The study aimed to identify the factors that influence university dropout among students of the professional career of Veterinary Medicine and Animal Husbandry at Universidad Nacional del Altiplano de Puno, Peru. The research had a descriptive, explanatory and cross-sectional approach, carried out with 365 undergraduate students, 53.97% of whom were male (n = 197), with an average age of 21.3 ± 3.4 years. Alcohol consumption was assessed using the CAGE scale (α = 0.8), and the presence of depressive symptoms was determined by applying the CES-D scale (α = 0.93). The University Student Dropout Scale - EDEU (α = 0.96) was used to determine factors of university student dropout, and the Rosenberg test was applied to assess self-esteem (α = 0.95). The multiple logistic regression model showed that students with low self-esteem had a 4.114-fold increased risk (95% CI [2.144–9.631]; p&l...

The study aimed to examine the excessive use of the Internet in the mental health of students of Veterinary Medicine and Zootechnics at the National University of the Alti-plano, Puno, Peru. The study was descriptive, explanatory and cross-sectional, carried out with 226 students (152 men and 74 women) from I to X cycle, aged 23.4 ± 5.5 years. Mental health was related to anxiety, depression and the sleep quality index. Internet use was quantified through a survey, exploring the time (h/day) of use during the last 30 days; anxiety and depression were determined through the Hamilton Rating Scale (HARS and HDRS), with internal consistency, α = 0.93 and 0.89, respectively; and the sleep quality index using the Pittsburgh questionnaire (α=0.87). The results indicate that depression (β= 0.292; p<0.001), anxiety (β = 0.229; p<0.001) and excessive use of the Internet (β = 0.178; p&l...

El objetivo del estudio fue evaluar el efecto del acetato de medroxiprogesterona (MAP) y gonadotropina coriónica equina (eCG) sobre la tasa de fertilidad, natalidad y prolificidad en ovejas criollas en época no reproductiva (anestro: ausencia de celo aparente) en condiciones de crianza familiar en la región Puno ubicada a 3905 msnm. Se utilizaron 40 primerizas y 40 multíparas, a las cuales se colocaron esponjas intravaginales (60 mg de MAP) durante 14 días. Al retiro de las esponjas se administró 500 UI de eCG a la mitad de los animales y las otra 20 quedaron como control (sin eCG). Las ovejas fueron inseminadas vía cervical con semen fresco de carnero Corriedale a las 48 h del retiro de las esponjas. La tasa de fertilidad (preñez) fue de 85 y 57.5% para ovejas con y sn eCG, respectivamente (p<0.001). la tasa de prolificidad en ovejas con y sin eCG fue de 185.3 y 100%, respect...
