Eggshell Powder

Especially calcium plays a large role in  raw feeding.
This can only be achieved through feeding raw bones,or can it?.

Eggshell as suggested is the hard, outer layer of an egg.
It consists mostly of calcium carbonate, a common form of calcium, the rest is made up of protein and other minerals.
Calcium carbonate is the most common form of calcium in nature.
It is also the cheapest and most widely available form of calcium in supplements.
In the past decades, eggshell powder processed from eggs has been used as a natural calcium supplement.
Eggshells are roughly 40% calcium, with each gram providing 381–401 mg of Calcium
Some research suggests that the calcium in eggshell powder may be better absorbed than pure calcium carbonate, making it an effective calcium supplement.

Eggshell powder can improve bone strength in pets with osteoporosis, and easily made at home.
One study indicates that it may be more effective than purified calcium carbonate supplements.

When do I use a Calcium supplement
A pet that has health problems like:
Brittle bones
Calcium deficiency
CKF/CKD (Can not have bone included in their diet)
Dental problems (can’t chew/ crush a bone properly)
Problems with digesting bone.

Not every pet is able or wants to eat bones, it’s not always trouble free Eggshells are high in calcium and eggshell powder is an easy digestible animal calcium source so it would be a good alternative to feeding bone.

When a pet can’t crush/ chew a bone due to dental problems, or has difficulty digesting bone, a calcium supplement is needed to provide your pet with the much needed calcium and eggshell powder can easily help you with that due to it’s ability to be absorbed easily.

When a dog or cat presents itself with bladder/ kidney problems it is advised not to feed bone due to the high phosphorous levels they contain.
This is when a lot of pet owners start to panic as the main source of calcium in a raw diet are bones.
No fear as Egg shell powder can be the answer.

Not only could eggshell powder be a good alternative to eating bone, it could also be a good add on to a raw diet.
General rule of thumb is that calcium vs phosphorous ratio should be a 1-1.
Feeding bone means that you can easily exceed the 1-1 ratio of phosphorous to calcium ratio, as the meat we feed also contains phosphorous and unless you analyse every protein separately (which most of us don’t) exceeding the ratio is easily done.
For this reason some raw feeders prefer to add eggshell powder as well, or alternate feeding bone a few days and egg shell powder another few days (2-3 times a week)

Cat or Small dogs: 2g daily
Medium size dogs: 4g daily
Large dogs: 6g daily
1/2 tsp per 1 lb of meat for a 100% pmr raw diet

Making your own eggshell powder
When making eggshell powder at home, there is no need to remove the membrane.
The egg membrane is located between the eggshell and the egg white. It is easily visible when you peel a boiled egg.
While technically not part of the eggshell, eggshell membrane is usually attached to it.
Eggshell membrane mainly consists of protein in the form of collagen.
It also contains small amounts of chondroitin sulphate, glucosamine and other nutrients.
The trace amounts of these beneficial compounds in eggshell membrane are unlikely to have significant effects on health.
However, some studies show that regular intake of eggshell membrane supplements may benefit joints.
More studies are needed to confirm their potential effectiveness

Shells – There is some controversy going around whether or not we should feed eggs whole (with shell) or without.
Reasoning for this is because it is said that all eggs are treated with chemicals (washed/sprayed) and therefore not safe to feed to our pets but preferred to buy local organically farmed eggs instead of supermarket eggs as fresh eggs straight from the farm have not been through any processes.
Although this is true for eggs that hit the supermarket shelves in the USA the opposite is true for eggs sold in the UK and (some) other EU countries.
