Nutritional specifications across layer life stages: chick starter (20% CP), pullet grower, pre-lay calcium loading (2.5% Ca), and peak production mash (3.8-4.2% Ca).
Evaluate non-feed withdrawal molting for laying hens: low-sodium diets, high-fiber mash, post-molt eggshell strength, and economic viability at 65-70 weeks.
Safe aerial disinfection while birds are in the house: non-irritant biocides, droplet size selection (50-80 microns), respiratory relief, and virus reduction.
Keep broiler litter at optimal 20-25% moisture: drinking nipple pressure calibration, minimum ventilation moisture removal, and preventing footpad dermatitis.
Target brooding temperature schedule: starting at 33-35°C on Day 1, decreasing 3°C per week down to 21°C at Week 5, and interpreting chick behavior.
Calculate the true financial cost of heat stress: mortality spikes, drop in egg production, reduced broiler ADG, and the ROI of installing tunnel cooling.
