Abstract:

Milk progesterone profiles in Chengdu Mah (CM) , Saanen ( S ) goats and their crosses (F1, CMXS were determined using radioim-munoassay ( RIA ) and competitive protein-binding assay(CPBA)during the period of 1 to 130 days after kidding. Mean value of the Colos-tru'm progesterone was about 2-4 ng (ranging from 0.55to 9.96 ng) per day during the first five days postpartum. Different patterns of the progesterone profile in these does were recorded. The animals ex-hibited progesterone rises from 1 to 5 times during the experiment pe-riod and the frequencies of the progesterone rise were higher thanthat of of the behavioural estrus observed. First progesterone rise occurred on days 26-67,19-52 and 39-122 after kidding in CM,S and F1 goats respectively. Analysis of the frequency distribution of the milk progesterone concentration indicated that about 87.2, 94.4 and 93.9% of the value measured were below 10 ng/ml in CM, S and F1 does respectively.

摘要:

应用放射免疫分析和竞争蛋白结合分析法测定了成都麻羊、莎能羊及其杂交一代母羊产后四月内的乳中孕酮浓度变化。供试动物在试验期间的孕酮浓度一般保持基础水平,约有87.2%(成都麻羊)、94.4%(莎能羊)和93.9%(杂交羊)的测值在10ng/ml以下。孕酮浓度升高发生1—5次,较行为发情次数为多。第一次孕酮浓度升高发生在产后26—67天(成都麻羊)、19—52天(莎能羊)和39—122天(杂交羊)期间。产后五天内初乳中的孕酮含量平均为每日2—4ng。
