| Term | Definition |
|---|---|
| Digestive System Components | -beak/mouth, crop, proventriculus, gizzard, small and large intestine, cloaca. |
| Reproductive System Components | -ovary (yolk), infundibulum, magnum (egg white), isthmus (keratin shell), vagina, cloaca. |
| Commercial Egg Producer Qualities | -egg numbers, eggshell quality, egg size, fertility, hatchability. |
| Broiler Producer Qualities | -evaluate same as egg producers and the carcass quality. |
| Turkeys | very large birds that have predominantly white meat. |
| Ducks | birds harvested @7-8 weeks of age, their darker meat has a Gamey taste and clean. |
| Geese | birds that are evaluated on their carcass size, growth, feather coat, and mortality. |
| Chicken Repro. Data | repro: puberty is managed to occur at 20-22 weeks using the light cycle. Eggs are incubated for 21 days |
| Turkey Repro. Data | repro: puberty occurs a 30 weeks, hens are bred by AI (toms are too large) Eggs are incubated for 28 days |
| Duck Incubation | 28 days |
| Goose Incubation | 28-34 days |
| Egg Incubation Temperature | should be kept at 99.5-100*F air incubator, temp is the most important aspect, eggs should be warmer in first 4 days and cooler in last 3 days. |
| Incubation Humidity | should be kept at 60-65% throughout incubation then increase to 70% during last few days. |
| Incubation Egg Position | the large end should be up (air cell) or horizontal, small end up can cause embryo death. |
| How many times do you turn the eggs a day? | 5 times per day |
| Incubation Oxygen | should be kept at 21 for optimum development, elevated carbon dioxide levels reduce hatchability. |
| Candling Eggs | shine light through and see if the embryo is developing and remove dead eggs. |
| Feeding | most require only 2.8 lbs of feed per every pound of weight gain |
| Managing Young | -clean/disinfect -use litter to absorb wastes -adequate floor space and a feeding area -lighting for function -debeaking |
| De-beaking | a common procedure for layers, performed at 7-10 days, do not trim ill birds. Prevents: feather plucking, fighting, and cannibalism in intensive housing. |
| Managing 10-20 week olds | -floor space (needed for scratching, seeking, pecking) -full feed of grower formula -clean water |
| Managing Layers (Hen housing) | layers need 1.5-3.5 sq ft of floor space per bird, litter, medicated water system if needed, balanced ground ration. Egg producers are caged with 6-10 birds with egg gathering systems. |
| Nutritional Deficiencies | -protein and amino acid -calcium, phosphorus, manganese, vitamin D -iron and copper -selenium |
| Other Diseases | -endo and ecto parasites -bacteria and viruses -avian influenza H5N1 flu strain that is zoonotic |
| Vaccinations against: | -New Castle Disease, Bronchitis, Coccidiosis, Marek's Disease |
| Avian Influenza (Bird Flu) | disease spread by migrating waterfowl to small and large poultry flocks, vaccine reduces CS's/viral shedding/death. Not all types approved in USA, and some must be approved by state veterinarian. |
