Abstract

The invention discloses a feed additive for improving color and luster of animal carcass and use of the feed addtive. The feed additive comprises the following raw materials in mass percentage: 10-50%of a cortex magnoliae officinalis extract, 10-50% of a rhizoma curcumae longae extract, 10-50% of a rosemary extract and 10-50% of a macleaya cordata extract. Through scientific compatibility of thetraditional Chinese medicine extracts, the components generate a synergistic effect, absorption of carotenoid and other pigments in animal bodies is jointly promoted, and the color and luster of the animal carcass are improved.

Description

technical field [0001] The invention relates to the field of feed, in particular to a feed additive for improving the color of animal carcasses and an application thereof. Background technique [0002] Carotenoids are naturally yellow or orange and are effective natural colorants. Carotenoids are deposited in fat tissue in cattle, making the carcass yellow and affecting the quality of beef. In poultry, carotenoids are deposited in claws, beaks and subcutaneous fat to color them and improve the quality of poultry carcasses. In laying poultry, carotenoids are deposited in the yolk to make it yellow and improve egg quality. The body color of freshwater fish is mainly black and yellow. Melanin is synthesized by tyrosine under the action of tyrosinase. Bright body colors such as yellow and red are produced by carotenoids and lutein in the skin, Determined by the number and distribution of scale pigment cells. Therefore, the absorption, metabolism and distribution of carotenoi...
