have emphasized increased production, more milk, faster gains, and greater mature size. Therefore, they have adopted management practices and bred cattle with this purpose in mind. As a result, weights and gains have increased in performance-oriented herds. In many cases, however, increases in profitability have not paralleled increases in production. The systems concept of beef production inco...

Objective: By investigating the effects of feeding Enterococcus faecalis FK-23 preparation to Japanese Black cattle in the late fattening period, this paper discusses the increased value of beef and the feasibility. Method: 10 beef cattle were grouped into the Test Group and the Control Group, 5 beef cattle in the Test Group were fed E. faecalis FK-23 preparation at 8.0 g per day per head. The ...

Concerns are growing over the impact of livestock farming on environment and public health. The livestock industry is faced with the double constraint of limiting its use of natural resources and antimicrobials while ensuring its economic sustainability. In this context, reliable methods are needed to evaluate the effect of the prevention of endemic animal diseases on the productivity of livest...

John M. Marsh (406) 994-5621 [email protected] Prices received by cow-calf producers depend upon many factors including retail beef demand, red meat and poultry supplies, food safety, trade in live cattle and beef, and breeding cattle inventories. In addition, feed grain supplies and prices are important since they impact the cost of gain in cattle finishing. Cost of gain influences feedlot de...

In view of the scarcity of information concerning viral diarrhoea virus (BVDV) infections in beef cattle in Poland, the aim of this study was to evaluate the presence of the BVDV in young beef cattle from selected herds in eastern and south-eastern regions of Poland. The material consisted of 78 sera obtained from beef cattle from 15 farms, aged 6-12 months. The anti-BVDV antibody level in the ...

However, the foundation of a viable beef industry is effective resource management by cattle producers. Unlike most other agricultural enterprises, beef cow owners must manage their herds to make the most profit from the available resources while ensuring the lon...

Bovine abortions due to Neospora caninum infection have been reported worldwide and its economic impact on the beef industry has been acknowledged as a problem. Uruguay has the largest export value of beef per acre in South America. However, no data on the prevalence of N. caninum infection have been available in this country. The objective of this study was to estimate the prevalence and distr...

This review addresses the characteristics and health benefit of highly marbled Wagyu and Hanwoo beef. Marbling of Wagyu and Hanwoo beef has been increased in Japan and Korea to meet domestic consumer preferences. Wagyu and Hanwoo cattle have high potential of accumulating intramuscular fat (IMF) and producing highly marbled beef. The IMF content varies depending on the feeding of time, finishin...

This thesis examines the e ect of horizontal market structure among beef cattle producers on pass-through of international beef prices to local saleyard cattle prices. The measure of market concentration used is the Her ndahl-Hirschman Index ( HHI ). HHIs are constructed using newly-available disaggregated cattle herd size data for 9 regions across the state of New South Wales. A time-invariant...

Each year Shiga toxin-producing Escherichia coli (STEC) are responsible for 2.8 million acute illnesses around the world and > 250,000 cases in the US. Lowering the prevalence of this pathogen in animal reservoirs has the potential to reduce STEC outbreaks in humans by controlling its entrance into the food chain. However, factors that modulate the colonization and persistence of STEC in beef c...
