We know in practice that chicks often don’t get fed immediately after hatching because of transportation from the hatchery. What kind of negative effects do you think that delay might be causing that we don’t immediately see?

Professor Applegate calls the first days a “critical window” where nutrition directly impacts long-term performance. How does this finding influence how you manage your brooding period, from feed formulation to lighting programs?

Copper (Cu) toxicity in broiler chickens is generally observed at levels of 250 \text{ mg/kg} of feed and above when provided as a supplement (e.g., cupric sulfate).
Key points regarding copper toxicity in broilers:
- 250 \text{ mg/kg}: This level is often cited as a cautionary point, as it has been shown to have negative effects on bird performance, such as depressed growth, reduced feed intake, and impaired feed efficiency, especially during the starter period. It can also cause gross lesions like oral lesions and gizzard erosion.
- 300 \text{ mg/kg}: Intake levels higher than this are generally related to subclinical or clinical toxicity.
- 500 \text{ mg/kg}: This level is consistently reported to significantly depress growth and feed conversion, cause severe oral lesions and gizzard erosion, and damage the morphology of the gastrointestinal tract (e.g., depressed villi height).
- Acute Poisoning: A single, very high dose of copper sulfate (CuSO$_4$) greater than 1 \text{ g} can be fatal.
Toxicity symptoms can include:
- Depressed growth and feed intake
- Poor feed conversion ratio (FCR)
- Severe oral lesions and gizzard erosion
- Damaged gastrointestinal tract morphology
- Accumulation of copper in the liver
- Watery diarrhea and listlessness (in acute cases)Copper (Cu) toxicity in broiler chickens is generally observed at levels of 250 \text{ mg/kg} of feed and above when provided as a supplement (e.g., cupric sulfate).

Excellent explanation — you’ve covered it perfectly. High density truly limits growth potential and overall flock performance.
-
Well said! Maintaining optimal space definitely helps improve welfare and ensures birds convert feed more efficiently.
-
Absolutely right — stress from overcrowding really shifts energy away from growth and impacts both health and FCR.
