How can the poultry industry prevent cold damage? The province's poultry industry technology system proposed the following countermeasures.
Increase nutrient-strength shelters. Improve the energy value of livestock and poultry diet and the level of B vitamins, and ensure that livestock and poultry meet the demand for additional heat due to the drop in ambient temperature. Such as increasing the corn, rice, wheat and other cereals, raw materials, and the amount of feed grease; moderately increase the amount of bran, rice bran, high-quality grass powder, or add B group vitamins additives. Note that while increasing the amount of raw materials for wheat, pay attention to adding the appropriate special enzyme preparation at the same time to ensure the utilization of non-starch polysaccharides.
By means of facilities such as electric heating or biomass boilers, raising the temperature inside the house and increasing the temperature of the drinking water to a warm state aim to reduce the energy consumption of the feed used to maintain the body temperature, increase the efficiency of converting the energy value of the diet to livestock and poultry products, and reduce the feed cost.
To prevent heavy snow from squeezing the sheds, the pillars can be added and protected at intervals of 5 meters below the roof beams; the shed area can be cleaned in time; the temperature inside the sheds can be increased to promote the melting of ice and snow. In the context of reducing the circulation of air, in particular, attention should be paid to the occurrence of carbon monoxide poisoning caused by heating in the house. In the case of avoiding draughts, the amount of air exchanged can be properly maintained to ensure the safety of breeders and poultry.
Key technologies for layer chicken breeding in severe cold weather. Reinforce the shed and remove the snow from the roof. To comprehensively inspect and reinforce infrastructure and equipment such as hen houses and hydropower, special attention should be paid to investigating old chicken houses with hidden dangers and timely transferring chickens to avoid serious collapse accidents. At the same time, electricity safety should be taken into consideration to prevent poultry from being electrocuted due to the collapse of the shed and breaking the wire.
Get enough feed and fuel. In the case of low temperatures, the proportion of energy components in the feed can be appropriately increased. For example, 10%-20% of corn can be added on the basis of the original, and at the same time, the amount of feed should be appropriately increased according to the weight. When the temperature drops by 3°C, the feed amount per bird will increase by about 5 grams per day, after the cold has passed. Then gradually return to the original feed level. Prepare enough feed and fuel to keep abreast of weather and traffic information, Supplement feed and fuel, and ensure supply.
Strengthen disease prevention and control. In particular, it is necessary to strengthen immunity against bird flu, infectious bronchitis, Newcastle disease and other diseases. Chickens that died as a result of the disaster should be treated as harmless as soon as possible to prevent the spread of disease.
Critical technology for broiler breeding in severe cold weather. Reinforce the hen house and remove the snow on the roof in time to prevent the henhouse from collapsing and avoiding more harm to people and livestock. Strengthen insulation measures, especially local insulation, such as adding heat lamps or coal stoves to the chicks to prevent galling of chickens; Minimize the amount of outdoor exercise for broiler chickens; strengthen sealing measures for breeders, and pay attention to proper ventilation and fire safety . The broiler is thickened with litter, especially to keep the litter dry.
Timely immunity. Closely monitor the dynamics of chickens and effectively prevent the occurrence of winter communicable diseases such as infectious bronchitis, bird flu and Newcastle disease. Strengthen the biosafety measures, especially the sanitation and sanitation around the house, to prevent the intrusion of bacteria and viruses.
