An experiment was conducted to evaluate the effects of feeding laying hens grains naturally contaminated with a combination of Fusarium mycotoxins. Parameters measured included performance, organ weights, and plasma chemistry. One hundred and forty-four, 45-wk-old laying hens were fed diets including: (1) control, (2) contaminated grains, and (3) contaminated grains + 0.2% polymeric glucomannan...

T_e high proportion of feed costs in total operating expenses (1,2,6) indicates that the utilization of feed by the birds is closely related to the profitability of >oultry operations. The relationship between feed conversion (expressed as a ratio between weight units of feed consumed per weight unit of product) and profitability (defined as an increment .of total income over total costs) is es...

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 ...

The aim of this study was to investigate the effect of wet feeding on feed conversion efficiency in laying hens during summer season. The study was carried out on 192 pullets of eight weeks age (distributed to four groups). The feed offered to chicks consisted of starter diet up to 8 weeks of age and grower diet up to 20 weeks of age. From 20 weeks onwards, birds were provided with layer diet u...

The effects of feed locations to the control of reactive distillation are explored. In this work, ideal reactive distillation systems are used to illustrate the advantage of feed trays optimisations in control. Because the temperature and composition profiles are critical for an effective utilization of the reactive zone, the optimal feed locations are essential for improved performance. Quanti...
