Disciplines of animal science: animal breeding and genetics, nutrition, physiology, animal health, ethology, meat science, dairy science, biotechnology. Livestock management systems: designing safe and good food without damaging resources, animal science focuses mainly on the livestock industry. Cattle and climate change: livestock accounts for 6% of greenhouse gas emissions annually, actually less because of plant turnover. Grass fed vs. grain fed: grass requires more inputs, produce more methane, and require more land/energy. Cholesterol: beef is not as bad for you that people believe. Hormones: there is little to no absorption of additional hormones. Antibiotics: all antibiotics have to be out of the system before meat can be slaughtered. Muscle grows first along with bone, fat comes later. Hormones: anabolic androgens (steroids in males that promote muscle growth, cortisol and corticosterone can limit growth because of stress.
