Nutrient content of ground bison meat

I have been searching for fat and calorie content per volume of ground bison meat, and I have found various conflicting sources. BisonCentral.com lists it as 2.42 grams of fat and 143 kcal per 3.5 oz serving. nutritiondata.self.com claims 14 grams of fat and 190 kcal per 3 oz serving. Finally, healthyeating.sfgate.com says 10 grams of fat and 200 calories per 4 oz serving.

So which is right?
