Document Summary
Fat deposition: fat stores present in animal that are essential for life internal fat depots, have fat stores that are not needed for life but are the result of tremendous inputs of feed energy. Fat gets deposited when energy inputs exceed energy requirements. With steers, so much fat has accumulated that often trim away 6% of body weight in fat during dressing and. Adipose tissue: changing role of carcass fat. 1800s to early 1900s fat was desirable. But today: lower caloric requirements due to technology and commodity, fat in general was a bad thing in the past but now its unsaturated fats that are the culprits on unhealthiness. Alternative fatty acid sources plant based. Functions: general classification modified ct, energy store fat has 2. 25 times more energy than cho and proteins, thermal insulator prevents heat loss, mechanical shock absorber.
