Roasted Soybeans and Flavor of Meat

[bigredfeather]

For the first time, I am raising a batch of Cornish Cross on a ration that includes about 30% roasted soybeans (they're organic). The RSB smell and taste really good to me. I was wondering if anyone who has done the same could tell a difference in the taste of the meat when RSB are used in lieu of extruded or SBM. They are just a week old and growing and eating well.

Thanks.

All commercial chicken are raised on about 30% roasted soybeans.All soymeal is roasted( cooked).

NO, that is not correct.

The Roasted Soybeans BRF is asking about are called Full Fat Roasted Soybeans in the feed industry. The whole soybeans are roasted to inactivate the Trypsin Inhibitor present in soybeans. The soybeans you reference in commercial feeds is actually Soybean Meal and was previously called Soybean Oil Meal. It is a co-product of extracting the oil from the soybeans with the use of heat and a solvent, typically hexane. While the Soybean Meal is heated it is a different process and product than Roasted Soybeans.

BRF:

I can not comment on flavor but I will caution you on the fat level of the feed. Since Soybean oil is a vegetable fat it can lead to soft fat in animals.

Could you please explain what soft fat is and why you are cautioning me about it?

This ration has 8.1% fat. At 30% inclusion of RSB, do you think I need to be concerned? Is there something I can do to avoid it?

These chicks are just a week old today, and they seem to be bigger at this age than any batch I have ever raised.

I could be wrong, but my understanding is that chickens naturally have soft fat anyway. The issue is with animals that usually have hard fat, like pigs and cattle. With those if you feed too much of high fat foods, like soy or peanuts, the fat that is usually hard can become soft. I learned about this with soap making. Chicken fat will not produce a bar of soap, although it can be used as a soft, scoopable soap. You need hard fat, like pork back fat or suet, to make hard bars of soap.

You're correct, Elke. My summary was not applicable to chickens.

I found several research reports in peer reviewed journals that showed an improvement in gain, feed conversion, and meat yield with the addition of soybean oil up to 6% added fat.

Interesting. I would not have thought about adding oil to feed. But then again, I am raising my own chickens because I want better taste and to control the quality of my meat, so I am not looking for the fastest growth possible. I wonder how they add the oil. It must be mixed into the feed, but you couldn't do it too far in advance because the oil would go rancid.
