NO! Crossbow Cattle do not vacinate with mRNA vaccinations and per the National Cattlemen's Association (as of Sept 2023), there are no such vaccinations currently on the market for cattle, (there are, however, in pork). There are talk that mRNA is being tested in cattle currently. Here at Crossbow Cattle, we believe in proper nutrition and care of the herd. If we provide our cattle with the nutrition they need, then the built in immune response would be there when they need it to. Nutrition is key and so is low stress on our cattle. We have no business giving them some lab engineered DNA altering immune response. This is unnantural. The beef you buy from Crossbow are from what we call a 'closed herd' because we grow calves from birth to harvest. They are not exposed to diseases and sicknesses like most cows that congrege in large congested feed lots being assembled from thousands of miles away and brought from all accross the country. Mass production of anything will yield exposure to diseases in livestock and bugs in food, resulting in the need to control that with vaccinations or herbicides. The answer to this are small farms. Support your small farms so we may be able to continue to provide food and meats free of the stuff needed to keep diseases at bay because we are more able to implement practices such a companion planting, closed herds or rotational grazing to aid in the natural prevention of problems.
