in this study 60 arian male chickens for six weeks were used in a completely randomized block to evaluate the effect of three dietary energy level on performance and prevention ascites. diets energy levels were: as catalog; 100 and 150 kcal lower in starter and grower and finisher periods; 200 kcal and 300 kcal lower in starter and grower that catalog respectively. during the experiment, body w...

background: the performance and parasitology of semi-intensively managed west african dwarf (wad) lambs were evaluated following exposure to gastrointestinal helminth infected paddock and varied protein-energy feeds. methods: twenty four lambs obtained from the department of animal breeding and genetics and brought to directorate of university farm (dufarm) of federal university of agriculture ...

This paper presents an approach to analytically determine the most energy efficient toolpath strategy in mechanical machining. This was achieved by evaluating the electrical energy requirement of the NC codes generated for the zag, zigzag, and rectangular contour toolpath strategies. The analytical method was validated by performing pocket milling on AISI 1018 steel with the considered toolpath...

To control the quality of reverse osmosis (RO) product water and reduce operational costs and environmental impacts by increasing the system’s energy efficiency, it is necessary to identify the influence of process parameters on energy consumption and permeate water quality. This paper introduces a case study focused on the application of Design of Experiments (DOE) method in an industrial-scal...

One of the factors which are usually difficult to be measured in mills is the grindability and distribution of feed under real situation and in a short time. In the condition of achieving a fast and convenient way to determine these parameters, the proper relationship between energy, hardness and particle size distribution can be obtained. Feed hardness is one of the most important factors in g...

With the increasing installed capacity of desalination, the greenhouse gas emission for generating the required energy to power the desalination plants is also becoming the focus of attention in the world community. Domestic reverse osmosis membranes have been very successful technology especially in the developing world to provide safe drinking water. The novel concept of photovoltaic powered ...

Using a new-generation open-circuit calorimeter capable of monitoring the cost of activity, and thereby both the real thermic effect of feeding (TEF) and basal metabolism in free-moving freely-feeding rats, we have reassessed the proposal that when food intake is restricted an adaptative reduction in energy expenditure participates in the achievement of energy balance. Total energy expenditure,...

Feed is the greatest single cost factor in pig production. In pig diets, energy accounts for the largest proportion of the cost. Therefore, it is critically important that the energy content of a diet is characterized in the best possible way. There are several systems available for the characterization of dietary energy. The most common ones digestible and metabolizable energy describe the ene...
