Introduction: The future success of the beef industry will be largely determined by our ability to meet consumer demands. Consumers want beef to be safe, consistently tender, palatable, free of outside fat, easy to prepare, and reasonably priced compared to other proteins. The dramatic increase in the number of cattle marketed through grid pricing structures is an example of the beef industry r...

Real-time, B-mode ultrasonography provides the opportunity to improve the methods of evaluation of ovarian function and diagnoses of pregnancy in beef cattle. Determination of the sex of a fetus early in pregnancy (d 55 to 85) and verification of embryo viability by monitoring fetal heartbeat are unique methods involving ultrasound scanning. These techniques and a method for evaluating the tech...

This cross-sectional study evaluated risk factors associated with farm-level bovine leukemia virus (BLV) seropositivity in 563 dairy and 490 beef farms throughout Japan. Twenty randomly selected cattle on each farm were serologically tested, and farm epidemiologiocal information was obtained through face-to-face interviews. Due to the large number of zero-prevalence dairy and beef farms, data a...

Previous surveys of wild ungulates indicate that the liver fluke, Dicrocoelium dendriticum, was rare in the Cypress Hills area of southeastern Alberta. However, 41 of 59 wapiti (Cervus elaphus) sampled during the 2003 and 2004 hunting seasons from this region were infected, with 7 hosts containing >1,000 worms. Prevalence and mean intensity were similarly high in sympatric beef cattle and mule ...

The objective of this study was to evaluate the effects of replacing dry ground corn with crude glycerol on intake, apparent digestibility, performance, and carcass characteristics of finishing beef bulls. A completely randomized block design experiment with 25 d for adaptation and 100 d for data collection was conducted, in which 3,640 Nellore bulls (367 ± 36.8 kg; 18 ± 3 mo) were blocked by b...

Beef and pork are two commonly consumed meats that can be processed in many different ways. The primary reason for processing beef and pork is to improve consumer acceptability and convenience of preparation, and to extend shelf life. To achieve this, processing usually accomplishes the following. 1. Remove bones, if applicable. 2. Make connective tissue less objectionable, by removal of extrem...

BACKGROUND Fasciola hepatica is a parasite with a significant impact on ruminant livestock production. Previous studies in north-west Europe have described its geographical distribution and determined potential predictors of fasciolosis using geographical information system (GIS) and regression modelling. In Sweden, however, information about the distribution of fasciolosis is limited. This stu...

Nutritional disorders associated with both forage and feed consump­ tion can have a large impact on the profitability of beef cattle operations. Forages are an important component of beef cattle production systems in Arkansas. Most cow­calf and stocker cattle enterprises in Arkansas rely heavily on forage­based nutritional programs. Forages are used for both livestock grazing and hay production...

Subtropical regions such as the South-Eastern United States as well as places like Brazil are characterized by average year round temperatures of 27 ̊C (80°F). In the summer months temperatures can rise to 43°C (110°F). These temperatures are usually associated with high humidity and low forage quality and it is imperative that beef cattle in these regions be able to withstand these warm, harsh ...

The present study was performed to investigate the infection status of intestinal parasites in pigs and beef cattle in rural areas of Chungcheongnam-do, Korea. From November 2009 to April 2010, a total of 241 fecal samples of pigs and beef cattle (136 and 105, respectively) were examined by direct smear and centrifugal sedimentation methods. The overall positive rates of intestinal parasites am...
