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.

夏季膳食添加干番茄渣粉对新西兰白兔生长性能、血浆代谢、肉品质以及肉和脂质健康指数的影响

夏季，将 120 只新西兰白兔 (NZW)（5 周龄；735.27 ± 27.23 克）饲养在开放式房屋中。本实验旨在评估补充干番茄渣粉（DTPP）对 5-13 周龄 NZW 兔的生产性能、血液代谢、胴体性状、肉质、血脂和健康指数的影响。四种处理是标准兔子饲料（对照）和分别补充0.5%、1.0%和1.5%DTPP的对照饮食。饲喂含有 1.5% DTPP 的饮食的兔子在 9-13 周龄期间表现出最高的生长率，尽管在 5-13 周龄期间采食量最低。最佳饲料转化率 (FCR) 是用添加 1.5% DTPP 的饲料喂养兔子 5-13 周记录的。日粮中添加 0.5% 或 1.0% DTPP 显着提高了调味品百分比、总可食肉含量、饱和脂肪酸 (SFAs)、单不饱和脂肪酸 (MUFA) 和多不饱和脂肪酸 (PUFA) 含量，以及 Σn - 6/Σn - 3 比率肉的总数为 n − 6。膳食补充 DTPP 可减少肾脏、腹部和背部脂肪。饮食中添加 DTTP 可以降低总胆固醇、甘油三酯和极低密度脂蛋白 (vLDL) 浓度。在饲喂添加 1.5% DTPP 的饲料的兔子中观察到肉中亚油酸、花生四烯酸和保水能力水平最高。含有1%和1.5% DTPP的日粮改善了肉类的致动脉粥样硬化和血栓形成指数、肉脂质量、所需脂肪酸/不需要的脂肪酸比率以及肉类健康指数。总之，高达 1.5% 的 DTPP 保持了兔肉的生长性能，通过增加维生素 E 提高了肉质，减少了脂肪沉积，改变了脂肪酸组成，并改善了兔肉的致动脉粥样硬化、血栓形成和低胆固醇指数。
