Egg-laying poultry feed additive and egg-laying poultry feed

Abstract

The invention discloses an egg-laying poultry feed additive. The feed additive comprises microalgae powder of schizochytrium limacinum and also can comprise a microalgae powder composition of the schizochytrium limacinum and haematoculcus pluvialis. Furthermore, the invention discloses application of the egg-laying poultry feed additive to an egg-laying poultry feed. By adding the egg-laying poultry feed additive disclosed by the invention into a basal feed to prepare the egg-laying poultry feed for feeding poultry including chickens, ducks, gooses, quails, pigeons and the like, the contents of nutritional ingredients in poultry eggs are increased, especially the contents of the nutritional ingredients such as DHA (Docosahexaenoic Acid), EPA (Eicosapntemacnioc Acid) and astaxanthin in the eggs are increased, so the health-care and nutritional effects of the poultry eggs are greatly enhanced.

Description

technical field [0001] The invention relates to an egg-laying poultry feed additive for poultry breeding, belonging to the field of poultry breeding. Background technique [0002] Poultry eggs are one of the most common dietary foods in people's daily life. Eggs, duck eggs, goose eggs, quail eggs, pigeon eggs, especially eggs, are all common foods on people's tables. In order to improve the nutritional quality of poultry eggs, researchers in the breeding field have tried various feeding methods and feeds in recent years. Improved feeding methods usually improve the work and rest time of poultry through light and other conditions, thereby increasing their egg production rate It has little effect on the content of various nutrients in eggs; improving feed is by directly adding various trace elements and mineral salts to the feed, such as calcium carbonate, potassium iodide, trace element additives, amino acid additives, vitamin additives etc. This kind of feed ignores the phy...

Problems solved by technology

Existing studies have also shown that adding a large amount of these ingredients in the feed of laying poultry has little effect on the content of relevant nutrients in the laying eggs of poultry; According to research, this feed improvement method also does not take into account the biological characteristics of poultry, and blindly uses Chinese medicinal ingredients for human use on poultry, not only does not improve the quality of life and egg production of poultry, but poultry deaths due to physiological disorders and egg quality decline, irregular laying time and other problems, cannot be applied to large-scale farming

[0003] Considering the defects in the prior art comprehensively, the main reason is that the biological characteristics of poultry are not taken into account. Poultry, as a creature raised by humans for thousands of years, mainly uses plants or plant processed products as food. Its physiological structure, such as esophagus, intestinal tract, etc. The distribution of fluff on the inner wall, the shape of the mouth, and the evolution of the digestive system all correspond to plant-based feeds. Trying to absorb exogenous synthetic ingredients to poultry will only lead to either non-absorption, resulting in waste and increased breeding costs, or absorption with the poultry. Digestive and endocrine systems clash, leading to physiological abnormalities, disease and death
