To assess the effects of creep feed consumption on individual intake characteristics and performance group-housed weaned pigs, 16 litters (149 piglets) were fed a commercial (3,040 kcal NE/kg, 15.2 g lysine/kg) supplemented with 1% chromic oxide. Another five (48 not given access to (no-feed). Piglets at 28 d after birth. On 18, 22, 27 age, fecal samples from all piglets taken using loops. A green color feces indicated that piglet had eaten feed. green-colored three times considered as...

Dietary carbohydrate fibers are known to prevent immunological diseases common in Western countries such as allergy and asthma but the underlying mechanisms largely unknown. Until now beneficial effects of dietary mainly attributed fermentation products anti-inflammatory short-chain fatty acids (SCFAs). Here, we found present a new mechanism by which can be anti-inflammatory: commonly consumed fiber, pectin, blocks innate immune receptors. We show that pectin binds inhibits, toll-like...

Starch is the main source of energy in commonly used pig diets. Besides effects related to extent starch digestion, also several variation digestion rate have recently been demonstrated non-ruminants. Different rates animals and vitro models reported, depending on botanic origin starch. Starches from different sources differ widely structural molecular properties. Predicting effect properties kinetics based existing literature hampered by incomplete characterization starches, or a selective...

Scope We aimed to investigate the effects of three different soluble pectins on digestion other consumed carbohydrates, and consequent alterations microbiota composition SCFA levels in intestine pigs. Methods results Piglets were fed a low‐methyl esterified pectin enriched diet (LMP), high‐methyl (HMP), hydrothermal treated soybean meal (aSBM) or control (CONT). LMP significantly decreased ileal digestibility starch resulting more fermentation proximal colon. In ileum, present was...

Feed intake characteristics of 192, 27-d-old weanling pigs housed in groups and given ad libitum access to feed water were measured individually with the use computerized feeding stations. The either homogeneous or heterogeneous as BW distribution; three defined initial classes used (mean 6.7, 7.9, 9.3 kg). effects distribution, class, sex studied regard average performance traits, latency time (interval between weaning first intake), (intake during 24 h following daily increase interval day...

Toasting during the production of rapeseed meal (RSM) decreases ileal crude protein (CP) and amino acid (AA) digestibility. The mechanisms that determine decrease in digestibility have not been fully elucidated. A high quality, low-denatured, RSM was produced toasted up to 120 min, with samples taken every 20 min. aim this study characterize secondary structure chemical changes proteins glucosinolates occurring toasting effects on its vitro CP solubility increase intermolecular β-sheets...

To assess the effects of 2 high intensity sodium saccharine-based sweeteners on individual feed intake characteristics and performance group-housed weaned pigs, one hundred ninety-eight 26-d-old weanling pigs were given ad libitum access to 3 dietary treatments containing: no additional sweetener (control), 150 mg (Sucram C-150)/kg, or 3D)/kg. At weaning, piglets allocated 18 pens (11 pigs/pen) based BW, sex, ancestry, randomly assigned with 6 per treatment. The equipped computerized feeding...

Consumption of non-starch polysaccharides (NSP) is associated with reduced risk obesity. This study aimed to compare the effects cereals (oats) and legumes (soybean), rich in different classes NSP, on appetite regulation fat accumulation rats. Soy pectin fermented more efficient than cereal arabinoxylan oat β-glucan were utilized mainly caecum Only small amount maltodextrin, cello-oligosaccharides xylo-oligosaccharides detected digesta. Caecal fermentation soy produced significantly higher...

Reducing crude protein (CP) in broiler feed is a nutritional strategy that allows to partially reduce dietary soybean meal (SBM) inclusions costs, with proven benefits. In addition, reduction of CP leads lower electrolyte balance (dEB) due the concomitant potassium (K). The aim present study therefore two-fold: 1) evaluate potential until performance drops (1, 2 or 3 % points reduction) and 2) combine it dEB (by reducing K) validate benefit reduced dEB/K on litter quality without...

Abstract Individual food intake characteristics and indicators of gut physiology group-housed weanling pigs were measured in relation to pre-weaning consumption creep food. Additionally, the effects on body weight gain assessed. A total 48 litters was used two trials. From 11 days age until weaning (day 28), all given a (12·7 MJ net energy (NE) per kg, 15·2 g lysine kg) supplemented with 10 chromium III oxide kg. Piglets showing green-coloured faeces three sampling designated as good eaters,...

Effects of physicochemical characteristics feed ingredients on DE and ME apparent total tract digestibility (ATTD) GE, DM, nutrients were determined in growing pigs using with different ratios between insoluble dietary fiber (IDF) soluble (SDF). Eighty barrows (BW: 48.41 ± 1.50 kg) allotted to a randomized complete block design 10 diets eight replicate per diet. Dietary treatments included corn-based diet, wheat-based corn–soybean meal (SBM) seven based mixture the corn–SBM diet canola meal,...

This study aimed to examine in vivo starch digestion kinetics and unravel the mechanisms of hydrolysing enzymes. Ninety pigs (23 (sd 2·1) kg body weight) were assigned one nine treatments a 3×3 factorial arrangement, with source (barley, maize, high-amylose (HA) maize) form (isolated, within cereal matrix, extruded) as factors. We determined coefficients (DC), breakdown products digesta retention times four small-intestinal segments (SI1-4). Starch SI2 fed barley exceeded HA maize by...

Effects of inclusion rate fiber-rich ingredients on apparent ileal digestibility (AID) and total tract (ATTD) GE the concentration DE ME in mixed diets fed to growing pigs were determined. The hypothesis was that increasing fiber decreases GE, thus, contribution from hindgut fermentation because greater concentrations may reduce ability microbes ferment fiber. Twenty ileal-cannulated (BW: 30.64 ± 2.09 kg) allotted a replicated 10 × 4 incomplete Latin Square design with four 26-d periods....

Abstract Physicochemical properties of diets are believed to play a major role in the regulation digesta transit gastrointestinal tract. Starch, being dominant nutrient pig diets, strongly influences these properties. We studied transport solids and liquids through upper tract ninety pigs 3 × factorial arrangement. Dietary treatments varied starch source (barley, maize high-amylose maize) form (isolated starch, ground cereal extruded cereal). Mean retention times (MRT) ranged 129–225 min for...

An experiment was conducted to quantify nutrient and fiber fractions of feed ingredients determine in vitro apparent ileal digestibility (IVAID) total tract (IVATTD) DM OM each ingredient. Ten that vary concentration composition were used: corn, wheat, soybean meal (SBM), canola meal, distillers dried grains with solubles (DDGS), corn germ copra expellers, sugar beet pulp (SBP), synthetic cellulose (SF), pectin. Correlations between chemical physical characteristics IVAID IVATTD determined....

Thermal damage to proteins can reduce their nutritional value. The effects of toasting time on the kinetics hydrolysis, resulting molecular weight distribution 00-rapeseed meal (RSM) and soluble insoluble protein fractions separated from RSM were studied. Hydrolysis was performed with pancreatic proteases represent in vitro digestibility. Increasing linearly decreased rate hydrolysis fractions. extent was, average, 44% higher for compared fraction. In contrast, fraction 3-9-fold than that by...

Forty 4-wk-old crossbred weanling barrows weighing 8.0 kg (SE = 0.13) were assigned to one eight groups (five per group) based BW litter. Groups allotted two lighting schedules: 8 h light:16 darkness or 23 light:1 darkness. Each group housed in climate respiration chamber. Piglets had ad libitum access feed water. Energy nitrogen balances, heat production, ADFI, ADG measured...

Three batches of weanling pigs (total n =310 pigs) were used in a 34‐day experiment to validate the use an IVOG ® feeding station as tool for monitoring individual feed intake group‐housed pigs.
