What is it in In Heat Urines
That Make Them Work?
Scent molecules literally jump out of the bottle once the bottle has been opened.
These molecules latch themselves onto anything such as small particles of dust, moisture, and even pollen.
As wind currents move these microscopic particles around the scent travels with them.
Other factors affect dispersion as well. Cold air is dense, heavy air that results in less efficient scent dispersal.
In this situation more lure or scent is needed to reach out to the desired area.
Conversely, warm air is less dense and scent molecules easily escape up and away.
Since molecules need to attach to particles in the air to escape, humidity plays a role as well.
Moist, humid air contains more airborne particles than dry air.
Thus scent molecules grab a ride on the microscopic particles of humid air.
Until someone figures out how to wire up a hogs nose to a human, or to put a humans mind into a hogs brain, we will never be certain what a hog smells when it smells something.
There is no cast-in-stone plan for setting up a scent system. What works depends on the hunting area, conditions, and what the hunter wants to achieve.
In heat urines whether they be hog, deer, or any other type are sometimes a lively subject with various "experts".
Once in a while one of these experts tells us that pheromones have a short life and they will not remain intact while in a bottle.
The real fact is, that nobody really totally understands how everything in the in heat urines has its effect on the male animal, but it does.
Even though in heat urines sound like they may be a fairly simple thing., they are actually extremely complex.
To the best of our knowledge, no one has been able to fully analyze a plain urine and certainly not an in heat urine.
We dont fully understand exactly what it is in it that makes it work, but good high quality in heat urine is highly attractive to the hog or other male animal.
The only way to really find out if a scent is good is to go out in the wild and do field-testing on wild animals. You can also do your field-testing on penned animals but I fully believe that an animal in a pen is not his normal self.
Even if the test comes out in my favor, I still cant put as much faith in the result as I can the wild animal field-testing.
It is important that anyone attempting to develop hunting skills or hunting scents should keep an open mind.
If you dont keep an open mind you will start limiting yourself in the things you want to try and may very well miss out on something that is very effective.
When someone starts making general blanket statements that tell you what type of scents are and arent effective, they probably havent done extensive experimentation out in the field, because if they had, they would know that there are an awful lot of scents that attract the animal hunted, but the degree to which they are effective does vary quite a bit.
Urine is urine, no two ways about it.
The truth is that some urine is better than other urine from the same kind of animal. Diet, collection methods, age of the animal, etc are just a few of the factors that affect urine quality and how it works as a hunting scent.
Common tap water has been found to have up to 3,000 different natural chemicals in it, so you can imagine how complex an in heat urine would be to analyze.
For all practical purposes it simply cant be done.
What is it in the in heat urines that make them work?
Well its the urine, the pheromones, and the other smells that make up the urine.
The fact is nobody has really been able to solve the exact combination of parts of in heat urines that create the strong sexual attraction.
That is why the top quality natural in heat urine works the best and synthetics just cant duplicate it.
Animal urines are extremely complex organic chemical compounds.
The natural urines are so complex, that it would probably be impossible to do a total chemical analysis.
There are just too many minor parts that make them up.
The nose of an expert, can tell one kind of animal urine from another, yet it would require extremely expensive analysis to start looking closely at urines and getting into the simple task of differentiating one kind of animal urine from another through chemical analysis.
It is my opinion, and everybody has one, that advertisements to the contrary are usually marketing ploys by companies more concerned with profit margins than hunter success.
The first pheromone ever identified (in 1956) was a powerful sex attractant for silkworm moths.
A team of German researchers worked 20 years to isolate it.
After removing certain glands at the tip of the abdomen of 500,000 female moths, they extracted a curious compound.
The minutest amount of it made male moths beat their wings madly in a "flutter dance."
This clear sign that the males had sensed the attractant enabled the scientists to purify the pheromone.
Step by step, they removed extraneous matter and sharply reduced the amount of attractant needed to provoke the flutter dance.
When at last they obtained a chemically pure pheromone, they named it "bombykol" for the silkworm moth, "Bombyx mori" from which it was extracted.
It signaled, "come to me!" from great distances.
"It has been soberly calculated that if a single female moth were to release all the bombykol in her sac in a single spray, all at once, she could theoretically attract a trillion males in the instant," wrote Lewis Thomas in The Lives of a Cell.
In dealing with mammals, however, scientists faced an entirely different problem.
Compared to insects, whose behavior is stereotyped and highly predictable, mammals are independent, ornery, complex creatures.
Their behavior varies greatly, and its meaning is not always clear.
What scientists need is "a behavioral assay that is really specific, that leaves no doubt," explains Alan Singer of the Monell Chemical Senses Center.
A few years ago, Singer and Foteos Macrides of the Worcester Foundation for Experimental Biology in Massachusetts did find an assay that worked with hamsters, but the experiment would be hard to repeat with larger mammals.
It went as follows:
First the researchers anesthetized a male golden hamster and placed it in a cage.
Then they let a normal male hamster into the same cage.
The normal hamster either ignored the anesthetized stranger or bit its ears and dragged it around the cage.
Next the researchers repeated the procedure with an anesthetized male hamster on which they had rubbed some vaginal secretions from a female hamster.
This time the normal male hamster's reaction was quite different:
instead of rejecting the anesthetized male, the hamster tried to mate with it.
Eventually Singer isolated the protein that triggered this clear-cut response.
"Aphrodisin," as the researchers called it, appears to be a carrier protein for a smaller molecule that is tightly bound to it and may be the real pheromone.
The substance seems to work through the VNO, since male hamsters do not respond to it when their VNOs have been removed.
Many other substances have powerful effects on lower mammals, but the pheromones involved have not been precisely identified and it is not clear whether they activate the VNO or the main olfactory system, or both.
Humans are "the hardest of all" mammals to work with, Singer says.
Yet some studies suggest that humans may also respond to some chemical signals from other people.
In 1971, Martha McClintock, a researcher who is now at the University of Chicago (she was then at Harvard University), noted that college women who lived in the same dormitory and spent a lot of time together gradually developed closer menstrual cycles.
Though the women's cycles were randomly scattered when they arrived, after a while their timing became more synchronized.
McClintock is now doing a new study of women's menstrual cycles, based on her findings from an experiment with rats.
When she exposed a group of female rats, let's call them the "A" rats, to airborne "chemosignals" taken from various phases of other rats' estrous cycles, she discovered that one set of signals significantly shortened the A rats' cycles, while another set lengthened them.
Now she wants to know whether the same is true for humans, whether there are two opposing pheromones that can either delay or advance women's cycles.
In this study, she is focusing on the exact time of ovulation rather than on synchrony.
The most direct scientific route to understanding pheromones and the VNO may, once again, be through genetics.
Working with sensory neurons from the VNOs of rats, Catherine Dulac and Richard Axel found a new family of genes that "are likely to encode mammalian pheromone receptors," they reported in 1995.
Axel and Buck's teams also found a similar family in the VNO's of mice.
Both groups estimate there must be 50 to 100 distinct genes of this kind in VNO neurons.
Since then, Buck's team and that of Catherine Dulac, who is now an HHMI investigator at Harvard, have found a second family of likely pheromone receptors in mammalian VNOs; these, too, are expected to include about 100 genes.
"Now we have to match up pheromones and receptors," Buck declares.
Once the genes for such receptors are definitively identified, it should be relatively easy to find out whether equivalent genes exist in humans.
Scientists could then determine, once and for all, whether such genes are expressed in the human nose.
If they are, the receptors may provide a new scientific clue to the compelling mystery of attraction between men and women, some evidence of real, measurable sexual chemistry.
So I guess to answer the question "What is it in In Heat Urines That Make Them Work?" I would have to say I dont know, or do I know anyone that does.
But if you use the urines and they bring you success in the field, I guess it really doesnt matter anyway.
The bottom line is Hunter Success, and that is what we strive to help with at "IN HEAT SCENTS".
The one piece of advice I think will help a hunter most is this, "Dont be chained to what you know, EXPERIMENT".
