Abstract:

The presence of a normal and stable rumen microflora is an important indicator of rumen health in ruminants. It also plays an important role in the development of rumen morphology, microbial colonization, regulation of immune function, and resistance to invasion by exogenous pathogenic factors. Recent studies have shown that the composition of rumen microbes in neonatal ruminants is relatively simple. However, different microbial communities begin to colonize and occupy different niches during early rumen development, so nutritional interventions at this point may result in the formation of specific microbial communities and may have lasting effects. Such interventions provide a better long-term strategy for further improving ruminant productivity and health. In this paper, the latest research findings on early nutrition intervention in the development of the rumen microecological system are reviewed in detail from the following three perspectives: Exploring the development of rumen morphology and function of young ruminants, the factors affecting the early rumen microbial community colonization and the selection of a ‘window period’ for intervention, and brief analysis of the immune interaction between host and microbial communities. This information would help in the improvement of the performance of ruminants through early nutrition intervention to meet the global challenge of animal husbandry, as well as improvements in straw fiber utilization and the control of methane emission.

Key words: rumen microflora, early nutrition intervention, microbial colonization, immune interaction
