摘要：In the farming sector, the cattle activity is one of the main ones where 1,5 million units of production with different degrees from technologies and that it occupies around 200 million hectares and contributes 40% of the PIB of this sector. The State of Sonora is the second in extension in the country and exported in 2009-2010 the amount of 281.785 heads of cattle with a surface of 15,5 million hectares and the value of the cattle production was of 11'396,951 thousands of pesos. Within this surface it is carried out the young and operation of cattle of intensive way that occupies great land surfaces standing up predominating the maintenance of cattle and increase of yearling calves. Another exploitation system is the artificial prairies with rye-grass or bermuda fattens as well as it in corrals where the cattle confines itself and with balanced and prepared feeding daily gains of weight over 1.1 are obtained kg/day. For the analysis of yield of the lot of 100 yearling calves in the modality of repasto of yearling calves financial tools like the determination of the capital of work that was by the amount of $ 508,650, the relation benefit-cost that was of 1.12. Another tool was the sensitivity analysis taking as reference the final from period and combined weight with the sale price by kilogram still on that was of 28.00 by kg. The balance point also was determined throwing a result of 194 kg by yearling calf, that is to say, with this weight the producer recovers its production costs, the financier and obtains a final gain; for the calculation of the financial cost the interbank interest rate was taken like reference from balance to which a differential of 8 points was added to him to be in annual 12.90%. With these result obtained, the producer will be able to make the decision to continue with the modality of repasto of yearling calves and to take them to the export market or to confine them in artificial prairie or corral of gets fat.
