In article it is told about how on zootechnical signs to select the hens possessing a high yaytsenoskost.
Despite danger of outbreak of bird flu and difficulty with acquisition of forages because of their constant rise in price, many inhabitants of villages continue to hold hens. After all this and fresh dietary egg and meat pensioners can be indulged as to buy it on scanty pension it is almost impossible.
Autumn – time of completion of selection of birds. Very valeno it is well to select nesushhuyusya chicken. After all and that that bears many eggs, and that which at all doesn’t bear them or gives it is not enough, consume identical quantity of forages. That wasn’t perevoda harchy, it is necessary to select hens with a high yaytsenoskost.
Zootechnical practice developed much enough reliable signs, svideyotelstvuyushchy hens about a yaytsenoskost. If you get a bird in the autumn, turn a vniyomaniye on her plumage. It is known that at this time bad layers stop a yayyotsekladka, and good it continue. Good layers fade closer by autumn, ployokhy – since the beginning of summer. Bad layers reduce a yaytsekladka from June to August and in September finish a molt.
At such hens plumage pure, brilliant, and feet and beak the bright yellow. And good nesushki, more long continuing to postpone egg, by then yet perelinyali and vyglyadyat is worse. Plumage at them opaque, slightly polluted, feet and a beak pale, are almost deprived of coloring.
At the strengthened yaytsekladka the painting yellow pigment – ksantofil, saved up in an oryoganizm, gradually passes to eggs. As a result separate parts of a body of hens obescvechivayutsya. This process takes place in a certain sequence. In the beginning grows white kozha round a cloacal opening (in 1-2 weeks after the yaytsekladka beginning), then round eyes, on ear lobes and a beak – in 1-1,5 months and in the end (not less than 4 months) – standing. It is possible to determine by this sign and duration yajcekladki. On a tribe it is necessary to select young women with bright orange feet and a beak and a yellowish young feather.
Efficiency of a bird can be estimated on number of the replaced moss feathers – the less bird lost them by October, the higher and a yaytsenoskost.
As quite good sign the crest, ear rings serve also. At rushing hens they royozovy or red, bulked up, warm to the touch, and at not rushing – cold, dryabyoly, dryish, pale.
Young women with a big crest start to rush earlier and weigh more, than those, at kotoyory a small crest. Selection of hens on this sign can be carried out, since three / months. And from six-month-old hens of breed leggorn on a tribe it is better to leave those. at koyotory the length of a comb exceeds 7 mm.
It is important to pay attention and to such sign. A cloacal opening at rushing hens bulked up, damp, the increased size, lonny bones semi-opened, plastic, flexible and straightened, at not rushing – rough, are bent inside, and a foul place narrowed, dry and wrinkled. If at a proshchupyvaniye of a bird between the ends of lonny bones not less than three fingers are located (at obshchepolzovatelny breeds not less than four), this bird rushes, if less than two – the yaytsekladka is stopped).
