RESUMO
Antecedentes: el conocimiento de la producción y disponibilidad de carne vacuna y porcina en los territorios nacionales es de vital interés en el campo de la nutrición humana, porque la disponibilidad se constituye en un factor primordial en la elección y consumo de este alimento entre la población. Objetivo: efectuar un análisis comparativo relacionado con el suministro de carne vacuna y porcina en países de Suramérica desde 1961 hasta 2019. Materiales y métodos: para el análisis de la información se utilizó el modelo lineal general empleando la técnica multivariada de la varianza con contraste canónico de tipo ortogonal, análisis de clúster y estadística descriptiva exploratoria de tipo unidimensional. Resultados: Argentina presentó diferencia altamente significativa en la disponibilidad de carne vacuna para su población, respecto a los demás países de Suramérica (p<0,0001). Paraguay es el país con mayor disponibilidad de carne de cerdo. El país de menor participación de fuentes cárnicas vacunas y porcinas es Perú. Conclusiones: existe una gran divergencia entre algunos países de Suramérica en la cantidad de suministro cárnico proveniente del vacuno y del cerdo.
Background: The production and availability of beef and pork meat in the countries of South America is of vital interest in the field of human nutrition because availability is a primary factor in the choice and consumption of this food among the population. Objective: To carry out a comparative analysis related to the supply of beef and pork in South American countries in the last six decades, from 1961 through 2019. Materials and Methods: For the analysis of the information, the general linear model was used using the multivariate variance technique (MANOVA) with canonical contrast of orthogonal type, cluster analysis and exploratory descriptive statistics of a one-dimensional type. Results: Argentina presented a highly significant difference in the availability of beef for its population, compared to other countries in South America (p <0.0001). Paraguay is the country with the highest availability of pork. The country with the least sources of beef and pork is Peru. Conclusions: There is a great divergence among countries of South America in the amount of available meat supply from beef and pork.

Análise de MediaçãoRESUMO
Brazil is the world's largest broiler meat exporter. Health control, knowledge and technology, as well as the natural aspects of the country are pointed out as the keys for the success of that product in the market. Brazilian broiler production grew significantly in the last decade; it creates jobs and has a significant social role in Brazilian economy. This study aimed at evaluating the Brazilian broiler meat supply chain from 2000 to 2010 using the social network analysis (SNA). Data from governmental and private sources were organized and analyzed. The focus of this study was the broiler production supply chain segment involving the hatchery, the broiler farm, the feed mill, the processing plant, and the government. The inputs considered were one-day-old chicks, pullet, feedstuff, and the infrastructure; and the outputs were broiler meat and taxes paid. The software UCINET was applied for calculating the structural attributes and indicators of the network. Results showed a relatively disorganized network in 2000 with the strongest tie between the farmer and the processing plant. The structural organization of the network improved until 2010. The density of the ties in the broiler meat production network increased steadily from 2000 to 2010 within a vertical cohesive supply chain structure. The success of Brazilian broiler meat production is attributed to the abundance of land, fertile soil, favorable climate, and the effort and investments in research and development by innovative companies in the last few years. The results of the present study showed that Brazilian broiler production evolved positively in the last ten years, and it was weakly influenced by international challenges.
