| TThis report aimed to determine the effect of lipopolysaccharide (LPS) on food intake in broiler chicks with different rations. All birds received a starter diet until five days of age, but experimental diets were provided on days of injections. In experiment 1, chickens received an intracerebroventricular (ICV) injection of LPS (25, 50, and 100 ng) with a standard diet. In experiment 2, chickens received intraperitoneal (I.P.) injections of LPS (50, 100, and 200 µg) with a standard diet. In experiment 3, birds received ICV injection of saline and different diets: a standard diet without fat, a diet containing nutrient energy 20% higher than standard, a diet containing nutrient energy 20% lower than standard, and a standard diet containing fat were offered to them to investigate desire of chicken to diets. Experiments 4-6 were similar to experiment 3, except chickens received ICV injections of LPS. In experiments 7-9, chickens received I.P. injections of LPS with different diets. Then, cumulative food intake was measured until 180 minutes post-injection. According to the results, ICV injection of LPS decreased food intake (P<0.05). I.P. injection of the LPS reduced food intake (P<0.05). ICV injection of saline increased chickens' desire for the standard diet with fat (P<0.05). ICV injection of the LPS(50 and 100 ng) increased the appetite for a standard diet with nutrient energy 20% higher than standard and a standard diet containing fat at 120 and 180 min after injection(P<0.05). In addition, I.P. injection of LPS (200 µg) significantly increased the desire for a standard diet with nutrient energy 20% higher than standard and a standard diet containing fat (P<0.05). These results suggested chicken's desire for different types of rations affects by central or peripheral administration of the LPS. | ||
