Birth Control For Bison - “Romance without Responsibilities”
Why not for Wild Pigs?
Feral pigs are the subjects of discrimination in California. Female feral bison on Catalina Island, California, are being put on birth control. The bulls are left alone to do what Bison bulls love to do: Fall in love. Now they can do so without the serious consequences of romance.
Female pigs do not enjoy such privileges. Why only bison and not female wild pigs? I have suggested birth control for Miss Piggy in a previous article on this blog. Boar would enjoy love without responsibilities as much as bison bulls. So, why are we discriminating?
The answer to this question is found in an article by Louis Sahagun in the Los Angeles Times. Sahagun answers the question indirectly in his article “Catalina bison going on birth control”. It appeared on November 20, 2009 in the Los Angeles Times.
The Catalina Island Conservancy, which owns 88% of the island, is rounding up the bison herd, separating females from the rest and vaccinating them with a contraceptive. The process needs to be repeated after one year. About 200 bison now live on Catalina Island. The contraceptive is effective in approximately 90 percent of bison cows.
An estimated 800,000 wild pigs live in California. They are faster, more agile, more intelligent than bison and not marooned on an island. They have plenty of space for running away. That makes herding wild pigs into corrals far more difficult, if not impossible. Vaccinating boar directly will most likely not work. But administering the vaccine in food should. Lace acorn with it and watch the wild pigs happily vaccinate themselves.
The contraceptive for bison may not work in wild pigs. But if we can develop one, we should also be able to create a vaccine specifically for wild pigs. Bison contraceptive vaccine is non-hormonal. The wildlife contraceptive porcine zona pellucida (PZP ) is developed from pig eggs. The vaccine stimulates the body of an injected animal to produce antibodies that distort the shape of the sperm receptors on the egg. Sperm no longer detect the receptors and thus do not attach themselves to the egg. Fertilization does not take place.
PZP was tested and studied on horses, feral burros, deer and possibly other large mammals as a multi-year vaccination and in animal feed. Why it has not been widely used to control the explosion of wild pig populations is unknown to me.
Be that as it may, for once I agree with the Nature Conservancy, wildlife conservationists and animal rights activists. It is far more humane to control burgeoning populations of big mammals with contraceptives than to engage in the wholesale, cruel slaughter of the animals with poison and from the air.
Tell that to the wild pigs of Catalina Island. They were not given the benefit of contraceptives, not even for test purposes.
They were trapped and killed, poisoned and mercilessly hunted from the air by the brave shooters in the sky, which I despise so much. The lucky ones were shipped out to ranches on the mainland – to be hunted there. Feral pigs are not a tourist attraction like the Catalina bison. Boar are not driving money into the coffers of tour operators like bison. Feral pigs just dig holes, mud holes. There is no money in ordinary mud! And they destroy cash crops and manicured front yards in suburbia.
Wild pigs are not cute and pink. They are ugly, dirty, mean and smelly. They deserve to be murdered from the sky!
The revenge of the boar? They keep on making more and more and more wild boar.
Giving the porkers food spiced with PZP could put a damper on their out of control population increases without depriving hunters of one of their favorite big game animals. But it would not take the fun out of the life of Miss Piggy.
The article in the Los Angeles Times quotes Carlos De La Rosa, chief conservation and education officer of the Catalina Conservancy:
"Bison will continue to be bison. . . . "Males will continue to compete for females, and females will continue to go into heat. The only difference is that we can control how many calves they have.
"For bison in love," he added with a laugh, "this means romance without responsibilities."
What's good for the bison, is good for the boar. Don't you think so?
