Effects of walnut shell and chicken manure biochar on in vitro fermentation and in vivo nutrient digestibility and performance of dairy ewes

Biochar as a feed supplement for nutrient digestibility and growth performance of Catla catla fingerlings

“…The fundamental role of charcoal is to positively affect the functions of digestion and absorption of nutrients ( Jahan et al, 2014 ) explained that better nutrient utilization by using activated charcoal supplemented feed is attributed to the growth-promoting microbes present along the gastro-intestinal tract of animals. In goats, ( Van et al, 2006 ) and ( Mirheidari et al, 2019 ) noticed improved protein digestibility by adding bamboo charcoal and chicken manure biochar (1.5 %) as a dietary additive, respectively. Similarly, lambs also experienced changed digestive and rumen functions by consuming charcoal-based diets ( Poage et al, 2000 ).…”

Biochar for agronomy, animal farming, anaerobic digestion, composting, water treatment, soil remediation, construction, energy storage, and carbon sequestration: a review

“…In comparison with the control, adding 1% walnut shell biochar and 1.5% chicken manure biochar to the in vitro study reduced methane emissions, total volatile fatty acid generation, and ammonia N, while raising pH. In in vivo research, supplementing dairy ewes with biochar at higher concentrations enhanced milk production, milk protein, solids non-fat portion, blood glucose, dry matter, and fibre digestibility rates, and decreased gas emissions (Mirheidari et al 2019 ). Silivong and Preston determined that supplementing goats diets with 1.1% biochar increased their weight by 8.9%, improved their feed conversion ratio from 15.5 to 11.4, and improved their digestibility (Silivong and Preston 2015 ).…”
