Blood in a chicken egg: causes of appearance in the yolk and protein, what to do, is it possible to eat

Anonim

Cultivation of chickens on a home farm for eggs and meat is the oldest branch of agriculture. It is difficult to imagine a village courtyard without multi-colored laying hens wandering around the yard and pans with hot scrambled eggs from the freshest eggs. Often, the hostess discovers blood clots in a chicken egg. There is no desire to eat such a product. The poultry breeder needs to understand the reason for the demolition of the “bloody” marriage by the bird and eliminate it.

Why is there blood in chicken eggs

The egg in the body of the chicken matures 24-28 hours. First, the yolk is formed, then the formed protein surrounds it, and the shell is formed last. At any of these stages, a blood clot can form. The reason for this phenomenon may be:

  • abdominal bruises (the chicken unsuccessfully flew off the perch and hit its stomach, causing a microtrauma with blood to form in the oviduct);
  • too many roosters hurting hens;
  • wrong diet with an imbalance in trace elements;
  • inflammation of the oviduct and ovaries;
  • presence of internal parasites;
  • young laying eggs are too large.

Depending on the location of blood clots, you can determine the exact cause of their appearance.

In protein

The most likely cause of blood clots in the protein is the wrong diet of the bird and the presence of worms in the laying hen.

Lack of mineral nutrition (shell, chalk, crushed eggshell), lack of greens in the diet, leads to improper egg formation. The chicken not only begins to “pour” them (lay without the shell), but red dots and balls may appear in the protein.

Parasites in the body of a chicken injure its internal organs, causing microbleeding.

Part of the blood enters the egg as it forms. With a strong infection of the bird, even the helminths themselves can get into the egg white.

On the shell

Blood on the shell appears at the time of egg laying chicken. Too large an egg injures the oviduct or cloaca, traces of blood remain on the shell. Often this occurs in young hens of egg breeds, which immediately begin to lay large eggs.

Sometimes the egg gets stuck in the oviduct, the young hen cannot lay it. A quick help to a bird is to introduce a small amount of sunflower oil from a douche into the cloaca. Lubrication makes the shell slippery and helps the egg to slip through.

In yolk

Blood clots or subtle spots appear in the early stages of yolk formation. Often this is due to an excess of protein supplements (meat, fish, meat and bone meal, cake) in the diet.

Excess protein in chicken feed disrupts mineral metabolism, reduces the absorption of calcium and phosphorus.

Lack of vitamins D, E, A leads to inadequate functioning of the ovaries, the integrity of the follicle shell is violated. This can also cause blood in the yolk.

Due to diseases of the oviduct and ovaries (inflammation, the presence of the smallest pathogenic microorganisms), at an early stage of egg formation, blood enters the yolk, and then it mixes with protein. Such an egg has a pasty reddish-yellow substance inside.

Ways to solve the problem

Having determined the cause of the presence of blood in the yolk or protein, it should be eliminated:

  • bring the livestock diet in line with the norm;
  • start feeding vitamins and provide laying hens with mineral supplements;
  • set perches at a safe height and remove extra roosters from the flock;
  • treat the bird for worms.

Diseases of the oviduct (salpingitis, yolk peritonitis) are difficult to treat, especially if they are in advanced form. Such a bird is rejected. A valuable breeding hen is placed in a separate box and treated by douching the oviduct with antiseptic preparations.

Helpful tips and prevention

In order to prevent the appearance of "blood" eggs in domestic laying hens, it is necessary to follow the rules for keeping and feeding birds:

  1. Exclude bird injury. Perches should be placed at a height of 60-90 cm from the floor.If they need to be installed higher, the crossbars are nailed in the form of a "slide" or "ladder" so that the chicken can jump from one perch to another, going down. The distance between the crossbars should be no more than 50 cm. The number of roosters in egg breeds should not exceed 1 individual per 10 hens. In meat varieties, 2 roosters per ten layers are allowed.
  2. Regularly deworm chickens. Planned deworming is carried out twice a year - in spring and autumn. If laying hens are free-range, parasites are poisoned more often - once a quarter. The danger of infection is present in chickens fed fresh grass harvested from damp meadows.
  3. Give your livestock a balanced diet. The general feed rate per laying hen is 150 grams. Overfeeding is just as bad for a bird as underfeeding. It is optimal to feed laying hens with complete mixed feed, in which all the elements necessary for the bird are present in a balanced form.

At home, chickens are fed grain mixture, with additives. An approximate daily diet for a laying hen looks like this:

  • crushed grain mixture (corn, wheat, barley) 60 grams;
  • wheat bran 20 grams;
  • sunflower cake 10 grams;
  • fish meal 5 grams;
  • feed yeast 3 grams;
  • fresh greens (herbal flour), vegetables 40-50 grams;
  • table s alt 1.5 grams.

Premix (Zdravur Laying hen, Ryabushka) is added to the grain mixture for laying hens for enrichment with microelements. Chalk, shell rock and shells are placed in a separate trough so that the bird can freely peck at them at any time.

Can I eat "bloody" eggs?

If only the shell is stained with blood, such a product can be safely eaten.

It is enough to wash the shell with soap.

Eggs with small blood spots and clots can be eaten after heat treatment - well-done or hard-boiled. Blood particles are removed from the mass.
