Digestibility of dietary fiber by growing pigs
… (DDGS) and other high fiber ingredients to growing pigs. The objective of Exp. 1 was to measure the effects on digestibility of AA, energy, and fiber of adding 30% DDGS to a corn soybean meal diet and to measure intestinal transit time. Growing pigs were cannulated at the terminal ileum and …

Requirements for digestible calcium by growing pigs
… to determine the digestible Ca requirements by pigs from 11 to 25 kg and from 50 to 85 kg as indicated by growth performance and bone ash. In Exp. 1, the hypothesis was that the requirement to maximize growth performance of 50- to 85-kg pigs expressed as the STTD Ca:STTD P ratio, is less than …

Comparative Amino Acid Digestibilities in Growing Pigs and Sows
… were higher for lactating sows than for growing pigs. Gestating sows had AIDs that were intermediate between growing pigs and lactating sows. By correcting AIDs for the non-specific endogenous losses of amino acids estimated after feeding a nitrogen-free diet, standardized ileal amino …

The nutritional value of hybrid rye fed to growing pigs
… of hybrid rye and other cereal grains fed to growing pigs. In Exp. 1, the objective was to determine the standardized ileal digestibility (SID) of AA in 3 varieties of hybrid rye and in one source of barley, wheat, and corn. Seven ileal cannulated barrows (initial BW = 26.1 ± 2.4 kg) were …

Composition and digestibility of different sources of feed phosphates by growing pigs
… including those potentially harmful for growing pigs. Seven sources of monocalcium phosphate (MCP), 4 of dicalcium phosphate (DCP), 2 of monosodium phosphate (MSP), and 1 magnesium phosphate (MgP) were used. Each feed phosphate was analyzed for minerals and then the P and Ca bound to …

Examining the Influence of Muscle Fiber Type on Protein Turnover Signaling in Growing Pigs
… turnover in skeletal muscle hypertrophy in growing pigs. Downregulated protein synthesis signaling and reduced expression of type II MyHC isoforms have been reported in skeletal muscles of low birth weight (LBWT) neonatal pigs. Therefore, we sought to determine whether these changes are …

Comparative digestibility of energy and nutrients in diets fed to sows and growing pigs
… 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 energy value is used to feed all categories of pigs. The objective …

Isoquinoline alkaloids in diets for young growing pigs improve nutrient digestibility and gut health
… in corn-soybean meal (SBM) diets fed to young growing pigs on growth performance, gut health, energy and nutrient digestibility, and digestible energy (DE) and metabolizable energy (ME) concentrations in the diets. In the first experiment, 32 ileal cannulated barrows (12.19 ± 1.38 kg) were …

The relationship between protein and phosphorus digestion and retention in growing pigs and broiler chickens
… and Phosphorus Digestion and Retention in Growing Pigs and Broiler Chickens. Major Professor: Dr. Layi Adeola. The objective of this study was to investigate the relationship between protein and P digestion and retention in growing pigs and broiler chickens. The methodology of determining …

Digestibility of energy and nutrients in distillers dried grains with solubles fed to growing pigs
… standardized ileal digestibility (SID) of AA by growing pigs in European DDGS produced from wheat, maize, or wheat-maize mixtures. Twelve barrows (average initial BW: 23.0 ± 2.2 kg) were surgically equipped with a T-cannula in the distal ileum and randomly allotted to a replicated 6 × 6 Latin …

Impact of virginiamycin on the development of intestinal structure and functional capacity in growing pigs
… corn-soybean diet). Within each pen, pigs were further randomized to a time point (7 or 14 days). Intestinal samples were obtained for assessment of gross morphology, histomorphology, immunohistochemistry, biochemical measurements, disaccharidase activity, and nutrient and ion …

The effect of high-fiber diets on nutrient utilization and intestinal morphology of growing pigs
… on mineral balance and intestinal.morphology of growing pigs. Fiber sources were added to corn-soybean meal diets at levels which increased neutral-detergent fiber levels by 6 to 8%. In experiment 1, 10% oat hulls (OH) decreased Ca (P<.06) and Zn (P<.01) balances of pigs after a 7 d feeding …

The effects of periodic environmental enrichment at different life stages on the welfare and production of growing pigs
… is known that the welfare of intensively raised pigs is improved when housed in enriched versus barren conditions, however, the interaction between enrichment and different life stages is largely understudied. The current study evaluated the influence of periodic enrichment during different life …

INTERACTIVE EFFECT OF DIETARY FIBRE AND IMMUNE CHALLENGE ON THREONINE REQUIREMENT AND INTESTINAL BARRIER FUNCTION IN GROWING PIGS
… for protein deposition (PD) and growth in pigs. Fibre and threonine (Thr) may also play an important role in intestinal barrier function. Therefore, this thesis evaluated the independent and combined effects of high DF and immune challenge [Salmonella typhimurium and systemic E. coli …

Digestibility of calcium and phosphorus and effects of microbial phytase in diets fed to growing pigs or gestating sows
… 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 the STTD …

Copper from copper hydroxychloride in diets for growing pigs increases feed efficiency, improves energy utilization and changes intestinal microbial activity
… intestinal permeability, and lipid metabolism of pigs. The first 3 experiments were conducted to determine effects of Cu hydroxychloride on digestible energy (DE) and metabolizable energy (ME), apparent total tract digestibility (ATTD) of energy and acid hydrolyzed ether extract (AEE), diarrhea …

Influence of physicochemical characteristics and inclusion rate of fiber-rich ingredients on utilization of dietary fiber and energy by growing pigs
… fiber, energy, and nutrients in diets fed to pigs. Experiment 1 was conducted to quantify nutrient and fiber fractions of feed ingredients and to determine in vitro apparent ileal digestibility (IVAID) and in vitro apparent total tract digestibility (IVATTD) of DM and OM in each ingredient. …
