Assessment of GHG emissions in dairy production systems based on existing feed resources through the model under different climatic zones of Bangladesh and their mitigation options.

Objective: The current study evaluated the greenhouse gas (GHG) emissions of dairy cattle through the Global Livestock Environmental Assessment Model model and illustrated potential mitigation strategies by modifying nutrition interventions.

Materials And Methods: A semi-structural questionnaire was developed to calculate dairy animal GHG emissions. This study comprised 40 farmers from four districts: river basin (Pabna), drought-prone (Chapainobabganj), floodplain (Nilphamari), and saline-prone (Sathkhira) areas.

Quality assessment and feeding impact of Moringa feed on intake, digestibility, enteric CH emission, rumen fermentation, and milk yield.

Objective: This experiment was designed to assess the quality and to evaluate the feeding impact of moringa feed on intake, digestibility, rumen fermentation, methane (CH) production, and milk yield.

Materials And Methods: According to body weight and exit-entry average daily milk production, fifteen BLRI cattle breed-1 lactating cows of 3rd or 4th stage of parturition with wk 3 and 4 of calving were selected and were equally and randomly distributed into three dietary groups. One group of cows was fed a control diet (T) consisting of 1:1 dry matter (DM) of Napier silage and conventionally mixed concentrate.
