为了界定断奶过程的不同阶段，并了解哺乳和生长之间的关系，哺乳性能和母婴相互作用与牛奶转移的演变密切监测一组林地驯鹿（Rangifer tarandus caribou）从出生到160天。哺乳率和总哺乳时间在前20天迅速下降，之后缓慢下降，而哺乳持续时间在前20天保持稳定，之后逐渐下降。在出生后的前20天，哺乳成功率从90%下降到50%，由母亲终止哺乳的比例从30%增加到90%，哺乳的比例从40%增加到几乎100%。在初生至20天的哺乳期内，母亲舔乳率为70%，20至40天为40%，随后不到20%。在出生后的前30天，舔乳的时间比不舔乳的时间长。哺乳是由小牛发起的，在更多的时间。
To delimit the different stages of the weaning process and to understand the relationship between suckling and growth, the evolution of suckling performance and mother–young interactions associated with milk transfer was closely monitored in a group of woodland caribou (Rangifer tarandus caribou) from birth up to 160 days. Suckling rate and total suckling time dropped rapidly during the first 20 days and slowly thereafter, while suckle duration remained stable during the first 20 days and decreased gradually thereafter. In the first 20 days of life, suckling success declined from 90 to 50%, the proportion of suckles terminated by the mother increased from 30 to 90%, and the proportion of suckles with bunting increased from 40 to almost 100%. The mother licked the calf in 70% of the suckles from birth to 20 days, 40% from 20 to 40 days, and less than 20% subsequently. Suckles with licking were longer than suckles without licking during the first 30 days of life. Suckling was initiated by the calf in more t...
