Garantizar la inclusión y la equidad es fundamental para alcanzar una educación de calidad. Por ello, este estudio tiene como objetivo evaluar el nivel de inclusión educativa a través de la aplicación del instrumento Index for Inclusion, con el fin de identificar las limitaciones presentes en la cultura, las prácticas y las políticas inclusivas. El diseño metodológico adoptado es cuasi experimental. La población objeto de estudio la constituyen docentes hombres y mujeres de la Unidad Educativa Bicentenario, ubicada en la ciudad de Quito. El cuestionario Index for Inclusion es una herramienta validada y utilizada en diversos países, compuesta por 45 ítems distribuidos en tres dimensiones: cultura, políticas y prácticas inclusivas, con respuestas tipo Likert. La recolección de datos se realizó en línea mediante Google Forms, obteniendo información de 61 docentes, considerando variables independientes como sexo, edad, años de experiencia y el subnivel educativo en el que laboran. Dado que las variables dependientes son de tipo ordinal, el análisis se efectuó a través del modelo logístico ordinal utilizando el software estadístico SPSS. Los resultados revelan que los subniveles de educación básica elemental y media presentan mayores niveles de inclusión en comparación con la básica superior y el bachillerato. Además, se observó que los docentes más jóvenes emplean con mayor eficacia los recursos dentro de un enfoque de escuela inclusiva. Una limitación destacada del estudio es la falta de investigaciones sobre el Index for Inclusion en el contexto ecuatoriano, lo que impidió realizar comparaciones con otros estudios similares.

BackgroundAntimicrobial resistance (AMR) is a global concern impacting both humans, animals and their environment. The use of oral antimicrobials in livestock, particularly in pigs, has been identified as a driver in the selection of AMR bacteria. The aim of the present study was to evaluate the effects of a single intramuscular (IM) dose of marbofloxacin (8 mg/kg) on Enterobacteriaceae and E. coli populations, as well as on fluoroquinolone resistance within the fecal microbiota of pigs. Twenty healthy pigs, 60-days old, were divided into two groups: a treated group (n = 13) and a control group (n = 7) and were monitored over a 28-day experimental period. Fecal samples were collected from all animals for the isolation of E. coli and Salmonella strains. The minimum inhibitory concentration (MIC) of marbofloxacin for the isolates recovered on MacConkey agar supplemented with 1 or 4 µg/mL of marbofloxacin and for some generic E. coli isolates (recovered from MacConkey agar not supplemented with marbofloxacin) was determined using the broth microdilution method. Genomic DNA was extracted from the confirmed bacterial strains and sequenced using the Sanger method to identify mutations in the quinolone resistance determining regions (QRDRs) of the gyrA and parC genes.ResultsThe single IM administration of marbofloxacin resulted in a significant decrease in Enterobacteriaceae and E. coli fecal populations from days 1 to 3 post- treatment. No Salmonella isolates were detected in either group, and no marbofloxacin-resistant E. coli isolates were identified. The MIC of the selected generic E. coli strains (n = 100) showed an increase to up to 0.5 µg/mL between days 1 and 3 post-treatment but remained below the clinical breakpoint of marbofloxacin resistance (4 µg/mL). Sequencing of these isolates revealed no mutations in gyrA and parC genes.ConclusionsThe present study showed that this dosing regimen of marbofloxacin significantly decreases the fecal shedding of Enterobacteriaceae and E. coli populations in pigs, while limiting the selection of marbofloxacin-resistant E. coli isolates. These findings warrant validation in sick pigs to support the selective use of this antibiotic solely in cases of clinical disease, thereby minimizing the reliance on conventional (metaphylactic) group treatments in pigs.

Postpartum dysgalactia syndrome (PPDS) is a common disorder affecting sows in intensive production systems. In most cases, hypogalactia is not clearly identified and assumes a subclinical aspect. Therefore, the present study aimed to evaluate the effect of a nonsteroidal anti-inflammatory drug (NSAID) based on tolfenamic acid as a prophylactic treatment for PPDS and the performance of suckling piglets. Gilts (n = 319) were randomly divided into two groups: a tolfenamic acid group (n = 157) and a control (n = 162). The tolfenamic acid group received a single intramuscular injection (1 ml/20 kg of 4% tolfenamic acid) after farrowing, whereas the control group received no treatment. The occurrence of PPDS was confirmed. All piglets (n = 4,466) were weighed at 1, 4, and 18 days of age. All litters were evaluated for weight gain, the occurrence of diarrhea, and mortality between 4 and 18 days of age. PPDS variables were analyzed using logistic regression. Piglet weights were analyzed based on covariance while considering the effects of initial weight and the presence of diarrhea. Tolfenamic acid had no significant effect on the incidence of PPDS. The tolfenamic acid group had a 0.41% lower piglet mortality rate until 18 days of age. Tolfenamic acid administered prophylactically to gilts after farrowing reduced piglet mortality during lactation and promoted weight gain.

ObjectiveThis study investigated the effects of administering saline, 100 or 250 μg of gonadotrophin releasing hormone (GnRH) on ovarian response, synchrony of oestrus and ovulation and chronic stress response in Bos indicus cattle.DesignRandomised control.MethodsAnimals were either left untreated (n = 20) or on day 0 treated with an intravaginal progesterone releasing device and either saline (n = 24), 100 μg (n = 35), or 250 (n = 35) μg of GnRH, intramuscular (IM). Blood was sampled 1.4 h after administration of treatment to monitor concentrations of luteinising hormone (LH) and P4 in serum and again 5 days later. On day 5 intravaginal P4 releasing device were removed, cloprostenol was administered IM and again 8 h later. Oestrus and ovulation were then monitored with ultrasonography for 6.5 days. Hair was clipped on day 55 for analysis of hair cortisol concentrations (HCC).ResultsNo significant differences were found between Saline and GnRH treatments in the odds of inducing a new corpus luteum (CL) and the synchrony of oestrus or ovulation. HCC did not differ significantly between treatments. Mean concentrations of LH in serum on day 0 were less in the Saline compared to 100 and 250 μg GnRH treatments but did not differ between different doses of GnRH.ConclusionMean concentrations of LH and the odds of inducing a new CL were not increased after administering 250 μg compared to 100 μg of GnRH. Animal handling events in the study did not influence HCC. Further research is needed to better optimise responses to GnRH in B. indicus cattle.

Abstract BackgroundReproductive performance on commercial farms depends on the ability to identify sexual behavior and breed females during estrus. The presence of a boar is essential in determining sow sexual behaviors and is greatly mediated by the adult boar odor. This study sought to examine the effects of a novel boar salivary pheromone on weaned sow sexual receptivity and subsequent reproductive performance. MethodsOne hundred weaned sows were randomly assigned to either a control treatment where sows were exposed during heat detection to a live mature boar (BG) or to BOARBETTER® (Vétoquinol, Lure, France), given as a single spray while a boar grunting audio file was played (PG). Sexual behaviors were assessed twice daily during a Back-Pressure Test (BPT). Sows expressing behavioral estrus were mated. Ultrasound was used to assess ovarian activity from weaning until the end of ovulation. Reproductive and prolificacy data were collected until farrowing.ResultsTwelve sows were eliminated from the study because of early ovulation, no ovulation, or infectious disease. Breeding rate did not differ between the two treatments (BG: 100% vs PG: 91%). Sows in the BG had a shorter wean-to-estrus interval (97 vs 108 h) and longer estrus duration than PG sows (57 vs 39 h; p < 0.05). Wean-to-ovulation interval did not differ but onset of estrus to ovulation interval was longer in PG compared with BG sows (40 vs 30 h, p < 0.01). Follicle size at the onset of estrus was larger among PG than BG sows (5.76 vs 5.43 mm, p = 0.04). Timing of ovulation relative to insemination did not differ between the two treatment groups. Pregnancy rates were identical or similar for sows in the two treatment groups (93%) as was number of pigs born per litter.ConclusionsExposing weaning sows to the novel pheromone and the boar grunting sound achieved high estrus detection rate. Estrus was delayed and shortened but sows were successfully bred and were farrowed. Despite the absence of teaser boar, the procedure incorporating the novel pheromone and the boar grunting sound was shown to be efficient for sow breeding.
