the effect of silver nanoparticles as additive on broiler performance was investigated through employed of 312 day-old broiler chiks (arbor-acre plus) in a completely randomized design with 6 treatment diets each in 4 replicates. corn- soy based diets were formulated for starter, grower and finisher according to nrc (1994) recommendations. the silver nanoparticle solutions (2000 ppm) were added...

aphanius ginaonis is exclusive to the geno hot spring, located in the hormozgan province. in this paper some biological aspects of aphanius ginaonis and contents of its digestive tract and its relation with cyanobacteria (blue-green algae) in the geno hot spring was examined. sampling was conducted monthly, samples were fixed in 5% formalin immediately after fishing and transferred to the ichth...

The human oro-gastrointestinal (GI) tract is a complex system, consisting of oral cavity, pharynx, oesophagus, stomach, small intestine, large intestine, rectum and anus, which all together with the accessory digestive organs constitute the digestive system. The function of the digestive system is to break down dietary constituents into small molecules and then absorb these for subsequent distr...

Lactation is the most energetically demanding period in the life cycle of female mammals, and its effects on digestive flexibility and the size of internal organs have been extensively studied in laboratory mice and rats since the early 1900s. However, there have been only two studies on this topic for wild rodent species. Here, we analyzed digestive flexibility--that is, changes in gut content...

The gastrointestinal (GI) tract is composed of a diverse set of organs that together receive extracorporeal nutrition and convert it to energy substrates and cellular building blocks. In the process, it must sort through all that we ingest and discriminate what is useable from what is not, and having done that, it discards what is "junk." To accomplish these many and varied tasks, the GI tract ...

effect of natural zeolites and nano-zeolite on gut flora, tibia bone characteristics, blood parameters and performance of broilers investigated with 336 male ross 308 broilers chicks allocated to   seven treatments with four replicates and 12 chicks per each. experimental treatments were control (no zeolite supplemented), natural zeolite (0.5, 1 and 1.5 percent) and nano-zeolite (0.5, 1 and 1.5...

Microbial community in gastrointestinal tract participates in the development of the obesity as well as quite a few metabolic diseases in human. However, there are few studies about the relationship between gut microbiota and porcine fatness. Here, we used high-throughput sequencing to perform 16S rRNA gene analysis in 256 cecum luminal samples from Erhualian pigs and 244 stools from Bamaxiang ...
