Summer heatstroke in pig farms must be "targeted"
Boars are fed twice a day, and green feed or thinner is added at noon. Breeding and exercise are performed in the morning and at night. Do not spray water or spray cold water immediately after mating. From 1 pm to 3 pm every day, water is sprayed on the pigs and the ground once, and the light is reduced to 8 to 10 hours. If the number of breedings is small, the amount of fine feed should be reduced to prevent over-fertilization and poor libido. Pregnant sows avoid breeding during high temperature season breeding. Sows in the pre-pregnancy period (0 to 84 days) should be dominated by green coarse materials, with appropriate concentrates, to reduce the stocking density, and raise 2 to 3 pigs per lap. In the second trimester of pregnancy and during the lactation period, the pig should concentrate on the raw material to match the green material. The coarse material can be fed without feeding, and the feed can be fed 3 times a day. Add 1% to 1.5% baking soda, 0.3% salt. The sow's summer delivery room should be equipped with a well-ventilated litter box with shading facilities. The production mothers should reduce the concentrates 2 to 3 days before the onset of labor, and feed more green materials. The ratio of bran in the concentrates should be increased. The purpose of the bowel against constipation is to feed the bran warm brine once after the piglets have been produced. The commodity pigs are difficult to raise during the high temperature season and often appear to fall down and do not eat, affecting growth. Generally, fat pigs are sold before the high temperature season has passed. If they are not for sale, the stocking density should be reduced, and a few heads per lap should be kept. Each pig occupies a circle area of ​​1 to 1.2 square meters. Water spray cooling, feed sooner or later, at noon plus green feed or thin material, the material plus sodium bicarbonate 1.5%, salt 0.3%. Suckling piglets and piglets prefer lying on the wet ground, pay attention to changes in the weather to prevent cold pulling or diarrhea. Keep the dough dry, clean drinking water, often disinfected. Prevention can be used per kilogram of material plus 120 milligrams of oxytetracycline for several days and several days of treatment, with oxytetracycline 200 milligrams per kilogram.
The antibacterial or bactericidal effect of antibiotics and other antibacterial agents is mainly aimed at killing the mechanism of "there is bacteria but not by humans (or other animals and plants)". It contains four major mechanisms of action, namely: inhibiting bacterial cell wall synthesis and enhancing bacterial cell membrane permeability Sex, interfere with bacterial protein synthesis and inhibit bacterial nucleic acid replication and transcription.

Antibiotic refers to a class of secondary metabolites produced by microorganisms (including bacteria, fungi, actinomycetes) or higher animals and plants that have anti-pathogens or other activities in the life process and can interfere with the development of other living cells. Chemical material. Antibiotics commonly used in clinic are extracts from microbial culture fluids and chemically synthesized or semi-synthetic compounds. [1]
