This paper, therefore, presents some values for feather follicle development of the Jilin White goose in China.
Observation of the feather follicle development At E10 the surface of the goose embryo was smooth and transparent, covered by a layer of mucous membrane.
Histological observations of the embryonic feather follicle patterning
Figure 2 showed morphological changes of feather follicle (longitudinal sections), and we compared them with those of chicken (Figure 2A-E).
Figure 6 showed results of changes in the primary and secondary feather follicle densities of different sampling sites at each age of embryonic stage.
At the same time, difference in feather follicle development between goose and chicken were clearly observed also.
Occasionally, primary feather follicles may remain at the surgical site, leading to abnormal feather growth, feather follicle cysts, or ingrown feathers.
One bird was completing a normal molt and had hemorrhage from each feather follicle immediately after treatment, which stopped quickly with the application of direct pressure.
The bird receiving the highest laser dosage demonstrated osseous necrosis and woven bone formation at primary feather follicle 10 on 1 wing.
Cryosurgery done by pulling the feather and placing the cryoprobe in direct contact with the feather follicle was also effective, but there was significant tissue swelling and areas of necrosis.
8) The diode laser was used in this study because of its superior tissue penetration and ability to cauterize the vascular tissue of a feather follicle.
Therefore, the cryoprobe probably was not in direct contact with the feather follicle for an appropriate amount of time to adequately freeze the tissue.
They are similar to basal cell tumors but are associated with feather follicles
Tissues identified in the mass included cartilage, bone, lung, trachea, renal tubules, feather follicles, keratin cysts, nervous tissue, smooth muscle, and glandular epithelium resembling intestinal mucosa (Fig 3).
Ectoderm was represented by feather follicles, tracheal and intestinal mucosa, and renal tubular epithelium.
