Pelodiscus sinensis fodder containing low-protein fish meal added with methionine hydroxy analog-Ca

Abstract

The invention discloses a pelodiscus sinensis fodder containing low-protein fish meal added with methionine hydroxy analog-Ca. The raw material of the pelodiscus sinensis fodder comprises white fish meal, soy protein concentrate, fermented soybean meal, extruded soybean, chicken powder, squid powder, beer yeast, alpha-starch, gluten flour, zeolite powder, multivitamin, a compound mineral substance, choline chloride, glycine betaine, sodium dihydrogen phosphate and methionine hydroxy analog-Ca. According to the pelodiscus sinensis fodder disclosed by the invention, the methionine hydroxy analog-Ca is taken as the additive and is added into the pelodiscus sinensis fodder containing low-protein fish meal, so that the amino acid balance in the fodder is effectively kept, the growth promotion effect is excellent and the nutritional requirement for the growth of the pelodiscus sinensis is met. Compared with the traditional pelodiscus sinensis fodder taking fish meal as the main protein source, the pelodiscus sinensis fodder containing low-protein fish meal added with methionine hydroxy analog-Ca has the advantages that the protein content of the fodder is less than or equal to 44% and the additive amount of the fish meal is less than or equal to 26%. The fodder provided by the invention is capable of saving the dosage of the fish meal in the pelodiscus sinensis fodder and lowering the cost of the fodder, is ecological and environmentally friendly, and is capable of increasing the comprehensive breeding benefit.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to the field of compound feed for soft-shelled soft-shelled turtles at the juvenile stage, and relates to a low-protein, low-fishmeal soft-shelled soft-shelled soft-shelled turtle feed added with calcium hydroxymethionine. Background technique [0002] Soft-shelled soft-shelled turtle, commonly known as soft-shelled turtle, belongs to Reptiles, Turtles, Turtles, and Turtles. It has always been considered as a precious food and medicinal diet. Its meat is delicious and nutritious, and it is very popular among consumers at home and abroad. Chinese soft-shelled turtle is an important aquaculture species in my country. The breeding area covers more than 20 provinces (cities, districts) in China. The main production areas are Zhejiang, Guangdong, Jiangsu, Hubei and other places. In 2013, the national output reached 344,000 tons. An industry that integrates seedlings, breeding, feed, medicine...

Problems solved by technology

However, excessive feed protein will not be effectively converted into body protein, but will be consumed as an energy substance. In the process of converting into energy, energy will be consumed due to conversion and decomposition, resulting in protein waste; in addition, fish meal is used as Its main feed protein raw material, its resources are increasingly scarce, and the market price continues to be at a high level. Adding a high proportion will easily cause pollution to the breeding water body, which is not in line with the sustainable development of the environment-friendly soft-shelled turtle breeding industry

[0004] Partial replacement of fishmeal in Chinese soft-shelled turtle feed with soybean meal plant protein, the main obstacle is the imbalance of essential amino acids. Adding a high proportion will lead to the lack of essential amino acid methionine in the feed, and the efficiency of feed utilization will decrease, affecting normal growth.
