Tool 3.1 Lamb growth planner
To plan the average lamb growth rate to point of sale:
- Separate the mob into top, middle and bottom thirds to account for natural variation.
- Complete the table for each mob.
- Calculate the estimated average days to sale weight.
- Calculate the growth rate required (grams per head per day) to achieve the target market.
- Use this information to plan the utilisation of available forage (see chapter 8.3 in MMFS Module 8 Turn Pasture into Product)
