Causes of "fake hens" and preventive measures

In poultry farming, some layer hen producers may face a common issue: the replacement chickens appear healthy, with good weight and uniformity, meeting all the expected standards. However, during the egg-laying phase, these hens fail to reach their peak production. Upon close inspection, it is discovered that some of them are completely unable to lay eggs. These birds are often referred to as "female hens" or "non-laying hens." The underlying cause is usually an infection with infectious bronchitis virus (IBV) in the first 1-2 weeks of life. This early infection can lead to improper development of the oviduct or intermittent growth, which remains undetectable until the laying period begins. At this stage, antibiotics offer no effective treatment. The main causes behind such cases include: 1. Infection with the infectious bronchitis virus within the first 1-2 weeks of age. 2. Failure to vaccinate against infectious bronchitis. 3. Poor control of the internal and external environment of the chicken house within two weeks before the chicks arrive. 4. Secondary infections caused by *E. coli* or mycotoxins. 5. Presence of immunosuppressive diseases, leading to ineffective immune response against IBV. 6. Improper vaccination procedures for the local strain of infectious bronchitis. To manage and prevent this issue, several strategies should be implemented: 1. Ensure proper and timely vaccination programs. Vaccination should begin immediately after the chicks arrive at the farm to build mucosal immunity. 2. Maintain strict hygiene and disinfection practices in the chicken house before and after the chicks are introduced. Disinfect both the inside and outside of the house daily to reduce the viral load. 3. Provide optimal care for chicks during the critical first two weeks of life, including stable temperature and reduced stress. 4. Prevent secondary diseases like mycoplasmosis, *E. coli*, and mycotoxin poisoning, as these can weaken the immune system and increase susceptibility to IBV. Key points for effective infectious bronchitis vaccination: 1. **Immune Principle**: As soon as the chicks arrive on the farm, live vaccines should be administered to establish local mucosal immunity. 2. **Vaccine Selection**: Due to the high variability of IBV serotypes and limited cross-protection between them, it's important to use multiple strains. A typical schedule includes: - First vaccination (day 1): H120 or MA5 strain. - Second vaccination (day 7): H120 + 2880 strain. - Third vaccination (day 17): Live vaccine (Mass and Coon strains) combined with an inactivated vaccine (New branch oil emulsion). 3. **Vaccination Method**: Common methods include nasal drops and eye inoculation. For nasal administration, block one nostril and inject the vaccine into the other. For eye inoculation, hold the chicken sideways and drop one drop into the open eye. Allow the vaccine to absorb before releasing the bird. By following these steps, farmers can significantly reduce the occurrence of non-laying hens due to infectious bronchitis and improve overall flock performance.

Neck Massager

Whether it's from sleeping weird, working out too hard, or sitting hunched over for hours staring at your computer, most of us have dealt with kinks in our necks from time to time. According to a peer-reviewed article from Marco Funiciello and Zinovy Meyler, Doctors of Osteopathic Medicine, one of the best ways to soothe aches and pains in your neck is through massage therapy.
