Growth of Broad Breasted Bronze Turkey Poults Fed a 26 Percent Protein Diet with Different Levels of Productive Energy

Studies on Energy Levels in Poultry Rations

“…Ferguson et al (1956a) in-dicated that the optimum Calorie-protein ratio for the turkey poult to eight weeks of age was between 25 and 31:1. In later work, Ferguson et al (1956b) using a 26% protein ration obtained the best growth of poults to eight weeks with a Calorie-protein ratio of 29:1. In later work, Ferguson et al (1956b) using a 26% protein ration obtained the best growth of poults to eight weeks with a Calorie-protein ratio of 29:1.…”

Supplemental Fats for Growing Turkeys: A Review

“…Evidence illustrating this response to added fat, however, is not as consistent as that showing the feed efficiency response. Ferguson et al (1956) reported that supplemental fat increased weight gains of poults significantly (P10.05). Ferguson et al (1956) fed a ration supplemented with 3.5 or 7% soybean oil to turkeys from 2 to 8 weeks of age.…”

Ferguson et al (1956) fed a ration supplemented with 3.5 or 7% soybean oil to turkeys from 2 to 8 weeks of age. The largest increase in weight gains occurred with the turkeys fed diets containing 3.5% soybean oil.…”

The Effect of Dietary Energy on the Protein Requirements of Growing Turkeys

“…The supplementation of the amino acids lysine plus tryptophan failed to give a growth depression at this protein level. Ferguson et al (1956) also noted that this growth depression was not present at the higher protein levels in the presence of methionine.…”

“…However, the most efficient feed conversion was obtained at the 34 percent protein level. Lockhart andThayer (1955) andFerguson~ al. (1956) reported that the most efficient feed conversion did not correspond to the greatest gain in body weight.…”
