Summary: Two experiments were conducted to study the effects of variable grass silage quality and concentrate feed supplementation on dairy cow responses. The results showed that dairy cows responded to changes in silage harvesting time and concentrate amount, with a decrease in silage digestibility reducing the effects of additional concentrate.

Summary: The digestion capacity and methane production of llama rumen inoculum were compared to that of sheep rumen inoculum using fescue and paspalum hay as substrates. While llama rumen inoculum showed better dry and organic matter digestibility at 24 hours, sheep rumen inoculum performed better at 48 hours. Both species had similar methane production levels.

Summary: This study evaluated the influence of forage species adapted to the tropical region of Ecuador on gas production, digestion, ruminal fermentation, and enteric methane. Certain forage species were found to reduce enteric methane production, but also potentially decrease organic matter fermentation in the rumen.

Summary: Livestock grazing is crucial for grassland maintenance and animal production worldwide. Understanding the effects of grazing on nutrient digestibility, energy utilization, and methane emissions in sown pasture vs native pasture is important for sustainable grassland-livestock interactions.

Summary: This study investigated residual feed intake, volatile fatty acid production, and enteric methane emissions in growing Pelibuey sheep. The results showed that low residual feed intake lambs had lower intake of dry matter, organic matter, crude protein, and neutral detergent fiber, resulting in lower methane emissions.

Summary: This study examines the farm-level greenhouse gas (GHG) emissions of sheep production systems relying on transhumance practices in arid and continental conditions, using Turkey as an example. The results show that the transhumance farms have lower total farm output and CO2e emissions per unit of output compared to semi-intensive farms. However, the net emissions from land use are higher for transhumance farms. This study provides valuable insights into the GHG emission impact of different sheep production systems in continental rangelands in Turkey.

Summary: The research found that the addition of 20% and 40% of Acacia mearnsii negatively affected the digestion of nutrients in ruminants, but reduced methane production. This may be associated with the low activity of microorganisms towards the substrate due to the possible tannin/nutrient complex.

Summary: This study assessed the impacts of animal and feed factors, ambient temperature, and climatic region on rumen digestibility in ruminants. Results showed that increasing temperatures can reduce the digestibility of feeds, with a greater effect seen in roughages in tropical and arid climates.

Summary: Legume forages play a crucial role in ruminant livestock production systems, as they have higher quality compared to grasses, improving intake and food conversion efficiencies and reducing environmental impacts. Bioactives such as condensed tannins also enhance energy and protein use efficiency in ruminants, with grazing tannin-containing legumes reducing bloat and improving meat quality.

Summary: The inclusion of Acacia mearnsii leaves in ruminant's diets has been found to reduce the population of protozoa and methane production while not affecting ruminal degradation kinetics, nutrient digestibility, and microbial protein production. Up to 15% of A. mearnsii leaves can be recommended as a supplement in high-fiber diets without adverse effects.

Summary: The use of paulownia leaves silage (PLS) as a feed can reduce methane emission and improve milk quality in dairy cows. PLS affects ruminal fermentation, microbial populations, and fatty acid proportions in ruminal fluid and milk.

Summary: This study found that there were no significant differences in forage productivity and animal performance under different forage mixtures, but the mixture with higher plant diversity had a slight advantage in digestibility and methane emissions.
