Examining the impact of compound plant essential oils on the property,nutrient digestion,and economic benefits of dairy cow
The objective of this trial is to examine the effects of compound plant essential oils on the property,nutrient digestion,and economic benefits of dairy cows.24 Holstein lactating cows with alike production times,milk production,and lactation phases were selected and casually divided into an experimental group(n=12)and a control group(n=12).The feed of cows in the control group and treatment group were a full mixed diet.The experimental group added+60mg/KG of composite plant essential oil to the feed,while the control group did not add any plant essential oil.The mixed plant essential oil was consisting of cinnamaldehyde and clove oil.In terms of production performance,it was found that compared with the control group,the treatment group showed an increase in daily milk production of 13.97%(P＜0.05),and an enhancement in milk fat and milk protein level of 2.56%and 14.46%(P＜0.05),respectively.In terms of nutrient digestion,the ingestion of dry matter and crude protein in the treatment group was lower than that in the control group(P＜0.05).The decided digestibility of neutral detergent fiber and crude fat in the experimental group was higher than that in the control group(P＜0.05).The methane quantity in the rumen of cows in the control group was importantly higher than that in the observational group,with an addition of 31.88%(P＜0.05).Contrast with the control group,the experimental group showed an increase of 6.45%,13.10%,and 4.33%in volatile fatty acids,propionic acid,and acetic acid,respectively(P＜0.05).In terms of economic benefits,the treatment group had taller total milk yield,milk protein,and milk fat amount compared to the control group.The average economic benefit per cow in the experimental group increased by 21.12 yuan.
