Problems solved by technology

Commonly used raw materials rich in ω-3PUFA mainly include fish oil and flaxseed by-products, both of which have their own advantages and disadvantages. Fish oil is rich in DHA, but it is easy to oxidize and has a special fishy smell, which affects the flavor of livestock and poultry products; Seeds are mainly rich in ALA, but the efficiency of transforming and depositing DHA in eggs is low, so it needs to be added in a high dose in the diet
At the same time, both are expensive, and the cost of the omega-3PUFA eggs produced increases, so it is imperative to find an alternative feed resource

Abstract

The invention discloses a diet for laying hens and application thereof. The diet for the laying hens contains a basal diet and a rubber seed oil; and according to the weight percentage, the adding amount of the rubber seed oil is 1-6%. The diet for the laying hens, disclosed by the embodiment of the invention, has the advantage that the DHA and EPA contents of eggs can be increased by adding an appropriate amount of rubber seed oil to the basal diet.

Description

technical field [0001] The invention relates to the technical field of poultry breeding, in particular to a diet for laying hens and an application thereof. Background technique [0002] ω-3PUFA (omega-3 fatty acids, mainly α-linolenic acid, EPA and DHA) can prevent and treat chronic diseases such as obesity, diabetes, cardiovascular and cerebrovascular diseases, and also play an important role in anti-cancer and immune regulation. In recent years, along with the raising of people's living standard, consumer's health consciousness is strengthened day by day, the food rich in omega-3PUFA (especially DHA) becomes the focus of attention of consumers and researchers. [0003] Eggs contain nutrients such as essential amino acids, fatty acids, vitamins and minerals needed in the human body, and are the daily necessities of consumers. Compared with expensive health care drugs, eggs rich in omega-3 PUFA are more favored by consumers. It has been reported that the composition and c...
