Effects of Commercial Feed Additives on Growth Performance and Gut Microbiota of Nursery Pigs
… the dynamic changes of gut microbiota in weaned pigs fed commercial feed additives. Chapter II was used to evaluate the effects of organic acid mixture on growth performance and gut microbiota of weaning pigs. This study demonstrated that the inclusion of 0.035% (SBA0.035) or 0.070% (SBA0.070) …

Effect of a Fermented Yeast Product on the Gastrointestinal Tract Microbial Diversity of Weaned Pigs Challenged With Salmonella Enterica Typhimurium Dt104
… microbial diversity and growth performance of pigs before, during and after an oral challenge with Salmonella. Pigs (n= 40) were weaned at 21 d of age, blocked by body weight (BW) and assigned in a 2Ã 2 factorial arrangement consisting of diet (control or 0.2% XPC) and inoculation (broth or …

Effects of Spray-Dried Porcine Plasma (SDPP) Administered as an Oral Gavage on Indicators of Health, Welfare, and Performance in Pigs Transported After Weaning
… weaned and then immediately transported. Weaned pigs fed starter diets containing SDPP display improved growth performance. The objective of this study was to determine effects of pre-weaning SDPP on indicators of health, welfare, and performance in transported weaned pigs. Pigs were assigned to …

Effect of Sensory Additives on Sow Lactation Performance, Subsequent Reproductive Performance, and Nursey Pig Performance
… to entering the lactation room, and again at weaning. The sows were blocked by parity, and then allotted by BW at d 110 to Control or 0.075% sensory additive (Luctamax® SowVive, Lucta S.A., Spain). Experimental diets were offered upon entry to the lactation room and fed through weaning. Feed …

Biogas production from novel substrates
… from 38 ± 2.0 L CH4 kg−1 VS for pig slurry (weaning pigs) to 805 ± 57 L CH4 kg−1 VS for used cooking oil (UCO). However the selection of the best preforming feedstock in terms of C:N ratio or BMP yield alone is not sufficiently adequate. A total picture has to be created which includes C:N …

Characterization of creep feeding and its subsequent effects on immune response, scouring index, and performance of weanling pigs
… the pattern of creep feed consumption of nursing pigs and the effect of creep feeding - from 10 d to weaning at 28 d - a 20% crude protein corn-soybean meal and dried whole whey diet (REG, 9 litters) containing 1.0% chromic oxide for detection of creep feed consumption, or the same diet with 2.7% …

Immune response to and pathogenesis of porcine epidemic diarrhea virus
… diarrhea (PED) virus causes effusive diarrhea in pigs of all ages and high mortality among pre-weaning pigs. The PED virus (PEDV) is one of several important swine pathogens, which causes significant economic losses to the swine industry. The first outbreak of PED in the United States occurred in …

Detection and description of influenza a virus transmission in commercial weaned pigs in Illinois, USA
… challenges of environmental stressors, such as weaning, transportation, comingling, diet change, and environmental temperature change. At the same time, the immune system of mammals at this age is particularly vulnerable since maternally derived immunity is waning while simultaneously …
