This document provides information on poultry feed formulation by Dr. C. Seenivasan. It discusses the process of quantifying feed ingredients to meet poultry nutrient requirements. It describes different feed types and classifications of ingredients including protein sources, energy sources, vitamins, and minerals. The document outlines the nutrient requirements for broilers and layers at different growth stages. It also discusses the poultry digestive system and key aspects of least cost feed formulation such as raw material and processing costs. Sample feed formulations are provided for broiler pre-starter, starter, and finisher feeds.
The objective of a defined feeding management program is to supply a range of balanced diets that satisfy the nutrient requirements at all stages of development & that optimize efficiency and profitability without compromising bird welfare or the environment.

The liver is the central laboratory of a chicken’s body. It is essential that this organ is kept in an excellent condition in order to maintain a healthy bird. Understanding the metabolic function and causes of disruptions in liver functions helps us to provide the birds with the right feed and health treatment.
When we cut open the body of a chicken, the first organ that is most likely revealed is the liver. The message is clear. Nature wants us to examine the liver carefully before
proceeding to the other organs.The liver contains great functional reserve capacity, which is very important in domestic animals subjected to high production requirements. This organ adapts easily to different conditions by increasing the intensity of its functions.
Particularly in broilers, the liver has to cope with many challenges, including
high energy level feed, the addition of chemotherapeutics, coccidiostats
and others, whose desired metabolites must be maintained in equilibrium by hepatic homeostasis.Incidental treatments with highly hepatotoxic and nephrotoxic antibiotics
or sulfonamides pose serious risks and cause situations of difficult prognosis during a 40-45 day period in which the body acquires satisfactory muscular mass. What is the function of the liver and what might be the cause of malfunctioning?

Inoculation with a specific biological substance (antigen) to stimulate resistance or immunity to a particular disease.
Purpose of vaccination
To prevent or reduce problems that can occur from infection of a field strain of a disease organism
To incite high levels of immunity to protect birds in the face of aggressive endemic disease challenges.
To prevent heavy losses in the form of high mortality, morbidity and lowered protective performance by building up resistance in birds
To hyper immunize hens to maximize maternally derived antibody passed through the egg to the hatching progeny.
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.

Novel Protein Foods: Alternative Sources of Protein for Human Consumption Neeleshkumar Maurya
Proteins are a major macronutrient of the human diet needed for survival. Its crucial function in nourishment is to provide sufficient amounts of amino acids to the body as these amino acids work as anaplerotic substrates in the building block of the body. As the growth of population increases continuously, the demand for protein also increases over the next decades, and it is very important to search alternative sources of protein for human consumption. The present food industrialists aim to develop a cheaper, protein rich that have almost essential amino acids with highest bioavailability and more convenient food products. Single cell protein from algae and fungi, leaf protein extract and many insects could be an alternative of protein, because they have almost all the essential amino acids required for the human body for the survival.
This lecture is presented by our volunteer Talha Saleem, he is from Karachi Pakistan, and he is covering Single cell protein topic.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.

Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
2. Poultry Feed Formulation
It is the process of quantifying the amounts of feed
ingredients that need to be combined to form a single
uniform mixture (diet) for poultry that supplies all of
their nutrient requirements.
Feed types: Mash, Pellet & Crumbles
9. Ca & P sources
1.Dicalcium Phosphate (Ca:21% & P:16%)
2.Monocalcium Phosphate (Ca:16% & P:21%)
3.Shell Grit (Ca:37%)
4.Lime stone Powder (Ca:32%)
5.Lime stone Grit (Ca:33%)
10. Micro Ingredients
Amino acids:
Its two type like essential and nonessential amino acids.
Essential amino acids:
EAA are not produced in sufficient quantities by poultry, so they must be
supplemented to create a well-rounded diet.
Nonessential amino acids:
NonEAA are generated by the body in adequate supply when basic feed
requirements are met.
11. Vitamin Premix:
Vitamins are organic compounds poultry need in small quantities to support
normal body functions, healthy reproduction, and optimal growth rates. Vitamin
deficiencies often lead to disease or syndromes.
Minerlas:
Minerals are required for a variety of roles in poultry health. These include
the formation of bones and red blood cells, correct muscle function, blood clotting,
energy metabolism and enzyme activation.
12. Poultry Feed Formulation
Acidifiers
The major purpose of using this acidifier is to improve
growth performance and better profitability in poultry production.
Organic acids have multi usages in poultry feeds as they help in
preservation to control microbial growth, reduction of the feed
buffer capacity, inhibition of pathogenic bacteria and betterment
of nutrient digestibility.
14. Enzymes:
A substance produced by a living organism which acts as a
catalyst to bring about a specific biochemical reaction. Its
support to digestion.
Phytase:
Used to breakdown of phytic acid (myo-inositol hexso
phosphate) – an indigestible, organic form of phosphorus that is
found in grains and oil seeds – and releases a usable form of
inorganic phosphorus.
15. Liver Powder:
Its support to prevents liver damages and upnormal
growth from feed toxins like mycotoxins, chemical toxins,
Fertilizers and Pesticides.
Antibiotics:
Antibiotic is a drug that inhibits or kills the growth of
pathogenic bacteria within the chicken. It is used to treat
diseases and respiratory infections that maybe be caused by
bacteria.
16. Antioxidants:
Antioxidants are involved in the prevention of cellular
damage, which is. commonly responsible for aging and a
variety of diseases. Antioxidants ar molecules, which can
safely interact with free radicals and terminate the chain.
17. Probiotics:
Probiotics are a dietary supplement that increase the
population of the good bacteria (micro flora), which are needed in
the intestinal tract in order to process food properly. The use of
probiotics as a daily supplement has become a popular routine in
the commercial poultry industry.
18. Toxin Finder
•Mycotoxins are small and quite stable molecules which are extremely difficult to
remove or eradicate, and which are considered to be a great threat both for human and
animal health in global terms.
•Espicially in farm animals, mycotoxins can cause decreased performance, reducing in
feed consumption, weakening of immunity system, reproductive disorders, diminished
body weight gain and residues on food products of animal origin.
•The mycotoxins of major concern as feed contaminants that are potentially removable
from feed, are mainly aflatoxins, ochratoxin A, zearalenone, deoxynivalenol, T-2 and
fumonisins. One of the methods for reducing the exposure to mycotoxins is to reduce
their absorption and bioavailability by using various mycotoxin binders.
19. Poultry Feed Formulation• The most widely known of these are aluminosilicates like clay, bentonite,
montmorillonite, zeolite, aqueus hyderated sodium calcium aluminosilicate
(HSCAS) and active carbons.
• Another method is the degradation of mycotoxins into non-toxic
metabolites by using indigestable complex carbonhydrates (bacterium and
yeast cell walls), enzyme, vitamin, amino-acid and synthetic polymers like
cholestralamine, polivinil-polypyrrolidone polymers (PVPP).
• The purpose of this review points out the benefits and risks of the most
commonly used toxin binders as feed additives in poultry and ruminants.
