Effect of genotype on heat production and net energy value of a corn-soybean meal-based diet fed to growing pigs
energy utilisation genotype growing pigs heat production net energy
2015/10/9
The net energy (NE) system takes into account the metabolic utilisation of energy and has been proposed as a superior system for characterising the energy value of feeds. In growing pigs, the ineffici...
Earlier Metabolizable Energy Intake Level Influences Heat Production during a Following 3-Day Fast in Laying Hens
Net Energy Metabolizable Energy Laying Hens Heat Production Fasting Indirect Calorimetry
2016/5/11
The present study was conducted to estimate energy requirements for maintenance in laying hens by using indirect calorimetry and energy balance. A total of 576 28-wk-old Nongda-3 laying hens with dwar...

heat production physical activity ambient temperature feeding level laying hen
2009/7/31
Eight Single Comb White Leghorn laying hens were used to investigate the effects of feeding levels (FL), ad libitum and 40% feeding, and physical activities on heat production (HP) under different amb...
Comparison of the Effects of Thyroxine and Triiodothyronine on Heat Production and Skeletal Muscle Protein Breakdown in Chicken
chicken heat production muscle protein breakdown thyroxine triiodothyronine
2009/7/29
Effects of exogenous thyroxine (T4) and triiodothyronine (T3) were compared on heat production and skeletal muscle protein breakdown in broiler chickens aged from 15 to 27d. T4 and T3 were mixed in t...
