“…This is in agreement with reports by Scott et al (1947), Blaylock et al (1954), Dymsza et al (1955), Lockhart and Thayer (1955) and Ferguson et al (1956). However, the best feed efficiency did not correspond to the greatest gain in weight.…”

“…The calculated energy to protein ratio in that study was 26.5 to 1. Ferguson et al (1956) reported a Calorie-protein ratio of 25:1 gave the best growth of poults with a 28% protein diet not supplemented with amino acids, but it was suggested by other results that this diet was apparently low in energy. These authors found that a 24.8% protein diet supplemented with methionine or methionine and tryptophane (Calorie-protein ratio 31:1) produced the optimum growth response.…”

“…Baldini and Rosenberg (1955) extended this work and showed that an amino acid, methionine, was required in greater amounts in the diets as the energy level of the diet was increased. Sunde (1956) showed that rations high in protein and low in energy reduced growth and efficiency of feed utilization.Although more work has-been done with chickens than with turkeys, several reports have recently been published concerning the optimum Calorie-protein ratio for turkeys (Lockhart and Thayer, 1955;Atkinson et al, 1956;Ferguson et al, 1956;and Waibel, 1956). In general these workers obtained best results when poults (0-8 weeks) were fed rations containing high levels of energy and protein, with the most desirable Calorie-protein ratio (productive choline and antibiotic +Bi 2 supplements to chicks.…”

Effect of feeding graded levels of fat with and without E XPERIMENTAL data have shown that there is a need for a suitable balance between energy and protein in poultry rations for optimum efficiency and that rations high in energy content tend to promote more rapid growth as well as better feed conversion (Scott et al., 1947;Biely and March, 1954;Combs and Romoser, 1955;Matterson et al., 1955;and Patterson, 1955). Baldini and Rosenberg (1955) extended this work and showed that an amino acid, methionine, was required in greater amounts in the diets as the energy level of the diet was increased.

Supplementary fat along with additional protein was necessary for optimum growth rate. At least part of the beneficial effect obtained from fat supplementation of poult rations can be attributed to increased density and its effect on palatability as evidenced by such reports as that of Pepper et al. (1956), who reported a beneficial effect as a result of adding fat to poult rations containing 28% protein. However, if the ration was pelleted, supplementary fat did not increase the growth rate. More recently, Donaldson et al. (1956) showed that the Calorie-protein ratio for chicks was influenced by the energy level of the ration, being narrow for low energy diets and wide for high energy diets. As the proportion of Calories from dietary fat to those from other sources increased, a wider Calorieprotein ratio was tolerated without adversely affecting growth.Growing turkeys (8-16 weeks) may be able to tolerate a greater range in the Calorie-protein ratio than poults, according to the results reported by Carter and Wyne (1956).

A series of studies was conducted to determine whether a low-protein corn-soybean meal diet would support growth of turkeys similar to that supported by a standard diet. Three treatments administered in a series of experiments included: basal diet with essential amino acids (EAA), NaHCO3, and glutamic acid added at the expense of sucrose to bring the total protein up to 28% (+GLU); basal diet with EAA, NaHCO3, and sucrose added to bring the total protein content to 22% (+SUC); and a 28% crude protein standard diet that meets or exceeds NRC recommendations using intact protein sources (ST). Essential amino acid levels used in the experimental diets were based on an estimated ideal protein ratio for turkeys. The basal diet contained 18.4% intact CP from corn and soybean meal. All treatments were isocaloric with 3,172 to 3,192 kcal/kg. In all trials, the birds receiving +GLU and +SUC had adequate growth and feed:gain responses compared to birds receiving ST. The low protein basal diet with appropriate amino acid supplementation will allow for amino acid titrations to determine digestible amino acid requirements.
