Third Quarter Syndrome Flashcards
A collective group of signs and symbols occurring every 3rd quarter wherein poultry and other livestock do not perform as well comparedto the rest of the year
Poor production efficiency
Low ALW, feed intake; longer growing days; high mortality rate, FCR; chick quality issues
Third Quarter Syndrome
Philippine Climate Types
Type I - dry from Nov to Apr, wet during rest of the year
Type II - no dry season with pronounced rainfall from Nov to Apr, wet during rest of the year
Type III - seasons are very pronounced, relatively dry from Nov to Apr, wet during rest of year
Type IV - rainfall is more or less evenly distributed through the year
Farms that are more likely to experience 3Q syndrome are in _ and _ climate
Top performing farms are mostly in _ and _ climate
3QS - Type I and III
Top Performing - Type II and IV
Schedule of Tropical Cyclones
10-14 TCs from Jul to Dec 2018
Coastal regions/river basins = cloud formations = high relative humidity
Amount of water in the air relative to saturation amount the air can hold at a given temp
Relative humidity
RH and Comfortable Climate
Temperature/Humidity Index
Temperature + Relative Humidity = 90 + Age in Weeks
Reeduction in Feed Intake
High Levels of Moisture
Wet litter
Wet litter causes: nutrition, diarrhea, management
Wet litter consequences: animal welfare, diseases, loss in performance, foot pad lesions
Other 3rd Quarter Issues
RH and Grain Quality
Fungal Growth and Mycotoxins
Storage Time and Planting and Harvest Season of Corn
Planting and harvest season in the Philippines for corn
Import: Old stocks (from 3Q harvest of prev year)
Local sources: New stocks (new harvest)
New Harvest Syndrome
Non-starch polysaccharides
Key takeaway
Relative humidity, feed quality, stress, health problems, production problems
Managing 3rd Quarter Syndrome
- Managing RH by proper ventilation
- Management of wet litter
- Coccidiosis control - strategic use of anticoccidials (peak coccidial oocyst shedding normally around 3-4 weeks)
- Control of bacterial enteritis (clinical coccidiosis + subclinical coccidiosis = dysbacteriosis)
Gut health and bone disorders, mold inhibitors and toxin binders, NSPs as antinutrients
