“…The influence of wind speed produced by a blower is obtained due to that is stable and evenly distributed throughout the drum area due to the arrangement of Strato-tech panel control, which is controlled based on the level of age suitability and weight of the chicken. This result follows research conducted by [31] that the most substantial influence on chicken weight gain is feed consumption, which is influenced by the environment. Also, weight gain is closely related to feeding the right amount and food quality.…”

In closed-house enclosures with various sensors, air quality parameters are sometimes not monitored regularly, especially during colder weather. Standard provisions are often not considered because reducing operating costs is cheaper. To produce these parameters, special efforts are needed to ensure temperature, relative humidity control, and simultaneous release of NH3 and CO2 gases. The cost of broiler chicken production reaches 70% from feed, so high feed use reduces farmer income. To help farmers reduce production costs, the Palopo Government provides equipment rocks to broiler chicken farmers as stators-tech tools, an element of wind speed in the cage. Data was collected directly from blower speed measurements produced by stators-tech and weighing body weight growth during maintenance. The results obtained by farmers using stator-tech control tools assisted by the Palopo City Government showed very significant results by getting an IP score of 505 (prime) because the effect of strong winds from blowers can be reduced by the tool, even though the mortality rate is 3.65%.

“…As such, Campylobacter is commonly isolated from poultry, including chickens and turkeys, but also other domestic and wild avian species, such as crows, ducks, quail, and starlings ( Jonaidi-Jafari et al, 2016 ; Weis et al, 2016 ). Even though the naturally high body temperature (40–42°C) ( Johnston et al, 2016 ; Hamrita and Conway, 2017 ) of avian species provides an ideal environment for Campylobacter growth, the bacterium also commonly colonizes domestic livestock, including cattle, goats, pigs, and sheep ( Manyi-Loh et al, 2016 ). For example, in beef and dairy cattle fecal samples in Finland, 31.1% of samples contained Campylobacter spp.…”

Campylobacter jejuni is the leading cause of bacteria-derived gastroenteritis worldwide. In the developed world, Campylobacter is usually acquired by consuming under-cooked poultry, while in the developing world it is often obtained through drinking contaminated water. Once consumed, the bacteria adhere to the intestinal epithelium or mucus layer, causing toxin-mediated inhibition of fluid reabsorption from the intestine and invasion-induced inflammation and diarrhea. Traditionally, severe or prolonged cases of campylobacteriosis have been treated with antibiotics; however, overuse of these antibiotics has led to the emergence of antibiotic-resistant strains. As the incidence of antibiotic resistance, emergence of post-infectious diseases, and economic burden associated with Campylobacter increases, it is becoming urgent that novel treatments are developed to reduce Campylobacter numbers in commercial poultry and campylobacteriosis in humans. The purpose of this review is to provide the current status of present and proposed treatments to combat Campylobacter infection in humans and colonization in animal reservoirs. These treatments include anti-Campylobacter compounds, probiotics, bacteriophage, vaccines, and anti-Campylobacter bacteriocins, all of which may be successful at reducing the incidence of campylobacteriosis in humans and/or colonization loads in poultry. In addition to reviewing treatments, we will also address several proposed targets that may be used in future development of novel anti-Campylobacter treatments.

“…Ensuring a consistent air velocity throughout the animal-occupied zone (AOZ cial to prevent animals from migrating to areas with better ventilation. The conce of birds in specific areas with improved airflow can lead to heightened mortalit Maintaining an air velocity of approximately 0.3 m s −1 during the first two weeks erally recommended, increasing to 0.5 m s −1 in the third week, 1 m s −1 in the fourt and above 1 m s −1 afterward [23][24][25]. In hot weather conditions, when temperatu elevated, a higher air velocity of approximately 2.5 m s −1 is necessary to provide a cooling for the chickens [26].…”

In recent years, computational fluid dynamics (CFD) has become increasingly important and has proven to be an effective method for assessing environmental conditions in poultry houses. CFD offers simplicity, efficiency, and rapidity in assessing and optimizing poultry house environments, thereby fueling greater interest in its application. This article aims to facilitate researchers in their search for relevant CFD studies in poultry housing environmental conditions by providing an in-depth review of the latest advancements in this field. It has been found that CFD has been widely employed to study and analyze various aspects of poultry house ventilation and air quality under the following five main headings: inlet and fan configuration, ventilation system design, air temperature–humidity distribution, airflow distribution, and particle matter and gas emission. The most commonly used turbulence models in poultry buildings are the standard k-ε, renormalization group (RNG) k-ε, and realizable k-ε models. Additionally, this article presents key solutions with a summary and visualization of fundamental approaches employed in addressing path planning problems within the CFD process. Furthermore, potential challenges, such as data acquisition, validation, computational resource requirements, meshing, and the selection of a proper turbulence model, are discussed, and avenues for future research (the integration of machine learning, building information modeling, and feedback control systems with CFD) are explored.
