Abstract
Disclosed is an improved poultry feed diet composition and uses incorporating the feed composition. The feed composition includes byproduct or waste material from citrus juice extraction. The citrus byproduct or waste is at a concentration characteristic of a feed supplement. These feed supplements improve poultry characteristics and enhance feed conversion when compared with traditional poultry feed diets or supplements which rely on components that are not in their respective native states as present in citrus byproduct from juice extraction equipment.

this also came up a lot of interesting thoughts on what it cost to get into chickens

I got this but it doesn't tell why
maybe something about the acid in the gut

hopefully this puts to rest the falacy about citrus and chickens
maybe the fact that it is processed agrees with chickens diet

I know cooking or processing pineapple kills the enzymes.

Wonder if it's enzymes in citrus that bother chickens? Coz I know the enzymes in pineapple core are tough enough they can make your mouth bleed! But in small amounts they help digestion (for us humans that is) so....
Probably moderation is the key.

People have said that it's bad, but I never believed that. It's true that they often do not like the citrus taste, but there's no reason it should be bad for them.

I have read the citrus isn't bad for the chickens but makes the eggs shell weak from the acids. But I can't remember where I read it. It may have been here in BYC forums.

Altho the info is interesting, I dont find it particularly relevant
> Those studies with the PROCESSED product ... this is quite different than the fresh leftovers (I have never seen the processed product available but in bulk tonnage to the industry)

All of the ingredients tested (study on toxicity levels of the known problematic substance > most notably LIMONENE) in the following study are issues with the fresh product...

excerpt:
"...Conclusions
Nutrition quality of feeds is critical in livestock development. The phytochemical examination of citrus fruits peel meals of Citrus sinensis (Washington variety), Citrus sinensis (Ibadan variety), Citrus limonum and Citrus qurantifolia has shown that they contain tannin, and saponin, phytate, oxalate, flavonoid and limonene in varying highly significant amounts (p<0.01). It was observed that their concentrations in CFPM were lower than the levels at which these chemical compounds have been reported be harmful to farm animals.

The effect the presence of limonene which has been reported to be toxic to pig and especially poultry should be investigated to determine at what level it becomes toxic to various livestock species."

I always have extra grapefruit and ornamental oranges from a couple of trees. I'm thinking I should try them once to see what happens.

Thats logical..

cant remember where I read it but pretty sure citrus is bad for calcium..

Just think oranges and teeth

For us humans parts of the citrus inhibits the uptake of calcium from the digestive tract ie... oj and milk for breakfast is ironic after you learn this little fact in college human nutrition course. It may have some affect on the calium uptake for chickens thereby affecting the eggshells. I agree with moderation being the key here.

At a free course on 'backyard chickens' offered by our extension office, a nutritionalist told the class that chickens, like very few other animals, actually make their own vitamin C. Feeding them citrus is only bad for them due to the excess vitamin C you'd be giving them and could cause them to have too much in their bodies.

There's a major difference between what is found in the citrus peel and what is found in the juice.

Processed citrus pulp, the leftovers after being squeezed for juice, has been a common cattle feed here in Florida for many decades now. I'm inclined to doubt that it would be of much value to poultry though. A lot of the d-limonene is extracted before the pulp is dried as it's a valuable byproduct in itself.

There is not as much ascorbic acid (vitamin C) in citrus juice as some believe. It's an easy nutrient to lose during processing. I'm not sure what value in a poultry feed it may have, but I suspect it's not for its vitamin C content.
