Proper nutrition supports Champagne d'Argent health, longevity, and wellbeing throughout their lives. Unlimited grass hay available 24 hours daily, 7 days weekly without restriction is the single most essential, non-negotiable component of proper rabbit diet. Timothy hay stands as the gold standard for adult Champagne d'Argent over one year old, providing optimal fiber content (minimum 25-30%) for gut motility preventing life-threatening GI stasis, natural abrasive tooth wear preventing dental disease, and low-calorie bulk allowing constant eating without obesity. Alternative excellent varieties include orchard grass (slightly sweeter flavor often preferred by picky eaters), meadow hay (varied grass mix providing diversity), brome hay, and oat hay (slightly higher calorie useful for underweight rabbits). Never feed alfalfa hay to adult Champagne d'Argent—the high calcium (1.2-1.5%) and protein (15-22%) content are unnecessary and inappropriate for adults over one year, causing obesity, urinary sludge, bladder stones, and kidney problems.
Hay importance cannot be overstated: provides essential fiber preventing GI stasis (the leading cause of rabbit death), wears continuously-growing teeth naturally preventing painful dental disease, and supplies low-calorie bulk allowing constant eating satisfying natural grazing behavior. A Champagne d'Argent should consume hay piles equal to or larger than their body size daily—for a 10-11 pound rabbit, this means roughly 10-11 pounds of hay consumed daily, though actual volume varies considerably with hay density, leaf-to-stem ratio, and individual appetite. Large rabbits consume substantially more hay overall than small rabbits, requiring regular hay purchasing and proper storage.
Freshness matters significantly—rabbits strongly prefer fresh, green, sweet-smelling hay and will eat substantially more quality hay. Purchase from reputable hay suppliers. Good quality hay appears greenish (not brown indicating age or poor storage), smells fresh and sweet (not musty indicating mold), feels soft and pliable (not brittle indicating over-drying), contains minimal dust (shake hay before offering and avoid dusty batches), and maintains good leaf-to-stem ratio (leaves provide most nutrition and palatability). Store hay properly in cool, dry, well-ventilated areas—never in sealed plastic bins that trap moisture promoting dangerous mold growth. Large rabbits go through hay quickly—buying in bulk directly from hay farmers or agricultural suppliers may be more economical and provide fresher product than small pet store packages.
Pellets serve as concentrated nutrient supplements, never as dietary staples or hay replacements. For adult Champagne d'Argent aged 1-5 years in maintenance (not growing, pregnant, or lactating): feed 1/4 cup per 5 pounds of body weight daily. For a typical 10-11 pound Champagne d'Argent, this equals approximately 2 to 2.25 cups daily measured carefully with actual measuring cups, not estimated eyeballing. Large rabbits require more pellets overall than small rabbits in absolute amounts, but portion control remains critically important preventing obesity. Select high-quality pellets containing at least 18% crude fiber (higher is better—look for 20-22%), moderate protein (12-14% for adults), and appropriate calcium (0.6-1.0%). Avoid pellets with colorful bits (sugary unnecessary additions), dried fruits, seeds, nuts, or corn—these cause obesity, digestive upset, and provide no nutritional benefit.
Young Champagne d'Argent under one year old receive unlimited alfalfa-based pellets supporting rapid growth to large adult size—growing to 10+ pounds requires substantial nutrition. Transition to timothy-based adult pellets around 6-8 months gradually over 7-10 days preventing digestive upset. Senior rabbits over 6-7 years may need slight pellet increases if maintaining weight becomes difficult due to decreased appetite or absorption, though hay remains unlimited always.
Fresh vegetables provide essential vitamins, minerals, variety, and additional hydration. Adult Champagne d'Argent should receive approximately 2 to 3 cups of fresh leafy greens daily (about 2 cups per 5 pounds, adjusted for their 10-11 pound average size) divided between morning and evening feedings. Large rabbits consume more vegetables overall than small rabbits providing important nutrients. Excellent daily choices include romaine lettuce (never iceberg which lacks nutrition and causes diarrhea), green and red leaf lettuce, butter lettuce, arugula, spring mix, cilantro, parsley, basil, mint, dill, carrot tops (leaves only, not roots which are high sugar), bok choy, and dandelion greens (pesticide-free only). Introduce new vegetables one at a time, waiting 24 hours between additions, monitoring carefully for digestive upset indicated by soft stool or diarrhea.
Rotate vegetable varieties regularly preventing monotony and avoiding potential problems from feeding identical vegetables repeatedly. Feed moderately (1-2 times weekly maximum): kale, spinach, collards, mustard greens, chard—due to higher calcium/oxalate content. Occasional vegetables: bell peppers (any color), cucumber, celery, small amounts of carrot root (high sugar). Leafy greens should predominate over other vegetable types.
Wash all vegetables thoroughly removing pesticides and dirt. Remove uneaten portions within 3-4 hours preventing spoilage and discouraging flies. Never feed wilted, moldy, slimy, or spoiled vegetables.
Fruits are treats only, offered sparingly due to high sugar content. Limit to 1-2 tablespoons once or twice weekly maximum per 5 pounds of body weight, so large Champagne d'Argent might receive slightly more than small rabbits in absolute amount but still very minimal. Appropriate fruits include small pieces of apple (remove all seeds—toxic), banana, blueberries, strawberries, raspberries, pear, melon. Avoid all dried fruits (extremely concentrated sugar). Use tiny fruit pieces as high-value training rewards.
Dangerous foods never to feed: chocolate (toxic theobromine), avocado (toxic persin), onions, garlic, chives, leeks (toxic causing blood damage), rhubarb leaves (toxic oxalic acid), iceberg lettuce (causes diarrhea), raw beans (toxic lectins), potato (high starch), tomato leaves and stems (toxic alkaloids), mushrooms (many toxic), all nightshade family plants, processed human foods, bread, crackers, cereal, candy, cookies, dairy products (rabbits are lactose intolerant), meat, eggs, pet foods designed for other species, commercial treat mixes containing seeds/nuts/corn/grains.
Water must be available 24/7 without exception. Large Champagne d'Argent drink substantial quantities relative to their size—expect them to consume significantly more water than small rabbits. Provide fresh water daily in heavy ceramic bowls (very heavy to prevent tipping—large rabbits can easily overturn lighter bowls) or hanging water bottles (use extra-large bottles appropriate for large rabbits). Many rabbits prefer bowls allowing natural drinking posture. Clean water containers daily thoroughly preventing bacterial growth, algae, and biofilm. Hot weather requires additional attention—add ice cubes or frozen water bottles to bowls maintaining cool, appealing water, and refresh multiple times daily.
Feeding schedules establish helpful routines. Many owners provide pellets once daily (morning) encouraging hay consumption throughout the day rather than filling up on pellets first then ignoring hay. Vegetables can be split between morning and evening offerings. Hay should be available constantly, absolutely without restriction—refresh twice daily even though substantial amounts should remain, as rabbits strongly prefer fresh hay and may ignore older portions.
Observe feeding behavior during every interaction—normal eager eating indicates good health. Any appetite changes warrant immediate veterinary attention within hours—do not wait to \"see if it improves.\" Even 12 hours without eating triggers life-threatening GI stasis risk in rabbits whose unique digestive systems require constant food passage.
Obesity prevention is critical for large Champagne d'Argent. Overweight large rabbits face severe, life-limiting complications. Maintain weight between 9-12 pounds depending on individual frame size, with easily palpable spines and ribs without prominent fat deposits, visible waists when viewed from above, and no fat deposits on chest or abdomen. If a Champagne d'Argent becomes overweight, gradually reduce pellets over 2-3 months, ensure unlimited hay access, significantly increase daily exercise opportunities. Never crash-diet rabbits—rapid weight loss causes potentially fatal fatty liver disease.
Monitor body condition monthly by feeling along spine and ribs, observing waist definition from above, and weighing on accurate gram-sensitive scales. Not all Champagne d'Argent should weigh identical amounts—some individuals naturally fall toward lighter end (9-10 pounds), others toward heavier (11-12 pounds) based on frame size, bone structure, and build. Assess individual body condition rather than forcing all rabbits to one specific weight.
Transition between diets gradually over 7-10 days minimum when changing pellet brands or hay types. Mix increasing proportions of new food with decreasing proportions of old. Monitor fecal pellets continuously during transitions—normal firm, round, plentiful pellets indicate successful transition; soft pellets, diarrhea, or decreased output indicate problems requiring slowing or reversing the dietary change immediately.
