Modelling energy utilization in poultry
(Wageningen Acad Publ, 2010-01-01)
Models of daily energy requirement can help to establish better and more profitable feeding programs for poultry. Studies have been conducted at UNESP-Jaboticabal-Brazil with the aim of studying energy utilization in broiler ...
How heat stress (continuous or cyclical) interferes with nutrient digestibility, energy and nitrogen balances and performance in broilers
(2016-10-01)
The effect of continuous and cyclical heat stress on broiler growth performance, nutrient digestibility, energy and nitrogen balances was investigated. Four hundred and fifty, 21-day-old, Cobb male broilers were raised in ...
The imprint of crop choice on global nutrient needs
(Iop Publishing, 2014-08)
Solutions to meet growing food requirements in a world of limited suitable land and degrading environment focus mainly on increasing crop yields, particularly in poorly performing regions, and reducing animal product ...
Efecto de la actividad física sobre la ingestión de energía y nutrientes en mujeres jóvenes universitarias: un análisis bayesiano
Background: Physical activity is one of the main actions in order to reduce the prevalence of obesity. High performance sport increases energy consumption but there is no conclusive evidence about the effect of physical ...
Accuracy of nonlinear feed formulation for broiler chickens: maximising broiler profit
(2012)
The modeling technique is simple, useful and practical to calculate optimum nutrient density to maximize profit margins, using nonlinear programming by predictive broiler performance. To demonstrate the influence of the ...
Formulation of diets for poultry: the importance of prediction equations to estimate the energy valuesFormulación de dietas para pollos: la importancia de usar de ecuaciones de predicción para estimar los valores de energía

Energy, nitrogen, and phosphorus balances in grazing cattle fattening systems
(2019)
The aim of this work was to check the balance of energy, nitrogen, and phosphorus in pre-fattening and fattening bovine systems at Turiguanó Livestock Breeding Company, in the province of Ciego de Ávila, Cuba. The botanical ...
Nutrient use efficiency in interspecific hybrids of eucalypt1
(2016-07-01)
The aim of this work was to evaluate nutrient use efficiency in interspecific hybrids of eucalypt, as an aid in the development of forest breeding programs for areas with limited nutrients. To do this, five clones were ...
Net energy, protein and macrominerals requirements for 70 to 120 day old female rabbits
(Associação Francaise Cuniculture, 1998-01-01)
In order to determine the net energy, protein and macrominerals requirements of 70 to 120 day old, 52 female White New Zealand rabbits, weighing 1900g +/- 40g were used. At the beginning of the experimental period, 14 of ...
