Badly hens, eggs very small rush. In what the reason?
Eggs – one of the most perfect products of the nature which contains a high-quality protein, vitamins and the mineral substances necessary for the person. The quantity of an egg protein became a standard on which value of other proteins is measured.
Production of eggs everything increases every year. However both consumers, and producers become more exacting to their quality: eggs should be ecologically safe (a pure product), tasty, homogeneous, large, fresh and cheap.
Modern hens of egg cross-countries start to rush relatively early (4,5-5 months are elderly) that conducts to decrease in their live weight. At an early yaytsekladka ability to forage consumption at hens doesn’t manage to develop adequately. Therefore hybrid layers, without receiving the nutrients necessary for formation of egg, use own reserves. Such load of a young organism provokes slowed-down its development. Therefore by the beginning of a yaytsekladka of a bird should be well prepared.
The underfeeding in an initial phase of a yaytsekladka causes physical weakness in birds, and further affects plumage and development: frame becomes weak, the bird suffers from obesity, her stability to stresses goes down.
But it is considered the most significant the slowed-down gain of weight of egg. To receive eggs of the big size from young birds during the first yaytsekladka it is almost impossible. It is reached over time, namely at 15-21-week age of hens when the energetichnost of their diet raises. Irrespective of limited ability to consume a forage, hens in this case receive more energy owing to what the mass of egg increases.
The stern should contain 1-2 % of calcium; too large number of this substance limits its poyedayemost. When calcium level in a young growth diet (15-22-week age) is in optimum limits, its utilization at the end of the period of a yaytsekladka improves and the shell keeps the durability. During this period and level of serosoderzhashchy amino acids (methionine and cistina) in a diet of young growth should be higher (0,56-0,74 %), than in a diet of adult laying hens (0,55 %).
At early age (especially the 1-8th week) in a diet of hands there should be a raised maintenance of a lysine (0,98 %) which stimulates a gain of live weight of young growth. The lysine is necessary also for increase in weight of eggs. And as a whole high caloric content (290 kcal) kormosmesi during this period provides more uniform increase in live weight of birds.
At this time the special attention should be turned and on durability of frame at the birds which development depends on physical exercise. The reason of its weakness hens at the age of 16-18 weeks can have so-called a calcic shock, caused by transition to new forages. After all in a diet of young growth of calcium contains – 1,1-2,0 %, and in a diet of laying hens – 3,4-3,6 %.
The need for this element increases at birds one week prior to emergence of the first eggs. Except a muscular fabric, at birds bones, and a calcium and phosphorus ratio in bones other, than in a shell of eggs continue to develop. Therefore kormosmes for young growth of 15-22-week age should provide high durability of frame and a good physical condition of layers during the whole productive period.
Young growth feeding during this period should affect a plumage condition positively. If at layers good plumage, forage expenses as for maintenance of necessary temperature the organism doesn’t need additional energy decrease. It is possible to influence formation of a feather, raising level saliferous in a diet of hens of amino acids.
Except feeding, the important role is played by light modes by means of which it is possible to regulate puberty of birds, and such indirectly to influence increase in weight of eggs. The programs of lighting are developed for hens of different cross-countries, but they should be corrected in process of changes which are undergone over time by a bird of this or that cross-country.
Out-of-date programs can lead to delay of a yaytsekladka or excessive increase of weight of eggs at the end of the productive period.
The various light modes regulating time of a yaytsekladka, cause also intensity of a water consumption during the day. It is known that the body of adult birds contains about 65 % of water, as much in egg, at young growth – 75 %, and at a fat bird – only 50 %. Loss of 10 % of water leads to serious violations in an organism of a bird, and loss of 25 % – to her death. Rushing chicken consumes 190-250 ml of water, instead of rushing – 160-190 mm. The most useful and pleasant water for hens with temperature 10-150C. At a bird the water consumption sharply increases right after a sneseniye of egg and before the termination of light day. Therefore interruptions in providing with water in these hours are inadmissible. At a lack of water not only the yaytsenoskost decreases, but also eggs happen small.
The need of hens for drinking water depends on age, level of efficiency, environment conditions, and also from the content of solid and mineral salts in a stern, qualities of water and other factors.
So that to receive it is a lot of large eggs, it is necessary to contain and feed hens according to biological and physiological features of their organism.
