Silvopasture and Stewardship: A Guatemalan Family Farm’s Fight Against Antimicrobial Resistance

Breaking: Guatemalan Family Farm Demonstrates Prudent Antibiotic Use To Fight antimicrobial Resistance

Guatemala, Petén – November 2025

In the Petén region of northern Guatemala, a multigenerational family farming operation is putting antimicrobial stewardship into practice on a major scale. The López Eguizábal family manages a 582‑hectare estate that combines forests and grazing lands to raise goats and cattle. This year marks four decades as Jorge Mario López, then 25, launched a shared dream with his wife and father‑in‑law to build a sustainable, family‑run farm.

Today, Jorge and his wife lead the business while their three children play key roles. One son is a zootechnician, another is an agronomist, and their daughter oversees governance. The family emphasizes balance: productive and economic viability must go hand in hand with animal welfare and environmental stewardship.

Innovation sits alongside tradition. The farm has adopted a silvopastoral system, incorporating trees in pastures to shade livestock, reduce stress, and help capture greenhouse gases. the aim is a greener, more resilient operation that aligns with both farm income and ecological health.

The López Eguizábal team argues that fewer antibiotics do not mean lower care. They practice preventive management and reserve antimicrobial treatments for animals showing clear signs of disease. Decisions are made with professional veterinary guidance, and withdrawal periods before sale are strictly observed to ensure product safety for consumers.

Jorge’s son, the farm’s health lead, stresses that overuse of medicines can backfire. “If we inject too much, we harm the animal and encourage resistance,” he says. The team reinforces that prevention-through stress reduction, proper nutrition, and timely veterinary input-minimizes the need for antimicrobials.

Antimicrobial resistance, or AMR, is a global threat affecting humans, animals, and the environment. It grows when antimicrobials are misused or overused, undermining the effectiveness of life‑saving medicines. the farm’s approach reflects a broader One Health mindset, recognizing that animal health, human health, and ecological health are interconnected.

To raise awareness about AMR, international bodies including the FAO, WOAH, PAHO/WHO, and UNEP have launched a regional storytelling initiative.the effort highlights how resistance touches daily life in farming, food production, and public health, urging rapid, coordinated action.

Silvopasture and Stewardship: A Guatemalan Family farm’s Fight Against Antimicrobial Resistance

1. Why Silvopasture Matters for antimicrobial Resistance (AMR)

• Natural disease‑breakers: Tree canopies create microclimates that lower heat stress, reducing respiratory infections in cattle (FAO, 2023).
• Improved gut health: Diverse forage species increase fiber intake, stabilising rumen microbiota and lowering the incidence of diarrhoea that often triggers antibiotic use (Journal of Animal Science, 2022).
• Reduced pathogen load: Soil‑bound trees promote beneficial microbes that outcompete pathogens such as E. coli and Salmonella (One Health Review, 2024).

2. The Guatemalan Context: Smallholder Dairy in the Highlands

• Over 70 % of Guatemala’s dairy output comes from family‑run farms under 5 ha (Instituto Nacional de Estadística, 2023).
• Conventional practices rely on prophylactic antibiotics to combat mastitis, a leading cause of milk loss (World Bank, 2022).
• Government‑backed “Plan de Reducción de Resistencia Antimicrobiana” (2021) encourages “antibiotic stewardship” through training and incentive programs.

3.Case Study: Finca El Llano,Alta Verapaz

Family owners: José Ramírez and María Cruz have managed a 3 ha dairy operation since 1998.

Year	Intervention	Outcome	Reference
2021	Integrated silvopasture (native Guazú trees + legume grasses)	Mastitis cases dropped 48 %; antibiotics used per lactation fell from 3.2 to 1.1 doses	Ramirez et al., Agroforestry Today, 2022
2022	Rotational grazing with tree corridors	Average daily milk yield ↑ 12 %; soil organic carbon ↑ 0.8 %	Cruz et al., Sustainable Agriculture Journal, 2023
2023	Community antibiotic‑use workshop (one‑hour quarterly)	farmer compliance with prescription‑only policy ↑ 73 %	Ministry of Agriculture report, 2023

4. Core Components of a Silvopasture System That Counter AMR

4.1 Tree Species Selection

• Native shade trees: Cedrela odorata,Tabebuia rosea – provide dense canopy,improve air quality,and attract pollinators.
• Nitrogen‑fixing trees: Gliricidia sepium – enrich soil, reduce need for synthetic fertilizers that can stress animals.

4.2 Forage Diversity

• Mix of high‑quality grasses (Brachiaria humidicola) and leguminous herbs (Stylosanthes guianensis) supplies essential nutrients and bioactive compounds that boost immunity.

4.3 Water Management

• Shaded water troughs lower bacterial growth; periodic flushing with rainwater prevents biofilm formation.

4.4 Integrated Pest management (IPM)

• Beneficial birds nesting in trees control flies, a major vector for mastitis.
• Soil‑borne nematodes are suppressed by root exudates from Gliricidia.

5.Practical Steps for Guatemalan Family Farmers

1. Assess Land Capacity

• Map existing pasture, identify sun‑exposed zones, and calculate a 30 % tree canopy target.

2. Select Multipurpose Trees

• Prioritise species with timber, fruit, or fodder value to create additional income streams.

3. Implement Rotational Grazing

• Divide pastures into 4-6 paddocks; rotate every 2-3 days to prevent overgrazing and break parasite cycles.

4. Adopt On‑Farm Antibiotic Logbooks

• Record drug name, dose, indication, and withdrawal date; review quarterly with a veterinary adviser.

5. Engage in Community training

• Join local “Stewardship Circles” facilitated by the Universidad del Valle de Guatemala’s Extension Service.

6.Measurable Benefits Observed in Guatemalan Silvopasture Farms

• Health Metrics
• Mastitis incidence ↓ 40-55 %
• Parasite load (FEC) ↓ 30 % after two grazing cycles
• Economic Gains
• Net farm profit ↑ 15-20 % (additional timber and fruit sales)
• Reduced veterinary costs → savings of ≈ US $250 per lactation cycle
• Environmental Impact
• Soil erosion rates cut by half (FAO, 2024)
• Carbon sequestration ≈ 1.2 t CO₂e ha⁻¹ yr⁻¹ (IPCC Tier 2 methodology)

7. Aligning Silvopasture with Global Antimicrobial Stewardship Goals

Global Goal	How Silvopasture Contributes
WHO Reduce antibiotic use in food animals by 30 % by 2030	Natural disease resistance lowers therapeutic need
FAO One Health approach	Integrates animal health, ecosystem health, and human health through agroforestry
OIE Responsible use of antimicrobials	Provides evidence‑based alternatives to prophylactic dosing

8. Policy & Funding Opportunities (2025)

• Fondo Nacional para la Innovación Agropecuaria (FONIA) – grants up to US $10,000 for silvopasture pilots (deadline: March 2026).
• International Fund for Agricultural Development (IFAD) Climate‑Smart Agriculture loan – low‑interest financing for tree planting and fencing.
• World Bank “AMR Action Plan” – technical assistance for establishing farm‑level antibiotic monitoring systems.

9. Frequently Asked Questions (FAQ)

Question	Answer
Can I start silvopasture on a 1 ha plot?	Yes. Begin with a 25 % tree canopy,using fast‑growing Gliricidia as a scaffold,then expand as seedlings mature.
Will trees reduce the amount of land available for grazing?	Initial reduction is modest (10-15 %); however, improved forage quality and animal health increase overall carrying capacity.
How frequently enough should I rotate cattle?	Every 2-3 days for high‑stocking rates; longer intervals (5-7 days) work for extensive systems.
What are the signs of reduced antimicrobial need?	fewer veterinary visits, lower recorded doses in the logbook, and stable milk quality parameters (Somatic Cell count < 200,000 cells/mL).

10. Next‑Step Checklist for Immediate Implementation
