Abstract

Abstract:

Enhancing the milk yield of dairy cows is crucial for strengthening the core competitiveness of our country's dairy industry and fostering innovation and development within the sector. The detection of mammary development across various stages in dairy cows is instrumental in preemptively identifying reserve cows with high lactation potential, promptly monitoring the mammary condition of both lactating and dry dairy cows, and providing a critical reference for the feeding and management practices tailored to different stages of dairy cows. Currently, conducting a comprehensive assessment of mammary development in dairy cows poses challenges due to cost and maneuverability factors. In this paper, we review the characteristics of mammary development of cows in different stages and summarizes both domestic and international methods for evaluating mammary development. It provides a detailed summary of sample collection and developmental evaluation indicators from invasive and non-invasive perspectives. The application advantages and development prospects of histological, molecular biological, and imaging techniques in assessing mammary development in dairy cows are highlighted. The content of this review aims to enrich mammary evaluation technologies of dairy cows in China, and provide technical guidance for improving the yield of dairy cows and perfecting the breeding system of high-yielding dairy cows.

Key words: dairy cow, mammary development, mammary biopsy, imageology technology
