A method is disclosed which is useful for elevating blood thyroid hormone levels in avian species (especially poultry species such as chickens, turkeys, ducks, quail, etc.) by implantation, injection, or supplementation of feed or water with thyroid hormones or thyroid-active substances (e.g., L-thyroxine, triiodothyronine, defatted and dessicated thyroid) to induce molting in order to extend egg production.

Methods for improved avian performance

A new method for identifying and eliminating chickens that are susceptible to pulmonary hypertension uses micrometer scale particles to occlude blood vessels in the lungs of the chickens. This results in the death of chickens that are pre-disposed to pulmonary hypertension. The invention effectively culls a chicken stock of the weaker animals.

Intra-vascular administration of particles to induce pulmonary hypertension, pulmonary hypertension syndrome, and ascites in poultry

A method of treating an avian egg, including the step of administering to an avian egg a sufficient amount of an L-arginine compound to prevent pulmonary hypertension syndrome in an avian to be hatched from the egg.

In ovo use of L-arginine and salts thereof in the prevention and/or

A method of treating or preventing pulmonary hypertension syndrome in avians, generally including administering a drinking water containing L-arginine compound to the avian.
