Kansas Agricultural Experiment Station Research Reports
We have investigated the potential for using hydrated lime to form protective matrices with oil-rich feeds, such as flaxseed, to increase the incorporation of omega-3 fatty acids into meat. Dolomitic lime is mixed with ground flaxseed, water is added, the mixture is blended in a high-speed turbulizer, and the resulting material is then dried to form a granular matrix. During the manufacturing process, a portion of the hydrated lime becomes recarbonated. This recarbonated matrix is ruminally stable, which prevents rumen microbes from converting polyunsaturated oils to saturated fats. Additional recarbonation occurs in the rumen due to exposure to high concentrations …

Evaluating The Effectiveness Of Transport Media On Shiga Toxin-Producing E. Coli Serotypes, Nicholas W. Baumann, A. West, Randall K. Phebus
Kansas Agricultural Experiment Station Research Reports
One of the key issues involved in accurately testing beef and the environment for the presence of specific bacteria, particularly pathogens such as Shiga toxin-producing Escherichia coli (STEC), is maintaining the viability of the microorganisms when transporting samples from the field to the laboratory. This process may take up to three days when considering collection, shipping and laboratory preparation times. Allowing the target bacteria to increase or decrease in numbers during transit is undesirable, so samples must be kept chilled and the media used for transport must offer a stable but non-nutritive environment. Three commonly used non-selective transport media were …

As the world's population continues to expand, demand for food animal products is also increasing; therefore, efficient production is vital. Implants and beta-adrenergic agonists such as Zilmax (Merck Animal Health, Summit, NJ) improve average daily gain and feed efficiency in feedlot cattle. Use of these growth technologies also increases hot carcass weight and muscle mass. Although use of implants and Zilmax increases efficiency of beef production, these products also negatively affect meat quality characteristics such as marbling and tenderness. Some research reports conclude that wet aging meat for extended periods of time can alleviate tenderness issues caused by exogenous growth …

A total of 1,267 pigs (PIC 337 × 1050; initially 58.3 lb) were used in a 120-d study. Before initiating the trial, pigs were fed a common diet for 9 d containing 188 ppm Cu from tribasic copper chloride (TBCC). On d 0, pens of pigs were allotted to 1 of 8 dietary treatments in a randomized complete block design with 26 to 27 pigs (similar number of barrows and gilts) per pen and 6 pens per treatment. Treatments were arranged in a split-plot design. Whole-plot treatments were 2 levels of the estimated standardized ileal digestible lysine (SID Lys) requirement …

A total of 294 pigs (PIC 327 × 1050, initially 14.1 lb BW) were used in a 31-d trial to evaluate the effects of increasing levels of two different zinc sources on nursery pig growth performance. Pigs were weaned at 21 d of age and were fed pelleted diets for the first 7 d and a mash diet for 24 d of the 31-d trial. Each treatment had 7 replicate pens with 7 pigs per pen. The 6 experimental diets were: (1) a control diet; (2) a diet with 500 ppm of Zn from Zinco+; (3) a diet with 1,500 …
