Abstract

Objective. To evaluate if female Blackbelly ewes are affected by heat stress (HS) during the summer under tropical conditions. Materials and methods. In the experiment, female sheep were divided into two treatments (7 female lambs and 14 multiparous ewes) to evaluate the effect of HS through the temperature and humidity index (THI), physiological and hematological variables. Results. During the study, a THI between 77 and 88 U was found. Likewise, respiratory frequency (RF) was higher in the T2 in the afternoon (117 bpm) than in the morning (114 bpm) (p<0.05). Also, it was found that rectal temperature (RT) was higher in T1 in the afternoon (39.3°C) than in the morning (38.9°C) (p<0.05). Finally, it was found that the heart rate (HR) was higher in t2 during the afternoon (p<0.05). Hematocrit (HCT) and hemoglobin (HB) variables were similar between groups during the study, but there were differences between samples two through seven (higher concentrations) compared to sample 13 (lower concentration) (p<0.001). Finally, the hydrogen potential (pH) variable presented variations, with samplings three and six being the highest, and samplings four, five, seven, and twelve being the lowest values (p<0.001). Conclusions. Female Blackbelly ewes presented severe HS during the summer in the tropics. [ABSTRACT FROM AUTHOR]

Abstract

Objetivo. Determinar si las hembras ovinas Blackbelly son afectadas por el estrés calórico (EC) durante el verano en un clima tropical. Materiales y métodos. En el experimento, 21 hembras ovinas fueron divididas en dos tratamientos (T1=7 corderas y T2=14 ovejas multíparas) para evaluar el efecto del EC a través del índice de temperatura y humedad (ITH), variables fisiológicas y hematológicas. Resultados. En el experimento se encontró un ITH de entre 77 y 88 U. Asimismo, la frecuencia respiratoria (FR) fue mayor en el T2 por la tarde (117 rpm) que por la mañana (114 rpm) (p

Abstract

El objetivo general de la investigación fue proporcionar información de las técnicas de inseminación artificial cervical en ovejas pelibuey con semen fresco en la provincia de San Martín, como objetivos específicos fueron: evaluar el comportamiento reproductivo de ovejas pelibuey post inseminación artificial cervical con semen fresco en la provincia de San Martín y describir el proceso de la técnica de inseminación artificial cervical en ovejas pelibuey con semen fresco en la provincia de San Martin. La investigación fue de tipo aplicada con un nivel descriptivo; para la ejecución del estudio se realizó la Inseminación artificial con semen fresco a 19 ovejas pelibuey multíparas ciclando entre 3-4 años de edad, con la condición corporal de 2.5. y un peso promedio de 30 kg. Los resultados obtenidos demostraron que por medio de la IA tipo cervical se preñó al 47% de ovejas en celo. Además, se obtuvo una estadística descriptiva sobre el tiempo de gestación en ovejas pelibuey con una desviación estándar de 5,025 y una varianza de 25,250; asimismo, se obtuvo la estadística descriptiva del tiempo transcurrido al próximo celo de las ovejas pelibuey que no lograron preñar mediante la IA, con una desviación estándar de 3.3 y varianza de 10.89. Se concluye, que la Inseminación artificial tipo cervical es una excelente técnica que nos ayuda a mejorar la calidad del hato ovino. The general objective of the research was to provide information on the techniques of cervical artificial insemination in Pelibuey ewes with fresh semen in the province of San Martín, as specific objectives were: to evaluate the reproductive behavior of Pelibuey ewes post cervical artificial insemination with fresh semen in the province of San Martin and describe the process of the cervical artificial insemination technique in Pelibuey ewes with fresh semen in the province of San Martin. The research was of an applied type with a descriptive level; For the execution of the study, artificial insemination with fresh semen was performed on 19 multiparous pelibuey ewes cycling between 3-4 years of age with a body condition of 2.5. and an average weight of 30 kg. The results obtained showed that by means of the cervical type AI, 47% of ewes in heat were impregnated. In addition, a descriptive statistics was obtained on the gestation time in Pelibuey ewes, where a standard deviation of 5.025 and a variance of 25.250 were obtained; Likewise, the descriptive statistics of the time elapsed to the next heat of the Pelibuey ewes that did not manage to get pregnant through AI were obtained, with a standard deviation of 3.3 and variance of 10.89. It is concluded that cervical artificial insemination is an excellent technique that helps us improve the quality of the sheep herd.
