 Many beautiful flowers found in the pastures of Kootenai County can be poisonous. For some, even one small bite may cause abortion or illness. If your fields are full of lovely flowers, you might want to determine if they are toxic prior to turning your livestock out to graze.

Accurately estimate horse weight:

Measure the girth in inches and the length from the point of the shoulder to the point of the butt (also in inches). Multiply the girth by the girth and then by the length. Take that number and divide by 330 which should give the weight in pounds within approximately five pounds of a scale weight.



Housing Arrangements to AVOID:

Chickens and turkeys: because chickens can carry a parasite called Heterakis gallinarum which carries ‘blackhead’, a disease caused by Histomonas melegridis. Though not harmful to the chicken, Histomonas melegridis is fatal to turkeys.

Horses and cattle on mineral blocks: because most cattle licks contain Monensin or Rumensin which is fatal to horses even in very small doses.

Cats and dairy animals: because cats are the definitive host for Toxoplasma gondii and carry it without clinical signs. Cats inadvertently spread it by defecating in grain bins or into other livestock feed sources. Toxoplasmosis can cause muscle damage to livestock, and is passed into milk. To avoid human infection, it is best to pasteurize the milk.

Livestock and marshy areas: because the mud snail may be accidentally ingested and it carries the liver fluke Fasciola hepatica. Rarely fatal, the liver fluke generally causes loss of production in horses and livestock, and at slaughter may lead to a condemned liver and/or carcass.

Dogs and cattle: because dogs can shed Neospora caninum in their stools and contaminate the pasture. Though relatively harmless to the dog, Neospora caninum may cause pregnant cows to abort.



Deworming is Important!

Many parasites can survive freezing and hot summer sunlight. They can be transported by wildlife, birds, and neighborhood animals. Even if you pick up your animal’s waste, and/or drag or treat your pasture, you should deworm at least twice a year. It may greatly improve your animal’s health, hair coat, happiness, and production. If you keep many animals on a small area, you may consider deworming more frequently. For a recommendation specific to your operation and production goals, please don’t hesitate to call.
