5 months old just weaned. I took advice from a friend on feeding chaff,pasture mix,speedy beat. After looking into it with more detail I see the speedy beat is a no no. What about the chaff and pasture mix??
Yeah, beet pulp, so long as it hasn't got extra sugar(molasses) in it is fine. According to my nutritionist, it doesn't actually need to be soaked. I too would be more concerned with what is in the 'pasture mix' as these sort of feeds generally contain grain & molasses, which are 'no-nos' IMO.
Very basically, horses are best off on grass hay/long stemmed grass, with the addition of good nutritional supplementation. Youngsters also need more protein, of which lucerne/alfalfa is a good source. Especially with such a youngster that you want to ensure to set up well for life, I would suggest you consult an equine nutritionist for specific details. I personally subscribe to a fantastic service called FeedXL.com which has a custom diet analysis program as well as nutritionists at your beck and call.
