Reproduction in Female Animals

Reducing infertility in agriculturally important females, including aquatic species, is of major importance for efficient animal production. In dairy cattle and poultry, fertility of females has declined significantly for several decades. More knowledge is needed to improve fertility and facilitate implementation of integrated animal production systems that will contribute to sustainability of the animal production unit. This information will control or reduce animal production costs, provide product cost benefits to consumers, and may ultimately lead to increased productivity from fewer animals, thereby conserving natural resources and enhancing the environment. In addition, approaches to foster and manage animal reproduction are key to future application of assisted reproductive technologies and biotechnologies.

NIFA has supported a number of basic and applied projects at the systems, cellular, and molecular levels to enhance fertility in breeding populations or to develop monosex populations or sterile females for food production. Abstracts of these projects are available by clicking on the links below:
