在甲鱼饲料中添加油脂能够很好地提高饲料效率。添加豆油饲料效率可提高6.36%,添加玉米油可提高12.23%,添加花生油可提高11.54%,添加鱼油可提高17.28%。同时,在饲料中添加油脂能很好地促进甲鱼生长,获得极大的增重率。添加豆油增重率可提高15.81%,添加玉米油可提高28.13%,添加花生油可提高28.76%,添加鱼油可提高38.1%。添加油脂可表现明显的生长优势,添加豆油特定生长率可提高8.77%,添加玉米油可提高15.79%,添加花生油可提高16.67%,添加鱼油可提高21.05%。试验表明:在甲鱼饲料中添加油脂时,不论是动物油还是植物油,添加量必须大于1%时才对甲鱼的生长有明显作用,几种油脂的最佳添加量分别是豆油2%~5%,玉米油和花生油为1%~3%,鱼油为1%~5%。同时在甲鱼饲料中添加鱼油比添加植物油,如:豆油、玉米油和花生油的效果更好。
In the turtle feed fat can improve feed efficiency. Add soybean oil feed efficiency can be increased 6.36%, add corn oil can increase 12.23%, add peanut oil can increase 11.54%, add fish oil can increase 17.28%. At the same time, the addition of fat in feed can promote the growth of soft-shelled turtles and obtain a great rate of weight gain. Adding soybean oil weight gain rate can increase 15.81%, add corn oil can increase 28.13%, add peanut oil can increase 28.76%, add fish oil can increase 38.1%. Addition of fat can show obvious growth advantage. The specific growth rate of soybean oil can be increased by 8.77%, 15.79% by adding corn oil, 16.67% by adding peanut oil, and 21.05% by adding fish oil. The results showed that when the oil was added to the turtle feed, no matter it was animal oil or vegetable oil, the addition amount must be greater than 1%, which had a significant effect on the growth of soft-shelled turtles. The optimal additions of several oils were 2% -5% Corn oil and peanut oil is 1% ~ 3%, fish oil is 1% ~ 5%. At the same time, the addition of fish oil in turtle feed is better than adding vegetable oil, such as soybean oil, corn oil and peanut oil.
