BRD is multifactorial, meaning that it arises from various factors working in combination. Respiratory pathogens, such as Mannheimia haemolytica, Pasteurella multocida, and Histophilus somni, often cause secondary infections following a viral infection, such as infectious bovine rhinotracheitis (IBR) or bovine respiratory syncytial virus (BRSV). Environmental factors like overcrowding, poor ventilation, sudden temperature changes, and inadequate nutrition can weaken the immune system of cattle, making them more susceptible to pneumonia.

In conclusion, while antibiotics play a vital role in managing respiratory infections in chickens, their use presents significant challenges, particularly concerning antibiotic resistance. The poultry industry must balance the immediate need for effective treatments with the long-term health of poultry and public safety. By investing in alternative strategies and adhering to regulatory guidelines, farmers can work towards more sustainable practices that protect both their livestock and the broader community from the dangers of antibiotic overuse. Fostering a holistic approach to poultry health will be critical in ensuring the industry's future while prioritizing animal welfare and public health.

  • An oil seal is a type of mechanical seal used to prevent the leakage of oil from machinery components. The dimensions of an oil seal are usually specified in terms of its inner diameter, outer diameter, and thickness. For example, a 38x52x7 oil seal has an inner diameter of 38mm, an outer diameter of 52mm, and a thickness of 7mm.


  • In addition, PTFE oil seals have a low coefficient of friction, which helps to reduce the wear and tear on the sealing surfaces. This not only prolongs the life of the seals but also improves the overall efficiency of the machinery they are used in.

  • No.
  • Regular inspection and maintenance of valve cover gaskets, head gaskets, and spark plugs are essential to identify signs of wear, damage, or deterioration. Proper replacement of worn or damaged components is crucial for maintaining the efficiency and reliability of the engine. Adhering to recommended service intervals and using high-quality replacement components are essential for optimizing the performance and longevity of the engine's critical components.

  • Motor oils typically include a few additives which can make up between 5% and 30% of the oil. These additives help enhance the performance of the oil. Motor oils can include the following additives:

  • Oil seals are commonly used in engines, gearboxes, and other rotating machinery to prevent the leakage of oil from shafts and bearings. They are typically made from rubber or elastomeric materials that are resistant to oil and heat. The seal is installed in a housing or bore that is larger than the shaft, and it is pressed against the shaft to create a tight seal.
