Optimization Of Conditions For Heat Pretreatment And Enzymatic Predigestion Of Ddgs For Pigs, Kevin Jerez-Bogota
Optimization Of Conditions For Heat Pretreatment And Enzymatic Predigestion Of Ddgs For Pigs, Kevin Jerez-Bogota
Electronic Theses and Dissertations
The high fiber content of corn dried distillers’ grains with solubles (DDGS) can limit its utilization in swine diets. Pretreatment with heat and enzymatic predigestion of whole stillage (WS; slurry material that is dried into DDGS) can alleviate negative effects of dietary fiber and can improve digestive and fermentation characteristics of the feedstuff. However, optimal time and temperature of the heat pretreatment of WS, and best enzymes for predigestion of WS have not been identified. Experiments were conducted to identify optimal conditions for heat pretreatment and multienzyme predigestion of WS for pigs. First experiment was conducted to identify optimal temperature …
Flower Visitation In Relation To Pollen And Nectar Nutrition: Implications For Pollinator Habitat And Conservation, Megan E. Leach
Flower Visitation In Relation To Pollen And Nectar Nutrition: Implications For Pollinator Habitat And Conservation, Megan E. Leach
Electronic Theses and Dissertations
Pollination of both wild and crop plants is at a crossroads; honey bee populations are experiencing losses at a higher rate than ever before, and some native bee species are declining in abundance to the point of being listed as endangered species. A few examples of these threats include pesticide exposure, habitat loss, and climate change. In response to bee population declines, conservation efforts have been initiated to increase habitat quality for bees by planting pollinator reservoirs or gardens. Plants provide nutrition to bees in the form of pollen and nectar. Several studies have shown links between higher nutritional quality …
