摘要

通讯作者：Ali Agus动物科学学院，加贾马达大学，印度尼西亚电子邮件：aliagus@ugm.ac.id摘要：本研究旨在测定泌乳奶牛添加富含矿物质的混合精油的产奶量和饲料利用效率。48头身体状况评分为3.45±0.58、泌乳天数为187.08±21.53天的荷斯坦-弗里斯奶牛被随机分配到两种饮食处理中，为期46天。处理包括在总混合日粮（TMR）中不补充（CON）或补充（AGB）0.5%的Agromix Booster®。所有奶牛每天两次服用相同的TMR（唯一的区别是是否存在Agromix Booster®）。对奶牛的产奶量、成分和干物质摄入量进行了每日监测，并确定了饲料效率。与CON相比，饲喂AGB的奶牛产奶量增加（P0.05）。此外，添加AGB提高了固体非脂肪和总固体产量（P0.05），添加0.5%日粮的混合矿物富集精油（Agromix Booster®）可以提高产奶量，但不影响荷斯坦-弗里斯奶牛的乳成分含量和饲料效率。

Effect of Mixed Mineral-Enriched Essential Oils Supplementation on Milk Production and Feed Efficiency of Lactating Dairy Cows

Corresponding Author: Ali Agus Faculty of Animal Science, Universitas Gadjah Mada, Indonesia Email: aliagus@ugm.ac.id Abstract: This study aimed to determine milk production and efficiency of feed utilization of a mixed mineral-enriched essential oils supplementation of lactating dairy cows. Forty-eight Holstein-Friesian cows with a 3.45±0.58 body condition score and 187.08±21.53 days in milk were randomly allocated to two dietary treatments for 46 days. Treatments consisted of no supplementation (CON) or supplementation (AGB) of 0.5% of Agromix Booster® in the Total Mix Ration (TMR). All cows were given the same TMR twice a day (the only difference was the presence or absence of Agromix Booster®). Daily monitoring of milk production, composition, and dry matter intake of cows was calculated and feed efficiency was determined. Compared with CON, cows fed AGB showed an increase in milk yield (P<0.05). However, no significant effects were detected on milk fat content and yield, protein content and yield, lactose content and yield, solid non-fat content, and total solids content (P>0.05). Furthermore, AGB supplementation increased solids non-fat and total solids yield (P<0.05). Dry matter intake and feed efficiency were not affected for dairy cows receiving AGB supplementation (P>0.05). The supplementation of mixed mineralenriched essential oils (Agromix Booster®) at 0.5% of feed ration could improve milk yield but did not affect milk component content and feed efficiency of Holstein-Friesian dairy cows.

期刊介绍： American Journal of Animal and Veterinary Sciences, a quarterly, peer reviewed publication and is dedicated for publication of research articles in the field of biology of animals and with the scientific understanding of how animals work: from the physiology and biochemistry of tissues and major organ systems down to the structure and function of bio molecules and cells; particular emphasis would given to the studies of growth, reproduction, nutrition and lactation of farm and companion animals and how these processes may be optimized to improve animal re- productivity, health and welfare. Articles in support areas, such as genetics, soils, agricultural economics and marketing, legal aspects and the environment also are encouraged. AJAVS is an important source of researcher to study articles on protection of animal production practices, herd health and monitoring the spread of disease and prevention in both domestic and wild animals.
