Prediction of the metabolizable energy requirements of free-range laying hens
(Amer Soc Animal Science, 2016-01-01)
This experiment was conducted with the aim of estimating the ME requirements of free-range laying hens for maintenance, weight gain, and egg production. These experiments were performed to develop an energy requirement ...
Modeling energy utilization and growth parameter description for broiler chickens
(2005-09-01)
Two experiments were conducted to develop and evaluate a model to estimate ME requirements and determine Gompertz growth parameters for broilers. The first experiment was conducted to determine maintenance energy requirements ...
Modeling energy utilization in broiler breeders, laying hens and broilers
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2004-03-01)
The factorial approach has been used to partition the energy requirements into maintenance, growth, and production. The coefficients determined for these purposes can be used to elaborate energy requirement models. These ...
Energy education: breaking up the rational energy use barriers
(Elsevier B.V., 2004-07-01)
Human development is associated directly or indirectly with the energy use, and because of this the energetic sources were dealt with in the recent past, as fully available to human necessities. The reality shows that the ...
Modeling metabolizable energy utilization in broiler breeder pullets
(2003-03-01)
The objective of this study was to determine models for ME requirements for broiler breeder pullets using the factorial method. The influence of the temperature on maintenance ME requirements was determined by experiments ...
Energy requirements for growth of pubertal female Saanen goats
(Journal of Animal Physiology and Animal Nutrition © 2015 Blackwell Verlag GmbH., 2015-08-06)
Previous research on energy requirements of female Saanen goats, using the factorial approach, has not considered the specific requirements for maintenance and growth during the pubertal phase. Thus, the purpose of this ...
Energy requirements and efficiency of energy utilization in growing dairy goats of different sexes
(Elsevier B.V., 2020-01-01)
The aim of this study was to investigate the effects of sex on the requirements for maintenance and efficiency of energy utilization in growing Saanen goats. A database from 7 comparative slaughter studies that included ...
Energy education: Reflections over the last fifteen years
(2021-05-01)
Fifteen years after the publication of the article entitled “Energy Education: breaking up the rational energy use barriers” in 2004, what were the paths taken and scientific contributions made towards a rational energy ...
Applying the California net energy system to growing goats
(2019-02-26)
The aim of this review is to describe the main findings of studies carried out during the last decades applying the California net energy system (CNES) in goats. This review also highlights the strengths and pitfalls while ...
The limits of human development and the use of energy and natural resources
(Elsevier B.V., 2006-06-01)
The development of nations is an unquestionable requirement. A lot of challenges concerning health, education and economy are present. A discussion on these development models has occupied the minds of decision makers in ...
