The New Progresses in Zn Requirements of Poultry
There were no considerable up to date on the trace element requirements of commercial poultry in recent years in despite of the progress in their performance traits. One of the more prevalent problems in modern broiler production system which could be attributed to the trace mineral inadequacy is skeletal disorders. Zinc, is an essential trace element which acts as a co-factor in several metalo...
متن کاملMetabolizable Energy and Chemical Composition of Poultry by-Product Meal
This study was conducted to determine the chemical composition and metabolizable energy of poultry by-product meal (PBPM) from two slaughterhouses in Iran. Samples were analyzed for dry matter, crude protein, ash, ether extract and gross energy. The amounts of calcium, phosphorus, sodium, potassium, Magnesium, Iron, Manganese, copper and Zinc were determined. The apparent metabolizable energy (...
متن کاملProtein and Amino Acid Requirements for Poultry
This fact sheet has been developed to support the implementation of the Natural Resources Conservation Service Feed Management 592 Practice Standard. The Feed Management 592 Practice Standard was adopted by NRCS in 2003 as another tool to assist with addressing resource concerns on livestock and poultry operations. Feed management can assist with reducing the import of nutrients to the farm and...
متن کاملMeeting the energy needs of poultry.
The most popular way is to evaluate the diet in terms of its metabolizable energy (ME) content measured in kcal ( I kcal=4-184 kJ). The problems associated with the determination of ME have been recently reviewed by Miller (1974). Unfortunately, the ME of a diet is not always equal to the sum of the ME values of its constituent parts (Vohra, 1972). It is reduced by the presence of toxicants, bu...
متن کاملEnergy requirements of infants.
OBJECTIVE To estimate the energy requirements of infants from total energy expenditure and energy deposition during growth. DESIGN Energy requirements during infancy were estimated from total energy expenditure measured by the doubly labelled water method and energy deposition based on measured protein and fat gains. SETTING Database on the total energy expenditure and energy deposition of ...
