There are many factors that determine the profitability of pigs, variety, nutrition, environment, management, disease, market, etc. Whether a farm can continue and develop healthily is not to see which link is best, but to see that the link is doing poorly. The poor link will determine the success or failure of pig farming. The following author introduces two aspects of the farm (environment and disinfection).
surroundings
temperature. Excessively low temperatures in the pens affected pig feed consumption and weight gain. The suitable temperature range for pig rearing depends on a variety of factors such as the pig's breed, age, physiological stage, and feeding conditions. For example, the temperature of a newborn piglet should be controlled within 32°C-35°C during one week, then decreased by 2°C every week, the temperature of the nursery is controlled at 22°C-27°C, the temperature of the finishing pig house is maintained at 17°C-20°C, and the temperature of the delivery room cannot be maintained. More than 25 °C.
humidity. The high humidity in the pens reduces the disease resistance of the pigs and has a greater impact on the piglets. At the same time, the high humidity environment is relatively conducive to the growth and reproduction of pathogenic microorganisms, and the frequency of pigs suffering from warts, eczema, and respiratory diseases increases. In some pig farms with poor breeding conditions, in order to prevent cold in winter, they are often covered with plastic sheeting at the top, which is very unfavorable for the pigs, especially when the pigs do not pay attention to ventilation. improve. Studies have shown that pigs have the best fattening effect at temperatures ranging from 11°C to 23°C and relative humidity from 50% to 80%.
ventilation. Excessive levels of harmful gases in the enclosures are closely related to intestinal digestion, especially in the case of confinement in winter. The harmful gas in piggery, including ammonia, hydrogen sulfide, carbon dioxide, methane, etc., is not only unpleasant and irritating (has a strong corrosive effect on the pig's eyes and respiratory mucosa), but also provides fire protection for pig farms. It's a lot of pressure. Pigs in this environment have a much higher chance of developing respiratory diseases. Ventilation and ventilation should be arranged when the pigs are most active in eating and eating. Normally, the timing fan is switched on and off. The extensive use of Oerlikon of Hebei Weiyuan Animal Pharmaceutical Co., Ltd. in pig farms will not only improve the function of the intestine, reduce the slag in the feces, but also increase the resistance of the pigs, advance the slaughter, thereby improving the fattening efficiency and increasing the breeding. benefit.
density. To reasonably control the rearing density, the difference in piglets weaned in the same batch should not exceed one week, and it is best to use a nest to avoid infection among piglets that reduce different immune status.
disinfection
Acid and alkaline disinfectants. It can dissolve proteins or hydrolyze the proteins and nucleic acids of pathogenic microorganisms, destroy the enzyme system and cell structure, and display a strong killing effect on pathogenic microorganisms, viruses, bacteria and their spores. However, since acids and bases can corrode organic tissues, they are also corrosive to humans, animals, wood, and metals, which greatly limits the use of these disinfectants. At present, the most commonly used pig farms are fiery alkali, which can be used as doorway disinfection pools, staff access pads and empty circle homes disinfection, can not contact the skin or mucous membranes, disabled with pig disinfection, the recommended concentration of empty circle disinfection is 2% - 5%.
Aldehyde disinfectants. Aldehyde disinfectants include formaldehyde and glutaraldehyde. They can bind to the amino group of proteins to denature proteins, coagulate proteins and dissolve lipids. They have a powerful broad-spectrum bactericidal effect on pathogenic microorganisms, as well as bacterial propagules, spores, and fungi. Viruses are all effective. Formaldehyde gas is extremely toxic to pigs and humans and is not suitable for the disinfection of pigs. Glutaraldehyde is widely used, but it has some irritating effects. It must be careful not to contact the skin and mucous membranes.
Phenolic disinfectants. Including phenol, coal phenol (L-Zolves), and complex phenols, etc., can make bacteria protein denaturation, precipitation and bactericidal effect. Phenol, Lysol, etc., due to its general bactericidal power and high toxicity, have long been used for the disinfection of pig farms.
Chlorine disinfectant. Chlorine-containing disinfectants have a high affinity for the bacteria's protoplasm and other structural components, and are easily infiltrated into the cells and combined with the amino or other groups of the original protein of the bacteria to decompose or lose their functions and exhibit bactericidal action. Chlorine disinfectants dissolved in water to form hypochlorous acid and exhibit bactericidal action, but the stability of bleaching powder is poor, and the decomposition of sunlight, heat, humidity and other factors accelerates, and the content of available chlorine in storage will continue to decline, thereby affecting its in water. Effective disinfection concentration; 84 disinfectant is a sodium hypochlorite-based disinfectant, widely used by hospitals, families, farms, etc., but corrosive and irritant, more diluted for the toilet, feces and other disinfection.
Halogen disinfectants. Povidone iodine solution can quickly and completely kill a variety of bacteria, fungi, viruses and other pathogens in skin mucous membranes and environmental housing. Because it is non-irritating and has good disinfection effect, it can be used for various inflammations, skin infections, and mucosal surgery. Wounds, etc., can also be used to sterilize pig sheds and the environment. It is one of the ideal disinfection products for pig farms. Jinweikang of Weiyuan, Hebei has the characteristics of high concentration, strong penetrating power, and good stability. When the foot-and-mouth disease develops, it directly smears the extremities of the extremities, which can quickly relieve and relieve pain, promote wound healing, and restore appetite to sick pigs.
Other disinfectants. Alcohols such as alcohol, hydrogen peroxide, and potassium permanganate are often used as surface or local disinfection and cannot be used for environmental disinfection.
