Abstract

The invention discloses a feed additive for necrotic enteritis of livestock and poultry. The invention provides new application of round-leaf grape pomace, cardamom, radix aucklandiae, bagasse, radix sophorae flavescentis and synanthrin. The invention also provides a preparation method of the livestock and poultry feed and the feed additive. Animal feeding tests prove that the feed additive not only can reduce the death rate of broilers with necrotic enteritis and intestinal lesions of the broilers with necrotic enteritis and effectively improve the necrotic enteritis of the broilers, but also can increase the average daily feed intake and the final body weight, reduce the content of dextran in serum of the broilers with necrotic enteritis and increase the content of IGF-I and EGF in the serum of the broilers with necrotic enteritis. Therefore, growth performance of the animals is further promoted, and the feed additive has a good popularization and application prospect in the aspects of promoting the growth performance and intestinal development of the broilers with necrotic enteritis.

Description

technical field [0001] The invention belongs to the technical field of improving necrotic enteritis of livestock and poultry, and in particular relates to a feed additive for necrotic enteritis of livestock and poultry and a preparation method thereof. Background technique [0002] It is estimated that necrotic enteritis can cause an economic loss of about 2 billion US dollars per year. Necrotic enteritis (NE, necrotic enteritis) has become a problem that plagues the broiler industry all over the world, and it has also become a major problem in the poultry industry that has attracted much attention. [0003] Necrotic enteritis is caused by toxins produced by Clostridium perfringens types A or C, and the clinical presentation of necrotic enteritis varies markedly, ranging from reduced productivity to the occurrence of sudden and high mortality as well as severe dyspepsia, Growth arrest is the main feature, which usually occurs at 2 to 6 weeks of age. The early symptoms of ne...
