Farm site selection is fundamental to successful poultry farming. The site should be elevated, dry, and well-drained with groundwater level below 2 meters. It must be at least 500m from residential areas, 1000m from major roads, and 3000m from other farms and slaughterhouses. Water sources must be abundant and meet national drinking water standards, with reliable electricity supply.

Chicken house construction should follow all-in-all-out principles. Environmentally controlled houses use negative pressure longitudinal ventilation, cooling pads, and automatic lighting systems to effectively control the microclimate. Floor density for broilers is 8-12 birds/m2, slatted floor 12-16/m2, and cages 20-30/m2. Layer cages provide approximately 400-500 cm2 per bird.

Duck house design must consider the aquatic nature of waterfowl. Ideal sites should be near natural water bodies or equipped with artificial ponds. Floors should have a 1%-2% slope for drainage with dry, loose litter. Goose housing can be simpler, though brooding houses need good insulation. Exercise yards should be 2-3 times the indoor area with shade shelters for hot seasons.

Geese are classified as large, medium, and small types. Large breeds like Shitou goose reach 10-12 kg for adult males. Medium breeds like Wanxi White, Zhedong White, and Sichuan White weigh 5-7 kg and produce 30-50 eggs annually. Small breeds like Taihu, Huoyan, and Wulong geese have superior reproductive performance at 60-100 eggs per year, serving as important genetic resources.

Incubation technology is crucial in the poultry industry chain. Modern farms universally adopt artificial incubation. Chicken incubation takes 21 days, ducks 28 days, and geese 30-31 days. For chickens: days 1-18 at 37.8C with 55%-60% humidity; days 19-21 after transfer at 37.2C with 70%-75% humidity. Duck and goose incubation requires slightly higher early temperatures and higher late-stage humidity.

As environmental regulations tighten, treatment and resource utilization of livestock waste has become critical. Poultry manure contains rich organic matter and NPK nutrients. Each layer produces 40-50 kg of fresh manure annually. After composting treatment, a 10,000-bird layer farm can produce 200-250 tons of organic fertilizer worth approximately 100,000-150,000 yuan.

Nutritional regulation during peak laying is critical. Hens producing above 90% need daily intake of 18-20g crude protein, 4.0-4.5g calcium, and 350-380mg available phosphorus. Supplementation with 0.1%-0.2% methionine and 0.05%-0.1% lysine significantly improves egg weight and production. Vitamins C and E play important roles in stress resistance.

Goose farming profitability varies by model and breed. Commercial geese take 70-90 days reaching 4-6 kg, with 3-4 batches possible annually in southern regions. Production cost is 45-55 yuan per bird including 10-15 yuan for goslings and 25-30 yuan for feed. Common white geese sell at 16-20 yuan/kg while premium breeds like Shitou reach 25-30 yuan/kg.

Medication plays a supporting role in disease control. Antibiotics for bacterial diseases should be selected based on sensitivity testing to avoid resistance. Coccidiosis control uses rotation or shuttle programs. Chinese herbs like Coptis, Scutellaria, Isatis, and Astragalus polysaccharides effectively boost immunity as antibiotic alternatives.
