Fallen Stock in Poultry and Livestock Production

Fallen stock refers to animals that have died on a farm due to disease, injury, age, or other reasons and have not been slaughtered for human consumption. Managing fallen stock is a critical aspect of modern poultry and livestock production because improper handling can lead to environmental pollution, disease outbreaks, and violations of legal and ethical regulations.

Below, I will explain examples of fallen stock specifically in the context of poultry and livestock production and the associated methods of managing them efficiently.

Examples of Fallen Stock in Poultry and Livestock Production

In Poultry Production

  1. Chicks Mortality:

    • Newly hatched chicks sometimes suffer from congenital deformities or weakness, leading to early deaths.
    • Example: A poultry farm incubates 10,000 eggs, but 200 chicks die within the first week due to poor hatchery conditions or disease.

  2. Broiler Chicken Deaths:

    • Broiler chickens raised for meat production might die due to heat stress, overcrowding, or respiratory infections like avian influenza.
    • Example: A flock of 5,000 broilers suffers losses of 50 chickens during an extreme heatwave.

  3. Layer Hens Mortality:

    • Egg-laying hens may succumb to diseases like Newcastle disease, malnutrition, or age-related issues like decreased egg production.
    • Example: A farmer loses 30 laying hens out of a flock of 1,000 due to calcium deficiency, causing eggshell deformities and internal complications.

  4. Sudden Death Syndrome (SDS):

    • Broilers, especially males, can experience SDS, where they die suddenly without noticeable symptoms. This is common in fast-growing birds.
    • Example: 20 broiler chickens die unexpectedly in a single night due to SDS.

In Livestock Production

  1. Calf Mortality in Cattle Farms:

    • Young calves may die from digestive diseases like diarrhea caused by E. coli or dehydration.
    • Example: A dairy farmer loses 5 out of 100 newborn calves due to bacterial infection.

  2. Adult Cattle Death from Disease:

    • Adult cattle can fall victim to foot-and-mouth disease (FMD) or bovine tuberculosis (TB).
    • Example: A rancher loses 3 cows out of a herd of 200 due to bovine TB.

  3. Sheep Mortality:

    • Sheep can succumb to infections such as liver fluke, malnutrition, or predator attacks.
    • Example: Heavy rainfall leads to a liver fluke outbreak, killing 10 sheep in a flock of 300.

  4. Pig Mortality:

    • Pigs reared for pork face risks from diseases like African swine fever (ASF) or dietary imbalances resulting in sudden death.
    • Example: A swine farm loses 15 pigs following an ASF virus outbreak.

  5. Goat Mortality:

    • Goats are vulnerable to parasitic infections, poor feed quality, and harsh climatic conditions.
    • Example: A farmer loses 7 goats during a prolonged drought season because of malnourishment and lack of water.

  6. Horse Deaths in Farming:

    • Horses used in draft farming or as part of agritourism operations may die due to injuries, colic, or joint diseases.
    • Example: A farmer’s aging draft horse dies of an irreversible case of colic after several years of service.

Causes of Fallen Stock in Poultry and Livestock

Fallen stock arises due to several causes, which may include natural factors, disease outbreaks, or human-related mismanagement. Here are some usual reasons:

  1. Poor Biosecurity Measures:

    • Lack of proper sanitization and biosecurity protocols allows infectious diseases to spread rapidly.

  2. Nutritional Deficiencies:

    • Inadequate diets lacking essential vitamins and minerals result in weakened immunity and severe health problems.

  3. Environmental Stress:

    • Extreme weather conditions, such as heatwaves or freezing temperatures, often lead to fatalities.

  4. Overcrowding:

    • High population density in confined spaces increases stress, aggression, and the potential for disease outbreaks.

  5. Insufficient Veterinary Care:

    • Delayed or inadequate treatment of illnesses can result in preventable deaths.

  6. Predation:

    • Predator attacks, especially on unmanaged free-range animals like poultry and sheep, are a common cause.

Management of Fallen Stock

The effective handling and disposal of fallen stock are essential in poultry and livestock farming to prevent environmental contamination, protect animal health, and comply with local regulations.

Steps for Managing Fallen Stock

  1. Immediate Removal:

    • Fallen stock must be removed from enclosures or pastures promptly to prevent the spread of disease.

  2. Reporting to Authorities:

    • Some regions require authorities to be notified of deaths caused by notifiable diseases like foot-and-mouth disease.

  3. Proper Storage Before Disposal:

    • Dead animals should be stored in leak-proof, vermin-proof sealed bags or containers.

  4. Safe Disposal:

    • Approved disposal methods vary by region and include:
      • Rendering: Turning dead animals into by-products like meat-and-bone meal or tallow.
      • Incineration: Burning the carcasses at high temperatures in approved facilities.
      • Composting: Composting fallen stock in permitted agricultural settings (usually for small animals like poultry).
      • Burial: Only authorized if the farm lacks access to other disposal facilities, and strict environmental guidelines are followed.

  5. Disinfection of Areas:

    • Enclosures where the fallen stock was discovered must be disinfected thoroughly.

  6. Continuous Monitoring and Prevention:

    • Routine health checks and vaccinations are essential to reduce future mortality rates.

  7. Engaging Professionals:

    • Farmers may contact licensed fallen stock collectors who are skilled and authorized in managing dead animals.

Legal and Ethical Considerations

  1. Government Regulations:

    • Many countries, such as the U.S. and EU nations, enforce specific laws on the disposal of fallen stock. For instance:
      • European Union: The Animal By-Products Regulations (ABPR) mandates how fallen stock should be collected and disposed of safely.
      • U.S.A: The USDA (United States Department of Agriculture) provides guidelines for proper carcass disposal.

  2. Environmental Considerations:

    • Improper disposal methods, such as dumping dead animals in open fields or water bodies, can lead to soil and water contamination.

  3. Ethical Responsibility:

    • Farmers must prioritize humane treatment and prevent unnecessary animal suffering that could lead to preventable deaths.

Examples of Fallen Stock Control Programs

1. National Fallen Stock Scheme (UK):

  • This program, created in the UK, helps farmers manage fallen stock by providing access to licensed collectors and affordable disposal solutions.

2. Biosafety Programs:

  • Countries affected by diseases like bird flu encourage biosecurity protocols to prevent and manage high fatalities in poultry farms.

3. Disease Surveillance Systems:

  • Governments often set up disease surveillance to predict outbreaks and assist farmers in reducing stock loss.

Conclusion

Fallen stock management is an integral part of running a poultry or livestock production business. Proper care, disease prevention, and compliance with legal and ethical guidelines minimize losses and prevent larger issues like environmental degradation or disease transmission. Farmers must remain vigilant for signs of illness or stress in their animals to ensure swift remedial action.
