In countries where donkeys are used for work, they are slaughtered at the end of their useful working life and meat is destined for human consumption. This study was carried out to evaluate the mineral composition of donkey carcass meat. Meat was obtained in Donkey Fair 2016 at Mexico State, minerals were analyzed by Atomic Absorption Spectxophotometry, Ca, Na, K, Fe, Zn and Cu, and P content by colorimetry. Data obtained in mg/100g were： Ca, 7.95; Na, 48.75; K, 353; Fe, 3,95; Zn, 3.17; Cu, 0.19 and P, 227. Analysis revealed that donkey meat has a low content of Ca, but it is good in P as well as K. In conclusion donkey meat is a good source of minerals requested for human health.展开更多

The authors present new empirical evidence showing that, as expected, maize prices in Mexico dropped until 2006 and have experienced a process of convergence with USA prices, and maize imports from the USA have increased. However, despite lower prices, maize production in Mexico has trended upward since 1992, two years before the beginning of NAFTA＇s implementation. Based on the heterogeneity of maize production in Mexico, three possible explanations are proposed to explain this unexpected outcome： government supports to big commercial farmers in the agriculturally rich North of Mexico; the persistence of maize production by subsistence farmers; and to a lesser degree, increasing yields on some irrigated maize farms. We finish the paper by drawing lessons from the experience of Mexico for other Less Developed Countries.展开更多
