Practices and impact of biosecurity on pig performance in the West Region of Cameroon

TL;DR

This study examines how biosecurity practices on pig farms in Cameroon's West Region affect pig health and production, finding that poor biosecurity is linked to higher mortality rates.

Contribution

The study provides new insights into biosecurity practices and their impact on pig production performance in Cameroon's West Region.

Findings

Most farms used antiparasitics and antibiotics, but only a quarter vaccinated against swine erysipelas.

Over half of the farms had low biosecurity scores, with personnel and visitor measures being the weakest.

Farms with poor biosecurity had significantly higher mortality rates than those with better practices.

Abstract

In Africa, pig significantly contributes to animal protein supply to enhance food security. Pig farming in Cameroon is subject to perpetual health threats, with the spread of several diseases which strongly impact the production. This study aimed to evaluate the biosecurity compliance in pig farms in the West Region of Cameroon and assess its relationship with production performance. During on farm visit and face to face interview, data about biosecurity, veterinary drug usage and production parameters were collected in 78 randomly selected farms from April and October 2024.

Results showed that almost all of pig farms (98.7%) used antiparasitics and 94.9% used antibiotics for preventive (58.7%) or curative (41.3%) purposes. Vaccination against swine erysipelas was practiced by only 24.4% of farmers. More than half of the farms (64.1%) in the study area had a biosecurity score below 50 out of 100 and the average biosecurity score was 47 (ranged 28-66). Biosecurity measure related to personnel and visitors ranked the lowest score (21, range 0-71) while measures applied during farrowing and suckling period (77, range 20-100), and those associated with the environment and region (77, range 40-100) ranked the highest. The biosecurity level was significantly influenced by the years of experience and the training in pig farming of interviewees, the herd size, the type of breeds reared and the production type (farrower, grower‐finisher or farrow‐to‐finish). Findings revealed a moderate association between number of farrowings per sow per year and lactation length. A correlation was found between biosecurity and lactation length. The high mortality rate (44.64 ± 24.60%) recorded on farms with a poor level of biosecurity compared to others (15.45 ± 11.94%) shows the importance of biosecurity in the prevention and control of diseases and the improvement of production.

The results of this study highlight the need for capacity building and awareness among farmers on the importance of implementing biosecurity measures for improving pig production.
