Alfalfa-grass or red clover-grass: Effects on milk production, composition, nitrogen, and energy utilization 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.

Alternative forages for seasonal slumps 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.’

Breeding edible and ornamental strawberries for New England 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.

Disease threats and biofungicide efficacy in soilless substrates In greenhouse production, plants are not typically grown in soil but in soilless growth substrates. For decades, peat moss has been the primary substrate for container-grown ornamentals and for some vegetable crops. However, substrate suppliers have faced unprecedented demand, which has led to product shortages and an inability to fulfill orders. Substrate manufacturers have identified wood byproducts to be some of the most promising alternative sources of raw materials to use in substrate formulations. This research considers how wood substrate components affect the severity of soil-borne diseases in greenhouse horticultural crop production.

Effect of selisseo on selenium in milk and in blood for mid- and late-lactation holstein cows Selenium (Se) is an essential trace mineral that, if deficient in soil, will be deficient in diets fed to dairy cows. Adequate Se is important for animal health to support immune functions and efficiently fight oxidative stress and pathogens. Standard farm practice is to supplement Se in the diet either in mineral form (sodium selenite) or organic forms. This study compared the bio-efficacy of two organic Se sources in mid-lactating dairy cows based on the Se transfer into plasma and milk.

Effect of sodium butyrate, monensin, and butyric acid on Eimeria bovis sporozoites COLSA scientists Pete Erickson and Tom Foxall led research that found evidence that the compound sodium butyrate—a nutrient that people obtain by consuming beans, peas and other legumes, but that can also be added to animal feed—could be used as a coccidiosis preventative in cattle. Coccidiosis is an intestinal disease that affects livestock around the world.

Effects of incremental amounts of red seaweed on milk production, composition and methane emissions Enteric fermentation (fermentation taking place in the digestive system of animals) by ruminants is the largest source of methane emissions in the US (approximately 25% of total methane emissions). Recently, algae-based feeds have gained attention because they may be able to not only suppress methane emissions, but also to improve animal feed efficiency. Our objective was to evaluate how incremental increases of the seaweed Chondrus crispus affects milk and methane production in organic dairy cows.

Feeding nicotinic acid: Effects on pre-partum cow health, colostrum and calf performance Colostrum is essential for calf health from the increase in protein content (antibodies and growth factors). However, about 60% of the colostrum produced in the United States fails to meet quality standards. Since nicotinic acid increases blood flow and potentially rumen bacteria growth, adding this to the diet of dry cows could enhance the quality of colostrum for calves. This research examines that hypothesis.

Feeding sodium butyrate to post-weaned replacement heifers Raising replacement heifers is one of the largest expenses on the farm. Thus, it is important to closely manage young-stock with adequate nutrition to ensure those animals reach developmental maturity. Performance can be affected through diet manipulation, such as changing the volatile fatty acid proportions in the rumen. Scientists found that sodium butyrate is an adequate replacement for monensin in the diets of post-weaned heifers for both growth and reduction in coccidiosis. Sodium butyrate could potentially be fed from birth to first calving for increased nutrient use, growth and improved health.

Feeding wet brewers' grain to heifers It has been a common practice to feed wet brewers' grains to dairy cows, but no data were available indicating how to feed it to post-weaned heifers. Wet brewers' grains have a propensity to spoil. This research determined how preservation can be increased and whether there are positive or negative effects on performance as compared to heifers fed a conventional diet.

High tunnel eggplant varieties, pruning and postharvest storing Recently, parthenocarpic varieties of eggplant (varieties that fruit without pollination) have been developed specifically for protected cultivation. In places where eggplant is frequently grown in greenhouses, various pruning systems are used to enhance plant productivity and growth. In this study, researchers compared 10 varieties of elongated Italian eggplants to determine whether pruning to a 2- or 4-leader system would impact yields (when compared with no pruning) and the effects of postharvest storage on different varieties.

Identifying the highest-yielding varieties of brussels sprouts for New Hampshire Brussels sprout (Brassica oleracea L. var. gemmifera) is a popular fall crop in New England. However, rapid turnover in the commercial availability of Brussels sprout cultivars – coupled with dramatic differences in the performance and adaptability among cultivars – make it a challenging crop for growers outside of major production regions to select varieties that will consistently perform well. While a 2013–15 study of Brussels sprout varieties offered recommendations for New England producers, new varieties have since been released. This research focused on re-examining best-performing varieties for the northern New England region and updating best practice recommendations.
