Effects of Taurine Supplementation on Performance, Egg Quality, Blood Parameter and Liver Lipid and Lipid Peroxidation Levels of Laying Hens Fed High Fat Diet

Abstract

The current study was conducted to estimate the effect of dietary taurine on performance, egg quality, blood parameter, liver lipids and lipid peroxidation level of laying hens fed high fat diet. Two hundred eighty laying hens, forty five weeks of age, were allocated to four treatment groups with seven replicates of 10 each per treatment for 4 weeks. Experimental diets were assigned to each of the four groups: control diet (CON), CON with 0.5% taurine (CT), CON with 5% soybean oil (HF), and CON with 5% soybean oil and 0.5% taurine (HFT). Egg weight was significantly lower in the control than the CT (P<0.05). However, the HFT was similar to the level compared to both control and HF. Serum concentrations of total cholesterol, triglyceride and glutamic oxaloacetic transaminase (GOT) were significantly decreased by about 30%, 36% and 20%, respectively in the HFT compared to the HF (P<0.05). In the liver tissue, triglyceride concentration tended to be lower by about 28% in the HFT compared to the HF (P<0.05). The hepatic lipid peroxidation level was significantly decreased by about 25% in the HFT compared to the HF (P<0.05). These results indicated that taurine supplementation improved the serum total cholesterol, triglyceride concentration, and decreased hepatic lipid peroxidation level without affecting performance in laying hens fed high fat diet.(Key words : taurine, lipid metabolism, lipid peroxidation, high fat diet, laying hens) † To whom correspondence should be addressed : hschoe@jbnu.ac.kr 타우린(β-amino ethansulfonic acid)은 함황 아미노산의 일

Effect of taurine and bile acid supplementation and their interaction on performance, serum components, ileal viscosity and carcass characteristics of broiler chickens

“…Several earlier studies showed that taurine supplementation had clear effect on reducing serum and liver cholesterol, triglycerides and atherosclerotic lipid accumulation (Matsushima et al, 2003;Militante & Lombardini, 2004). These results are consistent with the findings of Shim (2010) who observed that Tau supplementation improved serum total cholesterol and triglyceride concentration of laying hens fed high fat diet. A recent study showed that 0.20% taurine supplementation increased the content of serum HDL, serum lipoprotein lipase and liver hepatic lipase activity (Zeng et al, 2011) abc Means with different superscripts within the same column are significantly different (P <0.05).…”
