The effect of supplementing a mixed rice straw and tropical grass diet with legume as a nitrogen (N) source on intake, digestibility, rumen ammonia and microbial protein production was evaluated in Bos indicus cattle. Four rumen-cannulated steers were used in a crossover design with two diets and two periods. The diets were T1 = 40% rice (Oryza sativa L.) straw + 60% grass (Brachiaria spp. cv. Mulato II hybrid) and T2 = 40% rice straw + 30% grass + 30% legume (Stylosanthes guianensis cv. CIAT 184) on DM basis. Supplementation with legume doubled (P < 0.01) rice straw and total N intake, and increased total DM intake by 32%. It did not affect the DM, organic matter, neutral detergent fibre and acid detergent fibre digestibility (P > 0.05) but did increase (P < 0.05) N digestibility. Faecal N and total N outputs from T2 cattle were higher (P < 0.05) than T1 cattle, but urinary N output did not differ between diets (P > 0.05). N retention in T2 cattle was improved by 83% (P < 0.05) compared with T1 cattle. Rumen ammonia concentration, microbial protein production and efficiency of microbial protein production were improved (P < 0.05) when the legume forage was included in the straw–grass diet. We conclude that when a mixed rice straw and fresh grass diet is supplemented with ~30% legume (DM basis), significant improvements in DM and N intake can be achieved.

Protein Supply

Feeding lambs diets formulated to be synchronous in terms of hourly energy and protein supply to the rumen has been reported to improve the efficiency of energy utilisation (Richardsonet al.1999). In a previous study Sinclairet al.(1995) reported that the efficiency of microbial protein production was improved when animals were fed a synchronous diet. The objectives of the present study were to investigate whether the changes in metabolism reported by Richardsonet al.(1999) may be related to rumen microbial protein production and diet digestibility.

The object of this present work was to determine the effects of supplementation with pellets containing royal poinciana seed meal (PEREM) on feed use, ruminal fermentation efficiency, microbial protein synthesis, blood metabolites and mitigation of methane (CH4) emissions in cattle. The animals used in this experiment were four male Thai native beef cattle (Bos indicus) with initial body weights (BWs) of 125 ± 5.0 kg. Each of the animals were randomly assigned to receive PEREM doses at 0, 50, 100 and 150 g/d, respectively, according to a 4 × 4 Latin square design. Concentrates were fed at 0.5% BW daily, and rice straw was fed ad libitum. There were no significant differences (p > 0.05) on intakes of rice straw, concentrate and total diet. The intake of nutrients did not change among the levels of PEREM supplementation (p > 0.05), except for an intake of crude protein, which was linearly enhanced when increasing the dose of PEREM (p < 0.05). The inclusion of different doses of PEREM did not adversely affect the digestibility of dry matter, organic matter, crude protein, neutral detergent fiber and acid detergent fiber (p > 0.05). Adding various doses of PEREM did not alter ruminal pH and ruminal temperature, while concentrations of ammonia-nitrogen were significantly increased with an increased dose of PEREM supplementation (p < 0.01). The increasing doses of PEREM linearly reduced protozoal numbers (p < 0.01), with the lowest concentration when PEREM was added at 150 g. PEREM supplementation did not change (p > 0.05) the concentration of acetic acid or butyric acid or the ratio of acetic acid to propionic acid. Nevertheless, the total volatile fatty acid and propionic acid content were changed among PEREM levels (p < 0.05), which were linearly increased with an increasing dose of PEREM. At 4 h post feeding, the CH4 concentrations in the rumen of the animal were linearly reduced when the dose of pellets was increased (p < 0.01). In addition, the inclusion of PEREM did not adversely affect other blood metabolites, namely total protein, creatinine and albumin (p > 0.05). Furthermore, microbial crude protein and efficiency of microbial N synthesis were linearly enhanced when increasing levels of PEREM were added. The feeding of PEREM at 150 g/d might be an alternative with the potential to improve rumen fermentation efficiency and reduce the environmental effects produced by ruminants.

Abstract Purpose Renewable energy produced from wind turbines and solar photovoltaics (PV) has rapidly increased its share in global energy markets. At the same time, interest in producing hydrocarbons via power-to-X (PtX) approaches using renewables has grown as the technology has matured. However, there exist knowledge gaps related to environmental impacts of some PtX approaches. Power-to-food (PtF) application is one of those approaches. To evaluate the environmental impacts of different PtF approaches, life cycle assessment was performed. Methods The theoretical environmental potential of a novel concept of PtX technologies was investigated. Because PtX approaches have usually multiple technological solutions, such as the studied PtF application can have, several technological setups were chosen for the study. PtF application is seen as potentially being able to alleviate concerns about the sustainability of the global food sector, for example, as regards the land and water use impacts of food production. This study investigated four different environmental impact categories for microbial protein (MP) production via different technological setups of PtF from a cradle-to-gate perspective. The investigated impact categories include global warming potential, blue-water use, land use, and eutrophication. The research was carried out using a life cycle impact assessment method. Results and discussion The results for PtF processes were compared with the impacts of other MP production technologies and soybean production. The results indicate that significantly lower environmental impact can be achieved with PtF compared with the other protein production processes studied. The best-case PtF technology setups cause considerably lower land occupation, eutrophication, and blue-water consumption impacts compared with soybean production. However, the energy source used and the electricity-to-biomass efficiency of the bioreactor greatly affect the sustainability of the PtF approach. Some energy sources and technological choices result in higher environmental impacts than other MP and soybean production. When designing PtF production facilities, special attention should thus be given to the technology used. Conclusions With some qualifications, PtF can be considered an option for improving global food security at minimal environmental impact. If the MP via the introduced application substitutes the most harmful practices of production other protein sources, the saved resources could be used to, for example, mitigation purposes or to improve food security elsewhere. However, there still exist challenges, such as food safety–related issues, to be solved before PtF application can be used for commercial use.

Enhanced cellulolytic activity in the rumen and improved balance between amino acids and energy have been suggested to increase silage dry matter intake in cows given high quality protein supplements. The objective of this study was to investigate the effects of casein infused continuously into the rumen, duodenum or both on forage intake, milk yield, milk composition and microbial protein production.
