Jersey giant chickens
The recently emerged breed of chickens, the Jersey giant is considered one of the record holders in terms of mass, as it provides a sufficient yield of meat products.
About Jersey Giants
The egg and meat breed of chickens, the Jersey giant, appeared on American poultry farms around the 1920s. It was bred in the process of crossed Bramsky hens of the breed Orlington and representatives of the Langshans.
The Jersian giant chickens owe their fame to very heavy weight. A laying hen can gain a mass of about 4 kg, for males a good average weight is up to 6-7 kg.
The Jersey breed of giants was registered in 1922 as an independent type of poultry.
Initially, the birds had only black plumage. The results obtained in America were fixed at the genetic level in England, where representatives of the breed received various shades, not only black, but also red (tomato colors), white and even blue colors appeared. Subsequently, the egg-meat breed was spread throughout the European territory, continuing to participate in a variety of experimental crosses. Russian poultry farming got acquainted with a rare breed of hens Dzhersky giant a little later.
Description of the breed of chickens The Jersey giant begins with an indication of their large size and muscular physique. Despite the powerful constitution, the representatives of the giants are graceful, moving on long, widely set four-fingered paws. Their body is quite long, resembling a broiler, with a wide dorsal section, developed shoulders, a well-built belly and a deep chest.
Among the plumage color, 3 main colors are distinguished, which are most often found in the breed:
- the traditional black Jersey giant has a blue ebb of a feather, the color of the beak is similarly black, the metatarsus with a yellow tint,
- white with yellow metatarsus and beak pierced by dark veins,
- blue with an ash tint, the dark beak of which is marked with a yellow spot at the very tip, metatarsus are close to black with a yellow bottom.
The tail of the Jersey chickens is formed by numerous sickle-shaped feathers, densely planted, located at a 45-degree angle relative to the dorsal region. All photos of the Jersey giant breed show a smooth shiny chicken tail as a kind of bird decoration.
The description in the photo and video about the Jersey giants is noteworthy in that the layers are not much different from cocks, only a little squat and shorter. However, hens can be distinguished by a more magnificent tail, planted a little lower than that of roosters. Jersian giant roosters can also be recognized by their larger head size.
The main feathers of birds of the described breed are densely set and smooth. The tail unit is wide and long, adjoins from the sides to the body rather tightly. Jersian giant leaf-shaped bird scallops, divided into 6 teeth, are set upright, as well as scarlet-colored lobes, like fresh tomato. The eye iris is usually dark brown, close to black. The eyes are round in shape, rather large in size, convex.
Jersey colors affect the prices at which they can be bought.
The Jersey giant has a high rate of weight gain, acting as a supplier of large quantities of chicken. By the age of 1 year, males can gain weight up to 5 kg. The chicken by the time the egg laying process begins weighs about 3.5-3.7 kg.
Jersey chick is notable for the intensity of gaining live weight in the initial 5 months, gradually reducing growth rates. On average, the Jersey giant chickens continue to grow until they reach the age of 1.5 years.
After reaching the age of five months, keeping chickens becomes less profitable. The price of products no longer justifies the investment, as a lot of feed is eaten, and the growth rate is significantly reduced.
Oviposition of chickens begins at the age of seven months, providing for a period of up to 180 pieces. Jersey eggs with a strong brown shell. The weight of each egg from a layer of Jersey breed varies between 55-60 g. The selling prices for hatching eggs vary within 100 rubles per piece.
Creating conditions for content
Among the subtleties of keeping chickens, the Jersey giant stands out the need for weight gain in the first year of life, especially the first 5 months.
Keeping Jerseys requires a lot of space for their walking, especially in the warmer months, to provide birds with access to grass, pebbles and insects. However, even in conditions of enclosure, Jerseys are able to gain the necessary weight and provide the expected productivity from them, subject to the rules of landing: no more than 2 birds per 1 sq. Km. m square. The advantage of arranging walking pastures is that they do not require high fences, since the Jersians practically do not fly due to their heavy weight.
In winter, the room where the chickens are kept should warm up to 10-12 ° C, although reviews by poultry farmers note that lowering the temperature to -5 ° C does not significantly affect egg production. Among the prerequisites - regular ventilation to provide fresh air. For the outflow of ammonia and hydrogen sulfide compounds released during the life of chickens, some poultry farmers mount a gas outlet, cutting it from the bottom of the house wall. In the house, the floor is lined with straw or sawdust.
Jersey chickens are fed from 2 to 3 times a day, preferring wet mixes made from animal feed. The best option for them will be cereals. The prenatal feeding regimen will improve the quality of oviposition and gain weight. In the daily diet of the meat giant, it is recommended to include up to 40% of corn on the cob, up to 40% of millet and about 10% of oilcake, shell rock and vitamin supplements.
For chickens, the conditions of detention are somewhat different. Young animals in the diet should have sufficient calcium, vitamins A, D and E. Newborn chickens are placed in a warm place where the temperature does not drop below 28-26 ° C, there are no drafts and there is no excess moisture.
Often, poultry farmers use dry compound feeds or wheat bran as litter when growing young animals. Among the main points that you need to pay attention to in the first days of the life of chickens is the constant presence of warm drinking water, into which glucose is recommended.
Newborn chickens are fed up to 6 times a day, starting in the first days with a chicken yolk, gradually switching to feed mixtures intended for chicken young animals.
For chickens in the first months of growth during the formation of the skeleton, calcium feeding is required, which may be in the form of crushed limestone. Small shell rock allows for the normal functioning of the digestive system, especially when whole grains are included in the diet of birds.
Advantages and disadvantages for breeding
The important advantages of the breed for the price of a bird are:
- high productivity and growth rate,
- stable egg production,
- easy adaptability to changing conditions of detention,
- quality characteristics of eggs and meat,
- high percentage of viability.
Among the shortcomings that lead to culling of birds in the breed, reducing the prices of individuals:
- the presence in the plumage of a color that is not characteristic of the breed,
- light color of the eye iris,
- mismatch of the metatarsal breed shade,
- low weight
- physique not complying with breed requirements.
Among the minuses of the Jersey breed, reviews of poultry farmers distinguish:
- the need for a large space for keeping birds,
- loss of taste of meat in individuals older than a year,
- breed predisposition to obesity.
In addition, the Jersey giant chickens are prone to mycoplasmosis, because poultry farmers recommend carefully observing the birds in the first 2-3 months. Newly acquired chickens and adults are kept in quarantine separately from the entire livestock.
