Droughts present a formidable challenge to animal husbandry, severely impacting the availability and quality of natural forage and fodder. This leads to widespread feed scarcity, malnutrition, reduced productivity, and increased mortality rates among livestock. Effective feeding strategies during such crises are crucial not only for the immediate survival of animals but also for safeguarding the livelihoods of farmers heavily dependent on them. These strategies aim to optimize limited resources, maintain essential body condition, and prevent irreversible losses to the livestock population. The goal is to ensure the resilience of the animal wealth, which often acts as a cushion against the vagaries of nature for rural communities.
Feeding Strategies for Animals in Drought Situations
Drought conditions necessitate a multi-faceted approach to animal feeding, balancing immediate needs with long-term sustainability. The primary objective is to maintain the breeding herd's survival, prioritizing future recovery over immediate production.1. Feed Conservation and Management
- Early Weaning: Weaning young animals earlier reduces the nutritional burden on their dams, allowing adult females to maintain better body condition. This can cut nutrient requirements by one-third to one-half.
- Culling Non-Productive Stock: Removing non-productive, old, or weak animals from the herd aligns herd size with available feed resources, ensuring limited feed goes to productive animals.
- Rationing Stored Forages: Hay, silage, and other stored forages must be carefully rationed to extend their supply. Feed testing can help determine nutritional value and optimize usage.
- Fodder Banks: Establishing feed and fodder banks in drought-prone areas during times of surplus helps in making feed available swiftly during crises. Technologies like densified straw-based complete feed rations or compacted hay bales can reduce transportation costs.
2. Utilizing Alternative and Unconventional Feed Sources
Drought forces reliance on non-traditional feeds that can supplement poor-quality pastures.- Crop Residues: Straws from wheat, paddy, maize, and other grains, as well as stovers and groundnut haulms, can be used. Their nutritional value can be enhanced through treatments like urea ammoniation or mineral supplementation.
- Tree Leaves and Shrubs: Leaves from trees like mulberry, subabul, pipal, bamboo, and tapioca provide essential nutrients. Young leaves generally have higher protein content.
- Agro-industrial By-products: Ingredients like rice bran, oilseed cakes, molasses, and even bagasse (sugarcane residue) can be incorporated into rations to provide bulk and nutrients.
- Cactus: Spineless cactus can be a valuable feed source in dry areas, though it may need processing and supplementation.
3. Targeted Supplementation
Since drought-affected forages are often deficient in key nutrients, targeted supplementation becomes vital.- Protein Supplements: Oilseed cakes, lucerne meal, and urea-molasses blocks can address low digestible protein levels. Urea-molasses mineral blocks (UMMBs) are particularly effective in improving roughage utilization.
- Energy Sources: Cereal grains (barley, corn, wheat) and molasses prevent excessive weight loss. Grains should be introduced slowly over 10-14 days to prevent acidosis.
- Minerals and Vitamins: A complete mineral supplement, especially phosphorus, calcium, and trace minerals (zinc, copper), along with Vitamin A and D boosters, can correct deficiencies common in drought-affected feeds.
- Ration Formulation: Balanced rations must be formulated to meet the maintenance requirements of different animal categories (e.g., lactating vs. dry cows, young vs. adult).
4. Water Management
Adequate access to clean drinking water is as critical as feed. Water sources must be protected from contamination, and strategies for water conservation and delivery should be in place.5. Other Management Practices
- Parasite Control: During drought, animals graze closer to the ground, increasing parasite ingestion. Regular faecal worm egg counts and strategic deworming are essential.
- Monitoring Body Condition: Regularly assessing the body condition score of livestock helps in adjusting feeding levels to maintain reasonable animal health and welfare.
- Disease Prevention: Stress from drought can weaken immunity, making animals more susceptible to diseases. Vaccination programs should be up-to-date.
The government, through schemes like the National Livestock Mission (NLM) and the Animal Husbandry Infrastructure Development Fund (AHIDF), supports fodder development and infrastructure, which are crucial for long-term drought preparedness in the livestock sector.
Conclusion
Effective feeding strategies during drought are indispensable for mitigating its devastating impact on livestock. A combination of feed conservation, utilization of unconventional feed sources, and targeted nutritional supplementation, alongside prudent herd and water management, forms the cornerstone of drought resilience. These measures not only ensure the survival of animals but also safeguard the economic stability of millions of farmers. Long-term preparedness, supported by government initiatives like the National Livestock Mission, through fodder banks, entrepreneurial development for feed units, and research into drought-resistant forages, is crucial for building a sustainable and resilient livestock sector capable of withstanding future climatic shocks.
