-The high nutritional content of rabbit meat is attributed to its proteins and fats. Because of the vitamins, minerals, and micronutrients, it also has a high biological value. By giving the rabbits pellets (Winner Rabbit concentrated food) along with hay, the nutritional content can be increased. The purpose of this study was to assess the effects on rabbit performance and organ measures of substituting 30, 50, and 100% of the food pellets for hydroponically grown Swiss chard or green barley fodder (HGBF) without reducing the animal's productivity during the fattening phase. A total of fifty-six thirty-day-old rabbits were fed seven different diets for 42 days. At the conclusion of the feeding period, the performance of the rabbits and several organs was measured. The ultimate weight of the rabbits was unaffected by substituting 50% concentrated chard or hydroponic green barley fodder (HGBF). Consequently, it was determined that one potential alternative to lower feeding costs in meat production systems would be to reduce concentrated chard or HGBF by 50% in rabbits during the fatting stage
