19 Jun Egg production drop caused by stress
Posted at 20:45h in Layers and breeders
Stress is a very common cause of laying problems. Hens are animals of habit and any change (related to management, feed, environment, etc) unsettles them, resulting in negative effects in their wellbeing and productivity. Hen’s response to stress can be categorized in five groups:
- Morphological changes: Livability and body condition are influenced by environmental conditions (temperature, caging system). Such factors also affect internal organs like liver status, bone resistance to breakage and adrenal glands.
- Endocrinal and blood changes: Decreased Ca2+ ions in blood, water and sodium retention.
- Digestion: Stress may induce reduction of feed intake, worse feed use and metabolic changes in digestive system that favor the onset of infections.
- Immunity: immune system is depressed, showing fewer circulating lymphocytes and less antibody response.
- Reproduction: Reproduction in hens was negatively affected by stress, as measured by cessation or reduction of laying, atrophic follicles, and decreased oviduct weight. Egg quality is also affected, producing a higher percentage of defective eggs (cracked, weak or dirty).
