For months, excessive and continuous rainfall has shaped the agricultural landscape, disrupting farming practices and crop yields. This weather pattern, far from being without consequences, has particularly affected the quality of forage — a key component in livestock nutrition.
Understanding the issue
Forage crops are harvested to feed livestock and play a crucial role in milk and meat production.
The quality of this forage depends on many factors, with climate being one of the most decisive.
While moderate rainfall promotes the growth of forage plants, excessive rain causes several issues.
-
Excess Moisture and Rot:
Continuous rainfall maintains high humidity levels in soils and plants, promoting the development of moulds and fungal diseases.
Contaminated forage can become toxic for livestock, leading to health problems and reduced production.
-
Reduced Nutritional Value:
Excess water can dilute essential nutrients within the plants, such as proteins and minerals.
In addition, prolonged wet conditions may cause nutrient leaching from the soil, further lowering the overall nutritional quality of the harvested forage.
-
Harvesting and Storage Difficulties:
Waterlogged soils make mechanical harvesting more difficult, increasing the risk of soil compaction and crop damage.
Moreover, high moisture levels complicate the drying process, which is essential for proper preservation.
Poorly dried forage is likely to ferment or develop mould during storage.
-
Silage Fermentation Issues:
Silage — a fermented forage used for livestock feed — requires specific conditions to ferment properly.
Excess water disrupts this balance, resulting in poor fermentation and a decline in the nutritional quality of the silage produced.
Consequences for livestock farmers
For livestock farmers, poor forage quality results in additional costs and more complex management:
-
Increased Feed Costs:
The need to purchase supplementary feed to compensate for the deficiencies of low-quality forage leads to higher expenses.
-
Reduced Animal Productivity:
Forage with poor nutritional value can reduce milk production and animal growth, directly affecting farm profitability.
Moreover, the addition of energy- or nitrogen-rich concentrates to offset the low quality of the forage can never fully replace the benefits of high-quality forage.
-
Increased Health Risks:
Consuming forage contaminated with moulds can cause diseases in livestock, increasing veterinary costs and animal losses.
Solutions and adaptations: tackling these challenges is all about strategy!
- Choice of Crops and Diversification:
Opt for forage plant varieties that are more resistant to moisture and diversify crops to spread the risks.
This year, all is not lost: second cuts and maize crops can help compensate, provided everything is done to secure yields and improve the nutritional value of your maize silage.
- Optimised Forage Drying and Storage:
Invest in efficient drying facilities and closely monitor storage conditions to prevent fermentation and mould.
Using silage preservatives may — or even should — be necessary this year to avoid additional losses in the pit, which would further degrade ration quality.
- Disease Monitoring and Management:
Implement regular monitoring programmes for crops and forage to quickly detect and treat fungal diseases.
Conclusion
Excessive and continuous rainfall poses a serious challenge to forage quality, with significant repercussions across the entire livestock production chain.
Farmers must adapt their practices and invest in effective solutions to maintain the quality and productivity of their farms.
Biosolutions for agriculture provide a range of natural and efficient means to achieve this.
Only a proactive and integrated management approach can overcome these weather-related challenges and ensure the sustainability of livestock farming during periods of heavy rainfall.
