“…Buffalo is an important livestock resource in many regions of the world. Studies have shown that buffaloes are more tolerant of roughage compared with cattle, and the buffalo feces recovery of acid detergent lignin (ADL) is 88.90% which is lower than that of chromic oxide (Cr 2 O 3 ) (95.89%) and acid‐insoluble ash (97.14%) in roughage digestibility experiments using indicator methods [16]. These results may be related to the lignin‐degrading bacteria of buffalo rumen [17].…”

The purpose of this study was to isolate lignin‐degrading bacteria from buffalo rumen and to explore their interactions further. Using lignin as the carbon source, three bacteria, B‐04 (Ochrobactrum pseudintermedium), B‐11 (Klebsiella pneumoniae), and B‐45 (Bacillus sonorensis), which have shown lignin degradation potential, were successfully isolated and identified from the rumen fluid of buffalo by colony morphology, 16S ribosomal RNA gene sequencing, and biochemical and physiological analyses. The degradation rates of lignin were determined, and the maximum values were 4.86%, 11.1%, and 7.68% for B‐04, B‐11, and B‐45, respectively. The maximum laccase activities were 0.65, 0.93, and 1.15 U/ml, while the maximum lignin peroxidase activities were 5.72, 8.29, and 18.69 U/ml, respectively. Pairwise interaction studies showed inhibitory interaction between B‐04 and B‐45, inhibitory interaction between B‐04 and B‐11, and symbiotic interaction between B‐11 and B‐45. This is the first report on the lignin degradation ability of bacteria isolated from the buffalo's rumen, which provides a new understanding for revealing the mechanism of roughage tolerance of buffalo.

“…The dry matter intake (DMI) calculation formula was DMI = feed intake (kg/day) × DM content of the feed (%). Assuming a fecal recovery of acid-insoluble ash (AIA) is 100% [27,28], the fecal OM content was calculated by measuring the crude ash content in the feces. Apparent Total-tract digestibility (ATTD) for DM, OM, NDF, and ADF was calculated in a group as ATTD% = 100…”

Worldwide, silage is considered the main component in dairy animal diets; however, this portion is mainly dominated by corn silage, which raises availability challenges in some agricultural production systems. The present study evaluated a partial replacement of corn silage with forage rape silage (FRS) and its effect on feed intake, nutrient digestibility, rumen fermentation, milk production, and blood metabolites in buffalo. Thirty-six lactating buffaloes were randomly assigned to four different groups, according to supplementation of FRS (only corn silage, FRS0) or with 15% (FRS15), 25% (FRS25), and 35% (FRS35) of forage rape silage instead of corn silage. The results showed that, compared to corn silage, forage rape silage has a lower carbohydrate but a higher protein concentration. The buffalo intake of dry matter and organic matter were improved linearly with the FRS increasing in the diet. The apparent total-tract digestibility (ATTD) of dry matter, organic matter, nitrogen, neutral detergent fiber, and acid detergent fiber also increased by the FRS supplementation compared with FRS0. Conversely, FRS supplementation decreased the propionic, butyric, and valeric acid contents and increased the acetic:propionic ratio and microbial protein content. Furthermore, FRS inclusion led to a significantly higher milk urea and non-fat milk solid content, higher blood glucose, total globulins, blood urea nitrogen, and lower blood high-density lipoprotein. These results suggested that FRS has high a nutritional value and digestibility, is a good feed resource, and showed favorable effects when supplemented with dairy buffalo ration.
