The Effects Of Feeding Brown Midrib Corn Silage Compared To Conventional Corn Silage In High Producing Dairy Cows, Erick Mitchell Mendonca

Dairy Science

The objective of this study was to determine if supplementing Brown Midrib Corn Silage into a high cow feed ration could improve digestibility in the rumen, add savings into the feed ration, and improve milk production. Beginning in June of 2012 two hundred high producing Holstein cows were selected from Johnny Mendonca & Sons Dairy in Tulare, Ca to estimate the difference between feeding Conventional Corn Silage compared to Brown Midrib Corn Silage. This test trial was conducted over the span of 4 months and was hypothesized by the author. To achieve this, the author conducted three analyses to determine …

Generating A Nutritional Dairy Cow Ration Based On Green Waste Out Of San Luis Obispo County, Nicole Mendoza

Dairy Science

The objective of this literature review was to assess the accessibility and utilization of waste like products for inclusion into the dairy ration in San Luis Obispo County. With feed prices continually rising, alternatives to the very expensive feedstuffs should be continually explored. In this review, papers based on grocery store waste, viticulture waste, Cal Poly waste, and crop waste were explored to determine the feasibility of including these products into the dairy ration economically. Aspects evaluated were availability, nutrient composition, storing and handling and a viability of undertaken this system to supplement dairy cattle feeding. As a result it …

Loggerhead Shrike (Lanius Ludovicianus): Species Conservation Assessment, Melissa J. Panella

Nebraska Game and Parks Commission: Publications

The primary goal in the development of at-risk species conservation assessments is to compile biological and ecological information that may assist conservation practitioners in making decisions regarding the conservation of species of interest. The Nebraska Natural Legacy Project recognizes the Loggerhead Shrike (Lanius ludovicianus) as a Tier I at-risk species. Here, I provide some general management recommendations regarding Loggerhead Shrikes. However, conservation practitioners will need to use professional judgment for specific management decisions based on objectives, location, and site-specific conditions. This resource provides available knowledge of Loggerhead Shrikes that may aid in the decision-making process or in identifying research needs …

Increasing California Dairy Exports To Japan And South Korea, Kristina Soper

Dairy Science

The opportunities for increasing exports of California dairy products to the Japanese and South Korean markets were determined by identifying current obstacles in the California dairy industry and determining the characteristics of consumers in the Japanese and South Korean markets. As the largest milk-producing state and the supplier of 7.5% of total U.S. dairy exports, California’s economic activity greatly affects the rest of the nation and the world. The trends in the California dairy industry include increasing total milk production and per-cow milk production, a diminishing number of total dairy operations, and a rising number of large dairy operations. These …

Neutering Dogs: Effects On Joint Disorders And Cancers In Golden Retrievers, Gretel Torres De La Riva, Benjamin L. Hart, Thomas B. Farver, Anita M. Oberbauer, Locksley L. Mcv Messam, Neil H. Willits, Lynette A. Hart

Endocrinology Collection

In contrast to European countries, the overwhelming majority of dogs in the U.S. are neutered (including spaying), usually done before one year of age. Given the importance of gonadal hormones in growth and development, this cultural contrast invites an analysis of the multiple organ systems that may be adversely affected by neutering. Using a single breed-specific dataset, the objective was to examine the variables of gender and age at the time of neutering versus leaving dogs gonadally intact, on all diseases occurring with sufficient frequency for statistical analyses. Given its popularity and vulnerability to various cancers and joint disorders, the …

The Impact Of Gut Passage By Binturongs (Arctictus Binturong) On Seed Germination, Christina P. Colon, Ahimsa Campos-Arceiz

Publications and Research

Binturongs (Arctictis binturong) are the largest of Asian civets and, due to their highly frugivorous diet, are expected to play an important role in seed dispersal processes. To study the effect of binturong gut passage on seed viability, we fed 10 captive binturongs with fruits of longan (Dimocarpus longan), papaya (Carica papaya) and chiku (Manilkara zapota), collected the seeds they defaecated, and planted these to determine seed germination rate and time. Of the defaecated seeds, 90.4% passed through binturong gut intact in under nine hours, and 99.4% passed in under 33 hours. Chiku seeds had the highest germination rate (35.7% …

Walking Distance And Performance Of Drylot Developed Beef Heifers Following Being Moved To A Grazing Situation, G.A. Perry, E.L. Larimore, J.A. Walker

South Dakota Beef Report, 2013

Research has shown that heifers moved from a drylot to grass after AI have decreased weight gains and pregnancy success compared to heifers developed on range. This effect could potentially be due to inexperience in a specific grazing environment, which could result in greater time spent exploring a new environment. In this study beef heifers were moved from a drylot to spring grass at two different times and their activity compared. Heifers in a drylot walked less than heifers grazing spring forage. However, following being moved to spring forage heifers that had been adjusted to grass for about a month …

"Beef: The Real Health Food", Peter Ballerstedt

Forage Symposium at the Kentucky Cattlemen’s Convention

The 2010 Dietary Guidelines for Americans recommends restricting our intake of saturated fat to less than 7 percent of calories, and our cholesterol intake to less than 300 mg per day (less than two eggs). They promote the use of low-fat milk and lean meat, and the use of “meat substitutes” in school lunches. These recommendations are consistent with the official dietary policy that began in 1977 with the release of the first Dietary Goals for the United States by the United States Senate Select Committee on Nutrition and Human Needs. These guidelines were not justified by the then-available science. …

Pasture Finishing Beef Opportunities In Kentucky, Greg S. Halich

Forage Symposium at the Kentucky Cattlemen’s Convention

Beef cattle were routinely finished locally in Kentucky before the 1950’s, primarily on pasture with some grain and by-products from distilleries. Cattle were typically born, raised, and finished on the same farm, sent to a local butcher, and the meat sold in nearby communities and cities. This all changed after the Second World War as grain and transportation costs decreased dramatically in conjunction with the establishment of supermarket chains that required a large, steady supply channel. The combined effect of these changes made finishing in large centralized locations more economical. Over the next couple of decades the finishing industry consolidated, …

The Effect Of Handler Personality Type On Feedlot Cattle Behavioral Responses, H. Franzky, R. Pritchard, J. Trenhaile

South Dakota Beef Report, 2013

The ability to readily identify individuals that may have a greater innate ability to handle cattle in a low stress manner would be useful in feedlots and on ranches. This study was conducted to determine whether handler personality type would be a useful tool to predict stockman abilities. To accomplish this, 3 cattle handling exercises were created to observe human‐cattle interactions. A scoring system was developed to investigate cattle handling proficiency based on cattle behavioral responses. Handler personality type was classified using two assessments. Some cattle handling exercises did not differentiate handler personality types. Introverted handlers tended to have higher …

Comparison Of Two Different Methods To Harvest Drought‐Damaged Corn, W.C. Rusche, J.A. Walker

South Dakota Beef Report, 2013

Two methods of harvesting drought‐stressed corn as large round bales were compared in this study. Three acres of drought‐stressed corn were cut and either baled as high‐moisture bales and wrapped in plastic (BALEAGE), or allowed to completely dry and baled with a conventional large round baler (DRY). Core samples were analyzed for moisture, CP, ADF, NDF and in vitro NDF and DM digestibility. Samples from the BALEAGE treatment were lower in CP than those from the DRY treatment. Concentrations of ADF and NDF did not differ between BALEAGE and DRY. Dry matter and NDF digestibility were also similar between the …

The Real Dirt On Biosolids As Soil Amendments, Eton Codling, Ann Perry

Agricultural Research Magazine

The U.S. Environmental Protection Agency (EPA) estimates that more than 60 percent of dry biosolids—treated wastewater solids that can be recycled or stored—are applied to land, composted, or used to cover landfills. The biosolids have been processed to kill pathogens, and EPA strictly regulates biosolid use to ensure the materials don’t harm the environment, human health, or animal health.

Farmers who follow pre- and post-application management regulations can obtain permits to use biosolids for amending fields where food and feed crops are grown. Now, research by an Agricultural Research Service scientist is helping to clarify the long-term effects that biosolid …

With Hot Air Treatment, Bacteria Fly The Coop, Rosalie Marion Bliss, Mark E. Berrang

Agricultural Research Magazine

While being transported in hauling coops on trucks, poultry that have been colonized with bacteria such as Campylobacter can contaminate, through fecal shedding, pathogen-free poultry. Those pathogens can also be passed on to the next group of birds during the next trip, and so forth, unless the cycle is broken.

That’s where Agricultural Research Service microbiologists Mark Berrang and Richard Meinersmann and colleague Charles Hofacre at the University of Georgia in Athens come in. The team has reported a treatment that reduces poultry cross-contamination from transport-cage flooring.

Campylobacter are foodborne pathogens that can be present in raw or undercooked poultry. …

Going Beyond The Barnyard To Stop Stable Flies, David B. Taylor, J.J. Zhu, Sandra Avant

Agricultural Research Magazine

Livestock producers may not be able to see the difference between stable flies and other flies at a distance, but they can definitely see the stable flies’ effect on their cattle as the animals stop grazing and bunch together to minimize the number of bites they’re getting.

Stable flies are among the most important arthropod pests of cattle in the United States. Their painful bites can reduce milk production in dairy cows, decrease weight gain in beef cattle, and reduce feed efficiency.

Generally, insecticide sprays are used to help keep stable flies off animals, especially their legs, where the flies …
