Immunologic Evaluation of Ectopic Gestation
<p>Ectopic gestation is an error in the implantation site of the blastocyst. Extrauterine implantation presents a unique environment since the protective features of the uterus are absent. This study is an investigation into the immunoregulatory differences that may develop as a result of a change …

Understanding the effects of maternal undernutrition in early gestation on placental development in late gestation
… which maternal under-nutrition (MUN) during earlygestation permanently alters placental development, the mechanism by whichthis occurs, and whether leptin acts as a mediator.The relationship between the maternal environment and long-term healthof offspring is referred to as the developmental …

Post-Weaning, Early Gestation Sows: Housing and Welfare
… and psychological welfare of post-weaning, early gestations sows in relation to their housing condition. The goal of this study was to observe and compare the behavior of post-weaning, early gestation sows housed in three different housing types: gestation stalls, individual Proposition 12 …

Phenotypic and Functional Characterisation of Hofbauer Cells Across Gestation
… morphology within placental villi changes during gestation; appearing as rounded cells in the first trimester compared to highly elongated and branched cells at full term. Live ex vivo imaging demonstrated that HBC were motile in the first-trimester placenta and sessile by full term. A …

Maternal Age: Influence on Length of Gestation and Birth Weight
… group (CD = 3.37, a = .05) in relation to gestational length. These findings are significant for healthcare providers in rural areas, since much of the previous research had been done in highly urbanized or inner city settings.

Dietary Energy Restriction During Late Gestation in Multiparous Holstein Cows
Multiparous Holstein cows were used to determine the effects of diet, intake, and physiological state on hepatic mitochondrial camitine palmitoyltransferase (CPT) activity. In experiment 1, 30 cows were fed high grain (HG), high fat (HF), or high grain + high fat (HGF) diets from dry-off to …

Consumption of Endophyte Infected Fescue During Gestation in Beef Cows
… or low endophyte fescue pastures during late gestation to determine if exposure to ergot alkaloids in utero results in IUGR and if calves from these pregnancies have altered growth performance. Creep feeding was evaluated as a mitigation strategy for impaired calf growth due to fescue …

Phenotypic Consequences of Gestation Temperature in the Northern Watersnake, Nerodia Sipedon
… consequences. I explored the influence of gestation temperature on offspring phenotypes produced by gravid Northern Watersnakes (Nerodia sipedon) maintained at constant temperatures of 23, 26, and 29°;C. Swimming speed, defensive strikes, and flight response were tested at 1 and 26 weeks of …

Glucose and insulin dynamics in late gestation mares and neonatal foals
… Mismanagement of maternal nutrition during gestation could predispose the offspring to metabolic disorders (e.g. insulin resistance) later in life. In horses, insulin resistance is associated with increased risk for development of laminitis. These studies measured insulin sensitivity and …

Maintenance of fetal membrane integrity by cyclic cellular transitions during gestation and parturition
… preterm birth, and neonatal death. During gestation, membranes repair and remodel through a balanced collagenolytic process of the matrix. Individual sites of membrane remodeling have been identified and termed ‘microfractures.’ However, the roles of membrane cells, amnion epithelial (AEC) …

Effects of Phase Feeding During Gestation on Gilt Performance, Offspring Quality and Robustness
… of a standard diet from breeding to d 112 of gestation (1.7 g Lys/kcal ME; 3276 kcal ME/kg); Bump feeding (Bump-f), the standard diet at 2.21 kg/d from breeding to d 89 and 2.61 kg/d from d 90 - 112; Phase feeding (Phase-f ), 2.21 kg/d from breeding to d 89 (1.5 g Lys/kcal ME; 3275 kcal ME/kg) …

Effects of restricted feeding schedule during development and gestation on gilt and sow performance
The overall objective of these experiments was to develop management and feeding programs to increase sow longevity and productivity by improving welfare conditions. In Exp. 1, 208 gestating sows and 288 gestating gilts were utilized to determine the effect of feeding frequency (2 vs. 6) on …

Differential gestation feeding levels on sow and litter performance, nutrient digestibility and energy homeostasis
… effects of differential feeding levels during gestation on sow and litter performance, nutrient digestibility and energy homeostasis. In Exp. 1, a total of 160 multiparous sows were allotted to 1 of 4 dietary treatments using a randomized complete block design with BW (BW) and backfat (BF) as …

Influence of energy level during gestation on the postpartum endocrine system in the mare
… (NRC, 1978), respectively, for the last 90 d of gestation. During the first 30 d of lactation, all mares were fed the NRC (1978) recommendations for lactation. The 120% DE-fed mares had an advantage of .18 kg (P<. 03) ADG during the last 90 d of gestation. The length of gestation and foal birth …

The effect of a zinc deficiency and alcohol intake during gestation in the rat
The effect of alcohol and/or zinc deficiency was evaluated in seven groups of pregnant rats and their pups. Females which had been acclimated to alcohol before breeding were fed liquid alcohol diets with either 14 or 0.1 ppm Zn. Comparisons were made with animals pair fed isocaloric liquid …
