Pressurised Anaerobic Digestion for Reducing the Costs of Biogas Upgrading

Autor: Z. Liang, D. W. Wilkinson, C. Wang, S. J. Wilkinson

Publikováno v: BioEnergy Research.

The overall purpose of this study is to investigate the potential for producing higher energy biogas at elevated fermentation pressures. Upgrading of biogas is often carried out to increase its methane (energy) content by removing carbon dioxide. Upg

Precision feeding and precision nutrition: a paradigm shift in broiler feed formulation?

Broiler chickens grow rapidly, and their nutrient requirements change daily. However, broilers are fed three to five diet phases, meaning nutrients are under or oversupplied throughout production. Increasing diet phases improves production efficiency

Laying hens require substantial quantities of calcium (Ca) to maintain egg production. However, maintaining recommended dietary Ca through inclusion of limestone may impede nutrient digestibility, including that of other minerals. It was hypothesized

The multidimensional causal factors of ‘wet litter’ in chicken-meat production

Autor: Richard M. Stuetz, S. J. Wilkinson, Mark W. Dunlop, Peter H. Selle, Peter J. Groves, Amy F. Moss

Publikováno v: University of New England Australia

The problem of ‘wet litter’, which occurs primarily in grow-out sheds for meat chickens (broilers), has been recognised for nearly a century. Nevertheless, it is an increasingly important problem in contemporary chicken-meat production as wet lit

Severe feather-pecking in non-cage laying hens and some associated and predisposing factors: a review

Autor: K. M. Hartcher, S. J. Wilkinson, Greg M. Cronin, Paul H Hemsworth

Publikováno v: World's Poultry Science Journal. 72:103-114

Severe feather-pecking (SFP), whereby birds vigorously peck at and pull out the feathers of conspecifics, is an extremely injurious, highly prevalent behaviour. It has acute negative impacts on the...
