Growing-finishing pig compound feed for reducing pigsty ammonia concentration and production method thereof

Abstract

The invention relates to a growing-finishing pig compound feed for reducing pigsty ammonia concentration and a production method thereof, belonging to the technical field of livestock breeding. The compound feed comprises the following raw materials in parts by weight: 550-700 parts of corn, 50-150 parts of soybean meal, 20-100 parts of DDGS, 10-100 parts of rice ran, 10-80 parts of corn bran, 50-180 parts of beet pulp, 5-15 parts of vitamin premix, 5-15 parts of microelement premix, 3-5 parts of table salt, 1-5 parts of calcium hydrogen phosphate, 6-20 parts of calcium sulfate, 0.5-1.5 parts of choline, 0.5-10 parts of lysine, 0.5-10 parts of methionine, 0.5-10 parts of threonine, 0.5-5 parts of tryptophan, 0.1-0.3 part of yucca extract, 0.2-2 parts of protease preparation, 0.2-2 parts of feeding probiotics and 0-1 part of ethoxyquinoline. In the invention, regarding current breeding environment (particularly the closed environment in winter) and the nutrition level of commercial growing-finishing pigs, the release ability of manure ammonia in the pigsty is reduced by a nutrition regulation method, and a functional compound feed is provided for the growing-finishing pigs.

Description

technical field [0001] The invention relates to a compound feed for growing and finishing pigs and a production method thereof. More specifically, the invention relates to a compound feed for growing and finishing pigs which reduces the ammonia concentration in a pig house and a production method thereof, belonging to the technical field of livestock and poultry breeding. Background technique [0002] Ammonia (NH 3 ), a colorless gas with a strong pungent odor, easily soluble in water, and weakly alkaline, easily reacting with H + Form NH 4 + , is irritating to animal mucous membranes, can cause tearing, burning pain in the eyes, inflammation of the cornea and conjunctiva, irritates the respiratory tract, causes or aggravates respiratory diseases (including atrophic rhinitis); ammonia gas enters the blood and reduces the amount of dissolved oxygen in the blood, reducing the amount of livestock and poultry Long-term exposure to 10-15mg / kg ammonia concentration will signifi...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve the problem of the existing breeding environment, especially the pens in the closed environment in winter, where the pressure of ammonia gas is still severe, which seriously reduces the health level of live pigs, is in a sub-health state for a long time, and also threatens the health of the breeders. The problem is to provide a compound feed for growing and
