Lipids in liver wet and dry matter, liver moist and dry matter and their relationships were investigated based on species, sex and age in cows, buffaloes, sheep and goats. Mean percentage of lipids in liver wet and dry matter and liver dry matter in cows were 3.60%, 1.10%, 29.70%, and for buffaloes were 5.30%, 1.55%, 29.20%, sheep 3.00%, 0.83%, 27.90%, and goats 2.910%, 1.55% and 28.40%, respectively. The highest and lowest percentage of lipids in liver wet and dry matter was observed in buffaloes and sheep, and for the liver dry matter was recorded in cows and sheep, respectively. Analyses showed significant differences in liver parameters among ruminants (p < 0.01). Gender, except for goats, did not affect the animals' liver parameters. In overall 15.00% of buffaloes and 3.50% of cows showed over 10.00% lipids in liver, while none of small ruminants appeared to have over 6.00% lipids in liver. There was no correlation between liver lipid and liver dry matter. In conclusion mean percentage of lipid in liver dry matter in small ruminants was less than large ruminants. Liver dry matter was high in cows and low in sheep. Mean differences in liver parameters was significant, while the age and sex of the animals were not. Liver lipidosis in buffaloes seems greater than in cows, and in small ruminants it was negligible. No correlation was expected between liver parameters. Finally, on the basis of liver dry matter, the liver in ruminants ranked from cows to buffaloes, goats and sheep.
基于奶牛、水牛、绵羊和山羊的品种、性别和年龄，对肝脏湿物质和干物质中的脂质、肝脏湿物质和干物质及其相互关系进行了研究。奶牛肝脏湿物质和干物质以及肝脏干物质中脂质的平均百分比分别为3.60%、1.10%、29.70%，水牛分别为5.30%、1.55%、29.20%，绵羊分别为3.00%、0.83%、27.90%，山羊分别为2.910%、1.55%和28.40%。肝脏湿物质和干物质中脂质百分比最高和最低的分别是水牛和绵羊，而肝脏干物质中脂质百分比最高和最低的分别是奶牛和绵羊。分析表明反刍动物的肝脏参数存在显著差异（p < 0.01）。除山羊外，性别对动物的肝脏参数没有影响。总体而言，15.00%的水牛和3.50%的奶牛肝脏中的脂质含量超过10.00%，而小型反刍动物肝脏中脂质含量均未超过6.00%。肝脏脂质与肝脏干物质之间没有相关性。总之，小型反刍动物肝脏干物质中脂质的平均百分比低于大型反刍动物。奶牛的肝脏干物质含量高，绵羊的含量低。肝脏参数的平均差异显著，而动物的年龄和性别差异不显著。水牛的肝脏脂肪变性似乎比奶牛更严重，而在小型反刍动物中则可忽略不计。肝脏参数之间没有预期的相关性。最后，基于肝脏干物质，反刍动物肝脏的排名顺序为奶牛、水牛、山羊和绵羊。
