全混合日粮中添加柑橘皮精油对泌乳期奶牛生产性能和蹄病发生率的影响
Effects of Adding Citrus Essential Oils to the Total Mixed Ration on Milk Production Performance and Incidence of Hoof Disease in Lactating Dairy Cows
摘要
Abstract
The present study was carried out to investigate the effects of adding citrus peel essential oil to the total mixed ration(TMR)on TMR temperature,dry matter intake,milk yield and incidence of hoof disease of lactating Holstein.Based on similar performance paired principle,64 healthy Holstein dairy cattles were divided into two groups including trial group[milk production(29.98 ± 8.55)kg/d,30 g/d citrus peel essential oil in TMR]and control group[milk production(29.25 ± 7.07)kg/d,no citrus peel essential oil in TMR].The results showed that the temperature increasing rates of the trial group diet were significantly lower(P＜ 0.05)than those of the control group detected at 17:00 in June,13:00 and 17:00 in July and August.The dry matter intake of trial group cattle was significantly higher than that of control group(P ＜0.05)in May,and very significantly higher than that of control group(P ＜ 0.01)in June,July and August.The milk yield of trial group cattle were very significantly higher than that of control group(P ＜ 0.01)in June,July,August and September.There was no significant difference between the trial group and control group for the incidence of hoof disease.In conclusion,an addition of 30 g/(head· d)citrus peel essential oil can reduce the temperature of TMR,and improve the palatability of TMR and the freshness of TMR,and increase dry matter intake and milk yield,especially for Holstein dairy catde during the summer periods in the north when temperatures are high.关键词
