Article Synopsis
- The study analyzed three local chicken ecotypes in Ghana—Interior Savannah, Forest, and Coastal Savannah—using morphological traits and genetic data.
- Significant effects of ecotype and sex were found on body weight, with the Interior Savannah chickens being the heaviest.
- Despite exhibiting high genetic diversity, the three ecotypes showed similar morphological traits, and limited instances of heat-resistant feather phenotypes were noted.
Newcastle disease (ND) is a highly contagious viral disease that constantly threatens poultry production. The velogenic (highly virulent) form of ND inflicts the most damage and can lead to 100% mortality in unvaccinated village chicken flocks. This study sought to characterize responses of local chickens in Ghana after challenging them with lentogenic and velogenic Newcastle disease virus (NDV) strains.

- The study focused on Animal African Trypanosomiasis (AAT), a major disease impacting livestock in sub-Saharan Africa, and examined the presence of trypanosomes in cattle over two years in Ghana, comparing an AAT-endemic region (Adidome) to a non-endemic area (Accra).
- Researchers collected blood samples from selected cattle at regular intervals and used advanced techniques like nested PCR and sequencing to identify and measure the levels of trypanosome DNA, finding that many cattle were infected with multiple species, particularly T. vivax.
- The study concluded that despite most cattle having low levels of infection, the findings emphasized the need for ongoing monitoring of tryp
This study was carried out to assess the response of three Ghanaian local chicken ecotypes to LaSota (lentogenic) and virulent field strains of Newcastle disease virus (NDV). Local chickens sampled from the Interior Savannah (IS), Forest (FO) and Coastal Savannah (CS) agro-ecological zones were bred and their offspring were challenged with LaSota NDV at 4 weeks of age. The LaSota challenge was replicated four times with different chicken groups.

To investigate the genetics of Ghanaian local chicken ecotypes to Newcastle disease virus (NDV), in this study, three popular Ghanaian chicken ecotypes (regional populations) were challenged with a lentogenic NDV strain at 28 days of age. This study was conducted in parallel with a similar study that used three popular Tanzanian local chicken ecotypes and after two companion studies in the United States, using Hy-line Brown commercial laying birds.
