    Antimicrobial usage is particularly high in poultry production. Honey as a water supplement to poultry has been explored as a natural and safe antibiotic alternative. This study aimed to investigate the effects of different levels of honey as a water supplement on broilers' growth performance and chemical properties. Five dietary treatments were used: no supplement (T1), commercial electrolytes (T2), 5mL honey (T3), (7.5mL honey (T4), and 10mL honey (T5) per liter of water. The experiment used 150 1-day-old Cobb-400 broiler chicks, assigned to five treatments with three replications of ten (10) birds each (N=30) employing the Complete Block Design (RCBD) in three blocks. Results indicated that 5mL/L-10mL/L honey supplementation led to a significant (p < 0.05) decrease of 4.3% to 7% in feed consumption compared to those with electrolytes. Similarly, using 5mL/L of honey showed 12.5% lower FCR compared with T2 and 24.3% compared with T1. However, a higher level of honey was comparable to T2, indicating that honey supplementation improved feed utilization and reduced feed cost at a certain level. Results of the proximate analysis, particularly on moisture content (MC), crude protein (CP), crude fat (CF), and total carbohydrates ((TC), revealed numerical differences. Samples with 5mL/L to 7.5mL/L levels of honey showed a higher MC, CP, and TC content and lower CF than T2. This implies that honey as a drinking water supplement offers practical advantages in feed consumption and efficiency and in improving the chemical and nutritional properties of chicken meat. A choice for healthier production.

    Taxonomic evidences supporting the establishment of ‘sibujing', a traditional condiment crop from the Philippines, as Allium chinense G.Don
    (Nordic Journal of Botany, 2023-10-06) Vera Cruz, Juan Rodrigo A.; Gentallan, Renerio P.; Bartolome, Michael Cedric B.; Calimpang, Ison A.; Quiñones, Kristine Joyce O.; Manting, Muhmin Michael E; Madayag, Roselle E.; Lalusin, Antonio G.; Hernandez, Jose E.; Manuel, Ma Carmina C; Endonela, Leah E.; Borromeo, Teresita H.
    'Sibujing' is an emerging crop species in the Philippines with recorded traditional use as condiment in localized areas in Mindanao. However, its taxonomic identity is confused as it has been attributed to various taxa of Allium. We characterized the morphological, phytochemical and molecular characteristics of a ‘sibujing' accession to establish the taxonomic belonging and correct species name of the crop and elucidate its baseline characteristics for its continued utilization. Through next‐generation sequencing, we assembled the quadripartite genome of a ‘sibujing' accession from Zamboanga del Norte. The generated chloroplast genome revealed 100% similarity to the earlier established 152 525‐bp‐long A. chinense G.Don. plastome from China. Morphological characteristics also support this identification as both bears leaves with hollow 3–5‐angled cross‐sections, scapes that are terete and solid, and distinctly toothed filament base. Saponins were also detected from its methanolic extract. Phylogenetic reconstruction based on the sequenced ITS region, a nuclear barcode, suggested that the species was closest to taxa belonging to Allium sect. Sacculiferum subg. Cepa, further supporting its potential identity with A. chinense. Using a separate accession from a different locality in the Philippines, these findings were validated as the chloroplast genome assembled, phytochemical and morphological characteristics recorded were similarly established as close to A. chinense. This is the first definitive record of an Allium species from sect. Sacculiferum in the Philippines.
