Abstract

The invention relates to a chicken feed additive based on a ginkgo biloba leaf extract and an application of the chicken feed additive. The chicken feed additive comprises the following components inpercentage by mass: 50-80% of a ginkgo biloba leaf extract, 10-30% of fucoidin sulfate and 10-30% of ginseng leaf extract, wherein the ginkgo leaf extract contains 10% or more of total polyphenol and10% or more of total polysaccharide, wherein the fucoidin sulfate contains 5% or more of L-fucose, and the ginseng leaf extract contains 20% or more of ginseng total saponins. Through the synergisticeffect of the components of the chicken feed additive, the carcass color of chicken is improved on the premise of ensuring the health and nutrition of chickens. The invention further provides an application of the chicken feed additive based on the ginkgo biloba leaf extract in chicken feed.

Description

Technical field [0001] The invention relates to the field of chicken feed, in particular to a chicken feed additive based on Ginkgo biloba extract and its application. Background technique [0002] The yellow color in chicken is mainly derived from carotenoid pigments. Chickens cannot synthesize carotenoids, and can only convert different types of carotenoids in the body or make them participate in body metabolism. The digestive tract of poultry only absorbs lutein, and yellow pigments from different sources have different biological utilization rates. Researchers studied the utilization of some carotenoids in broiler chickens by isotope tracing method. The results showed that the proportion of pigments that actually act as yellow deposits in the skin in the diet is very low, even if the same yellow pigment is used in broilers The coloring efficiency of the skin may still be quite different. For example, the yellow pigment deposition in broilers is more complicated. The first ...
