For better poultry farming, cognizance about different breeds should be important. To go either layer or broiler farming, breeds are the considerable factors. All are differentiated in terms of their geographical distribution, utility, colour etc.
Layer poultry farming means raising egg laying poultry birds for the purpose of commercial egg production. Layer chickens are such a special species of hens, which need to be raised from when they are one day old. They start laying eggs commercially from 18-19 weeks of age.

All of the above poultry-keeping methods are used in the developing world,but the majority of the enterprises are backyard poultry and farm flock production. The poultry and egg sectors are highly fragmented. Most of the production is carried out by a large number of farmers, each with a very small flock. The greater part of produce is sold in markets close to the farms.
Day-old chicks are usually obtained from local hatcheries licensed by international hybrid breeding companies. Farmers or cooperatives of farmers may choose between varieties of chickens for egg production and meat production.
The small chicks can be either naturally or artificially brooded. If artificially brooded, small chicks must be placed in a separate house from laying chickens and it is necessary to protect the chicks from predators, diseases and catching colds.
This stage of brooding lasts for eight weeks. In the first four weeks of life, small chicks need to be housed in a brooding box. Some typical types of brooders are shown below and on the previous page.
Typically, a layer’s production cycle lasts just over a year (52-56 weeks). During the production cycle many factors influence egg production; therefore, the cycle must be managed effectively and efficiently in order to provide maximum output and profitability.

They remain laying eggs continuously till their 72-78 weeks of age. They can produce about one kg of eggs by consuming about 2.25 kg of food during their egg laying period. For the purpose of producing hybrid eggs layer, consider the various characteristics of cock and hen before breeding. There are various types of highly egg productive layer breeds available throughout the world.

Poultry production systems refer to the different ways that poultry (chickens, turkeys, ducks, etc.) are raised and managed for their meat, eggs, or both. The two primary poultry production systems are conventional and alternative systems.
Conventional poultry production systems involve raising large numbers of birds in indoor confinement with controlled environments, such as temperature, ventilation, and lighting. The birds are often kept in cages or on the floor, and their feed, water, and lighting are controlled. This system aims to maximize production efficiency and minimize costs.
Alternative poultry production systems, on the other hand, aim to provide a more natural and humane environment for the birds. These systems can include free-range, organic, or pasture-based systems, where the birds have access to the outdoors and are allowed to exhibit natural behaviors, such as foraging for food. These systems often require more labor and management compared to conventional systems, but they can provide benefits such as improved animal welfare and enhanced product quality.
Poultry production systems can also vary depending on the purpose of production, such as meat, eggs, or breeding. For example, meat birds are typically raised in a broiler production system, while laying hens are raised in a layer production system. Breeder birds, which are used for producing eggs for hatching and raising the next generation of birds, are raised in a breeder production system.
Overall, the type of poultry production system used depends on various factors, such as production goals, market demands, and available resources.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Editor's Notes
There has always been the question of which came first, the chicken or the egg? In the case of layer hen houses the chicken comes first. Chickens are received from pullet houses when they are 21 weeks old. Soon (21-25 weeks) the chickens will begin laying eggs that will be sent off to the hatcheries to be hatched. The chicks will be put back into broiler chicken houses.
The objective of this presentation is to explain the operations of a layer hen house. Many other important factors go along with layer hen houses such as: determining the resources needed, learning about the house contracts made with the company and knowing about the equipment needs for the layer house. We will also learn about the reproductive cycle of the chickens in the house and will define the time line of layer house production.
Layer hen houses are used to produce eggs that will be sent to hatcheries. These eggs are then hatched and the chicks are put back into broiler chicken houses. If the eggs are too big (double yoked), if the eggs are too small or if the eggs have improperly formed shells they cannot be sent to the hatchery. The double yoke eggs and small eggs are boxed and sold to other companies for uses such as dog food. If the eggs are too small (sometimes they are the size of bird eggs) or if the eggs are jelly eggs they are thrown away; otherwise, they are cleaned, placed in buggies, and picked up by the egg truck to be taken to the hatchery.
Layer houses and layer hen houses, while both produce eggs, they have entirely different purposes.
Layer houses are used to produce eggs for human consumption. These are the eggs that are found in grocery stores. For this type of house, no roosters are necessary to fertilize the eggs.
Layer hen houses also produce eggs but for an entirely different purpose. The eggs produced in a layer hen house are fertilized so that the eggs can be hatched and put back in broiler houses. Roosters are an absolute necessity for the layer hen houses so that the eggs can be fertilized. Eggs must also be especially taken care of to protect the embryo’s growth.
Walk the house:
3-4 times daily
Pick up dead birds, ensure that eggs have rolled into nests and no dead birds are in nests
Weigh and run the feed:
The feed needs to be weighed once a day so that the chain feeders can run the food throughout the house once a day
Recording egg production and mortality:
Eggs need to be counted and the number recorded each time eggs are picked up
Eggs are picked up 3-4 times a day
At end of day, the egg count is totaled and recorded
Record # of dead birds after each walking; then total and record dead birds at the end of the day
Lights:
Lights are used to maximize egg production
Set to come on at 4:30 am
Set to go off at 8:00 pm
Lights are always set on standard time; does not change with daylight-savings time (chickens do not understand time change)
Maintaining House Temperature:
House temperature needs to be kept no cooler than 65º F in the winter and no hotter than 85º F in the summer.
Feed Truck:
Feed truck comes once a week
Egg Truck:
The egg truck will come two times a week to pick up the eggs in the buggies and eggs in the boxes
The egg truck will drop off new buggies to be filled for the next visit.
Picking up eggs:
Eggs have to be picked up 3-4 times daily
Pick up needs to start in the early morning so eggs are not left out during the day on conveyor belts. If eggs are picked up as soon as possible, the egg will not be as dirty and the embryo will be healthier.
Eggs have to be sorted by size and abnormality and put into trays
Eggs have to be cleaned (without using water to keep hatchability rates high), placed in egg trays, and then put into buggies
Eggs too small or too big are put into boxes, and eggs that are jelly (soft shell) or that have cracks are thrown away.
Eggs are placed in the cool room at 65º F to stop the embryo from growing until it reaches the hatchery
Hens and roosters are needed for the layer hen house. The number of hens and roosters put in a layer house depends on the number of chickens coming from the pullet house. The company does however, like to have one rooster for every ten hens. Other important resources for the layer house are feed and water.
Feed is brought to the house once a week. The feed is weighed and run from the scale room by chain feeder once daily.
Water is an important factor in chicken houses. Water is always there for the chickens to drink.
Medication is run through the drinkers so that all chickens will remain healthy.
Finally, what would a layer house be without labor. Someone has to be in charge of the house and responsible for picking up the eggs, walking the house and weighing feed.
The company pays for:
Chickens
Feed
Medicine
Egg trays and buggies
The grower is responsible for:
Water
Electricity
Propane
Disposal of dead birds
Wash down
Clean out
Shavings
It is important to note that house contracts vary by company. Some companies pay for more and some companies pay for less.
Chickens are moved from pullet houses to layer houses when they are 21 weeks old.
They start laying at around 21-25 weeks of age.
After eggs are picked up, they are placed in buggies and put in a cool room to stop the embryo from growing. The eggs are picked up by company trucks and taken to the company hatchery.
Here the eggs are hatched, and the chicks are sent to broiler chicken houses.
New roosters may be added to replace older roosters that have died to keep egg production steady
The chickens that were in the layer house are sold to other companies for various uses such as soups.
Many elements make up a layer hen house operation. The dimensions of the house are around 40ft X 500ft with an egg room around 25ft X 40 ft. The most common design is slatted floors on either side of a 12-15 foot center aisle of shavings and litter.
The scale room and feed bin area is also very important because it is where you weigh and run the feed. Every day the grower has to go to the scale room to weigh feed. After the feed has been weighed, the feed is dumped into the feed bin and held there until the chain feeders turn on and run the feed throughout the house.
The generator and alarm are very important pieces of equipment. The alarm lets the grower know that the house has lost electricity. When electricity is lost to the house, the generator has to be turned on so that there is water for the chickens and so that the temperature is kept within a reasonable range.
In newer houses there is a conveyor belt under the nests that moves the eggs down to stations so that the eggs can be picked up. In older houses, the grower has to walk through the house and pick up eggs.
The cool room is where the eggs are placed after they are picked up. Eggs are kept at 65º F to keep the embryo from growing until the egg reaches the hatchery.
Hens go to nests to lay eggs, drinkers are set at 18 inches high and are used for supplying water and medication to the hens and roosters. The feeder chain runs the feed throughout the house.
Cool cells and fans are used during the summer to keep the chicken house set at a specific temperature so that egg production will remain high. During the summer it doesn’t need to be hotter than 85º F and in the winter it needs to be no cooler than 65º F. Lights are a very important factor, and it is important to replace all bulbs that are not working. Egg production can be either slowed or stopped by changing the amount of light. Chickens are kept on a lighting schedule to maximize their laying ability. Curtains along the side of the house are used to keep the house cool. If the temperature gets to high the curtains will automatically drop.
Modern layer houses are highly mechanized but there is still a lot of labor involved.
It is important that the producer have a good working knowledge of the equipment and good Ag mechanics
skills
Chickens that are put into layer houses are received from pullet houses when they are around twenty-one weeks old. When the chickens reach 21-25 weeks of age they begin to lay eggs. The chickens will begin to peak (80% of hens are laying) and stay at peak for about 2 months.
New roosters will have to be brought in because the mortality rate will go up. Because the roosters are responsible for fertilizing so many hens(close to 10), they wear out fast and begin to die off. After staying at peak for about two months the egg production slowly goes down.
The chickens are kept in the house until they are sixty-five weeks of age. When they reach that age the company picks the chickens up and sells them to other companies.
Clean out of the begins as soon as possible after the chickens are picked up.
Drinkers, nests, and feeders are raised
Slats are removed
Nest pads are taken out of nest. They are then soaked in disinfectant and cleaned.
Litter and shavings are cleaned out.
Slats are put back in
New shavings are delivered
Nest pads are put back in nests
Drinkers, nests and feeder chain are lowered
Receive next batch of chickens in about 8 weeks.
