ABSTRACT.
Income and household size for food were estimated for Hispanic households in the United States. Engel curves for nine main food groups and three meat subgroups were estimated by different econometric methods using a semi-logarithmic model. The results inidcate that the Hispanic demand for food is relatively income inelastic but more responsive to household size. Income transfer programs such as Women, Infants and Children certificates and Food Stamps appeared to be positively associated with milk and fruit consumption relative to non-recipients.
RESUMEN.
En este estudio se estimaron las elasticidades de la demanda de alimentos para hogares hispanos en los Estados Unidos, respecto al ingreso y al tamaño del núcleo familiar. Se construyeron curvas de Engel para nueve grandes grupos de alimentos y tres distintos tipos de carnes, usando un modelo semi-logarítmico, mediante diferentes métodos econométricos. Los resultados obtenidos indican que la demanda de alimentos por parte de los hogares hispanos es relativamente inelástica con respecto al ingreso, mostrando una mayor respuesta a variaciones de tamaño del núcleo familiar. Adicionalmente, se encontraron evidencias de que algunos programas de transferencia de ingreso como Women, Infants and Children y Food Stamps, estarían positivamente asociados a un mayor consumo de lácteos y frutas, comparados con hogares que no reciben estos beneficios. |

Abstract:
Ipomoea carnea, a swainsonine containing plant, is known to cause a neurologic disease in grazing livestock in Brazil and other parts of the world. To better understand the relative toxicity and nutritional content of I. carnea we investigated swainsonine, calystegine, and crude protein concentrations in leaves of I. carnea on a monthly basis for one year in northern and northeastern Brazil. Swainsonine concentrations were detected at concentrations that could potentially poison an animal throughout the year although there was some variation between months. At one location swainsonine concentrations were generally the highest during the rainy season or the months immediately following the rainy season. Total calystegine concentrations were similar to those reported previously while crude protein concentrations are similar to those found in other Ipomoea species and are such that they may explain why I. carnea becomes desirable to grazing livestock as forage becomes limited during the dry season. |
