The effects of different levels of oregano oil in the basic diet on the growth performance,meat quality,and economic benefits of beef cattle
To analyze the effects of different levels of oregano oil in the basic diet on the growth performance,meat quality,and economic benefits of beef cattle.120 healthy beef cattle at 10 months old with similar weight(341.25±3.74kg)were selected for the experiment and randomly divided into 4 groups,with 3 replicates in each group and 10 cows in each replicate.The control group was fed a basic diet according to the Beef Cattle Feeding Standards(NY/T815-2004),while the other three groups were fed a basic diet+100 g/t,200 g/t,and 300 g/t of oregano oil,respectively.The experiment lasted for 60 days,during which all beef cattle were free to feed and drink.The results showed that:(1)In terms of growth performance,compared with the control group,the experimental group showed an increase in dry matter intake and average daily weight gain,with a significant increase of 14.32%(P＜0.05)and 13.71%(P＜0.05)in the 200 g/t oil group;The 300 g/t beef oil group significantly increased by 11.44%(P＜0.05)and 11.29%(P＜0.05).(2)In terms of meat quality,compared with the control group,the 100,200 and 300 g/t beef jerky oil group showed significant reductions in water loss,cooking loss,and shear force(P＜0.05),and the 100 g/t beef jerky oil group and 200 g/t beef jerky oil group had significantly higher water loss rates than the 300 g/t beef jerky oil group(P＜0.05).(3)In terms of economic benefits,compared with the control group,the feed costs of the 100,200 and 300 g/t beef oil group were significantly increased(P＜0.05),and the feed costs of the 100 g/t beef oil group were significantly lower than those of the 200 and 300 g/t beef oil group(P＜0.05).Compared with the control group,the 200 and 300 g/t beef oil group significantly increased feed consumption,beef cattle weight gain,weight gain benefits,and gross profit(P＜0.05).The gross profit of the 200 g/t beef to oil group is the highest,reaching 648.13 yuan/head.In summary,in beef cattle farming,oregano oil has the effect of improving growth performance,meat quality,and economic benefits.Among them,when the addition level of oregano oil is 200 g/t,the growth performance and economic benefits of beef cattle are the best.
