A Comparison of Eastern Wild Turkeys and Rio Grande Wild Turkeys in Northeastern South Dakota
… habitats of South Dakota. Rio Grande wild turkeys (Meleagris gallopavo intermedia) were successfully introduced into northeastern South Dakota in 1972-73, and reached peak populations in the middle 1980s. However, wild turkey populations have declined greatly in northeastern South Dakota …

Transcriptional regulation of the prolactin gene in turkeys
Poor reproductive performance by turkey hens compared with chickens is partially due to the early cessation of egg production associated with the onset of incubation behavior. Prolactin (Prl) is involved in the induction and maintenance of incubation behavior in birds, and understanding the …

Effects of Simulated Cold and Warm Transport on Turkeys
… with two 28°C treatments, and 30% or 80% RH. Turkeys were crated at 83 kg/m2 and exposed to conditions for 8 hours before processing. Three replications (8 birds) were performed per treatment for each gender, and between-sex comparisons were made within treatments. Significance was declared at …

Bioavailability of phosphorus from various sources for young turkeys
Three series of experiments were conducted to determine the relative bioavailability of various phosphate products with an emphasis on the defluorinated phosphates. In Series I, phosphorus in commercial mono/dicalcium phosphates, commercial dicalcium phosphates, commercial defluorinated phosphates, …

Epidemiology and Pathophysiology of Clostridial Dermatitis (Cellulitis) in Turkeys
… is a multifactorial disease of rapidly-growing turkeys. Clostridium septicum (Cs) has been identified as the primary cause, although C. perfringens (Cp) has also been implicated. Pathogenesis is not fully understood; however, it is hypothesized that Clostridia translocate from the …

Overwinter survival of wild turkeys on central Virginia's industrial forests
Overwinter survival of wild turkeys on industrial forests managed for short-rotation pines (treatment) and typical Piedmont forests and farmland (control), was investigated in Virginia's central Piedmont during 1986-1988. Ninety-six percent of the turkeys (N =106) were captured in early fall with …
