(2012-05-12)For several decades, multiple species stocking has been accepted as an effective and efficient practice in the ranching industry of west Texas. Benefits include exploitation of multiple markets, flexibility to adjust to ... -
Effects of various tenderization strategies on non-fed beef palatability and tenderness
(2012-05-12)Effects of exogenous enzyme combinations and a mechanical tenderization method were evaluated by myofibrillar fragmentation (MFI), sensorial attributes and oxidative stability (TBA) of the deep pectoral (PEC: n=120) and ... -
A morphological comparison of Holospira monclovana and Holospira picta (Gastropoda: Urocoptidae) using X-ray computed tomography
(2012-05-12)This study was undertaken to re-evaluate the taxonomic placement of two species of xeric-adapted holospirids from near Monclova, Coahuila, Mexico using techniques unavailable to researchers at the time of the original ... -
Morphological and molecular variation in Townsend's big-eared bat (Corynorhinus townseendii) in West Texas
(2012-05-12)Previous studies of Townsend's big-eared bat (Corynorhinus townsendii) from Big Bend National Park (Brewster Co.) have been limited and inconclusive regarding the expected subspecific identity of specimens from this region. ... -
Effects of isoflavones on reproductive functions of ram lambs
(2012-05-12)A study was conducted to determine if the isoflavones found in soybean‐based proteins were a detriment to ram lamb production and/or rate to puberty. New born Rambouillet and Suffolk ram lambs were randomly assigned either ... -
Effects of soy isoflavones on the attainment of puberty in ewe lambs
(2012-05-12)In humans, diets containing high levels of soy isoflavones have shown to increase circulating estrogen levels. With this increase, early attainment of puberty has been experienced. Although a negative in humans, this could ... -
Changes in intake and nutritional quality of saltcedar
(2012-05-12)Recently weaned Boer-cross (n=20) and Angora (n=6) goats were individually penned and fed increasing amounts of saltcedar. Weight, intake, and water consumption data were monitored. In addition, saltcedar samples were ... -
Maternal influence on juniper consumption in Boer-cross goats
(2012-05-12)The objectives of this study were to determine if maternal influences increased redberry juniper (Junipers pinchottii Sudw.) consumption by goats. Twenty-one Boer nannies were bred to determine the effects of maternal ... -
Feeding specific amino acids to increase redberry juniper consumption by goats
(2012-05-12)Redberry juniper (Juniperus pinchotii Sudw.) is a chemically defended, invasive brush species in western states. Previous research has demonstrated that goats supplemented with escape protein sources will consume a higher ... -
United States policy towards rogue states
(2012-08-10)One of the United States' main security challenges in the post-Cold War era is rogue states. Given that such states are an ongoing security concern, a review and evaluation of U.S. policy towards rogue states will be useful ... -
Effects of GnRH and prostaglandin combined with a short progestin regimen on the synchrony of estrus and ovulation in ewes during the breeding season
(2012-08-10)The lack of effective, consistent synchronization protocols for ewes is a barrier to the use of artificial insemination in sheep. This study compared the estrus and ovulation percentage and window of synchrony of estrus ... -
