Infectious pancreatic necrosis (IPN) is a viral disease with considerable negative impact on the rainbow trout (Oncorhynchus mykiss) aquaculture industry. The aim of present work was to detect genomic regions that explain resistance infectious virus (IPNV) in trout. A total 2,278 fish from 58 full-sib families were challenged IPNV and 768 individuals genotyped (488 resistant 280 susceptible), using 57K SNP panel Axiom, Affymetrix. genome-wide association study (GWAS) performed phenotypes...
The objective of this study was to fit four nonlinear models (Brody, von Bertalanffy, Gompertz and Logistic) realizations llama weight, using frequentist Bayesian approaches. Animals from both sexes types (K'ara Ch'accu) were observed. Data consisted 43,332 monthly body weight records, taken birth 12 months age 3611 llamas, collected 1998 2017 in the Quimsachata Experimental Station Instituto Nacional de Innovación Agraria (INIA) Peru. Parameters for Non-linear growth curves estimated by...
Background: Eimeriosis causes inflammation of the intestinal mucosa, leading to excessive mucus, epithelial shedding, and bleeding. It affects newborns offspring aged 2 3 weeks, causing 80% diarrhea cases 43.3% mortality in between 1 months. This study evaluated prevalence parasitic load Eimeria its effect on hematological parameters blood biochemistry (albumin, globulin total protein) alpacas. Methods: Fecal samples were collected by jugular venipuncture from 42 alpacas months at two time...
From a physiological-behavioral perspective, it has been shown that fish with higher density of black eumelanin spots are more dominant, less sensitive to stress, have feed intake, better efficiency and therefore larger in size. Thus, we hypothesized genetic (co)variation between skin pigmentation patterns growth exists is advantageous rainbow trout. The objective this study was determine the relationships BW breeding population We performed analysis traits including dorsal color (DC),...
Abstract Twenty‐four new microsatellite markers were developed for genome mapping and population genetics studies in rainbow trout ( Oncorhynchus mykiss ). The amount of polymorphism, percentage heterozygosity ability each marker to amplify genomic DNA from other salmonids recorded. Seven observed be duplicated the by containing more than one allele homozygous (clonal) fish.
Trout production is a growing activity in recent years but requires new alternative sources of feed to be sustainable over time. The objective this research was determine the apparent digestibility coefficient (ADC) dry matter (DM), organic (OM), crude protein (CP) and digestible energy (DE) kañiwa (Chenopodium pallidicaule Aellen), kiwicha (Amaranthus caudatus L), quinoa Willd), beans (Phaseolus vulgaris L.), sacha inchi, (Plukenetia volubilis L) jumbo squid (Dosidicus gigas) meal juvenile...
Several Creole cattle biotypes can be found in the Andean highlands, and most of them are considered as being risk extinction. The main aim present study was to perform a phenotypic characterization highlands using bio-morphometric measures zoometric indices. Individuals from three different (Black ‘Negro’ (n = 57), Colour-Sided ‘Callejón’ 20), Brindle ‘Atigrado’ 18)) an experimental research center located Peruvian were enrolled study. In total, seventeen morphometric parameters evaluated...
The goal of this study was to predict the body weight Corriedale ewes using machine learning (ML) algorithms. Fourteen measurements (BM) and six different models were used. Body (BW) BM: wither height (WH), rump (RH), thoracic perimeter (TP), abdominal (AP), foreshank length (FSL), fore-shank width (FSW), (FSP), tail (TW), (TPe), hip (HW), loin (LWi), shoulder (SW), forelimb (FL), (BL), collected from 100 between 1.5 2 years old Illpa Experimental Centre National University Altiplano in...
Background: The fibre characteristics of fleece weight (FW), mean diameter (MFD), coefficient variation (CVMFD) and common phenotypic correlations between them Huacaya alpacas (Vicugna pacos) breed, were estimated on 959 one-year-old animals, under extensive rangeland management conditions. Methods: Samples taken 2005 2018 (male female), two coat colors (white brown), at the Toccra CEDAT-DESCO Alpaca Development Center (Arequipa, Perú). Model developed an they included year, sex color their...
Background: The textile use of llama fiber, achieved through genetic improvement, selection and management, shows great potential for producing high-quality clothing fabrics; providing an alternative income to highland residents who raise llamas. aim this research was determine the fiber medullation white Ch´aku Q´ara color varieties Llamas (Lama glama) from communities Macusani district, Puno Peru. Methods: A total 88 varieties, including males females, age milk teeth two teeth, were used....
Abstract Background The protein source from fish meal is very important in trout feeding, but it expensive and scarce. Alternative nutrient sources are required to achieve sustainability as production rapidly grows Peru. objective of this research was determine the proximate chemical composition apparent digestibility coefficient (ADC) dry matter, organic crude protein, fat, digestible energy hydrolyzed sheep (HSS) alpaca (HSA) skins juvenile rainbow trout. Methods A total 450 fishes were...
