Insights
Poor nutrition and suboptimal environmental conditions in broiler production lead to high chick morbidity and mortality. Addressing these factors is crucial for improving chick survival rates and overall flock health.
Area of Science:
- Poultry Science
- Animal Husbandry
- Veterinary Medicine
Context:
- Investigations conducted on breeding eggs, chick embryos, newly hatched birds, and habitats within two broiler dressing combines.
- Focus on identifying root causes of early-life chick morbidity and mortality in commercial broiler operations.
Purpose:
- To determine the primary factors contributing to high chick morbidity and mortality during the initial days post-hatching.
- To analyze the impact of egg quality, biosecurity, nutrition, and environmental conditions on chick survival.
Summary:
- Lower biologic value of hatching eggs due to deficient breeder feeding.
- Non-compliance with veterinary, sanitary, and hygiene standards throughout egg production, transport, storage, and incubation.
- Inadequate feed mixtures and other nutritional deficiencies in newly hatched chicks.
- Suboptimal environmental conditions, specifically low temperatures and relative humidity, during the early rearing period.
Impact:
- Highlights critical deficiencies in broiler production chain impacting chick viability.
- Provides actionable insights for improving broiler chick survival through enhanced nutrition and environmental management.
- Emphasizes the importance of stringent adherence to biosecurity and hygiene protocols in poultry farming.
Abstract:
Scientific and productional experiments and complex investigations were carried out on breeding eggs, chick embryos, newly hatched birds, and ecologic habitats of two broiler dressing combines. It was found that the basic reasons for the morbidity and mortality of chicks in the first days following hatching were: the eggs chosen for hatching were of a lower biologic value due to deficient feeding (1); the veterinary, sanitary, and hygiene requirements with regard to the production, shipping, storing, and hatching of breeding eggs were overlooked (2); the little birds were offered feed mixtures of low value, along with admission of other drawback in their feeding (3); during the first days of raising the birds were kept at lower temperatures and lower relative humidity on the premises.
