Background Coprophagy plays a vital role in maintaining growth and development in many small herbivores. Here, we constructed a coprophagy model by dividing rabbits into three groups, namely, control group (CON), sham-coprophagy prevention group (SCP), and coprophagy prevention group (CP), to explore the effects of coprophagy prevention on growth performance and cecal microecology in rabbits. Results Results showed that CP treatment decreased the feed utilization and growth performance of rabbits. Serum total cholesterol and total triglyceride in the CP group were remarkably lower than those in the other two groups. Furthermore, CP treatment destroyed cecum villi and reduced the content of short-chain fatty acids (SCFAs) in cecum contents. Gut microbiota profiling showed significant differences in the phylum and genus composition of cecal microorganisms among the three groups. At the genus level, the abundance of Oscillospira and Ruminococcus decreased significantly in the CP group. Enrichment analysis of metabolic pathways showed a significantly up-regulated differential metabolic pathway (PWY-7315, dTDP-N-acetylthomosamine biosynthesis) in the CP group compared with that in the CON group. Correlation analysis showed that the serum biochemical parameters were positively correlated with the abundance of Oscillospira, Sutterella, and Butyricimonas but negatively correlated with the abundance of Oxalobacte and Desulfovibrio. Meanwhile, the abundance of Butyricimonas and Parabacteroidesde was positively correlated with the concentration of butyric acid in the cecum. Conclusions In summary, coprophagy prevention had negative effects on serum biochemistry and gut microbiota, ultimately decreasing the growth performance of rabbits. The findings provide evidence for further revealing the biological significance of coprophagy in small herbivorous mammals.

| Actually, some consumers have displayed a growing preference for rabbit meat sourced from alternative rearing systems as opposed to intensive cage-based systems. This trial was designed to explore the influence of production systems (cages -Cg; 13.3 rabbits/m2, closed parks -CP; 7.7 rabbits/m2, and open-air systems -Oa; 0.25 rabbits/m2) and slaughter age (70 and 84 days) on the growth, carcass traits and meat quality of growing rabbits. 120 animals were randomly allocated to three different production systems. At both slaughter ages, the M. biceps femoris of Oa and CP rabbits exhibited higher cooking losses (5.50 vs. 3.83%) and total pigments (0.37 vs. 0.28 mg/g) compared to Cg rabbits. The production system did not significantly impact dressing out, visceral development, Warner-Bratzler Shear Force -WBSF and meat pH. In contrast, 84-day-old rabbits reared in cages displayed reduced digestive organ development, decreased caecal acetic acid and increased butyric acid concentration, compared to their counterparts. When comparing slaughter ages, the 84-day-old rabbits exhibited higher dressing out percentages, lower relative organ weights (liver, kidney, lung and heart), decreased hind part proportions and lower cooking loss values. Furthermore, the hind legs of these rabbits had a greater proportion of muscle and less bone, along with increased luminosity and reduced redness. In conclusion, production systems exert influence on specific carcass and meat characteristics.
