چکیده
Abstract The rumen microbiome has an important role in providing nutrition to ruminants, which is linked feed efficiency and environmental adaptability of ruminants. However, there no report about the influence different altitude regions on fermentation parameters microbiota Sanhe cattles. In this study, 20 ruminal fluid samples heifers were collected from Hulunbuir City, Inner Mongolia Autonomous Region (119°57 'E, 47°17' N; 700 m altitude, LAL) Lhasa Tibet (91°06'E, 29°36'N; 3 750 HAL), analyzed by gas chromatography high-throughput sequencing determine 16SrRNA gene. results showed that acetic acid/propionic acid high-altitude group was significantly reduced (P < 0.01), but significant differences other volatile fatty acids, pH, ammonia nitrogen > 0.05). composition bacteria at phylum level, high relative abundance Actinomycetes 0.05), increased Spirillum had effect Bacteroides, Firmicutes At genus Rikenellaceae_RC9_gut Ruminococcaceae_UCG-010 0.05); Ruminococcus_1 Olsenella Pseudobutyrivibrio 0.05) decreased significantly. Ruminococcaceae_NK4A214 Ruminococcus_2 have a downward trend (0.05 ≤ P 0.10). study revealed influenced function rumen, can provide some new insights mechanism adapting theoretical basis for nutritional regulation cattle areas.

The effects of a dietary challenge to induce digestive upsets and supplementation with yeast culture on rumen microbial fermentation were studied using 12 Holstein heifers (277 +/- 28 kg of BW) fitted with a ruminal cannula, in a crossover design with 2 periods of 5 wk. In each period, after 3 wk of adaptation to a 100% forage diet, the dietary challenge consisted of increasing the amount of gr...
متن کاملThe Effects of Use Medicinal Plants on Rumen Fermentation Parameters in Ruminants
Rumen is a persistent and specific ecosystem consists of bacteria, protozoa and fungus where feed fermentation takes place in it. Produced Hydrogen in rumen can be used in the synthesis of the volatile fatty acids and the microbial protein and its excess would be eliminated through the production of Methane by methanogenesis. Nutritionists have tried to find ways to decrease loss and energy and...
