My intrinsic interest in animal production and science motivated me to study Animal Science in a renowned institution in Brazil. Due to the importance of poultry industry in providing high quality and affordable food products, I have focused my career studying poultry science, in order to improve poultry production, taking into account animal welfare, sustainability, and food security.
During my Master’s degree at Mississippi State University, I studied the effects of alternatives to antibiotic growth promoters on roosters’ semen microbiota, which can present a threat to human health due to the transmission of pathogenic bacteria to the hens, chicks and ultimately humans.
In my Ph.D., I will be evaluating the welfare and health and slow and fast-growing strains of broiler chickens, due to the disorders and diseases associated with genetic selection for growth. Moreover, there is increasing consumer preference for products that are naturally produced, free of antibiotics, and promote the welfare of the birds. This has led to the increasing demand for slow-growing strains of broilers chickens. However, there is scarce information about the use of these genotypes in traditional production systems without outdoor access. To evaluate the welfare of slow and fast growing-strains of broilers, different parameters will be measured, including behaviour, skeletal abnormalities, meat quality, and cardiovascular disorders. This study can be further exploited to improve poultry production by optimizing the welfare and health of broiler chickens in commercial poultry houses.
