Eggs of queen hatch into white, legless larvae, which spin
delicate silken cocoons around themselves and turn into pupae. Each pupa
develops into an adult. The adult comes out by cutting walls of cocoon first
and secondly by breaking the wax sap of the cell.
During
first 2 to 3 days, all larvae of bee are fed on a special proteinaceous food,
called “Royal Jelly”or “bee milk” which is secreted by the
hypopharyngeal glands of the young workers. After that coarser food, the “Bee Bread”, which is a mixture of honey
and pollen grain, is given. However, the queen forming larvae are fed on royal
jelly for the full larval life and these larvae are also taken for further
development into a special chamber called the queen’s chamber or cell.life cycle of honey bee
ü Egg and Broiler Production
There are two basic categories of poultry farming:
[i]obtaining more and more eggs; [ii] getting flesh.
Ø Production of eggs
In chickens, eggs production is the most important trait. A
layer starts laying eggs at the age of 20 weeks. The egg production period in
commercial layer is 500 days.
To develop new varieties or to improve
quality of chicken with respect to quantity and quality of eggs the following
points are considered: [i] Egg number [ii] Sexual maturity [iii] Egg weight [iv]Body
weight [v] Feed efficiency [vi] Egg size [vii] Egg shape [viii] Shell colour [ix] Shell quality and [x] internal quality of
egg.
Ø Production of Broiler
Chickens are raised up to 6-7 weeks in the poultry farm.
They grow to a weight of 700 gram to 1.5 kg in this period. They are fed with
vitamin rich supplementary feed for good growth rate and better-feed
efficiency. Care is taken to prevent mortality, enable feathering, and maintain
carcass quality. They are produced as Broilers and sent to market to be sold as
meat.review:indian egger and broiler production
