"Data analysis of twenty East Westphalian piglet production farms with regard to in0testinal health and the use of zinc oxide in the weaning Phase"
This study “Data analysis of twenty East Westphalian piglet production farms with regard to intestinal health and the use of zinc oxide in the weaning phase” examines the effects of various farm factors on the gut health of piglets and the use of zinc oxide in so-called pharmacological dosing after weaning. Until June 2022, zinc oxide was used as a preventive measure and to treat diarrhea in piglets in doses that exceeded requirements, but this practice has since been banned due to environmental concerns and the promotion of antibiotic resistance. The aim of the survey was to identify farm strategies and a possible link with gut health and the incidence of diarrhea in piglets.
Twenty piglet production farms in East Westphalia were analyzed regarding to operational key figures, housing conditions, feeding strategies and health management. In particular, the effects of housing and feeding and the use of zinc oxide on the intestinal health of piglets before and after weaning were investigated. The data collection included clinical data, Climate measurements and the recording of feeding and performance criteria.
The results show that animal health varied depending on housing conditions, Management and feeding. Farms differed significantly in the health status of the piglets, particularly with regard to the occurrence of diarrheal diseases. The use of zinc oxide was associated with lower diarrhea rates. Farms using pharmacological doses of zinc oxide had lower mortality rates during the piglet rearing and fattening period. Alternatives to the use of high concentrations of zinc oxide in the feed were used on many farms, in particular the Adjustment of protein and amino acid levels in the feed of weaned piglets. It was found that a reduction of the crude protein content in piglet feed and a balancing with essential amino acids was implemented on many farms, with the aim of positively influencing intestinal function. Dietary fiber and zootechnical feed additives, in particular probiotic microorganisms, were regularly used. Biosecurity management showed clear differences between the farms. The importance of the intestinal microbiota was investigated in an associated study (Lührmann et al. 2021).
The available database shows a variety of efforts to establish an optimal feeding strategy to improve the health and performance of piglets. There is a need for further research to develop sustainable alternatives to the use of zinc oxide and to improve management in piglet production. The work shows that a holistic view of housing conditions, feeding strategies and health management is necessary, to improve piglet health and effectively prevent diarrhea. The elimination of zinc oxide requires the development and implementation of alternative strategies that are equally effective and environmentally friendly.
