Recent stagnation of agricultural TFP in LAC

20/11/2025 Go to Evidence

0.9% was the growth of agricultural Total Factor Productivity (TFP) in Latin America and the Caribbean between 2011 and 2020, signaling a marked slowdown in productivity (IBD, 2025).

Low-yield goat farming systems in the dry forest

21/10/2025 Go to Evidence

This study characterizes goat production systems in the Peruvian Amazonian tropical dry forest using multivariate analysis. Productive, reproductive, nutritional, health, and socioeconomic variables were evaluated to identify producer typologies and understand the dynamics affecting the efficiency of the goat system. The analysis allowed for the distinction of groups with differentiated practices and varying levels of technology, which is key to designing interventions aimed at improving productivity and sustainability (Rodríguez et al., 2025).

Effects of temperature on cattle

25/08/2025 Go to Evidence

A study of 159 Gyr crossbred dairy cows under tropical conditions in Peru compared two estrus synchronization protocols (conventional PC9 vs. extended J-Synch6) for follicular timed induction (FTAI) and evaluated their relationship with heat stress index (THI) in seven critical phases of the program. Both protocols showed similar estrus and pregnancy rates, but J-Synch6 produced larger preovulatory follicles, and its estrus manifestation was more sensitive to hours without heat stress (THI < 72) and to stress peaks (THI ≥ 83) during the follicular growth phase (Vásquez et al., 2025).
