Feed for promoting intestinal development of juvenile black carp

Abstract

The invention belongs to the technical field of freshwater fish culture and especially relates to a feed for promoting intestinal development of juvenile black carp. The feed is prepared from the following raw materials: peanut meal, oat, corn, fresh pine needle, fresh alfalfa, fresh pumpkin vines and leaves, tomato, olive oil, fish meal, Chinese toon juice and myricetin. The feed is easy to digest and absorb, has high absorption conversion rate, and can be used to effectively increase villus height, goblet cell count and lymphocyte count of intestinal tract of juvenile black carp, reduce crypt depth of the intestinal tract, effectively promote rapid growth and perfection of intestinal tract of juvenile black carp, increase nutrient absorption area of the intestinal tract, raise enterocytematuration rate, enhance secretion absorption function, effectively improve the capability of absorbing nutrients, promote intestinal tract's capability of secreting mucoprotein, trefoil peptide andother substances, effectively protect the intestinal mucosa and promote intestinal health. Then, absorption utilization rate of nutrients is effectively increased so as to promote rapid and vigorous growth of juvenile black carp.

Description

technical field [0001] The invention belongs to the technical field of freshwater fish culture, in particular to a feed for promoting the intestinal tract development of herring juveniles. Background technique [0002] Herring is one of the "Four Major Fishes". The main breeding areas are Jiangsu, Anhui, Hubei and Hunan. The meat of herring is tender and delicious, and its protein content exceeds that of chicken. An important place, the development of intestinal tissue morphology has an important relationship with the growth of fish and the digestion and absorption of nutrients. However, in the process of breeding herrings, due to the slow development of the intestinal tract of herring juveniles, the development is not perfect, resulting in herring The absorption and transformation efficiency of juvenile fish to nutrients is low, thereby inhibiting the growth of juvenile herring; therefore, inventing a feed that promotes intestinal development of juvenile herring to solve th...

Problems solved by technology

[0002] Herring is one of the "Four Major Fishes". The main breeding areas are Jiangsu, Anhui, Hubei and Hunan. The meat of herring is tender and delicious, and its protein content exceeds that of chicken. It is the top grade among freshwater fish. An important place, the development of intestinal tissue morphology has an important relationship with the growth of fish and the digestion and absorption of nutrients. However, in the process of breeding herrings, due to the slow development of the intestinal tract of herring juveniles, the development is not perfect, resulting in herring Juvenile fish have low absorption and conversion efficiency of nutrients, which in turn inhibits the growth of herring juveniles; therefore, inventing a feed that promotes intestinal development of herring juveniles to solve the above problems can effectively promote the development of herring aquaculture
