CHICKEN BREEDS
        General Information
        India has made considerable  progress in broiler production in the last two decades. High quality chicks,  equipments, vaccines and medicines are available. With an annual output of  41.06 billion eggs and 1000 million broilers, India ranks fourth largest producer  of eggs and fifth largest producer of poultry broiler in the world. The broiler  production has also sky rocketed at an annual growth rate of about 15 percent  at present. Broiler farming has been given considerable importance in the  national policy and has a good scope for further development in the years to  come.  
         Advantages of Chicken farming
        
          - 
            
Initial       investment is a little lower than layer farming. 
           
          - 
            
Rearing       period is 6-7 weeks only. 
           
          - 
            
More       number of flocks can be taken in the same shed. 
           
          - 
            
Broilers       have high feed conversion efficiency i.e. least amount of feed is required       for unit body weight gain in comparison to other livestock. 
           
          - 
            
Faster       return from the investment. 
           
          - 
            
Demand for       poultry meat is more compared to sheep/Goat meat.

          Grower: The  management of birds during 9-20 weeks or to the point of laying is
          referred to  as grower period. 
        Layer: The management of birds during  21-72 weeks of age for the purpose of laying eggs (egg production).

        Breeds of Chicken 
           
        Chickens  are grown for their egg and meat. Likewise they are classified as egg-type  chicken and meat-types chickens. Egg type chickens are composed of stock that  has been developed for egg production and are maintained for the principal  purpose of producing chicks for the ultimate production of eggs for human  consumption. Breeds of meat type chickens primarily include broilers, fryers,  roasters, and other meat type chickens. Here broilers and other chickens are  raised for their meat. Broilers are genetically selected for fast growth and  raised for meat rather than eggs e.g. White Synthetic Male line (WSML), white  synthetic dam line (SDL), coloured synthetic male line (CSML), coloured  synthetic female line (CSFL), introgression of frizzle gene etc.

        Indigenous Breeds 
         
        The  common control hen, the desi, is as a rule the best mother for hatching. She is  a good forager. Some of the Indian flows resemble the Leghorn in size and shape, but have poor  laying qualities. They are Found in various colours. one variety found in India resembles the sussex or Plymouth Rock in shape  but is smaller. These birds lay family well and are more common in the eastern  parts of the country.  
         
        The Indian birds are mostly  non-descripts, and are of very little value as layers. They have several local  breed names such as Tenis, Naked Neck, Punjab,  Brown, Ghagus, Lolab, Kashmir Faberella, Tilri, Busra, Telllicherry, Danki,  Nicorai and Kalahasti. There are only 4 pure breeds Karaknath and the Busra.  The last occurs in western India.  A large number of flows of different size, shapes and colours, and for the most  part resembling the jungle fowls, are found all over India. They vary in  appearance according to the locality in which they have been bred. These with Chittagong, Aseel,  Langshan or Brahma blood in them are bigger in size and better in meat quality  than the common flows.  
        Asil 
   
        Asil is noted for its pugnacity,  high stamina, majestic gait and dogged fighting qualities. The best specimens  of the breed, although rare, and encountered in parts of Andhra Pradesh, Uttar  Pradesh and Rsjasthan. The most popular varieties are peela (golden red),  yarkin (black and red), Nurie 89(white), kagar (black), chitta (black and white  silver), Teekar (brown) and Reza (light red). Although poor in productivity,  the birds of this breed are well-known for their meat qualities. Broodiness in  most common and the hen is a good sitter and efficient mother. They possess pea  combs which are small  but firmly set on  head. Wattles and ear lobes are bright red, and the beak is hart. The face is  long and slender, and not covered with feather. The eyes are compact, well set  and present bold looks. The neck is long, uniformly thick but no fleshy. The  body is round and short with broad breast straight back and close - set strong  tail root. The general feathering is close, scanty and almost absent on the Brest. The plumage has  practically no fluff and the feathers are tough. The tail is small and  drooping. The legs are strong, straight, and set well apart. Standard weight (kg): Cocks, 4 to 5;  hen 3 to 4; cockerrels, 3.5 to 4.5; pullets, 2.5  to 3.5. 
         
          
        Asil 
        Karaknath 
   
        The original name of the breed seems to be  Kalamasi, meaning a fowl with black flesh. However, it is popularly known as  Karaknath. The eggs are light brown. The day-old chicks are bluish to black  with irregular dark stripes over the the back. The adult plumage varies from  silver and gold-spangled to bluish-black without any spangling.  The skin, beak, shanks, toes and soles of  feet are slatelike in colour.The comb, wattles and tongue are purple. Most of  the internal organs show intense black colouration which is pronounced in  trachea, thoracic and abdominal air-sacs, gonads and at the base of  the heart and mesentery. Varying degrees of  block colouration are also seen in the skeletal muscles, tendons, nerves,  meninges, brain etc. The blood is darker than normal blood. The black pigment  has been due to deposition of melanin, The flesh although repulsive to look at,  is delicious. A medium layer, lays about 80 eggs per year. The bird is  resistant to diseases in its natural habitat in free range but is more  susceptible to Mareks disease under intensive rearing conditions.
