Sheep raising in the state of Guerrero, México, is a primary activity that is worth about US$3,251,931 annually. The objective of the present study was to evaluate the chemical composition, degradability, nutrient intake, and animal performance of Pelibuey lambs fed on different combinations of maize-soybean silages. Twenty-one combinations of maize silage (MS) and soybean silage (SS) were evaluated at day 45 post-ensiling; in each combination, MS was replaced by 5 % of SS. The 21 combinations were analysed for crude protein (CP) and chemical composition. In order to obtain a statistical criterion of potential treatments for the animal feeding test, a cluster analysis was performed based on the CP contents of all combinations at day 45 post-ensiling. From cluster analysis, four treatments were selected T1 = 100-0 % (MS/SS), T8 = 65-35 %, T12 = 45-55 %, and T16 = 25-75 %. Results indicated that cluster analysis was useful for identifying the potential treatments for animal feeding based on the crude protein content. The dry matter (DM), organic matter (OM), and acid detergent lignin (ADL) contents did not declined significantly (P > 0.05) during the fermentation of silages but CP content decreased from day 0 to 45 post-ensiling. The treatment with the highest estimated microbial crude protein synthesis was T8 and it showed the highest metabolizable energy intake, high feed efficiency with a forage-concentrate ratio of 84:16.

A. (2017) Demografía de brúquidos (Coleoptera: Bruchidae) asociados con Vigna unguiculata (L.) Walp (Fabaceae). Acta Zoológica Mexicana (n.s.), 33(1), 9-17. RESUMEN.Los brúquidos se alimentan principalmente de semillas de leguminosas, entre las cuales se encuentran algunos cultivos de importancia económica como el frijol (Phaseolus vulgaris L.), garbanzo (Cicer arietinum L.), lenteja (Lens culinaris Medik) y tamarindo (Tamarindus indica L.) entre otros, considerando al primero como la fuente principal de proteína en la dieta humana; sin embargo, Vigna unguiculata (L.) Walp, por sus propiedades nutritivas podría sustituir al frijol, pero su principal problema es la presencia de plagas, en particular los brúquidos, los cuales ocasionan pérdidas considerables en postcosecha, por lo que fue necesario conocer los parámetros poblacionales de Acanthoscelides obtectus (Say, 1831), Callosobruchus maculatus (Fabricius, 1775) procedente de dos hospederos diferentes y Zabrotes subfasciatus (Boheman, 1833) alimentados con V. unguiculata por medio de un estudio demográfico bajo condiciones controladas. Los parámetros poblacionales se estimaron con la técnica de tablas de vida de cohorte, la prueba de Log rank (p ≤ 0.05) y las tasas de reproducción e intervalos de confianza con la técnica no paramétrica de Traslape de Intervalos (p ≤ 0.10), para comparar tasas instantáneas de reproducción (r m ), llamada también capacidad innata de incremento. Estos parámetros poblacionales fueron mayores en la emergencia de los adultos y tasas de reproducción de C. maculatus en sus dos modalidades por lo que esta especie puede ocasionar serios problemas cuando se presenta asociado con V. unguiculata; sin embargo, A. obtectus y Z. subfasciatus sólo si no tienen opción podrían alimentarse de V. unguiculata en condiciones de almacenamiento. ABSTRACT. Bruchids feed primarily on legume seeds, which include some economically important crops such as the bean (Phaseolus vulgaris L.), chickpea (Cicer arietinum L.), lentil (Lens culinaris Medik.) and tamarind (Tamarindus indica L.) among others. Whereas the first is the main source of protein in the human diet; Vigna unguiculata (L.) Walp because of its nutritional properties could replace the bean, pests, in particular bruchids, are a major problem and cause considerable postharvest losses. For this reason, it is necessary to determine population parameters of Acanthoscelides obtectus (Say, 1831), Callosobruchus maculatus (Fabricius, 1775)

Kangkong (Ipomoea reptans Poir.) seeds have different colors at harvest due to differences in the seed maturity level, hence, differences in seed quality. Therefore, this study aimed to obtain information about the phenology of flowers, fruits, seeds, and to determine the appropriate heat unit accumulation to reach the seed physiological maturity of kangkong when the maximum seed quality is achieved. The experiment was arranged in a randomized completely block design with one factor. The experimental factor was the seed harvest age consisted of 15 levels, starting from 16 days after anthesis (DAA) or 79 days after planting (DAP) to 30 DAA. The anthesis occurred at 63 DAP. The results showed that the seed physiological maturity of kangkong cv KK02 was achieved at 25 DAA with the characteristics of brownish fruit color, white seeds, and the seeds turned dark brown after drying. At 25 DAA, the seed moisture content was the lowest while the seed dry weight, seed viability, and seed vigor reached their maximum. The heat unit of kangkong cv KK02 at the seed physiological maturity was 1,668.50 °Cd. It is suggested that the kangkong seeds are harvested at 25 DAA with a heat unit of 1,668.50 °Cd.
