When to weigh LambPlus lambs? Check these tables.
As part of the LambPlus programme breeders are asked to record at least 3 weights for their lambs after lambing at 3 defined points in time as outlined below. Breeders are however free to record as many weights as they wish.
All lambs DO NOT need to be weighed when they are exactly 40, 100, or 150 days of age. If lambs are weighed between the parameters outlined below, the Sheep Ireland database will be able to predict the weight of the animal at age.
These tables are designed to aid breeders in selecting the best time to weigh their LambPlus lambs.
Each of these weights will then work towards improving the flocks accuracy percentage (Acc %) and therefore making the evaluations reflect the performance of the animals on the ground more accurately.
| Weighing | Possible Age Range |
|---|---|
| 40 Day Weight | Between 20 – 65 days of age |
| 100 Day – Weaning weight | Between 66 – 120 days of age |
| 150 Day – M&F Scanning Weight | Between 121 – 180 days of age |
