Male calves and culled cows of dairy cattle are used for beef production. However, unlike beef breeds, the genetics of growth performance traits in dairy breeds have not been extensively studied. Here, we performed a genome-wide association study (GWAS) on Holsteins ( = 5,519), Jerseys ( = 1,231), and Red Dairy Cattle ( = 4,410) to identify QTL for growth traits. First, a GWAS was performed wit...

OBJECTIVE We evaluated the epidemiology of antimicrobial resistance in enterococci from animal farms and the potential relation of resistance to antimicrobial use. METHODS Enterococci from faecal samples from 18 beef cattle, 18 dairy cattle, 18 swine, 13 chicken, and eight turkey farms were prospectively evaluated over a 6 year period from 1998 to 2003. RESULTS We evaluated 1256 isolates of...

Gastrointestinal nematodes (GIN) are a major health and economic risk factor in ruminant production in organic and conventional farms (Thamsborg et al., 1999). Fattening of organic beef cattle (OBC) on pasture is an emerging area for organic farmers in Switzerland, which partly compensates the declining development in dairy production. So far, there are no data available about the parasitic sta...

To elucidate current status of fasciolosis and eurytremosis in beef cattle of Japan, inspection data of Tokyo Metropolitan Shibaura Slaughterhouse where beef cattle were shipped from all over Japan were analyzed, and questionnaire to farmers was conducted to assess the relationship between recognition of the disease occurrence in one's own farm and attention to the diseases. The occurrence of f...

Knowing whether or not a food contains gluten is vital for the growing number of individuals with celiac disease and non-celiac gluten sensitivity. Questions have recently been raised about whether beef from conventionally-raised, grain-finished cattle may contain gluten. To date, basic principles of ruminant digestion have been cited in support of the prevailing expert opinion that beef is inh...

The number of meat recalls has increased markedly in recent years. This research examines the impact of beef and pork recall announcements on nearby daily live cattle and lean hog futures market prices, respectively. Results indicate medium-sized beef recalls that are of serious health concerns have a marginally negative impact on short-term live cattle futures prices. However, results are not ...

Neospora caninum is one of the most important causes of abortion in cows. The occurrence of N. caninum infection in beef and dairy cattle has been reported worldwide, and in most provinces in Canada. The objective of this review is to summarize our current understanding of N. caninum in dairy and beef cattle for Canadian bovine practitioners. The review covers the life cycle of the agent, its m...

The Food Safety Commission (FSC) of Japan, established in July 2003, has its own initiative to conduct risk assessments on food stuffs known as "self-tasking assessment". Within this framework, the FSC decided to conduct a risk assessment of beef and beef offal imported into Japan from countries with no previous BSE reports; thus, a methodology was formed to suit to this purpose. This methodolo...

Digital dermatitis is a polybacterial disease process of dairy and beef cattle. Lesions are most commonly identified on the plantar aspect of the interdigital cleft of the hind limbs. Treponema spp are routinely present in large numbers of active lesions. Lesions are painful to the touch and can result in clinical lameness. The infectious nature generally results in endemic infection of cattle ...

Beef knuckles (n = 160) were obtained from source-verified cattle finished on 30% wet distillers grains plus solubles enriched with varying levels of alfalfa hay, corn silage, or corn stalks based on NDF. Our objectives were to determine if roughage inclusion, in conjunction with wet distillers grains plus solubles and cattle location affects beef flavor. Data from this study indicate type and ...
