This study was conducted with the objective to determine carcass traits, meat yield, and primal meat cuts of Arsi, Harar, Jersey*Horro crossbred, and Ogaden cattle breeds at Haramaya University, Ethiopia. A total of 12 bulls of four cattle breeds (3 Arsi, 3 Harar, 3 F1 Jersey*Horro crossbred and 3 Ogaden) with almost similar ages were randomly assigned to four treatments in a completely randomised design (CRD). Data on carcass traits, meat yield, and primal meat cuts were analyzed using the General Linear Model (GLM) of the Statistical Analysis Software (SAS) 9.4 version. The overall averages of live body weight, hot carcass weight, chilled carcass weight, dressing percentages based on hot carcass weight, and rib eye area of experimental cattle breeds were 215.58 kg, 102.93 kg, 99.56 kg, 47.61%, and 8.13 inch2, respectively. The hot carcass weight and chilled carcass weight of the Ogaden (136.57;133.30 kg, resp.) breed were higher (p 2) ranging from 52.26% to 93.58%, primal meat cuts significantly (p dicted meat yield. In conclusion, the breed of cattle had a significant (p 0.05) influence on live body weight, hot and chilled carcass weight, dressing percentage, rib eye area, subcutaneous fat thickness, meat yield, and the weights of most primal meat cuts. The Ogaden cattle breed had a higher and better meat yield, carcass traits, and most primal meat cuts compared to other experimental cattle breeds. Furthermore, the inclusion of corn silage in the diet of fattening bulls improved the carcass and meat yield. Therefore, the

Carbon Monoxide Emissions from corn silage

Carbon monoxide (CO) emissions from corn silage were observed using Fourier Transform Infrared (FTIR) spectroscopy and laser spectroscopy. In the first experiment, corn silage was produced using laboratory bucket silos. Air samples were collected from the bucket silos during the first week of ensiling and analyzed using a low-resolution Bruker FTIR spectrometer coupled with a long optical path length White Cell. The CO concentration in the bucket silo gas, derived from the FTIR spectra using the LINEFIT program, was as high as 48.0 ppm. In the second experiment, air samples were collected through a flux chamber from an Ag-Bag silage pile on a commercial dairy that was opened several months after ensiling. The Ag-Bag air samples were analyzed using a high-resolution Bruker FTIR spectrometer, and CO concentrations were retrieved to be 6.83 ppm, corresponding to an area emission rate of 33.7 mg/(hour ·m2). An LGR N2O/CO gas analyzer based on infrared laser spectroscopy was also used to measure the CO concentrations from the same flux chamber. Elevated CO concentrations were observed from these silage sources. The present study revealed that CO was emitted by corn silage during different phases of ensiling. Annual CO emissions from the corn silage were estimated to be much lower than those from the well-known emission categories in San Joaquin Valley (SJV) and California, but comparable to those from food and agricultural sources in the SJV. It is also confirmed that FTIR spectroscopy is a viable method for measuring CO concentrations in complex gas mixtures, such as silage gas.

Review of Factors Affecting the Yield and Quality of corn silage

corn silage is the most popular and important source of energy and fber for ruminants. Much research focused on the chopping length, additives, sealing system, harmful bacteria and their toxins, and so forth, has been done on corn silage both at home in China and abroad. Some suggestions were presented in this review：（1） corn silage modulation： Whole-plant corn harvested at the milk-ripe stage with a dry matter （DM） content of 30%~40% was selected as silage material and treated by rubbing and cutting. In the process of silage, commercial Lactobacillus buchneri was inoculated, exogenous protease added appropriately, cellulose enzyme added depending on the phenological period, the silage container and the species of the animals, and coextruded polyethylene？polyamide oxygen barrier flm （OB） selected as the seal material. （2） Strengthening management： Aerobic exposure should be avoided at the storage stage and reduced during the feeding phase. The proportion of corn silage was increased depending on the type of animal and their management. （3） Suggestions for further research： Further studies would be needed for the effects of liquid and solid wastes on soil, water and vegetation, and the treatment of these wastes.

[Objective] To analyze the effects of major agronomic traits on yield in maize inbred lines. [Method] Incomplete diallel cross between three single-cross hybrids and 19 parent materials of com silage were performed, and the agronomic traits of the obtained 57 cross combinations were identified. [ Result] The regression equations between biomass and four important indicators （grain yield, rows per ear, plant height and straw yield） affecting biomass of com silage were established. The broad heritability of straw yield, plant height, rows par ear and ear length was higher than 50%. Genetic effects had a greater impact, while environmental factors had a smaller impact. Thus, it had great potential to improve these traits by genetic breeding. In addition, the broad heritability of biomass and grain yield was lower than 50%. [ Conclusion] Biorness and grain yield have greater interaction effects on environment, and the environmental impact should be considered for selection.

Detecting Nitrous Oxide in Complex Mixtures Using FTIR Spectroscopy: silage Gas

引用

Journal of Environmental Protection 2016年第12期7卷 1719-1729页

Nitrous oxide (N2O) is a greenhouse gas with about 300 times the global warming potential (GWP) of carbon dioxide (CO2). It is emitted from a wide range of sources and is responsible for about 6% of anthropogenic US greenhouse gas emissions. Analytical techniques are needed that can measure concentrations of N2O rapidly and inexpensively in sources that are also emitting other compounds that may interfere with the analytical process. In this work, we demonstrate the use of Fourier Transform Infrared (FTIR) spectroscopy to analyze N2O in the complex mixture of gases produced during the early phase of the silage making process. silage gas samples were collected into Tedlar bags from the bucket silos during the first week of corn ensiling. A bag of the silage gas was analyzed using a Bruker FTIR spectrometer coupled with a long optical path length White Cell. First, N2O infrared absorption bands were identified in the FTIR spectra of the silage gas by comparing them to both standard N2O gas and simulated infrared spectra which confirmed that N2O was present in the silage gas. Then, N2O concentration in the silage gas was derived from the FTIR spectra using LINEFIT program. It was demonstrated that FTIR spectroscopy is a viable method for measuring N2O concentrations in the silage gas.
