Hello and greetings
Friends to remove and keep productive
What do you think about these numbers and filters (during a production period of about 8 months)?
First step: I just check the number of eggs and divide them into 3 categories:
Category 1: Chickens with 50 eggs and above
Category 2: 25 chickens
Category 3: 12 chickens
The result of the first stage of elimination of category 3 chickens
The second stage (review of categories 1 and 2):
Fertilization check (of course, this is a bit different from the third stage of roosters) + survival check or the number of chicks
Fertility:
Category A: You have 35 sperm
Category B: 17 items
Category C: 8 items
This part needs to be explained more (assuming that the rooster is healthy in all cases and if the number is low, the hen is not receptive to the rooster or something else)
survival;
Category A: Number of 20 chicks from 35 fertilized eggs
Category B: 10 pieces out of 35
Category C: 5 pieces out of 35
third level:
Examining the percentage of sperm in roosters
1. Rooster with 70% sperm and above
2. Rooster 50 to 70%
3. Rooster below 50%
Final level:
The result of these three stages and field decision-making and consultation with the workers of each breeding hall, checking the quality of the skin, the age of the bird, and the birth certificate.
Description:
* In this program, pre-productiveness and special things that should be paid attention to are not included
** And it is better that in each of the stages apart from the numbers, it is better to include the percentage so that you can make a decision easily.
