“…Increasing the reproductive capacity of the flock can be an alternative to improve the productivity and profitability of the flocks. The reduction of the unproductive period of the sheep can diminish fixed production costs and variables and increase production, obtaining three births per ewe in two years (Hinojosa-Benavides et al, 2019).…”

Productivity and profitability in sheep production systems are strongly influenced by the reproductive capacity of the flock. Objective: To evaluate the use of reproductive biotechnologies (e.g., the induction of estrus) and its impact on the economic efficiency and the productive and reproductive performance of technified sheep production systems, during the seasonal anestrus. Design/Methodology/Approach: Four-hundred recently weaned (60 days postpartum) ewes of the Katahdin breed were randomly divided into two treatments: T1 = natural mating (n= 200) and T2 = induction of estrus (n=200). Estrus was induced through the application of intravaginal sponges, impregnated with 20 mg of chronolone, plus the injection of 400 IU of Equine Chorionic Gonadotropin. The aim was to evaluate the reproductive and economic efficiency of the flock. Results: The induction of estrus during the seasonal anestrus recorded increases (p<0.001) in prolificacy (32%), fertility (86%), and kilograms of lamb weaned per year per ewe (48%), while decreases (p <0.05) were recorded in the number of open days (25%), calving interval (11%), cost per open days (23%), and the kilograms of lamb required per ewe per year (10%). Study Limitations/Implications: The constant variations in the price of supplies and services caused changes in the economic indicators. Findings/Conclusions: The use of reproductive biotechnologies (such as estrus induction) has a positive impact on production units, improving their profitability.

El objetivo fue analizar el efecto de esta biotecnología reproductiva en la producción de ovinos, principalmente en aspectos fundamentales como: eficiencia reproductiva, mejoramiento genético, transferencia de tecnología al campo y capacitación del productor; todo finalmente reflejado en la productividad y la rentabilidad de la producción ovina, teniéndose en cuenta también todos los factores que afectan al correcto desarrollo de la inseminación artificial, evitando los momentos de más calor o frío ambiental y practicando el flushing si el estado general de las ovejas lo aconseja. Se concluyó que las diferencias entre los resultados obtenidos por las diferentes explotaciones son altamente significativas.
