SUCCESSFUL WEIGHT LOSS IS achieved through the creation of a negative energy balance, wherein the amount of energy taken in is less than the amount burned or utilized through physical activity and/or exercise. There are 2 factors to energy balance: energy intake and energy expenditure. Weight loss can only be achieved through modifying one or both of these factors. The focus of this report is o...

Studies on hospitalized elderly subjects have demonstrated that negative energy balance is common during hospitalization, but have concentrated primarily on long-stay and psychogeriatric patients. There is little information on energy balance in elderly patients admitted with acute illness from the community, despite the importance of this patient group and the presence of a number of factors l...

Achieving high dry matter intake (DMI) during early lactation is a major determinant of transition cow management success, as energy balance is tightly linked with reproductive performance (Butler and Smith, 1989) and aspects of health and immunity (LeBlanc, 2010). Although a common notion is that milk yield is the major driver of negative energy balance, several data summaries (reviewed by Gru...

nutrition has a significant effect on reproduction and lactation in ruminant. supply of require nutrient of dairy cows and ewes in early lactation is the main challenges that will be considered, since in most cases the animals facing negative energy balance after calving and the beginning of the period of lactation. negative energy balance may sometimes result in reduced livestock production an...

Several studies suggest that the $1.4 billion in government subsidies are encouraging the ethanol program without substantial benefits to the U.S. economy. Large ethanol industries and a few U.S. government agencies, such as the USDA, support the production of ethanol. Corn-farmers receive minimal profits. In the U.S. ethanol system, considerably more energy, including high-grade fossil fuel, i...

• Blood growth hormone (GH) concentrations increase shortly after calving. • Greater blood GH coordinates nutrient partitioning; the process through which nutrients are preferentially targeted for milk production. Blood insulin and insulin-like growth factor (IGF)-I remain low when blood GH concentrations increase. • Blood GH concentrations are elevated in cows in negative energy balance. Blood...
