Article Abstract

Some starch in distiller's grains has low utilization rate and serious waste of resources due to its combination with endogenous non-starch components (proteins). This study explored the impact of removing different endogenous proteins on starch molecules' physicochemical structure and brewing characteristics. Results revealed β-sheet-dominated proteins in fermented grains, with alkali-soluble proteins being most abundant (37.47 %). The removal of protein resulted in the formation of a porous structure on the surface of starch. The swelling degree, freeze-thaw stability and in vitro digestion characteristics of each sample were significantly improved except as solubility. Among them, alcohol-soluble protein had obvious promoting effect on pore formation and gelatinization, and both alcohol-soluble protein and alkali-soluble protein could weaken the interaction of starch complex and improve the brewing performance. This provides a new idea for improving the efficient utilization of starch and reducing the waste of resources in the future liquor brewing process.

Background: Stored-product insects (Sitophilus spp., Plodia interpunctella, Sitotroga cerealella) drive substantial postharvest losses and increasingly resist synthetic fumigants. Valeriana wallichii roots yield volatile oils rich in short-chain acids and sesquiterpenes.

Over 1200 heavy feedlot cattle presented with severe tongue lesions during a 7-month interval. Review of the literature and discussions with colleagues revealed previous similar outbreaks had occurred in Canada and the USA, with extensive investigations conducted and no cause identified. In the current outbreak, examination of the environment, feed, water, cattle behavior, and husbandry systems were conducted, as well as diagnostic testing including necropsy, histopathology, bacteriology, virology, and toxicology.

Livestock grazing endophyte-infected (E+) tall fescue can exhibit persistent systemic vasoconstriction and fescue toxicosis. Isoflavones in legumes, most notably red clover (RC), are known hypotensive agents. The objective of the experiment was to evaluate the effect of isoflavone supplementation via RC hay, every day or every other day (QOD), on average daily gain (ADG) of steers grazing E+ tall fescue pastures and their physiological recovery after grazing when managed on a non-toxic diet (28-d).

This study evaluated the effects of dietary probiotic-fermented corn wet distillers grains (FCWDGs) on finishing pigs. Three strains (CGMCC21218, CCTCC2022073, and CICC10275) were used to ferment corn wet distillers grains, yielding FCWDGs-1, FCWDGs-2, and FCWDGs-3. A total of 128 130-day-old Anqing six white pigs were randomly assigned to four groups: a control group and groups supplemented with 6% FCWDGs-1 (T1), FCWDGs-2 (T2), and FCWDGs-3 (T3).

Introduction: Rising global populations and climate change necessitate increased agricultural productivity. Most studies on rice panicle detection using imaging technologies rely on single-time-point analyses, failing to capture the dynamic changes in panicle coverage and their effects on yield. Therefore, this study presents a novel temporal framework for rice phenotyping and yield prediction by integrating high-resolution RGB imagery with deep learning-based semantic segmentation.
