The present research aimed to identify the main internal factors (costs, income, techno-economic feasibility and technologic innovation use) which affect the beef cattle activity competitiveness in a complete cycle production system in the state of Rio Grande do Sul. The data was collected during the year of 2008 based on monthly meetings between the months of January and December. Later the data was analyzed in eletronic spreadsheets. The costs were subdivided in disbursed, operating and total costs and the income in category and total. Among the evaluated costs, the land opportunity cost, labor force and animal supplementation with values of 19.9%, 18.3%, 13.6% respectively, can be pointed out in relation to total cost. The main financial and technical indicators commonly used in production systems analysis were calculated. The economic margins (gross, operating and net), as well as the profitability over the net worth were positive which show economic feasibility in the activity. At the same time, technical indicators as the output rate and the productivity/ha showed satisfactory values. Thus it can be concluded that the evaluated internal factors were very competitive for the studied system.

The effects of the live weight of 1,880 lots of calves marketed in 13 auctions in the State of Rio Grande do Sul, Brazil, on the value of final sale per unit of weight were evaluated, as well as the frequency of the lots according to the weight class during the autumn and spring seasons, in the period from 2004 to 2006, was characterized. The data were analyzed by frequency histograms, regression, and correlation analyses. The live weight is one of the characteristics that influenced the price of the calves; however, the magnitude of the effect was higher in years of great demand. A negative correlation was observed between price and weight of the calves in spring, which were results of the offer of heavier animals, due to the season effects or the oldest age of the calves compared to those presented in the autumn. The chain conjuncture of the bovine meat and the prices of other categories have great relation with the prices paid. Therefore, the acquisition of highter or heavier animals in the occasion of the business deal may help in the reduction of the costs represented by the replacement in the production.
