“…Digestion can occur in the crop and conceivably could alter AME values, but comparisons between conventional and Farrell-type AME data suggest that any effects are small. (Morris et al 1932;Panda and Combs 1950;Scott et al 1954;Mraz et al 1956; Richardson et al 1958). A small negative AME value was obtained for cellulose by Potter et al (1960), Anderson and Hill (1955) obtained a value of zero, and small positive values were obtained by Anderson et al (1958) and Sibbald et al (1960bSibbald et al ( , 1961b.…”

The importance of knowing the bioavailable energy (BE) content of poultry feedingstuffs is discussed in terms of economics, feed intake and the environment. The partition of ingested dietary energy is described and the effects of nutrient intake and of the microflora of the alimentary canal are outlined. Indirect biological, physical and chemical assays for BE are described and appraised. Procedures common to several direct bioassays for BE are discussed and points to consider in choosing between total excreta collection and the use of an indicator are presented. Assays for digestible energy, apparent metabolizable energy, true metabolizable energy and net energy are described. Variables affecting estimates of BE such as bird type, assay environment, assay diet and intake, assay design, the nitrogen correction, and metabolic plus endogenous losses are considered and a bioassay is recommended. The review concludes with brief speculation about future developments in the field of feedingstuff evaluation. Key words: Review, Energy, Assays, Methodology, Bioavailable

“…The efficiency of feed utilization is not necessarily sacrificed, but may actually be improved when fiber is added to high energy diets. Mraz et al (1956) indicated that the energyvolume ratio may be a better criterion of the growth promoting quality of the diet than other characteristics such as density, productive energy-weight ratio or fiber content.…”

“…Hammond and Bird (1941) stated that variability may be increased by any defect in diet which prevents normal development. Decreasing coefficients of variation in chicks at 4 and 8 weeks of age 1396 H. ZUCKER, J. C. ATKINSON, R. B. SCHNELL AND G. A. DONOVAN were reported by Mraz et al (1956) as a result of decreasing fiber or increasing energy; both dietary changes were accompanied by growth improvements. Atkinson et al (1954) obtained smaller coefficients of variation for average weights in turkeys from 8-28 weeks of age as a result of antibiotic supplementation.…”
