Organic selenium and vitamin E for gilts and sows bred in equatorial climate.

The aim of this study was to evaluate the dietary supplementation of organic selenium (Se) and vitamin E for sows from 1st and 2nd parity order, without adiabatic cooling on physiological parameters, reproductive performance, milk composition, litter performance and blood concentrations of antioxidant enzymes. A total of 96 sows were allotted in a 4 × 2 completely factorial design, with 4 experimental groups and 2 parity orders (1st and 2nd). The experimental groups consisted of: ACCon-sows receiving adiabatic cooling and no dietary supplementation of organic Se and vitamin E; WACCon-sows without adiabatic cooling and no dietary supplementation of organic Se and vitamin E; WACSe-sows without adiabatic cooling with dietary supplementation of 0.

Effects of Saccharomyces cerevisiae var. boulardii CNCM I-1079 on performance, colostrum and milk composition, and litter performance of mixed-parity sows in a tropical humid climate.

This study aimed to evaluate the effects of Saccharomyces cerevisiae var. boulardii (SB) for sows on their productive performance, colostrum and milk composition, and litter performance, in tropical humid climatic conditions. A total of 105 sows (Topigs Norsvin®) were allotted to a 5 × 3 completely randomized factorial design, with five diets (control diet; SBGL4 and SBGL8: 0.

Nutritional adjuvants with antioxidant properties in the treatment of canine leishmaniasis.

Clinical improvement of dogs treated for canine leishmaniasis (CanL) requires reducing Leishmania infantum loads, which depend on intracellular oxidant compounds to destroy the parasite. However, oxidative species' excess and antioxidants consumption can culminate in oxidative stress, resulting in increased, widespread inflammation. We aimed to evaluate if early or late addition of nutritional adjuvants (NAs) - omega-3 polyunsaturated fatty acids and B vitamins - to anti-Leishmania drugs (ALDs) in the treatment of CanL would be clinically beneficial.

Dietary iron chelate for sows and effects on iron supplementation in piglets.

In order to evaluate iron chelate in diets for sows during gestation and lactation and its effects on iron supplementation for piglets, a total of 50 pregnant sows in the third parity order were distributed according to a randomized block design with two treatments: diet without iron chelate supplementation (n=20); diet supplemented with 0.15% of iron chelate (n=30). The litters of sows were distributed into five different treatments: sows without iron chelate supplementation and piglets receiving intramuscular iron-dextran; sows without iron chelate supplementation and piglets receiving oral iron supplementation; sows supplemented with iron chelate and piglets receiving intramuscular iron-dextran; sows supplemented with iron chelate and piglets receiving oral iron supplementation; sows supplemented with iron chelate and piglets without iron supplementation.

Seminal plasma proteins of adult boars and correlations with sperm parameters.

The present study was conducted to identify the major seminal plasma protein profile of boars and its associations with semen criteria. Semen samples were collected from 12 adult boars and subjected to evaluation of sperm parameters (motility, morphology, vitality, and percent of cells with intact acrosome). Seminal plasma was obtained by centrifugation, analyzed by two-dimensional SDS-PAGE, and proteins identified by mass spectrometry (electrospray ionization quadrupole time-of-flight).
