Toasted Soya Bean Meal

[zoeshiloh]

I posted earlier on NL about feeding Soyal bean meal to horses, and wasn't sure about boiling/cooking before feeding. After speaking to the local feed merchant, they said they have toasted soya bean meal, but they are not sure if this needs further cooking before feeding - can anyone help?

Hiya
I have been feeding Soya bean meal for years ...It is great.
You dont need to cook it again ..but you must feed Limestone Flour when feeding it as a straight
If you are unsure contact Gravenhorse Feeds they do a product called Lingold. It is a Soya bean meal mixed with cooked Linseed.
It is more expensive than getting it from a feed merchant as a straight but atleast they can advise on feeding it
Hope this helps

The majority of processed feeds have Soya in it, since the advent of processed feeds - yes I'm old enough to remember the very first of them - we've begun to have metabolic problems with horses.

Horses never suffered from diabetes/insulin resistance, skin allergies and head shaking. I wish that I could remember the website I found the information on. Found it! See copy below

My own horses and those that I've cared for and had control over the feeding have never had problems - I feed only the basic traditional feeds. However the places I've worked where I've not been responsible for the feeding and the horses have been fed processed compounded feeds I've seen problems.

What’s wrong with soya?
Allergens Soya allergies are on the rise as soya consumption goes up. These days, allergies to soya proteins - the symptoms of which include rashes, diarrhoea, vomiting, stomach cramps and breathing difficulties - are almost as common as those to milk.

Phytates These substances can block the uptake of essential minerals - such as calcium, magnesium, iron and especially zinc - in the intestinal tract. All beans contain phytic acid, but soybeans have higher levels than any other. Oriental children who do not consume fish or meat products to counterbalance the effect of their high-phytate, soya- and rice-based diets have been shown to suffer nutritional deficiency illnesses, stunting, rickets and other developmental problems.

Enzyme inhibitors Soya contains potent enzyme inhibitors, which block the action of trypsin and other enzymes needed for protein digestion. Normal cooking does not deactivate these substances, which can also cause serious gastric distress and reduced protein digestion, and can lead to chronic deficiencies in the uptake of essential amino acids such as methionine and leucine, as well as isoleucine and valine. These are all needed to combat stress, avoid depression, synthesise new body protein and maintain a healthy immune system.

Hemagglutinin Soya products also contain another chemical, hemagglutinin, which promotes clumping of red blood cells. These clumped red cells are unable fully to take up oxygen and carry it, via the bloodstream, to the body’s tissues and organs. Hemagglutinin has also been observed to act as a growth depressant. Although the process of fermenting soybeans does deactivate hemagglutinin, cooking and precipitation do not.

Phytoestrogens Soya contains high levels of oestrogen mimics known as isoflavones, which can disrupt hormone function in both men and women. High levels of circulating oestrogens are a risk for certain types of oestrogen-dependent cancers, for instance of the breast, ovaries and testicles. Animal studies have linked high consumption of isoflavones with infertility and reduce immunity.

Antithyroid agents The plant oestrogens in soya can also cause an underactive thyroid and are implicated in thyroid cancer. In infants, consumption of soya formula has been linked to autoimmune thyroid disease.

Aluminium To manufacture soya protein isolate - the high-protein derivative of soya that is used in snacks, infant formulas, protein bars, breakfast cereals, baked goods, ice creams and yoghurts - soybeans are first mixed with an alkaline solution to remove fibre, then precipitated and separated using an acid wash and, finally, neutralised in an alkaline solution. Acid washing in aluminium tanks leaches high levels of aluminium into the final product. As a result, soya-based formula can contain around 1,000 per cent more aluminium than is found in conventional milk-based formulas.

Tnavas,

Thank you so much for this infomative post. As someone who took all her horses off of anything with soya in it last fall, I can't begin to tell you what a difference it made. This was what I tired before I went the expensive route of IR treatments. Within 3 weeks, I had normal horses again. Not just with fat pads gone, no more sore feet, but also with attitude.

People keep wondering why their horses go bonkers on low startch food and blame things such as protien. While at the same time they keep piling on weight and have to live in a dry lot or muzzle.

I feed alfalfa pellets, oats when needed, flax when needed, a vit and min supp, and plain whey protein powder if and when they need a boost in protein. Oh and speedie beet.

They couldn't be happier or look better. I thought when they came off the miracle feed balancers nobody would look healthy anymore. Quite the opposite, they look amazing.

Hi Terri - glad to see someone else has figured it out. My horses are happy and well. Dare I say it?! My vet has only been out for routine vaccinations and to AI my mare for nearly twelve years.

I guess when I check them later someone will have only three legs!

Do you know what my biggest thrill and proof was? My very hard to breed - erratic cycling mare, was bred on one cover on March 2nd of this year and went into foal. You have no idea how frustrating she'd been for 3 years after I switched to the miracle "Ration Balancers". Actually came into season at the beginning of Feb and we just tracked that one to see what she was doing.

My vet kept insisting the mare was perfectly fine and that no tests would turn up anything with regards to breeding soundness. He was right and once her nutrtion was addressed no more problems.

And yes, we don't see our vet as much anymore either!

I have had my suspicions on soya for a while too, and read recently-ish on COTH (USA site) how much trouble it seemed to be causing some people.

I have in fact tracked down a balancer that the mfr. says has no soya in it, based on Linseed instead, Equimins Advance, worth checking that out?

Toasted soya bean meal is about 44% crude protein and 1 - 2% oil; it is the residue after the oil has been extracted from the soya bean. The manufacturers will have cooked it to a. improve protein digestibility & b. to destroy chemicals called trypsin inhibitors which interfere with protein digestion. It is widely used in animal and human food and is an excellent source of high quality protein (essential for restoring lost muscle and maintaining it). It should be a bright golden colour and not need more cooking. If brown and dull, it has probably been overcooked which will reduce the protein quality.
Nothing is ever perfect in this world; most foods have some drawbacks and soya is no exception. You have to balance these against the advantages. Generally speaking, the higher the dietary inclusion level of an ingredient, the greater the risk of problems. I would suggest a maximum of 1/2 kg day for a 500 kg horse, mixed with existing food and including long fibre (chaff/alfalfa/dried grass); start with much less and gradually increase to the desired level. Stop feeding it if you get any adverse reactions.
Last winter one of my customers recently fed approx 1kg/day of full fat soya to several lean dressage horses; they rapidly regained condition, without any apparent ill-effect. I would not however recommend more than 1/2kg!

The moment we get the left overs from some other process you get problems. I definately wouldn't be feeding protein at such a high level. Oats have sufficent protein for the majority of horses.

Balance the feed to work ratio and generally you have a healthy horse. Feedin gtoo much protein only results in stressed kidneys and your money being peed out by the pound! Excess protein is excreted in the urine.
