Sixteen growing crossbred Anglo-Nubian goats, 10-12 months old, pre-experimental average body weights of $18.3{\pm}0.28kg$ were randomly allotted to four diets to investigate the efficiency of utilisation of diets containing increasing levels of desiccated coconut waste meal (DCWM) in the tropical environment of Samoa, South Pacific region. The four diets were designated as 1, 2, 3 and 4. Diet 1 that has no DCWM served as the control, while diets 2, 3 and contained different levels of DCWM. Voluntary concentrate intake, growth rate, feed efficiency and nutrient digestibility coefficients were measured. Gross energy (GE) and organic matter (OM) values of the diets increased linearly with increase in the levels of DCWM in the diets. Voluntary concentrate intake decreased with increasing proportion of DCWM in the diets. Forage intake increased with increase in the levels of DCWM diets offered to the growing goats. Total voluntary feed intakes were statistical significant (p<0.05) and the goats on diet 4 had the least intake followed by those on diet 3. Goats an diets 1 and 2 were different in total feed intake but not at a significant level (p>0.05). Feed efficiency (FE) followed the trend of voluntary concentrate intake and daily live weight gains. Dry matter digestibility (DMD) was significantly different (p<0.05) among the goats offered the different diets. DMD improved with increasing levels of DCWM. The goats accepted all, the diets that were compounded with the different levels of dried DCWM and this seems to suggest that DCWM have no deleterious effects. However, the best level at which dried DCWM could replace brewers dried grains in the diets of growing goats is at 38.5% (diet II). Based on voluntary feed intake, live-weight gain and apparent nutrient digestibility coefficients of the goats it could be concluded that DCWM based diets merits further attention as a locally available feed source in ruminants nutrition in the Pacific Island countries where feed availability is seasonal.
A Jabber-Based Management Framework for Heterogeneous Sensor Network Applications

The continuously increasing diffusion of application scenarios requiring pervasive data sensing has lead to the development of novel monitoring solutions leveraging on Heterogeneous Sensor Networks (HSNs). At the moment, only little attention has been dedicated to the design of multi-purposes applications devoted to process, filter and use data from HSNs and aimed at providing composite services to the final users. Most available networks are currently managed by custom stand-alone applications, where many low level details are handled at application level. Actually, this approach presents many drawbacks in terms of system flexibility and adaptability. In such a scenario, the main goal is to decouple application logic from low level implementation details including the HW/SW platform and the programming language. Moreover, the specific units of functionality should be organized into autonomous and connectable modules operating in a distributed computing environment. This paper presents a management framework for rapid and flexible deployment of HSN-based applications based on XMPP/Jabber, a well-known XML-based open-source Instant Messaging protocol. The proposed solution aims to speed up the integration of different software modules into a network of services. The main benefits of the proposed solution include an increase of code reusability, platform independency, system scalability and modularity. The advantages of the proposed approach are demonstrated by presenting three use-cases.
