Special Issue Information

Dear Colleagues,

Although poultry production provides the most efficient, affordable, and nutritious high quality animal proteins (egg and meat) and supports the livelihood and food security of billion of people worldwide, it is facing several substantial challenges. Amongst these challenges is feeding the future and satisfying the increased demand for animal proteins, which is driven by projected growth in human population and economy, and the need to adapt to harsh environmental conditions (droughts, global warming, floods, etc.), limited and already scarce natural resources (water, land, energy), and changing consumer preferences in NAE era.

In this special issue, we welcome colleagues to submit their ongoing research in the form of research paper, review, case report, or short communication to Poultry focusing on the areas most challenging to poultry production sustainability. This includes, but is not limited, stress (heat, transport, cold, etc.), meat quality, bone quality/health, gut health, welfare, and reproductive health/performance. Poultry research encompasses all avian species of relevance, including broilers, turkeys, and layers are welcome.

In the past decade, the withdrawal of antibiotics used as growth promoters (AGP) has increased some poultry industry challenges, such as the rise of intestinal diseases. Experts advocate that AGPs improve performance due to the modulation of the intestinal microbiota, with resulting anti-inflammatory effects. However, the impact and interactions of AGPs with the host intestinal immune system are still unknown, which represents issues in developing effective alternatives for AGPs. Therefore, this study was aimed at better understanding the potential mechanism of action of bacitracin used as AGP and its impacts on the intestinal immune system. Ninety day-of-hatch chickens were randomly assigned to two treatments with three repetitions of fifteen birds, a control (CNT) group with a corn/soybean meal standard diet, and a control diet supplemented with 50 g/ton of feed of bacitracin (BMD). The cytokines’ and chemokines’ production (IFN-α, IFN-γ, IL-16, IL-10, IL-21, IL-6, M-CSF, MIP-3α, MIP-1β, VEGF and CCL-5) were assessed in the jejunum and ileum at 14, 21, 28 and 36 days of age by using a chicken-specific cytokine/chemokine peptide ELISA array. Broilers with BMD supplementation were found to have a lower production of IL-16, IFN-γ, M-CSF, IL-21, MIP-1β and VEGF in the jejunum at 14 d. However, from 21 through 36 days, the effect of BMD on cytokine production in the jejunum was negligible except for CCL-5, which was reduced at D36. In the ileum, BMD effects on the cytokine profile started at 28 d, when BMD-supplemented broilers showed a reduced IL-6 production level. At day 36, BMD reduced IL-16 and MIP-3α production but increased VEGF concentration in the ileum tissue. The present study demonstrated that the use of bacitracin as an AGP modulates the small intestine immune system, especially in the first phase of the broiler’s life (up to 14 days). Moreover, BMD anti-inflammatory effects include not only innate immunity but also seemed to influence the development of the adaptive immune response as seen by the decreased production of IL-21 and IL-16. These results demonstrate that a commonly used AGP in broiler feed had a local anti-inflammatory effect. Full article

Disease prevalence and seasonal outbreaks are challenging the poultry industry in Ethiopia. Proper and sustainable implementation of biosecurity practices is important to reverse such problems. This study was conducted in commercial poultry farms in two zones of Ethiopia to investigate farm characteristics, implementation of biosecurity practices, and biosecurity status (BS) using a structured questionnaire. The variables were grouped into three biosecurity factors, including conceptual, structural, and operational biosecurity, based on their homogeneity. Descriptive and inferential statistics were used to summarize the results. Most commercial farms were owned by males (69.7%). The majority of the farms (40.3%) were located at a distance <50 m from residential areas. Farm owners do not provide biosecurity training to their employees (68.8%), which results in poor biosecurity implementation. The mean conceptual, structural, and operational BS were 50.4 ± 11.62, 63.27 ± 10.51, and 44.69 ± 13.04, respectively, indicating operational biosecurity measurements were less implemented. Overall, the BS indicated that 40.7% of the farms have BS < 50% questing for interventions. Farm characteristics and biosecurity measurements were positively associated with BS, which shows substantial room for improvement. Owners’ education, occupation, experience, farm flock size, and training were significantly associated with BS (p < 0.05). A disease prevention strategy through biosecurity improvement is an economical means for controlling poultry disease prevalence. Full article
