Dairy Goat Breeds
Who’s Responsible For All That Great Cheese?
Goats are one of the oldest domesticated species. Goats have been used for their milk, meat, hair, and skins over much of the world. In the twentieth century they also gained in popularity as pets. Unlike the ornery, tin can- and laundry-eating billy goats of our cartoon youth, goats are delightful creatures. They make wonderful companions and pets. Goats are extremely curious and intelligent. They are easily trained to pull carts and walk on leads.
Goats produce approximately 2% of the world's total annual milk supply. Some goats are bred specifically for milk. If the strong-smelling buck is not separated from the does, his scent can affect the milk.
Doe milk naturally has small, well-emulsified fat globules, which means the cream remains suspended in the milk, instead of rising to the top, as in raw cow milk; therefore, it does not need to be homogenized. Indeed, if the milk is going to be used to make cheese it is recommended that it is not homogenized as this changes the structure of the milk impacting the culture's ability to coagulate the milk and the final quality and yield of cheese.
Dairy goats in their prime, which is generally around the third or fourth lactation cycle, average 6 to 8 pounds (2.7 to 3.6 kg) of milk production daily (roughly 3 to 4 US quarts (2.7 to 3.6 liters)) during a ten-month lactation, producing more just after freshening and gradually dropping in production toward the end of their lactation. The milk generally averages 3.5 percent butterfat. A doe may be expected to reach her heaviest production during her third or fourth lactation.
Doe milk is commonly processed into cheese, butter, ice cream, yoghurt, cajeta and other products. Goat cheese is known as chèvre in France, after the French word for "goat". Some varieties include crottin, Rocamadour and Montrachet. Goat butter is white because goats produce milk with the yellow beta-carotene converted to a colorless form of vitamin A.
Introducing The Goats
Dairy goats can live comfortably into old age while producing a large amount of delicious milk. Dairies breed species for good milk flavor (other goats are bred for meat flavor).
An average mature dairy goat female weighs 150 pounds, and produces a gallon of milk per day. Top producers can average two gallons (compare that to a cow, which gives ten gallons of milk a day). You can purchase a mature doe in the range of $350 to $600, depending on breed and quality of production.
While there are hundreds of goat breeds worldwide, five major breeds of dairy goats are used to make cheese in the United States: Alpine, LaMancha, Nubian, Saanen and Toggenburg. Most dairies use several and vary them between the high milk producers and the high butterfat producers. The high butterfat breeds like LaMancha and Nubian make richer cheese, but don’t produce enough milk to sustain a profitable operation: they might yield only one gallon of milk a day. Their milk is blended with that of more prolific breeds, like the Alpine, which might produce up to two gallons a day, to enable a larger production
