Deficiency of selenium (Se) or alpha-tocopherol (E) creates serious health issues in horses. This study evaluated owner supplementation practices and their efficacy at preventing deficiency in a large population of horses. In addition, common clinical signs of horses presenting to a referral institution who had Se and E testing performed...
Mustard and rapeseeds (Brassica sp.) are native to the temperate regions of Europe. They were among the first domesticated crops. Mustard has been cultivated for at least 4,000 years as an oil, spice, and medicinal plant. It has been cultivated not only for seed, but also as a forage, green...
Sorghums (Sorghum bicolor) are warm-season grasses native to Africa. They were introduced into the United States in the 17th century. They are grown primarily under dryland conditions or with limited irrigation in the semiarid
southwest and the Great Plains. Grain sorghums generally are cultivated in areas that are too hot...
Two experiments evaluated nutritional management of late-gestating beef cows to enhance offspring productivity. The objective of experiment 1 was to evaluate the effects of organic and inorganic Cu, Mn, Zn, and Co supplementation to beef cows during late-gestation on performance and physiological responses of the offspring. The objective of experiment...
Assessment of beef cow energy balance
and efficiency in grazing-extensive rangelands has
occurred on a nominal basis over short time intervals and
has not accounted for the complexity of metabolic and
digestive responses; behavioral adaptations to climatic,
terrain, and vegetation variables; and documentation of
the effects of nutrient form and...
The stocking density for chickens can have major impacts on their health and welfare. There is no single correct answer for how many chickens you can house in a specified area, as it depends on the quality of housing. Chickens can tolerate a higher stocking density without major health concerns...
The objective of the present research was to determine, by use of the progesterone receptor antagonist RU-486, whether progesterone by autocrine/paracrine action suppresses phosphatidylinositol hydrolysis, and thus, the production of prostaglandin F2a during the midluteal phase of the estrous cycle in ewes. Two experiments were performed. Experiment 1 consisted of...
Safflower (Carthamus tinctorius L) is a herbaceous annual and a member of the
Asteraceae/Compositae (sunflower) family. It is native to parts of Asia, the Middle East, and Africa. It was grown mainly for its flowers, which were used in making dyes for clothing and food. Today, it is grown mainly...
Sudangrass (Sorghum bicolor L. Moench) was introduced into Texas in the early 1900s and soon became established as an important pasture crop.
After its introduction, many improved varieties were developed. They have greater disease resistance, sweeter stems, less toxic chemical content, and more leaves than previous varieties. This is the...
Alfalfa (Medicago sativa L), called queen of forages, is the most important and productive forage crop in North America. It is the most widely adapted legume known. It was introduced to the western United States in the 1850s, and it is well suited to the dry climates and irrigated soils...
