“…Such an effect is explained by the high (99 ppm) As content in the BC and its toxic activity. In similar research conducted one year later, Evans et al [56] investigated 2% and 4% poultry litter BC feed amendment with lower toxic heavy metals content-birds fed with a 2% BC amendment had increased feed conversion ratio by 7% and birds fed with a 4% amendment had live weight gain decreased by 9%. Those negative effects had to be corrected with phytase inclusion to the feed.…”

When it comes to the use of biochar in agriculture, the majority of research conducted in the last decade has focused on its application as a soil amendment and for soil remediation. This treatment improves soil quality, increases crops yields, and sequestrates atmospheric carbon to the soil. Another widely studied aspect connecting biochar with agriculture is the composting processes of various agricultural waste with the addition of biochar. Obtaining the material via the pyrolysis of agricultural waste, including animal manure, has also been investigated. However, given the remarkable properties of biochar, its application potential could be utilized in other areas not yet thoroughly investigated. This review paper summarizes the last decade of research on biochar and its use in crop agriculture and livestock production. Knowledge gaps are highlighted, such as using biochar for the mitigation of odorous emissions from animal manure and by feeding the biochar to animals.

“…It is not surprising, then, that biochar addition to poultry diet can result in a wide range of outcomes. For example, biochar diet inclusion resulted in an increase in feed conversion ratio (FCR) and a decrease in body weight gain of chicken broilers [12,13]. Others have reported an improvement of production parameters (higher egg production and egg weight) and FCR for laying hens [14,15].…”

The aim of this research was to evaluate the effect of biochar diet supplementation for broiler chickens on (1) ammonia and odor emissions from manure, (2) feed conversion ratio and daily weight gain, and (3) selected meat quality and sensory parameters. Beechwood biochar (BC, 2 and 4%) and BC–glycerin–aluminosilicates mix (BCM, 3 and 6%) were tested as dietary additives. A total of 750 chicken broilers (Ross 308) were divided into five dietary groups with five replicates per group (n = 5, 30 birds in each replicate) and reared on a littered floor for 5 weeks. Both feed additives showed a significant reduction of ammonia emissions by up to 17%, while the reduction of odor emissions was not statistically significant. The feed conversion ratio increased by 8% for the highest concentration of the mixture. The change of the treated broilers’ average body weight ranged in the last week of the experiment from 0 to −7%, with the most negative effect for the highest dose of the mixture. Sensory analysis of the sous-vide cooked breasts showed no significant differences.

“…Poultry provides eggs and meat for human consumption. Evans et al (2017) revealed that 2% of broiler litter-based biochar supplemented in one-day-old broiler chicks' diet had no adverse effect on the chicks and resulted in similar weight gain and FCR compared with control feed. The results of an experiment in which poultry were fed biochar, bentonite or zeolite showed that biochar had the best granulation properties (1-4 mm) and moisture retention (85-90%).…”

“…Feed grade biochar is usually mixed with regular feed at approximately 0.1% to 4.0% of the daily feed intake (O'Toole et al, 2016). A number of studies have shown that adding biochar to feed can increase weight gain and feed intake (Evans, Boney, & Moritz, 2017;Phongphanith & Preston, 2016;Saroeun, Preston, & Leng, 2018); enhance animal health (Hien, Dung, Manh, & Le Minh, 2018); benefit nutrient intake; aid the detoxification of contaminants, pollutants and other toxins in feed; reduce antibiotics residues; and reduce enteric methane emissions (Leng, Inthapanya, & Preston, 2013;Winders et al, 2018;Khoa, Quang, Thang, Phung, & Kien, 2018). Table 4 summarizes the use of biochar in animal husbandry and the benefits observed in ruminants (cattle and goats), pigs, poultry (chicken and ducks) and fish, along with the corresponding raw materials and production conditions.…”

The production and application of biochar has become increasingly popular in the past 10 years. Biochar has similar characteristics to charcoal and activated charcoal: they are all pyrogenic carbonaceous matter derived from organic carbon-rich materials and produced by pyrolysis. Studies related to the incorporation of biochar in animal feed are limited. This review summarizes major studies related to the use of biochar as a feed additive for ruminants (cattle and goats), pigs, poultry (chickens and ducks) and fish. Documented positive responses to biochar supplementation include improved growth performance, blood profiles, egg yield, ability to resist pathogens including gut pathogenic bacteria and a reduction of methane production by ruminant animals. In addition, the high sorption capacity of biochar efficiently aids the removal of pollutants and toxins from animals' bodies as well as from farm environments. It is expected that there will be increasing use of biochar in animal farming. The potential use of biochar in the medical and human health sectors should also be explored.
