Abstract

Prickly pear (Opuntia ficus indica L.) could be used in rabbit nutrition in compliance with circular economy principles, global warming issues, and reduction of production costs. This study aims to evaluate the effects of dietary incorporation of prickly pear seed cake (PPSC) on growth, physiological, and histometric parameters in rabbits. A total of 105 rabbits were divided into three experimental groups (n = 35) and fed different diets: a commercial feed (C group), the same feed with alfalfa replaced by PPSC at 10% (10PP group), and at 20% (20PP group). They were group-housed in cages with 5 animals per cage from weaning until slaughtering. While body weights and weight gains were similar in all groups, the coefficients of nutrient digestibility of dry matter, fibers, and ashes, as well as the characteristics of intestinal villi, were improved in the 10PP group compared to the others (p < 0.05). The 20PP group showed a reduction in perirenal and interscapular fat (p < 0.05), as well as lower plasma concentrations of triglycerides and cholesterol compared to the C group (p < 0.001). In conclusion, PPSC can be incorporated into the diets of growing rabbits up to 20% as a partial substitute for alfalfa without the impairment of growth performance. Additionally, the inclusion of PPSC enhanced nutrient digestibility and increased the intestinal absorption surface area.

使用刺梨籽饼（Opuntia ficus indica L.）对家兔生长性能、消化率、生理和组织计量参数的影响

刺梨（Opuntia ficus indica L.）可用于家兔营养，以符合循环经济原则、全球变暖问题和降低生产成本。本研究旨在评估膳食中添加刺梨籽饼（PPSC）对家兔生长、生理和组织测量参数的影响。研究人员将 105 只兔子分为三个实验组（n = 35），分别饲喂不同的饲料：商品饲料（C 组）、同样的饲料，但苜蓿中添加了 10%（10PP 组）和 20%（20PP 组）的刺梨籽饼。从断奶到屠宰，它们被分组饲养在笼子里，每笼 5 只。虽然各组的体重和增重相似，但与其他组相比，10PP 组的干物质、纤维和灰的营养消化系数以及肠绒毛的特征都有所改善（p < 0.05）。与 C 组相比，20PP 组的肾周脂肪和肩胛间脂肪减少了（p < 0.05），血浆中甘油三酯和胆固醇的浓度也降低了（p < 0.001）。总之，PPSC 可作为苜蓿的部分替代品添加到生长兔的日粮中，添加量最高可达 20%，且不会影响生长性能。此外，添加 PPSC 还能提高营养物质的消化率并增加肠道吸收表面积。
