Protein and Energy Levels for Turkey Starting Diets

Energy and Protein Requirements for Turkey Starting Diets

“…These results agree with Atkinson et al (1957). Increasing protein and increasing energy improved performance in their experiments, with little evidence of interaction.…”

“…Atkinson et al (1957) reported a 28 percent protein diet with a "CP ratio" (productive Calories per pound per 1 percent protein) of 30 to 1 was required for optimum growth and feed efficiency to eight weeks. Atkinson et al (1957) reported a 28 percent protein diet with a "CP ratio" (productive Calories per pound per 1 percent protein) of 30 to 1 was required for optimum growth and feed efficiency to eight weeks.…”

The economic implications of supplemental fat usage in diets of growing turkeys

“…These authors observed that the weight gain improvement attributed to added fat could be obtained as long as dietary protein was maintained at an adequate level. This finding is in agreement with the reports by Atkinson et al (1957) and Donaldson et al (1958) that, unless protein levels were maintained adequately, added fat would not improve weight gains. Yacowitz et al (1956) reported slight improvements in weights of turkeys when rations supplemented with 3 or 6% tallow were fed from 9…”

Effectiveness of Unknown Growth Factors, Antibiotic, and Animal Fat in Turkey Poult Rations

“…The use of fat with higher levels of protein has consistently promoted increased growth in this laboratory (Waibel, 1956). Other workers reporting improved growth rate by turkey poults due to increased dietary protein and energy include Lockhart and Thayer (1955), Patterson et al (1955), and Atkinson et al (1957).…”
