In Northern Senegal, traditional cattle management systems (TRAD) which depend on natural forages coexist with intensified systems (INT) which rely on periodic supplementation with crop residues and local concentrates. This study aims to estimate the effects of seasons and management systems on the methane emissions of Gobra zebu, in relation to the diet's chemical composition and feed intake. Six Gobra zebu cows per management system were individually monitored over 10 months, diet and faeces were sampled each season and their chemical composition and dry matter intake (DMI) were predicted by near infrared spectroscopy.

- The study examined how Acacia nilotica, a tropical plant with hydrolyzable tannins, affects rumen fermentation and methane production in sheep, using both leaves and pods of the plant.
- Various combinations and proportions of A. nilotica and other tannin-rich plants were tested via in vitro incubations to analyze their impact on methane emissions and fermentation efficiency.
- Results showed that incorporating A. nilotica significantly reduced methane production (up to 64%) while also decreasing volatile fatty acid production, highlighting the potential of this plant for improving feed efficiency in livestock.
