What is the difference between the growth and the low?mum bought 3 bags of the low accidently when he was on the growth so was wondering whether i should change it back or just go with it?
Check the Winergy website which gives details of protein etc. At this time of year I'd say most horses could cope with a reduction in ingredients for the time it takes to use 3 bags.
The low is only 3% starch whereas if i remember rightly the growth is 8% and lower in oil than the growth. they are both cereal free so it is really just a bit less energy! Unless you are working the horse hard I would not worry at all. Mine events off the low energy - its high enough spec in vits and mins that it is fine!
The Growth is a lot higher in calories and quality proteins than the low, so if you are using the Growth for condition, you may find that your horse drops a bit. However, the weather is warmer and the grass should be good, so might not drop off at all. If you are working your horse hard you may also find that it may drop weight as the low may not provide enough calories for the amount of work you are doing. I'd ring the helpline if in doubt - they're very helpful!
