Abstract Rabbit as one of the Non-ruminant livestock (monogastric animals). The rabbit was chosen as the animal of choice in the present study because it is easily to use this animal in the laboratory experimentation. The present study investigated the pathological effects of emitted methane inside the large intestine due to feeding rabbits on highly fibrous green diet. Rabbits were allocated in four groups. The first group served as a control group involved 10 rabbits fed for 3 weeks on a balanced diet (dry feed and green leaves feed). In the other 3 groups, included green leaves diet (Group II), the commercial rabbit feed group (Group III) and silver nanoparticles loaded on commercial rabbit feed group (Group IV). Obtained results indicated that, feeding rabbits with the balanced diet produced no pathological lesions in all segments of the large intestine. In addition nearly all forms of the pathological alterations were recorded in the mucosa of the five studied parts of the large intestine of rabbits fed on pure green leaves diet for 3 weeks. Also, feeding rabbits with the dry commercial diet (group III) exhibited no pathological alterations. On the other hand, feeding rabbits with silver nanoparticles loaded on dry rabbit’s commercial diet displayed no pathological perturbations in the mucosa of the large intestine. Finally, the diets containing high percent of green leaves or fibers should be diminished to a large extent to minimize as possible the emission of greenhouse gases affecting global climatic changes. At the same time, avoiding such diets, especially those of pure green leaves, aimed in reducing the pathological alterations in the large intestine. A balanced diet of dry grains or rabbit’s pellets may be ideal in this concern. |
