Biocultural vulnerability of traditional crops in the Indian Trans-Himalaya

This study found that in the Indian Himalayas, traditional black pea and barley crops outperformed introduced green peas in survival, flowering, and stem height in a single-year field experiment. Genomic analysis indicated black peas are genetically distinct, suggesting a valuable genetic resource. Nutritional analysis confirmed their high protein and nutrient content.

Early pregnancy-induced transcripts in peripheral blood immune cells in Bos indicus heifers

This study identified several novel genes in peripheral blood immune cells (PBMCs and PMNs) of pregnant Bos indicus heifers that are differentially expressed compared to non-pregnant heifers as early as 18 days after insemination. These genes, including interferon-stimulated genes and others not previously associated with pregnancy, could potentially be used as early pregnancy biomarkers in cattle.

Dynamics of uterine microbiota in postpartum dairy cows with clinical or subclinical endometritis

Subclinical endometritis (SCE) cows had a similar uterine microbiome to healthy cows, but clinical endometritis (CE) cows showed distinct dysbiosis, characterized by increased Bacteroidetes and Fusobacteria, and Trueperella. This difference persisted across multiple time points postpartum (10, 21, and 35 days in milk), suggesting early establishment and persistence of dysbiosis in CE.

Red seaweed (Asparagopsis taxiformis) supplementation reduces enteric methane by over 80 percent in beef steers

Supplementing beef steer diets with Asparagopsis taxiformis seaweed reduced enteric methane production by up to 80%, with reductions persistent over the 21-week study period. The efficacy of the seaweed increased as the proportion of non-fiber carbohydrates in the diet increased. While DMI decreased in high seaweed groups, ADG was unaffected, leading to improved feed conversion efficiency. No bromoform residues were detected in the meat, but iodine levels increased with seaweed inclusion, albeit remaining far below toxicity limits for humans.

Impact of water deficit stress in maize: Phenology and yield components

This study investigated the impact of water deficit stress (WDS) on different maize lines. The researchers found that WDS negatively affected yield and other key traits in both drought-tolerant (DT) and non-drought tolerant (NDT) lines, although DT lines generally showed better performance under stress. They identified several traits, including number of leaves, stomatal density, and root characteristics, that may contribute to WDS tolerance in maize.
