Efecto de la ozonoterapia o el tratamiento alopático sobre la endometritis post-parto en vacas y análisis económico de los tratamientos.
(2015) Narvaez Teran, Jhonny Alfredo
El período posparto es considerado un momento muy importante en la vida de la vaca, debido a su gran influencia sobre la eficiencia reproductiva. En esta fase suelen aparecer las enfermedades uterinas posparto especialmente en los hatos lecheros (Duricic et al., 2014). La endometritis (inflamación del endometrio) en vacas provoca intervalos entre partos muy prolongados, incremento de los servicios por concepción y presencia de residuos de antibióticos en la leche, cuando se realizan terapias farmacológicas antimicrobianas. Del 5 al 35% de repeticiones de las inseminaciones en un hato se deben a la endometritis subclínica (SE) que no es tratada a tiempo provocando pérdidas productivas y económicas (Zobel, 2013). Una alternativa al uso de antibióticos es la ozonoterapia ya que no provoca efectos residuales perjudiciales para el consumo humano y animal y no causa impacto ambiental (Purohit et al., 2015). El objetivo de este proyecto fue evaluar el efecto de la ozonoterapia frente a un tratamiento alopático y el posterior análisis económico de ambos en vacas con endometritis post-parto.
Efecto de la ozonoterapia sobre el intervalo parto-celo y la fertilidad en vacas lecheras
(Editor Universidad de Cuenca, 2015) Araujo, Judith Oliva; Argudo, Ja; Narvaez Teran, Jhonny Alfredo; Galarza Lucero, Diego Andrés
En la vaca lechera la atención médica del puerperio es fundamental en los programas de manejo reproductivo. Durante este periodo se diagnostican y tratan patologías del útero con el propósito de acortar el periodo de espera voluntaria (Djuricic et al., 2012a). La ozonoterapia como medicina alternativa, es usada en tratamientos de mastitis y otros procesos infecciosos reproductivos intrauterinos (endometritis, metritis, etc.). El Ozono tiene propiedades desinfectantes, antivirales, y antibacterianas sistémicas, mejora el metabolismo celular, aumentando el número de glóbulos rojos, oxigenando mejor la sangre y aumentando la presión arterial, de esta manera la sangre pasa más rápido por las partes afectadas ejerciendo así un efecto positivo sobre los tejidos (Djuricic et al., 2012b). El objetivo del trabajo fue evaluar el efecto de la ozonoterapia sobre el intervalo parto-celo y la fertilidad de las vacas.
Effect of estradiol benzoate on the size of follicle and corpus luteum of Holstein cows treated with D-cloprostenol (2015)
(2015) Soria Parra, Manuel Elías; Narvaez Teran, Jhonny Alfredo; Torres Inga, Carlos Santiago; Méndez Álvarez, María Silvana; Soria Parra, Carlos Alonso
The effect of two treatments, farms, and body shape on the size of the follicle and Corpus Luteum were evaluated. D-Cloprostenol (150 ug) was used in one of the treatments; in the other, D-Cloprostenol (150 ug) and Estradiol Ben-zoate (1 mg), were used. Two groups of 32 Holstein dairy cows each, from the Nero and Irquis farms in Cuenca, Ec-uador, were set up. Body condition (2.75-3.50) was considered. The calving number was 1-6; the farms, Irquis and Nero; and animal age, 3-10 years. Ultrasound scanning was used on days 0; 3 and 7, in order to measure the Luteum first, then the dominant ovarian follicle, and finally, the Corpus Luteum. Factor analysis of variance was performed. No significant differences were found for follicle size due to any factors; nor due to interaction. Concerning luteum, significant differences (P < 0.05) were observed for the treatments and for the farm. The values were 0.33 cm higher for the treatment with Benzoate, and 0.36 cm, at Irquis, in comparison to Nero. The treatment with Benzoate, along with better husbandry at Irquis played a critical role in the appearance and evolution of the luteum.
Estudio exploratorio de valores hematológicos en terneras Holstein Frisian mestizas, durante los primeros seis meses de vida
(2018) Palacios Ordoñez, Teofilo Estuardo; Narvaez Teran, Jhonny Alfredo
Age-related changes in hematological values occur in almost all mammalian species, and published studies that include repeated measurements of hematological parameters in calves during the first months of life are limited. The objective of the present investigation was to determine the hematological values with sequential measurements from birth to 6 months of age in calves of the Holstein breed Frisian mestizas, in the Nero farm located at 3000 masl. Blood samples were taken from 36 clinically healthy heifers, hematological tests were performed on automatic cell counters for veterinary use and calibrated for the bovine species. The results were processed using the software SPSS version 22, in which the minimum, maximum, average and the standard deviation for the age in days and the hematological values were calculated. In addition, from the descriptive statistics the Pearson Correlation test was applied to establish whether there is a correlation between the evaluated values with respect to age. The significance levels were established to two tails for both p≤0.01(**) and p≤0.05(*). In conclusion, it can be stated that most correlations evidenced have a low association with age, however, the MCV[1] has an average association (Pearson Correlation -0.531**, R2 = 0.28), which decreases to as the age of calves increases.[1] MCV: Medium Corpuscular Volumen
Uso de la ozonoterapia intrauterina para tratar la endometritis subclínica en vacas repetidoras de servicios
(2022) Narvaez Teran, Jhonny Alfredo
Subclinical endometritis (SS) is endometrial inflammation usually determined by cytology, in the absence of purulent material in the vagina. In animals without signs of clinical endometritis, the subclinical form of the disease is diagnosed by measuring the proportion of neutrophils present in samples collected by washing the uterine lumen or using a cytobrush. Uterine pathologies play a primary role in reducing reproductive efficiency, with delays in the return of postpartum ovarian activity, increased calving-first service and calving-conception intervals, decreased pregnancy rates from 56% to 30 %, increased number of services per conception and higher culling rates. At present, the different therapeutic treatments such as ozone therapy are focused on improving the intrauterine environment for the survival of the embryo, arousing interest in using alternative therapies to antibiotics applied intrauterinely against uterine infectious processes. The objective of this research was to evaluate the effect of ozone therapy in the treatment of subclinical endometritis in repeating cows
