Abstract One of the latest methods which can improve the accuracy of prediction and response to selection is the selection based on markers. Research has shown that the POU1F1 (Pit-1) gene has important role in the regulation of animal growth and associated with carcass, weight and milk traits. The purpose of this research was to study polymorphisms of POU1F1 gene and their association with...
Dynamic energy Budget (DEB) theory describes the rate of energy absorb by living organisms and use it for body protection, growth, and reproduction. The present study was performed on Alburnoides eichwaldii in Zarrin-Gol and Kaboudwal rivers (Golestan province). The results showed that the DEB growth model in the two rivers and the allocation of energy fraction for body maintenance (κ) was more...
Understanding insulin-like growth factor-1 (IGF1) biology is of particular importance because, apart from its role in mediating growth, it plays key roles in cellular transformation, organ regeneration, immune function, development of the musculoskeletal system and aging. IGF1 bioactivity is modulated by its binding to IGF-binding proteins (IGFBPs) and the acid labile subunit (ALS), which are p...
A growth experiment was conducted with juvenile fringed flounder (Etropus crossotus) from North Inlet (South Carolina, USA) to provide information on the growth of a small, shortlived flatfish with a subtropical and tropical distribution. The fringed flounder has a maximum life span of 1.5 y and its long spawning period from March through October complicates the determination of growth rates ba...
To determine the effects of feeding or starvation on resource allocation to body components during the reproductive cycle of Sphaerechinus granularis, sea urchins were placed in laboratory tanks and either fed ad libitum or starved during two different periods of their biological cycle, i.e. the mature stage and the recovery stage. The urchin growth was monitored over the whole experimental per...
