In Australia, the process by which food energy factors are derived for food labelling purposes is under review. One of the questions of international relevance is whether energy factors should be derived using a definition of metabolisable energy (ME) or a definition of net (metabolisable) energy (NME), or some mixture of the two. ME describes the food energy available for heat production and b...

The dog chew studied here is a starch-based, twin-screw cooker extruded dog care and treat (C&T) product with oral health benefits. The manufacturing process and nutrient profile of such products are markedly different from those of main meal pet foods. Predicted metabolisable energy (PME) in pet food is calculated using equations derived from main meal feeding studies so it is unclear whether ...

The effect of feeding 0, 4, 8 and 16% rapeseed oil from 12-42 days of age was studied in broiler chickens on performance, digestibility of nutrients, and development of gastrointestinal tract, protein and energy metabolism. Thirty six female chickens (Ross 208) with initial body weight average 246 g were allocated to the four groups and kept pair-wise in metabolism cages. The chickens were fed ...

this experiment was carried out using 200 ross 308 broiler chickens in a completely randomized design with 5 treatments and 4 replicates. the true metabolisable energy of the barley hulls were determined using cecectomized roosters.the dry matter, true metabolisable energy, ash, ether extracts, crude protein, crude fiber, ndf, adf, ca and total p content of barely hulls were: 92%, 978 kcal/kg, ...

Feed represents more than 70% of the total cost of producing live broilers. In typical broiler feeds, more than 60% of the total cost is used to provide energy. Furthermore, it is generally agreed that broilers eat to satisfy energy requirement, therefore broiler feeds are normally formulated to provide all nutrients according to diet energy content. Therefore, it is critically important to kno...

the effects of different levels of whole cottonseed (wcs) on feedlot performance and morphology of small intestine were studied in a completely randomized design with four diets containing 0, 4, 8 and 16 percent wcs on 20 chaal male lambs for 90 days. the metabolisable energy and proteins contents of rations were equal. number and dimensions of different types of villi and depth of crypt gland ...
