A Review on Meat Quality Evaluation Methods Based on Non-Destructive Computer Vision and Artificial Intelligence Technologies.

Increasing meat demand in terms of both quality and quantity in conjunction with feeding a growing population has resulted in regulatory agencies imposing stringent guidelines on meat quality and safety. Objective and accurate rapid non-destructive detection methods and evaluation techniques based on artificial intelligence have become the research hotspot in recent years and have been widely applied in the meat industry. Therefore, this review surveyed the key technologies of non-destructive detection for meat quality, mainly including ultrasonic technology, machine (computer) vision technology, near-infrared spectroscopy technology, hyperspectral technology, Raman spectra technology, and electronic nose/tongue.

Understanding gaseous reduction in swine manure resulting from nanoparticle treatments under anaerobic storage conditions.

Manure is an impending source of carbon (C), sulfur (S) and water (HO). Consequently, microbial populations utilize these constituents to produce methane (CH), carbon dioxide (CO), greenhouse gases (GHGs), and hydrogen sulfide (HS). Application of nanoparticles (NPs) to stored manure is an emerging GHG mitigation technique.

Nanoparticles in mitigating gaseous emissions from liquid dairy manure stored under anaerobic condition.

A number of mitigation techniques exist to reduce the emissions of pollutant gases and greenhouse gases (GHGs) from anaerobic storage of livestock manure. Nanoparticle (NP) application is a promising mitigating treatment option for pollutant gases, but limited research is available on the mode of NP application and their effectiveness in gaseous emission reduction. In this study, zinc silica nanogel (ZnSNL), copper silica nanogel (CuSNL), and N-acetyl cysteine (NACL) coated zinc oxide quantum dot (Qdot) NPs were compared to a control lacking NPs.

In vitro evaluation of nano zinc oxide (nZnO) on mitigation of gaseous emissions.

Background: Enteric methane (CH) accounts for about 70% of total CH emissions from the ruminant animals. Researchers are exploring ways to mitigate enteric CH emissions from ruminants. Recently, nano zinc oxide (nZnO) has shown potential in reducing CH and hydrogen sulfide (HS) production from the liquid manure under anaerobic storage conditions.

Evaluation of microbial fuel cell (MFC) for bioelectricity generation and pollutants removal from sugar beet processing wastewater (SBPW).

Bioelectricity generation from biodegradable compounds using microbial fuel cells (MFCs) offers an opportunity for simultaneous wastewater treatment. This study evaluated the synergy of electricity generation by the MFC while reducing pollutants from sugar beet processing wastewater (SBPW). A simple dual-chamber MFC was constructed with inexpensive materials without using catalysts.

Characterization of zinc oxide nanoparticle (nZnO) alginate beads in reducing gaseous emission from swine manure.

Hydrogen sulfide (HS) and greenhouse gases' emission from livestock production facilities are of concern to human welfare and the environment. Application of nanoparticles (NPs) has emerged as a potential option for minimizing these gaseous emissions. Application of bare NPs, however, could have an adverse effect on plants, soil, human health, and the environment.

The effect of feeding high fat diet to beef cattle on manure composition and gaseous emission from a feedlot pen surface.

Background: Dietary manipulation is a common practice to mitigate gaseous emission from livestock production facilities, and the variation of fat level in the diet has shown great influence on ruminal volatile fatty acids (VFA) and enteric methane generation. The changes in dietary fat levels influence rumen chemistry that could modify manure nutrient composition along with odor and gaseous emissions from manure management facilities.

Methods: A field experiment was carried out on beef cattle feedlots to investigate the effect of four levels of dietary fat concentrations (3 to 5.

Greenhouse gas emissions from beef cattle pen surfaces in North Dakota.

There is a global interest to quantify and mitigate greenhouse gas (GHG) (e.g. methane-CH4, nitrous oxide-N2O and carbon dioxide-CO2) emissions in animal feeding operations.
