The effect of various vegetable oils in diets on the percentage of internal organ weights in local male ducks

Abstract

Abstract This study aims to determine the effect of vegetable oils varieties in diets on the percentage of internal organ weights in 9 weeks old local male ducks. It was conducted using a completely randomized design (CRD) in a unidirectional pattern with 4 treatments and 6 replications, consisting of 6 ducks each. The treatments used include; P1: (96% basal ration + 4% palm oil); P2: (96% basal ration + 4% canola oil); P3: (96% basal ration + 4% coconut oil) and P4: (96% basal ration + 4% soybean oil). Furthermore, the data were analyzed using the one way analysis of variance (ANOVA) while the, Duncan’s multiple range test (DMRT) was used to examine significant differences among treatments. The results showed that the percentage of intestinal weights indicated significant results (P < 0.05), while the percentage of heart weights, gizzard weight, intestine length, and percentage of caecum weight were not significant (P > 0.05). Based on the results, the addition of vegetable oils up to level 4% in the ration affect the percentage of intestinal weight. However, it had no effect on the percentage of internal organ weight and intestinal length.
