Abstract
One hundred and twenty New Zealand White rabbits (NZW) (5-week-old; 735.27 ± 27.23 g) were kept in an open-sided house during the summer season. The experiment aims to evaluate the impacts of dried tomato pomace powder (DTPP) supplementation on rabbits' performance, blood metabolites, carcass traits, meat quality, and lipid and health indices of NZW rabbits during 5-13 weeks of age. The four treatments were a standard rabbit feed (control) and the control diet supplemented with 0.5, 1.0, and 1.5% DTPP, respectively. Rabbits fed a diet containing 1.5% DTPP showed the highest growth rate through weeks 9-13 of age despite having the lowest feed intake spanning 5-13 weeks. The best feed conversion ratio (FCR) was recorded in rabbits fed with 1.5% DTPP-supplemented diet for 5-13 weeks. Diets supplemented with 0.5 or 1.0% DTPP enhanced markedly dressing %, total edible flesh, saturated (SFAs), monounsaturated (MUFAs), and polyunsaturated fatty acid (PUFAs) contents, as well as the ∑n - 6/∑n - 3 ratio and the total n - 6 of meat. Dietary supplementation with DTPP decreased kidney, abdominal, and back fat. Diets supplemented with DTTP decreased total cholesterol, triglycerides, and very low-density lipoprotein (vLDL) concentrations. The greatest levels of linoleic acid, arachidonic and water-holding capacity in meat were observed in rabbits fed 1.5% DTPP-supplemented diets. Diets containing 1 and 1.5% DTPP improved meats' atherogenic and thrombogenic indices, meat lipid quality desired fatty acids/undesired fatty acids ratio, and meat health index. Conclusively, DTPP up to 1.5% maintained the growth performance of rabbits, boosted meat quality through increasing vitamin E, reduced fat deposition, modified fatty acid composition, and improved atherogenic, thrombogenic, and hypocholesterolemic indices of rabbit meat.

Abstract
The objective of this study was to observe the effects of Rosa roxburghii Tratt seed (RRTS) on growth performance, meat quality, and sensory characteristic parameters in rabbits. Ninety-six New Zealand White rabbits were allotted to four dietary treatments containing 0 (CON), 120 (LR), 240 (MR), and 360 mg/kg (HR) RRTS. The experimental period lasted for 11 weeks. Thirty-two fattened rabbits were slaughtered, and the Longissimus thoracis et lumborum (LTL) muscle was used for analyses. The feeding of RRTS was significantly (P < 0.05) decreased the feed conversion ratio (FCR). pH45min, pH24h, lightness, redness, drip loss, and percentage of water loss were unaffected (P > 0.05) by dietary treatments, whereas MR and HR treatments resulted in lower (P < 0.05) levels of yellowness and higher (P < 0.05) levels of shear force. LR showed significantly higher (P < 0.05) meat polyphenol compounds and vitamin E relative to the CON. Moreover, compared to the CON, HR treatment showed significantly higher (P < 0.05) vitamin C and glutathione peroxidase, and LR and MR displayed lower (P < 0.05) superoxide anion radicals, and all treatments had higher levels catalase (CAT). C18:2n-6 t, C20:2, C20:3n-6, C20:4n-6, C20:5n-3, C22:5n-3, and C22:6n-3 in LTL meat were higher (P < 0.05) in MR than CON rabbits. Moreover, the LTL muscle sensory evaluation parameters of appearance and fibrousness were improved (P < 0.05). Overall, dietary supplementation with RRTS is a valid strategy for decreasing FCR, and improving meat CAT concentration, C20:5n-3 and C22:5n-3 profiles, and sensory characteristics parameters of rabbits.

Abstract
This study evaluated the effects of dietary supplementation of tomato processing by-product extract (TPBE) on growth performance, carcass characteristics and antioxidant status of growing rabbits under high ambient temperature. A total of eighty weaned New Zealand White (NZW) male rabbits (6-weeks-old; initial body weight, 730.28 ± 36.05 g) were randomly assigned to 4 groups. The first group was the control without supplementation; while the other groups were fed diets supplemented with 100, 200 and 250 mg TPBE/kg. The results showed that TPBE contained 211.85 mg/100g as total phenols and total flavones of 303.36 mg/100g. Rabbits fed a 250 mg TPBE-supplemented diet showed the heaviest body weight, the lowest feed intake and the best feed conversion ratio. TPBE diets reduced mortality percentage. Dietary supplementation of 250 mg TPBE had the highest dressing percentage. Plasma total protein, globulin, catalase and glutathione peroxidase of rabbits fed diets supplemented with 200 and 250 mg TPBE were high. Plasma total cholesterol, triglycerides, plasma hydrogen peroxide and malondialdehyde concentrations were decreased with dietary levels of TPBE. Rabbits fed 250 mg TPBE had higher T-AOC than the other groups. TPBE supplemented diets improved net revenue and economic efficiency. Conclusively, TPBE is containing appreciable content of polyphenols and flavonoids and the dietary supplementation of TPBE (250 mg/kg diet) had a positive impact on growth performance, reducing mortality and enhancing the antioxidant status of rabbits reared under high ambient temperature.
