In a flock averaging 60 kg live weight, we can expect a Standard Deviation of about 6 kg (10%). This means that we can expect the following distribution of live weight: about 16% of the flock will be under 54kg 34% between 54 and 60kg 34% between...Read more
For every 1 kg heavier average live weight at mating we can expect an additional 2.5 to 3.0% in scanning percentage. Matt Holden has the firm view that ewe live weight needs to be monitored at weaning in order to achieve target mating live weights...Read more
The following are two hypothetical flocks each of 1000 ewes – they indicate that we can expect that a around 20% more lambs tailed for an increase in scanning of about 30%. The calculations below show that a 1% increase in scanning over 1000 ewes...Read more
For every 100 ewes put to a terminal sire, we can expect an extra 3 to 6 (or even more) lambs due to increased survival, and an extra 1 – 1.5 kg of carcase weight at the same age The terminal sire must be from a flock that has been selected for...Read more
