new research debunks trad views on nutrition

[Geena]

I thought this study was interesting. It's a shame we don't/can't recycle more food waste into livestock feed.

Abstract - There is renewed interest in utilizing food waste as animal feed due to its potential benefits in reducing feed cost and environmental impact while improving global food security. This study was conducted to examine the efficacy of recycled food waste-based feed for laying hen performance, egg quality, and nutrient digestibility.

Feeding recycled food waste improved feed efficiency in laying hens from 24 to 43 weeks of age

What's old is new again. before the large conglomerates that's what small holders did.

Yes, food waste cooked as directed. And not old rotten/ moldy stuff either.

The problem, I suppose, is in the logistics and labor costs of handling it.

And keeping it free of packaging, etc.

We throw out a shocking amount of food at the grocery store where I work, but I can't imagine how it could possible be salvaged because it would require special handling, extra refrigeration, etc.

And farmers would sue if anything was spoiled and made their animals sick.

Yes it's not like the small store and the local farmers that came and got it every couple days.

Interesting study, although the food waste ended up being pretty highly processed by the time it went to the chickens. Still, I suspect that human quality waste food probably is more nutritious then the corn/soy livestock blend. But @3KillerBs is right, that going to be a complicated set of logistics to scale up.

I was surprised that they only put 14% protein into the feeds.

It would unfortunately have to come directly from the producers or manufacturers, due to the possibility of tampering.

The main problem nowadays is that North American governments (I can't speak for the rest of the world) has made it nigh impossible for small farms. Subsidies and such all go to the big conglomerates, who in turn elect the governments.

Yep, you'd have to have a system in place where the food waste was picked up daily and delivered directly to the processing plant and then processed in a timely manner. It could be done but the logistics of it all would be difficult.

As far as spoilage they used-
"Steam heating to exceed 100 °C for 30 min as described in Boyle20 was used during the food waste processing to ensure the inactivation of pathogenic and spoilage organisms. "

It's one of those things that's a good idea in theory, but maybe not so much in practice. I can't help but think of this episode of Dirty Jobs

This would destroy almost all nutrition. That's the reason that most pet foods contain so many additives (as in vitamins and minerals) because the food is killed during processing. Nutrition has to be added back in.

Heat does reduce the levels of some vitamins and nutrients, but nowhere near destroying almost all nutrition, otherwise those of us that cook our food before eating it would have all died from malnutrition by now
