The effect of multinutritional blocks (BMN) based on agro-industrial residues on the production and composition of bovine milk in a tropical region of Peru was evaluated. For the elaboration of the BMN, agro-industrial residues from the processing of rice (rice polishing) and coconut (cake) were used. Twelve native cows were used to graze in paddocks with Brachiaria brizantha distributed in two groups (A and B) of six animals during two periods of 21 days each. Two treatments were established: T0 (grazing without supplementation) and T1 (grazing plus supplementation with BMN). During the first period, group A received T1 and group B received T0, while in the second period the reverse was done. Daily milk production (kg/day), milk composition (protein, fat, lactose, total solids, %) and the level of urea in milk (mg/100 ml) were measured. The change-over design was used to analyze the res...

La colangiografía retrógrada endoscópica (CPRE) se ha convertido en un procedimiento esencial en el diagnóstico y tratamiento de las enfermedades biliopancreáticas. Las complicaciones de este procedimiento son infrecuentes, pero potencialmente graves, siendo necesario saber reconocerlas para la aplicación del tratamiento adecuado. Presentamos el caso clínico de una mujer de 79 años que desarrolló un enfisema subcutáneo, neumotórax bilateral, retroneumomediastino, retroneumoperitoneo y neumoperitoneo debido a una lesión iatrogénica del duodeno secundaria a una colangiografía retrógrada endoscópica. El diagnóstico precoz de las lesiones iatrogénicas tras la realización de una CPRE determinará el correcto tratamiento de esta complicación, que debe comprender variaciones en la clínica y fisiología del paciente.

Background: Five hundred years ago, goats were introduced to Peru, and since then, they have adapted to different climatic conditions, giving rise to the Creole goat, characterized by showing greater rusticity and better quality in both milk and meat than specialized breeds. Aim: This study aimed to describe the phenotype of the Creole goat in the Highlands of Chincha province, Ica. Methods: A total of 146 females aged >2 years without signs of crossbreeding with specialized breeds from the districts of San Juan de Yanac, San Pedro de Huacarpana, and Chavin were evaluated. Six phaneroptic characteristics, nine morphometric characteristics, and nine zoometric indices were registered. Tables and bar graphs were prepared. The chi-square test was performed to determine the association between districts and phaneroptic variables, ANOVA to identify differences between districts, correlation co...

The purpose of this study is to evaluate the phenotypic characteristics and typification of Creole goats in five localities of the Ayacucho region in south-central Peru. Materials and Methods: Data from 149 goats (25 males and 124 females) were collected, excluding animals under 2 years of age, pregnant, and sick. Seven qualitative characteristics and 11 zometric measurements were evaluated, and then 9 zometric indices were estimated. Results: In the region, goats with composite colors predominated (76.50%). Additionally, supernumerary (24.20%) and divergent teats (22.60%) were observed in females, while males exhibited a scrotal bifurcation (32.00%). The origin of the flock had a significant effect (p < 0.05) on body measurements, as well as on pelvic index, transverse pelvic index, longitudinal pelvic index, compactness index, and load cannon bone index, except for body index (BOI), pr...

This study assessed the prevalence and risk factors associated with gastrointestinal parasite infection in goats in Ayacucho, Peru. Fecal samples were collected from a total of 254 goats from four districts of Ayacucho: Ocaña (89), Colca (76), Pacaicasa (64), and Luricocha (25) during the dry season; recording the location, sex, and age of the animals. The fecal samples were analyzed using the flotation technique in salt and sugar solution, and modified McMaster egg counting techniques for eggs/oocysts (epg/opg) of gastrointestinal parasites. The associations between location, sex, and age with the prevalence of gastrointestinal parasites were analyzed using the chi-square test. Fecal samples showed an overall parasite prevalence of 87.80%. The identified parasites were Eimeria spp. (86.22%), Strongyle type eggs (STE) (65.75%), Skrjabinema spp. (7.87%), Trichuris spp. (3.15%) and Moniez...

Objective: The study assessed the anthelmintic activity of Artemisia absinthium ethanolic extract for controlling gastrointestinal nematodes in goats, both in vitro using infective larvae and in vivo in naturally infected goats under free-grazing conditions in the region of Ayacucho, Peru. Materials and Methods: For the in vitro assay, a larval motility inhibition test was performed on Trichostrongylus spp. infective larvae from goats using three different dilutions: 150, 175, and 200 mg/ml of the plant extract. In vivo efficacy was evaluated through the fecal egg count reduction test (FECRT), which was applied to 15 naturally infected Creole goats in one community. Animals were randomly assigned to 3 experimental groups and treated orally with 600 mg/kg of the plant extract. Fecal samples were collected directly from the rectum on days 0 (pre-treatment) and 7 and 15 post-treatment for e...

Background and Aim: Characterizing local animal production systems is crucial for sustainable livestock development. This study aimed to characterize the diversity of goat production systems in the Highlands of Chincha province, Ica, Peru. Materials and Methods: A structured questionnaire was used to gather data from 82 goat breeders in three districts: San Juan de Yanac, San Pedro de Huacarpana, and Chavín. Factor analysis of mixed data and hierarchical classification analysis were conducted to identify typologies of goat production systems using R version 4.4.2. Results: Four distinct goat production types were identified, primarily differentiated by feeding location and deworming frequency. Type 2 (41.5%) was the most prevalent, characterized by grazing on breeders own land, minimal milk production (<1 liter/day, 91.2%), and a focus on cheese and goat kid sales (70.6%). Breeders were...

OBJECTIVE This study aimed to report the impact of production practices and sanitary management on the prevalence of Neospora caninum (N caninum) and bluetongue virus (BTV) in Creole goats from the tropical dry forest of Utcubamba, Peru. METHODS 354 blood samples were obtained from male and female goats of diverse ages reared under an extensive productive system. The diagnosis of N caninum and BTV was conducted through a commercial ELISA kit (iD.vet) with readings taken on a Bio-Rad iMark microplate reader at 450 nm. Additionally, a survey was conducted with 18 goat producers to categorize them based on social, technical (production, health, reproduction, nutrition, and infrastructure), environmental, and economic factors. RESULTS The overall seroprevalence of N caninum and BTV in goats was 6.21% and 7.06%, respectively, Notably, group II farmers had the highest prevalence rates at 7.69%...

Gastrointestinal parasitism is a health issue in livestock, particularly in non-intensive farming systems. This research evaluated the prevalence and risk factors associated with gastrointestinal helminths in goats from three ecosystems in Peru: the Andean shrubland (Ancash), dry forest (Lambayeque), and coastal valley (Lima). The study used a cross-sectional design, with random sampling of goats from extensive production systems in each ecosystem. A total of 819 fecal samples were collected and analyzed using qualitative and quantitative parasitological methods. Additionally, coproculture was performed to identify infective larvae of nematodes. The FAMACHA© index was used to assess anemia levels, while body condition scores were recorded to evaluate the nutritional status of the animals. The highest prevalence was recorded in the Andean shrubland (74.2%), followed by the dry forest (63...
