Book Description
"This book contains over 300 offered papers in addition to 4 papers from invited speakers presented at the 52nd International Congress of Meat Science and Technology, held in Dublin, Ireland, from 13-18 August 2006. Under the theme of harnessing and exploiting global opportunities, areas covered in the congress included meat quality encompassing genomics and biotechnology, animal production and production systems, muscle biology and biochemistry; meat safety, meat processing and packaging technology, consumer topics and meat and health. A new approach this year was to address specific hot topics important to the industry and meat scientists, in particular, electrical stimulation and new instrumental methods for evaluation of meat quality characteristics. These proceedings reflect the truly global nature of meat research and give an insight into the current research issues for the industry."

The Effects of Grain Processing Method, Wet and Dry Distiller's Grains with Soluble and Roughage Level on Performance and Carcass Characteristics of Finishing Cattle

Book Description
A series of five trials were conducted to evaluate grain processing, distiller's grains inclusion in finishing diets, interactions between distiller's grains and dry-rolled corn (DRC) or steam-flaked corn (SFC), efficacy of removing roughage in the presence of distiller's grains and the digestibility of distiller's grains in steam-flaked and dry-rolled corn diets. The first trial was designed to determine the optimum flake density of SFC in beef finishing diets. Diets consisted of corn flaked to densities of 360, 411, or 462 g/L. Observed improvements in mill production would support increasing flake density; however numerical decreases in animal performance offset economic benefits of increased productivity. The second trial was conducted to evaluate optimum levels of sorghum wet distiller's grains in finishing diets. Crossbred yearling steers were fed diets containing DRC or SFC and levels of distiller's grains were 0, 10, 20, or 30% of diet dry matter. Distiller's grains can effectively replaced a portion of the corn in finishing diets, but their nutritional value was greater in DRC diets than in SFC diets. In trial 3, crossbred heifers were fed diets containing SFC with 0% DDG and 15% corn silage (CS), 25% DDG and 15% CS, or 25% DDG and 5% CS. In trial 4, crossbreed heifers were fed diets similar containing DRC or SFC with 0% DDG and 15% CS, 25% DDG and 15% CS, or 25% DDG and 5% CS. Results indicate that roughage levels can be reduced in feedlot diets containing DDG with no adverse effects on performance or carcass quality. The fifth trial was a metabolism study conducted to evaluate the digestibility of DDG in beef cattle. Treatments consisted of DRC with 0% DDG, DRC with 25% DDG, SFC with 0% DDG, and SFC with 25% DDG. There were no significant grain processing by distiller's grain interactions observed in main effects. In conclusion optimum flake density was 360 g/L, feeding distiller's grains has a greater value in DRC diets vs. SFC diets, roughage level and type are important in formulating finishing diets, roughage can be reduced when feeding distiller's grains, and ruminal ammonia, and pH are decreased and ruminal lactate is increased when feeding DDG and SFC.

Book Description
Three methods of forage-finishing (pasture, silage, hay) for beef cattle were used to evaluate growth performance, carcass traits, meat quality, and fatty acid composition relative to grain-finished beef. Two hundred steers (100 Angus, 100 Hereford) were equally allocated (based on size) to 2 locations, evaluating alfalfa or grass forages as alternatives to grain. Growth performance and carcass traits were greater for grain-finished steers. Forage-finishing increased (P 0.02) concentrations of alpha-linolenic acid and total omega-3 fatty acids vs. grain-finishing. A trained taste panel found no difference (P 0.05) in tenderness between forage-and grain-finished beef. Beef flavour intensity was greater (P

Effects of Source and Level of Dietary Roughage and Ractopamine (Optaflexx) Supplementation on Growth Performance, Carcass Characteristics and Meat Quality in Beef Cattle

Book Description
A high moisture corn/soybean meal-based finishing ration was used to examine the effects of roughage source (corn silage, alfalfa hay), level of dietary roughage (8, 16, 24%), and ractopamine supplementation (none, Optaflexx) on growth performance, carcass traits, and beef quality for finishing 108 steers and 24 heifers (initial BW = 308 kg). Cattle were allocated by gender to 12 management regimen subclasses. Optaflexx (trade name for ractopamine hydrochloride) was fed over the last 28 d on feed with cattle marketed after common days on feed. Growth performance (ADG, feed intake, and feed efficiency) and carcass traits were assessed on an individual animal basis. A primal rib and semitendinosus (ST) muscle from each animal were processed at the University of Guelph Meat Laboratory for carcass and meat quality evaluations. Tenderness was determined using shear force assessment of product aged 7, 14, and 21 d. Average daily gains were similar (P > 0.27) across main effects while use of corn silage as the roughage source decreased (P 0.001) dry matter intake and improved (P 0.001) feed efficiency compared to feeding alfalfa hay. Roughage level and beta agonist supplementation did not affect (P 0.13) dry matter intake or feed efficiency. When the last 28 days on feed were examined, Optaflexx supplementation increased (P 0.001) weight change, ADG, and improved feed conversion, while DMI remained unchanged (P 0.373). Carcass traits including hot carcass weight, grade fat, longissimus muscle area, marbling, and body composition as assessed by rib dissection (% lean, fat, bone) were not affected (P 0.14) by roughage level, source, or use of Optaflexx. Fat partitioning and liver abscess scores were unaffected (P > 0.09) by source and level of roughage fed, and use of Optaflexx. Source and level of dietary roughage did not affect color (P > 0.21) or shear force (P > 0.20) values for longissimus (LM) and semitendinosus (ST) steaks. Lower DMI and better feed conversion can be achieved using corn silage as the roughage source, while inclusion of up to 24% roughage in finishing diets may not negatively impact gains, carcass characteristics or beef quality. Beef producers may be able to increase amounts of roughage in the diet to lower cost of production without compromising growth performance and carcass and meat quality.
Impact of Zymannase on Growth Performance, Carcass Characteristics, Fat Quality and Processed Meats in Finishing Barrow Fed 30% Dried Distiller's Grains with Solubles

Book Description
As ethanol production continues to increase, so does the use of dried distiller's grains with solubles (DDGS) in swine diets. The effects of high concentrations of DDGS on growing/finishing pigs has caused problems with growth performance, carcass characteristics, fat quality, and processed meats. This is due to the high fiber content and elevated levels of unsaturated fats in of the diet. Since DDGS fiber is a complex carbohydrate pigs cannot digest, the use of carbohydrases to improve growth performance is reasonable. Carbohydrase enzymes may be able to help improve fat quality, however the effect of carbohydrase enzymes on fat quality has not been thoroughly researched and the effect on processed pork products has not been examined. Therefore, the objective of these experiments was to evaluate the effects of two carbohydrase enzymes on growth performance, carcass traits and quality, fat quality, and two types of processed pork products (fresh bratwurst and ring bologna) from pigs fed a diet containing 30% DDGS. Pigs were fed a one of two corn/soybean meal/DDGS diets, the only difference being the enzyme group received a combination of two carboghydrase enzymes at the expense of corn. While the pigws were alive growth performance was documented. After the pigs were humanely slaughtered, carcass traits and quality where documented. There was no effect of enzymes on any growth performance or carcass values recorded except for a slight change in the color of the loin. There was no effect of diet on the fat quality. There was a minimal effect on the ring bologna. The biggest influence of enzyme was on the bratwurst. Enzymes had a negative effect on bratwurst quality over time on some qualities. However, other qualities of the bratwursts were positively affected. These results suggest carbohydrase enzymes in a diet containing 30% DDGS does not significantly affect growth performance or carcass characteristics of growing/finishing barrows. However, they do indicate that more research is needed to better understand the effect of carbohydrase enzymes on fat quality and more importantly, processed pork quality.
