Dairy compost (DC) was evaluated as a possible bedding substrate for brooding turkeys. This study compared livability, weight gain, and footpad score between pine shavings (PS) and DC for 2 strains of turkeys. There were no significant differences in

The purpose of this study was to examine embryonic mortality in turkey eggs from hens of two ages and to report values that minimize the error of wrongly distinguishing between early embryonic mortality (EEM, Days 1 to 7 of incubation) and unfertiliz

SUMMARY Embryonic growth relationships exist for egg weight, eggshell conductance, and length of the incubation period. These relationships have been well established for comparisons of embryonic development across species; however, very little is kn

A study was conducted comparing ovary and oviduct development following photostimulation in two lines of turkey breeder stocks (female line and male line). Birds were euthanatized for assessment of reproductive organ morphology at 3-d intervals follo

The influence of feed allowance during rearing was investigated in male-line Large White breeder hens. A flock of 200 poults was reared from 4 to 28 wk of age under four treatments as follows: full-fed controls (FF), lowprotein diet (12% CP from 12 t

Turkey toms were reared under short days [either 8 h light (L): 16 h dark (D) or 12L:12D] and photostimulated by transfer to 14L:10D between 7 and 22 wk of age. Photostimulation between 12 and 15 wk of age initiates semen production at 18 to 20 wk of

Turkey eggs were incubated at high altitude (1,700 m). Hatchability, hematology, and growth data were analyzed for the following treatments: 1) eggs receiving supplemented oxygen (SO) during the 1st wk of incubation (control eggs received no SO durin

Turkey eggs (Meleagris gallopavo) were incubated at altitude of 1,707 m to test the effects of oxygen supplementation and increased eggshell permeability by removal of shell cuticle on embryonic hematology. Turkey embryo hematological indices measure

Factors of Fick's First Law of Diffusion were manipulated in order to observe their effect on the hatchability of turkey eggs at high altitude. Shell permeability was studied by removing the eggshell cuticle. The eggshell surface for gas exchange was
