In France, about 95% of the fatty liver production comes from mule ducks, an infertile hybrid cross between female common ducks (Anas platyrhynchos) and Muscovy drakes (Cairina moschata). As a hybrid, genetic improvement of the performance of mule ducks is achieved by selection of the parental populations. Feed represents two-thirds of the total costs of duck production; thus, the breeders’ mai...

Feed efficiency has a major influence on the unit cost of beef cattle production. Gibb and McAllister (1999) have reported that a 5% improvement in feed efficiency has an economic impact four times greater than a 5% improvement in average daily gain. In addition, the cost of feed is second only to fixed costs in importance to the profitability of commercial beef operations (Basarab, 1999). The ...

Plant proteins are plausible fishmeal substitutes but are deficient in some essential amino acids (EAA) like lysine and methionine. Combination of different plant proteins with complimentary EAA could be useful alternative. Bambaranut (Voandzeia subterranea) contains high amount of lysine while methionine is in sesame seed (Sesamum indicum). This experiment tested effects of combining sesame se...

A 75 days feeding trial was conducted to evaluate the influence of dietary supplementation of multi-strain (Bacillus sp.) probiotic (22×109 CFU/g) on growth and hematological parameters of Barbonymus gonionotus. A total 270 uniformed size (length 2.40±0.16 cm and weight 4.25±0.01g) fishes were equally and randomly distributed in nine (three treatments each with three replication) glass aquaria ...

Studies were conducted to determine the effects of high dietary ascorbic acid (vitamin C) on growth performance and body composition of a commercially important Asian catfish, Clarias batrachus. During experimental trial in the laboratory condition, the change in growth and feed utilization by the Clarias batrachus fed on three different Vitamin C level have been assessed by the determination o...

The Design of hexagonal patch is presented withsingle coaxial feed namelysimple hexagonalpatch,hexagonal patch with one triangular slot in ground for circular polarization. The circular polarization of two antennas are obtained with 1.31% axial ratio(AR) for simple hexagonal patch, 4.43% axial ratio hexagonal patch with slotted ground hexagonal patch antenna. The impedance band widths of these ...
