Why are chickens and roosters painted differently?

Not only birds, but animals also have malespainted more brightly than females. What is the reason? Yes, just males need to seduce a female. And females, as a rule, incubate and raise offspring. For these purposes, they need a less bright color. This is a kind of protection from predators. But people are the opposite.

But why are chickens and roosters painted differently? Chickens have a pronounced anatomical structure - sexual demorphism. From female

individuals of chickens are distinguished by their colorfulplumage. Plumage stands out most on the neck and on the lush long tail. Roosters on the lower legs appear bone growths - spurs. Both the chicken and the rooster have a clearly visible comb and beard on the head. The comb and the beard are organs of thermoregulation. They redirect blood flow to the skin. Usually, the comb of a rooster is larger than that of a chicken.

Теперь мы выяснили, почему куры и петухи окрашены differently. But maybe their conditions are somehow affected by their conditions? Let's look at the content of laying hens at home.

In houses, chickens are usually grown on the floor, using litter. Sometimes poultry farmers keep poultry stock in cages or on mesh floors.

Floor content

Эта система предусматривает помещение кур на deep litter from moisture-intensive and friable materials with low thermal conductivity. With outdoor cultivation, the bird can move more, and this has a positive effect on its health. Before planting a party of birds, the litter is laid with a thick layer of about 20 cm. It is removed only after the birds are kept.

Content on mesh floors

If one square meter in the floorgrowing up to five heads of poultry, while growing on mesh floors - up to twelve heads. Here the capacity of the house is increased two and a half times.

Chickens in cages

This method is more progressive, compared with the placement of birds on the net floor. So contains a bird on large

poultry farms producing eggs. In home apartments, chickens in the cages almost no one contains.

Но каким образом происходит кормление кур-несушек?They feed twice a day with full-fledged dry food. The level of filling the feed depends on the filling level of the feeders. It should not exceed two thirds of the feeder.

Feeding dry feed providesdaily rate: about 120 g of feed per one hen. For the year, one chicken consumes about 44 kg of feed. If juicy and green fodder is included in the ration of the hens, the volume of the daily norm increases to 170 g and more.

Succulent and green feeds have a beneficial effect.the state of the body of rushing chickens, their productivity and vitality. We tried to figure out why the chickens and roosters are colored differently. We see that neither the content nor the feeding have any effect on the color of the plumage.

Chickens are probably the most common birds on planet Earth. By some estimates, their number now exceeds 13 billion! Humanity receives from chickens about 600 billion eggs per year.

Of course, everyone is interested to know why chickens and roosters are painted differently. But agree, this question does not interest anyone when delicious scrambled eggs are served at the table for dinner.
