Segregated Early Weaning (SEW) of Pasture-farrowed Pigs
and Implications Segregated early weaning (SEW) works well with pasture-farrowed pigs. The SEW pasture-farrowed pigs weighed about the same as conventionally weaned pigs at 9 weeks of age with lower death losses (about 2% less). For the period 5Ð9 weeks of age the SEW pigs gained more rapidly and were more efficient converting feed to live gain than pigs weaned at 5 weeks of age and moved to an...

Introduction: Intense exercise leads to a decrease in immune system. The aim of this study was to investigate the effect of short-term garlic extract supplementation on some cellular immune system factors after intense exercise in karate athletes. Methods: Eighteen young men (with a mean age of 20.07±4.46, BMI 22.72±2.99 kg/m2) volunteered to participate in this semi-experimented...
متن کاملCandida albicans Structural and Secreted Proteins Modulate CD4/CD8 Ratio in Tumor Infiltrating Lymphocytes of Spontaneous Adenocarcinoma Bearing Mice
Background: Candida albicans is one of the most important opportunistic pathogens that suppress immunologic mechanisms of the host. It is speculated that structural and secretory proteins of C. albicans have immunomodulatory effects in cancer. Objective: To evaluate the effects of C. albicans structural and secreted proteins on intratumoral CD4/CD8 ratio as well as the survival rate in BALB/c t...
متن کاملImproved weight gain in pigs using levamisole as an immunomodulator
Metho ds : Piglets (N = 1606) from a commercial segregated early-weaned (SEW) herd were randomly assigned either to receive one injection of levamisole within 24 hours of birth (T1 group), to receive levamisole once within 24 hours of birth and again at weaning (T2 group), or to a control group. Pigs were individually weighed within 24 hours of birth, at weaning, and at 7 weeks of age. Differen...

An inactivated vaccine prepared from broth culture supernatant of Mycoplasma hyopneumoniae with an aluminum adjuvant was evaluated in three herds (herd A: specific pathogen-free herd, herd B: high health status herd with no clinical signs of respiratory infection, herd C: low health status herd with serious epidemiological and economical problems). A total of 212 pigs from the three herds were ...
