Mycotoxicoses in domestic livestock: toxicity of ergot alkaloids in domestic poultry and fusariotoxins in beef cattle

Creator:: Roberts, Heaven Le A.
Abstract:: Mycotoxins are food-borne toxins produced by molds which are commonly found on animal feeds of economic significance. Toxic doses of these compounds vary widely across livestock species, and even within a species when considered across all stages of development and production. This variation is due to the wide range of...

Antioxidant Effects of Blackberry Pomace on the Health of Transition Dairy Cows

Creator:: Estenson, Kaelyn A.
Abstract:: Blackberry pomace (BBP), a byproduct from juice processing, is often disposed of in landfills. We propose BBP as an antioxidant-rich feed supplement for transition dairy cows. To explore the effects of BBP on antioxidant status, 24 multiparous dairy cows (5 Holstein and 19 Jersey) were assigned randomly to one of...

Salmonella and other Enterobacteriaceae in dairy cow feed ingredients and their antimicrobial resistance

Creator:: Kidd, Riam S.
Abstract:: Antimicrobial resistant Enterobacteriaceae might be introduced into dairy cows through the consumption of feeds and the microbes may eventually enter the human food supply. Thirty-two farms were selected at random from 43 commodity feeding dairy farms. Of the 32 farms selected, 12 farms agreed to participate in the study. In...

Daily and alternate day supplementation of urea of biuret to ruminants consuming low-quality forage

Creator:: Currier, Thomas A.
Abstract:: Data is limited evaluating infrequent supplementation of urea or biuret to ruminants consuming low-quality forage (<6% crude protein). Therefore, a series of experiments were designed to compare the effects of daily (D) and alternate day (2D) supplementation of two non-protein nitrogen (NPN) sources (urea or biuret) to ruminants consuming low-quality...

Growth and carcass merit of purebred Jersey steer calves finished on grain-based diets at two different energy levels

Creator:: Tschida, Garrett L.
Abstract:: Purebred Jersey steers are often overlooked for beef production due to the perceived poor growth and production. Currently dairy persons marketing their steer offspring are receiving minimal compensation due to lack of demand by beef feeders and a saturated veal market. Twenty purebred Jersey steers were used to evaluate lifetime...

Locally grown alternative feed ingredients in turkey diets

Creator:: Sulaiman, Kurdman Mohammed Ali
Abstract:: In recent years, small poultry producers have been interested in finding an alternative for corn and soybean for a variety of reasons. Health concerns related to either naturally occurring isoflavones (phytoestrogens) or their genetically modified organism (GMO) status are the primary considerations behind this trend. Secondly, the recent high prices...

Nutritional strategies to improve the reproductive performance of beef females

Creator:: Cappellozza, Bruno Ieda
Abstract:: In the first set of studies, 2 experiments evaluated the influence of supplement composition on ruminal forage disappearance, performance, and physiological responses of Angus × Hereford cattle consuming a low-quality, cool-season forage (8.7 % CP and 57 % TDN). In Exp. 1, 6 rumen-fistulated steers housed in individual pens were...

Management of stockpiled forages and optimal use of supplements by beef cattle while consuming low-quality forages

Creator:: Suverly, Norman A.
Abstract:: Three studies were conducted to evaluate: 1) rotationally grazed forage for late-summer stockpiling; 2) effects of lactation on self-fed supplement intake; and 3) influence of cow age on hand-fed supplement intake. For the first study, treatments consisted of non grazed, 2X and 3X grazed. Crude protein of forage grazed 3X...

Development of microparticulate feeds and methods to improve acceptability of artificial diets by blue spotted goby larvae (Asterropteryx semipunctata)

Creator:: Clack, Brendan W.
Abstract:: An acceptable microparticulate diet for marine fish larvae may be defined as an artificial diet that contains, retains, and delivers the required nutrients to support survival and growth. Factors affecting ingestion rate of prey items by fish larvae include environmental factors such as light intensity, prey/background contrast, possible chemical cues,...

Puberty development and reproductive performance in beef heifers fed rations supplemented with Oregon by-product feeds

Creator:: Oswald, Keely E.
Abstract:: In the majority of management scenarios, it is imperative that beef replacement heifers calve at two years of age. In order to achieve this goal, yearling heifers should reach 60 to 65% of their mature body weight by 13 months of age. Feed costs represent 75 to 80% of the...
