Monitor nutrient levels: Regularly check and adjust nutrient levels to ensure optimal growth.
Control temperature and humidity: Maintain a stable environment with suitable temperature and humidity levels for optimal growth.
Prevent mold and pests: Keep the growing area clean and well-ventilated to prevent mold and pest infestations.
Harvest at the right time: Harvest the hydroponic grass at the peak of its nutritional value for the best results.
Fodder Tray |
The bottom has holes to allow water and nutrients to flow, avoiding water accumulation, and it is easy to manage. |
Spraying System |
Timed spraying irrigation can provide adequate water, and promote green fodder growth. |
Humidifier |
Humidity is one of the most important external factors during the seed germination process. Low humidity results in low germination rates, while high humidity can cause seedlings to become diseased. |
Temperature Control Device |
(Such as air conditioning) Temperature is also important for sprouting. If the temp lower, the seeds will not germinate, while being too high can result in mold and odor. |
Hydroponic Growing Racks |
It’s the hydroponic vertical growing system, a corrosion-resistant and rust-proof is needed, and the size should be suitable for fodder trays. |
LED Growing Light |
Do not excessively pursue light intensity, as strong light can burn the seedlings. Provided that the light intensity is sufficient. |
Seed Soaking Equipment |
(optional) Including mesh bags, seed soaking boxes, ozone sterilization equipment, liquid temp control system, and a darkroom. These devices can help improve germination rates and reduce the impact of pathogenic bacteria. |
Water Circulation System |
(optional) Indoor hydroponic fodder production generally comes with a water circulation system, but it’s not necessary for container farms. |
Hydroponic grass offers various benefits as livestock feed, including direct feeding, drying and crushing for feed, or inclusion in mixed feed. It's suitable for a range of animals, including cows, sheep, horses, pigs, chickens, ducks, and others.
**Hydroponic Grass for Cows:**
Hydroponic green feed can increase milk fat and protein content in cows. Fresh feed can also improve their mood and health.
**Fodder Systems for Beef Cattle:**
Beef cattle typically need high-fiber feed, but hydroponic grass has relatively low fiber content. Mixing it with other roughage is recommended to improve meat quality and nutritional value.
**Hydroponic Fodder for Goats:**
Green feed can enhance meat and fur quality in sheep. They can subsist solely on green feed, addressing basic livestock food needs.
**Hydroponic Fodder for Chicken:**
Hydroponic grass can boost protein content and nutritional value, while reducing cholesterol in chicken meat.
**Feeding Recommendations:**
Different animals require varied ratios of hydroponic green forage based on nutritional needs, feeding methods, and market demands. For example, confined sheep need ample protein and energy for rapid growth and muscle development, while free-range dairy cows need fiber and protein for milk production and digestive health.
**Green Feed For Cattle:**
As ruminants, cattle need plenty of roughage for rumen fermentation. Since hydroponic fodder has low roughage content, cattle should be given hay and straw alongside hydroponic green feed. They also require high-energy, high-protein feeds like corn and soybean meal to meet energy and protein needs. Cows primarily rely on grass as their main feed, using hydroponic green feed as a supplement.
**Green Fodder For Goats Or Sheep:**
Their rumen differs from cows and emphasizes balancing the microbial community. They need more roughage and water, so the amount of hydroponic green feed can be increased. Since sheep have weaker digestion and absorption abilities for high-energy, high-protein feeds, they need high-quality roughage like alfalfa to balance nutritional needs. They can consume a higher proportion of hydroponic green grass, supplemented with nutrient-rich trees and shrubs like leaves and branches for necessary fiber, protein, and energy.
Hydroponic green fodder is a nutritious and cost-effective feed option for livestock. However, like any agricultural practice, it comes with its own set of challenges. Here are some common problems encountered in hydroponic green fodder production and their solutions:
Mold and Fungal Growth: Mold and fungal growth can occur due to high humidity or inadequate ventilation. To prevent this, ensure proper air circulation and maintain optimal humidity levels (around 50-70%).
Nutrient Deficiencies: Nutrient deficiencies can arise if the nutrient solution is not properly balanced. Monitor the pH and nutrient levels regularly and adjust as needed. Use a balanced hydroponic nutrient solution suitable for green fodder.
Algae Growth: Algae growth can occur if the system is exposed to light. Keep the growing area dark or use opaque materials to cover the system. Additionally, regular cleaning and maintenance can help prevent algae buildup.
Pests and Diseases: Pests and diseases can affect hydroponic green fodder. Use pest-resistant varieties, maintain proper hygiene, and regularly inspect plants for signs of pests or diseases. Use organic pesticides or fungicides if necessary.
Temperature Fluctuations: Fluctuations in temperature can stress the plants and affect growth. Maintain a stable temperature within the optimal range for green fodder (around 18-25°C or 64-77°F). Use shade cloth or insulation to protect the plants from extreme temperatures.
Water Quality: Poor water quality can lead to nutrient imbalances and plant health issues. Use clean, filtered water and regularly test the water for pH and nutrient levels. Use a water treatment system if necessary.
Overcrowding: Overcrowding can lead to competition for nutrients and space, affecting the growth of the fodder. Ensure proper spacing between trays or growing containers and avoid overcrowding.
Harvesting Timing: Harvesting the green fodder at the right time is crucial for maximum nutrient content. Harvest when the fodder is young and tender, usually around 7-10 days after sowing.
Hydroponic fodder production utilizes spray irrigation and circulating water technology for cultivation, achieving intelligent and automated control through temperature, humidity, and nutrient irrigation.
The system maintains a constant temperature between 20-23 degrees Celsius and automatically drips or sprays every 6-8 hours, maintaining a humidity range of 60-70% in the growing space.
In this environment, hydroponic fodder can be produced within 7 days from grains to fresh green feed, and each kilogram of grain can grow into 6-8 kilograms of fresh grass, which can replace more than 20% of concentrate feed and hay compared to traditional grain and other feed materials, greatly reducing feed costs.
There are two common types of hydroponic fodder systems:
Indoor Hydroponic Fodder System:
The indoor hydroponic fodder system is a vertical farming system suitable for any scale, also known as hydroponic pasture.
It mainly involves building hydroponic fodder growing racks indoors, and then selecting various auxiliary equipment such as water pumps, water circulation systems, irrigation systems, and intelligent control terminals according to the actual scale.
The fodder system can be flexibly customized to meet the needs of family farming or commercial large-scale green fodder planting.
Advantages:
High flexibility, able to provide green feed for family or commercial farming. It can greatly increase the yield of green fodder while reducing the comprehensive cost.
