A Prrs Cap Update On The Regional Control And Elimination Of Prrsv (2011), Raymond R. Rowland R Jan 2011

A Prrs Cap Update On The Regional Control And Elimination Of Prrsv (2011), Raymond R. Rowland R

Kansas Agricultural Experiment Station Research Reports

The control and elimination of porcine reproductive and respiratory syndrome virus (PRRSV) represents one of the most challenging tasks facing the swine industry world- wide. Several factors related to the biology of the virus make disease detection and elimination difficult. Efforts are further hampered by a lack of vaccines that can protect naïve herds from infection. With this in mind, elimination efforts that incorporate existing tools and knowledge are being initiated. The principal focus is at the region level. One example of success is the Stevens County project in Minnesota, which has attained a PRRSV-negative status and has been expanded …

Effects Of Increasing Dietary Wheat Middlings On Nursery Pig Growth Performance (2011), J A. De Jong, Joel M. Derouchey, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz Jan 2011

Effects Of Increasing Dietary Wheat Middlings On Nursery Pig Growth Performance (2011), J A. De Jong, Joel M. Derouchey, Michael D. Tokach, Robert D. Goodband, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A total of 180 nursery pigs (PIC 327 × 1050, initially 25.2 lb BW) were used in a 21-d trial to evaluate the effects of increasing dietary wheat middlings on growth performance. Pens of pigs were balanced by initial BW and were randomly allotted to 1 of 5 dietary treatments with 6 replications per treatment. The 5 corn-soybean meal-based diets contained 0, 5, 10, 15 or 20% wheat middlings. Overall (d 0 to 21), pigs fed increasing wheat middlings had decreased ADG (linear, P<0 .05) and ADFI (linear, P<0 .005), but F/G was not affected by dietary wheat middlings. Despite the linear decrease in ADG and ADFI, the biggest reduction in performance was not observed until wheat middlings increased beyond 15% of the diet. This suggests that in some cases, the slight decrease in ADG with a low inclusion of wheat middlings (<15%) to the diet might be economically justified, so its inclusion needs to be evaluated on an income over feed costs basis.; Swine Day, Manhattan, KS, November 17, 2011

Kansas Agricultural Experiment Station Research Reports

Deoxynivalenol (DON), also known as vomitoxin, was prevalent in the 2009 U.S. corn crop and subsequently present in dried distillers grains with solubles (DDGS), in which DON levels are about 3 times higher than the original corn source. One method shown to reduce DON levels was by increasing moisture and temperature when sodium bisulfite was added to DON-contaminated corn (Young et al., 19874). Therefore, a pilot study aimed first to replicate these results by placing DON-contaminated DDGS in an autoclave (60 min at 250°F) in the presence of sodium metabisulfite (SMB). The study used 6 treatments: (1) control, (2) 0.5% …

A total of 336 finishing gilts (initially 258 lb) were used in a 21-d growth trial to evalu- ate the effects of increasing stocking density on performance of pigs classified in the slower-growing fraction of the pig population. Pens of gilts were blocked to minimize variation associated with barn location and the diet fed for the 14 d prior to the start of this trial. Within each block, pens of pigs were randomly allotted to treatments (6 pens per treatment). Treatments included stocking pens with 8, 12, 16, or 20 pigs per pen, allowing 22.5, 15.0, 11.3, and 9.0 ft2/pig, …

Producers have adopted marketing strategies such as topping to help cut economic losses at the processing plant. Even though producers are implementing these strategies, they are still missing target weights and receiving substantial discounts. To assess this situation, we must first determine the accuracy of sampling methods producers use to estimate the mean weight of the population. The standard sampling procedure that has been adapted by many producers is to weigh a subsample of pigs in multiple pens (i.e., 5 pigs from 6 pens). Using a computer program developed in R (R Foundation for Statistical Computing, Vienna, Austria), we were …
