With global population growth, livestock production must be intensified with reduced environmental impact. The benefits of legume-grass intercropping are well-documented; however, no studies have evaluated ruminal fermentation and digestive kinetics. Pigeon pea, a legume intercropped with tropical grasses, ...

Pasture management is pivotal for enhancing soil organic carbon (SOC) storage in tropical grasslands, yet SOC recovery is often considered merely as the replenishment of historical losses following land-use change. It remains unclear whether managed Ferralsols can surpass the SOC stocks of&#...

This study evaluated the effects of five pasture-based production systems on the carcass and meat quality traits, as well as the methane (CH4) emissions intensity of male Nellore steers per kg of carcass under tropical conditions. Over two years (2019–2021), uncastrated male steers ...

Glass fertilizers (GF) emerge as an alternative to traditional fertilizers, due to their advantages, such as the possibility of incorporating several nutrients into their structure and the ability to control their dissolution through compositional adjustments. By varying the concentrations of gla...

Tons of alum sludge (AS) are produced worldwide during the water treatment process, and the reuse of this waste could contribute to the circular economy of water treatment companies. The chemical composition of AS makes it a promising raw material for the development of zeolit...

Abstract: Given the growing concern about greenhouse gas (GHG) emissions, sustainable nutritional strategies have gained importance in ruminant production. The inclusion of organic additives in the diet of ruminants may improve animal performance and reduce environmental impacts, especially when appli...

Abstract: Early modulation of the ruminal microbiota has been explored as a strategy to improve digestive efficiency and mitigate methane production in ruminants. This approach depends on the concept of early-life programming, which recognizes the microbial plasticity during initial developmental ...

Including fat thickness as a covariate in the regression model used to calculate residual feed intake (RFI) could help preserve carcass quality traits, such as marbling, flavour and juiciness, by accounting for variation in fat deposition. This study aimed to: (1) investigate the b...

The continuous growth in both the number of phenotypic records and the range of traits included in beef cattle genetic evaluations poses substantial statistical and computational challenges for the estimation of genetic and residual (co)variance matrices required for breeding value estimation.&#x...
