    • Comparative Susceptibility of Honey Mesquite to Dicamba and 2,4,5-T

      Scifres, C. J.; Hoffman, G. O. (Society for Range Management, 1972-03-01)
      Applications of dicamba controlled about the same percentage of honey mesquite (Prosopis glandulosa Torr., var. glandulosa) as equivalent rates of 2,4,5-T in the Rolling Plains, Coastal Prairie, and South Texas Plains. Combinations of 2,4,5-T and dicamba controlled no more honey mesquite than either herbicide alone. Honey mesquite control was governed by total herbicide applied rather than relative proportions of 2,4,5-T and dicamba in combination. Dicamba was effectively substituted for 2,4,5-T in combinations with picloram. Three-way combinations were no more effective than mixtures of dicamba and picloram or 2,4,5-T and picloram.
    • A Behavioral Study of Angora Goats on West Texas Range

      Askins, G. D.; Turner, E. E. (Society for Range Management, 1972-03-01)
      Behavior of four Angora goats was studied in sixteen observation periods for four seasons on a west Texas range. The goats consistently fed during two definite daylight feeding periods: (a) early morning, and (b) late afternoon to dusk. Bedding generally occurred whenever darkness became evident and little or no feeding activity was observed between that time and daybreak. The four goats differed somewhat in their behavioral activities, but were remarkably similar in their vegetation preference. Seasonal difference seemed to have an important effect upon both vegetative preference and behavioral activities./Cuatro cabras fueron marcadas y sus actividades fueron observadas a través del año. Las cabras mostraron un patrón de actividades sistemático a través del año. Empezaron el día levantándose y rumiando por un tiempo breve, seguido por una época de pastoreo de tres horas, luego por 30 minutos de descanso y después pastoreo otra vez hasta mediodía. Tomaron agua y descansaron en la sombra durante medio día hasta tres horas antes de la puesta del sol. Comieron otra vez por tres horas o sea hasta en la noche cuando tomaron agua otra vez y comieron sal, seguido por descanso por toda la noche. Aproximadamente de 34.4% de su tiempo de pastoreo fué con gramíneas y 65.6% fué ramoneo. Parece ser que las estaciones del año tienen un importante efecto en la preferencia del forraje pastoreado, y las actividades de las cabras.
