Rajpoot, S.K. et al. (2024). BiocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges.

The prosperity of animal husbandry relies on good practices, including scientific feeding that incorporates essential nutrients and supplements. Biochar, a novel and relatively unexplored additive, is gaining attention for its potential benefits in this field. Produced through the pyrolysisPyrolysis is a thermochemical process that converts waste biomass into bio-char, bio-oil, and pyro-gas. It offers significant advantages in waste valorization, turning low-value materials into economically valuable resources. Its versatility allows for tailored products based on operational conditions, presenting itself as a cost-effective and efficient More of biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More at around 700°C with minimal oxygen, the quality of biochar is influenced by the type of biomass, the duration, and the temperature of the pyrolysis process. These factors determine its physical and chemical properties, such as elemental composition, surface area, and porosityPorosity of biochar is a key factor in its effectiveness as a soil amendment and its ability to retain water and nutrients. Biochar’s porosity is influenced by feedstock type and pyrolysis temperature, and it plays a crucial role in microbial activity and overall soil health. Biochar More.

Recent studies have shown that biochar, when included as a feed additive at levels of 0.5–3%, can enhance the production performance and health of ruminants. It has been found to improve feed intake, body weight gain, feed conversion ratio, immune response, carcass quality, and overall animal product quality. The beneficial effects of biochar are attributed to its adsorption capabilities, which help detoxify mycotoxins in feed, regulate plant toxins, and attract pollutants. Additionally, biochar promotes the growth of beneficial gut microorganisms in ruminants.

Despite these promising findings, more research is needed to fully understand the usefulness of biochar in animal production. Some studies have shown inconsistent results, highlighting the need for further investigation into the safety, economic feasibility, and long-term effects of biochar as a feed additive. As research progresses, biochar could become a valuable component of sustainable animal husbandry practices.
