"A Centre of Excellence for Pig Development"

Research

The PIB undertakes research in the fields of nutrition, breeding and production. The research is mainly applied and is aimed at finding solutions to the problems that Zimbabwean pig producers will be facing. Due to resource constraints most of the research is done in collaboration with other research institutions and companies in Zimbabwe. Two research projects were done in collaboration with the University of Zimbabwe from 2013 to 2014. One of the studies involved assessing the meat consumption patterns in urban and rural Zimbabwe. The other study was on mitigating the occurrence and the effects of undersized piglets in a litter.

In 2019, two papers were published at the Research Council of Zimbabwe. The first paper evaluated the dietary inclusion of moringa leaf meal on the performance of piglets. Adding the meal extract improved the growth rate of piglets. The second one focused on using cowpea meal as a soya bean meal substitution. Results and papers are available on the following link;

In 2021 one paper was published in the journal of Tropical Animal health and production titled Efficacy of neem (Azadirachta indica) aqueous fruit extracts against Sarcoptes scabiei var. suis in grower pigs.

Abstract

The acaricidal activity of Azadirachta indica (neem) aqueous fruit extracts was evaluated against Sarcoptes scabiei var. suis (mange mites) in an on-farm trial using grower pigs. Aqueous neem fruit extracts of three concentrations 5%, 10%, and 25% w/v and a commercial acaricide, 12.5% amitraz-based Triatix spray (positive control), were compared with pigs that received no treatment (negative control). Thirty grower pigs of the Dalland breed were allocated to the five treatments in a completely randomized experiment. Each experimental animal was sprayed on day 0 and again on day 7. Counts of mange mites, scoring of lesion index, and calculation of rubbing index were done weekly. Topical application of 25% aqueous neem fruit extract had a higher efficacy ratio (p < 0.05) than the other fruit extract concentrations, and performed similarly to an amitraz-based acaricide, suggesting a dose-dependent response. Amitraz (positive control) cured clinical mange on grower pigs after 5 weeks and 25% aqueous neem fruit extract 6 weeks post-treatment. The results indicated that aqueous neem fruit extracts have acaricidal effects against mange mites and can provide a cheaper, safer, and more eco-friendly alternative for the control of Sarcoptes mange in pigs.
