Feed accounts for 75 percent of the total expense of animal production. As the second most expensive ingredient in animal diets, protein supplement represents 25 to 30 percent of the total feed cost. The most commonly used feed protein supplement is soybean meal, which is added at 20 to 30 percent in diets for swine and poultry. In the United States, approximately 6 million metric tons of soybean meal is used only for pig feeding per year.
Cornell University Cooperative Extension-NYC (CUCE-NYC) modified, tested, and delivered an outdoor adventures-based ‘Scavenger Hunt Exploration’ to educate the public and the New York Harbor School student body about the ecology, natural landscape, culture, and history of Governors Island, the Hudson River and the New York Harbor, involving a group of NY Harbor School secondary students as assistants.
Dairy researchers are convinced that relatively high fiber digestibility is essential for high milk production. Harvest management decisions for spring forage harvests are critical given the small range in optimal fiber content (NDF) to make silage for lactating dairy cows.
We know that the order Cypriniformes is an incredibly diverse group of freshwater fishes with great variation in their life histories, morphologies, behaviors and physiologies. Many people are very interested in these fishes for research purposes; for their conservation status, diversity and evolutionary relationships; as well as for personal aquaria.
We are evaluating whether a network of drilling gas wells into the Marcellus Shale and their associated infrastructure development in the Southern Tier of New York will impede natural populations from accessing the habitat they require for their survival.
The objectives of the project are to:
1. Project the loss of forest habitat to well, pipeline, and road development over the next 20 years under a variety of possible scenarios of well development;
We developed a web-based tool that growers can use to better match nitrogen fertilizer amount and timing with corn crop requirements for maximum production.
Our goal was to develop a searchable adaptive web-based tool to aid students and external stakeholders to access information about the identification and use of woody plants in the landscape. To accomplish this we modified the existing database to be more widely accessible with an improved search interface and performance, better graphics and graphics management, integrated audio descriptions of the plants, and dynamic mapping of plants to enhance the learning experience. This online database is currently available and free to the public
To increase our program’s effectiveness, Cornell Garden-Based Learning ramps up educator enrichment opportunities
The European honey bee, an important pollinator of New York’s most lucrative vegetable crops, continues to suffer population declines due to Colony Collapse Disorder (CCD) as well as other biotic and abiotic factors. Consequently, fewer honey bee hives are available, causing hive rental fees to increase dramatically and forcing growers to either spend more on renting hives or gamble by not renting hives and hope wild bees will pollinate their crops.
