Buffalo vs. Beef: Which Protein is Better? - Thomas DeLauer… What is grass-fed beef v grain-fed beef? The way cows are fed can have a major effect on the nutrient composition of the beef that we consume. Fatty Acid Comparison: Grass-fed vs Grain-fed-
What a cow eats can have a major effect on the nutrient composition of the beef.
This is particularly evident when it comes to the fatty acid composition. Grass-fed beef tends to be much leaner than grain-fed beef, and as a result, lower in total fat. However, grass-fed beef can have 2-6x more “good” fats in the form of omega 3’s.

Major Cons of Grain-fed:
-Higher Incidence of Bacteria Growth. Conventionally” raised cows carry a greater risk of spreading E. coli infection to humans due to the higher incidence of harmful bacteria growth in grain-fed animals, and fecal contamination in feedlots and on kill floors. “Conventionally” raised meats contain residues of everything the animal was exposed to, which includes veterinary drugs, heavy metal residues, and pesticides from their grain-based diet.

Buffalo Meat:
Regulations and industry standards don’t allow the use of hormones or routine antibiotics, which are often given as growth promoters to cattle. According to the USDA, “antibiotics and growth hormones are not given to buffalo, they are allowed to roam freely most of their lives and are raised on the open range and eat hay or grass.” This means that any buffalo meat you eat won't be laced with growth hormones – should all technically be grass-fed buffalo.

All bison are grass-fed, though some may be "finished" on grains. “Finished” refers to the time that animals are fattened for the last few months before slaughter. Bison that have been exclusively grass-fed and grass-finished will typically be labeled as 100 percent grass-fed.
In addition, grass-fed buffalo meat nutrition includes higher levels of two
powerful antioxidants; beta-carotene and selenium than beef. It also has more iron than conventional beef. However, it has a lower amount of saturated fats.

Buffalo v Grass-fed beef:
- Buffalo contains higher levels of beta-carotene and selenium than beef
- Buffalo has less calories and less fat than grass-fed beef – leaner cut of meat
- Buffalo has less saturated fat than grass-fed beef – less omega 3’s
