First Evidence of the Effects of Polyethylene Terephthalate Microplastics on Ruminal Degradability and Gastro-Intestinal Digestibility of Mixed Hay

Animals
Microplastics (MPs) raise environmental concerns. However, their effects on the ruminal–gastro-intestinal system have not yet been studied. This study aims to investigate the effects of polyethylene terephthalate (PET) MPs on the ability of the ruminal ...

Ruminal Degradability of Tropical Feeds and Their Potential Use in Ruminant Diets

Asian-Australasian Journal of Animal Sciences, 2003
كان الهدف من هذه الدراسة هو تحديد قابلية تحلل رقائق الكسافا (CC)، ونفايات الكسافا (CW)، والبطاطا الحلوة الصفراء (YP)، والبطاطا الحلوة البيضاء (WP)، والبطاطا الحلوة الأرجوانية (PP)، ووجبة الذرة (CM)، ونخالة الأرز (RB) باستخدام تقنية الموقع. تم استخدام توجيهين مجترعين بمتوسط وزن 303±10 كجم لتحديد قابلية تحلل DM و OM في الموقع.

Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals

Journal of Applied Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...

Effects of Glyphosate and Glyphosate‐Based Herbicides on the Mammalian Gut Microbiome: A Critical Review

Journal of Applied Toxicology, EarlyView.
ABSTRACT Glyphosate has long been considered to pose negligible direct risk to mammals on the grounds that its molecular target, 5‐enolpyruvylshikimate‐3‐phosphate synthase (EPSPS), of the shikimate pathway, is absent from animal cells. This rationale is inaccurate as a complete toxicological argument, because the shikimate pathway is present in some ...

Ruminal fermentation and methane emissions of corn silage harvested at the R4 and R5 phenological stages

Tropical and Subtropical Agroecosystems
Background: Corn silage is widely used in ruminant feeding; however, the ruminal utilization depends on the physiological stage at which the ensiling process is carried out.

Use of natural ensiling additives with tropical grasses: Physicochemical properties, in vitro fermentation characteristics, and microbial community diversity indices

JSFA reports, EarlyView.
Abstract Background Improving feed quality, availability, and cost‐effectiveness is a big challenge for livestock to ensure animal‐derived food for nutritional security. The aim of the study was to find out how some natural ensiling additives affect physicochemical properties, proximate composition, microbial population, in vitro fermentation ...

Intake, Digestibility, and Ruminal Degradability of Shredded Hay

Journal of Dairy Science, 1994
Thirty-two Outaouais intact male lambs averaging 39.1 kg were assigned randomly to a 2 x 2 factorial arrangement of treatments consisting of two forages and two methods of harvesting to determine intake and digestibility. The four treatments fed during the experiment consisted of alfalfa and timothy hays harvested with either a prototype mat maker or a

Ruminal and post-ruminal phytate degradation of diets containing rapeseed meal or soybean meal

Archives of Animal Nutrition, 2022
This study aimed to investigate ruminal and post-ruminal degradation of phytic acid (InsP6) in diets containing either rapeseed meal (RSM) or soybean meal (SBM). In Experiment 1, the effective degradability of crude protein (CPED) and InsP6 (InsP6ED) was evaluated by incubating RSM and SBM in situ in three rumen-fistulated lactating Jersey cows for 2 ...
