Abstract

The invention belongs to the technical field of feed additives, and in particular relates to a live pig feed additive and a preparation method thereof. The live pig feed additive consists of the following components in parts by weight: 30 to 50 parts of moutan bark extracts, 30 to 50 parts of mangnolia officinalis extracts and 90 to 100 parts of carriers. The live pig feed additive prepared by the method can increase the daily intake of live pigs, increase the daily weight increasing quantity, improve feed conversion rate, reduce diarrhea rate, increase survival rate and improve production benefit.

Description

【Technical field】 [0001] The invention relates to the technical field of feed additives, in particular to a pig feed additive and a preparation method thereof. 【Background technique】 [0002] Pig farming is the main industry of animal husbandry in my country. In 2001, my country had 457 million live pigs and 549 million slaughtered pigs, accounting for 51.8% and 46.8% of the world's stock and slaughter respectively. The proportion accounted for 66.1%. my country is not only a big pig raising country but also a big pork consuming country. The proportion of pork consumption is nearly 28 percentage points higher than the world average. [0003] Since the early 1990s, after my country's animal products entered the international market, many products have been returned or destroyed by many countries due to drug residues. Broiler chickens exported to Japan were returned one after another due to excessive residues of "gram ball powder" in chicken meat, resulting in export obstruct...
