Dietary effects on pig health
… because they provide physiological activities to pigs to improve their health and performance by modulation of microbial populations in the digestive tract and/or immune system. The 6 experiments described in this dissertation were conducted to evaluate whether specific dietary factors can be …

Studies of pig social groupings
… aspects of the social environment of the pig and how manipulation of this environment through dynamic grouping affects the well-being of the animal. The broad objectives were to better understand the process of group formation and the importance of social stability within groups of pigs. …

Evaluation of pig brain developmental patterns and the influence of dietary polar lipids on pig development
Pigs have been strong preclinical models especially in research examining human nutrition and brain development due to their similarities to humans in gastrointestinal development and brain morphology. As such, the neonatal pig has been suggested to be a great model for the neonatal human and due …

Folate Metabolism in the Guinea Pig
… [3',5',7,9-2H folic acid to normal guinea pigs, p-acetamidobenzoate (major product) and p-acetamidobenzoyl- L-glutamate (minor product) were found in the urine. No radioactive folate was excreted except at very high doses when trace amounts of folic acid appeared, or after pre-treatment of …

Effects of phytase and mycotoxin control strategies in nursery pig diets and determining finishing pig lysine requirements
… One experiment using a total of 360 nursery pigs was used to determine the effect of increasing phytase on nursery pig growth performance and bone ash characteristics. Two experiments using a total of 4,223 pigs were used to determine the optimal dietary standardized ileal digestible (SID) …

Welfare issues in Italian heavy pig production
… and focuses on welfare issues in Italian pig production. This sector is characterized by animals (heavy pigs) slaughtered for dry-cured products at a minimum of nine months and 160 kg (compared to 110-115 kg of other EU systems). The first set of studies investigated the feasibility of …

Putting Lipstick on a PIG: Modeling Pine Island Glacier (PIG) Shear Margin Collapse with Compressive Arch Failure and Observations
Pine Island Glacier (PIG) drains 10\% of the West Antarctic Ice Sheet and has undergone rapid change in the observational record, contributing to uncertainty in sea level rise projections. The Pine Island Ice Shelf (PIIS), which provides a key buttressing force that slows the flux of ice across the …

Effect of colostrum supplementation on baby pig performance
… on the performance and immune response of baby piglets. In Exp. 1, 301 newborn pigs (Line 600 × 241; DNA, 1.48 kg) were used in a 21-d study. Pigs were weighed and allotted to one of three treatments at 6-h of age in a randomized complete block design with 23 replications (litters) per …

Genetic linkage of multiple modifications in the pig
… an efficient system(s) to precisely modify the pig genome and to develop a system(s) that would link multiple modifications, both a gene knockout and additional transgenes. There were three main topics that were evaluated: 1) Phic31 recombinase-mediated gene stacking in pigs, 2) the effect of …

Factors Influencing Early Embryonic Development in the Pig
… 1 muM and 3 muM) had no developmental effect on pig embryos, however pig embryos cultured with 3 muM daidzein may improve blastocyst formation over control embryos. Further studies will be required to determine whether higher levels of these phytoestrogens affect embryonic development.

Utilization of Soy Protein by the Young Pig
… protein diet for providing nutrients to young pigs weaned at three to four weeks of age. Soy protein sources were shown to limit feed efficiency when compared to a milk protein, i.e., casein. Cornstarch reduces feed intake and gain in comparison to lactose in the diet. Removal of the soluble …

Factors influencing in vitro maturation of pig oocytes
… of estradiol-17$\beta$ on in vitro maturation of pig oocytes. Cumulus oocyte complexes (COC) were obtained by aspiration of 2-5 mm follicles. The oocytes were cultured for 42 hours at 38.5$\sp\circ$C in mTCM-199 supplemented with LH, FSH, follicular fluid, fetal calf serum and estrous gilt serum, …

Sulfur amino acid nutrition of the young pig
… sulfur amino acid (SAA) nutrition of the young pig. Pigs were ad libitum fed in all experiments. A methionine (Met)-deficient feather meal-corn-soybean meal-dried whey basal diet (20% protein, 3250 kcal ME/kg, 0.19% Met, 1.00% cystine (Cys), 0.11% choline) was used to determine the Met and SAA …
