| 1 | Systematic analysis of feeding behaviors and their effects on feed efficiency in Pekin ducks显示文摘Background: Feeding behavior study is important for animal husbandry and production. However, few studies were conducted on the feeding behavior and their relationship with feeding efficiency in Pekin ducks. In order to investigate the feeding behavior and their relationship with feed efficiency and other economic traits in Pekin ducks, we selected 358 male Pekin ducks and recorded feeding information between 3 to 6 wk of age using automatic electronic feeders, and compared the feeding behavior under different residual feed intake(RFI) levels.Results: We observed that total feed time, daily feed intake and feed intake per meal had strong positive correlations with feed efficiency traits; moreover, strong correlation between feed intake per meal and body weight was found(R=0.32, 0.36). Daily feeding rate meal and meal duration had weak correlations with feed efficiency(R=0.14~0.15). The phenotypic correlation of between-meal pauses, with feed efficiency was not observed. When daily changes were analyzed, high RFI ducks had the highest feed consumption over all times, and obvious differences in daily visits were found among different RFI level animals during the middle period; these differences were magnified with age, but there was no difference in daily meal number. Moreover, our data indicate that high RFI birds mainly take their meals at the edge of the population enclosure, where they are more susceptible to environmental interference.Conclusions: Overal, this study suggests that the general feeding behaviors can be accurately measured using automatic electronic feeders and certain feeding behaviors in Pekin ducks are associated with improved feed efficiency. | Feng Zhu Yahui Gao Fangbin Lin Jinping Hao Fangxi Yang Zhuocheng Hou | 2018 | Journal of Animal Science and Biotechnology2018，9，1： | 1 |
| 2 | Kinetics and Products Distribution Study on the Catalytic Effect of Zn/HZSM-5 over Pyrolysis of Chlorella through TG-FTIR and Py-GC/MS显示文摘In this study,both the pyrolysis and catalytic pyrolysis behaviour of chlorella were investigated using thermogravimetric analysis combined with Fourier Transform Infrared spectrum(TG-FTIR)and Py-GC/MS.The results of TG indicated the pyrolysis of chlorella was divided into three stages,and the Coats-Redfern kinetic model was used for the analysis and validation of the obtained thermal data.The regression coefficients indicated that the pyrolysis of chlorella was close to second-order reaction.The activation energy of pyrolysis of chlorella and catalytic pyrolysis of chlorella+HZSM-5,chlorella+Zn/HZSM-5 was 61.645,59.080 and 56.808 kJ·mol^(−1),respectively.Combined with the data of FTIR,we found that the addition of the HZSM-5 effectively reduced the activation energy required by pyrolysis;the addition of the Zn/HZSM-5 could not only reduce the activation energy,but also reduce the yield of oxygen-containing compounds,increase the emissions of CO_(2),and facilitate the production of high value-added hydrocarbon products.These results were also verified by Py-GC/MS that the addition of Zn/HZSM-5 could reduce the formation of ketones and aldehydes and increase the production of nitrogen-containing compounds.Thus,through the catalytic pyrolysis of chlorella,the utilization range of chlorella can be expanded,and better bio-oil can be obtained,which will play a crucial role in the selection of available energy in the future. | WANG Lu YE Tao MA Xianming LIN Yan CHEN Juan WANG Fangbin MA Peiyong LIU Jian | 2023 | Journal of Thermal Science2023，32，4： | 0 |
