Assessing behavior in Aseel pullets under free-range, part-time free-range, and cage system during growing phase

Range-Free Localization

Advances in micro-electro-mechanical systems have triggered an enormous interest in wireless sensor networks (WSN). WSN are formed by large numbers of densely deployed nodes enabled with sensing and actuating capabilities. These nodes have very limited processing and memory capabilities, limited energy resources and it is envisioned that they will be mass produced, to reduce costs. Several chal...

Improve range-free localization accuracy in wireless sensor network using DV-hop and zoning

In recent years, wireless sensor networks have drawn great attention. This type of network is composed of a large number of sensor nodes which are able to sense, process and communicate. Besides, they are used in various fields such as emergency relief in disasters, monitoring the environment, military affairs and etc. Sensor nodes collect environmental data by using their sensors and send them...

The Antioxidant System in Broilers Is Altered under Free-range Conditions and Fed Restrictedly

Free-range birds exert substantial physical activity and are prone to adverse weather; these might increase the burden of reactive species in the body and hence initiate oxidative stress. Thirty-six one-day-old Ross 308 broilers were divided in 3 groups (12 birds each). The first group (I42) was kept indoors according to common rearing practices, and received a commercial feed ad libitum. The s...

First serologic survey of Q fever in free-range yaks in China

The objective of the present investigation was to determine the seroprevalence of Coxiella burnetii infection in free-range yaks in China. A total of 552 serum samples were collected from yaks in Gansu province, northwest China between April 2013 and January 2014, and antibodies against C. burnetii were evaluated using enzyme-linked immunosorbent assay (ELISA). Overall, 13.59% (75/552, 95% CI: ...
