O experimento foi desenvolvido objetivando-se avaliar o efeito da inoculação de estirpes de Streptococcus bovis (HC5 e JB1) sobre o pH, a produção de amônia e o valor nutricional em silagens de capim-elefante (Pennisetum purpureum Schum). O delineamento experimental foi o inteiramente casualizado, com três tratamentos: T1 - capim-elefante, T2 - capim-elefante inoculado com Streptococcus bovis HC5 e T3 - capim-elefante inoculado com Streptococcus bovis JB1, utilizando cinco repetições por tratamento. A menor concentração de amônia foi observada na silagem tratada com inoculante à base Streptococcus bovis JB1 (5,90 p.100 N-total). A inoculação aumentou os teores de ácido láctico e diminuiu os teores de ácidos acético, butírico e propiônico, sendo que as silagens inoculada com Streptococcus bovis JB1 e HC5 foram os que apresentaram os maiores valores de ácido láctico. Não houve diferença estatística para os teores de MS e PB. Para os valores das fibras, a silagem de capim-elefante inoculada com Streptococcus bovis JB1 apresentou o menor valor de FDN (59,77 p.100) e HEM (26,71 p.100). O maior valor da DIVMS foi observado na silagem com Streptococcus bovis JB1, mostrando superioridade de quatro pontos percentuais (64,23 p.100) em relação ao tratamento sem inoculante bacteriano (60,35 p.100). O uso Streptococcus bovis JB1 melhora o processo fermentativo além de promover melhorarias na qualidade da fibra e na DIVMS da silagem estudada.

Human bodies encompass very important symbiotic and mutualistic relationships with tiny creatures known as microbiota. Trillions of these tiny creatures including protozoa, viruses, bacteria, and fungi are present in and on our bodies. They play important roles in various physiological mechanisms of our bodies. In return, our bodies provide them with the habitat and food necessary for their survival. In this review, we comprehend the gut microbial species present in various regions of the gut. We can get benefits from microbiota only if they are present in appropriate concentrations, as if their concentration is altered, it will lead to dysbiosis of microbiota which further contributes to various health ailments. The composition, diversity, and functionality of gut microbiota do not remain static throughout life as they keep on changing over time. In this review, we also reviewed the various biotic and abiotic factors influencing the quantity and quality of these microbiota. These factors serve a significant role in shaping the gut microbiota population.

Abstract We present a comparison of woody browse availability and white-tailed deer (Odocoileus virginianus) use among clearcut interiors, skidder trail edges, and mature forest and an evaluation of the relative importance of aboitic factors in predicting browsing pressure within regenerating clearcuts in the central Appalachians of West Virginia. We sampled 810 1-m2 plots in or adjacent to nine regenerating clearcuts (8–19 ha) during the summer of 2001. Availability and use of woody browse did not differ between clearcut interior and skidder trail plots for any species observed. Plots in the adjacent mature forest had less woody browse availability and higher utilization. Overall use of available woody browse in clearcuts was >15%. Combining all woody species, elevation (wI = 0.618) and distance to mature forest (wI = 0.379) were more important than landform index, plot surface shape, aspect, and slope in predicting deer browsing pressure in regenerating clearcuts. We believe that without management activities aimed at reducing deer browsing, in many parts of this region the ability of forest managers to regenerate stands will be jeopardized and the forested ecosystem will be compromised.
