“…Several methods have been proposed to improve its utilization. These included physical, chemical, biological, or enzyme treatments [ 20 , 21 , 23 ]. Physical treatment, such as chopping, crushing, peeling, soaking, extruding, rolling, and steaming, can increase surface area, bulk density, and specific porosity to improve the digestive properties of the feed [ 21 , 62 ].…”

“…Anaerobic digestion of the crop residue as animal feed was regarded as a more feasible green solution, by producing lower GHG emissions than traditional open burning, land application, and biowaste composting [ 101 , 102 ]. However, in a review, Yanti and Yayota [ 23 ] cautioned that the higher fiber content in some agricultural by-products might lead to increased GHG emission, though these are arguably smaller than conventional methods of agricultural residual disposal. Optimizing tropical dairy cattle production, illustrated in Figure 1 , is crucial to dampen the effect of heat stress, while promoting sustainable farming with the strategic usage of agricultural by-products.…”

“…However, it’s utilization is still less than ideal, due to the lower nutritive values than imported feed and anti-nutritive factors, but are expected to be overcome with better processing methods and developmental strategies [ 21 ]. The strategic usage of these regional feedstuffs through ration balancing could reduce the impact of heat stress, methane emission, provide sufficient nutrients, and reduce feed cost by capping on the indigenous breeds’ ability to digest low-quality roughages [ 18 , 20 , 22 , 23 , 24 ]. Unless climate and nutrition challenges are addressed, losses in milk yield can reach up to 0.96 kg/day, with a depressed dry matter intake (DMI) of 0.85 kg, when dairy cattle are subjected to heat stress [ 22 , 25 ].…”

The demand and consumption of dairy products are expected to increase exponentially in developing countries, particularly in tropical regions. However, the intensification of dairy production to meet this increasing demand has its challenges. The challenges ranged from feed costs, resources, and their utilization, as well as the heat stress associated with rearing temperate–tropical crossbred cattle in the tropics. This article focused on key nutritional and environmental factors that should be considered when temperate–tropical crossbred cattle are used in the tropics. The article also describes measures to enhance the utilization of regional feed resources and efforts to overcome the impacts of heat stress. Heat stress is a major challenge in tropical dairy farming, as it leads to poor production, despite the genetic gains made through crossbreeding of high production temperate cattle with hardy tropical animals. The dependence on imported feed and animal-man competition for the same feed resources has escalated feed cost and food security concerns. The utilization of agricultural by-products and production of stable tropical crossbreds will be an asset to tropical countries in the future, more so when scarcity of feed resources and global warming becomes a closer reality. This initiative has far-reaching impacts in the tropics and increasingly warmer areas of traditional dairying regions in the future.

“…However, such agricultural by-products are highly fibrous, require longer fermentation and foment methane production 54,59,61 . The nutritional content can improve by degrading by-products cellulose before feeding ruminants; however, this process increases feeding costs [62][63][64][65][66] .…”

Livestock contributes to 14.5 percent of global greenhouse gas emissions, with ruminants being the largest contributor through enteric methane emissions. Although several strategies are available to mitigate livestock methane, no consensus exists on which methods are the most effective. Here, we projected by 2050 the impact of the most pragmatic strategies to reduce enteric methane, modelling cattle emissions. The projection shows that supplementing ruminant feed with anti-methanogenic seaweed and converting grassland into silvopasture offer the greatest potential to reduce emissions. A synergic combination of strategies can aid Europe and most of Asia to can reach ruminant carbon neutrality by 2035 and 2038, respectively. However, global cattle CO2-eq emissions will be reduced by no more than 34 percent by 2050, remaining far above the carbon neutrality target. Mitigation strategies alone are insufficient to lower emissions, and reducing the demand for ruminant products is also necessary – particularly in Africa and Western Asia.

Objective: This study aimed to explore and understand the source of fiber feed that is commonly used, and analyze the activities of fiber feed provision in dairy farms during the dry season, and investigate the fiber feed supply chain.Methods: This research was conducted on rural dairy farms in the Sub-district of Lembang located in West Bandung District. The data was collected by adopting an interview method with 50 farmers implements a purposive sampling technique to gather information regarding the provision pattern, supply chain of respective fibre feed. Samples of fiber feed in the dairy farms were taken using a simple random sampling technique. The data acquired is analyzed using descriptive analysis; these data consist of nutrient content of the fiber feed, provision pattern during the dry season, and the supply chain map of those fiber feed provisions.Results: The result reveals that the fiber feed that has been given to the dairy cows was cultivated grass, natural grass, legumes, and plant residue that entirely supplied from neighborhood area (≤ 30 km), which has different nutrient content. There are 16 provision patterns of fibre feed in the dry season, the vast majority of provision pattern was the combination of foraging from the farmer’s land and feed purchasing. By referring to the RFV calculations, legumes and vegetable waste have good quality. The fibre feed supply chain is relatively short, which is about (1-4 actors) due to its freshness and required no processing.Conclusions: In conclusions, the fibre feed that has been given to the dairy cows was cultivated grass, natural grass, legumes, and plant residue. There are 16 provision patterns of fibre feed in the dry season. The fibre feed supply chain is relatively short.
