Method of fumigation treatment on breeding house of scatter-fed black pigs

Abstract

The invention provides a method of fumigation treatment on a breading house of scatter-fed black pigs, and relates to the field of black pig breeding. The method comprises the steps that 25 parts by dry weight of asiatic wormwood, 3 parts by dry weight of radix gentianae, 5 parts by weight of radix angelicae dahuricae stems, 15 parts by weight of charcoal, 5-8 parts of loess which are dried in the sun are selected to be made into a fuel composition, the fuel composition is put into a fire pan and lighted to be fumigated by being put into a cave, when fumigation is conducted, the opening of the cave is sealed, the fire pan is connected with a rope which leads to the outside of the cave, the fire pan is made to move forwards by 20-30 cm by pulling the rope every five minutes, and the fire pan only needs to move to the cave for one time. The fumigation is conducted on the interior of the cave through hot flue gas produced by the fuel composition in the fire pan, germs on the surface of the cave or 5 cm deep inside the soil can be killed, mice and ants can be expelled, and the mice and the ants are prevented from opening a cavity to make a nest near the cave. For the black pigs in the cave, the functions of clearing heat, eliminating dampness and purging liver and gall fire are achieved, and dampness and chilliness are prevented from entering the bodies of the black pigs.

Description

Technical field [0001] The invention relates to the field of black pig breeding, in particular to a method for building a free-range black pig pen. Background technique [0002] Pork is one of the common foods in life. Pork is very popular in the market. However, the existing commercial pigs are generally raised in captivity, with short growth cycles and fast growth rates. They use hormones for commercial pigs, and the meat quality is not delicious. There are toxic ingredients remaining in the body, endangering the health of consumers. Summary of the invention [0003] The purpose of the present invention is to provide a construction method of free-range black pig pens to solve the above technical problems. The free-range black pig house provides a better free-range environment for black pigs. The black pigs can fully contact the natural environment, have a wide range of activities, have good physical fitness, strong resistance, basically no medicine, and pork quality high. [00...
