Data or statistical facts on the situation and perspectives of agri-food systems and the impact of policies
In El Salvador, herd median (average number of milking cows in parentheses): Dairy: 285 (131) Beef cattle: 8.5 (0) Dual-purpose cattle: -Large extensions: 69 (21.8) -Medium extensions: 51 (17.5) -Small extensions: 23 (7.8) -Subsistence - high density: 15 (4.7) -Subsistence - low density: 10 (3.6) (IICA, 2024)
In El Salvador, for dairy farming: 21.8 L/d In dual purpose large extensions: 5.7 L/d In dual purpose medium extensions: 7.9 L/d In dual purpose small extensions: 5.6 L/d In dual purpose subsistence - high density: 5.6 L/d In dual purpose subsistence - low density: 6.0 L/d In beef cattle farming: not applicable (IICA, 2024)
The following production systems are identified: 1. Specialized dairy system. 2. Dual-purpose system. Subdivided into a) Large extensions. b) Medium extensions. c) Small extensions. d) Subsistence dual-purpose (Subdivided into: i. High animal density. ii. Medium animal density) 3. Meat production system.
The 166 kg represents the average initial live weight of 6.5-month-old Holstein heifers under tropical conditions in El Salvador (Corea et al., 2020).
The 124 g LWG/kg DM represents the average feed conversion with 360 g/kg CP of RUP, being 10 g LWG/kg DM higher than with 260 g/kg CP of RUP (Corea et al., 2020).
The 151 g/kg DM represents the crude protein content in cowpea hay, being 95.5 g/kg DM higher than pangola grass hay (55.5 g/kg DM) (Corea et al., 2020).
The 900 g/day represents the average live weight gain in heifers fed cowpea hay, being 90 g/day higher than those with pangola grass hay (Corea et al., 2020).
The 70.3% represents the apparent total tract digestibility of organic matter in cowpea hay diets, being 4.7 percentage points higher than pangola diets (Corea et al., 2020).
The 7.37 kg/day represents the average dry matter intake in heifers fed cowpea hay, being 0.42 kg/day higher than those fed pangola grass hay (Corea et al., 2020).
85% more effective are agricultural extension programs that incorporate digital components for technology transfer in Latin America, being fundamental to materialize innovations and connect research with producers according to CAF evaluations (Velásquez, A., 2025).
