Grass-fed Beef Research Highlights Nutrition and Quality

Grass-fed beef producers in Iowa cooperated with Practical Farmers of Iowa in a study that looked at carcass characteristics, meat quality and fatty acid composition of 100% grass-fed beef. The research found that that ultrasound was not a viable tool for predicting optimal harvest windows for these farmers, when used on live grass-fed cattle prior to harvest. The project also tested grass-fed ribeyes for omega-6:3 ratio and found that both these producers’ products fall within the range of recommendations for healthy diets. Furthermore, the study found that omega ratio and meat quality were not negatively affected by feeding cattle over the winter.
