question 1 of 4

The scientific name of the domestic fowl is...

Gallus gallus domesticus

Avis ponis huevus

Collect

Clocotis plumifera

QUESTION 2 OF 4

The oldest archaeological remains of chicken domestication are from 8,000 B.C.E. (before the common era) in China, 2,000 B.C.E. in the Indus Valley and 1,350 C.E. (common era) in Chile. What can this mean?

That Chinese hens are older.

Collect

That chicken is a typical dish in Central Asia.

That, despite what many people think, chickens did not arrive in South America as a result of the European invasion, but -probably- through Polynesia.

QUESTION 3 OF 4

Healthy, well-fed adult hens that receive at least 12 hours of light per day can lay 1 egg every 24 hours. But not all of their eggs are fertilized, so how can you tell?

Fertilized eggs are white and unfertilized eggs are clay-colored.

A small white dot can be seen on the yolk of a fertilized egg.

Collect

Fertilized eggs have two yolks and cannot be eaten.

QUESTION 4 OF 4

A chick takes 21 days to hatch, from the time the egg is laid. Traditionally, broody (quieter) hens were used to hatch the eggs. Alternatively, farm incubators are used to ensure that the majority of fertilized eggs produce chicks. Incubators were invented...

In the United States, in 1844, they operated with hot water and could hold more than 300 eggs.

Collect

In Ancient Egypt, c. 3,000 B.C.E., caves and clay ovens were used as incubators.

A steam engine in the shape of a broody hen that hatched 1,000 eggs was presented at the Paris Universal Exposition (1889).

Well done! The hens are calm and happy

Cluck, Cluck, Cluck!

QUESTION 1 OF 4

The stomach of cows is composed of four pouches: the rumen, the reticulum, the omasum and the abomasum, each of which has a specific purpose. What are their functions?

In the rumen, food accumulates almost without chewing, the reticulum pushes the food back into the mouth for rumination, the omasum filters water and gives bacteria time to break down the food, the abomasum produces acids, buffers and enzymes to finish breaking down the food.

Milk

Dry grass accumulates in the rumen, green leaves in the reticulum; the omasum and abomasum shake the food very hard to break it down and pass the nutrients to the intestine.

QUESTION 2 OF 4

Since the beginning of their domestication of cows, some 10,000 years ago, people have selected the best specimens (which give more milk, or more meat, as desired), to breed. How is this process done today?

Milk

The most beautiful cow that produces the most milk is chosen. In a laboratory, this cow is cloned over and over again. That's why they all look so much alike.

The best-breeding females are selected and given hormones to produce many eggs. These are artificially inseminated and the embryos are transferred to other cows that are calm and calve well, to give birth to calves.

QUESTION 3 OF 4

What is the daily menu of a dairy cow?

A couple of bananas and five alfalfa-flavored energy bars.

Milk

50 square meters of grass and 40 liters of water.

Between 25 and 50 kilograms of feed (silage and grass) and 172 liters of water.

QUESTION 4 OF 4

Dairy products are the main source of calcium in the Western diet. In addition, milk and its derivatives are high in vitamins B2 and B12, phosphorus, potassium, vitamin D and protein. However, there are people who cannot consume them due to...

Due to allergy to milk proteins or intolerance to lactose, the natural milk sugar.

Milk

Because it is not recommended to consume milk or its derivatives after breastfeeding.

Well done! Your cows are happy :)

question 1 of 4

Pigs were domesticated from wild boars about 9,000 years ago. How many varieties of pigs are raised in the world today?

Feed

QUESTION 2 OF 4

Some studies indicate that pigs raised in an unstimulating environment have poorer long-term memory, among other problems. Which of these environments do you think is the most suitable for a captive pig?

Feed

QUESTION 3 OF 4

The pig genome has 22,342 coding genes. Some of these genes contain a mutation that protects them against snake venom. What other animal has this protective gene?

Feed

QUESTION 4 OF 4

It is said that every part of the pig is valuable, “even the squeak”. What is a resource derived from the breeding pig that, properly processed and applied, contributes to the circular economy of the countryside?

Feed

Awesome! Now that's eating like a pig....

Oink, oink!

QUESTION 1 OF 4

If you were in charge of veterinary services on a sheep farm, what would you look at to evaluate their health?

The appearance of its eyes, teeth, tongue, coat and hooves. As well as their appetite, energy, noises and temperature.

Shear

If I raise my hand and get a 'high five', everything is OK.

QUESTION 2 OF 4

What are some of the advantages of natural wool over some synthetic fibers?

That you can knit patterned wool sweaters. The uglier, the better.

Shear

It is a renewable resource, is not derived from fossil fuels, is non-irritating and has applications in industry, in addition to textiles.

QUESTION 3 OF 4

Free-grazing sheep are a sustainable alternative to herbicides. Why?

Both are true. In fact, some universities are using sheep instead of lawn mowers.

Shear

Sheep graze without pulling weeds, thus not altering the biodiversity of the soil.

At the same time as they eat, sheep poop, thus returning organic matter to the soil and preventing soil degradation.

QUESTION 4 OF 4

There are many varieties of sheep. In the Valencian Community, the Guirra sheep was in danger of disappearing because there was no generational replacement among the shepherds. Could you recognize it?

It's this white one, who can make fallera bows and seems to love horchata.

Shear

It is this reddish one, which looks like it just came out of the gym and is reminiscent of socarrat paella.

Well done! Sheep are cool for the summer.

El origen del ganado vacuno: la domesticación de los uros

El ganado taurino (Bos taurus) y el cebú (Bos indicus) descienden del extinto buey salvaje o uro (Bos primigenius), que, durante el Pleistoceno y Holoceno, vivía en Eurasia y África. Según la evidencia arqueológica y los estudios de ADN realizados, el uro se empezó a domesticar en el Neolítico en el Levante mediterráneo, Mesopotamia y el Oriente Próximo.

Reflexiona:

  • ¿Cómo ha cambiado el tamaño del ganado a lo largo de su domesticación?
  • ¿Por qué crees que se han seleccionado especímenes más pequeños primero y más grandes después?
