Answer: The female
Hippopotamus gives the milk of blue color. Blue milk, also known as Bantha milk, was a rich blue-colored milk produced by female banthas.
The milk of the Indian rhinoceros was ivory white and aromatic. The appearance of 19-mo lactation milk in the African black rhinoceros was reported to be white and watery.
Actually, chocolate milk can come from any kind of dairy cow. Brown cows make the same kind of milk as black and white Holstein cows and reddish Devon cows.
Besides, giraffe milk has higher vitamin A and B12 content than cow's milk, but the content of riboflavin, thiamine, and vitamin B6 is similar. Therefore, from a nutritional point of view, although giraffe milk is rich in fat content, it is very healthy.
Pig milk is not considered suitable for commercial production for a number of reasons. Pigs are considered difficult to milk. The sow herself is reluctant to be milked, may be uncooperative or become spooked by human presence, and lactating pigs may be quite aggressive.
Cow milk is light yellow in color due to presence of carotene.
Guernseys are known as The Royal Breed thanks to their golden milk. A high amount of beta carotene – a source of vitamin A – gives the milk its rich color. Guernsey cows are from Britain, but are believed to have originated from two French breeds.
Hooded seals (Cystophora cristata)
Hooded seal mothers produce the fattiest known milk. Human breastmilk has about three to five percent fat in it. But with more than 60 percent fat, hooded seal milk would rival some of the richest Häagen-Dazs ice creams out there.
The platypus (Ornithorhynchus anatinus) has a puzzling array of features. Not only does it have that iconic duck bill, it lays eggs like a bird or reptile but feeds milk to its young like a mammal.
Lipid layers in the milk samples were variable, but primarily liquid (~80%) and clear in color; conversely, the opaque cream layer made up only ~20% of total milk fat quantified (Table 3).
Bright red, pink, coffee/chocolate brown, black or olive-green coloured breastmilk may mean there is some blood. The most common cause of blood in breastmilk is a cracked nipple.
Ahch-To's thala-sirens are docile marine mammals that like to sun themselves on rocks fringing the coasts of the planet's islands. Sea sows produce a nutritious green milk, which is harvested by the native Lanai and adventurous visitors.
Skim Milk = purple
Skim milk, or non-fat milk, has a purple cap indicating that it contains little to no fat. Not all grocery stores and brands follow this coloring system—so make sure to double-check the wording on the label before you throw the blue-capped milk in your cart.
Zebra milk is nearly 90% water, and the milk lactose concentration is similar to that of milk from primates (around 7%) [2].
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).
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.
Yak milk tastes sweet and has a fragrant, sweetish smell. Yak milk has between 15 and 18 percent solid content, 5.5 to 9 percent fat and 4 to 5.9 percent protein. It therefore has higher solid, fat and protein contents than cow and goat milk, and resembles buffalo milk.
Pig milk is milky white in color, has no special taste or smell, and is similar to cow's milk and goat's milk. The team's preliminary research found that pig milk has high nutritional value, and its nutrition includes energy, fat, protein, lactose, calcium, sodium, etc.
Some of the nutrients that are found in milk are coloured. Riboflavin or vitamin B2 which is an important enzyme cofactor has a greenish yellow hue.
Milk is naturally a white substance due to the make-up of water and other components including fat and protein that mix together to form tiny particles which reflect light.
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.
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.
The adult male counterpart of a cow is called a bull. They can't produce milk, but you can still find them on a dairy farm.
