Besides top-quality pesticide and preservative-free ingredients, Mazuri also fortifies their food with Lactobacillus and Enterococcus sp. probiotics that will help with digestive health and the immune system. Flaxseed oil provides Omega-3 fatty acids that will help with your pet’s eyesight as well as promote a shiny, healthy coat.

    The downside to Mazuri Timothy-Based Rabbit Food is the same as many healthy brands. Some rabbits won’t like it and won’t eat it. We tried several methods of introducing the food, but no matter what we did, there were a few rabbits that wouldn’t even try it.

    The Sherwood SARx Plus brand is a bit of a recovery food meant to nurse sick rabbits and those who are experiencing weight loss back to health, but some people also like to use it as a weight gain food. It’s a complete meal and contains a balanced set of vitamins and minerals. This meal is a powdered formula that you mix with water to the desired consistency. It’s soy and grain-free and contains ingredients meant to stimulate the appetite and increase energy.

    The thing we didn’t like about the Sherwood SARx Plus brand was that about half our rabbits wouldn’t eat it without some sort of extra added to it, like a piece of fruit. Also, our rabbits would make a giant mess of this wet food if we fed them unsupervised. It would get on their fur, and they would track it around on occasion.

    Sherwood Pet Health Adult Rabbit Food changed the smell of our rabbit’s waste for the worse in our opinion despite claims that it improves odors, but that is just our opinion. Also, this food contains alfalfa, which is high in calcium and can lead to bladder stones. If your rabbis weight loss is due to urinary tract problems, this might not be a good food to use for gaining weight.

    Some of the problems we experienced with the Wild Harvest Wh-83544 Wild Harvest Advanced Nutrition Diet For Rabbits brand was that there is a lot of fruit, which can easily upset your rabbit’s digestion.

    Buyer’s Guide

    Let’s discuss the best ingredients and methods you can use to put weight on your rabbit.

    Health

    According to The Rabbit House, rabbits have excellent digestive systems and rarely have weight issues. If you notice your rabbit losing weight, it could be a sign of an underlying health problem, and you should take your pet to see a vet.

    Pellets

    Pellets, or dry food, is the easiest way to increase the weight of your rabbit. These foods have plenty of nutrients and calories, so we usually only feed our rabbits 1/8 to 1/4-cup per day. Increasing the pellet count will almost always increase weight, but you want to do it carefully with healthy food that doesn’t contain harmful ingredients.

    If your rabbit is an adult, you can also use foods that target baby rabbits, and sometimes breeding rabbits, to get the extra nutrition. This additional nutrition per pellet also means your rabbit won’t need to eat more food gain weight, and there may be more care taken in the manufacturing of the food for baby rabbits.

    Alfalfa

    Alfalfa is a type of grass that has a high nutritional content, but it also includes dangerous calcium, which can lead to bladder stones in some rabbits. If your rabbit has lost weight because of complications due to bladder stones, you may want to consult with a veterinarian before using alfalfa for weight gain.

    Fruits

    We usually only recommend fruits as snacks for rabbits because they have sensitive digestive systems that have a hard time with the fermentation process that happens when they eat fruits. It can cause them to develop painful gas and other digestive problems.

    If your rabbit isn’t eating, fruit can be a great way to entice them into taking a few bites. Rabbits usually like fruit, and they may start to eat again in some cases. If your rabbit is already eating, adding some extra fruit treats to their diet can help increase weight, but you will need to watch out for signs of gas and other digestive problems.

    Oats

    Most rabbits enjoy oats, and they can help get even the most stubborn rabbit eating again. Oats are also one of the fastest roads to increased rabbit weight. However, they supply almost no nutritional value to your rabbit, so most people shy away from them and opt to treat with fruit instead. PETA  list oats as one of 15 foods that could harm or kill your rabbit.

    If your rabbit needs to gain weight, you can feed them about one teaspoon per day mixed with water. Oatmeal is also good for blending in medicines or other ingredients your rabbit might require.

    Changes in Diet

    As we have said many times in this short guide, your rabbit’s digestive system es extremely sensitive and easy to throw off balance, it’s essential to make any dietary changes slowly over several days. If you are changing the food or increasing new foods like fruits or oats, give your pet slightly more each day and work up to the correct amount while keeping a close eye on your rabbit for any signs of problems.

    Conclusion

    When trying to add weight to your rabbit, often, the best solution is to increase their normal pellet intake slightly. We normally only give rabbits a small amount, so any increase is bound to add weight. We recommend changing the diet in tiny amounts to give your pet time to adjust and only use the highest quality food. Manna Pro Small World Complete Rabbit Food is our top choice and is a perfect example of high-quality food that will add weight without introducing undesirable ingredients or chemicals. Oxbow Oat Hay Small Animal Food is an example of low-cost hay that can also help increase weight naturally.
