Studies on Turkey Body Composition

Specific Gravity, Carcass Fat, Abdominal Fat, and Yield Data in Broiler Chickens

“…Fat has a lower density than other components and when its proportion is increased the carcass density becomes less (Jones et al, 1978). For example, the specific gravity of turkey fat is .925 and the specific gravity of bony turkey wings is 1.036 (Moreng et al, 1963).…”

“…Their specific gravity readings averaged 1.059 for males and 1.058 for females with a range of 1.054 to 1.068. Moreng et al (1963), using medium size Bronze turkeys, found that the specific gravities of the eviscerated carcasses was 1.033 for males and 1.037 for females.…”

Factors Affecting Growth Response of Turkeys Administered Estradiol-17-Monopalmitate

“…There are two possible explanations why repeat implantations at 24 weeks resulted in a lack of response: (1) it is possible that the "pre-conditioning" of the birds to the EMP treatment at 16 weeks of age may have rendered them less responsive to the repeat treatment, (2) that if the original theory (Moreng et al, 1963) on age of bird and function of testes as a possible related interference in the function of the EMP holds true, then this response would be expected. The age of the bird in respect to sexual maturity may through testosterone production have masked the effects of this level of treatment.…”

The Effect of a Single Subcutaneous Injection of Estradiol-17-Monopalmitate on Growth in Turkeys

“…I T HAS been well established that synthetic estrogenic compounds such as diethylstilbestrol and dienestrol diacetate when administered to chickens or turkeys will result in increased weight gains and fat deposition (Lorenz, 1944(Lorenz, , 1954and Moreng et al 1963). Resulting improvement in fat deposition has been verified by many workers and residue studies extensively investigated; excellent reviews of the residue problem have been presented by and Umberger and Goss (1959).…”
