The Protein Requirement of the Turkey Poult

Lysine and Protein Requirements of Bronze Turkeys

“…In fact, in one case they report superior growth to six weeks for poults fed an amino acid-supplemented simple 20 percent protein diet as compared to poults fed a 28 percent protein diet supplemented with amino acids, fish meal, meat scraps and dried brewers' yeasts. These findings support the reports of Baldini et al (1954). Klain, Hill and Slinger (1954), however, have shown that under their conditions growth was superior for poults fed diets containing 25.5 and 28 percent protein compared to a 21.8 percent protein diet supplemented with methionine and lysine.…”

“…In this respect, the results reported here differ from those of Baldini et al (1954) and Fisher et al (1956), but support the results reported by Klain, Hill and Slinger (1954) and Ferguson et al (1956). It should be observed that Klain et al and Ferguson et al used Bronze poults and that the rate of growth was comparable to that achieved in the experiments reported here.…”

“…It should be observed that Klain et al and Ferguson et al used Bronze poults and that the rate of growth was comparable to that achieved in the experiments reported here. Baldini et al (1954) and Fisher et al (1956) used Jersey Buff poults and it may well be that the slower gains of the poults in their experiments reflect a lower lysine and protein requirement for this variety.…”

Determination of the Limiting Amino Acids in Corn-Soybean Oil Meal Diets for Young Turkeys , ,

“…Thus, the results do not confirm those of earlier workers (Baldini et al, 1954;Fisher et al, 1956) that methionine and lysine are able to reduce the protein requirement from 28 to 20% protein. This difference is thought to be related to variations in effective protein requirement of larger vs. smaller type turkeys.…”

The Effect of Different Levels of Productive Energy, Protein and Methionine upon the Growth of Broad Breasted Bronze Turkey Poults

“…It could be that the capacity of the turkey to consume feed was limited so that the 24% and 26% levels of protein were not sufficient quantitatively to permit maximum growth. Baldini et al (1954) reported methionine as the limiting amino acid in a 28% protein, cornsoybean oil meal poult diet. The results in the present instance indicate that at the 24 and 26% protein level, with Calorieprotein ratios of 34 to 39:1, the energy level was too high for maximum growth.…”
