I was experimenting
only on the dead ones. The live ones would
only have been caponized after I knew how to sex chicks and do the surgery with minimal trauma. This was clear in my post I think. Does that get me off the Dr. Mengala hook? Frankly, I think I am owed a couple of apologies.
It seems only Turtlebird suggests a productive use for these culls, but one that still offers only a short life of rapid growth as meat birds, unless these culls are generally smaller and less likely to have heart problems. Do Capons have heart problems even though they grow larger in the longer run? Would caponizing actually improve the life-span of the culled roosters?
Fred, I sit humbly chastized. However, I do not have the same faith as you that every assurance of food safety and quality made by the Gov is accurate and universally enforced. Check out the following article:
http://www.scientificamerican.com/article.cfm?id=soybean-fertility-hormone-isoflavones-genistein.
Quoting from the article in Scientific American: "New studies suggest that eating large amounts of soy's estrogen-mimicking compounds might reduce fertility in women, trigger early puberty and disrupt development of fetuses and children.' The article is from 2009. The response from a spokesperson for the infant formula industry is typical denial. Would you expect any less from the poultry industry or its government defenders when it comes to soy in chicken feed, when the same ilk is perfectly happy to have it fed to our babies?
And what about the hormonal effects of soy on meat birds and the humans who eat them? I suppose I sound like I'm looking for conspiracies. Not exactly. I think Agribusiness just uses the soy because it works. They don't know why and don't care. They also care about as much about the health consequences for humans as they do for the quality of life for their birds. You should see the working conditions of itinerant "chicken-catchers".
Fred, from the US Gov quote you provided:
Part of the poultry industry's increase in productiveness has
largely been attributed to the efficiency of conversion of feed to gain -or- egg production. This increased efficiency can be
largely attributed to imp'rovements in genetics and nutrition." [bold italics mine.]
Please note the qualifiers "Part" and "largely". Combine these two and you are left with a very vague statement. It's an old trick. What is exactly being said here? Is the "part" the Gov mentions something like 90%, or 10%? "Largely", at least, must mean something over 50%. When you combine the two qualifiers the statement loses all its meaning. I expect the other reasons for the increase in productivity are things we might less want to hear about, like antibiotics or the incineration of otherwise healthy living birds who happen not to fit the corporate mold. Not to mention the fairly recent introduction of soy protein to feed.
Turtlebird said, "It sounds as though this is your first exposure to the modifications that humans have made in chicken economics." While I am fairly new to raising chickens on the homestead, I have had sufficient direct and anecdotal experience with factory farms, going back more than 40 years, to know a little of what I am talking about on that score. What the Government and the poultry industry say is going on there is not necessarily the only source of information that should be considered. Those who do the work on the farms don't always have the technical knowledge or facts straight, but they know what they know.
I'll check the threads on Cornish X on the homestead for help, but I still maintain the whole dynamic cannot be reduced simply to a genetic cross. From Wikipedia: "Meat-type chickens currently grow to market weight in six to seven weeks whereas only fifty years ago it took three times as long. This is due to genetic selection and nutritional modifications (and not the use of growth hormones, which are illegal for use in poultry in the US and many other countries).' It seems to me that this conclusion is simplistic, and that the evolution of modern factory broiler production has involved an integrated back-and-forth between feed additives/adjustments and genetics, and that this breed might (I said might!) specifically respond to the hormonal effects of soy protein, progressively increased in animal feed over the same period.
I suppose I'll just keep acquiring culled birds, and yes, experimenting.
