Title: PATTERNS OF PLASMA PROGESTERONE, ESTROGENS AND ESTROGENIPROGESTERONE RATIO FROM BIRTH TO SIX MONTH OF AGE IN AARDI KIDS
Authors: M. A. Alshaikh
Issue Date: 2001
Abstract: The patterns of concentrations of progesterone and estrogen from one month to six months age were investigated in eight female Aardi goats. Mean plasma concentrations of estrogen and progesterone at monthly interval showed a similar trend during the study period. Estrogen concentrations increased from 2077.8 ± 157.4ng/ml at first month of age to 2334.5 ± 157.4 ng/ml at the second month of age. The concentration did not show any significant differences until animal reached six-month at which the concentration was decreased significantly to reach 1391.68 ±157.4 ng/ml. Plasma concentration of progesterone at the first two months of age, were 166.6ng/ml and 195.4ng/ml respectively. Progesterone concentration decreased after two months of age to reach 151.4 ± 12.Q ng/ml at the six month of age. Estrogen/progesterone ratio did not show any changes during the five-months age and it was then increased at six-month of age but the increase was not statistically significant. Body weight consistently increased from 6.89 kg at the first month to reach 16.59kg at the sixth month. It is therefore concluded that the inhibitory effect of estrogen is present until kids reach the six- month of age and the increase in estrogen/progesterone ratio may indicate the age of puberty
