Previous research demonstrated significant variation in the prevalence of Salmonella in peripheral lymph nodes (LNs) of feedlot cattle and cull cows, with greater prevalence in feedlot cattle. Therefore, we performed experiments to investigate whether these differences in Salmonella prevalence in subiliac LNs are due to, or influenced by, breed, which in many respects is a proxy for the product...

Bovine respiratory disease (BRD) is a common endemic disease among North American feedlot cattle. BRD can lead to significant economic losses for individual beef cattle feedlot producers through mortality and morbidity. With promising new management and technology research that could reduce BRD prevalence, this study evaluates the potential impacts of a reduction of BRD in the US beef cattle fe...

As a beef cattle nutritionist, two things have been drilled into to me from early on: 1) the cheapest way to feed the cow is to let her “harvest” her own feed by grazing, and 2) corn is the cheapest source of energy for fed cattle. However, fluctuations in corn and land prices in more recent years have raised questions regarding the truth in these old adages. The objectives of these proceeding ...

Canadian beef consumption is approximately 31 kg per annum, or a third of all meats consumed. Beef is a nutrient-rich food, providing good quality protein, vitamins B-6 and B-12, niacin, iron, and zinc. However, animal fats have gained the reputation of being less healthy. The identification of the anticarcinogenic effects of beef extracts due to the presence of conjugated linoleic acid (CLA) h...

Introduction During the 1980s, the beef slaughtering industry became increasingly concentrated. In 1980 the four largest packers slaughtered 36% of fed cattle nationally and marketed 53% of boxed beef. By 1989 the four largest firms slaughtered approximately 69% of the fed cattle and marketed more than 80% of the boxed beef (Purcell 1990a; Lambert 1990). Concentration is even higher in some reg...

Minerals can be divided into two main categories, 1) macro-minerals and 2) micro or trace minerals. Macro minerals are minerals that are needed/required in relatively large amounts in comparison to micro or trace elements which are needed/required in relatively small amounts. In general macro minerals are required at concentrations greater than 100 ppm of the diet and are often expressed as a p...
