For example, when Tong Jianming and Na Ren Sa added 0.05% to the piglet diet, it was found that the daily gain of the experimental group was significantly higher than that of the control group, the average feed intake increased by 65,438+0,654,38+0.6%, and the feed conversion efficiency was also improved. The hair and skin of the experimental pigs are smooth, they like to eat and sleep well. The analysis of economic benefits shows that the extra profit per kilogram of diet with flavor is 0.278 yuan, and the benefits are very considerable. Zeng et al. conducted an experiment on the effect of feeding young soft-shelled turtle with ten spices, and the daily feeding amount was calculated according to 4% ~ 6% of body weight. The results showed that adding 0.2% and 0.3% spice to the compound feed, the food intake and daily gain of juvenile soft-shelled turtle gradually increased, and the feed utilization rate increased in turn. Considering the saving of material cost, it is most appropriate to add 0.2% Toxoplasma gondii essence (bait 1 1000 yuan/ton, Toxoplasma gondii essence1/0 yuan/ton, soft-shelled turtle calculated as 300 yuan/kg).
