Breaking: Expert Guidance Reveals Critical Harvest Timing for Superior Livestock Feed
August 17, 2025 – Livestock farmers can significantly enhance feed quality and, consequently, animal health by precisely timing the harvest of crucial summer forage crops like foxtail millet. New findings from the National Institute of Livestock Science offer actionable insights into optimizing protein and fiber content, directly impacting the nutritional value of animal feed.
The Science of Optimal Forage Harvest
The National Institute of Livestock Science has announced groundbreaking research detailing how the stage of growth at harvest directly influences the nutritional profile of foxtail millet, a vital summer feed crop frequently enough cultivated in flood-prone rice fields. this comprehensive study provides farmers with evidence-based strategies for harvesting, processing, and storing forage to maximize its benefit.
Foxtail millet thrives in warm, humid conditions, but its nutritional composition changes dynamically as it grows. While increased height correlates with higher yields, it also leads to a decrease in protein and an increase in fiber, altering its overall feed value.
Key findings highlight a crucial window for harvesting: when foxtail millet is cut at approximately 70 cm,it exhibits its highest crude protein content,reaching up to 21.1%. This is a marked difference from harvesting at later stages, such as when the plant reaches about 160 cm, where crude protein can drop to 9.7%. Further maturity, indicated by the emergence of seeds, reduces protein to 6.9%. Concurrently, fiber content escalates from 29.7% to 36.5% as the plant matures.
| Harvest Stage (Approx. Height) | Crude Protein (%) | Fiber Content (%) |
|---|---|---|
| 70 cm | 21.1 | 29.7 |
| 160 cm | 9.7 | 30.0+ |
| Seeding Stage | 6.9 | 36.5 |
Strategies for High-Quality Feed Production
for farmers aiming for superior feed quality, the advice is clear: harvest foxtail millet before the onset of flowering. Following harvest, the crop should be meticulously dried for about 45 days to produce high-quality hay or silage. This process preserves the valuable protein content and minimizes fiber, ensuring optimal nutrition for livestock.
Alternatively, farmers prioritizing yield over immediate protein content can opt for later harvests. in such cases, enhancing fermentation quality and storage viability can be achieved through careful moisture management (40-50%) and a fermentation period of around 23 days, often aided by lactic acid bacteria cultures.
Evergreen Insights for Sustainable Livestock Farming
The insights provided by the National Institute of Livestock Science underscore a fundamental principle in animal husbandry: the quality of feed directly dictates animal health and productivity. Understanding the growth cycle and nutritional changes of forage crops allows farmers to make informed decisions, leading to more efficient and sustainable farming practices.
This research aligns with broader trends in agriculture, emphasizing precision farming and data-driven decision-making. By leveraging such scientific guidance, farmers can not only improve their livestock’s diet but also perhaps reduce reliance on expensive commercial feed supplements. Ensuring consistent access to high-quality forage is a cornerstone of resilient livestock operations.
The availability of comprehensive guides, such as the ‘Feed Cultivation Technology Guide’ distributed by the institute, empowers farmers with the knowledge to tailor their forage management strategies to specific farm goals and environmental conditions. This proactive approach contributes to the overall well-being of the animals and the economic viability of the farm.

Frequently Asked questions
What is the optimal harvest time for foxtail millet to maximize protein content for livestock feed?
Forage crops like foxtail millet should be harvested when approximately 70 cm tall to achieve the highest crude protein content, which can reach 21.1%.
How does harvesting foxtail millet later in its growth cycle affect its nutritional value?
Harvesting foxtail millet at later stages, such as when it reaches about 160 cm or begins to seed, results in decreased protein content (down to 9.7% or 6.9%) and increased fiber content (rising from 29.7% to 36.5%).
What are the recommended methods for processing foxtail millet into high-quality feed?
To produce high-quality feed, farmers are advised to harvest foxtail millet before it fully matures and then dry it for 45 days to create hay or silage.
How can farmers prioritize yield when harvesting foxtail millet for feed?
If the primary goal is maximizing yield, foxtail millet can be harvested after it has matured. To enhance fermentation quality and storage, it’s recommended to adjust moisture content to 40-50% and allow for 23 days of lactic acid fermentation.
What guidance is available for livestock farmers on foxtail millet cultivation and harvesting?
The National Institute of Livestock Sciences has developed a ‘Feed Cultivation Technology Guide’ that offers detailed recommendations on optimal harvesting, drying, and ensiling techniques tailored to different feed objectives.
