Summary: The study found that crude glycerin can replace ground corn without affecting feeding behavior in lambs, but it may decrease feeding efficiency. Cottonseed cake as a protein source can completely replace soybean meal without affecting the intake efficiency in feedlot lambs.

Summary: This study identified and evaluated differences in microbiome compositions of the ileum and ceca of white leghorn genetic strains from 1940 and 2016. The research found that genetic lineage did not significantly affect microbiome diversity, but genetic makeup in combination with nutritional composition influenced the microbiota in the ceca and ileal of the hens.

Summary: This study evaluated the effects of chitosan on meat quality in feedlot lambs. The results showed that the use of chitosan did not affect feed intake, body weight gain, and feed conversion in the lambs. However, it did have a linear effect on meat pH0 h and increased the content of unsaturated fatty acids in the meat at a specific dosage.

Summary: The ratio of forage to concentrate in cattle feeding has a significant impact on the composition of the rumen microbiota and methane production. This study investigated the relationship between microbial abundances and methane emissions, and identified potential biomarkers, in cattle fed extreme diets of poor quality grass or high concentrate total mixed ration. The diet had a significant effect on methane yield and the abundance of microbial genera. The study highlights the contrast in microbiota controlling methane yield between animals fed different diets, emphasizing the need to consider this when developing strategies to reduce methane emissions.

Summary: The water balance and urinary parameters of lambs fed diets containing cactus cladodes varieties were evaluated. The results showed that diets with Miuda or OEM cactus led to a decrease in voluntary water intake, while Miuda cactus caused urine alkalinization and reduction in calcium excretion. The diets with OEM cactus led to increased oxalates intake and urinary volume. Overall, regardless of the variety, cactus cladodes diets reduced urinary concentrations of urea, creatinine, total proteins, calcium, and phosphorus.

Summary: This study evaluated the bacterial species and diversity of methanogenic Archaea in the solid fraction of ruminal content in response to different diets. The results showed that cellulolytic bacteria were predominant, with different diets affecting the abundance of different bacterial species. Additionally, feeding soybean seemed to reduce the number of methanogenic Archaea in the rumen.

Summary: The sustainable cultivation of triangle sail mussel Hyriopsis cumingii is hindered by the lack of a suitable diet. Through single factor experiments, it was found that Cyclotella sp. was the optimal microalgal diet for H. cumingii, followed by Scenedesmus dimorphus.

Summary: This study evaluates the effectiveness of different additives in preventing urolithiasis in lambs fed a high-concentrate diet. The results show that the additives do not affect the lambs' performance and health, and although they acidify urine, they do not completely prevent the formation of urolithiasis.

Summary: This study investigated the effects of feeding lambs with different levels of Acacia mearnsii leaf-meal (AMLM) on meat quality parameters, including fatty acid composition, color, antioxidant activity, myoglobin and lipid oxidation, protein oxidation, and instrumental tenderness. The results showed that dietary addition of AMLM improved the fatty acid composition, tenderness, and shelf-life of lamb meat.

Summary: The objective of this study was to evaluate the effects of corn hybrid and processing methods on intake and digestibility of nutrients, rumen fermentation and blood metabolites of steers fed no-forage finishing diets. The study found that there were interactions between corn hybrid and processing methods on intake, digestibility, rumen pH and ammonia nitrogen. Additionally, the processing method influenced starch consumption and fecal pH.

Summary: The study aimed to investigate the effects of tannins on plant protein digestion in sheep by combining in vivo and in vitro approaches. The results showed that tannins reduced the production of protein degradation products and increased the abundance of RuBisCo protein. This protective effect was observed during early-stage intestinal digestion but not in the late-stage.

Summary: This study aimed to investigate the effect of providing rumen liquid inoculum from adult cows to pre-weaning calves. The results showed that the inoculum enhanced the maturation of rumen bacterial communities in calves, but its effect on eukaryotic communities was unclear and requires further investigation.

Summary: This study investigated the degradation of tannin-rich plants in the rumen and their effects on microbial colonization. The results showed that the presence of tannins interferes with microbial colonization and the total amount of hydrolysable and condensed tannins in a plant determines its interaction with rumen microbes, affecting degradation and fermentation processes.

Summary: The study evaluated the effects of high-starch or starch and oil-supplemented diets on rumen and faecal bacteria, linking these changes to milk fatty acid profiles. Different diets influenced the bacterial structures in both rumen and faeces, with specific bacterial taxa showing correlations with certain fatty acids in milk. The research emphasizes the importance of diet in shaping the bacterial community structure and its potential impact on milk quality.

Summary: Some antimethanogenic feed additives for ruminants can lead to the accumulation of rumen dihydrogen (H2), which may affect optimal fermentation. However, combining an H2 acceptor with a methanogenesis inhibitor can decrease rumen H2 build-up and improve beneficial metabolite production for the host ruminant.

Summary: Most mitigation strategies to reduce enteric methane production in the rumen result in an excess of rumen dihydrogen that is not utilized efficiently. This study investigated the potential of phenolic compounds to act as hydrogen acceptors, thereby improving rumen fermentation and reducing methane production. The results showed that Asparagopsis taxiformis effectively inhibited methane production, increased hydrogen accumulation, and improved rumen fermentation in goats.

Summary: The inhibition of methane emissions in livestock does not result in consistent improvements in production, and the expected improvement in net energy for production is small and difficult to detect. Therefore, the claim that enteric methane inhibition will lead to more feed-efficient animals is not supported.

Summary: Protozoa, including entodiniomorphs and holotrichs, play a major role in the microbial biomass of the rumen microbiome. However, their specific biological and metabolic contributions to rumen function have not been well described. By using metaproteomics, this study reveals the specific metabolic niches occupied by protozoa in relation to their microbial co-habitants in the rumen fluid of cattle and goats fed varying diets.

Summary: In this study, dairy cows with different susceptibility to mastitis were examined to explore the relationships between microbiota composition and various factors in different body sites. The results showed that each body site harbored a specific microbial community that changed over time. There was a significant sharing of microbes between anatomical sites within each animal, but limited sharing between animals. The host genetics were found to be related to the microbial composition in milk.
