https://doi.org/10.1007/978-1-4757-0034-3 conditions and energy metabolism..In order to study surface temperatures in relation to climatic conditions, the accuracy of the measurements is very important. Especially point to point variations, differences according to direction and stimula created by the measuring instruments themselves have to be taken into account.

Energy Metabolism of Farm Animalsce..Utilization of feed energy involves energy losses with faeces, urine, combustible gases and heat. A survey is given on how and to what extent feed energy is converted into metabolizable energy (ME) and how efficiently the ME is utilized for maintenance, work and synthesis — growth, milk, eggs wo

Adaptation to, and Energy Costs of, Tethering in Pregnant Sowsosts. However, compared to group-housing, tethering has been reported to lead to an increase in MR and blood corticosteroid levels, and to reduce the immune response and health status of sows, factors which may decrease productivity. Tethering has also been associated with the development of behavio

Metabolic Rate of Piglets between Sucklingsn was measured in an indirect calorimeter of 0.085 m. with 2 animals (1 to 4 days of age) or individual animals (after 4 days of age). They were allowed to suckle about each hour. Mean metabolic rate was 672 kJ/kg./day. It appears that at 6–14 days of age metabolic rate was highest. There was a clea

Influence of Some Environmental, Animal and Feeding Factors on Energy Metabolism in Growing Pigsnvironment. Also feed intake and its use for maintenance and production can be changed. Housing itself may alter maintenance requirements by influencing activity and effective environmental temperature. Many experiments have been conducted to measure environmental/nutritional energetics of swine. At
