Goat farming constitutes a significant source of income for farmers in northern Peru. There is currently an absence of information about the genetics of Peruvian Creole goats that would enable us to understand their origins and genetic spread. The objective of this study was to estimate the genetic diversity of Creole goats from northern Peru using...

The creole cattle was originated after the introduction of cattle into America 5 centuries ago. Currently, the production traits of Peruvian creole cattle is scarcely known. An important characteristic of the creole cattle is its adaptability to different extreme environments. However, to date, molecular studies in Peruvian creole cattle are still...

The alpaca population mostly consists of the Huacaya phenotype and is widely distributed in Southern Peru. This study aimed to estimate the genetic diversity and population structure of two Huacaya alpaca populations (Ajoyani and Quimsachata) using fourteen and twelve microsatellite markers for each population, respectively. A total of 168 alpaca b...

New-generation sequencing technologies, among them SNP chips for massive genotyping, are useful for the effective management of genetic resources. To date, molecular studies in Peruvian cattle are still scarce. For the first time, the genetic diversity and population structure of a reproductive nucleus cattle herd of four commercial breeds from a P...

The Peruvian creole cattle (PCC) is a neglected breed and an essential livestock resource in the Andean region of Peru. To develop a modern breeding program and conservation strategies for the PCC, a better understanding of the genetics of this breed is needed. We sequenced the whole genome of the PCC using a de novo assembly approach with a paired...

Early assessment of crop development is a key aspect of precision agriculture. Shortening the time of response before a deficit of irrigation, nutrients and damage by diseases is one of the usual concerns in agriculture. Early prediction of crop yields can increase profitability for the farmer’s economy. In this study, we aimed to predict the yield...

The Peruvian creole cattle (PCC) is a neglected breed, and is an essential livestock resource in the Andean region of Peru. To develop a modern breeding program and conservation strategies for the PCC, a better understanding of the genetics of this breed is needed. We sequenced the whole genome of the PCC using a paired-end 150 strategy on the Illu...

El objetivo del estudio fue estimar los componentes de varianzas, la heredabilidad y correlaciones genéticas y fenotípicas de los rasgos productivos de las líneas de cuyes Saños y Mantaro, desarrolladas en la Estación Experimental Agraria Santa Ana, Junín (Perú). Se calculó además la consanguinidad de las dos líneas. Se analizaron los registros des...

Cattle spread throughout the American continent during the colonization years, originating creole breeds that adapted to a wide range of climate conditions. The population of creole cattle in Peru is decreasing mainly due to the introduction of more productive breeds in recent years. During the last 15 years, there has been significant progress in...

We sequenced for the first time the complete mitochondrial genome of a Peruvian creole cattle using next generation sequencing

Background One of the biggest challenges in the swine industry is to increase female reproductive efficiency. Recently, vulva score categories (VSC), assessed prior to puberty, has been proposed as an indicator trait of efficient reproductive performance in sows. The objective of this study was to validate the use of VSC as an indicator trait for r...

El objetivo del estudio fue determinar los parámetros productivos y reproductivos de las líneas de cuyes Saños y Mantaro, desarrollados en la Estación Experimental Agraria Santa Ana, en la sierra central del Perú. Se analizaron registros de los años 2017 al 2020 de 1773 y 1888 cuyes de la línea Saños y Mantaro, respectivamente. Los parámetros produ...

La problemática del uso de suelos de aptitud forestal en las regiones áridas y semiáridas presenta escasez de lluvias y baja calidad de suelos, por ello, es importante buscar alternativas que permitan superar estos inconvenientes. El presente tiene como objetivo evaluar el efecto del Poliacrilato de Sodio (PANa) de pañales desechables usados en la...

La quinua es considerada una especie con potencial agronómico en la región andina. El objetivo del estudio fue evaluar el rendimiento, las características agronómicas y morfológicas de 11 genotipos de quinua (Chenopodium quinoa Willd.) durante dos campañas agrícolas. Se utilizó el análisis de varianza de dos vías con interacción para evaluar los ef...

Vicia sativa is one of the most important crops for livestock feed. Pods from Vicia sativa seed production are usually discarded. The objective of this study was to report the nutritional value of Vicia sativa pods. Report of the bromatological analysis was 17.58% for crude protein, 44.96% for neutral detergent fiber, and 55.81% for in vitro dry ma...

Background: Reproductive performance is critical for efficient swine production. Recent results indicated that vulva size (VS) may be predictive of reproductive performance in sows. Study objectives were to estimate genetic parameters, identify genomic regions associated, and estimate genomic prediction accuracies (GPA) for VS traits. Results: H...

Reproductive efficiency is critical to maximizing productivity in the swine industry. A recent study indicated that vulva score (VSC) assessed prior to puberty may be predictive of reproductive performance in sows, in which gilts with greater VSC had greater reproductive performance. The objective of this study was to validate the effect of VSC on...

Recent results indicated that vulva size measured prior to puberty may be predictive of reproductive performance in sows. Therefore, the objective of this study was to estimate genomic prediction accuracies for vulva size traits in purebred gilts. A total of 1,185 Landrace (n = 477) and Yorkshire (n = 708) gilts originated from two different lines...

Reproductive performance is critical for efficient swine production. A relationship between the size of the vulva measured in gilts prior to puberty at 15 weeks of age and subsequent reproductive performance has been demonstrated. The objective of this study was to estimate genetic parameters and perform genomic analysis on vulva size traits. A tot...

Se aplicó un programa de enriquecimiento ambiental a pumas (Pumas concolor) del Parque Zoológico Taraccasa en Abancay (Apurímac, Perú) con el objetivo de monitorear cambios de conducta. Se observaron cuatro pumas (tres hembras, un macho) de 3 a 9 años de edad. Se utilizaron cuatro tipos de enriquecimiento ambiental: físico (taburetes de madera, tro...

The objective of the study was to establish the profile of the main physical characteristics of the alpaca fibre that can serve for a better commercialization and for breeding purposes. Measurements were made of 145 white and coloured fibre samples (brown and dark shaded) from five communities of the district of Cotaruse, Apurímac, Peru, using the...
