Evaluation of glucose supplement provided with enrichment to reduce hunger induced stress in gestating sows
… and physiology of feed restricted pregnant sows. First parity pregnant sows (N =36) with an average weight of 200 kg were randomly assigned into three treatment groups: negative control group sows were not provided with AHBs with enrichment (NEG), positive control sows were provided with …

Effect of fenbendazole on shedding and embryonation of Ascaris suum eggs in naturally infected gestating sows
… with A suum were conducted. Breeding gilts and sows were identified with natural A suum infections and allocated to one of 4 treatments: CNT = untreated controls, TX1 = 545.5 mg fenbendazole for one day, TX2 = 545.5 mg fenbendazole daily, for 3 consecutive days (1636.5 mg total), and TX3 = …

Comparative digestibility of energy and nutrients in diets fed to sows and growing pigs
… digestibility (ATTD) of nutrients is greater in gestating sows fed close to the maintenance requirement than in growing pigs allowed ad libitum access to diets. Therefore, there is a need in North America to generate separate digestibility values for gestating sows and growing pigs as only 1 …

Digestibility of calcium and phosphorus and effects of microbial phytase in diets fed to growing pigs or gestating sows
… Ca, P, and phytase in diets fed to gestation sows or growing pigs. In Exp. 1, two experiments were conducted to test the hypothesis that standardized total tract digestibility (STTD) of Ca and the response to microbial phytase is constant among different sources of calcium carbonate and that …

Impact of feed additives in swine diets and the effect of corn particle size on metabolizable energy in gestating sows
… size on digestible and metabolizable energy in gestating sows. In experiment 1, 5 treatments consisting of a control, or the control with 2 levels of formic acid (0.36 % and 0.6%), or the control with a blended product containing 60% formic acid and 40% lignosulfonate (blended product was …

Effect of alternative, individual and group housing systems, and management factors in group pens on the well-being of gestating sows
… of referendum that ban gestation stalls for sows, crates for veal calves, and battery cages for laying hens. Currently no scientific information support the current notion that these housing systems compromise animal well-being nor support that any of the current alternative housing systems …

Comparative Amino Acid Digestibilities in Growing Pigs and Sows
… conducted to investigate the extent to which gestating and lactating sows are able to digest amino acids. A procedure for surgically inserting a T-cannula in the distal ileum of gestating sows was developed, and ileal fluid was successfully collected from sows in gestation as well as in …

Investigating the influence of dietary fiber source and multicarbohydrase supplementation on digestibility, energy, systemic health, water balance, and gut motility in gestating sows
… mechanisms associated with multicarbohydrases in gestating sows fed soluble and insoluble fiber diets typical to U.S. production. A total of 36 confirmed gestating sows (186 ± 4.6 kg BW) were blocked by parity randomly assigned to 1 of 4 diets (n=9) in a 2×2 factorial arrangement of treatments on …

Effects of restricted feeding schedule during development and gestation on gilt and sow performance
… 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 performance and welfare issues. Feeding frequency had no affect on growth and reproductive performance in gestating sows; however, …

Assessing the well-being of gestating submissive sows in group pens using multiple welfare metrics
… agriculture today, specifically how to keep gestating sows. Internationally, many countries such as the European Union, Canada, and Australia, as well as some states within the U.S. have banned gestation crates. Consumer and legislative pressure have been the greatest push for these changes, …

Nutritional evaluation of rice coproducts fed to pigs
… GE and nutrients in FFRB and DFRB determined in gestating sows is greater if feed is provided at 1.5 × the ME required for maintenance than at 3.5 × the ME requirement. The second objective of this experiment was to test the hypothesis that the ATTD of GE and nutrients and the concentrations of …

A pilot study on the effects of sow management practices on piglet immune responsiveness to weaning stress
… of maternal prenatal stress exposure of the gestating sow on the developing immune system of her offspring is not well understood. There is limited data that primarily focuses on the health and well-being of the neonates of livestock animals, principally within the swine industry, in relation …

Corn Co-Products as Feed Ingredients for Swine: Effects on Growth, Carcass Composition and Fiber and Amino Acid Digestibility
… gluten feed (CGF) and corn germ meal (CGM), for gestating sows and starter (S), grower (G) and finisher (F) pigs was determined. Effects on growth and carcass composition of pigs fed diets containing various amounts of CGF and CGM were evaluated. The amino acid and fiber digestibilities of corn …

The nutritional value of flaxseed meal for swine
… pigs (32 pigs, initial weight 70 ± 3 kg) and gestating sows (26 pigs, parities 2 – 4). Animals were fed wheat/barley based diets containing 0, 10, 20 or 30% FSM. Faecal grab samples were collected for 3 days after a dietary adaptation period. The apparent digestibility of nutrients in FSM was …

A pilot study on the productivity and behavior of the gestating sow housed in a flex stall
… community and the general public. The housing of gestating sows, particularly individual housing, is one of the most critical concerns in farm animal welfare. We hypothesize that the physical size of the standard gestation stall may limit movement and evoke demands and challenges on the sow to …

Hybrid rye may partially or fully replace corn in diets fed to growing or reproducing swine
… that hybrid rye may replace corn in diets for gestating and lactating sows, weanling and nursery pigs, and growing-finishing pigs without negatively impacting growth performance. In experiment 1, 45 sows per treatment were fed diets in which 0, 25, 50, or 75% of corn was replaced with hybrid …
