Bone meal is a good source of calcium and phosphorus, which are essential for strong root systems and robust plant growth. While it is commonly used as a fertilizer, some people wonder if it can be added to chicken feed. After all, chickens are omnivores and can benefit from the nutrients in bone meal. However, there are some concerns about the use of bone meal in animal feed due to the mad cow disease scare in Europe, where infected animals were rendered into bone meal and fed to others, spreading the disease. Nevertheless, some people continue to use bone meal as a supplement in their chicken feed, especially those who raise their own animals for meat and want to make use of all parts of the animal.

What You'll Learn

Bone meal is a good source of calcium for chickens
When feeding chickens, bone meal is typically limited to less than 5% of the diet content because of the high calcium, phosphorus, and lysine content of the meal. Calcium is especially important for laying hens. While some feeds are marketed as free of meat and bone meal, this is due to the mad cow scare in Europe, where infected animals were rendered into bone meal, which was then fed to others, resulting in the spread of the disease.
Some chicken owners prefer to feed their hens eggshells as a source of calcium, as it is easier for the chickens to absorb since it came from chickens in the first place. Oyster shells are also fed to laying hens. However, bone meal is a good alternative source of calcium for chickens and can be easily made at home by crushing bones into a fine powder.

It is also a good source of phosphorus
Bone meal is a good source of phosphorus, which is essential for a strong root system and robust plant growth for healthy flower and fruit production. Phosphorus also provides the ability to produce viable seeds to save for the following growing season. In addition to benefiting plants directly, phosphorus is responsible for reducing pest pressure.
All bones contain phosphorus, so any animal bone will do for making bone meal. Bone meal is typically made from beef bones. However, chicken, pork, and beef bones can also be used.
Bone meal is an excellent source of phosphorus for chickens. Chickens are omnivores, and they eat bugs, insects, and beetles to get their protein and minerals. Bone meal is a good source of calcium for chickens. It is also a good source of calcium supplementation.
It is important to note that bone meal should be limited to less than 5% of a poultry diet's content because of its high phosphorus content. Too much phosphorus in the soil can displace other nutrients, inhibiting the plant's ability to photosynthesize and produce chlorophyll.

It is not a good source of protein
While bone meal is a good source of calcium and phosphorus, it is not a good source of protein. Bone meal is a mixture of finely and coarsely ground animal bones and slaughterhouse waste products. It is used as a dietary supplement to provide calcium and phosphorus to monogastric livestock.
Bone meal is often used as a calcium supplement for plants and animals. It is also sometimes used as a fertiliser. However, it does not provide a significant amount of protein.
When it comes to chickens, it is important to note that they are omnivores and require a balanced diet that includes both plant and animal matter. While they can eat bone meal, it should not be relied upon as a source of protein. Instead, chickens typically eat bugs, insects, and beetles to fulfil their protein requirements, in addition to obtaining essential minerals.
Furthermore, there are safety concerns associated with the use of bone meal as animal feed. Improper application in animal nutrition has been linked to the spread of transmissible spongiform encephalopathy, commonly known as Mad Cow Disease. As a result, many commercial feeds are marketed as free of meat and bone meal to address consumer concerns.

It is important to sterilise bones before feeding to chickens
While bone meal is a good source of calcium for chickens, it is important to sterilise bones before feeding them to your chickens. This is because uncooked bones can become a pathogen risk, especially chicken bones. The U.S. Food & Drug Administration (FDA) recommends the following cleaning steps for pet parents who feed raw: ensure you wash your hands with soap and water for at least 20 seconds after handling raw meat or bones. Wash your hands after touching surfaces or objects that may have come into contact with raw meat or bones.
- Soak the bones in warm, soapy water using a mild detergent. Rinse thoroughly with clean water. For degreasing, soak them in warm water with a bit of dish soap for a few days, changing the water daily, and repeat if necessary.
- Soak the bones in equal parts hydrogen peroxide and water for 24 hours to whiten them. Lay the bones outside for several days to dry them completely.
- Use biological washing powder. Add the powder to hot or warm water (not boiling) and leave the bones in for a few days. Rinse the bones well and then dry them.
It is important to wear gloves when handling bones to protect yourself from any viruses or bacteria the bones may contain.

Mad Cow Disease was spread in Europe by infected meat and bone meal
Bone meal is a great source of calcium for plants and animals. It is made from leftover bones and can be added to chicken feed. However, it is important to note that bone meal is not a good source of protein.
Mad Cow Disease, or Bovine Spongiform Encephalopathy (BSE), is an incurable and fatal neurodegenerative disease in cattle. It is believed to be caused by a misfolded protein called a prion. Cattle are thought to have been infected by being fed meat and bone meal that contained the remains of infected animals. This practice of feeding meat and bone meal to cattle was widespread in Europe prior to 1987. The outbreak of Mad Cow Disease in the United Kingdom increased due to the feeding of meat and bone meal to young calves.
In November 1986, bovine spongiform encephalopathy (BSE), commonly known as Mad Cow Disease, was first identified in the UK. It was discovered that the disease was caused by the incorporation of meat and bone meal into ruminant feed. As a result, in 1989, France banned the import of British meat and bone meal. The following year, the European Community ruled that BSE-infected animals did not pose a danger to human health, and imports of British meat resumed. However, this did not prevent the spread of Mad Cow Disease to other countries in Europe, such as France, which reported its first case in 1991.
The Mad Cow Disease epidemic has been attributed to the recycling of animal cadavers, including bone and meat parts not used in human food. The epidemic took a significant turn when it was realized in 1996 that the disease could be transmitted to humans through the consumption of meat products. This led to a collapse in beef consumption in the 1990s as consumers became concerned about the potential transmission of BSE to humans.

Bone meal is a good source of calcium and phosphorus, which are essential for strong bones and healthy plant growth. It is safe for chickens to consume as they are omnivores.
Bone meal is a good source of calcium supplementation, which is essential for strong bones and egg production in chickens. It also provides phosphorus, which is important for a strong root system and robust plant growth.
Bone meal should be limited to less than 5% of the total diet content due to its high calcium, phosphorus, and lysine content. For context, a healthy dog being fed homemade dog food should have 1/2 a teaspoon of bone meal added to each daily serving.
Yes, bone meal is safe for chickens to consume as they are omnivores. However, it is important to note that bone meal made from cooked bones can be dangerous as they become brittle and sharp and can puncture intestines.
Many feeds are marketed as free of meat and bone meal due to the mad cow scare in Europe. Infected animals were rendered into meat and bone meal, which was then fed to other animals, resulting in the spread of the disease.
