The effects of lighting program, ingredient particle size and feed form on the performance of broiler turkeys

Autor: R. M. G. Hamilton, J. Kennie

Publikováno v: Canadian Journal of Animal Science. 77:503-508

Two experiments were done to examine the effects of lighting program, ingredient particle size and feed form on the performance of female and male medium White turkey broilers. The poults (1200 initially of each sex) were randomly assigned, within se

Autor: K. A. Sanford, D. M. Nash, R. M. G. Hamilton, H. W. Hulan

Publikováno v: Canadian Journal of Animal Science. 76:377-383

The effect of dietary menhaden meal (MM) on production and egg yolk lipids of commercial White Leghorn hens was studied for 350 d. One hundred and ninety-two birds were given a corn-wheat-soybean diet that contained either 0, 4, 8, or 12% MM. Analysi

Autor: R. M. G. Hamilton, H. W. Hulan, D. M. Nash

Publikováno v: Canadian Journal of Animal Science. 75:247-253

The effect of dietary HM on plasma and egg yolk lipids of commercial White Leghorn hens was studied over 350 d. A total of 192 birds were given corn-wheat-soybean meal diets that contained either 0, 4, 8, or 12% HM. Analysis of plasma lipids at four

Effects of ingredient particle size and feed form on the performance of Leghorn hens

Autor: F. G. Proudfoot, R. M. G. Hamilton

Publikováno v: Canadian Journal of Animal Science. 75:109-114

In each of two experiments, 1536 Leghorn pullets from two commercial genotypes (A and B) were given diets that were in the form of either mash, crumbles or pellets. The cereal grains used in these diets were either finely or coarsely ground using a h

Effect of flame roasting on the nutritional quality of common cereal grains for non-ruminants and ruminants

Autor: Mary A. McNiven, P.H. Robinson, J. W. DeLeeuw, R. M. G. Hamilton

Publikováno v: Animal Feed Science and Technology. 47:31-40

The effect on nutritional quality of barley, corn, oats and wheat after flame roasting at three temperatures was evaluated. Batches of barley, corn, oats or wheat were flame roasted in a commercial propane heated roaster at 67, 100 and 133% of the ma

Effects of dietary barley level on the performance of Leghorn hens

Autor: F. G. Proudfoot, R. M. G. Hamilton

Publikováno v: Canadian Journal of Animal Science. 73:625-634

Three experiments were carried out to examine the effects of dietary barley level on the performance of Leghorn hens. A 4 × 2 factorial arrangement of treatments was used in exps. 1 and 2 where there were four dietary barley levels (0, 15, 30 or 60%

Autor: R. M. G. Hamilton, B. K. Thompson

Publikováno v: Canadian Journal of Animal Science. 73:465-469

Feed intake and egg measurements were recorded daily over a 56-d period from Leghorn pullets and force-molted hens, with 36 of each age. Meteorological conditions during the experiment were obtained from a nearby weather station. Regression analyses
