Consequently, rabbit meat enriched in these compounds is an excellent and functional food source for the human consumer. The rabbit meat total mineral content observed in G2, G1, and CG were 720.99, 681.75 and 603.71 mg/g, respectively, indicating a positive influence of rabbit dietary supplementation on meat quality, when considering nutrient content (see Table 3). To the best of the authors' knowledge, the dietary supplementation combinations and percentages employed in this study were first-investigated within this research field. However, the influence of various supplements (including linseed meal, fodder yeast, or selenium yeast) on rabbit meat quality and production indices has been investigated in several studies [41]. Previous studies have demonstrated that sole dietary supplementation with linseed meal in rabbit diets improves immune responses by reducing mortality. In those studies, dietary supplementation with linseed meal improved nutritional parameters, such as weight gain, mean daily weight gain, feed conversion rate, and significantly increased the level of polyunsaturated fatty acids in the meat of investigated rabbits [42; 43; 44; 45]. Additionally, studies conducted on feeding rabbits solely with yeast revealed increased productivity and reduced mortality. Dietary supplementation with yeast alone stimulates bacterial activity and balances the microbiota of the terminal gut, improving nutrient absorption, maintaining optimal pH and reducing the risk of nutritional deficiencies [46]. Several separate studies investigated the supplementing of rabbit feed with yeast. A most recent study, conducted in 2021, in Poland, evaluated the effect of selenium yeast supplementation at different feed ratios on the fatty acid profile of the liver and pulp muscle in rabbits [40]. The results revealed that selenium yeast administration significantly stimulated the accumulation of omega-3 fatty acids in the liver and muscle, proving that supplementation of the feed diet with selenium yeast improved rabbit meat nutritional value [44]. [PERSON] et al. (2018) investigated the effects of different concentrations of linseed meal on rabbit meat quality and lipid profile. The study was carried out on growing rabbits, for a fixed period and under controlled conditions. Their results revealed that linseed application decreased the levels of saturated fatty acids stored in the muscles, and significantly increased polyunsaturated fatty acid content, particularly for omega-3 and omega-6 fatty acids [47], consistent with the results of the present study (Table 2). The increase in polyunsaturated fatty acids with linseed application has been reported previously in other studies. [PERSON] et al. (2009) noted an increase in saturated and polyunsaturated fatty acids in rabbits fed a diet containing 3% linseed, with a 27.91% mean of omega-3 fatty acid content--compared to 23.75% in their CG group [48]. A previous study fed three groups of rabbits with separate diets, whereby the CG rabbits were fed a basal diet, and G2 and G3 groups were fed diets with 3.5% and 7% linseed contents, respectively. Their results revealed an increase in unsaturated fatty acids in the lower pulp muscle, on comparison to CG rabbits [49], due to the high alpha-linolenic and linoleic acid content in linseed and the low saturated fatty acids in the feed mixes, consistent with this study's results. In another study, rabbit groups fed high-fat feeds (linseed, linseed oil, or sunflower seeds) had lower saturated fatty acid values in comparison to other groups [50]. Several separate studies also revealed the effects of selenium supplements in rabbit diets, including selenium yeast, sodium selenite, and selenium-enriched algae. [PERSON] et al. (2010) concluded that selenium dietary supplementation in rabbits accumulated selenium in the musculature, improving meat quality [51]. Comparable results were obtained by [PERSON] et.al.
