The specific binding of vitellogenin to chicken oocyte membranes was characterized. This major hen serum phospholipoglycoprotein and one of its lower-molecular-weight components, phosvitin, bound to oocyte membranes with KD values of approx. 6 x 10-7 M. The optimum pH for binding was 6.0, the same as the pH of yolk contents. Phosvitin and vitellogenin compete with each other for binding; other ...

In the laying hen, very low density lipoprotein (VLDL) particles contain large amounts of apolipoprotein (apo)-VLDL-II in addition to apoB. These triglyceride-rich lipoproteins are transported from the liver primarily to growing oocytes. Since no appreciable hydrolysis of triglyceride occurs during this transport, we have investigated the possibility that apoVLDL-II functions as an inhibitor of...

The egg yolk of immunized chicken is a rich and inexpensive source of specific polyclonal antibodies. In this paper we show that 20-30 micrograms of a highly conserved mammalian protein, as exemplified by proliferating cell nuclear antigen, are sufficient to induce an immune response. Immunoblot analysis revealed that specific antibodies appeared 20 days after immunization, reached a plateau af...

Haplorchis  taichui is parasitic heterophyidae(trematoda) which lives in the intestinal mucosa of its main host and producing heterophyidosis,which is a zonootic diseases.subsequent to the authors, provious  studies which were made on parasit,s lift  cycle in nature in Khuzestan province,Iran,this experimental study was performed with the aim of establishing the parasite,s lift cycle in laborat...

<p><strong>Background. </strong>Poultry production is a tool for livelihood improvement and poverty alleviation in the developing countries. Indigenous chickens are numerous but lower egg performance than exotic Ethiopia. <strong>Objective</strong>. To compare yield, feed conversion ratio (FCR), mortality, quality traits of Normal feathered local (LL), Sasso-RIR (S...

This study presents a life cycle assessment (LCA) comparing laying hen to broiler chicken production. Sustainability and protein conversion efficiency are considered. The protein-to-protein was calculated per 1t of feed consumed by birds 1 kg in end products for human consumption. Additionally, part the commercial replaced live black soldier fly larvae, reared on Gainesville diet, fruit vegetab...

In Indonesia, the formulation of Anti-Monopoly Law was motivated by an agreement between International Monetary Fund (IMF) and Government Republic Indonesia. However, with IMF not only reason for drafting law. Even though Indonesia already has anti-monopoly law, it still practices monopoly in doing business. For example, monopolistic carried out 12 hen holding companies. sentenced to a total Rp...

Abstract In recent years, feature selection is becoming more and important in data mining. Its target that reduce the dimensionality of datasets while at least maintaining classification accuracy. There are some researches about chicken swarm optimization algorithm (CSO) applied to selection, effect extraordinary compared with traditional intelligence algorithms. However, there a complex search...
