The present investigation was conducted inside a canine unit at the BGB headquarters in Peelkhana, Dhaka. The primary objective of this study was to assess the impact of food enriched with soybean oil at varying dosages on the control of lipid profiles in dogs. A total of nine German Shepherd dogs, chosen without regard to their breed or gender, were included in the study due to their overall good condition. The weights of the dogs varied from 25 to 30 kg, while their ages spanned from 2 to 3 years. The canines were assigned randomly to three distinct groups, each consisting of three individuals. Group T0 was designated as the control group and was not administered any soybean oil in their diet. T1 and T2 groups were assigned to a diet supplemented with soybean oil. Group T1 had a daily supplementation of 5 ml, while group T2 received a higher supplementation of 10 ml oil per day. The duration of the trial spanned 28 days. The weights of the dogs involved in the experiment were documented, the shininess of their body coats was evaluated, and blood samples were obtained on days 0, 14, and 28 to analyze their lipid profiles. The findings indicated that the animals subjected to treatment had a statistically negligible (p>0.05) elevation in body weight while demonstrating a statistically significant enhancement in the shininess of their body coat when compared to the control group. The levels of serum cholesterol, triglycerides (TG), and low-density lipoprotein (LDL) exhibited a statistically significant reduction (p˂0.01) in both the T1 and T2 groups. Nevertheless, the treatment group exhibited a noteworthy (p˂0.01) elevation in the blood serum levels of high-density lipoprotein (HDL) in comparison to the control group. The study demonstrates that including food enriched with soybean oil yields a reduction in blood cholesterol, triglycerides, and LDL levels, while simultaneously improving HDL levels. Additionally, the study exposes the quality of the dogs’ body coats.
