“…These data indicate that the limitation of protein intake in groups 1 and 2 was the motivating force in the reduction of body weight since group 3 that was limited in energy alone grew as rapidly as the toms in group 4 receiving the control diet. These results are in agreement with those of Summers et al (1968) who found that level of protein influenced weight gain regardless of dietary energy level, and Voitle et al (1972) who observed that toms receiving a protein-restricted diet were 36-38 percent lighter than the controls at 24 weeks of age. On the other hand, Anderson et al (1963) restricted feed intake (energy and protein) of toms from 12 to 24 weeks of age and noted significantly reduced body weights, and also Touchburn and Brown (1972) who found energy and protein restricted birds to weigh 73 to 83 percent of their full-fed counterparts at 26 weeks of age.…”

A study was conducted to investigate the effect of early dietary restriction of protein and/or energy on the subsequent reproductive ability of the tom. One hundred 8-week old Large White turkey toms (April hatch) were placed at random into four floor pens of 25 each and fed the following diets: group 1, 20.6% protein with 2,4 Mcal. M.E./kg. diet 8-12 weeks, 15.3% protein with 2.68 Mcal. 12-16 weeks, 10.4% protein with 2.85 Mcal. 16-24 weeks; group 2, 20.3% protein with 2.9 Mcal. 8-12 weeks, 14.8% protein with 2.98 Mcal. 12-16 weeks, 9.8% protein with 3.27 Mcal. 16-24 weeks; group 3, 22% protein with 2.4 Mcal. 8-12 weeks, 18.9% protein with 2.57 Mcal. 12-16 weeks, 16.3% protein with 2.81 Mcal. 16-24 weeks; group 4 (control), 22% protein with 2.91 Mcal. 8-12 weeks, 19% protein with 3.03 Mcal. 12-16 weeks, 15.9% protein with 3.17 Mcal. 16-24 weeks. Beginning with the 25th weeks all toms received a 14.3% protein diet with 2.8 Mcal. The restriction of energy significantly reduced the percentage of males producing semen, and the restriction of energy significantly reduced the percentage of males producing semen, and the restriction of energy and both protein and energy significantly depressed semen volume per male in comparison with the average produced by the control males. Other reproductive traits were not affected by early dietary controls.

“…In each case where full-fat soybeans were used, incorporation was to the maximum extent respective of the esti-mated protein requirements for the period (Summers et al, 1968). It should be noted that the high levels of soybeans used during the early periods to meet absolute estimates for protein resulted in associated energy being greater than that on which the requirement was originally determined (Summers et al, 1968). It should be noted that the high levels of soybeans used during the early periods to meet absolute estimates for protein resulted in associated energy being greater than that on which the requirement was originally determined (Summers et al, 1968).…”

This experiment evaluates the effect of decreasing dietary CP, in addition to the effects of dietary supplements of L-Thr to low CP diets, in Large White Nicholas toms from 0 to 18 wk of age. Toms were fed dietary treatments consisting of four levels of dietary CP as a percentage of NRC (1994) recommendations (100, 92, 84, and 76% of NRC recommendations). Additional treatments consisted of supplements of L-Thr (0.1 and 0.2% of diet) added to the 92 and 84% NRC CP treatments. All eight dietary treatments were formulated to meet a minimum of 105% of NRC (1994) recommendations for Met, TSAA, Lys, Thr, and Trp. Body weight, feed conversion, mortality, and carcass composition responses were measured. Decreasing CP to 84% of NRC resulted in 18-wk BW lower than that (P < or = 0.001) of toms fed diets containing 100 or 92% of NRC CP; however, toms fed 84% of NRC CP diet supplemented with 0.1% L-Thr had 18-wk BW equal to (P < or = 0.001) that of the 100 and 92% NRC CP treatments. Toms fed diets containing 76% of NRC CP had depressed BW and feed:gain in comparison to all other treatments. No adverse effects in cumulative feed:gain (0 to 18 wk) were noted by decreasing CP from 100 to 84% of the NRC recommendations. Mortality did not differ among treatments. Treatments had no effect on carcass fat expressed as a percentage of hot carcass weight. Breast meat yield (deboned Pectoralis major and Pectoralis minor) was highest (P < or = 0.001) in toms fed the 100 and 92% NRC CP treatments. The 84 and 76% NRC CP treatments resulted in decreased breast meat yield regardless of L-Thr supplements. These results indicate that diets containing Met, TSAA, Lys, Thr, and Trp at a minimum of 105% NRC recommendations may support favorable breast meat yield when CP is decreased to 92% of the NRC (1994) recommendation. If growth and feed conversion are the desirable traits, rather than breast meat yield, CP levels below 92% of the NRC (1994) recommendation may support favorable responses.
