“…Air pollution in animal feeding environments had been widely recognized as a threat to animal health and safety, with ammonia and sulfur-containing compounds as two of the main noxious gases causing odor and environmental pollution problems on farms ( 26 ), and these contaminants could be detrimental to animal welfare. Han et al ( 27 ) found that probiotics could indirectly reduce these environmental pollutants in animal feces by improving the intestinal micro-ecology.…”

The aim of the experiment was to investigate the effects of a probiotic complex (PC) consisting of Bacillus subtilis, Clostridium butyricum and Enterococcus faecalis on productive performance, carcass traits, immune organ indices, fecal microbiota counts and noxious gas emissions in AA+ male broilers. Three hundred and sixty 1-day-old AA+ male broilers with similar body weight (44.77 ± 0.25) were randomly divided into 3 treatment groups of 6 replicates each, with 20 broilers in each replicate. The experimental groups consisted of a group fed a basal diet and groups fed basal diet supplemented with 0.1 and 0.2% PC. The results showed that the addition of PC had no significant effect (P > 0.05) on growth performance, and carcass traits of AA+ broilers during the experimental period (1–42 days of age). Dietary addition of PC significantly increased the thymus index of AA+ broilers (P < 0.05), reduced the number of E. coli and Salmonella in feces (P < 0.01) and reduced the concentrations of fecal NH3 and H2S emissions (P < 0.01). Furthermore, birds fed 0.2% PC diet had the highest number of fecal Lactobacillus counts. Results indicate that probiotic complex consisting of Bacillus subtilis, Clostridium butyricum and Enterococcus faecalis enhances immune organ development, reduces the number of E. coli and Salmonella in feces, increases the number of Lactobacillus and reduces NH3 and H2S emissions in feces. This trial provides a theoretical basis for the use of probiotic complexes in broiler production.

“…As shown in the previous sections, UV-A photocatalysis can have a role in each of these principles. Ni et al [62,63] summarized some observational studies that confirmed air toxicity could result in animal deaths or injuries. The reported primary pollutants are NH 3 , PM, H 2 S, bacteria and endotoxins.…”

Ultraviolet (UV)-based photocatalysis has been the subject of numerous investigations focused on mitigating undesirable pollutants in the gas phase. Few works report on applications beyond the proof of the concept. Even less is known about the current state of the art of UV photocatalysis in the context of animal agriculture. A growing body of research published over the last 15 years has advanced the knowledge and feasibility of UV-A photocatalysis for swine and poultry farm applications. This review paper summarizes UV-A photocatalysis technology’s effectiveness in mitigating targeted air pollutants in livestock and poultry farms. Specifically, air pollutants include odor, odorous VOCs, NH3, H2S and greenhouse gases (CO2, CH4, N2O). We trace the progression of UV-A photocatalysis applications in animal farming since the mid-2000 and developments from laboratory to farm-scale trials. In addition, this review paper discusses the practical limitations and outlines the research needs for increasing the technology readiness and practical UV application in animal farming.

“…Multiple parameters influence environmental conditions in broiler houses including temperature, humidity, air movement (speed), harmful gases, and particulate matter ( PM ) ( Ni et al, 2021 ). Air temperature and relative humidity are environmental factors that are significantly related to broiler mortality, because birds do not have sweat glands and are highly sensitive to heat stress ( Dawkins et al, 2004 ; Nawab et al, 2018 ).…”
