The objective of this study was to evaluate the effect of three levels of cull pinto beans (CPB) on animal performance, energy balance, and digestibility of hair ewes during pregnancy-lactation. One hundred and sixty-eight Pelibuey ewes were used (105 multiparous and 63 primiparous). Seven ewes of each type were randomly assigned to each of the 24 pens. Then, the twenty-four pens were randomly assigned to one of three treatments. Treatments were assigned on DM basis at: 0 g kg-1 of CPB in the supplement; 250 g kg-1 of CPB in the supplement; and 500 g kg-1 of CPB in the supplement. Data was analyzed by using the PROC MIXED of SAS. Lamb birth and weaning weight were also evaluated with the GLM procedure of SAS. All variables were analyzed as a completely randomized design. No differences among treatments were observed for body weight, body condition score, non-esterified fatty acids, and body weaning weight. During late pregnancy, dry matter intake was different among treatments, but it was similar during lactation. Body birth weight was different among treatments and showed a quadratic effect. At day 30 of lactation, a treatment effect was found for digestibility of dry matter (DM). At the end of lactation, digestibility of crude protein was different among treatments. In day 60 of lactation, differences among treatments were found for digestibility of neutral detergent fiber. Due to equal ewe performance among treatments of CPB and its low cost, its use is recommended in hair ewe feeding for these productive stages: 500 g kg-1 DM of the supplement during pregnancy and 400 g kg-1 DM during lactation.

Según el inventario realizado por la Red de Ornamentales, México es uno de los países más ricos en recursos genéticos y cuenta con 4 220 especies usadas como ornamentales o con potencial de ser introducidas a la horticultura ornamental. Una de ellas es Sprekelia fomosissima conocida como Lirio Azteca que crece de manera silvestre en el Distrito Federal, Estado de México, Morelos y Puebla, entre otros estados. México no ha desarrollado su producción, debido en gran medida al desconocimiento de sus bondades hortícolas tanto por productores, como por comercializadores y consumidores finales. En el mercado internacional es comercializada en algunos viveros de Europa y Estados Unidos de América, por ello se deduce que tendría posibilidades comercializarse en el mercado nacional. Este estudio tuvo como objetivos evaluar el nivel de conocimiento, percepción y disposición para comprar y vender Lirio Azteca por parte de consumidores potenciales deplantasornamentalesenviverosdelasciudadesdeAtlixco, Puebla y Cuautla, Morelos, así como divulgar su importancia y aprovechamiento como planta ornamental mexicana. Se aplicaron 357encuestas durante los meses de abril y mayo de 2013. El Lirio Azteca como recurso nativo mexicano fue de gran interés para 91.7% de los encuestados, lo que nos permite sugerir que de utilizarse campañas que destaquen la importancia de las plantas ornamentales nativas podría incrementarse su conocimiento, conservación, así como su uso en jardines y áreas verdes de México y el extranjero, buscando su aprovechamiento sustentable.
