Agro-industrial by-products as ruminant feed: Nutritive value and in vitro rumen fermentation evaluation.

In recent years, agricultural by-products have generated increasing interest as ruminant feed. In a completely randomized design with five experimental treatments, this in vitro study investigated the nutritional value of citrus pulp and onion peel as alternative feed for ruminants and their effects on rumen fermentation, digestibility, and gas production. The first group was the control (50% grass hay/50% concentrate mixture).

Effects of concentrate levels on intestinal fermentation and the microbial profile in Japanese draft horses.

In racehorses, feeding a high-concentrate diet could cause abnormal fermentation in the hindgut. This feeding management regime is not suitable for the nutritional physiology of horses. However, studies on the hindgut environment have yet to be reported in Japanese draft horses, so feeding management needs to be investigated in these horses.

Micro- and Macro-Algae Combination as a Novel Alternative Ruminant Feed with Methane-Mitigation Potential.

This study was conducted to provide alternative high-quality feed and to reduce methane production using a mixture of the minimum effective levels of , EG, and , AT. This study was performed as a 24 h in vitro batch culture. Chemical analysis demonstrated that EG is a highly nutritive material with 26.

Measurement of particulate matter 2.5 in surgical smoke and its health hazards.

Purpose: Surgical smoke is generated during the cauterization, coagulation, and incision of biological tissues by electrocautery, ultrasonic coagulation, incising devices, and lasers. Surgical smoke comprises water, water vapor, steam, and some particulate matter, including bacteria, viruses, cell fragments, and volatile organic compounds, which can pose health risks to the operating room personnel. In this study, we measured the concentration of particulate matter 2.

Insects as Novel Ruminant Feed and a Potential Mitigation Strategy for Methane Emissions.

This study is the first to evaluate the chemical composition and impacts of four different edible insects, (A.d), (B.p), (G.

The Efficacy of Plant-Based Bioactives Supplementation to Different Proportion of Concentrate Diets on Methane Production and Rumen Fermentation Characteristics In Vitro.

This In Vitro study was conducted to investigate the impact of plant-bioactives extract (PE), a combination of garlic powder and bitter orange extract, on methane production, rumen fermentation, and digestibility in different feeding models. The dietary treatments were 1000 g grass/kg ration + 0 g concentrate/kg ration (100:0), 80:20, 60:40, 40:60, and 20:80. The PE was supplemented at 200 g/kg of the feed.

Impacts of Mootral on Methane Production, Rumen Fermentation, and Microbial Community in an Study.

Methane mitigation strategies have a two-sided benefit for both environment and efficient livestock production. This preliminary short-term trial using Mootral (garlic and citrus extracts), a novel natural feed supplement, was conducted to evaluate its efficacy on rumen fermentation characteristics, methane production, and the bacterial and archaeal community. The experiment was performed as a batch culture using rumen fluid collected from sheep, and Mootral was supplemented in three concentrations: 0% (Control), 10%, and 20% of the substrate (50% Grass:50% Concentrate).

Effect of substituting soybean meal with euglena (Euglena gracilis) on methane emission and nitrogen efficiency in sheep.

This study evaluated methane (CH ) emission, intake, digestibility, and nitrogen efficiency in sheep fed diets containing replacement levels (0%, 33%, 50%, and 67% of soybean meal with euglena). In this experiment, four Corriedale wether sheep with an initial body weight of 53.8 ± 4.

Potential of anaerobic digestate of dairy manure in suppressing soil-borne plant disease.

Frequent use of pesticides to control soil-borne plant disease leads to environmental pollution and the development of pesticide resistance in phytopathogens. Soil amendment is considered to have the potential of suppressing plant disease because of its biological properties. However, information on anaerobic digestate is limited.

Prediction of enteric methane emission from beef cattle in Southeast Asia.

We conducted a meta-data analysis to develop prediction equations to estimate enteric methane (CH ) emission from beef cattle in Southeast Asia. The dataset was obtained from 25 studies, which included 332 individual observations on nutrient intakes, digestibilities, and CH emissions. Cattle were provided tropical forage or rice straw, with or without concentrates in individual pens equipped with indirect open-circuit head hood apparatus.

Valorizing waste iron powder in biogas production: Hydrogen sulfide control and process performances.

Biogas is composed of different gases including hydrogen sulfide (HS), which is a hazardous gas that damages pipes and generators in anaerobic digestion system. The objective of this study was to control HS by waste iron powder produced by laser cutting machine in a steel and iron industry. Waste iron powder was mixed with dairy manure at a concentration between 2.

Effect of temperature on survival of pathogenic bacteria in biogas plants.

The paper deals with the hygienic advantages of sanitation to treat dairy manure in full-scale biogas plants. The slurry samples were collected from two thermophilic biogas plants (55°C) and two mesophilic biogas plants (38°C) in Hokkaido Japan. A detectable number of Coli-aerogenes group and Enterococcus in the slurries after anaerobic digestion (AD) could not be found in either thermophilic biogas plants.

Collateral uterine blood flow in Holstein cows during the third trimester of pregnancy.

Blood flow to the gravid and nongravid uterine horns of four multiparous Holstein cows (mean +/- SD, BW=641.8 +/- 95.4 kg; age=4.
