The formation and regulation of vertebrate endogenous intestinal microbiota has been widely studied as the microbiota plays a crucial role in the host nutrition, development, and health. Despite the importance of microbiota for host health, it is still unclear whether the endogenous intestinal microorganisms are genetically distinct or whether they are genetically related with each other in dif...

the increasing susceptibility of broiler chickens to ascites syndrome has coincided with a continuing genetic and nutritional improvement in their feed efficiency and growth rate. ascites is multifactorial and interactions between environmental and endogenous factors play a particularly important role. the selection of fast growing broilers for high feed efficiency, which is characterized by hy...

investigation into total phenolics and their spectrum in the buds and corms of saffron crocus and a study of polyphenol oxidase changes in the apical bud during different stages of growth and development showed that changes in the growth and development of the apical bud may be related to changes in the composition of phenolics in the corm. a sudden intense change in content and kind of phenoli...
