University of the Altiplano, located in the district of Paucarcolla province and Region Puno, located at 3850 m.a.s.l. The aim of this research was to evaluate the agroecological production of quinoa ecotypes of colors (Chenopodium quinoa Willd.) by the use of Effective Microorganisms (EM); to evaluate the physical and chemical characteristics of the soil at the beginning and end of the experiment; to characterize the pigments of the quinoa ecotypes and compare production costs. The experiment was conducted under a randomized complete block design with a factorial arrangement of 9 x 3 x 2, of nine quinoa ecotypes, three doses of EM and two agroecological practices (organic matter and ornithological control) with 54 treatments in 3 blocks and a total of 162 experimental units. The soil analyzes were performed by routine procedures, the microbiological analysis was carried out by coun...

This study aimed to evaluate the relationship between body weight and body measurements of Corriedale sheep and get through these simple measurements in live animal models to predict weight. It was used 100 animals. There was a high correlation (r> 0.60) of body weight with body measurements, and the abdominal perimeter (PA) which showed greater correlation. It can be predicted body weight using the following equation: PV= -62.057 + 0.452PA + 0.222LoC + 0.557AH + 0.658LC + 0.578AL, resulting in a coefficient of determination of 0.76.

The aim of this study was to determine the metabolizable energy requirements for maintenance (MEm) and growth (MEg) of llamas and alpacas, by the comparative slaughter technique, at 4200 m above sea level. Twenty male llamas (106.6 ± 7.7 kg live weight, LW) and 20 male alpacas (55.7 ± 4.9 kg LW), both of two years of age, were subdivided into 5 groups of 4 animals each, per species. One group was slaughtered at the beginning of the study to measure the initial body energy content, and the remaining four groups were fed over a period of 55 days on a mixture of chopped hay of oats and Lucerne at four levels of feed (94.2% dry matter, DM): maintenance, intermediate low, intermediate high and ad libitum; corresponding to 40, 50, 60 and 70 g DM/kg LW0.75, respectively. All animals were slaughtered at the end of the experiment to determine retained energy (RE). Another group of four animals ...

El objetivo del estudio fue determinar los requerimientos de energía metabolizable de mantenimiento (EMm) y ganancia de peso vivo (EMg) de llamas y alpacas, mediante la técnica de sacrificio comparativo, a 4200 m de altitud. Se utilizaron 20 llamas machos (106.6 ± 7.7 kg de peso vivo, PV) y 20 alpacas machos (55.7 ± 4.9 kg PV), ambos grupos de 2 años de edad, divididos en 5 grupos de 4 animales por especie. Un grupo fue sacrificado al inicio del estudio para medir la energía corporal inicial, mientras que los cuatro grupos restantes fueron alimentados durante 55 días con una mezcla de heno picado de avena y alfalfa, en cuatro niveles de oferta de dieta (94.2% materia seca, MS): mantenimiento, intermedio bajo, intermedio alto y ad libitum; correspondientes a 40, 50, 60 y 70 g MS/kg PV0.75, respectivamente. Todos los animales fueron sacrificados al final del experimento para determi...
