This document discusses light requirements for egg production in layers. It defines various light measurement terms like lumen, foot candle, and lux. It describes the types of light sources used in poultry houses and how lights should be installed. The effects of light on egg production during growing and laying periods are explained. Light programs are outlined for in-season and out-of-season flocks in open-sided houses, with recommendations to increase light hours gradually over time to achieve peak egg production.
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.
A broiler management course is a program designed to educate farmers, poultry producers, and other interested individuals on the best practices for managing broiler chickens. Broiler chickens are raised for meat production and require specialized care to ensure their growth, health, and well-being. The course typically covers various aspects of broiler management, including housing, feeding, health management, and disease prevention. It may also cover topics such as breeding, hatching, and marketing of broiler chickens. Participants in a broiler management course will learn about the different types of broiler housing and the best practices for managing temperature, ventilation, and lighting to ensure optimal growth and production. They will also learn about the various types of broiler feed and how to formulate a balanced diet that meets the nutritional requirements of broiler chickens. Health management is a critical aspect of broiler management, and the course will cover topics such as biosecurity measures, vaccination programs, and disease diagnosis and treatment. Participants will learn how to recognize common health problems in broiler chickens and how to implement preventative measures to keep their flocks healthy. Marketing is also an important aspect of broiler management, and the course may cover topics such as market analysis, pricing strategies, and distribution channels. Overall, a broiler management course provides participants with the knowledge and skills needed to raise healthy, productive broiler chickens, and to operate a successful broiler farming business.

This is an essential tool for poultry management. Lighting is the unavoidable management practice for successful poultry rearing. Present ppt prepared based on the basic rule of light required for chicken with practical aspect. I hoped students will be benefited with this presentation.
A good poultry health management is an important component of poultry production. Infectious disease causing agents will spread through a flock very quickly because of the high stocking densities of commercially housed poultry.
For poultry health management to be effective a primary aim must be to prevent the onset of disease or parasites, to recognize at an early stage the presence of disease or parasites, and to treat all flocks that are diseased or infested with parasites as soon as possible and before they develop into a serious condition or spread to other flocks. To be able to do this it is necessary to know how to recognize that the birds are diseased, the action required for preventing or minimising disease and how to monitor for signs that the prevention program is working.

Modern hybrid layers can be reared successfully in floor and cage brooding systems in developing countries. However, they need more careful management than village chicks, which are better able to cope with temperature fluctuations.
Prior to chick arrival, it is important to clean and disinfect the cages or the floor brooding area. The brooders should be set up the day before delivery, at 34 to 36 °C for cage brooding or 35 to 36 °C for floor brooding. Drinkers need to be full or the drinking system in operation, to encourage birds to drink. If nipple drinkers are used, the water pressure should be reduced so that birds can see the drop of water hanging on the drinker. Feed should be placed on paper if birds are reared in cages. Feeders on the floor should be filled and kept under high light intensity for 20 to 22 hours per day for the first week, to attract the birds.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Light requirement in layer
1. LIGHT REQUIREMENT IN LAYER
PREPARED BY; M.AZAM SHAHZAD &
MUHAMMAD UMAIR
SEMESTER ; 10TH (MORNING)
SESSION ; 2010-15
UCV&AS
THE ISLAMIA UNIVERSITY OF BAHAWALPUR
3. Role of light
on egg
production
The egg production is
associated with the length
and intensity of the light
Light
anterior lobe of
the pituitary
gland
GnRH FSH,
LH
4. Terms regarding light
The lumen is defined as
the rate at which light
falls on a square foot
area surface which is
equally distant one foot
from a source whose
intensity is one candela
Lumen
6. Foot candle
A foot candle is defined as
the intensity of light striking
each and every point on a
segment of the inside
surface of an imaginary one-
foot radius sphere with a one
candlepower source at the
center
8. Lux
A lux of light intensity is
equal to one lumen per
square foot
1 foot candle = 10.76 lux
9. TYPES OF LIGHT
There are four common light types used in poultry
houses are
Incandescent – Cheapest; necessitates reflectors,
short bulb life (750-1000 hrs)
Fluorescent – 3 to 4 times more efficient than
incandescent
bulbs; 10 times longer life than incandescent bulb
Mercury vapor – Long life (24,000 hrs); requires
several minutes to warm up; cannot be used in
houses with low ceilings.
11. THE MANNER IN WHICH LIGHTS ARE
INSTALLED IN THE POULTRY HOUSE
The distance between bulbs should be 1½ times the distance
from the bulb to the bird level
The distance from the bulbs to the outer edges of the house
should be only ½ the distance between bulbs
In cage system, the bulbs should be placed in such a way that
their rays fall on the feed and on the birds
Clean reflectors increase the light intensity at bird level by 50%,
compared with no reflector
Avoid cone shape reflectors since they confine the light rays to
limited area. Better to use flat type reflector with rounded edge
In case of deep litter system, the bulb is to be placed at 7-8’
height whereas in cage house, keep in aisle
12. CONTI…
Avoid hanging bulbs by a cord in open
houses
Very dirty bulbs emit about 1/3 less
light than clean bulbs.
Light bulbs should be cleaned once in
two weeks.
15. LIGHT EFFECTS DURING GROWING PERIOD
Decreasing the length of light day during
growing period will lead to
Increase the age at sexual maturity
Increase the number of eggs laid during the
first half of the egg production (but not in total
number of eggs laid)
Increase the size of the first eggs produced
16. LIGHT EFFECTS DURING LAYING
PERIOD
Birds reared under increased day-light produce more
eggs due to the release of FSH and LH from the
pituitary
1 ft candle light intensity is needed in layer houses
In multi-deck cage system, minimum of 0.5 foot
candle light intensity is needed at the lower deck
For maximum egg production, 16 hours light is
needed during peak egg production period
Reducing photoperiod during laying period seriously
affects egg production
17. In-season
flocks
Those birds grown during a
period when the length of the
natural light day is decreasing, at
least during the last part of their
growing cycle are called in-season
flocks
As a general rule, chicks
hatched between August 31st and
March 1st
19. light programs in open-sided
houses
In-season
flock
No artificial light is needed
up to 20 weeks At 20
weeks of age increase the
light to 13 hours.
Then add 1 hr per week
until it attains 16 hours light.
20. Out-
season
flock
i) Determine the length of the
longest natural light day before
the pullets reach 20 weeks of
age. Maintain this period of
daily light hours from the 3rd
day until 20 weeks by
supplementing artificial light
with natural light. Then
increase 1 hour of light at this
stage and increase 1 hour every
week until it reaches 16 hours
total light period
21. Determine the total natural day-light hours
when the pullets reach 20 weeks of age. Then
add 7 hours. This represents the length of the
light day from the 3rd day. Thereafter reduce the
length of light day by 20 minutes per week. At
20 weeks of age increase the length of the light
day by 1 hour. Then increase 1 hour per week
until it attains 16 hours light per day.
