The female reproductive tract is commonly referred to as oviduct in birds. The oviduct is a highly convoluted muscular duct, concerned with the transport of the ovum away from the ovary, with fertilization of the ovum and by the deposition of albumen, membranes and shell on to the ovum to form the finished egg [1]. Reproductive diseases in poultry causes high morbidity (35%), mortality (15%) an...

Concern for the welfare of the hen during an induced molt has been expressed by animal activists groups, poultry scientists, and commercial poultrymen in recent years. Most commercial laying hen molting programs utilize some length of feed removal to initiate a molt. These practices have raised some questions and concerns by the general public regarding the practice of removing feed from laying...

The Lohmann Selected Leghorn (LSL) and Lohmann Brown (LB) layer lines have been selected for high egg production since more than 50 years and belong to the worldwide leading commercial layer lines. The objectives of the present study were to characterize the molecular processes that are different among these two layer lines using whole genome RNA expression profiles. The hens were kept in the n...

There are few published studies describing the unique management practices, farm design and housing characteristics of commercial meat chicken and layer farms in Australia. In particular, there has been a large expansion of free range poultry production in Australia in recent years, but limited information about this enterprise exists. This study aimed to describe features of Australian commerc...

Several commercial software allow to model and simulate an architecture at the physical network layer. However, none of them allow simulating the operating scheme of a distributed object architecture. The aim of this article is to propose a methodology based on the DEVS formalism for the modeling and the simulation of distributed object architectures. We extend the classical “Waterfall” softwar...

The Decision Support System for Production of Commercial Layer was developed based on the demand analysis. VB .NET 2005 and SQL SERVER 2000 was used as main methods for system development. With this system, the data of alternation, growth, breeding, environment, immune for layer production can be recorded, edited, analyzed and be given by a report forms. With this system, the production efficie...

Increased Internet speeds together with new possibilities for tailor-made television services have spurred the interest in providing television via the Internet. Several television services are readily available and both IP-layer and application-layer (P2P) technologies are used. When disregarding commercial influences, customers will choose for IPTV or P2PTV based on the Quality of Experience ...

A compact commercial Doppler lidar has been deployed in Indianapolis for two years to measure wind profiles and mixing layer properties as part of project to improve greenhouse measurements from large area sources. The lidar uses vertical velocity variance and aerosol structure to measure mixing layer depth. Comparisons with aircraft and the NOAA HRDL lidar generally indicate good performance, ...

OBJECTIVES To find evidence, either corroborating or refuting, for many persisting beliefs regarding the feasibility of carrying out surgical randomised controlled trials with a placebo arm, with emphasis on the challenges related to recruitment, funding, anaesthesia or blinding. DESIGN Systematic review. DATA SOURCES AND STUDY SELECTION The analysis involved studies published between 1959 ...
