A unique property of the avian oviduct is to store sperm for a prolonged period. The sperm storage tubules (SST) are located in the utero-vaginal junction of the oviduct, where sperm can be stored and survived for a few weeks after insemination or natural mating. The immune system in the oviduct is ...

The aim of present study was to determine whether the expression of transforming growth factor-βs (TGFβs) in the utero-vaginal junction (UVJ) of hen oviduct was changed by the stimulation with sperm. Localization of immunoreactive TGFβ3 (irTGFβ3) in the UVJ that contained sperm storage tubules (SST)...

The nutritional value of khesari (Lathyrus sativus), a grain legume, was determined for growing and laying pullets. Chemical analyses indicated khesari to be high in crude protein (283g/kg) and low in fat (12.0g/kg) with estimated true metabolizable energy concentration of 12.0MJ/kg. Four hundred Sh...
