FLOCK UNIFORMITY PPT- POULTRY RAISING ANIMAL PRODUCTION

ANIMAL PRODUCTION-POULTRY RAISING GRADE 9

1. FLOCK UNIFORMITY

2. What is FLOCK UNIFORMITY?

3. Uniformity  indicates the percentage of flock that falls within a certain range of the average flock bodyweight (mean) . This certain range is usually ±10% of the mean.

4. So, the greater the uniformity, the less variable a flock is.

5. STEPS IN SOLVING THE FLOCK UNIFORMITY

6. STEP 1

7. Step 2

8. Step 3

9. Step 4 Find out the number of birds that within the range if +10% and -10% Example: +10%= 385 grams -10%= 315 grams 300 320 340 360 380 400 = 4 birds

10. Step 5 Calculate the UNIFORMITY Formula: (Total of birds within the +10% and -10% range / Total No. of birds )*100 4 birds/6 birds= 0.66666*100 Uniformity is = 66.6666 = 67% Note: Flock Uniformity should be 80% and above , below 80% means poultry management needs to be reviewed to ensure uniformity of flock in the farm.
