Big size eggs are caused by <mark>a combination of the hen’s breed, age, overall health, and nutritional intake</mark>. Older, more mature hens lay larger eggs, while certain breeds are genetically predisposed to laying bigger eggs. A hen’s body weight is a key factor, as heavier hens lay larger eggs, which is influenced by adequate nutrition, sufficient feed intake, and proper body weight management from a young age.
Key factors influencing egg size:
<ul jscontroller=”M2ABbc” jsaction=”jZtoLb:SaHfyb” data-hveid=”CDkQAQ” data-ved=”2ahUKEwiBjc3T3aWPAxVbnmMGHSJgEysQm_YKegQIORAB” ahbak=”true” aria-hidden=”true”>
<strong ahbak=”true” aria-hidden=”true”>Hen’s Age:
As a hen gets older, her eggs tend to get larger. Pullets (young hens) lay smaller eggs when they first start producing them, with egg size increasing as the hen matures.
<strong ahbak=”true” aria-hidden=”true”>Breed:
Some breeds are naturally larger birds and therefore lay larger eggs than smaller breeds.
<strong ahbak=”true” aria-hidden=”true”>Hen’s Body Weight:
A heavier hen will lay a larger egg, so maintaining a healthy body weight is important for increasing egg size.
<strong ahbak=”true” aria-hidden=”true”>Nutrition:
A diet rich in protein, calcium, and essential amino acids is crucial for producing larger eggs. Deficiencies can lead to smaller eggs.
<strong ahbak=”true” aria-hidden=”true”>Nutrition Management:
Providing a high-protein layer ration and ensuring sufficient feed intake are important for egg size. Limiting factors like heat stress, crowding, and inadequate water supply can reduce egg size by limiting nutrient intake.
<strong ahbak=”true” aria-hidden=”true”>Light Programs:
The length of daylight influences when a hen starts to lay, which can affect egg size. Delaying the onset of laying through careful light programs can increase the size of the eggs.
<strong ahbak=”true” aria-hidden=”true”>Feed Consumption:
Any factor that limits a hen’s consumption of feed, such as heat stress or overcrowding, can reduce the size of her eggs.

Dietary arginine improves broiler breeder hatchability by <mark>supporting the immune system, increasing egg production and size, and potentially enhancing embryo development</mark>. Magnesium oxide contributes to overall health, muscle growth, and energy levels, which are crucial for egg production and the viability of the embryo. While specific dietary recommendations vary, studies suggest digestible arginine levels around 1.26% to 1.54% and magnesium oxide levels around 3-4 pounds per ton of feed for broiler breeders can optimize performance.

Thin eggshells in layer birds are often caused by a <mark>lack of calcium or vitamin D, poor nutrition, high stress, certain diseases like Egg Drop Syndrome, environmental factors such as extreme heat or poor ventilation, and the age of the hen</mark>, with older birds and sometimes very young layers producing weaker shells.

There isn’t a simple physical method for a feedmill to check for gelatinization during conditioning; instead, enzymatic methods, like the glucoamylase method, and advanced techniques such as Near Infrared (NIR) spectroscopy are used in feed mills to quantitatively measure the degree of starch gelatinization after processing. These laboratory methods assess the chemical changes that occur when starch granules absorb water, swell, and become more digestible, which is the core of gelatinization.

I will love to know this too.
-
What are laboratory tests to perform to evaluate the conditioning process efficiency and gelatinization being done properly?
-
How can we check physically gelatinization process being done during conditioning ? If there any physical method to measure or evaluate?
-
What is ideal conditioning Parameters to achieve good mesh feed gelatinization and achieve better pellets?

As we all know dissolved oxygen (DO) is one of the very important parameter for any living being so as for fish and shrimps during culture at all stages. Let us discuss on some important queries which gets generated related to these<
1. What is the ideal DO level in the pond?
2. Why does DO level fluctuate during the day?
3. What are the main causes of low DO?
4. What are the symptoms of low DO in ponds?
5. How can DO be improved or maintained?
6. What is the best aeration strategy?
7. When is DO most critical in the ponds?
8. What is / are right timing/s of checking DO in the pond?
9. Does pro-biotic has any role in DO management in the pond?
You can participate in answering all or any number of questions; are requested to mention same number whose answer you are giving.

Many good points mentioned by many participants defining Pelleting.
Now let us take it forward discussing PROS and CONS of pelleted feed with especial reference to Aquaculture – Fish and Shrimp.
Looking forward for active participation and queries related tot hat from you all 130+ dynamic professionals.

A very broad question, answering in brief – We can take discussion forward about any of these points for clarification, and better understanding
1. Site selection – Including nature of soil, it’s topography, salinity based on species & accessibility
2. Water quality parameters – Temperature, salinity, pH DO, Transparency & Alkalinity to optimum levels
3. Pond designing to suitability & Pond preparation to requirements
4. Quality of Post-larvae
5. Nutrition, Feed & Feeding including right type of feed required, its composition species-wise, right feeding calculation, evaluation & methodology for effective utilization and best conversion
6. Biosecurity – Starting from postlarvae to routine farm management related aspects
7. Health – Connected to ecology and immune system to be taken care, observed and ensured all through culture duration.
8. Management practices – To minimize wastage, control ecology well, C:N ration plays an important role for the same to be maintained well
9. Avoid any kind of sudden change, shocks & stress to shrimp at all stages during culture

Very true but changing water will help you temporarily to restore and save your biomass.
If you are looking for problem free culture further you need to find out root cause of such happening as I have listed earlier and once you get confirmed, attend solving it so that such condition does not arise again.
If root cause is not find out and attended, such happenings will repeat and it may bounce against sometime and result to biomass loss.
So evaluate and rectify on cause.
