Problems solved by technology

Due to the low yield of early asparagus (Gracilaria lemaneiformis), domestic research on asparagus and its extracts started late, but with the development of planting technology and planting scale, asparagus has now become one of the four major economic As one of the cultivated seaweeds, the cost of asparagus extract is gradually decreasing, so the development of new uses of asparagus polysaccharides has become one of the important problems that the industry wants to solve

Abstract

The invention belongs to the technical field of feed processing, and particularly relates to a poultry feed added with asparagus polysaccharide and tannic acid. The feed is composed of a basal feed and an effective component, wherein the effective component is asparagus polysaccharide or a composition of asparagus polysaccharide and tannic acid; the addition amount of the asparagus polysaccharide in the feed is 0.05-0.15%; and the weight ratio of the asparagus polysaccharide to the tannic acid is (5-15): (1-5). The feed provided by the invention can enhance the immunoglobulin level of broilers, lower the inflammatory factor level and enhance the immunological performance of the broilers.

Description

technical field [0001] The invention belongs to the technical field of feed processing, in particular to a poultry feed added with asparagus polysaccharide and tannic acid. Background technique [0002] In recent years, people's living standards have been increasing day by day, and the per capita consumption of meat and eggs has steadily increased. Broiler chicken farming occupies a considerable proportion of my country's current animal husbandry production. Especially since 2018, the African swine fever has been raging, the supply of live pigs has dropped rapidly, and the price of pork has soared. People's demand for chicken is increasing. However, in the breeding process, in order to reduce costs, enterprises adopt high-density and intensive feeding methods, which causes the physiological and environmental pressure of broilers to rise sharply, and diseases frequently occur. The current routine practice is to add a small amount of antibiotics to broiler diets to prevent co...
