Implement Body Condition Score when eyeing up ewes.
The red meat sector always seems to be waiting for the next big thing. History has shown us this method does not deliver as promised most of time and there are significant gains to be made within the farm gate before we need to go looking outside it.
As scanningapproaches, there is an opportunity to Body Condition Score (BCS) ewes as they go through the scanning crate rather than use the eye-o-meter.
Historically we have used the eye-o-meter as a great tool to take off the obvious ewes that are either mud fat or super skinny during the winter. However, even though we have had a great autumn, don't assume how they look correlates to a good ewe condition.
Several farmers have been disappointed once they have put a hand on their ewes. Body condition scoring is a skill that is learnt so if you haven't had the opportunity to be shown how to do it properly, I encourage you to hunt out someone who has and learn from them. Best hour of your time you will have invested that week.
At scanning we can use the rule of thumb to draft off ewes that are BCS 3 or better and those BCS less than 2.
Why? Winter feed is a precious resource so needs to be consumed as efficiently as possible. Consider a mob of a thousand ewes with 50 per cent under BCS 3.0 on March 30. Each ewe requires about 30 kgDM above maintenance to lift their condition by one BCS. You'll therefore use 30,000 kgDM over and above their maintenance feed, to lift the entire mob one BCS. If however, we can identify just those ewes in the mob that are less than BCS 3 and focus on feeding them above maintenance, it will halve the feed used to 15,000kgDM.
The aim is to set stock ewes for lambing at BCS of 3 or better. This has many positive benefits particularly with multiple bearing ewes. Some of the key benefits are: ¦ A reduction in ewe deaths over lambing ¦ Increased lamb survivability ¦ Increased lamb weaning weights
When these benefits are summarised financially, the potential additional revenue on average equates to around $34,000. Some farmers say, "I haven't got time to body condition score the ewes — it's just extra work." Body condition scoring can happen when the ewes are already in the yards for scanning so we need to challenge ourselves when saying we haven't got time. Perhaps it's more a case of we've never been taught to do it so until now.
