Sheep milk production has gained significant attention in the agricultural sector, particularly due to its high nutritional value and the growing demand for differentiated products. With a high content of dry matter, fat, total proteins, and casein, sheep milk is an excellent raw material for cheese production. China is the largest producer of sheep milk. In this context, sheep breeds play a crucial role, as each one has unique characteristics that influence both the quantity and quality of the milk produced. In this article, we will explore the five largest dairy-producing sheep breeds, highlighting their characteristics and origins.

The East Friesian is widely regarded as the most productive dairy sheep breed in the world, making it the best-known among dairy breeds. They are native to the northeast of Germany, highly specialized, and do not adapt well to extensive grazing conditions and large flock sizes.
One of their unique characteristics is their "rat tail" which is free of wool. East Friesians are known for their docile temperament and exceptional milk production. However, they are also very prone to diseases, particularly parasitic infections, requiring careful management and feeding practices.
So, when looking at this breed, keep in mind that their calm nature and high milk production come with the need for extra care and preventive health measures. Globally, New Zealand and Australia have the largest populations of East Friesian dairy sheep. These sheep have a lactation period of about 230 days and produce between 500 and 700 kg of milk per lactation.
The Lacaune breed is one of the top milk-producing sheep, with a long history of being selectively bred to improve both the quantity and quality of their milk. Thanks to a well-established genetic selection program, their milk yields have continued to improve year after year.
Compared to East Friesians, Lacaune sheep produce milk with a higher concentration of total solids (like fats and proteins), although the overall volume of milk is slightly lower. For this reason, farmers in the U.S. often crossbreed Lacaune sheep with East Friesians to create new breeds that can produce higher-quality milk.
Originally from the mountainous regions of France, the Lacaune breed is best known for its role in producing Roquefort cheese. Over time, the breed has been refined through a rigorous selection program in France, where they are primarily fed forage. Today, Lacaune sheep rank among the world's top milk producers, with an average yield of 400 to 500 kg of milk per lactation.
The exact origins of the Awassi sheep are unclear, but it's believed that they evolved in the region between the Tigris and Euphrates rivers, in present-day Iraq and Syria. The name "Awassi" comes from an ancient Arab tribe called El-Awas, which once lived near the Euphrates River in northern Syria.
Awassi sheep are the most widespread non-European dairy breed and are especially common in Southwest Asia. They are easily recognizable by their white body, brown head and legs, and distinctive "fat tail."
One of the most impressive traits of the Awassi breed is their ability to adapt to a wide range of climates and farming systems, from harsh steppe regions to intensive operations. Their performance varies depending on the environment, but they are generally hardy animals with a lactation period of about 214 days, producing around 500 kg of milk per cycle. Peak production typically occurs during the third week of lactation.
The Assaf breed was developed in Israel in the 1950s as part of a breeding program that aimed to improve milk production and lambing rates. The breed is the result of crossbreeding Israeli Awassi sheep with German East Friesians.
Through careful experimentation, breeders found that a 3/8 East Friesian and 5/8 Awassi cross produced sheep with the best balance of vitality, milk production, and reproductive performance.
Assaf sheep are known for their high fertility rates and are valued for both meat and milk production. They typically produce 300 to 400 kg of milk per lactation period, which lasts between 170 and 200 days.
These sheep are easily recognizable by their white bodies, with some individuals having brown legs and fat tails. The popularity of the Assaf breed continues to grow, and they have spread from their native region to other Mediterranean countries like Portugal and Spain. Assaf sheep have also been exported to countries such as Chile, Peru, and the United States.
The Sarda sheep is a breed native to the Mediterranean island of Sardinia and is one of Italy's most famous dairy breeds. These sheep are now raised throughout Italy and other Mediterranean countries, including Tunisia.
Sarda sheep are medium-sized, with white fleece. Males may have horns, but females are typically hornless. One of the breed's greatest strengths is its ability to thrive in extensive grazing systems, particularly in areas with sparse or mountainous pastures.
In Italy, most sheep milk is used to produce pecorino sardo cheese, which is popular throughout Europe. Sardinia is a major supplier of sheep milk in southern Europe, with over three million Sarda sheep on the island.
On average, Sarda sheep produce about 376 kg of milk per lactation.
Dairy sheep play a vital role in producing high-quality milk and have become increasingly popular among farmers worldwide. Each of the breeds discussed offers unique traits that can benefit different farming systems. Some breeds excel in productivity, while others are more adaptable to specific environments. By carefully selecting the right breed for their needs, farmers can be more efficient and contribute to the sustainable growth of the dairy sheep industry.
