Effect of Concentrate Feed Replacement with Yeast Fermented Cassava Peels on Productive Performances of Yi-Liang Duck
Main Article Content
Abstract
A by product of cassava starch factories are cassava peels. It might be utilized as an ingredient in animal feed. Thus, the purpose of this research was to determine how adding yeast-fermented cassava peels to meals affected Yiliang duck productivity. A completely randomized experimental design was used mixed-gender Yi Liang ducks that were 14 days old and divided into 4 groups with 4 repeats each, a total of 96 ducks. They were raised in an open-system enclosure, with experimental pens measuring 1x2 meters, raised on a floor covered with wire mesh.The treatment consisted of commercial feed mixed with yeast-fermented cassava peel at levels of 0, 10, 20, and 30 percent. The ducks received ad libitum food and water. The experiment lasted for 60 days. The experimental results showed that ducks fed diets containing 0% and 10% yeast-fermented cassava peel had higher final body weight, weight gain, growth rate, and feed conversion ratio compared to those fed diets containing 20% and 30% yeast-fermented cassava peel, with statistically significantly differences (P<0.01). Additionally, ducks receiving 10% yeast-fermented cassava peel in their diet had the lowest feed cost per unit of weight gain, with statistically significantly differences (P<0.01). In conclusion, our experiment revealed that 10 % of the diet for raising Yi Liang ducks might consist of fermented cassava peels. produces Yiliang ducks with the highest production efficiency and the lowest feeding cost per unit of weight growth.
