Document Summary

All 3 types of growth curves are used when measuring whole body animal growth. 3: cumulative curve, absolute growth curve, bell shape curve, doesn"t count the time point when the animal grows, relative growth curve, you get adg, you will see the youngest animals growing faster. Shape of growth curve changes: based on species, breeds, gender, nutrition, etc, changes based on: mature weight, when growth occurs during an animal"s life. At different times of growth, the growth rate is different. Age & maturity: chronological age, at different chronological ages, the growth rate changes. If you feed animals very well, and they grow fast: the cumulative curve will shift to the left, when animals growth slower cumulative curve will shift to the right. Indicates bone growth: for muscle- longissimus muscle area, longissimus dorsi muscle. Indicator of muscling/muscularity: for fat- back fat thickness.
