Comparative study of the gut microbiome potentially related to milk protein in Murrah buffaloes (Bubalus bubalis) and Chinese Holstein cattle.

ABSTRACT: Previous studies suggested a close relationship between ruminant gut microbes and the mammary gland. In this study, shotgun metagenomic sequencing was used to reveal the differences in the intestinal microbiome potentially related to milk components in Murrah buffaloes and Chinese Holstein cattle. A PCoA based on the weighted Unifrac distances showed an apparent clustering pattern in the structure of intestinal microbiota between buffalo and cattle. We could attribute the structural difference to the genera of Sutterella, Coprococcus and Dorea. A further analysis of microbial functional features revealed that the biosynthesis of amino acids (including lysine, valine, leucine and isoleucine), lipopolysaccharide biosynthesis and cofactor/vitamin biosynthesis were enriched in the buffalo. In contrast, dairy cattle had higher levels of pyruvate metabolism and carbon fixation in photosynthetic organisms. A further correlation analysis based on different milk components and the typical microbiome uncovered a significant positive correlation between milk protein and the microbial biosynthesis of amino acids, which was also positively correlated in the genera of Parabacteroides, Dorea and Sutterella. This study will expand our understanding of the intestinal microbiome of buffalo and cattle as representative ruminants, as well as provide new views about how to improve the production and nutritional qualities of animal milk.

Project description:Traumatic pericarditis (TP) remains a serious problem facing bovine producers; particularly in the developing countries; causing severe economic losses. This study was carried out on 47 buffaloes including; control buffaloes (n = 20) and buffaloes with TP (n = 27) at Assiut governorate, Egypt. All animals were subjected to thorough clinical examination, whole blood profiling, blood serum biochemical assays, and radiographic and ultrasonographic examinations. The recorded ultrasonographic findings included; the contractility, contour and shape of the reticulum, shape and size of the heart and spleen involvement. All data were statistically analysed. Buffaloes with TP showed lymphocytic leucocytosis, increase in serum activities of AST, hyperproteinaemia, hypoalbuminaemia and hyperglobulinaemia. Radio-opaque metal foreign bodies, cardiomegaly and loss of the normal cardiac shape and contour were the most common radiographic findings in the diseased buffaloes. Ultrasonographically, the diseased buffaloes showed either acute pericarditis (n = 10) or chronic suppurative pericarditis (n = 17). Complete cessation of reticular contractions (0/3 min) and displacement of the reticulum from the diaphragm by a distance about 2.6-4.5 cm were the most common ultrasonographic findings of both types of pericarditis. In addition, the reticulum had uneven contour and the heart showed characteristic changes in its size, shape and contractility that was either accelerated or reduced. Reticular abscesses and peritoneal effusions were also imaged in all diseased buffaloes. In acute TP; the affected heart was enlarged with strong and clear cardiac contractions. Accumulation of hypoechoic fluids interspersed with echogenic deposits of fibrin within heart tissue and pericardium was observed. In chronic suppurative pericarditis, cardiomegaly, thickening of the cardiac wall and loss of the characteristic recognisable heart shape were the common ultrasonographic findings. Accumulation of hypoechoic fluids (usually pus) interspersing with echogenic deposits of fibrin within the pericardium, ventricles, atria and valves was also observed. In conclusion, ultrasonography with the aids of other diagnostic tools such as clinical findings, laboratory analysis and radiography has a high efficacy in evaluation of diseased buffaloes with TP.
