| dc.description | Bovine livestock is a fundamental pillar within the agricultural sector of Ecuador, it contributes to the dynamism of the rural peasant economy with meat and milk products, which are part of the basic basket and food security of the country. The study was carried out on the dos Potrillos cattle producing farm, located in the Montalvo canton, province of Los Ríos. The objective of this experimental work was to evaluate the use of the hormone progesterone post insemination to reduce gestational loss in Jersey cows. 20 Jersey cows, reproductive hormones, progesterone-based vaginal device, injectable progesterone and ultrasound were used. The application of exogenous P4 has numerical influence on pregnancy results between treatments. The injectable progesterone treatment (p4), 1cc (150mg) applied 14 days after artificial insemination, obtained higher percentages in relation to the control group: 40%; 30% Respectively. The results of the study allow us to conclude that the cows that were supplemented with Injectable P4, 1cc (150mg) at 14 days. They presented concentrations (ng/mL) in blood plasma at 14 (1.94) and 24 (8.14) days. The body condition of the cows, the climate and herd management can affect the pregnancy rate. The cost per pregnant cow is related to the synchronization protocol, hormone prices and technical services | es_ES |

| dc.description.abstract | el uso de la hormona progesterona post inseminación para disminuir la pérdida gestacional en vacas Jersey. Se utilizaron 20 vacas de la raza jersey, hormonas reproductivas, dispositivo vaginal a base de progesterona, progesterona inyectable y ecógrafo. La aplicación de P4 exógena tiene influencia numérica en los resultados de preñez entre los tratamientos. El tratamiento de progesterona inyectable (p4), 1 cc (150 mg) aplicada a los 14 días post inseminación artificial, obtuvieron mayores porcentajes en relación al grupo control: 40%; 30% Respectivamente. Los resultados del estudio permiten concluir que las vacas que fueron suplementadas con P4 Inyectable, 1cc (150mg) a los 14 días. Presentaron concentraciones (ng/ml) en plasma sanguíneo a los 14 (1,94) y 24 (8,14) días. La condición corporal de las vacas, el clima y manejo del hato puede afectar, la tasa de gestación. El costo por vaca preñada está relacionado con el protocolo de sincronización, precios de las hormonas y servicios técnicos. | es_ES |
