Yesterday, in our continued quest to consider the future of a family dairy farm, we visited what must be the largest such farm in central Costa Rica. At 7,545 feet above sea level overlooking the valley from the northern slope, it may also be the highest.
It has eight times the land and double the cows compared to where we are based, 10 miles north and about 1,000 feet lower in altitude. That farm also has dairy goats. More on other implications of the visit later. Here, a quick note on feed. We had noticed on the dairy where we live that pineapple is part of the diet of the cows.
The dairy manager had explained that this is an important part of the nutritional mix. Despite our surprise we had not asked more about it. Yesterday we did, and the answer was another surprise. Milk production rises 10% or more with the pineapple added to the feed. The animals are healthier because of the fiber content of the fruit, compared to cows eating grains such as corn or soy. Plus, the methane bi-product is significantly decreased. Food produced in a dairy making this dietary change represents one small step toward reducing greenhouse gas emissions.
In the type of coincidence I never expect, but always enjoy, this article was near the top of my news feed today. Thanks to Judith Lewis Mernit and colleagues at the Yale School of Forestry & Environmental Studies for take my yesterday’s lesson and adding some important detail:
How Eating Seaweed Can Help Cows to Belch Less Methane
Emissions from the nearly 1.5 billion cattle on earth are a major source of methane, a powerful greenhouse gas. Now, researchers in California and elsewhere are experimenting with seaweed as a dietary additive for cows that can dramatically cut their methane production.

The spring morning temperature in landlocked northern California warns of an incipient scorcher, but the small herd of piebald dairy cows that live here are too curious to care. Upon the approach of an unfamiliar human, they canter out of their barn into the already punishing sun, nosing each other aside to angle their heads over the fence. Some are black-and-white, others brown; all sport a pair of numbered yellow ear tags. Some are more assertive than others. One manages to stretch her long neck out far enough to lick the entire length of my forearm.

“That’s Ginger,” explains their keeper, 27-year-old Breanna Roque. A graduate student in animal science at the University of California, Davis, Roque monitors everything from the animals’ food rations to the somatic cells in their milk — indicators of inflammation or stress. “The interns named her. She’s our superstar.” Continue reading

At Xandari we offer a garden and farm tour that consists of showing guests through our botanical garden, Mandala garden, and orchid house and educating them on the properties of each of the plants. When I was asked to translate the tour for our head gardener Jose Luis I immediately accepted. However, after agreeing to be the translator it dawned on me that my rudimentary knowledge about plants (species, genus, and all that scientific terminology amounts to high school level biology) could be a limitation to the learning experience of the guests. Adding to my worry, the guests taking the tour are well versed in plant identification and were hoping to learn more about the tropical plants we have. To prepare myself, I skimmed the plant identification binder we have, decided to take it with me on the tour, and hoped for the best.
