longistrongylus curvispiculum (nematoda: trichostrongyloidea) in free-ranging exotic antelope in texas.longistrongylus curvispiculum was recovered from free ranging sable (hippotragus niger), addax (addax nasomaculatus) and biesa oryx (oryx beisa) on two ranches in central texas (usa). these nematodes represented a small portion of the total abomasal worm burden dominated by haemonchus contortus. female l. curvispiculum easily could be confused with other ostertaginae, but the spicules of the males were diagnostic.19938355363
vertical migration of haemonchus contortus infective larvae on cynodon dactylon and paspalum notatum pastures in response to climatic conditions.observations were made on vertical migration patterns of haemonchus contortus infective larvae on cynodon dactylon (bermudagrass) and paspalum notatum (bahiagrass) pastures under summer climatic conditions typical of east texas. ten thousand h. contortus infective larvae (l3) were introduced to 100 cm(2) subplots of each pasture species within a plot area of 1m(2). subplots were inoculated with larvae by applying them in an aqueous medium to the soil or mat beneath the vegetation. herbage from t ...201020149541
efficacy of albendazole and levamisole in sheep against thysanosoma actinioides and haemonchus contortus from the edwards plateau, texas.lambs naturally infected with thysanosoma actinioides and naturally and experimentally infected with haemonchus contortus were used in a controlled experiment to determine the anthelmintic activity of albendazole as compared with levamisole. the lambs were given 10,000 h contortus larvae 25 to 35 days before treatment, were slaughtered 7 to 9 days after treatment, and were housed on concrete from the time of treatment until slaughter. in lambs given doses of 7.5 mg or 3.8 mg of albendazole/kg or ...19807369618
effects of season and physical condition on the gastrointestinal helminth community of white-tailed deer from the texas edwards plateau.eighty-six adult female white-tailed deer, odocoileus virginianus (zimmermann), collected over a 12-mo period in the texas edwards plateau, harbored six species of nematodes (haemonchus contortus, gongylonema pulchrum, oesophagostomum venulosum, ostertagia ostertagi, cooperia sp., and apteragia odocoilei), and two cestodes (moniezia sp. and taenia hydatigena). the patterns of distribution of the three common species of gastrointestinal helminths (h. contortus, o. venulosum, and g. pulchrum) were ...19854032624
special problems of hair goats.the majority of angora goats in the united states are in texas, although several other states have significant populations. angora goats have unique nutritional requirements, especially for protein, owing to their selection for mohair production. they are typically managed on extensive systems in which nutrition is marginal at certain times of the year. mineral requirements and plant toxicities may vary between regions where angora goats are raised. many toxic plants are unpalatable and a proble ...19902245371
