Abstract

Improving productivity in semi-intensive sheep farming systems is
crucial for maximizing farm efficiency and profitability, especially in regions with
seasonal reproductive challenges. Estrus synchronization has emerged as a
promising approach to addressing these challenges and boosting overall farm
output. This study examines the effects of estrus synchronization on lambing rate
per ewe and milk yield, focusing on experimental and control groups in two
regions of Macedonia. Using hormonal induction (FGA + PMSG) to facilitate outof-
season lambing, experimental farms achieved an average of 3.25 lambs per
ewe over two years, compared to just 2.12 lambs in the control groups. Milk
production remained stable and consistent between the two groups,
demonstrating that enhanced lamb production can be achieved without
compromising milk yields. Furthermore, a comprehensive revenue analysis
revealed a 36% increase in total income for experimental farms, underscoring the
significant economic potential of this technique. These results suggest that estrus
synchronization offers a viable method to optimize both lamb production and
milk yields, leading to improved profitability in semi-intensive sheep farming
systems.
