The liver of a chick is normally fatty (pale, sometimes yellowish) during the early 3-4 days after hatching primarily because of the intense metabolism and mobilization of the residual yolk.
This temporary, physiological “fatty liver” is a normal part of the chick’s transition from an embryo nourished by yolk to a free-living bird consuming feed.
Key Reasons for the Fatty Liver
* Yolk Lipid Mobilization and Absorption:
* The yolk is the primary nutrient source for the embryo, and it’s rich in lipids (fats), which provide about 90% of the energy needed for embryonic growth.
* At the time of hatching, a significant portion of the yolk, known as the residual yolk sac, is pulled into the chick’s body cavity.
* The lipids from this residual yolk are rapidly broken down, absorbed through the intestines and yolk sac membrane, and transported to the liver for processing and distribution throughout the body.
* Hepatic Lipid Accumulation:
* The large influx of absorbed lipids, particularly triglycerides and cholesteryl esters from the yolk, leads to a substantial accumulation of fat droplets (vacuoles) within the hepatocytes (liver cells).
* This accumulation is a necessary step as the liver processes the massive lipid load and repackages it into forms (like very-low-density lipoproteins) for transport to peripheral tissues to fuel the chick’s rapid growth and intense metabolic needs during the post-hatch period.
* Metabolic Transition:
* The chick’s metabolism is undergoing a significant shift: moving from relying solely on yolk lipids (fatty acid oxidation) to utilizing feed-derived carbohydrates and proteins.
* During this short transitional period (the first few days), the liver is working overtime to manage the remaining yolk nutrients, resulting in a temporary, high fat content.
This elevated fat content typically subsides around Day 5 to 7 post-hatch as the residual yolk is largely absorbed and the chick’s metabolism fully adapts to external feed.The liver of a chick is normally fatty (pale, sometimes yellowish) during the early 3-4 days after hatching primarily because of the intense metabolism and mobilization of the residual yolk.

Glutamine supplementation in embryos has been observed to enhance intestinal development by promoting villi length and surface area. It also improves the structure of microvilli, increasing their density and functionality. These changes contribute to better nutrient absorption and overall gut health in developing embryos.Glutamine supplementation in embryos has been observed to enhance intestinal development by promoting villi length and surface area.

The liver of chicks is often fatty during the first 3-4 days after hatching due to several reasons:
-
Energy Reserves: After hatching, chicks rely on the energy stored in their yolk sac, which is high in lipids. The liver accumulates fats as it metabolizes these reserves to support rapid growth and energy needs.
-
Metabolic Adaptation: The liver plays a crucial role in metabolism. In the early days, it adjusts to the chick’s new environment and dietary changes, often resulting in increased fat storage.
-
Developmental Stage: The chick’s body is in a critical stage of development, requiring significant energy. The liver’s fat accumulation supports this energy demand as the chick transitions from relying on the yolk to consuming solid food.
-
Insulin Regulation: Hormonal changes post-hatching, particularly the rise in insulin levels, can promote fat synthesis and storage in the liver.
This fatty liver condition is typically temporary and normal during the chick’s early life as it transitions to a more varied diet.The liver of chicks is often fatty during the first 3-4 days after hatching due to several reasons:

why the liver of chick is fatty during early 3-4 days after hatching?
-
balance feed is according to the nutrients need of the bird like layer or broiler,
layer starter, growing stage, laying stage.
Broiler starter, grower, finisher.
Energy, orotein, essential amino acids, essential fatty acid , vitamins, minerals, enzymes, etc
-
Like to listen about topic
-
Accelerate the protein digestibility, bioavailability & absorption of nutrient.
-
What’s your opinion on using fermented soybean meal to improve digestibility in poultry diets?
-
Use a mix of energy sources (corn, wheat), protein sources (soybean meal, fish meal), minerals and vitamins, plus oils, enzymes, and additives for a balanced poultry diet.

Prevention is better than cure!
We must target to have good algal bloom in our culture ponds rather than having problem and then try finding ways of improvement.
That’s why I mentioned usage of fermented juice to be prioritized against usage of inorganic fertilizers mainly which are very often and openly used by many.
It is one of the very dynamic topic to take forward, discuss and execute but even after having pool of 170+ dynamic professionals in the group at the moment I am not finding it moving ahead.
Come on guys participate and share your experiences and queries for the benefit of those for whom this is a new topic to understand and start using.
Looking forward.
