| 摘 要： | 对不同泌乳期莎能奶山羊初乳的一般理化性质和热稳定性进行了研究。结果表明,莎能奶山羊初乳的密度、酸度、折光度均高于常乳,而pH值低于常乳,随泌乳期的延长,初乳的各指标逐步接近常乳;分娩后48 h内莎能奶山羊初乳煮沸凝固,48 h后莎能奶山羊初乳煮沸不凝固;泌乳期越短的莎能奶山羊初乳的热稳定性越差。

| Abstract: | This paper studied the physicl-chemical properties and the thermostability of Saanen goat colostrum in different lactation periods.The results showed that the density,dipter and acidity were higher than those of common milk,but pH value was lower than that of mature milk,the contents of every indexes were more close to those of mature milk with the prolong of lactation;When boiled,Saanen goat colostrums coagulated before 48 h of lactation,but after 48 h of lactation,when boiled,Saanen goat colostrums didn't coagulated;The shorter the lactation period was,the poorer the thermostability was. |
