It has been suggested that maximum sustained metabolic rate (SusMR) in mammals as reached, for instance, during lactation, is due to a limited capacity for heat dissipation. Here, we experimentally tested whether heat dissipation limitation (HDL) also constrains energy turnover in lactating European hares. Experimentally, we made use of the fact that hares nurse their young only once per day, w...

A nutritional evaluation of an Irish dairy herd indicated gross overfeeding of late lactation cows, over-conditioning of cows at parturition and a high rate of body condition loss in early lactation. Metabolisable-energy based nutritional modelling software was used to guide recommended dietary changes to prevent excessive condition gain in late lactation. Immediately following the implementati...

INTRODUCTION A six-year research program, “Premium Grains for Livestock”, funded by the Grains R&D Corporation, several animal R&D Corporations and Ridley Agriproducts is focussed on improving the quality of cereal grains for livestock. Cereal grains provide the major source of energy for animals raised in intensive production systems. However, the energy available from cereal grains can vary w...

an experiment was conducted to determine the effect of different inclusion rates and degree of saturation of fat sources on true metabolizable energy corrected to zero nitrogen retention ( tmen) values in broiler chickens at 42 days of age. animal fat and cotton seed oil were blended in the proportions of: 0.25:0.75 , 0.50:0.50 , 0.75:0.25. the three blends together with the animal fat and cott...

With the development of remote sensing technology, simultaneous acquisition 3D point cloud and color information has become constant goal for scientific research commercial applications in this field. However, since radar echo data practice refer to value spectral channel its corresponding energy, it is still impossible obtain accurate tristimulus values through integral calculation after tradi...

The objective of this experiment was to determine the digestible energy (DE) and metabolisable energy (ME) in 22 sources of soybean meal (SBM) produced from soybeans from different countries and subsequently to establish equations for predicting the DE and ME in SBM based on their chemical composition. The 22 sources of SBM were all processed in Chinese crushing plants, but the soybeans used or...

Thirty lactating Holstein Friesian cows were used in a three treatment randomised block design experiment to investigate the influence of degree of grass wilting prior to ensiling on animal performance and energy utilisation. The three forage treatments were produced from perennial ryegrass swards either ensiled directly or mown, conditioned, spread and tedded to ensure rapid wilting, and ensil...
