Effect of feeding goat meat containing low cholesterol and rich omega-6 fatty acid on blood lipid status of white rat (Rattus norvegicus)

Abstract

Background and Aim: Healthy goat meat is an essential aspect in increasing consumer acceptance for this livestock product. The research aimed to examine the effect of goat meat containing low cholesterol and rich omega-6 fatty acid on the performance and blood lipid status of white rats (Rattus norvegicus). Materials and Methods: Thirty 2-month-old male white rats (R. norvegicus) weighing 195-230 g were randomly divided into three groups, with each group consisting of 10 rats. Group I was treated with a control feed (T0; BR I concentrate). Group II (T1) was treated with a mixed feed containing 50% control feed and 50% goat meat. Group III (T2) was treated with a mixed feed comprising 50% control feed and 50% goat meat with low cholesterol and rich omega-6 fatty acids. Each treatment was given ad libitum for 30 days. The variables measured were dry matter and organic matter consumption, daily body weight gain, feed conversion, triglyceride levels, total cholesterol, high-density lipoprotein (HDL) and low-density lipoprotein (LDL) cholesterol, and atherogenic index (AI). The data were analyzed statistically using analysis of variance in a completely randomized design. Results: The total, HDL, and LDL cholesterol levels at T0, T1, and T2 were as follows: 99.97, 35.97, and 50.43 mg/dL (total cholesterol); 108.35, 33.92, and 58.17 mg/dL (HDL cholesterol); and 101.43, 38.09, and 48.65 mg/dL (LDL cholesterol). The highest HDL and the lowest LDL cholesterol levels (p<0.05) were observed in the T2 treatment group, which had the lowest AI (1.69 vs. 1.77 and 2.19). Conclusion: The consumption of goat with low cholesterol and rich omega-6 fatty acids reduces the total cholesterol and LDL cholesterol, raises the HDL cholesterol levels, and decreases the AI.
