Assessing Particle Size and the Cost of Grinding
Particle size reduction improves feed efficiency in all stages of the production cycle in pigs. Based on studies by researchers at Kansas State University (KSU), an average particle size of 700 to 800 microns (um) is recommended. However, this recommendation is based on studies conducted using corn-soybean meal based diets. To our...
Interaction of Dietary Energy and Phytase on Performance of Weanling Pigs
Approximately 60 to 80% of the phosphorus (P) in cereal grains and oil seeds is bound to phytate and unavailable to monograstics, including swine. Supplementing swine diets with the phytase enzyme improves P availability and retention. The phytate molecule complexes other minerals, proteins, and starch, however, the research examining the...
Response of Growing-Finishing Pigs to Dietary Energy Concentration
In this trial, feeding lower energy, lower cost diets had no effect on ADG or on loin thickness, but did improve feed efficiency, and reduced backfat thickness. This indicates that lower energy diets may be used to increase net income. This experiment was conducted in an environment of high...
The Effects of Water Availability and Space Allowance on Productivity and Profitability
Reduced floor space allowance for pigs may negatively affect growth performance as a result of competition for feed and water access, especially at later stages of the grower-finisher period. However, kilograms of pork produced per unit of floor space may increase with more pigs per pen, improving overall profitability...
The Interaction Between Pig Density and Dietary Energy on Performance
Dietary net energy and stocking density independently affect performance, feed utilization and profits in the finisher barn. The objective of this experiment was to assess the interactions of stocking density and dietary energy, and determine how these interactions affect net income. When stocking density was increased, the performance of finishing...
Neither Photoperiod nor Time of Weaning Impact Nursery Performance
Weaning, which requires adapting to a new feed source and environment, may result in anorexia and reduced growth in the initial 24 to 48 hours in the nursery. Th is study was designed to determine if altering the photoperiod in the farrowing room and/or if weaning at the end...
Dietary ω-6 to ω-3 Fatty Acid Ratios Affect Protein Deposition in Nursery Pigs
An experiment was conducted to determine if decreasing the dietary omega-6 (ω-6) to omega-3 (ω-3) fatty acid (FA) ratio would affect protein deposition in nursery pigs during a prolonged E. coli lipopolysaccharide (LPS) inflammatory challenge. Following a one week long challenge, six week old piglets fed a lower ω-6:...
Dietary ω-6 to ω-3 Ratio Impacts Nursery Pigs
Results from these experiments indicate that altering the omega(ω)-6 to ω-3 fatty acid (FA) ratio can improve nursery pig performance, and protein deposition, potentially by diverting nutrients away from an unnecessary inflammatory response. Additionally, we found no effects on piglet performance or health by altering the amount without changing the...
Can Bovine Colostrum Mitigate the Post-Weaning Growth Lag?
Bovine colostrum is a good source of nutrients and growth factors, and is very palatable. It was added to the creep feed of piglets in the farrowing room and to the phase one diets immediately post-weaning to determine if it would increase feed intake, and help reduce the impacts...
