  1. 1. NOVOgen Incubation Stéphane Hémon 03/2018
  2. 2. Key Points for Hatchery Management Rules
  3. 3. Incubation Keys points for Optimum chicks Quality  Hatching Eggs Management: Eggs Quality  Eggs storage Optimum conditions  Eggs disinfection - Eggs Pre heating  Incubation Parameters: Setters Management  Egg weight loss Management  Hatching Parameters  Hatching windows: Main target  Chicks quality Assessement  Chicks Dehydration  Hydrop Early feeding technology
  4. 4. Hatching Eggs Management Eggs Quality
  5. 5. Keep in Mind  No air cell when laid  As the egg cools it sucks in everything on the shell  Mostly bacteria and fungus will enter from the top of the egg.  Any substance on dirty hands will be sucked into the egg. Eggs Quality Main factor for chicks quality Characteristics of eggs
  6. 6. Embryo development start at ovulation Laid egg represents 1 days embryonic growth grade 10 (20,000 - 40,000 cells)
  7. 7.  Quality of the hatching egg depends on:  The sanitary status of the flock  Nesting material (Automatic vs manual nests)  Cleaning and disinfection (automatic nests)  Hygiene status of hatching eggs is determined in the first 3 minutes after lay. Quality of the hatching Egg
  8. 8. An Egg = A potential chick  Eggs must be collected as soon as possible after lay.  Clean nests are essential to prevent contamination of hatching eggs.  Eggs collection at least 4 times daily.Ideally 5 times (3 times morning and twice in the afternoon)  Eggs disinfection as soon as possible.  Wash and disinfect your hands regularly  Good Egg management is essential to avoid eggshell contamination and lost latter on during incubation.
  9. 9. Cuticle = Natural defences The shell is covered in bacteria, which enters very easily when the shell is still warm. Hygiene status of hatching eggs is determined in the first 3 minutes after lay.
  10. 10. Hatching egg management  Good Hatching Egg - 50g (depending of the hatchery) - Laid in a dry nest - Protected from dust - Free from feces and organic matter - Good shell = Solid shell
  11. 11. Egg abnormality non suitable for Incubation Broken shellCracks Shape Shell less Thin Shell Fragile Shell
  12. 12. Egg Quality Issues
  13. 13. Egg Storage Optimum conditions
  14. 14. Farms storage conditions Chick quality start at the farm As soon as possible after lay eggs are store in proper conditions. Clean place free of dust. Handling hatching eggs with care is crucial to keep optimum results. Proper storage condition is primordial: Temperature < 20°C and HR > 80% Fitting Not Fitting Room well ventilated with humidifier Poor ventilation no humidifier Egg directly on the floor
  15. 15. Constant environment conditions prior incubation is mandatory to achieve optimum hatchability. Excessive temperature fluctuation can lead to hatchability depletion of up to 3,5 % (variation of 2 F) Monitoring egg storage and transportation is necessary to ensure optimum hatching egg quality Egg storage temperature variation Impact Avoid temperature fluctuation = Main key for proper conditions.
  16. 16. Egg storage prior to Incubation
  17. 17. Minimum Requirements for optimum storage Conditions for Short storage:< 8 days HR 85% Temp 18 °C Conditions for Long storage > 9 days HR 90% Temp 12 °C If storage longer than a week turning eggs is necessary to reduce embryo mortality , minimum four times daily. Hatchability and Chicks vitality will be improved if eggs are turned during storage. Keep in Mind that Embryo develops at a temperature ranging from 21-to 23°C. Store eggs below < 20°C Storage temperature will depend on storage length, It can be useful to have two storage rooms.(one for short storage /one for long storage)
  18. 18. Storage conditions for optimal results Optimum conditions Period of storage 1-2 days 3-4 days 5-6 days 7-8 days 9-12 days 13-16 days 17-20 days Temperature 19.0°C (66.2°F) 17.0°C (62.6°F) 15.5°C (59.9°F) 14.0°C (57.2°F) 12.5°C (54.5°F) 12.0°C (53.6°F) 11.5°C (52.7°F) Relative Humidity (%) 70.0 80.0 85.0 90.0 90.0 90.0 90.0 Turning No No No Yes Yes Yes Yes

  21. 21. Eggs Disinfection
  22. 22. Eggs sanitizing: Disinfection  Egg disinfection As soon as possible after collection Before the air cell is formed. On selected egg ie good shell quality. Egg disinfection has a Major role in the prevention from contamination. It’s essential to do everything in order to assure the disinfection program.
  23. 23. Egg disinfection method  Fumigation => formalin  Spraying => quaternary ammonium, glutaraldehyde, hydrogen peroxide etc…  Egg washing: bath > 40°C, solution need to be change frequently.
  24. 24. Eggs sanitizing: Disinfection Formalin The most commonly used method. The Most efficient till now. Effective in reducing contamination over the surface of the shell. Fully effective in specific environmental conditions: Temperature > 24°C. Relative humidity >70%. Dosage: 21 grams of KMnO4 and 43 ml of formalin at 37.5% per m3. More effective if plastic or setter trays are used.
  25. 25. Egg Sanitizing: Disinfection Be aware over fumigation can be detrimental for embryo. Formalin dosage should be calculated according to room volume. Initial Disinfection: 1 m3 = 21g KMNO4+ 43 ML Formalin Ensuring a weekly setter disinfection in order to reduce bacteria level and to avoid setter contamination is recommended. Avoid freshly incubated eggs < 4 days. Dosage: 2L Formalin + 8L water evaporation in a plate. 10 ML/M3 Keep in mind: Conditions in Setters are perfect for bacteria development.(humidity and temperature).
  26. 26. Eggs Pre Heating
  27. 27. Hatchery - Incubation Pre heating Main Goal is to co-ordinate embryo development To reduce the hatch window and improve chick quality Pre heating at 88 F (31°C) for 5 hours is Common. Pre heating at 77 F (25 °C) for 8 to 12 hours between setters
  28. 28. Incubation Parameters Setters Management

  33. 33. Egg Weight loss Management
  34. 34. Egg weight loss management (EWLM) A good Egg weight loss management = Good chick quality A good monitoring is necessary to ensure a correct embryo development. Factors affecting WL: Ambient humidity/Egg weight/Eggshell quality Target to achieve at transfer (18 d) : 11 to 12% to optimize embryo development and chick quality. Optimum weight loss can only be achieved by managing humidity level during incubation. HR range from 80 to 86F according to egg weight loss.
  35. 35. 35 Air chamber size and humidity level in incubation Air chamber size is fluctuating according to humidity in setter. Adjustment of humidity level according to weight loss is crucial to reach optimum hatchability and chick quality. According to age flock shell conductance will change.
  36. 36. Water loss effects on hatchability and chick quality 36  Water loss too low: < 11% small air chamber Hatching difficulties Head oedema Red hocks Thick belly Unhealed navel High percentage of DIS

  43. 43. Hatching Windows
  44. 44. What is the Hatch window: Time span between the hatching of the first chick and the last chick after the eggs transferred into the hatcher. What do we want to reach: Target 20h before chick pulling: 20% of chicks hatched maximum 12h before chick pulling: 80% of chicks hatched maximum Improvement and management of the hatching windows: the key points
  45. 45. Target to achieve 20 80 100 0 20 40 60 80 100 120 20H 12H 0H %Hatched Hours before Pull Hatch window target %Hatched
  46. 46. The Hatch Window influence of the air flow Uniform air flow = optimum condition all egg at 100 F (range 99,5-100,5F) Narrow hatch window Good hatchability and optimum chick quality Air flow fluctuations = EST fluctuations  Wide hatch window Hatchability and chick quality affected
  47. 47. Key factors affecting the hatch window Similar egg Characteristics and embryo development at setting is crucial Uniformity of conditions in setter/hatcher Equipment design, incubation profile Monitoring the hatching window is a way to ensure that all the processes are optimum to achieve delivery of good chick quality. The hatching window is the real indicator of all the processes from the time of oviposition.
  48. 48. Impact of the hatch window on Chick quality The hatch window is affecting chick uniformity: If wide > 30h : uniformity of chicks will be affected If Narrow: Optimum chick uniformity If the hatch window is too wide: part of the chick will be dehydrated and flock uniformity will be affected.

  51. 51. Chick quality Assessment
  52. 52. What factors affect chick quality? Breeder flock source Age, disease status Egg handling ,On the farm, in transit, and in the hatchery Hatchery Management, sanitation and equipment maintenance Chick processing and delivery Brooding management
  53. 53. Quality control
  54. 54. First grade chicks Weight: average of 40 g, 67-68 % of the initial egg weight Activity must be good (will come back on its legs quickly if on his back) Down must be clean and dry Abdomen must be soft and normal size Eyes open. Legs normal balance Umbilicus: well closed and dry No residual membrane No residual egg yolk
  55. 55. Monitoring chick yield Average chick weight/ Average egg weight  Counting/weighing first grade chicks to calculate average chick weight  Average eggs weight from a tray. Target for best chick quality is 67-68 % Egg weight lost 11 to 12% Adjustment of the setting hours can be done If 66% Eggs setting must be set 3h later < 67% 67-68% >68% Hatched In advance Good activity Just hatched Temperature too high Optimum chicks quality Temperature too low HR too low HR too high Risk of Dehydratation Noisy Chicks Actif Less actif
  56. 56. Chick Quality Issues = Improper conditions Navel issues are related to setter/Hatcher management HH-CT = high humidity cold temperature LH-HT = low humidity hot temperature HH-CT issues LH-HT issues LH-HT issues HH-CT issues LH-HT issuesLH-HT issues
  57. 57. Navel Examination Navel Examination should be performed after hatched to detect any failure in the incubation or Hatching Process High percentage of Second grade chicks is mainly due to setters/hatchers failure. Setters and hatchers Maintenance is primordial to reach good performance.
  58. 58. What causes dehydration? Hatchery Issues Incorrect pull times from the hatchers. Chicks are in the hatchers too long. Young breeder flocks are more prone to dehydration. Hot spots – machine maintenance issues and ventilation issues Overheating chicks in the hatcher, hallways or chick room. Improper chicks holding area conditions Chicks dehydration
  59. 59. Panting Chicks (heat stress) Must be avoid Panting Chicks: must be avoid, will affect mortality rate and body weight at 7 and 10 days Keep in mind that keeping chicks too long at high temperatures is affecting the growth. Narrow hatching windows Necessary to avoid chicks dehydration and to keep a good uniformity Chick pulling Management Remove chicks as soon as possible from the Hatcher Chick in optimum conditions (Rectal temp 104/105F) are losing 1 to 2 g/24h.Should be maintained until delivery (40 to 40,6°C) Chick in non optimum conditions (Rectal temp >106F) are losing 5 to 10g/24h (more than 15 % of its body weight)
