The Effects Of Implementing Cow Cooling For Oostdam Dairy: Benefits From Milk Production, Feed Intake, And Reproduction, Mark Oostdam Mar 2014

The Effects Of Implementing Cow Cooling For Oostdam Dairy: Benefits From Milk Production, Feed Intake, And Reproduction, Mark Oostdam

Dairy Science

Heat stress has a major effect on management decisions for a dairy operation because of the decrease in the cows productivity. Dairy cattle loose efficiency of economic production due to lower milk yields and decreased pregnancy rates. Milk loss due to heat stressed cows in California averages a loss of 293 kg of milk/cow/year(St.-Pierre et al., 2003), and with milk prices reaching record highs, dairies are losing out on increased revenue opportunity. Increases in reproductive infertility from heat stress also affect revenue for a dairy operation by reducing conception rates (Hansen 1997) and pregnancy rates, which ...

A Business Model For The Small-Scale, Start-Up, Organic Jersey Dairy, Jim Moreda Mar 2013

A Business Model For The Small-Scale, Start-Up, Organic Jersey Dairy, Jim Moreda

Dairy Science

To determine the financial feasibility and stability of starting a small-scale organic jersey dairy in Northern California, given the changes and restrictions that must take place in all aspects of production while operating organically. Using a unique combination of ownership and borrowing, I have created a business model made to appropriately fit the organic dairy system, addressing every area of the operation whether it be business or animal related. Through experience, reviews, and research of organic techniques allowable to apply, I was able to reveal and identify specific areas of husbandry and financing in which I would need to excel ...

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 ...

A Business Plan For A Custom Dry Cow Transition Facility And A Calf Ranch, Landon Joseph Fernandes

Dairy Science

In recent economic times the dairy industry has witnessed historic lows in milk price and historic highs in feed prices. As a result many dairies have been forced out of business or have found other ways to diversify in order to offset the accumulated debt from dairying. One possible way a dairy can minimize debt is by sending its transition cows to custom transition cow management facility from dry-off through freshening. This management facility would give optimal care and attention to these cows to ensure metabolic and post calving health issues are minimal and that cows are returned to the ...

Exporting United States' Whey Products To The Chinese Market, Rebecca Mellema

Dairy Science

The objective of this research project was to determine the potential for the increase of U.S. whey exports to the Chinese market. The research was gathered from various locations including the United States Dairy Export Council as well as Euromonitor International. From this research the amount of whey that the US produces was compared with the amount of whey that China imports, then analyzed to determine the increased amount that can be exported by the US to China. An analysis of the current and historical situation for dairy products in China was also included to help determine the market ...

Formation Of Cull Cow Program For The Artificial Insemination Class, Brian O. Medeiros

Dairy Science

Cal Poly’s “Learn by Doing” philosophy is one of the great traits that the University holds. However it is this philosophy that is also one of the most expensive and hardest to maintain. “Production agriculture majors use more dollars per unit than any other major in the entire college,” as Dr. Golden stated during his talks about herd cut backs. Never the less the College of Agriculture prides itself on supplying knowledgeable and experienced students to the industry that supports it so much. One of the amazing classes that are offered at the university is the Dairy Science Artificial ...
