Endocrine Control Of Ovulation And Coordination Of Fetal And Uterine Interrelationships In Dairy Cattle, Jillian Fain

All Dissertations

Assessing pitfalls in reproductive efficiency of dairy cattle is often confounded by milk production, animal health, energy balance, and animal management practices, among others. Methods to reduce inefficiencies are classified in the following studies as maternal endocrine management, conceptus recognition, and uterine environment. The goal was to derive some insight into the mechanisms pre and post conception that can alter rates of pregnancy establishment. The initial study ascertained the ability to reduce progesterone (P4) dominance through additional PGF2-alpha (PGF) supplementation on efficiency of timed artificial insemination (TAI) in the Ovsynch® program. The single PGF animals received the standard Ovsynch® protocol …

A Literature Review On Crossbreeding In Dairy Cattle, Philip Owens

Dairy Science

The objective of the literature review was to determine whether or not crossbreeding is a profitable and a viable option for the dairymen of today by reviewing the literature and experiments that have been conducted throughout the world by today’s dairy professionals and leaders. The Dairy market today is increasingly competitive and more and more dairymen are considering crossbreeding to decrease health costs and increase profitability. Price premiums from cheese plants are given to milk producers for high components like protein and fat. In recent studies done by universities and research facilities around the world, results have found promising numbers …

W151-Bulk Tank Milk Quality Parameters, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

Bacteria in milk, whether originating from the cow or from the environment, significantly impact the quality of dairy products and therefore consumer acceptance. Bacteria produce heatstable enzymes that can damage milk fat and milk protein. These enzymes are not affected by pasteurization and continue to cause damage in the final dairy product. High bacteria levels in raw milk result in off-flavors, bitter flavors, rancidity and reduced shelf life. The Pasteurized Milk Ordinance specifies safety standards of Grade A milk to protect public health, not to maximize product quality and shelf life. The PMO only sets limits on somatic cell count …

W150-Using Milk Somatic Cell Count Information, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

The level of mastitis infection in a dairy herd can have a significant impact on herd profitability. Losses due to mastitis include decreased milk production, increased treatment costs, discarded milk, premature culling, death, decreased genetic potential, decreased reproductive performance, load rejection due to violation of somatic cell counts (SCC) or antibiotic residues and loss of milk quality premiums (3, 9, 12). Most producers easily relate clinical mastitis with these losses. However, subclinical (or hidden) mastitis may actually cause more losses in a herd than clinical mastitis. Since the animal does not exhibit typical symptoms of the disease, the problem is …

W149-Bulk Tank Milk Quality, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

Who is responsible for the safety and quality of dairy products? Dairy producers? Processors? Retailers? Consumers? In fact, all of these parties – from farm to fork – share in this responsibility. What starts as a high-quality product on the farm can be ruined somewhere along this chain. However, a poor-quality, inferior raw product leaving the farm cannot be transformed into a safe and high-quality product for the consumer. Despite technical advances in milk processing, the safety and quality of dairy products is still determined on the farm. Pasteurization does provide a certain level of safety, but is not the …

W148-Milk Quality And The Tennessee Quality Milk Initiative, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

According to records, in 1995, there were more than 1300 dairy farms in Tennessee. In 2007, the number declined to fewer than 600 dairies (9). There are several reasons for this mass exodus from the dairy industry in Tennessee: low milk prices, shortages of qualified labor, high feed costs, high fertilizer costs, high fuel costs, etc. In addition, many dairy producers in Tennessee and in the Southern Region are at risk of losing their milk market due to below average milk quality. Milk quality continues to be a topic of intense debate in the dairy industry. Dairy producers in the …

Utilization Of Distillers Grains Form The Fermentation Of Sorghum Or Corn In Diets For Finishing Beef And Lactating Dairy Cattle, S. Al-Suwaiegh, K. Fanning, R. J. Grant, C. T. Milton, Terry J. Klopfenstein

Department of Animal Science: Faculty Publications

Beef finishing and dairy lactation experiments were conducted to evaluate the nutritional value of distillers grains (DG) from sorghum or corn fermentation, in both wet (35.4% DM) and dry (92.2% DM) form (dairy trial only). In the finishing experiment, 60 yearling steers were used in a completely randomized design with three diets that were fed for 127 d: 1) control diet with 86% (DM basis) dry-rolled corn and no DG; 2) 30% of ration DM as wet corn DG in place of dry-rolled corn; and 3) 30% of ration DM as wet sorghum DG in place of dry-rolled corn. All …

Pb1598-Managing Intake Of Lactating Dairy Cows, The University Of Tennessee Agricultural Extension Service

Animals/Livestock

Lactating dairy cows must consume large quantities of dry matter (DM) to provide the nutrients needed to maintain high levels of milk production. The consequences of low dry matter intake (DMI) are lower peak milk yields, lower total milk production, excessive loss of body weight and poor reproductive performance. Research has shown a two pound increase in milk production for each pound increase in DMI. As milk production continues to increase, management of DMI becomes more critical.
