Creole high Andean cattle have family economic importance in rural inhabitants, contribute to food security. The objective of this study was to evaluate the quantity, quality, and nuclear status of the ovarian oocytes according to the body condition of the Creole cows. Groups of cows were formed according to body condition (1=emaciated, 5=obese): low (≤1.5), moderate (2 to 2.5) and high (≥3). The ovaries (n=212) were obtained from Creole cows from the slaughterhouse. The oocytes were recovered by follicular aspiration classifying into categories A, B and C, placing a part with ethanol-acetic acid (3:1) for 24 h, then stained with 2% Lacmoid. The nuclear status of the oocyte was evaluated, categorizing as an intact germinal vesicle (GV) and germinal vesicle breakdown (GVBD). The number of oocytes retrieved per ovary between low, moderate and high body condition of the cows were similar (p>0.05). There was an association between body condition and quality of oocytes of category A (rs=0.49; p=0.001), B (rs=0.16; p=0.018); C (rs=-0.16; p=0.016). A higher percentage (p≤0.05) of category A and B oocytes were obtained in those with moderate and high body condition, as category C in low body condition. Body condition did not influence (p>0.05) on the nuclear state of the oocyte. No association (p=0.073) was found between body condition and oocytes with intact GV, nor with GVBD (p=0.737). It is concluded that the body condition is associated with the quality of category A, B and C oocytes, but not with the GV and GVBD nuclear status in Creole cows from the slaughterhouse. |

El objetivo de este estudio fue evaluar la cantidad, calidad y estado nuclear de los ovocitos de ovarios según condición corporal de las vacas criollas. Se formó grupos de vacas según condición corporal (1=emaciada, 5=obesa): baja (≤1,5), moderada (2 a 2,5) y alta (≥3). Los ovarios (n=212) fueron obtenidos de vacas criollas del matadero. Los ovocitos se recuperaron mediante aspiración folicular clasificando en categorías A, B y C, colocándose una parte con etanol-ácido acético (3:1) por 24 h, luego teñidos con Lacmoid al 2%. Se evaluó el estado nuclear del ovocito, categorizando como vesícula germinal intacta (GV) y vesícula germinal rota (GVBD). El número de ovocitos recuperados por ovario entre condición corporal baja, moderada y alta de vacas fueron similares (p>0,05). Hubo asociación entre condición corporal y calidad de ovocitos de categoría A (rs=0,49; P=0,001), B (rs=0,16; p=0,018); C (rs=-0,16; p=0,016). Se obtuvieron mayor porcentaje (p≤0,05) de ovocitos de categoría A y B en las de condición corporal moderada y alta, como categoría C en condición corporal baja. La condición corporal no influyó (p>0,05) sobre el estado nuclear del ovocito. No se encontró asociación (p=0,073) entre condición corporal y ovocitos con GV intacta, ni con GVBD (p=0,737). Se concluye, que la condición corporal se asocia con la calidad de los ovocitos de categoría A, B y C, mas no con el estado nuclear GV y GVBD en vacas criollas del matadero.Universidad Nacional del Altiplano2021-08-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/xml//huajsapata.unap.edu.pe/index.php/ria/article/view/29410.18271/ria.2021.294Revista de Investigaciones Altoandinas - Journal of High Andean Research; Vol. 23 No. 3 (2021); 133-138Revista de Investigaciones Altoandinas - Journal of High Andean Research; Vol. 23 Núm. 3 (2021); 133-1382306-85822313-2957reponame:Revista de Investigaciones Altoandinasinstname:Universidad Nacional del Altiplanoinstacron:UNAPspa//huajsapata.unap.edu.pe/index.php/ria/article/view/294/209//huajsapata.unap.edu.pe/index.php/ria/article/view/294/218Derechos de autor 2021 Revista de Investigaciones Altoandinasinfo:eu-repo/semantics/openAccessoai:huajsapata.unap.edu.pe:article/2942021-11-09T09:01:36Z |
