Effective approaches to stress prevention in poultry

Modern poultry farming plays an important role in agriculture by supplying meat and eggs. However, high productivity is often accompanied by stress factors that affect bird health and product quality. Stress causes dehydration and electrolyte imbalance, promotes oxidative processes and suppresses immunity, reducing productivity and increasing production costs.

Detailed analysis shows the potential scale of these losses. Under stress, laying hens can experience a 10–30% reduction in egg production and a 5–7% reduction in egg weight. Shell structure also deteriorates, and the proportion of misshapen eggs may reach 10%. In broilers, the effects include a 10–15% reduction in liveweight gain and poorer meat quality. Worldwide, annual economic losses associated with poultry stress amount to billions of dollars. These figures highlight the need to develop and implement effective preventive measures on competitive poultry farms.

Research has identified several main measures for protecting poultry against stress:

1. Optimise housing conditions. This includes modern climate-control technologies, appropriate stocking density and lighting programmes adapted to birds' physiological needs.
2. Train staff. Regular training in bird handling can substantially reduce stress caused by routine management procedures.
3. Provide appropriate nutrition. Balanced compound feed with a suitable pellet size and a consistent feeding schedule form the foundation of prevention.

Specialised poultry feed additives also have an important role. Probiotics and phytobiotics have become increasingly popular because of their effectiveness in improving resilience to adverse conditions.

Balancing diets with premixes remains important, but this is often insufficient under intensive commercial poultry production. Premixes cover basic vitamin and mineral requirements for maintenance and standard productivity. Expressing high genetic potential places additional demands on the bird, sharply increasing vitamin requirements. Vitamins are essential to the antioxidant system, which is the first line of defence during stress.

The following vitamins are particularly important in preventing and reducing stress effects:

• Vitamin A supports epithelial tissue health and immune function.
• Vitamin D3 helps correct mineral imbalances and strengthen bones and eggshells.
• Vitamin E neutralises oxidants, reduces tissue damage and supports metabolism.
• B vitamins—B1, B2, B3, B5, B6, B9 and B12—support functions ranging from the nervous system and energy metabolism to immunity and antioxidant activity.
• Vitamin C is a powerful antioxidant involved in regulating cortisol levels.
• Vitamin K3 participates in neurotransmitter formation and the inhibition of oxidative stress.

International research supports additional vitamin supplementation above standard requirements as a way to reduce the negative effects of oxidative stress.

The form in which vitamins enter the body is as important as their composition. Scientific evidence indicates that liquid feed additives are utilised more efficiently than solid forms because of greater bioavailability and faster absorption of active components.

AquaVit Combi was developed as a liquid vitamin complex for laying hens and other poultry. Its vitamins are selected to work together at the cellular level, providing integrated support against the consequences of stress in commercial poultry production.

The product has a balanced formulation containing a broad range of vitamins and essential amino acids:

• Vitamin A: 20,000,000 IU/L
• Vitamin D3: 4,500,000 IU/L
• Vitamin E: 9,000 mg/L
• B vitamins—B1, B2, B3, B5, B6, B9 and B12—at appropriate levels
• Vitamin C: 50,000 mg/L
• Vitamin K3: 4,500 mg/L
• Amino acid complex: 59,960 mg/L

Production trials using the additive at 0.2–1.0 L per tonne of water showed improved performance in laying hens, broiler chickens and replacement pullets, together with better metabolic function.

Poultry feed additives such as AquaVit Combi address several practical needs:

• Meeting young birds' vitamin and amino acid requirements during critical growth periods;
• Normalising metabolism during vitamin deficiencies and unbalanced feeding;
• Improving the effectiveness of veterinary interventions;
• Reducing the adverse effects of antibiotics and coccidiostats.

Stress prevention is an important part of efficient, sustainable poultry production. An integrated approach combining better housing conditions with appropriate use of modern feed additives can substantially reduce the effects of stress. Products developed specifically for laying hens help maintain high productivity and minimise economic losses. Attention to bird health and welfare ultimately determines the profitability of the whole business.
