The effects of grain and carbohydrase enzyme supplementation were investigated on digestive physiology of chickens. A total of 625 one-day-old chicks (Ross 308) were randomly assigned to five treatments in a completely randomized design. Treatments included two different types of grains (wheat, and barley) with or without a multi-carbohydrase supplement. A corn-based diet was also considered to...

Maternal separation (MS) in neonates can lead to intestinal injury. MS in neonatal mice disrupts mucosal morphology, induces colonic inflammation and increases trans-cellular permeability. Several studies indicate that intestinal epithelial stem cells are capable of initiating gut repair in a variety of injury models but have not been reported in MS. The pathophysiology of MS-induced gut injury...

Background: Habitat characteristics can vary over small spatial scales at which gene flow is expected to swamp any effect of divergent natural selection. However, fine-grained (‘microgeographic’) adaptive divergence may still be feasible if individuals exhibit dispersal behaviours that improve the match between their phenotype and habitat. For example, threespine stickleback (Gasterosteus acule...

Certain euryhaline teleosts can tolerate media of very high salinity, i.e. greater than that of seawater itself. The osmotic gradient across the integument of these fish is very high and the key to their survival appears to be the enhanced ability of the gill to excrete excess NaCl. These fish provide an opportunity to study morphological and biochemical aspects of transepithelial salt secretio...

introduction corn and wheat are the grains most routinely used in commercial poultry diets. for consumption of these cereals, there are a competition between humans and mono-gastric animals. due to corn crop limitation in iran, approximately 50% of the corn required for poultry nutrition is supplied through imports. since triticale is more resistant to various diseases, dry weather and in simil...

Anchistus custos Forsk&l is the only common prawn commensal with bivalves of the family Pinnidae in Singapore waters. The whole morphology shows pronounced modifications connected with the commensal mode of life. The second legs are large and massive and show marked positive allometry in the male but appear to have little function in the general life of the animal. The animal occurs wherever th...

Alzheimer’s disease (AD) is a neurodegenerative disease that is the most common type of dementia.AD includes 60_80% of dementia and most people with AD have more than 65 years old.AD causes losing neuronal activity by abnormal proteins. Plaques of beta-amyloid and tangles of “tau” protein can lead to AD. Recently evidence has found that AD may come from outside of central nerv...

Hagfish feed by immersing themselves in the body cavities of decaying animals. This ensures a rich nutrient source for absorption via the gills, skin, and gut, but it may also subject hagfish to reduced levels of dissolved oxygen and elevated levels of the products of biological degradation. This study investigated the impacts of hypoxia and ammonia on the assimilation and metabolism of selecte...

The aim of this study was evaluate tissue lesions caused by black gill disease and its causes in 85-80 days old Litopenaeus vannamei with an average weight of 13-15 g located in the Delvar shrimp rearing site from Bushehr province. Primary and secondary gill lamella was necrosis, central axis were not arranged and gill lamella swelling, epithelial cell necrosis along with karyorrhexis and pykno...
