Group of laying hens daily observation five-character policy

July 16, 2025

Daily observation is a critical component in the feeding and management of laying hens. By carefully observing the flock on a daily basis, farmers can gain a clear understanding of the overall health and performance of the birds. This practice allows for early detection of issues, enabling timely interventions that can reduce feed costs and improve economic returns. Over more than a decade of hands-on experience, I have developed a five-step approach to daily observation, known as the "See, Hear, Touch, Check, Decide" method. 1. **See** – Observing key indicators such as feed intake, water consumption, egg production, feces, and the general behavior and appearance of the hens helps identify any underlying problems. - **Feed and Water Intake**: Healthy, high-producing hens usually eat vigorously. The ratio of feed to water should be around 1:2 to 2.5. A sudden increase in feed intake may signal rising egg production, while a decrease could indicate illness or a drop in productivity. - **Egg Production**: Monitoring egg weight, laying rate, and shell quality is essential. Egg weight should gradually increase until about 35 weeks of age, after which it stabilizes. A decline in egg size might point to dietary issues. Egg production typically peaks between 28–32 weeks (over 96%) and then declines slowly. Abnormal drops should be investigated for disease or management issues. Shell quality must be consistent, with no cracks or discoloration, which could result from disease, diet, or stress. - **Feces**: Normal droppings are soft, gray-brown, with a small amount of white urate on top and no strong odor. Changes in color, texture, or smell may indicate dietary imbalances, illness, or environmental factors. - **Mental State and Appearance**: Healthy hens are active, alert, and responsive. Their eyes are bright and centered, their beaks are aligned, and their combs are red and plump. Any signs of lethargy, poor posture, or dullness may suggest illness or low productivity. 2. **Hear** – Listening to the flock’s sounds, especially at night when they are quiet, can reveal hidden issues. - **Respiratory Sounds**: Normal hens should make little to no noise. Snoring, coughing, or sneezing may indicate respiratory infections. - **Abnormal Calls**: Unusual noises during the day or sudden deaths at night could point to heat stress, poor ventilation, or other health concerns. In some cases, hens may suffer from egg-binding, where hard-shelled eggs become stuck in the oviduct. - **Pest Activity**: In areas with security risks, checking for pests or intruders is important to prevent losses. 3. **Touch** – Physically examining individual hens can provide further insights. - Randomly selecting hens from the cage and checking their body temperature, weight, chest, abdomen, and pubic space helps detect abnormalities. Also, checking for injuries to the vent or legs is crucial. 4. **Check** – After observing and touching, it's important to analyze the findings thoroughly. If necessary, laboratory tests should be conducted to confirm diagnoses. 5. **Decide** – Based on the observations and analysis, an action plan must be made. The measures taken should be timely, accurate, and comprehensive to ensure effective results. In conclusion, while many factors influence the performance of laying hens, daily observation should never be overlooked. When done consistently, it allows for early problem identification, better management decisions, and improved profitability. It also helps farmers build valuable experience over time, leading to more efficient and sustainable poultry farming.

Hydrogen Gas Generator Inhaler

What's hydrogen gas inhaltor? Let's to know more.

The development of hydrogen gas inhalation therapy

The research on hydrogen in the field of biology can be traced back to the beginning of the 21st century. That said, hydrogen inhalation therapy is an emerging treatment method that has received a lot of attention.

In 2007, Japanese scholar Professor Shigeo Ohta reported for the first time in the journal Nature Medicine that hydrogen has a significant therapeutic effect on cerebral ischemia-reperfusion injury. Since then, more and more studies have shown that hydrogen has various biological effects such as antioxidant, anti-inflammatory, and anti-apoptosis, and has potential therapeutic value for a variety of diseases.

How does hydrogen gas work?

The hydrogen gas generator uses water electrolysis to gather hydrogen gas and oxygen gas, and the ratio is H2:O2=2:1. Hydrogen exists in nature as a diatomic molecule. It is the molecule with the smallest weight and volume in nature, and is the only substance known in nature that can selectively scavenge free radicals.

The mechanism by which it exerts its antioxidant response mainly includes the following aspects:

1. Unique antioxidant properties

1) Selective antioxidant: Hydrogen can selectively neutralize the most toxic hydroxyl radicals (·OH) and nitrite anions (ONOO-), while reactive oxygen species with physiological functions such as superoxide anions (O₂⁻) , hydrogen peroxide (Hâ‚‚Oâ‚‚), etc. have less impact. This allows hydrogen to resist oxidation without interfering with normal physiological redox reactions.

2) High diffusivity: Hydrogen is the smallest molecule in nature and has extremely high diffusivity. It can quickly penetrate biological membranes and reach various parts of cells, including mitochondria, cell nuclei, etc., effectively remove free radicals and protect cells from oxidative damage.

2. Regulation of oxidative stress-related signaling pathways

1) Activate the Nrf2 signaling pathway: Nrf2 (nuclear factor E2-related factor 2) is an important antioxidant transcription factor in cells. Hydrogen can activate the Nrf2 signaling pathway, promote the expression of downstream antioxidant enzymes such as superoxide dismutase (SOD), glutathione peroxidase (GPx), etc., and enhance the cell's own antioxidant capacity.

2) Inhibit the NF-κB signaling pathway: NF-κB (nuclear factor κB) is a key inflammatory signaling pathway that is activated under oxidative stress, leading to the release of inflammatory factors. Hydrogen can inhibit the activation of NF-κB and reduce the inflammatory response, thereby reducing the damage to cells caused by oxidative stress.

3. Improve mitochondrial function

1) Reduce mitochondrial free radical production: Mitochondria are the main place where energy is produced in cells and are also the main site where free radicals are produced. Oxidative stress can lead to mitochondrial dysfunction and increased free radical production. Hydrogen can improve mitochondrial function and reduce the production of mitochondrial free radicals, thereby alleviating oxidative stress.

2) Maintain the stability of mitochondrial membrane potential: Hydrogen can maintain the stability of mitochondrial membrane potential, prevent the opening of mitochondrial membrane permeability transition pores, reduce the release of cytochrome C, and inhibit cell apoptosis.

4. Regulate intestinal flora

1) The relationship between intestinal flora and oxidative stress: The imbalance of intestinal flora is closely related to oxidative stress. Unhealthy intestinal flora will produce a large number of harmful metabolites, such as endotoxins, hydrogen sulfide, etc., which can cause oxidative stress and inflammatory reactions.

2) The regulating effect of hydrogen on intestinal flora: Hydrogen can regulate the composition and function of intestinal flora, increase the number of beneficial bacteria and reduce the growth of harmful bacteria. Beneficial intestinal flora can produce substances such as short-chain fatty acids, which have antioxidant and anti-inflammatory effects, thereby reducing the damage of oxidative stress to the body.

Why choose hydrogen gas inhalation therapy?

• High safety: Hydrogen is a colorless, odorless, non-toxic gas with no obvious toxic or side effects on the human body.

• Strong antioxidant effect: Hydrogen can selectively neutralize toxic free radicals such as hydroxyl radicals and nitrite anions, reducing oxidative stress damage.

• Significant anti-inflammatory effect: Hydrogen can inhibit the release of inflammatory factors and reduce inflammatory reactions.
