Six treatments arranged factorially (2 3) with two types gilt (entire (EG) vs. immunocastrated (IG)) three experimental diets (control high energy low crude protein...

The introduction of antimicrobial residues in the food chain has a significant impact on human health. An innovative solution to avoid their presence meat is adaptation current control methods for use with vivo matrixes. Thus, aim was obtain paired blood and muscle samples from pigs treated some main antimicrobials currently used veterinary medicine (oxytetracycline, sulfamethoxypyridazine, enrofloxacin, amoxicillin), compare rate depletion both Antimicrobial concentrations were determined...

Many of the infectious diseases that affect livestock have bacteria as etiological agents. Thus, therapy is based on antimicrobials leave animal’s tissues mainly via urine, reaching environment through slurry and waste water. Once there, antimicrobial residues may lead to antibacterial resistance well toxicity for plants, animals, or humans. Hence, objective was describe rate excretion in urine order select most appropriate molecule while reducing harmful effects. 62 pigs were treated with...

Nowadays, there is a great concern about the prevalence of multidrug resistant Enterococcus spp. and Enterobacteriaceae in food-producing animals.

Gilts produce less colostrum with lower immunoglobulin G concentration than multiparous sows do. An extra dose of (30 mL) from was administered to piglets gilts ascertain its effects on performance and health in farm conditions, especially the smallest (birth weight < 1.100 kg; Q1). The control group (CON) consisted 200 18 (50 piglets) 201 16 (52 formed supplemented (SUP). Colostrum supplementation increased homogeneity (days 21 60) average daily gain (ADG; days 0–10, 0–21, 0–60) a...

The aim was to assess the reproductive efficiency of different techniques used preserve spermatozoa in artificial insemination semen doses (AI-doses) by evaluating refrigeration at 15°C, cryopreservation and encapsulation. Forty-two hyperprolific sows were treated with buserelin inseminated once a single fixed time. fertility rate, embryonic vesicles viability early mortality (arrested conceptuses) evaluated post-mortem 24th day pregnancy, analysed order effectiveness each proposed...

Abstract Background Early onset of a gilt´s puberty is needed for adequate economic performance in farms, because it indicates her reproductive and longevity. Therefore, an effective diagnosis needed. Our purpose was to compare different procedures (external characteristics, blood progesterone analysis ultrasonography diagnosis) detect 70 gilts (Topigs TN70; 240 days old) on farm conditions. Postmortem examination the standard reference. Multiple logistic regression used identify which...
