The 15KG bag provides a 30 day supply for a 500kg horse. TopSpec Comprehensive Feed Balancer is a very palatable ‘Non-Heating’ pelleted feed that is formulated without cereal grains and is low in sugar and starch. It contains many supplements combined with good quality protein to promote muscle development and topline. The supplements include a top-specification broad-spectrum supplement and specialised supplements including a superb hoof supplement, generous levels of anti-oxidants and sophisticated digestive aids. This superb specification allows horses to utilise far more nutrients from the forage and straights in their diet, which usually means that their hard feed intake can be reduced with many resulting benefits. A complete specification is freely available. Comprehensive Feed Balancer is a very flexible, nutrient-rich feed designed to balance the rations of most horses and ponies simply by adjusting the rate at which it is fed and the products it is fed with. When Comprehensive Feed Balancer is fed, there is therefore often no need to add any further supplements, other than salt and/or electrolytes for sweating horses. The addition of a broad-spectrum supplement, blood tonics, yeast supplements, vitamin E and selenium anti-oxidants, a hoof supplement, immune support, a bone supplement and metabolic support, is a totally unnecessary expense, ineffective and potentially harmful.
