World milk production is almost entirely derived from cattle, buffaloes, goats, sheep and camels. Other less common milk animals are yaks, horses, reindeers and donkeys. The presence and importance of each species varies significantly among regions and countries.
Aside from cattle, many kinds of livestock provide milk used by humans for dairy products. These animals include water buffalo, goat, sheep, camel, donkey, horse, reindeer and yak. The first four respectively produced about 11%, 2%, 1.4% and 0.2% of all milk worldwide in 2011.
Reindeer milk is among the richest and most nutritious of milks, at 22% butterfat and 10% protein; however a reindeer can be milked only for about 1.5 cups per day.
Narrator: Reindeer milk is very rare, and only a few places in Scandinavia actually milk reindeer. Reindeer milk has a shocking 20% fat content, compared to the average 3.5% for cows, but that fat content gives the milk a very rich and creamy taste. Reindeer can be milked for only about 1 1/2 cups per day.
Zebra milk is nearly 90% water, and the milk lactose concentration is similar to that of milk from primates (around 7%) [2].
Meanwhile, giraffe milk is much higher in fat than cow's milk – 12.5 percent compared to 3.5 percent. All that fat might sound like a turnoff, but recent research has shown that higher levels of dairy fat can also lead to a lower risk of diabetes.
Therefore, from a nutritional point of view, although giraffe milk is rich in fat content, it is very healthy. As you can imagine, the health data for Giraffe milk varies because animals have difficulty milking; in fact, few people consume regular giraffe milk.
Mare milk is sometimes chosen over cow milk for its purported health benefits. A niche market considers it a remedy for skin or digestive problems. Peer-reviewed papers suggest it can reduce atopic dermatitis or eczema. It is used to make cosmetics and can form cheese with camel rennet, but not bovine.
The camel is the most important provider of milk. Thirty-seven percent of all milk comes from the camel; 30 percent from sheep; 23 percent from the Yak and only 10 percent from cows. Little is known about the milk production of these members of the camel family.
Sows (female pigs) are difficult to milk. They are grumpy and don't like to be touched, plus their teats are much smaller than a cow's, so it's harder to get milk from them. They also produce less milk than a cow. For all these reasons, there has never been a culture of milking pigs.
Pig milk is milk from pigs, and is typically consumed by piglets. It is similar in composition to cow's milk, though higher in fat and more watery. Pig milk is seldom obtained for human uses and is not considered to be a viable agricultural product.
Hippopotamus gives the milk of blue color. Blue milk, also known as Bantha milk, was a rich blue-colored milk produced by female banthas.
Female dogs spontaneously produce milk when they have given birth to puppies. This is a normal part of biological parenthood for any female mammal. Female dogs may also produce milk when experiencing a false pregnancy or when another creature attempts to nurse from her.
Answer: The female black rhinoceros or Diceros bicornis give black milk. Explanation: Black milk is the slimmest milk containing very little amount of fat (0.2%) is produced by Black rhinoceros.
Tammar Wallabies (Macropus eugenii)
Tammar wallabies, found in southern and western Australia, produce sugar-rich milk for their joeys. Their milk contains about 14 percent sugar, double the amount present in human milk and one of the highest levels among mammals.
Dog milk is the breastmilk that has been extracted and harvested from a female dog. This milk is essential in the growth of a newborn puppy. It definitely should not be used for human baby consumption. One, that's disgusting, two it has inadequate nutrients for a human baby.
Because of its high calcium content, sheep milk is also very good for the prevention of osteoporosis and for those people already suffering from it. Sheep milk is the most nutritious milk on sale in the world today.
Similarly, the red kangaroo can produce two different kinds of milk, depending on the age of the young (Griffiths, McIntosh & Leckie, 1972). One gland can produce a fluid rich in protein for a neonate and the other “mature” milk for a young at foot (Griffiths, McIntosh & Leckie, 1972).
Donkey and horse milk have the lowest fat content, while the milk of seals contains more than 50% fat. Whale's milk, not used for human consumption, is one of the highest-fat milks.
As for sheep's milk, almost no one in the United States or anywhere else drinks it straight. It has twice the fat of cow's milk and human milk, making it too rich to be very appealing as a beverage.
Penguins, being birds, don't have “milk” like mammals do. Instead, they produce this secretion which is sometimes called crop milk. This is a fatty, high protein food that is developed in their crop (a pouch in their throat) and given to chicks during key developmental stages.
Simple Summary. The composition of elephant milk differs from all other mammals, as well as between Asian and African elephants. The changes of this milk composition during lactation is also unique. Apart from the major sugar being lactose, sugars also occur as longer chains.
Unique aspects of elephant milk have been described, including small sized and highly saturated lipid globules [21,22], and the presence of elevated concentrations of lactose-derived oligosaccharides [23], as well as high levels of glucosamine [24].
