Crispy tilapia formula feed and preparation method thereof

Abstract

The invention discloses a crispy tilapia formula feed and a preparation method thereof. The feed is prepared from the following raw materials in parts by weight: 15 to 20 parts of fish meal, 15 to 20 parts of soybean meal, 40 to 50 parts of broad beans, 10 to 15 parts of rapeseed meal, 1 to 5 parts of fish oil, 1 to 5 parts of soybean oil, 0.5 to 1.5 parts of hydrolyzed yolk powder, 0.2 to 1 part of monocalcium phosphate, 0.2 to 1 part of choline chloride, 0.3 to 0.7 part of morinda citrifolia pulp, 0.2 to 0.6 part of vitamin C and 0.1 to 0.3 part of compound multivitamins. The feed is prepared by weighing, premixing, mixing, tempering, forming and granulation. The feed effectively meets the comprehensive requirements of tilapia on nutrient substances at the growth stage, and the tilapia meat becomes tight, crispy and tasty, cannot easily boil out, cannot be easily broken through being pulled after being cut into shredded fish; and additionally, the taste is delicious, and the flavor is unique. Meanwhile, the feed has a relatively strong shape-preserving property, the food calling property of the feed is enhanced, and the utilization rate of the feed is effectively improved.

Description

technical field [0001] The invention relates to a feed for aquatic animals, in particular to a formula feed for embrittled tilapia. Background technique [0002] Tilapia (Oreochromis pp) belongs to Chordate Phylum, Vertebrate Subphylum, Fish Class, Perciformes, Squididae, Tilapia genus in animal classification, and its body size is similar to crucian carp. Because it is native to the inland waters of Africa, it is also called African crucian carp. The body length of tilapia can reach more than 20cm. Mouth front, body side flat, back taupe or dark brown, dorsal fin with well-developed spines, anal fin with three spines, caudal fin truncated, lateral line interrupted, body covered with ctenoid scales. Tilapia generally inhabits the bottom of the water, and when the water temperature changes, it changes the habitat water layer. Tilapia has the advantages of low oxygen resistance, fast growth, high yield, less disease, and strong reproductive ability. It is an important aquatic...

Problems solved by technology

Embrittlement farming still uses soaked or germinated broad beans as the main raw material. Feeding soaked or germinated broad beans is far less convenient than feed, and the cost is high, which is not conducive to the expansion of breeding scale.
