新疆荷斯坦干奶牛与泌乳牛四季CO2 24 h排放量变化的研究
Carbon Dioxide Emission and Its Change of Xinjiang Hostein Dry Cows and Lactating Cows during the Four Seasons
摘要
Abstract
[Objective] This project aims to measure and analyze the changing trend of carbon dioxide concentration and emission quantity of dry and dairy cows in closed cowsheds in the hope of providing theoretical basis for energy saving and emission reduction in our country and regulation of greenhouse gas of ruminant animals.[Method]The experiment was begun from July,2011 to July 2012 on 20 dry cows and 20 lactating cows in the same cowshed to measure the emission of carbon dioxide in the four seasons.The egesta of each cow were measured in 24 hours at the beginning,in the middle and at the end of each quarter.[Result] The CO2 emission quantities of dry cows in the four seasons were 293.06,308.97,283.21 and 270.93 kg,respectively.The CO2 emission quantities of lactating cows were 330.45,335.63,322.22 and 308.33 kg,respectively.The CO2 emission quantity of dry cows for the whole year was about 1,135.5 kg.Lactating cows' yearly CO2 emission amount reached about 1,314.4 kg.[Conclusion] Four Seasons'temperature change had a certain influence on cows' CO2 emission,which was positively correlated with cow feed amount.关键词
