Comparatiove Analysis of Beef Quality of Linan and Lilu Cattle

The objective of the study is to analyze the beef product physicochemical properties and nutritional quality of Linan and Lilu cattle so as to provide scientific background for production practice and future breeding.The study has researched on the beef quality property of Limousin,Linan and Lilu cattle,determine the beef color,marbling,dehydrating rate,cooked beef percentage,tenderness,pH value,moisture,crude protein,crude fat,crude ash and other physicochemical properties as well as the amino acid content of beef product. The result showed that Lilu cattle has better commercial property than Linan cattle,it has fairly high content in protein,with low fat content,good taste and other targets are also optimal.Lilu cattle have better essential amino acid content,total amino acid content and better nutritional value than Linan cattle. The conclusion is that Lilu cattle has better beef quality than Linan cattle.
