46 major buildings and numerous greenhouses are constructed on 12,671 acres.

Significant new funds are available to "conduct research into the laws and principles underlying basic problems in Agriculture in its broadest aspects."

Because of this Act, many research projects at Beltsville change from a very applied to a more basic approach. These projects received about a 10% increase in funding.

Releases from the 1930's onward include the first dwarf Easter lilies, the first summer blooming dahlias and chrysanthemums.

Cultivar development continues today as consumer preferences change.

Return to top of page Photo: Beltsville small white turkey, 1940s In response to the need for a smaller, meatier turkey, scientists begin developing a new type of bird. By the late 1940's, the Beltsville small white turkey, which averaged 8-10 pounds with a high percentage of breast meat, begins showing up in stores.

This turkey line is part of the pedigree of nearly every turkey sold in the U.S. today.

This discovery alone increases the hatchability of eggs from 65% to the current 85%, providing an annual savings of 600 million eggs valued at $60 million.

A vaccine is developed to prevent hog cholera, a disease that costs producers more than $100 million a year. By 1978, hog cholera is eradicated in the U.S.

Phenothiazine, an effective and economical drug for removing many worm parasites from horses, swine, sheep, goats, and poultry, is discovered.
