Standardized total tract digestible phosphorus requirement of 6 to 13 kg pigs fed diets without or with phytase

Animal, 2019
Dietary phosphorus concentration greatly affects pig’s growth performance, environmental impact and diet cost. A total of 1080 pigs (initially 5.9 ± 1.08 kg) from three commercial research rooms were used to determine the effects of increasing ...

Improving the Quality of Hydroxyapatite Ashes from the Combustion of Meat-Bone Meal in an Industrial Rotary Kiln

Energies, 2023
Research on the properties of hydroxyapatite ashes from an industrial unit burning meat and bone meal in an industrial rotary kiln is presented. High carbon content (10%), relatively low phosphorus (34%), and sulfides were found.

Characterisation of Local Bone Ash for Bone China Production

Jurnal Teknologi, 2013
Clay body can be defined as a mixture of clay or other minerals to achieve a specific purpose in the production of ceramics. Among the types of clay that can produce white translucent ceramic products is porcelain. 'Porcelain' is derived from Italian word porselino which means 'piglet'. It is said that the name was given based on a cowry shell which is

Regulation of bone phosphorus retention and bone development possibly by related hormones and local bone-derived regulators in broiler chicks

Journal of Animal Science and Biotechnology, 2021
Background Phosphorus is essential for bone mineralization in broilers, however, the underlying mechanisms remain unclear. We aimed to investigate whether bone phosphorus retention and bone development might be regulated by related hormones and local ...
