Viable bacteria were recovered from estuarine waters passed through a 0.2-mum polycarbonate membrane filter. The recovery method included the use of a dilute nutrient broth for primary enrichment followed by conditioning of the organism to a dilute nutrient solid medium. These bacteria were gram-negative rods and coccobacilli having an NaCl requirement and, upon initial culturing, low nutrition...

Feed represents the greatest single expenditure associated with poultry production. nutritional research in poultry has therefore centred on issues related to identifying barriers to effective digestion and utilization of nutrients, and on approaches for improving feed utilization. Poultry nutritionists have increasingly combined their expertise with that of specialists in other biological scie...

The 2011 Dietary Guidelines were developed with the aim of providing guidance on what dietary strategies can best address increasing rates of obesity and non-communicable chronic disease in Singapore. This set of dietary guidelines was developed with a local expert committee based on a review of scientific literature and data on current dietary patterns from the 2010 National Nutrition Survey. ...

Empirical and factorial methods are currently used to estimate nutrient requirements for domestic animals. The purpose of this study was to estimate the nutrient requirements of a given pig population using the empirical and factorial methods; to establish the relationship between the requirements estimated with these two methods; and to study the limitations of the methods when used to determi...

the nutrient requirements and performance guidelines of management guides are based upon many actual flock results obtained under good environmental and management conditions. in practice and under the prevalent poultry industry situation, through these nutrient levels, iranian farmers cannot attain the performance reported in management guidelines. an estimation of the model of broiler breeder...
