By reading this article you will realize that the dairy cows are no longer vegetarian animals. The dairy industry feeds them recycled meat mixed with regular grain feed. The recycled meat is derived by recycling slaughterhouses waste, dead animals such as millions of euthanized cats and dogs from veterinarians and animal shelters, and supermarket and restaurant waste.
Rendering Plants:
Rendering plants perform one of the most valuable functions on Earth. They recycle dead animals, slaughterhouses waste, and supermarket rejects into various products known as recycled meat, bone meal, and animal fat. These products are used as a source of protein and other nutrients in the diets of dairy animals, poultry, swine, pet foods, cattle feed, and sheep feed. Animal fat is also used in animal feeds as an energy source.

One estimate states that some 40 billion pounds a year of slaughterhouse wastes like blood, bone, and viscera, as well as the remains of millions of euthanized cats and dogs passed along by veterinarians and animal shelters, are rendered annually into livestock feed. This way they turn dairy cows, other cattle and hogs, which are natural herbivores (vegetarians), into unwitting carnivores (non-vegetarians).

However without rendering plants, our cities would run the risk of becoming filled with diseased and rotting carcasses. Fatal viruses and bacteria would spread uncontrolled through the population.

"If you burned all the carcasses, you'd get a terrible air pollution problem," or "If you put it all into landfills, you'd have a colossal public health problem, not to mention stench. Dead animals are an ideal medium for bacterial growth," said Dr. William Heuston, associate dean of the Virginia-Maryland College of Veterinary Medicine at College Park, MD USA.

This is a multibillion-dollar industry, and these facilities operate 24 hours a day just about everywhere in America, Europe and other parts of the world. They have been in operation for years. Yet so few of us have ever heard of them.
Raw Material:
The dead animals and slaughterhouses waste which rendering plants recycle includes:
· Slaughterhouses waste such as heads and hooves from cattle, sheep, pigs and horses, blood, stomachs, intestines, spinal cords, tails, feathers, an bones.
· Thousands of euthanized cats and dogs from veterinarians and animal shelters
· Dead animals such as skunks, rats, and raccoons
· Carcasses of pets, livestock, poultry waste
· Supermarket rejects

Renderers in the United States pick up 100 million pounds of waste material every day. Half of every butchered cow and a third of every pig is not consumed by humans. An estimated six to seven million dogs and cats are killed in animal shelters each year, said Jeff Frace, a spokesman for the American Society for the Prevention of Cruelty to Animals in New York City.

Along with the above material, the Rendering plants are unavoidably process toxic wastes as indicated below.
Toxic Waste:
The following menu of unwanted ingredients often accompanies with dead animals and other raw material:
· Pesticides via poisoned livestock
· Euthanasia drugs that was given to pets
· Some dead animals have flea collars containing organophosphate insecticides
· Fish oil laced with bootleg DDT
· Insecticide Dursban in the form of cattle insecticide patches.
· Other chemicals leak from antibiotics in livestock,
· Heavy metals from pet ID tag, surgical pins and needles.
· Plastic from:
1. Styrofoam trays from packed unsold supermarket meats, chicken and fish
2. Cattle ID tag
3. Plastic insecticide patches
4. Green plastic bags containing dead pets from veterinarians
Skyrocketing labor costs are one of the economic factors forcing the corporate flesh-peddlers to cheat. It is far too costly for plant personnel to cut off flea collars or unwrap spoiled T-bone steaks. Every week, millions of packages of plastic-wrapped meat go through the rendering process and become one of the unwanted ingredients in animal feed.
Recycled Process:
The rendering plant floor is piled high with 'raw product' all waiting to be processed. In the 90-degree heat, the piles of dead animals seem to have a life of their own as millions of maggots swarm over the carcasses.

First the raw material is cut into small pieces and then transported to another auger for fine shredding. It is then cooked at 280 degrees for one hour. This process melts the meat away from bones in the hot 'soup.' This continuous batch cooking process goes on non-stop for 24 hours a day, seven days a week.

During this cooking process, the soup produces fat of yellow grease or tallow (animal fat) that rises to the top and is skimmed off. The cooked meat and bone are sent to a hammermill press, which squeezes out the remaining moisture and pulverizes the product into a gritty powder. Shaker screens remove excess hair and large bone chips. Now the following three products are produced:
· Recycled meat
· Yellow grease (animal fat)
· Bone meal
Since these foods are exclusively use to feed animals, most state agency spot check and test for truth in labeling such as; does the percentage of protein, phosphorous and calcium match the rendering plant's claims; do the percentages meet state requirements? However, testing for pesticides and other toxins in animal feeds is incomplete or not done.
Recycled Products and Usage:
Every day, hundreds of rendering plants across the United States truck millions of tons of this 'food enhancer' to dairy industry, poultry ranches, cattle feed-lots, hog farms, fish-feed plants, and pet-food manufacturers. This food enhancer is mixed with other ingredients to feed the billions of animals.

Rendering plants have different specialties. Some product-label names are: meat meal, meat by-products, poultry meal, poultry by-products, fishmeal, fish oil, yellow grease, tallow, beef fat, and chicken fat.

A 1991 USDA report states that rendering plants produced approximately 7.9 billion pounds of meat, bone meal, blood meal, and feather meal in 1983. Of that amount:
· 34 percent was used in pet food
· 34 percent in poultry feed
· 20 percent in pig food
· Rest (12 percent) in dairy and beef cattle feed

Scientific American cites a dramatic rise in the use of animal protein in commercial dairy feed since 1987.

At least 250 rendering plants operate in the United States and modern rendering plants are large and centralized, and the industry's revenues amount to $2.4 billion a year, said Bruce Blanton, executive director of the National Renderers Association in Alexandria, Va.

Scientists believe the so-called mad cow disease results when cattle eat feed made from the brains or spinal cords of sheep suffering from scrapie. They believe the people who died were infected when they ate beef, or dairy or other products from these cows, a theory that remains controversial, though evidence is accumulating.

The Story of North Carolina - USA
In an article entitled "Greene County Animal Mortality Collection Ramp", states that:
"With North Carolina ranking in the top seven states in the U.S. in the production of turkeys, hogs, broilers and layers, it has been recently estimated that over 85,000 tons of farm poultry and swine mortality must be disposed of annually".

To meet this disposal need, in 1989 the Green County Livestock Producers Association began using an animal carcass collection site. Livestock producers bring the dead animal and bird carcasses to the ramp and drop them into a water-tight truck with separate compartments for poultry and other livestock parked behind the retaining wall.

A local farmer, contracted by the Livestock Association, hauls the animal and bird mortality to the rendering plant each day and maintains the collection site. The rendering plant pays the Livestock Association each week based on the current prices of meat, bone, feather meal, and fat.

During the first 16 weeks of operation in 1989, over 1 million pounds or a weekly average of 65,000 pounds of dead animals and birds (mortality) were collected and sent to the rendering plant.

The end result of this very successful project is that Greene County livestock and poultry producers have a convenient, safe, and economical alternative to dispose of animal and bird mortality.

Also in one of the articles I read that said the waste by products of meat rendering are not as
prevalent as was backseveral decades as meat is not as readily grown to day as was in old days.

Also when read Wikipedia article on rendering animal by products
this some of what is in the article, you can look up the rest

IE:
Rendering is a process that converts waste animal tissue into stable, value-added materials. Rendering can refer to any processing of animal products into more useful materials, or, more narrowly, to the rendering of whole animal fatty tissue into purified fats like lard or tallow. Rendering can be carried out on an industrial, farm, or kitchen scale.
The majority of tissue processed comes from slaughterhouses, but also includes restaurant grease and butcher shop trimmings and expired meat from grocery stores. This material can include the fatty tissue, bones, and offal, as well as entire carcasses of animals condemned at slaughterhouses, and those that have died on farms, in transit, etc. The most common animal sources are beef, pork, sheep, and poultry.
The rendering process simultaneously dries the material and separates the fat from the bone and protein. A rendering process yields a fat commodity (yellow grease, choice white grease, bleachable fancy tallow, etc.) and a protein meal (meat and bone meal, poultry byproduct meal, etc.).
Rendering plants often also handle other materials, such as slaughterhouse blood, feathers and hair, but do so using processes distinct from true rendering.
The occupation of renderer has appeared in "dirtiest jobs" listicles.[1]

IE:
Rendering processes for edible products[

Edible rendering processes are basically meat processing operations and produce lard or edible tallow for use in food products. Edible rendering is generally carried out in a continuous process at low temperature (less than the boiling point of water). The process usually consists of finely chopping the edible fat materials (generally fat trimmings from meat cuts), heating them with or without added steam, and then carrying out two or more stages of centrifugal separation. The first stage separates the liquid water and fat mixture from the solids. The second stage further separates the fat from the water. The solids may be used in food products, pet foods, etc., depending on the original materials. The separated fat may be used in food products, or if in surplus, it may be diverted to soap making operations. Most edible rendering is done by meat packing or processing companies.
One edible product is greaves, which is the unmeltable residue left after animal fat has been rendered.
An alternative process cooks slaughterhouse offal to produce a thick, lumpy "stew" which is then sold to the pet food industry to be used principally as tinned cat and dog foods. Such plants are notable for the offensive odour that they can produce and are often located well away from human habitation.

I feel it is okay for you all to feed the meat scraps and other canned meat to the chickens as you are the ones eating the eggs.
Also the chickens can and do eat people food and meat scraps.
People go so far as to let chickens eat refuge from slaughtered meat products and animals caught in a trap or shot in wild
that surely shows to each his own in feeding chickens and harvesting chicken eggs
for your own use.
I believe it is the multitude of EGG BUYERS that are wanting healthy eggs,
and the fact that the brown egg layers do not assimilate the fish by products in their eggs
to do away with the fish taste in eggs.
This is the primary problem in todays egg production values.

Here is an article worth reading please read whole article this is just a part of it
IE: Poultry Hub
Feed Ingredients
http://www.poultryhub.org/nutrition/feed-ingredients/

Animal protein sources
The main animal protein sources used in poultry diets are meat meal, meat and bone meal, fish meal, poultry by-product meal, blood meal and feather meal. Although the production of animal protein for human consumption has been under continual pressure and marred by much controversy, the world-wide and domestic consumption of animal protein continues to grow and much of the future supply of meat protein will come from poultry. With increased animal protein production there will be increased demand for feed and, in particular, a demand for ingredients high in protein and energy.
The animal industry evolved as a means of adding value (i.e. higher nutrient level and availability, flavour, variety, etc.) to ingredients that were of marginal food value for humans. These ingredients include grains that are of poor quality or damaged by harvest or storage conditions; as well as a means of recycling by-products of brewing, vegetable oil, meat, milk and egg production. Approximately 50% of the live market weight of ruminants and 30% of poultry is by-product. These by-products are rendered, ground and available as a feed source.
