Effects Of Glutamine On Growth Performance And Intestinal Development Of Immune Challenged Weanling Pigs Fed Chemically Defined Diets, Steven J. Kitt, Phillip S. Miller, Robert L. Fischer
Nebraska Swine Reports
Glutamine is currently considered a nonessential amino acid for pigs. In this study we investigated whether glutamine is essential during an acute immune challenge. Thirty-six individually housed 20-day old pigs were blocked by location and allotted to one of three purified dietary treatments: 1)contained no L-Glutamine (CON), 2) contained 5% L-Glutamine (GLN), or 3) contained no L-glutamine but was equalized to GLN diet on a nitrogen basis with other nonessential amino acids (AA). Pigs were fed these diets for a 14-day growth assay. On day 7, one half of the pigs from each treatment were injected with 200 µg•kg BW …

Pigs treated alike vary in performance due to their different genetic makeup and to environmental effect we cannot completely control. When a group of pigs is randomly allotted to treatments it is nearly impossible to get an “equal” group of pigs on each treatment. The natural variability among pigs and the number of pigs per treatment determine the expected variation among treatment groups due to random sampling.

Effect Of Post-Cooking Holding Time On Consumer Taste Panel Ratings Of Enhanced Pork Loins, Christian Perversi, Chris R. Calkins, Kent M. Eskridge
Nebraska Swine Reports
Sensory evaluation of food products is a valuable means of learning about their characteristics. Consumer taste panels are regularly used to evaluate properties of meat products such as pork loins. The objective of this research was to evaluate the effect of post-cooking holding time on the taste panel ratings of enhanced pork. The loins used in this project were enhanced with varying percentages (close to 10%) of solutions containing water, salt, phosphates and natural juices or flavors. The loins came from 10 different suppliers and were served in randomly allotted groups of seven, throughout twenty, one-hour taste panel sessions. The …
Omega-3 Fatty Acids And Swine Reproduction - A Review, Duane Reese
Omega-3 Fatty Acids And Swine Reproduction - A Review, Duane Reese
Nebraska Swine Reports
A literature review was conducted to examine the role dietary omega-3 fatty acids may play in swine reproduction. Omega-3 fatty acids are not normally present to any great extent in practical swine diets, but they are increasingly important in human and pet health. Swine nutritionists have focused primarily on the effect omega-3 fatty acids may have on littler size, piglet preweaning mortality, and boar fertility. Feeding omega-3 fatty acids to sows has not generally improved litter size. Piglet preweaning mortality may be improved by omega-3 fatty acid supplementation provided sows are allowed to farrow naturally (without induction). Boar fertility seems …

Do Crowded Pigs Respond To Paylean®?, Mike Brumm, Phillip S. Miller, Robert C. Thaler
Nebraska Swine Reports
Paylean® is a feed additive that improves feed efficiency, daily gain and carcass merit in finishing pigs. Restrictions in space allocation are known to reduce daily feed intake and daily gain. Thus, pigs may not respond as expected to dietary additions of Paylean® if feed intake is reduced due to crowding. A 2 x 2 factorial design was used to examine the potential interaction of Paylean® and space allocation. Experimental treatments were: 1)14 or 19 pigs per pen (8.0 vs 5.9 ft2/pig); and 2) Paylean® for four weeks prior to slaughter (0 or 9 g/T). In this experiment, …

Fatty Acid Composition Of Fresh Pork Bellies -Implications To Bacon Production?, Carmina Robles, Betsy Booren, Roger W. Mandigo
Fatty Acid Composition Of Fresh Pork Bellies -Implications To Bacon Production?, Carmina Robles, Betsy Booren, Roger W. Mandigo
Nebraska Swine Reports
Commercial bacon processors often raise concerns regarding the management practice of frozen storage of the bellies prior to curing and processing for sliced bacon. Deterioration of quality measures is a concern and is usually attributed to freezer storage. A secondary issue, in the production of bacon including those processed from frozen bellies, is the effect of breed and sex of pigs. Therefore, an experiment was conducted to determine the effect of a 15-day frozen storage time, the genetics, and sex of the pig on the quality and fatty acid profile of pork bellies. Frozen storage of fresh pork bellies did …

The Economic Potential Of Methane Recovery: Projected Impacts Of Various Public-Policy Scenarios, Richard R. Stowell, Christopher G. Henry
Nebraska Swine Reports
Economic analyses were performed on anaerobic digestion of manure from swine finishing operations. The main factors considered were facility size (1,000 head; 3,500 head; and 10,000 head) and method of financial support provided (cost-share program, no-interest loans, tax subsidies, and subsidized electrical sales). Installation of a digester system is a significant investment that is currently very difficult to justify economically to Nebraska producers based upon consideration of currently available income and expense estimates, regardless of facility size. Swine finishing operations looking to invest in this technology would benefit most from a no-interest loan or cost-share program – policies that relate …
Case Ready And Enhanced Pork - How Do Ingredients Make Them Work?, Mike Baczwaski, Roger W. Mandigo
Case Ready And Enhanced Pork - How Do Ingredients Make Them Work?, Mike Baczwaski, Roger W. Mandigo
Nebraska Swine Reports
Case ready pork products have grown at a tremendous rate since the early, large scale introductions of the mid 1990’s. Estimates exceed 9 billion pieces in the near future, up from 500 million in 1997 and 1.2 billion in 2000. Estimates are that between 70-80% of the fresh pork at the supermarket is now utilizing two technologies in the case-ready status. These two technologies include enhancement and marination. Enhancement is the application of a solution of water, salt and sodium phosphates, usually approximately a 12% solution. Marination expands the solution with flavor and texture profiles involving additional ingredients. The major …
