羔羊是指出生后到断奶前的小羊。20 日龄前,羔羊生理机能发育不完善,体温调节机能差,体内缺乏必要的免疫抗体,对外界环境的适应能力差,容易染病;21 日龄后,羔羊初步开始采食粗饲料并出现反刍活动。根据羔羊生理特点,加强羔羊培育,保证羔羊全活全壮,是羔羊培育的根本目标,也是提高成年奶山羊羊奶产量的重要举措。
Lambs are lambs from birth to weaning.Before the age of 20 days,the lambs'physiological function development is not perfect,the thermoregulation function is weak,the body lacks the necessary immune antibody,the adaptability to the external environment is poor,and they are easy to get sick.After the age of 21 days,they begin to eat roughage and ruminate.Strengthening the scientific cultivation of lambs is not only the requirement to improve the survival rate of lambs and ensure the lambs live and strong,but also an important measure to improve the milk yield and quality of adult dairy goats.
