Determining the Physiological and Reproductive Responses of Domyati Ducks to Different Dietary Levels of Coconut Oil as a Source of Medium-Chain Fatty Acids during Laying Period

July 11, 2021 Agricultural Sciences 0

The goal of this study was to determine the optimal level of coconut oil (CO) supplementation in the diet to improve Domyati duck performance. A total of 300 Domyati ducks (240 females and 60 males) aged 25 weeks were randomly assigned to four experimental groups of three replicates, with each replicate containing 5 males and 20 females. During the experiment, the groups were given CO concentrations of 0 percent, 1.0 percent, 1.5 percent, and 2.0 percent. The results showed that egg weight, egg number, and egg mass increased significantly in the treated groups when compared to the control group. Furthermore, the fertility and hatchability percentages in the 1.0 and 1.5 percent CO groups were higher than in the other experimental groups. The level of low-density lipoprotein in ducks given CO was significantly lower than in the control group. It is concluded that including CO at a concentration of 1.5 percent could be sufficient and beneficial for improving the reproductive and physiological performance of Domyati ducks.
