Abstracts - Management

The behavior of three antibiotics (bacitracin, chlortetracycline, and tylosin) and two classes of antibiotic resistance genes (ARGs), tet and erm, were monitored in swine manure slurry under anaerobic conditions.

The aim of the experiment was to study the effect on litter performance of two oral supplementation strategies on piglets born weighing 1.35 kg or less.

Biosecurity is a useful measure to promote the reduction of antimicrobial use in the pig industry.

These results demonstrate that management options can affect the reproductive performance and injuries of gestating sows in the ESF system.

It can be concluded that litter performance at weaning is related to birth weight coefficient of variation.

In conclusion, some management practices, such as feeding strategy of breeding gilts, housing conditions of sows...have an influence on the outcome of reproductive parameters.

New neonatal strategies of micronutrient supplementation to piglets may be required nowadays.
