What horse feed is best to feed for weight gain ?

With winter and the colder weather it can be hard to maintain horses in peak condition. Regularly weighing and assessing your horse’s body condition score (BCS) (read more about how to assess your horse’s body condition here) will help you to spot the signs of weight loss early.

Before making changes to your feeding programme, it’s important to eliminate other possible causes of weight loss such as a parasitic burden, poor dental condition or equine gastric ulcer syndrome. Alongside a feeding regime, it’s also vital to ensure that your horse is given plenty of forage, ideally ad lib, to help maintain a healthy digestive system. Another benefit of feeding ample forage is that it will help keep your horse warm during colder weather.  This is because heat is produced when fibre is fermented in the hindgut.

What do I need to feed for weight gain?

Like humans, horses gain weight by consuming more calories than they use. Therefore, when selecting a feed for weight gain one of the most important factors to consider is its energy (calorie) content, which is measured as mega joules of digestible energy per kilogram of feed (MJ/ kg DE) – the higher the number, the more calories it contains. Typically, feeds marketed at promoting condition, such as Conditioning 14 Mix or Cool’N’Conditioning Cubes, contain around 12-13.5 MJ/kg DE.

It is also important to consider the recommended feeding rate. A low intake balancer is obviously going to provide less calories, because you feed relatively small amounts, than a feed designed to be fed at a higher rate. The only exception to this are products that have been specifically formulated to be very high in calorie, even when fed in small amountsFor example, Define & Shine is a calorie dense (15.5MJ/kg) pellet that can be added to an existing diet to provide an extra source of calories, whilst keeping meal sizes small.    


Which ingredients are most effective for weight gain?

Almost all the ingredients in a bag of feed will contribute to the overall calorie content including; cereals (e.g. oats, barley, maize), fibre (e.g. sugar beet, soya hulls, wheatfeed) and oil (e.g. linseed oil, soya oil).  Of these ingredients, the most calorific ingredient is oil, which provides approximately 2.5 more calories than cereals. Our Conditioning Mix and Cool’N’Conditioning Cubes are formulated to be high in oil. When extra, non-heating calories are needed Define & Shine can be added to the ration. Define & Shine contains 18% oil and includes beneficial omega-3 fats.

It is important to consider the quality of the ingredients and the processing techniques used to make the feed to ensure it is as digestible as possible for your horse. All of Connolly’s RED MILLS feed are produced using only the best natural ingredients and our five-stage process, known as Precision Nutrition. The unique RED MILLS manufacturing processes of steam cooking, extrusion and double pelleting ensure maximum digestibility and that all nutrients are readily available to the horse during digestion.

My horse is excitable, what feed ingredients should I avoid?

Cereals (for example oats and barley) provide what is commonly referred to as ‘fast release energy’, as they are digested and absorbed into the blood stream relatively quickly. High cereal feeds may exacerbate ‘fizzy’ behaviour in horses that naturally have an excitable temperament, although the reasons for this are not fully understood.  On the other hand, fibre and oil are broken down and absorbed relatively slowly. Consequently, they are known as ‘slow release’ energy sources. Nervous, excitable, or stressy horses can often ‘waste energy’ and as a result may lose weight. To help these horses maintain optimal weight and promote an even temperament a feed that provides energy from fibre ingredient (e.g. sugar beet, soya bean hulls, alfalfa meal) and oil will be more suitable than a cereal-based ration. We have a range of low starch feeds to suit almost every horse. View our low starch horse feeds here.

How quickly will my horse put weight on?

Weight gain will not happen overnight; it takes time and will depend on how much weight the horse needs to gain. The National Requirements for Horses suggested that it takes 16-20 kg of weight gain to change a horse’s body condition score by 1 unit (based on a 500 kg horse; 1-9 scale). Consequently, it will usually take at least 3-4 weeks before horse owners can see noticeable weight gain. It should be noted that severely emaciated horses will require specific dietary and veterinary support as they can suffer from an often fatal condition known as re-feeding syndrome.

My horse’s weight is ok but he is lacking muscle, what can I feed him to help him develop topline?

Topline consists largely of muscle, which is predominately made from protein. Protein is made up of non-essential and essential amino acids. The latter cannot be made in the body and must be provided in the diet. Good quality protein is rich in these essential amino acids and plays an important role in building and maintaining muscle tone, as well as repairing exercise-induced muscle damage.

When selecting a feed to help support topline development it’s important to look at both the crude protein level and the list of ingredients, both of which will be listed on the bag/label. This will help you ascertain the overall protein content of the feed and, more importantly, the quality of this protein.  Good quality protein sources (e.g. Hi-Pro Soya or Full-Fat Soya) should appear high up on the list of ingredients.  For horses needing additional support to maintain condition and develop topline Define & Shine is idealThis high calorie and protein pellet aids weight gain and supports muscle development. It is rich in branch chain amino acids (BCAAs) which, alongside exercise, help your horse’s topline by limiting muscle soreness and preserving muscle mass. Read more about BCAAs here.  For good-doers needing topline a conditioning feed is likely to be too calorific and in these situations a feed balancer such as PerformaCare Balancer is an excellent choice. This will provide a concentrated source of quality protein (30% crude protein) and essential vitamins and minerals, whilst limiting calorie intake.

It’s important to remember that it can take a few months to build topline on a weak horse and feed is only one piece of the puzzle. A suitable exercise regime that targets the correct muscle groups is also essential.
