Causes of Leg Mites in Poultry
-
Contact with infected birds
-
Dirty housing and poor hygiene
-
Weak immunity due to stress or poor nutrition
-
Exposure via wild birds, rodents, or contaminated tools
-
Moist environments that favor mite survival

1. Energy Management
In cage systems, energy needs are more predictable and primarily divided into:
Growth
Maintenance (≈65% of total needs)
Egg mass production
Ensure energy intake is sufficient to meet maintenance before expecting improvements in egg size.
2. Amino Acid Optimization
Critical amino acids for egg size:
Methionine (Met)
Lysine (Lys)
Isoleucine (Ile)
Secondary amino acids: Threonine, Tryptophan, Valine, Arginine.
These amino acids build albumen and yolk. Deficiencies lead to smaller eggs.
Maintain a balanced profile of 7 essential amino acids, supported by adequate crude protein.
3. Linoleic Acid
Essential for yolk development.
A minimum threshold is required; excess intake does not further increase egg size.
4. Fat Inclusion in Feed
Benefits:
Improves energy balance, sparing amino acids for egg formation.
Enhances feed texture, reducing dustiness and improving palatability.
Example: Increasing oil from 1% to 3% shifts energy sourcing from protein to fat, preserving amino acids for egg production.
5. Body Weight & Development
Target weight at 19 weeks
Early body development (especially by week 6) is critical.
Uniform flock weight ensures consistent egg size and shell quality.
6. Calcium & Phosphorus Balance
Essential for shell formation.
Maintain proper Ca:P ratio (typically 4:1) and include bioavailable calcium sources like limestone and particle size
7. Trace Minerals
Zinc, Manganese, Copper: Support shell strength and reproductive health.
Deficiencies can cause thin shells and reduced laying frequency.
8. Lighting Program
-
feed composition among the most important factor for taste, size, %age, egg shell quality, internal quality, color of yolk, egg bound, fertility, hatchability ,
-
Halogen meter (moisture content), hardness tester(hardness) & PDI tester(PDI).

What tools do you use for pellet quality monitoring?
Sakthivel
-
Pellet ‘s
Discharge temperature ,Moisture content ,Bed depth and resistance time

-
Low starch gelatinization during conditioning.
Incorrect die specifications (thin die, large open area).
Worn-out rollers or die.
High inclusion of fibrous raw materials.
Low steam temperature or short retention time.
Excessive pellet mill load or incorrect knife settings.
Poor cooler operation leading to brittle pellets.

How do you reduce down time during feed change over ? .Pls share your experience

In addition disease factors is also responsible for feather loss.
-
Age of the birds can cause feather loss.older birds are more prominent.
Poor feeds quality.
Poor nutrition regime or underfeeding as found in force moulting.
Ectoparasites such as lice, mice etc.
Growing pullets transitioning to point of lay will moult or shed feathers as a sign of active growth or otherwise known as mitosis.

Methods of Diseases diagnosis in the farm.
*Clinical diagnosis involves looking for clinical signs by Examination of morphological part of the birds, feacal Examination, etc.
*Post mortem Examination involves Examination of visceral organs such as lung ,heart, liver, kidney, spleen, intestines, for certain infection lesions which there conditions are deviated from normal conditions.
*Laboratory diagnosis involves taking serum or blood samples of infected birds for serology test. For example,ELISA test.
As for treatment, use of Antibiotics for treatment of bacterial infections,
Coccidiostats for eimeria infections.
Mycotoxins drugs for treatment of Fungi infections.
-
Necrotic enteritis is a bacterial infection caused by poor litter management and transmission from infected birds Laterally to other birds.
The birds get infected when feeding on dirty litter with infected bacteria.
-
sure.
biosecurity is directly proportional to birds health and disease prevention
-
ddiagnose the sick birds by clinical signs like coughing, sneezing, rales, watery nose or eyes, swollen eyes or head, sitting or standing posture, eyes, wattles, legs appearance or abnormality, belly normal or swollen, feet appearance,
feed and water intake increased or decreased ,
post mortem,
Lab diagnosis
treatment is according to disease diagnosed.
