Research has shown that dairy cows fed legume silages consumed more dry matter (DM) and produced more milk than those receiving grass silages. However, across northeastern U.S. dairies, legumes only contributed to 26% of grazed forage. Research to improve legume persistence while closing knowledge gaps about which legume-grass mixtures are best suitable for producing profitable milk (i.e., higher butterfat and protein) is needed to make organic and conventional dairies in New England more competitive in the long run.

In farming, a ‘summer slump’ refers to the periods of the growing season when traditional forage plants—eaten by livestock—don’t grow well or aren’t readily available. Scientists with the New Hampshire Agricultural Experiment Station are helping identify what forage crops could be grown to supplement traditional forages during these seasonal ‘slumps.’

A study from UNH suggests that black bears may provide a buffer to allow gray foxes to coexist with predators like coyotes, who compete with the fox for food and space.

Until recently, the organic grass-fed (OGF) management systems have had little research directed to identifying best practices for higher milk production. Andre Brito, a scientist with the NH Agricultural Experiment Station and associate professor in the Agriculture, Nutrition and Food Systems department, was one of several Northeast scientists to contribute to a paper in Renewable Agriculture and Food Systems journal that studied management techniques of OGF dairy farmers.

Aquaculture researchers at the UNH College of Life Sciences & Agriculture are investigating new and innovative methods of sustainable fishing, reducing prevalence of aquatic animal disease, and leveraging the many ecosystem services that marine life can provide.

In a study involving over 8,900 Hispanic/Latino adults, UNH researchers found that greater consumption of short and medium chain saturated fatty acids—primarily from milk and cheese products—was associated with better overall cognitive function.

New research on the Eastern oyster (Crassostrea virginica) show that both farmed and wild oyster filter nitrogen from the water, processing the element in their shells and soft tissues and helping reducing cases of eutrophication. In a recent paper, scientists showed that oysters and other shellfish can help complement land-based nutrient management practices, such as upgrades to wastewater treatment plants around New Hampshire’s Great Bay estuary to reduce nitrogen output.

The bobcat, New Hampshire’s official state wildcat and a critical contributor to the sustainability of the state's forest ecosystem, may be being stressed out by human activity in residential and agricultural areas.

With over 700,000 pounds produced and $2.3 million in farm sales, strawberries are an important crop for New Hampshire farmers. But improving the cultivated strawberry through breeding is particularly challenging. The cultivated strawberries has four times as many chromosome sets as humans, animals and most other crops, which significantly increases its genomic complexity. Research to untangle the plant's genetic structure will enable scientists to more quickly and effectively develop cultivated strawberry varieties that help New England farmers be more resilient and successful.

A New England cottontail hiding in its native shrubland habitat
Biological Sciences | Resource Category | College of Life Sciences and Agriculture, Natural Resources and the Environment | Resource Category | College of Life Sciences and Agriculture, New Hampshire Agricultural Experiment Station | Resource Category | College of Life Sciences and Agriculture, Peer Reviewed Journal Articles
An unintended impact of land-use changes over the past century has been a more than 86 percent decrease in the range of the New England cottontail. Ongoing habitat restoration efforts will help the survival of the New England cottontail, and new research by COLSA researchers finds that these efforts will also benefit at least 12 shrubland-obligate bird species with which the cottontail shares its habitat.
