| Abstract | Background Modified nano-montmorillonite is gaining attention as a feed additive for its benefits on ruminal fermentation. Chemical and mechanical methods were used to modify montmorillonite. Cetyltrimethylammonium bromide (CETAB) was utilized for chemical modification, while grounding was carried out to achieve the desired nanoscale particle size, resulting in the formation of the nanoscale powder known as MNMCETAB. Impacts of MNMCETAB supplementation on a basal diet, either contaminated with aflatoxin B1 (AFB1) or not at a level of 20 ppb were tested. Treatments included control (no supplements), a diet with 5 g per kilogram of dry matter (DM) of natural montmorillonite (NM), and diets with MNMCETAB at two doses, 0.5 (low) and 1 (high) grams per kilogram DM. Results The MNMCETAB showed better physicochemical traits than NM clay, including narrower particle size range, higher cation exchange capacity (CEC), greater specific surface area (SSA), and more functional groups. A significant linear decreasing effect (P < 0.05) of MNMCETAB addition on methane (CH) production was observed by the increasing level of the MNMCETAB clay. The control diet contaminated with AFB1 resulted in lower fiber degradability than the other treatments (P < 0.05). No variations were observed in ruminal protozoal counts by both clay supplementations, although there was a noticeable trend (P = 0.08) towards reduced protozoal populations due to AFB1 contamination. AFB1-contaminated diets showed indications of reduced (P < 0.05) levels of total volatile fatty acids (VFA), and concentrations of butyrate and propionate (P < 0.05), alongside shifts towards elevated (P = 0.006) acetate levels, while the low dose of MNMCETAB exhibited higher (P < 0.01) propionate concentrations than the other treatments. Conclusion These findings underscored the anti-methanogenic properties and the favorable impacts of MNMCETAB in mitigating the adverse impacts of AFB1on ruminal fermentation and nutrient degradability. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
