Comparison of pig restraint, sampling methods, and analysis on blood lactate concentration

Buzzard, B.L.; Edwards-Callaway, L.N.; Anderson, D.B.; Engle, T.E.; Grandin, T.; Goodband, Robert D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2012-12-07)

The objective of the study was to examine the effects of restraint and blood sampling method on blood lactate concentration (LAC) in pigs. Restraint methods used were snaring or restraint with sorting boards. Blood was ...
Effect of sample size and method of sampling pig weights on the accuracy and precision of estimating the distribution of pig weights in a population

Paulk, C.B.; Highland, G.L.; Haydon, K.D.; Tokach, Michael D.; Nelssen, Jim L.; Goodband, Robert D.; DeRouchey, Joel M.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2012-12-07)

Producers have adopted marketing strategies such as topping to help reduce economic losses from weight discounts, but they are still missing target weights and incurring discounts. We have previously determined the accuracy ...
Effect of sampling method on the accuracy and precision of estimating the mean pig weight of the population

Paulk, C.B.; Highland, G.L.; Haydon, K.D.; Tokach, Michael D.; Nelssen, Jim L.; Goodband, Robert D.; DeRouchey, Joel M.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2012-12-07)

Producers have adopted marketing strategies such as topping to help reduce economic losses from weight discounts at the processing plant. Despite adopting these strategies, producers are still missing target weights and ...
Meta-analysis comparing growth performance, carcass characteristics, and water usage of growing-finishing pigs fed using conventional dry and wet-dry feeders

Nitikanchana, S.; Tokach, Michael D.; DeRouchey, Joel M.; Goodband, Robert D.; Nelssen, Jim L.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2012-12-07)

Fifteen trials were used for meta-analyses comparing the effects of conventional dry (CD) and wet-dry (WD) feeders on growth performance, carcass traits, and water usage of growing-finishing pigs. The meta-analysis indicated ...
Effects of feeder design (conventional dry vs. wet-dry) on growth performance of 45- to 246-lb pigs

Nitikanchana, S.; Tokach, Michael D.; DeRouchey, Joel M.; Goodband, Robert D.; Nelssen, Jim L.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2012-12-07)

A total of 1,253 pigs (PIC 1050 × 337; initially 45 lb) were used in a 104-d study to evaluate the effects of using a wet-dry (WD) or conventional dry (CD) feeder on growth performance of growing-finishing pigs. At the ...
