Effect of dietary supplementation of oregano essential oils to sows on colostrums and milk composition, growth pattern and immune status of suckling pigs

Supplementing sow diets with 250 mg/kg of oregano essential oils during gestation and lactation did not affect the growth potential of and immune responses in suckling piglets.

Abstract

Probiotics and antibiotics as additives for sows and piglets during nursery phase

Sows and piglets diets supplemented with probiotics are effective in maintaining animal performance and control of diarrhea during the nursery phase.

Abstract

Enteral arginine does not increase superior mesenteric arterial blood flow but induces mucosal growth in neonatal pigs

Partial enteral feeding increases superior mesenteric artery blood flow in the neonatal pig compared with total parenteral nutrition.

Abstract

Increasing omega-3 levels through dietary co-extruded flaxseed supplementation negatively affects pork palatability

Feeding co-extruded flaxseed to increase omega-3 fatty acid content in trimmed loin muscle did not result in levels sufficient to meet label requirements and had limited effects on palatability.

Abstract

Effect of dietary CLA administration on fatty acid composition and lipogenic and lipolytic enzyme activities in suckling and weaned piglets

The concentration of fatty acids in subcutaneous fat and liver tissues of piglets 35 d after weaning is largely dependent on the CLA content of piglet diet rather than CLA enrichment of sow diet.

Abstract

The metabolic availability of threonine in common feedstuffs fed to adult sows is higher than published ileal digestibility estimates

Using ileal digestibility values determined in growing pigs to formulate sow diets may lead to overfeeding of sows with protein and can negatively affect overall production efficiency through increased cost and excess nitrogen excretion.

Abstract

Effect of restricted feeding and realimentation periods on pork quality and fatty acid profile of M. longissimus thoracis

Modifying feed intake during growth may change pork nutritional value and tenderness.

Abstract

Analysis of water, feed intake and performance of lactating sows

An enhanced feed and water intake during lactation may increase weaning weight of piglets and decreases relative body weight loss of sows.

Abstract

Effects of liquid metabolite combinations produced by Lactobacillus plantarum on growth performance, faeces characteristics, intestinal morphology and diarrhea incidence in postweaning piglets

Metabolite combinations produced by L. plantarum strains are potential alternatives to antibiotics that could be used as growth promoter in postweaning piglets.

Abstract

Effects of different probiotic complexes of lactic acid bacteria on growth performance and gut environment of weaned piglets

Different probiotic complexes of lactic acid bacteria improved growth performance and feed conversion in the first two weeks post-weaning, but the gut environment was improved in all period.

Abstract

Relationship between proteome changes of Longissimus muscle and intramuscular fat content in finishing pigs fed conjugated linoleic acid

Dietary conjugated linoleic acid increases intramuscular fat content in finishing pigs.

Abstract

Limited and excess dietary protein during gestation affects growth and compositional traits in gilts and impairs offspring fetal growth

Gestation diets containing protein at 50 and 250% of recommendations led to marked changes in protein and fat metabolism in gilts resulting in fetal growth retardation of 15%.

Abstract

Effects of restricting energy during the gilt developmental period on growth and reproduction of lines differing in lean growth rate: Responses in feed intake, growth, and age at puberty

Restricting energy during the gilt development slightly delays the mean age at puberty.

Abstract

Evaluation of glycerol, a biodiesel coproduct, in grow-finish pig diets to support growth and pork quality

8% crude glycerol can be added to the diet and used as an effective alternative energy source to partially replace corn.

Abstract

The effect of cereal-derived beta-glucans and exogenous enzyme supplementation on intestinal microflora, nutrient digestibility, mineral metabolism and volatile fatty acid concentrations in finisher pigs

Barley-based diets have more beneficial effects on gut health, oat-based diets have higher potential to enhance beneficial microbial populations and endogenous β-glucans show better prebiotic properties.

Abstract

The threonine requirement of sows increases in late gestation

Feeding a single amount of amino acids (AA) throughout gestation results in overfeeding AA in early gestation and underfeeding AA in late gestation.

Abstract

Vomitoxin concentration in nursery pig diets and the effectiveness of commercial products to mitigate its effects

The use of mycotoxins absorbents in sever vomitoxin contaminated diets may reduce the negative impact of vomitoxin on piglet performance.

Effect of dietary protein level on growth performance, indicators of enteric health, and gastrointestinal microbial ecology of weaned pigs induced with postweaning colibacillosis

Feeding low CP, AA supplemented diets can help to improve poor growth performance and enteric disorders of the weaned pigs.

Dose-response effect of fish oil substitution in parturition feed on erythrocyte membrane characteristics and sow performance

Osmotic resistance of erythrocytes was not altered by increasing amounts of n-3 PUFA, whereas oxidative stability of erythrocytes, as well as oxidative parameters in plasma, were affected.
