The aim of this study was to investigate the effects of rare earth citrate on slaughter performance,meat quality and fat metabolism of Jinjiang cattle.A total of 12 heads of Jinjiang bulls with the similar age and average weight(374.75±4.02) kg were randomly divided into 2 groups:control group and test group.The addition level of rare earth citrate in diets was 0 mg/kg(Control group),400 mg/kg(Test group),respectively.The experimental period was 70 d.At the end of the feeding experiment,slaughtering performance was measured,and then the meat quality index,fat metabolism related enzyme and hormone index were analyzed.The results showed that:(1) The addition of rare earth citrate significantly increased the average daily gain(P0.05) and decreased the feed weight ratio(P0.05).(2)The addition of rare earth citrate could significantly increase the levels of GH and leptin in serum(P0.05).(3)The supplementation of rare earth citrate significantly decreased the abdominal fat rate and fat rate(P0.05),and had a tendency to decrease the back-fat thickness and the plate oil rate of jinjiang bull(0.05≤P≤0.1).(4)The addition of rare earth citrate significantly increased the content of crude protein in beef(P0.05),and decreased the contents of crude fat and dry matter(P0.05).At the same time,there was a tendency to increase the shear force(0.05≤P≤0.1).(5)The addition of rare earth citrate in the diet significantly reduced the activity of MDA(P0.05)and had the tendency to decreased the activity of FAS(0.05≤P≤0.1)in the liver.(6)The addition of rare earth citrate in the diet significantly increased the activity of LPL(P0.05),and had the tendency to increase the level of TL(0.05≤P≤0.1)in the liver.In conclusion,adding 400 mg/kg rare earth citrate to diet could improve the performance and slaughter performance of Jinjiang cattle,and increase the content of crude protein in muscle.At the same time,the effect of reducing the fat content of Jinjiang yellow cattle during fattening period was obvious,and improving the efficiency of beef cattle breeding.
