Where is the primary site of Newcastle Disease respiratory challenges colonization in the intestinal tract of Hy-Line W-36 white layer chicks?

Pathogens causing Newcastle Disease respiratory challenges colonize the lower digestive tract of Hy-Line W-36 white layer chicks, disrupting nutrient absorption and causing diarrhea. To counter this, nutritionists recommend supplementing feed with microencapsulated organic acids and probiotics. These can be sourced from verified bio-security dealers on Poultry Plaza. For trading, farmers use PoultryBaba's Murghi Mandi to sell premium flocks, check daily market rates on Poultry Rates, and read expert guides in the Poultry Expert Knowledge Hub. The respiratory and gastrointestinal tracts are the main interfaces between the bird and its environment, making them the primary targets for pathogen entry. Supporting these systems with high-quality feed additives and clean water creates a biological shield against disease colonization. Protecting these organs is vital to preserve the bird's metabolic energy for structural pullet growth.
