A Comprehensive Evaluation System of Dietary Nutrient Balance and Characteristics of Nutrition and Physiology in Transition Dairy Cows
摘要
Abstract
The transition period is a pivotal period in the whole lactation cycle of dairy cows, which involves the fetal growth and development, health maintenance, renewal and reconstruction of the mammary gland, as well as the onset of lactation and so on. Hence, the precise management of transition cows is highly correlated with the health and lactation performance. As research continues, the main metabolic characteristics of transi-tion dairy cow become comparatively clear. However, the evaluation systems for dietary nutrient balance and body nutritional physiological condition are not completely established either. Moreover, a few individual bio-markers are usually detected to reflect the physiological status of transition dairy cows, and the representative-ness remains controversial. Till now, the comprehensive evaluation system is rarely applied in transition dairy cows. In this review, we summarized and discussed the comprehensive evaluation system of transition dairy cows, thereby providing scientific basis and technical references for further explicating nutrient balance and metabolic dynamics, as well as developing nutrient requirements and conducting precise feeding strategies.关键词
