain

Embodiment 1

[0017] An environmentally friendly compound feed for juvenile soft-shelled turtles, consisting of the following ingredients by weight: white fish meal 35%, red fish meal 19%, fermented soybean meal 7%, expanded soybean 4%, gluten 2%, beer yeast 8%, Pre-gelatinized starch 21.6%, calcium dihydrogen phosphate 1.5%, enzyme preparation 0.15%, microbial preparation 0.1%, compound multidimensional 0.25%, compound polyore 1%, 50% choline chloride 0.4%. These raw materials are mixed, crushed, and 100% passed through an 80-mesh sieve, which is an environmentally friendly compound feed for juvenile turtles. The feed ingredient distribution ratio in this example is reasonable, in which crude protein is 44.2% and phosphorus is 2.18%.

[0018] The compound feed for juvenile soft-shelled turtles in the control group consisted of the following ingredients by weight: white fish meal 41%, red fish meal 20%, soybean meal 3%, expanded soybean 4%, gluten 2%, beer yeast 8%, pre-gelatinized Starch 18.35...

Embodiment 2

[0023] An environmentally friendly compound feed for soft-shelled turtle larvae is composed of the following raw materials by weight: white fish meal 31%, red fish meal 20%, fermented soybean meal 8%, expanded soybean 5%, gluten 2%, and brewer’s yeast 7%, Pregelatinized starch 23.7%, calcium dihydrogen phosphate 1.5%, enzyme preparation 0.1%, microbial preparation 0.2%, compound multi-dimensional 0.2%, compound polymine 1%, 50% choline chloride 0.3%. After mixing these raw materials, they are superfinely crushed and passed through an 80-mesh sieve to form an environmentally-friendly mixed feed for soft-shelled turtle larvae. The feed ingredient distribution ratio in this example is reasonable, in which crude protein is 43.1% and phosphorus is 2.06%.

[0024] The compound feed for soft-shelled turtle larvae in the control group consisted of the following raw materials by weight: white fish meal 38%, red fish meal 20%, soybean meal 4%, expanded soybean 5%, gluten 2%, brewer’s yeast ...

Embodiment 3

[0029] An environmentally-friendly compound feed for juvenile soft-shelled turtle turtles is composed of raw materials of the following weight components: white fish meal 33.6%, red fish meal 21.3%, fermented soybean meal 7.2%, expanded soybean 4.3%, gluten 2%, and brewer’s yeast 8.4%, Pre-gelatinized starch 19.7%, calcium dihydrogen phosphate 1.5%, enzyme preparation 0.2%, microbial preparation 0.15%, compound multidimensional 0.25%, compound polyore 1%, 50% choline chloride 0.4%.

[0030] The feed of this embodiment was used to breed soft-shelled turtles in Tonglu, Zhejiang. Farmers reported that the water quality during the breeding process was more stable than when other feeds were used before, the amount of water exchange was significantly reduced, the growth rate of turtles was normal, and the common diseases of turtles were significantly reduced.

Abstract

The invention discloses an environmentally-friendly soft-shelled turtle compound feed, including the following material components (each component is in the air-dry substance weight percentage): 30-35% of white fish meal, 15-25% of red fish meal, 5-10 % of fermented soybean mea, 3-6% of extruded soybean, 1-4% of wheat gluten, 5-10% of beer yeast, 18-25% of pre-gelatinized starch, 1-2% of calcium phosphate, 0.05-0.3% of enzyme preparation, 0.1-0.4% of microbial agents, 0.1-0.3% of compound multivitamins, 0.5-1.5% of composite multi-ore, 0.2-0.5% of 50% choline chloride. The inventive prescription can reduce the nitrogen and phosphorus content in the compound feed, improve the digestive absorption and deposition rate of the nitrogen and phosphorus in the soft-shelled turtle breeding, and can reduce the output of nitrogen and phosphorus in water to improve the breeding environment.

Description

【Technical Field】 [0001] The invention relates to aquaculture feed, in particular to an environment-friendly compound feed for turtles. 【Background technique】 [0002] Turtle has the effects of nourishing and strengthening the body, prolonging life, and has high nutritional value. It is a traditional nourishing aquatic product in my country and has always been loved by the Chinese people. Since the 1990s, the rapid development of soft-shelled turtle farming in my country and the expansion of its breeding scale have become one of the main species of aquaculture in my country. At present, turtle farming mainly adopts two methods: greenhouse culture and pond culture. However, these two existing turtle culture models are pursuing production and pursuing the output of turtle farming per unit of water. They often use high-protein soft-shelled turtle compound feed and excessive bait. The use of high-density aquaculture results in the accumulation of residual bait and a large number of t...
